ERJ-S1DF4871U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF4871U is a 4.87 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 in active production status with 637 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require alternative qualified sources while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF4871U is determined by strict equivalence across the following critical parameters:

• Resistance value: 4.87 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

The ERJ-12SF4871U meets all electrical and mechanical substitution criteria. Differences in manufacturing series (ERJ-12S vs. ERJ-S1D) and product status do not affect functional equivalence when all specified parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S1DF4871U is the preferred selection for new designs due to its active product status. The ERJ-12SF4871U provides functional equivalence for existing designs or applications where the primary part is unavailable, though it carries a "Not For New Designs" status from the manufacturer.

Both parts satisfy identical electrical specifications, mechanical compatibility, and automotive qualification requirements. Selection between these parts should be based on design phase (new vs. existing) and inventory availability rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF4871U be used as a direct replacement for ERJ-S1DF4871U in automotive applications?

A: Yes. Both parts meet identical AEC-Q200 automotive qualification standards, operate across the same temperature range (-55°C ~ 155°C), and provide equivalent electrical performance with 4.87 kOhms ±1% resistance and 0.75W power rating in the 2010 package.

Q: What is the significance of the "Not For New Designs" status on ERJ-12SF4871U?

A: This designation indicates the manufacturer is transitioning away from this series. For new product development, ERJ-S1DF4871U should be specified. For existing designs or legacy applications, ERJ-12SF4871U remains functionally qualified.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 2010 (5025 Metric) package with identical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.028" (0.70mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8533.21.0030) codes.

Q: What is the difference between ERJ-S1D and ERJ-12S series designations?

A: These represent different manufacturing series within Panasonic's resistor portfolio. The series designation does not affect electrical or mechanical performance when all specified parameters are identical.
