Substitute Part Grouping Explanation

Substitute parts for the RC5025F2431CS are identified based on the following substitution criteria:

Electrical Parameters (Critical Match Required):

• Resistance value: 2.43 kOhms (exact match)
• Tolerance: ±1% (equal or tighter tolerance acceptable)
• Temperature coefficient: ±100ppm/°C (matching thermal stability)
• Operating temperature range: -55°C ~ 155°C (minimum coverage required)

Mechanical Parameters (Compatibility Required):

• Package type: 2010 (5025 Metric) (identical footprint and land pattern)
• Composition: Thick Film (same technology class)
• Number of terminations: 2 (standard two-terminal configuration)

Power Rating (Upgrade Acceptable):

• Minimum power rating: 0.667W (higher ratings are acceptable for thermal margin)

Compliance Parameters (Regulatory Alignment):

• RoHS3 compliance (mandatory for regulated markets)
• Moisture sensitivity level: MSL 1 (unlimited handling flexibility)

The RMCF2010FT2K43 qualifies as a substitute based on matching all critical electrical parameters, identical package dimensions, and equivalent compliance certifications, with the additional benefit of higher power rating (0.75W vs. 0.667W).

Engineering Selection Recommendations

Primary Selection (RC5025F2431CS): Select the RC5025F2431CS when Samsung Electro-Mechanics supply chain preference is established or when moisture-resistant thick film composition from this specific manufacturer is required. This part maintains Active product status with full ROHS3 compliance and unlimited MSL rating.

Substitute Selection (RMCF2010FT2K43): The RMCF2010FT2K43 from Stackpole Electronics Inc is functionally equivalent and directly substitutable. This part provides identical electrical specifications (2.43 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C operating range) and mechanical compatibility (2010 package, 5.00mm x 2.50mm footprint). The substitute offers a higher power rating (0.75W vs. 0.667W), providing additional thermal margin in power-dissipation-sensitive applications. The RMCF2010FT2K43 includes AEC-Q200 automotive qualification, making it suitable for automotive-grade applications where the main part specification does not explicitly include automotive certification. Both parts are ROHS3 compliant with MSL 1 rating and Active product status.

Interchangeability Basis: Direct pin-for-pin and footprint-compatible substitution is supported. The 0.002" (0.04mm) height difference between parts is negligible for standard PCB assembly and does not affect component placement or clearance in typical circuit designs.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT2K43 be used as a direct replacement for RC5025F2431CS in production?

A: Yes. The RMCF2010FT2K43 is directly substitutable. Both parts share identical resistance value (2.43 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and package footprint (2010 / 5025 Metric). The substitute's higher power rating (0.75W vs. 0.667W) provides thermal margin without affecting circuit function.

Q: Are there any height or footprint differences that affect PCB assembly?

A: The seated height difference is 0.002" (0.04mm), with RMCF2010FT2K43 at 0.028" maximum versus RC5025F2431CS at 0.026" maximum. This negligible difference does not impact standard PCB assembly, component placement, or clearance requirements. Both parts use identical 2010 (5025 Metric) package dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm).

Q: Do both parts meet the same regulatory compliance requirements?

A: Yes. Both RC5025F2431CS and RMCF2010FT2K43 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity level. The RMCF2010FT2K43 includes additional AEC-Q200 automotive qualification, which is not specified for the main part but does not create incompatibility.

Q: What is the difference between the two manufacturers' thick film technology?

A: Both parts use thick film composition with identical temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C). Manufacturer-specific process variations do not affect electrical performance within the specified tolerance and temperature coefficient parameters.

Q: Can the substitute be used in applications requiring moisture-resistant characteristics?

A: Yes. The RMCF2010FT2K43 is a thick film chip resistor with MSL 1 rating, indicating unlimited moisture sensitivity level. Both parts provide equivalent moisture resistance for general industrial and consumer applications.

Q: Is the higher power rating of RMCF2010FT2K43 a concern for circuit design?

A: No. A higher power rating is a beneficial characteristic that provides additional thermal dissipation margin. The substitute's 0.75W rating exceeds the minimum 0.667W requirement, allowing for greater power handling without affecting circuit performance or introducing design complications.

Q: Are there packaging differences between the two parts?

A: The RC5025F2431CS is supplied in standard packaging (not specified in detail), while RMCF2010FT2K43 is supplied in Tape & Reel (TR) format. Both use identical 2010 package type. Tape & Reel packaging is standard for automated assembly and does not affect component electrical or mechanical properties.
