RMCF1206FT23K2 Equivalent & Substitute Parts

Part Overview

The RMCF1206FT23K2 is a 23.2 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This automotive-grade thick film resistor meets AEC-Q200 qualification and is designed for high-reliability applications requiring stable performance across -55°C to 155°C operating temperature range. The part is currently in active production status with 4160 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility allows for alternative manufacturers meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

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

Resistance value: 23.2 kOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Package type: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C
RoHS compliance: ROHS3 Compliant
Moisture sensitivity: MSL 1

All substitute parts listed meet these core electrical and mechanical requirements. One part (CRCW120623K2FKEAHP) is classified as an upgrade due to higher power rating (0.75W vs 0.25W) while maintaining all other specifications.

Engineering Selection Recommendations

Direct Equivalents (0.25W, 1/4W):

CRCW120623K2FKEA (Vishay Dale) and CRCW120623K2FKEA provide the highest compatibility with AEC-Q200 automotive qualification and active production status. CRCW120623K2FKEA offers the largest available inventory (26170 units) with identical electrical specifications and automotive certification.

KTR18EZPF2322 (Rohm Semiconductor) is an active production alternative with AEC-Q200 qualification and high voltage capability, suitable for designs requiring enhanced voltage performance within the same power rating.

RC1206FR-0723K2L (YAGEO) is an active production alternative with moisture-resistant composition. This part lacks AEC-Q200 certification and is suitable for non-automotive applications.

CR1206-FX-2322ELF (Bourns Inc.) is an active production alternative with moisture-resistant composition. This part lacks AEC-Q200 certification and is suitable for non-automotive applications.

Obsolescence Consideration:

ERJ-8ENF2322V (Panasonic Electronic Components) carries "Not For New Designs" status and should be avoided for new product development despite meeting all electrical specifications and AEC-Q200 qualification.

Upgrade Option (0.75W, 3/4W):

CRCW120623K2FKEAHP (Vishay Dale) provides higher power dissipation capability (0.75W vs 0.25W) while maintaining all other electrical and mechanical parameters. This part is suitable for designs requiring increased thermal margin or pulse withstanding capability within the same package footprint.

Frequently Asked Questions (FAQ)

Q: Can CRCW120623K2FKEAHP be used as a direct replacement for RMCF1206FT23K2?

A: Yes, CRCW120623K2FKEAHP is mechanically and electrically compatible. The higher power rating (0.75W vs 0.25W) provides additional thermal margin and does not create compatibility issues in circuits designed for 0.25W operation. The 1206 package dimensions remain identical.

Q: What is the difference between parts with and without AEC-Q200 certification?

A: AEC-Q200 certification indicates automotive-grade qualification with defined reliability and performance standards. Parts without this certification are suitable for commercial and industrial applications but should not be used in automotive designs requiring this qualification.

Q: Are there dimensional differences between substitute parts?

A: All parts share the 1206 (3216 Metric) package designation. Minor variations exist in maximum seated height (0.024" to 0.030"), which do not affect PCB assembly compatibility or circuit performance.

Q: Why is ERJ-8ENF2322V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new product designs. Existing inventory remains available for legacy system support.

Q: Can moisture-resistant variants (CR1206-FX-2322ELF, RC1206FR-0723K2L) replace automotive-grade parts?

A: Moisture-resistant composition addresses environmental protection but does not provide AEC-Q200 automotive qualification. These parts are suitable for non-automotive applications where moisture resistance is required but automotive certification is not.
