M83421/06-1255R Technical Overview: Verified Parameters Before Sourcing
DEARBORN M83421/06-1255R is a high-reliability passive or interconnect component cataloged in Passives & Connectors (MIL-SPEC) for Aerospace & Defense, Avionics Systems programs. Unlike a family-level listing, the complete ordering code matters: package, temperature grade, speed option, screening level and shipment format can change with a suffix. The structured reference data for this exact part identifies Capacitance 1.0 µF, Tolerance ±1%, DC Rated Voltage 30 VDC, Capacitor Style CRH31 hermetically sealed metallized film.
These values are useful for initial BOM and sourcing review, but engineering approval should still use the latest manufacturer-controlled datasheet, package drawing and change notices. For availability, lot/date code and documentation, send Sparkle Electronics the complete M83421/06-1255R requirement.

What the Specifications Mean in a Design Review
For this high-reliability passive or interconnect component, the main compatibility checks are value, tolerance, voltage or current rating, dielectric/material system, termination, package and environmental qualification. A replacement should not be approved from the family name alone. The values below need to be checked against the schematic, PCB footprint, power tree, timing constraints, thermal analysis and program qualification baseline:
- Capacitance: 1.0 µF
- Tolerance: ±1%
- DC Rated Voltage: 30 VDC
- Capacitor Style: CRH31 hermetically sealed metallized film
- Dielectric: Polyphenylene sulfide (PPS)
- AC Rating at 0–400 Hz: 22 V / 0.055 A
- AC Rating at 4 kHz: 22 V / 0.550 A
Minimum and maximum values are not interchangeable with typical test values, and package-level compatibility does not guarantee pin, timing or firmware compatibility. Where the assembly is used in high-reliability equipment, confirm the required screening, traceability, lead finish and environmental documentation before purchase.
M83421/06-1255R and Related DEARBORN Devices
The following pages provide useful internal comparison points. They are related sourcing options, not automatically drop-in replacements:
- DEARBORN M83421/06-1244R — compare the exact architecture, package, speed or grade before substitution.
- DEARBORN M83421/06-1166R — compare the exact architecture, package, speed or grade before substitution.
- DEARBORN M83421/06-1172R — compare the exact architecture, package, speed or grade before substitution.
- DEARBORN M83421/06-1256R — compare the exact architecture, package, speed or grade before substitution.
When comparing these devices, start with the exact function and architecture, then verify package and pinout, voltage rails, speed or bandwidth, operating temperature and qualification grade. If any of those differ, an engineering redesign or requalification may be required.
Package, Temperature and Ordering-Code Checks
The orderable code M83421/06-1255R must be kept intact on the RFQ. Confirm the manufacturer marking, package drawing, terminal finish, moisture handling, operating-temperature requirement and packing format. For obsolete or long-stored material, define acceptable date codes and inspection criteria before quotation rather than after delivery.
Sourcing teams should also request the documentation appropriate to the program: Certificate of Conformance, packing and label photographs, lot/date-code information, traceability, visual inspection, X-ray or electrical testing when required. See our quality-control approach and the broader Passives & Connectors (MIL-SPEC) selection.
Applications and Procurement Context
M83421/06-1255R may be evaluated for Aerospace & Defense, Avionics Systems systems where its verified electrical limits, package and temperature range match the approved design. Typical work includes new production, repair, lifecycle extension and last-time-buy planning. Application labels describe catalog relevance; final suitability remains a system-level engineering decision.
