RMCF2010FT866R Equivalent & Substitute Parts

Part Overview

The RMCF2010FT866R is a 866 Ohm ±1% 0.75W thick film chip resistor in 2010 (5025 Metric) package manufactured by Stackpole Electronics Inc. This component is rated for automotive applications under AEC-Q200 standard and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with 869 pieces available in inventory.

Substitute parts are necessary when the primary manufacturer experiences supply constraints, when design requirements mandate alternative qualified suppliers, or when inventory availability necessitates cross-manufacturer sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RMCF2010FT866R is determined by strict equivalence across the following parameters: resistance value (866 Ohms), tolerance (±1%), power rating (0.75W), package type (2010 / 5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). All identified substitute parts meet these criteria without exception.

The substitute parts listed below are direct functional equivalents suitable for one-to-one replacement in applications requiring the RMCF2010FT866R specification.

Parameter Comparison

Engineering Selection Recommendations

CRCW2010866RFKEF (Vishay Dale) is the primary recommended substitute. This part maintains active production status, carries full AEC-Q200 automotive qualification, and demonstrates equivalent electrical and mechanical specifications to the RMCF2010FT866R. Inventory availability is substantial at 8200 pieces.

ERJ-12SF8660U (Panasonic Electronic Components) is a secondary substitute option. While all electrical and mechanical parameters are identical to the primary part, this component carries a "Not For New Designs" product status designation. This part is suitable for legacy system maintenance and repair applications where the original specification must be maintained. Current inventory is 2520 pieces.

Selection between these substitutes should prioritize CRCW2010866RFKEF for new designs and active production applications. ERJ-12SF8660U is appropriate only for field replacement and legacy support scenarios.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010866RFKEF be used as a direct replacement for RMCF2010FT866R?

A: Yes. Both parts are 866 Ohm ±1% 0.75W thick film resistors in 2010 package with identical temperature coefficients, operating ranges, and AEC-Q200 automotive ratings. Electrical and mechanical compatibility is complete.

Q: What is the significance of ERJ-12SF8660U being marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development and production planning for this part series. While the part remains functionally equivalent and suitable for replacement applications, it should not be selected for new product designs or long-term production commitments.

Q: Are all three parts suitable for automotive applications?

A: Yes. RMCF2010FT866R, CRCW2010866RFKEF, and ERJ-12SF8660U all carry AEC-Q200 automotive qualification and are rated for the same operating temperature range (-55°C to 155°C).

Q: Do these parts have identical physical dimensions?

A: Yes. All three parts conform to the 2010 (5025 Metric) package standard with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.028" (0.70mm).

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

Q: Are these parts RoHS compliant?

A: Yes. RMCF2010FT866R, CRCW2010866RFKEF, and ERJ-12SF8660U are all ROHS3 compliant.
