ERJ-S14F2671U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F2671U is a 2.67 kOhms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This part 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 832 pieces available 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. The ERJ-14NF2671U represents a direct functional equivalent from the same manufacturer with identical electrical specifications but different product lifecycle status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2671U is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.67 kOhms
• Tolerance: ±1%
• Power rating: 0.5W
• Package: 1210 (3225 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

The ERJ-14NF2671U meets all these criteria and is classified as a direct substitute. This part maintains identical electrical and mechanical specifications while differing only in product lifecycle status (Not For New Designs) and the absence of anti-sulfur coating specification in its detailed description.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F2671U is the preferred selection for new designs due to its active product status and anti-sulfur coating specification, which provides enhanced reliability in corrosive environments. This part carries full manufacturer support and is recommended for long-term production applications.

The ERJ-14NF2671U is suitable as a substitute only when the primary part is unavailable or when design revisions permit use of legacy-qualified components. Its "Not For New Designs" status indicates that Panasonic has transitioned this part to mature lifecycle phase. Both parts maintain identical electrical performance, mechanical compatibility, and automotive qualification levels. Selection between these parts should be based on design phase (new vs. existing) and supply chain requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2671U be used as a direct replacement for ERJ-S14F2671U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, operate across the identical temperature range (-55°C ~ 155°C), and provide equivalent electrical performance with 2.67 kOhms ±1% resistance. The primary difference is product lifecycle status; ERJ-14NF2671U is designated "Not For New Designs."

Q: What is the significance of the anti-sulfur coating on the ERJ-S14F2671U?

A: The anti-sulfur feature on the ERJ-S14F2671U provides enhanced resistance to sulfur-containing environments, which can degrade resistor performance over time. The ERJ-14NF2671U does not specify this coating in its detailed description.

Q: Are both parts physically identical in package dimensions?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). They are mechanically interchangeable on PCBs.

Q: What does "Not For New Designs" mean for the ERJ-14NF2671U?

A: This designation indicates that Panasonic has classified this part as mature and is no longer recommending it for new product development. Existing designs using this part may continue in production, but new designs should specify the active ERJ-S14F2671U.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating they have no moisture sensitivity limitations and require no special handling or baking procedures prior to soldering.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications.
