RMCF2512FT23K7 Equivalent & Substitute Parts

Part Overview

The RMCF2512FT23K7 is a 23.7 kOhms ±1% 1W chip resistor in 2512 (6432 Metric) package manufactured by Stackpole Electronics Inc. This thick film resistor is designed for automotive applications and meets AEC-Q200 qualification standards. The part is currently in active production status with 1072 units available in inventory.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified manufacturers is needed while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCF2512FT23K7 is determined by strict equivalence across the following parameters:

• Resistance value: 23.7 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All substitute parts listed meet these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

CRCW251223K7FKEG (Vishay Dale) is the primary recommended substitute. This part maintains active production status and meets all electrical and mechanical specifications identical to the RMCF2512FT23K7. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance. Inventory availability for the Vishay part is 1872 units, providing supply security.

ERJ-1TNF2372U (Panasonic Electronic Components) is an electrically equivalent alternative; however, this part carries a "Not For New Designs" product status designation. While it meets all electrical and mechanical parameters and maintains AEC-Q200 qualification and ROHS3 compliance, its discontinued design status makes it suitable only for legacy system support or existing production lines where supply continuity is already established. Panasonic inventory for this part is 957 units.

For new designs and ongoing production, CRCW251223K7FKEG is the preferred substitute choice due to active product status and superior inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CRCW251223K7FKEG be used as a direct replacement for RMCF2512FT23K7?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance (23.7 kOhms), tolerance (±1%), power rating (1W), package (2512), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). Dimensional variations are within acceptable PCB assembly tolerances.

Q: Why is ERJ-1TNF2372U marked "Not For New Designs"?

A: This designation indicates the part is in end-of-life phase and Panasonic is not recommending it for new product development. While the part remains electrically and mechanically equivalent and maintains full AEC-Q200 qualification, it should be reserved for legacy system maintenance or existing production continuity only.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within the 2512 package specification. RMCF2512FT23K7 measures 0.248" L x 0.126" W, CRCW251223K7FKEG measures 0.248" L x 0.124" W, and ERJ-1TNF2372U measures 0.252" L x 0.126" W. All three maintain the same 0.028" maximum seated height. These variations fall within standard PCB design tolerances and do not affect interchangeability.

Q: Do all three parts meet automotive standards?

A: Yes. All three parts carry AEC-Q200 qualification and ROHS3 compliance, meeting automotive industry requirements for reliability and environmental compliance.

Q: Which part should be selected for a new automotive design?

A: CRCW251223K7FKEG is the recommended choice for new designs due to active production status and highest inventory availability (1872 units). RMCF2512FT23K7 is also acceptable as the primary part number. ERJ-1TNF2372U should not be selected for new designs.
