Equivalent & Substitute Parts for ERJ-S1DF3480U

Part Overview

The ERJ-S1DF3480U is a 348 Ohms ±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 909 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design revisions require alternative qualified sources, or when supply chain optimization requires multi-source qualification. The substitute parts listed maintain identical electrical specifications and package dimensions while offering alternative manufacturing sources and feature sets.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF3480U is determined by strict equivalence across the following parameters:

• Resistance value: 348 Ohms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• 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 criteria. Variations in product status, inventory levels, and optional features (such as anti-sulfur or moisture-resistant coatings) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For new designs, select from parts with Active product status: ERJ-S1DF3480U (Panasonic), AC2010FK-07348RL (YAGEO), or CRCW2010348RFKEF (Vishay Dale). All three maintain full AEC-Q200 automotive qualification and ROHS3 compliance.

The ERJ-12SF3480U carries a "Not For New Designs" status and should be used only for legacy design maintenance or when existing qualification documentation specifically references this part number.

For supply chain resilience, multi-source qualification across Panasonic, YAGEO, and Vishay Dale sources ensures design continuity and mitigates single-source supply risk.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF3480U be used in new automotive designs? A: No. The ERJ-12SF3480U is marked "Not For New Designs." Use ERJ-S1DF3480U, AC2010FK-07348RL, or CRCW2010348RFKEF for new designs.

Q: Are all substitute parts mechanically compatible with the ERJ-S1DF3480U? A: Yes. All substitute parts use the 2010 (5025 Metric) package with identical footprint dimensions (0.197" L x 0.098" W). Maximum seated heights vary between 0.026" and 0.028", which is within standard PCB assembly tolerances.

Q: Do substitute parts maintain the same electrical performance? A: Yes. All substitute parts share identical resistance (348 Ohms), tolerance (±1%), power rating (0.75W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C).

Q: What is the difference between anti-sulfur and moisture-resistant coatings? A: Anti-sulfur coating (ERJ-S1DF3480U) protects against hydrogen sulfide exposure in harsh environments. Moisture-resistant coating (AC2010FK-07348RL) enhances performance in high-humidity conditions. Both are optional features that do not affect core electrical specifications or substitution eligibility.

Q: Are all parts RoHS3 compliant? A: Yes. All listed parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
