The 5962 prefix sits at the center of military microcircuit procurement. It signals a part that is controlled by a Standard Microcircuit Drawing (SMD), manufactured and screened under MIL-PRF-38535, and supported by documentation that must follow the device through every change of ownership. For defense buyers, reading a 5962 part number correctly is not a paperwork exercise; it determines whether the component you install is qualified for the intended program, whether the source can prove it, and whether the lot remains traceable after delivery. This guide explains the drawing system, the part-number structure, device classes, required documentation, and how to source compliant 5962 components without creating supply-chain risk.
What the 5962 Prefix Means Under MIL-PRF-38535
A 5962 part is not a commercial component with a new label. The prefix identifies a monolithic microcircuit controlled by a Standard Microcircuit Drawing maintained by DLA Land and Maritime. The drawing defines electrical performance, package configuration, screening, quality assurance, and qualification requirements. Manufacturing flows are governed by MIL-PRF-38535, while the drawing itself remains the stable procurement baseline for the end item [1].
Under the Qualified Manufacturers List (QML) approach, suppliers are qualified to a controlled process and technology flow, and the SMD still defines the component-level requirements. That combination gives procurement teams a controlled baseline: the drawing does not change arbitrarily, and the manufacturing line is audited against MIL-PRF-38535. This is why a 5962 suffix, package code, or device class must be read as part of the drawing, not as a standalone part number.
In practice, the same control model extends across military logic, memory, data converters, and high-density digital devices. The drawing-to-lot linkage is the recurring test of whether a source actually understands military procurement.
How to Read a 5962 Part Number
The most common failure in 5962 sourcing is treating the suffix as a minor formatting detail. Every segment carries meaning. The basic structure is shown below.
| Segment | Example | What it tells you |
|---|---|---|
| 5962 | 5962 | Microcircuit SMD identity |
| Drawing number | 8770002 | DLA-assigned Standard Microcircuit Drawing |
| Suffix letters | EA, LA, MQA, VXA | Device class, package, lead finish, or drawing variant |
The six-digit or eight-digit drawing number identifies the specific SMD. The suffix letters identify the exact configuration and screening level. For example, 5962-8770002EA and 5962-8778902EA are distinct drawings; substituting one for the other without checking the SMD is not acceptable. Similarly, 5962-9078501MLA carries a different suffix and may not be interchangeable with a package variant such as VXA.
Before accepting any quote, compare the full PIN against the latest SMD revision. If the supplier cannot identify the drawing revision, the part cannot be considered compliant.
Device Classes and Screening: QML Q, QML V, and /883B
The suffix is not the only screening indicator. The device class or QML designation must also match the program requirement. The three most frequently encountered designations are QML Class Q, QML Class V, and /883B [1][2].
QML Class Q devices are manufactured on a MIL-PRF-38535-qualified line and screened for military and high-reliability applications. They are the standard baseline for many ground, naval, and avionics programs. QML Class V adds more demanding space-level controls, including radiation hardness assurance, element evaluation, and additional lot and wafer acceptance requirements for space applications.
/883B parts use MIL-STD-883 Class B screening. They remain common in legacy sustainment and redesign efforts, but they are not automatically equivalent to QML Q or V parts. The drawing and the required device class together define the acceptable configuration. A buyer who only checks the 5962 prefix without reading the class or suffix is making a decision with incomplete information.
For high-density devices, the same discipline applies: the supplier must show drawing-to-lot evidence, not just a datasheet and a part number.
Required Documentation for a Compliant 5962 Purchase
A compliant 5962 transaction is defined by evidence, not claims. Before accepting parts, require the following documentation package.
The Certificate of Conformance, often called a C of C, must list the manufacturer, complete PIN, lot number, date code, quantity, and a signed statement of conformance to the applicable SMD and MIL-PRF-38535 requirements. The C of C should match the physical marking on the component and the shipping documentation exactly.
