ERJ-S1TF1371U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF1371U is a 1.37 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 715 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility is required for multi-source component strategies in production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF1371U is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.37 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-1TNF1371U meets all electrical and mechanical parameters required for direct substitution. This part differs only in product status (Not For New Designs) and the absence of anti-sulfur coating specification in its detailed description, though it maintains identical electrical performance and package specifications.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S1TF1371U is the preferred selection for new designs due to its active production status and anti-sulfur coating feature, which provides enhanced reliability in corrosive environments. The ERJ-1TNF1371U is electrically and mechanically equivalent and maintains full AEC-Q200 automotive qualification and ROHS3 compliance, making it suitable for applications where supply of the primary part is constrained. However, the ERJ-1TNF1371U carries a "Not For New Designs" designation, indicating it is in legacy status. Selection between these parts should be based on availability requirements and design phase considerations rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF1371U be used as a direct replacement for ERJ-S1TF1371U in automotive applications?

A: Yes. Both parts meet identical electrical specifications (1.37 kOhms ±1%, 1W), operate across the same temperature range (-55°C ~ 155°C), carry AEC-Q200 automotive qualification, and use the same 2512 package. The primary difference is product status; ERJ-1TNF1371U is not recommended for new designs.

Q: What is the significance of the anti-sulfur coating on the ERJ-S1TF1371U?

A: Anti-sulfur coating is specified only for the ERJ-S1TF1371U in the provided data. This feature enhances reliability in environments with sulfur-containing contaminants. The ERJ-1TNF1371U does not list this feature in its specification.

Q: Are both parts suitable for high-temperature automotive applications?

A: Yes. Both parts operate across -55°C ~ 155°C and maintain ±100ppm/°C temperature coefficient, meeting automotive thermal requirements. Both carry AEC-Q200 qualification.

Q: What is the difference between the ERJ-S1T and ERJ-1TN series?

A: These are different product series from Panasonic. The ERJ-S1T series (represented by ERJ-S1TF1371U) is in active production. The ERJ-1TN series (represented by ERJ-1TNF1371U) is in legacy status with "Not For New Designs" designation.

Q: Are both parts RoHS compliant?

A: Yes. Both ERJ-S1TF1371U and ERJ-1TNF1371U are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
