RC6432F2871CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F2871CS is a 2.87 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film, moisture-resistant component operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 909 units in stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope. Alternative sources provide design flexibility, supply chain redundancy, and application-specific certifications such as automotive AEC-Q200 qualification.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish valid substitutes for RC6432F2871CS:

Mandatory Matching Parameters:

  • Resistance: 2.87 kOhms (exact value)
  • Tolerance: ±1% (minimum requirement)
  • Power Rating: 1W (minimum requirement)
  • Package: 2512 (6432 Metric) (exact match)
  • Composition: Thick Film
  • Temperature Coefficient: ±100ppm/°C
  • Operating Temperature: -55°C ~ 155°C (minimum coverage)
  • RoHS Status: ROHS3 Compliant

Acceptable Variations:

  • Packaging format (Tape & Reel acceptable for bulk applications)
  • Manufacturer-specific certifications (AEC-Q200 automotive qualification adds capability)
  • Moisture Sensitivity Level (MSL 1 maintained across all candidates)
  • Minor dimensional tolerances within package specification

Two substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

CRCW25122K87FKEG (Vishay Dale) - Primary Substitute

This part maintains full electrical and mechanical equivalence to the RC6432F2871CS. The Vishay Dale CRCW series is in active production status with higher inventory availability (3863 units). AEC-Q200 automotive qualification provides additional reliability assurance for applications requiring automotive-grade components. Dimensional variation (0.124" width vs. 0.126") and height increase (0.028" vs. 0.026") remain within 2512 package tolerance specifications and do not affect PCB layout compatibility. Tape & Reel packaging is suitable for automated assembly processes.

ERJ-1TNF2871U (Panasonic Electronic Components) - Secondary Substitute

This part meets all electrical specifications and package requirements. However, the product status is listed as "Not For New Designs," indicating Panasonic has discontinued this part for new applications. While 932 units are currently in stock and the part remains functionally equivalent, this designation restricts its use to legacy system support or existing design maintenance only. AEC-Q200 certification is present. Dimensional variation (0.252" length vs. 0.248") falls within package tolerance but represents the maximum specification boundary.

Selection Criteria:

  • For new designs: Use CRCW25122K87FKEG (Vishay Dale)
  • For legacy system support: ERJ-1TNF2871U (Panasonic) is acceptable if existing inventory is available
  • For automotive applications: Both CRCW25122K87FKEG and ERJ-1TNF2871U carry AEC-Q200 qualification

Frequently Asked Questions (FAQ)

Q: Can CRCW25122K87FKEG be used as a direct replacement for RC6432F2871CS?

A: Yes. Both parts share identical electrical specifications (2.87 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and are packaged in the 2512 (6432 Metric) footprint. Dimensional tolerances are within package specification. No circuit redesign is required.

Q: What is the difference between the Samsung RC6432F2871CS and Vishay Dale CRCW25122K87FKEG?

A: The primary differences are manufacturer, packaging format (bulk vs. Tape & Reel), and certifications. Samsung emphasizes moisture resistance; Vishay Dale emphasizes automotive AEC-Q200 qualification. Electrical performance and package footprint are identical.

Q: Why is ERJ-1TNF2871U marked "Not For New Designs"?

A: This designation indicates Panasonic has transitioned this part to end-of-life status and is not accepting new design-ins. Existing inventory remains available for legacy system support. New designs should use CRCW25122K87FKEG or the original RC6432F2871CS.

Q: Are there dimensional concerns when substituting these parts?

A: All three parts conform to the 2512 (6432 Metric) package specification. Minor dimensional variations (length 0.248" to 0.252", width 0.124" to 0.126", height 0.026" to 0.028") are within tolerance and do not affect PCB layout or assembly compatibility.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. RC6432F2871CS, CRCW25122K87FKEG, and ERJ-1TNF2871U are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute has the best inventory availability?

A: CRCW25122K87FKEG (Vishay Dale) has 3863 units in stock, compared to 909 units for the original Samsung part and 932 units for the Panasonic part.

Q: Can these parts be used interchangeably in automotive applications?

A: CRCW25122K87FKEG and ERJ-1TNF2871U both carry AEC-Q200 automotive qualification. The Samsung RC6432F2871CS does not list automotive certification. For automotive applications, use CRCW25122K87FKEG as the primary choice.