The current SMD revision must be available for review. Test and screening records should include the lot traveler or summary data covering electrical test, temperature cycling, burn-in, and any other screens specified by the drawing. If the device is QML, the supplier should be listed on the DLA QML or show the current qualification status.
Counterfeit prevention is not optional. SAE AS5553B and DFARS 252.246-7007 impose risk-mitigation duties on defense supply chains [3][4]. For high-reliability parts, a missing lot number, a redacted C of C, or a supplier that refuses to provide marking photos should be treated as a stop condition.
Need help translating a 5962 suffix or verifying a C of C before you commit? Send the drawing number, date code, lot number, and target device class to xuansc2144@gmail.com. Include your SMD revision and any radiation or temperature requirements, and a sourcing engineer will respond with a documentation-first path.
Sourcing Compliant 5962 Components Without Introducing Gray-Market Risk
Compliant sourcing starts with drawing verification and ends with lot-level traceability. The following sequence reduces the chance of accepting a misrepresented or unqualified part.
First, confirm the manufacturer and QML status against the drawing. Second, demand lot-level traceability and clear photographs of part markings before shipment. Third, reject informal claims of “same form, fit, and function” unless the alternative is an officially recognized configuration on the same SMD. Fourth, verify that the C of C, test data, and physical markings all agree with the drawing revision [5].
For obsolete or long-lead 5962 devices, independent distribution becomes necessary. In that case, evaluate the supplier’s quality system, counterfeit mitigation process, and ability to provide original manufacturer documentation. AS6081 and AS9120 provide useful frameworks for distributor quality and aerospace procurement, but they do not replace your own drawing-level review.
The same acquisition discipline applies when a 5962 drawing points to high-density FPGAs, DSPs, or high-speed data converters. If the device is offered as a military drawing or a QML-qualified part, the supplier must demonstrate the same drawing-to-lot linkage. If the datasheet and C of C do not align with the SMD revision, stop and resolve the mismatch before accepting the quote.
The same traceability rule applies when a 5962 drawing points to a high-density FPGA or processor. <A1020B-PG84B ACT2 FPGA: Specs, Sourcing, and Availability> covers ACT2 military FPGA sourcing and availability.
For more complex Ku085 devices, the drawing-to-lot discipline remains the primary risk control. <UltraScale KU085 FPGA Specifications for Defense Systems> covers defense FPGA specifications and sourcing.
When packaging, thermal, and reliability data sit alongside a military drawing, the evaluation becomes measurably stronger. <Virtex-7 690T FPGA: Performance, Packaging, and Reliability Insights> covers performance, packaging, and reliability insights.

FAQ
What does the 5962 prefix mean on a military microcircuit?
The 5962 prefix identifies a microcircuit controlled by a Standard Microcircuit Drawing. The drawing defines the electrical, mechanical, screening, and qualification requirements for the part [1].
How do QML Q and QML V differ?
QML Class Q is the military and high-reliability baseline manufactured on a MIL-PRF-38535-qualified line. QML Class V adds space-level controls, including radiation hardness assurance and more demanding lot and wafer acceptance requirements [1][2].
What should a compliant 5962 C of C include?
A compliant C of C should list the manufacturer, complete PIN, lot number, date code, quantity, and a signed statement of conformance to the applicable SMD and MIL-PRF-38535 requirements. It must match the physical marking and shipping documentation.
Can a commercial part be upscreened to a 5962 configuration?
Generally, no. A commercial part screened after manufacture does not become a QML or SMD-compliant 5962 device unless the drawing and qualification framework explicitly permit that path. The part must be procured to the SMD from an approved manufacturing source.
How do I verify a 5962 part is not counterfeit?
Require lot-level traceability, marking photographs, a manufacturer C of C, and test or screening records. Compare all data against the SMD revision. SAE AS5553B and DFARS 252.246-7007 define risk-mitigation duties for defense supply chains [3][4].
Do all 5962 parts include radiation hardness assurance?
No. Radiation hardness assurance is typically specified for QML Class V or for SMDs that contain explicit radiation requirements. A standard QML Class Q device does not automatically carry that assurance.
