ERJ-S1TF2671U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF2671U is a 2.67 kOhms ±1% 1W chip resistor in 2512 (6432 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 harsh environments. The part is currently in active production status with 785 units available in stock.

Substitute parts become necessary when the primary part faces supply constraints, extended lead times, or when design flexibility permits component sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF2671U is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.67 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria. Dimensional variations within supplier tolerances do not affect functional compatibility in standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: ERJ-S1TF2671U

The ERJ-S1TF2671U maintains active production status and includes anti-sulfur coating, making it the preferred choice for new designs and applications requiring extended component lifecycle support.

Secondary Selection: AC2512FK-072K67L

The AC2512FK-072K67L from YAGEO is electrically and mechanically equivalent with active product status. This part includes moisture-resistant coating and represents a viable alternative when Panasonic supply is constrained. Both parts carry identical electrical specifications and automotive qualification.

Tertiary Selection: ERJ-1TNF2671U

The ERJ-1TNF2671U is electrically equivalent but carries "Not For New Designs" status. This part should be used only in legacy system maintenance or when existing inventory must be consumed. No new designs should incorporate this part number.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF2671U be used in new product designs?

A: No. ERJ-1TNF2671U carries "Not For New Designs" status. Use ERJ-S1TF2671U or AC2512FK-072K67L for new designs.

Q: Are dimensional differences between ERJ-S1TF2671U and AC2512FK-072K67L significant?

A: No. The dimensional variations (ERJ-S1TF2671U: 6.40mm x 3.20mm vs. AC2512FK-072K67L: 6.35mm x 3.10mm) fall within standard PCB assembly tolerances and do not affect footprint compatibility or electrical performance.

Q: Do all three parts meet automotive qualification requirements?

A: Yes. All three parts carry AEC-Q200 automotive qualification and ROHS3 compliance, suitable for automotive and industrial applications.

Q: What is the difference between anti-sulfur and moisture-resistant coatings?

A: Anti-sulfur coating (ERJ-S1TF2671U) protects against sulfur-containing atmospheric contaminants. Moisture-resistant coating (AC2512FK-072K67L) provides protection against humidity and moisture ingress. Both coatings serve different environmental protection purposes; selection depends on application environment.

Q: Can these parts be used interchangeably on existing PCBs?

A: Yes. All three parts share identical 2512 package footprints and electrical specifications. PCB layout modifications are not required for substitution.
