Substitute Part Grouping Explanation

Substitute parts for the RC5025F242CS are classified based on strict adherence to the following substitution criteria:

Primary Substitution Criteria (Must Match):

• Resistance value: 2.4 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)

Secondary Consideration (Allowable Variation):

• Power rating: Substitute parts rated at 0.75W (3/4W) or higher are acceptable as they exceed the original 0.667W (2/3W) specification, providing equivalent or superior thermal performance in the same package footprint.

All identified substitute parts meet these criteria and maintain full electrical and mechanical compatibility with the RC5025F242CS.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain full compatibility with the RC5025F242CS based on electrical and mechanical parameters. Selection between alternatives is determined by application-specific requirements and supply chain considerations:

RC2010FK-072K4L (YAGEO): This upgrade substitute provides increased power rating (0.75W vs. 0.667W) in an identical package footprint. YAGEO maintains Active product status with ROHS3 compliance and MSL 1 rating. This part is suitable for general industrial applications requiring enhanced thermal margin.

CRCW20102K40FKEF (Vishay Dale): This substitute incorporates AEC-Q200 automotive qualification in addition to the base electrical and mechanical specifications. The automotive rating provides additional process control and reliability documentation suitable for automotive and mission-critical applications. Identical package dimensions and electrical performance to RC2010FK-072K4L.

RMCF2010FT2K40 (Stackpole Electronics Inc): This substitute also incorporates AEC-Q200 automotive qualification with equivalent electrical specifications and package compatibility. Stackpole maintains Active product status with ROHS3 compliance and MSL 1 rating. Selection between Vishay Dale and Stackpole automotive-qualified options is based on supply availability and procurement preferences.

All substitute parts are REACH Unaffected and classified under ECCN EAR99 with identical HTSUS coding (8533.21.0030) to the original part.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-072K4L replace RC5025F242CS in all applications?

A: Yes. RC2010FK-072K4L maintains identical electrical specifications (2.4 kOhms ±1%, ±100ppm/°C, -55°C to 155°C) and mechanical compatibility (2010 package, 5.00mm x 2.50mm). The increased power rating (0.75W vs. 0.667W) provides superior thermal performance in the same footprint and does not create compatibility issues.

Q: What is the difference between the YAGEO part and the automotive-qualified alternatives?

A: RC2010FK-072K4L (YAGEO) provides standard industrial-grade specifications. CRCW20102K40FKEF (Vishay Dale) and RMCF2010FT2K40 (Stackpole) include AEC-Q200 automotive qualification, which certifies enhanced process control, reliability testing, and documentation standards required for automotive applications. Electrical and mechanical performance are equivalent across all three parts.

Q: Are there packaging differences between these substitute parts?

A: All substitute parts use the 2010 (5025 Metric) package with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm). Height variations are minimal (0.026" to 0.028" seated maximum), which do not affect PCB layout compatibility. All parts are available in Tape & Reel (TR) packaging format.

Q: Do all substitute parts meet the same compliance standards as the original RC5025F242CS?

A: Yes. All substitute parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99 with MSL 1 (Unlimited) moisture sensitivity rating. Compliance documentation is equivalent across all identified parts.

Q: Which substitute part should be selected for new designs?

A: Selection depends on application requirements. For general industrial use, RC2010FK-072K4L offers cost-effective substitution with improved thermal margin. For automotive or mission-critical applications, CRCW20102K40FKEF or RMCF2010FT2K40 provide AEC-Q200 qualification with equivalent performance. All parts maintain Active product status with established supply availability.

Q: Are there any thermal or reliability differences between these parts?

A: All parts share identical temperature coefficient (±100ppm/°C) and operating range (-55°C to 155°C). Substitute parts with 0.75W rating provide additional thermal headroom compared to the original 0.667W specification. Thick film composition and moisture-resistant construction are consistent across all parts.
