Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F8661CS are qualified based on the following criteria:

Electrical Parameters: Resistance value of 8.66 kOhms, tolerance of ±1%, and power rating of 1W must be identical.

Mechanical Parameters: Package designation of 2512 (6432 Metric) ensures physical and footprint compatibility on printed circuit boards.

Environmental Parameters: Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C to 155°C must be maintained.

Composition & Construction: Thick film construction type is required for thermal and electrical performance equivalence.

Compliance & Certifications: RoHS3 compliance and MSL 1 rating ensure regulatory and manufacturing process compatibility.

The identified substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable with the original RC6432F8661CS component.

Frequently Asked Questions (FAQ)

Q: Can CRCW25128K66FKEG replace RC6432F8661CS in non-automotive applications?

A: Yes. The CRCW25128K66FKEG meets all electrical and mechanical parameters of the RC6432F8661CS. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits.

Q: Are there dimensional differences between these three parts?

A: All three parts use the 2512 (6432 Metric) package. Length is 0.248" (6.30mm) for all parts. Width varies slightly: RC6432F8661CS and RMCF2512FT8K66 are 0.126" (3.20mm), while CRCW25128K66FKEG is 0.124" (3.15mm). Height-seated maximum is 0.026" (0.66mm) for RC6432F8661CS and 0.028" (0.70mm) for both substitute parts. These dimensional variations remain within standard PCB footprint tolerances for 2512 packages.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture-related degradation. These components do not require special moisture-controlled storage or baking procedures prior to soldering.

Q: Are all three parts available in tape and reel packaging?

A: RC6432F8661CS is available in standard packaging. CRCW25128K66FKEG and RMCF2512FT8K66 are specified as Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Do these resistors meet REACH compliance?

A: Yes. All three parts are listed as REACH Unaffected, confirming compliance with REACH regulations.
