ERJ-S1TF2672U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF2672U is a 26.7 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 automotive and industrial environments. The part is currently in active production status with 972 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives that maintain identical electrical and mechanical performance within the same package specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF2672U is determined by strict equivalence across the following critical parameters:

• Resistance value: 26.7 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 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-1TNF2672U qualifies as a direct substitute, meeting all electrical and mechanical specifications. This part differs only in series designation (ERJ-1TN versus ERJ-S1T) and product status classification, with no impact on functional performance or reliability characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S1TF2672U is the preferred selection for new designs due to its active product status and ongoing manufacturer support. The ERJ-1TNF2672U provides functional equivalence and maintains full compliance with automotive and environmental standards, making it suitable for applications where supply of the primary part is constrained.

Selection between these parts should be based on availability and procurement timeline requirements. Both parts deliver identical electrical performance, thermal characteristics, and reliability ratings. The "Not For New Designs" status of the ERJ-1TNF2672U indicates manufacturer preference for the ERJ-S1TF2672U in future applications, though the substitute remains fully qualified for existing designs and production environments.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF2672U be used as a direct replacement for ERJ-S1TF2672U?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance, tolerance, power rating, package dimensions, and automotive qualifications. The difference in series designation does not affect performance or compatibility.

Q: What is the significance of the "Not For New Designs" status on the ERJ-1TNF2672U?

A: This classification indicates the manufacturer recommends the ERJ-S1TF2672U for new product development. However, the ERJ-1TNF2672U remains fully functional and qualified for all applications where the main part is specified.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 2512 (6432 Metric) package with identical length (0.252" / 6.40mm), width (0.126" / 3.20mm), and maximum seated height (0.028" / 0.70mm).

Q: Do both parts meet automotive reliability standards?

A: Yes. Both the ERJ-S1TF2672U and ERJ-1TNF2672U carry AEC-Q200 qualification and operate across the identical temperature range of -55°C to 155°C.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1) ratings.
