RMCF2010FT2K21 Equivalent & Substitute Parts

Part Overview

The RMCF2010FT2K21 is a 2.21 kOhms ±1% 0.75W chip resistor in 2010 (5025 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 active in production with 2153 units in stock. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility is required while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMCF2010FT2K21 are qualified based on the following critical parameters:

• Resistance value: 2.21 kOhms
• Tolerance: ±1%
• Power rating: 0.75W minimum
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitutes meet these electrical and mechanical specifications. Variations in specific features (such as automotive AEC-Q200 certification or moisture resistance designation) are noted but do not disqualify substitution when the core parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and full RoHS3 compliance. The RMCF2010FT2K21 (Stackpole Electronics Inc) and CRCW20102K21FKEF (Vishay Dale) both carry AEC-Q200 automotive qualification. The RC2010FK-072K21L (YAGEO) is designated as moisture resistant and offers a slightly reduced seated height of 0.026" (0.65mm) compared to 0.028" (0.70mm) for the other two parts. This height difference is within typical PCB assembly tolerances and does not affect electrical performance or mechanical fit in standard 2010 package footprints.

Selection between these parts should be based on supply availability, cost considerations, and any design-specific requirements for automotive certification or moisture resistance features.

Frequently Asked Questions (FAQ)

Q: Can CRCW20102K21FKEF replace RMCF2010FT2K21 in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, share identical electrical specifications (2.21 kOhms ±1%, 0.75W), and use the same 2010 (5025 Metric) package. They are electrically and mechanically interchangeable.

Q: What is the difference between the YAGEO RC2010FK-072K21L and the other substitutes?

A: The RC2010FK-072K21L is designated as moisture resistant and has a maximum seated height of 0.026" (0.65mm) versus 0.028" (0.70mm) for the Stackpole and Vishay parts. All other electrical and mechanical parameters are identical. The height difference is negligible for standard PCB assembly.

Q: Are all three parts RoHS3 compliant?

A: Yes. RMCF2010FT2K21, CRCW20102K21FKEF, and RC2010FK-072K21L are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts share the same 2010 (5025 Metric) package footprint, identical electrical specifications, and compatible termination configuration. They can be used interchangeably without PCB redesign.

Q: Which part should I select if automotive AEC-Q200 certification is required?

A: Both RMCF2010FT2K21 (Stackpole) and CRCW20102K21FKEF (Vishay Dale) carry explicit AEC-Q200 qualification. The RC2010FK-072K21L does not list this certification in the provided specifications.
