Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and full RoHS3 compliance. Selection between the main part and substitutes is determined by availability and application requirements:

RC6432F7871CS (Samsung Electro-Mechanics): Primary selection when Samsung sourcing is specified or preferred. Moisture-resistant construction with MSL 1 rating. Current inventory: 1094 units.

CRCW25127K87FKEG (Vishay Dale): Qualified substitute with AEC-Q200 automotive certification. Suitable for applications requiring automotive-grade components. Tape & Reel packaging. Current inventory: 2434 units. Seated height maximum 0.028" (0.70mm) versus 0.026" (0.66mm) for main part.

RMCF2512FT7K87 (Stackpole Electronics Inc): Qualified substitute with AEC-Q200 automotive certification. Suitable for applications requiring automotive-grade components. Tape & Reel packaging. Current inventory: 9019 units. Seated height maximum 0.028" (0.70mm) versus 0.026" (0.66mm) for main part. Highest inventory availability.

All three parts are electrically and mechanically interchangeable within the specified parameters. Physical dimension variations (width 0.124" to 0.126", height 0.026" to 0.028") fall within standard PCB layout tolerances for 2512 package footprints.

Frequently Asked Questions (FAQ)

Q: Can CRCW25127K87FKEG or RMCF2512FT7K87 be used as direct replacements for RC6432F7871CS?

A: Yes. Both substitute parts match the electrical specifications (7.87 kOhms ±1%, 1W, ±100ppm/°C), construction type (thick film), and package format (2512 / 6432 Metric). All three parts operate across -55°C to 155°C and maintain MSL 1 rating with RoHS3 compliance.

Q: What is the difference between the main part and substitutes?

A: The primary differences are manufacturer and packaging format. RC6432F7871CS is supplied by Samsung Electro-Mechanics. CRCW25127K87FKEG and RMCF2512FT7K87 are supplied by Vishay Dale and Stackpole Electronics Inc respectively, both with AEC-Q200 automotive certification. The substitutes are supplied in Tape & Reel format. Seated height specifications vary slightly (0.026" to 0.028" maximum), which is within standard PCB design tolerances.

Q: Are there any compatibility concerns with PCB layout?

A: No. All three parts use the identical 2512 (6432 Metric) package footprint. The minor dimensional variations in width (0.124" to 0.126") and height (0.026" to 0.028") are within standard manufacturing tolerances and PCB design margins for this package class.

Q: Which substitute should be selected for automotive applications?

A: Both CRCW25127K87FKEG and RMCF2512FT7K87 carry AEC-Q200 automotive certification. Selection between these two is based on availability and supplier preference. RMCF2512FT7K87 currently has higher inventory (9019 units).

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture baking requirements. All three parts carry this rating, eliminating moisture management concerns during storage and handling.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, within the specified electrical and mechanical parameters. No design changes are required. The parts are pin-compatible and functionally equivalent for the 7.87 kOhms ±1% 1W 2512 resistor application.
