SG1525AJ/883B Technical Overview: Verified Parameters Before Sourcing
MICROCHIP SG1525AJ/883B is a power-management device cataloged in Power Modules & Discretes for Aerospace & Defense 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 Output Current 200 mA source / sink continuous class, Package/Case 16-pin ceramic DIP (J package), Device Type Voltage-mode regulating PWM controller, Supply Voltage 8 V to 35 V.
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 SG1525AJ/883B requirement.

What the Specifications Mean in a Design Review
For this power-management device, the main compatibility checks are input range, output level, power rating, efficiency, isolation, thermal design and protection behavior. 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:
- Output Current: 200 mA source / sink continuous class
- Package/Case: 16-pin ceramic DIP (J package)
- Device Type: Voltage-mode regulating PWM controller
- Supply Voltage: 8 V to 35 V
- Oscillator Frequency: 100 Hz to 500 kHz
- Reference Voltage: 5.1 V ±1%
- Output Configuration: Dual source/sink totem-pole drivers
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.
SG1525AJ/883B and Related MICROCHIP Devices
The following pages provide useful internal comparison points. They are related sourcing options, not automatically drop-in replacements:
- MICROCHIP MIC4427YM — compare the exact architecture, package, speed or grade before substitution.
- MICROCHIP S25FL216K0PMFI01 — compare the exact architecture, package, speed or grade before substitution.
- MICROCHIP MIC5265-1 8YD5-TR — compare the exact architecture, package, speed or grade before substitution.
- MICROCHIP MRT130KP275CA — 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 SG1525AJ/883B 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 Power Modules & Discretes selection.
Applications and Procurement Context
SG1525AJ/883B may be evaluated for Aerospace & Defense 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.
