ERJ-S1DF2871U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF2871U is a 2.87 kOhms ±1% 0.75W chip resistor in 2010 (5025 Metric) package manufactured by Panasonic Electronic Components. This thick film resistor features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in automotive and industrial environments. The part is currently Active in product status with 1008 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design flexibility is required across multiple suppliers, or when production volumes demand alternative sourcing options while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF2871U is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.87 kOhms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All substitute parts listed meet these parameters without exception. Substitution is valid across manufacturers (Panasonic, Vishay Dale, Stackpole Electronics) provided all electrical and mechanical specifications remain identical.

Engineering Selection Recommendations

Primary Selection (Active Status):

• ERJ-S1DF2871U (Panasonic) — Recommended for new designs. Active product status with anti-sulfur feature specification.
• CRCW20102K87FKEF (Vishay Dale) — Active status alternative with highest inventory availability (9946 units).
• RMCF2010FT2K87 (Stackpole Electronics) — Active status alternative with established automotive supply chain.

Secondary Selection (Legacy Status):

• ERJ-12SF2871U (Panasonic) — Not recommended for new designs. Suitable only for legacy system maintenance or existing production lines where design continuity is required. Highest inventory (10880 units) available for ongoing support.

All listed parts carry identical electrical specifications, AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. Selection should be based on supplier availability, lead time requirements, and existing supply chain relationships.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF2871U be used in place of ERJ-S1DF2871U in new designs? A: No. ERJ-12SF2871U carries "Not For New Designs" status. While electrically and mechanically equivalent, it is designated for legacy applications only. Use ERJ-S1DF2871U, CRCW20102K87FKEF, or RMCF2010FT2K87 for new designs.

Q: Are all substitute parts identical in package dimensions? A: Yes. All parts use the 2010 (5025 Metric) package with identical dimensions: 0.197" L × 0.098" W (5.00mm × 2.50mm) and maximum seated height of 0.028" (0.70mm).

Q: Do all substitute parts meet automotive qualification requirements? A: Yes. All listed parts carry AEC-Q200 automotive qualification and operate across the identical temperature range of -55°C to 155°C with ±100ppm/°C temperature coefficient.

Q: What is the difference between ERJ-S1DF2871U and ERJ-12SF2871U? A: Both are Panasonic 2.87 kΩ ±1% 0.75W resistors in 2010 package. The primary difference is product status: ERJ-S1DF2871U is Active (recommended for new designs), while ERJ-12SF2871U is Not For New Designs (legacy support only). ERJ-S1DF2871U includes anti-sulfur feature specification.

Q: Are cross-manufacturer substitutions electrically valid? A: Yes. Vishay Dale CRCW20102K87FKEF and Stackpole Electronics RMCF2010FT2K87 are electrically and mechanically equivalent to Panasonic parts. All meet identical specifications for resistance, tolerance, power rating, temperature coefficient, operating range, and automotive qualification.

Q: What is MSL 1 rating significance? A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life with no special moisture control requirements during storage or handling. All listed parts carry this rating.
