Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F2211CS are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 2.21 kOhms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture resistance: Required
• RoHS3 compliance: Required
• MSL rating: 1 (Unlimited)

Allowable Variation:

• Power rating: Substitutes with equal (0.667W) or higher power ratings (0.75W, 3/4W) are acceptable, as higher power ratings provide equal or superior thermal performance in the same package footprint.

Substitute Classification:

Upgrade Substitutes – Higher power rating with identical electrical specifications:

• RC2010FK-072K21L (YAGEO): 0.75W rating

Similar Substitutes – Higher power rating with automotive-grade certification:

• CRCW20102K21FKEF (Vishay Dale): 0.75W rating, AEC-Q200 qualified
• RMCF2010FT2K21 (Stackpole Electronics Inc): 0.75W rating, AEC-Q200 qualified

Parameter Comparison

Engineering Selection Recommendations

For General-Purpose Applications: RC2010FK-072K21L (YAGEO) is the direct upgrade substitute. It maintains all electrical and mechanical specifications of the RC5025F2211CS while providing increased power dissipation capability (0.75W vs. 0.667W) within the identical 2010 package footprint. This substitution is suitable for applications where the original specification is met or exceeded.

For Automotive or High-Reliability Applications: CRCW20102K21FKEF (Vishay Dale) or RMCF2010FT2K21 (Stackpole Electronics Inc) are qualified substitutes. Both components carry AEC-Q200 automotive-grade certification and provide the same 0.75W power rating. Selection between these two depends on supply chain availability and preferred supplier qualification status. Both are ROHS3 compliant with MSL 1 rating.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original RC5025F2211CS specifications. No additional compliance verification is required for direct substitution in existing designs.

Physical Compatibility: All substitute parts are housed in the 2010 (5025 Metric) package with identical length and width (5.00mm x 2.50mm). Maximum seated height varies slightly (0.026" to 0.028"), which remains within standard PCB assembly tolerances and does not affect component placement or functionality.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-072K21L replace RC5025F2211CS in my circuit?

A: Yes. RC2010FK-072K21L is a direct substitute with identical electrical specifications (2.21 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C operating range) and package format (2010 Metric). The higher power rating (0.75W vs. 0.667W) provides additional thermal margin without affecting circuit performance.

Q: What is the difference between the YAGEO and Vishay Dale substitutes?

A: RC2010FK-072K21L (YAGEO) is a general-purpose substitute with identical specifications. CRCW20102K21FKEF (Vishay Dale) is an automotive-grade equivalent with AEC-Q200 certification. Both have 0.75W power ratings and identical electrical parameters. Selection depends on application requirements and supplier availability.

Q: Are the substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the 2010 (5025 Metric) package with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm). Maximum seated height ranges from 0.026" to 0.028", which is within standard PCB assembly tolerances and does not require footprint modification.

Q: Do I need to re-qualify my design if I use a substitute part?

A: No re-qualification is required for electrical performance, as all substitutes maintain identical resistance, tolerance, temperature coefficient, and operating temperature range. If your design uses AEC-Q200 certification as a requirement, select CRCW20102K21FKEF or RMCF2010FT2K21. All parts maintain ROHS3 compliance and MSL 1 rating.

Q: What is the advantage of the higher power rating in substitute parts?

A: The 0.75W rating in substitute parts (vs. 0.667W in the original) provides improved thermal performance and greater safety margin in power dissipation. In the same 2010 package footprint, this allows the component to operate at lower junction temperatures under identical load conditions, extending component life and reliability.

Q: Can I use CRCW20102K21FKEF or RMCF2010FT2K21 in non-automotive applications?

A: Yes. Automotive-grade components (AEC-Q200 certified) exceed the performance and reliability requirements of general-purpose applications. These parts are fully compatible with non-automotive designs and provide enhanced reliability margins.

Q: Are all substitute parts in stock?

A: Inventory status is subject to change. RC2010FK-072K21L (YAGEO) has 9,070 pieces available. CRCW20102K21FKEF (Vishay Dale) has 14,965 pieces available. RMCF2010FT2K21 (Stackpole) has 2,153 pieces available. Verify current availability with your supplier before design finalization.
