Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCF2512FT866R is determined by strict equivalence across the following parameters:

Resistance value must be 866 Ohms with ±1% tolerance. Power rating must be 1W. Package must be 2512 (6432 Metric) with identical termination count (2 terminations). Composition must be thick film. Temperature coefficient must be ±100ppm/°C. Operating temperature range must span -55°C to 155°C. Automotive qualification must include AEC-Q200 certification. RoHS3 compliance and MSL 1 rating must be maintained.

The CRCW2512866RFKEG from Vishay Dale meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the RMCF2512FT866R and CRCW2512866RFKEG are active production parts with full AEC-Q200 automotive qualification. Selection between these parts should be based on availability, supply chain considerations, and procurement lead times. Both parts maintain ROHS3 compliance and identical electrical and thermal characteristics. The mechanical dimensions are equivalent within tolerance, with the Vishay Dale part measuring 0.248" L x 0.124" W compared to the Stackpole part at 0.248" L x 0.126" W, both with 0.028" maximum seated height. Both parts are suitable for direct substitution in automotive applications requiring 866 Ohm 1W thick film resistors.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512866RFKEG replace RMCF2512FT866R in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified with identical electrical specifications (866 Ohms ±1%, 1W, ±100ppm/°C), the same 2512 package, and equivalent operating temperature ranges (-55°C to 155°C). Mechanical dimensions are equivalent within standard tolerances.

Q: Are there any dimensional differences between these parts?

A: The width specification differs slightly: RMCF2512FT866R is 0.126" W while CRCW2512866RFKEG is 0.124" W. Both are within the 2512 package specification and do not affect PCB layout or assembly compatibility.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity concerns for storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both RMCF2512FT866R and CRCW2512866RFKEG are ROHS3 compliant.

Q: What is the temperature coefficient specification for these resistors?

A: Both parts have a temperature coefficient of ±100ppm/°C across the -55°C to 155°C operating range.
