ERJ-S1TF6341U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF6341U is a 6.34 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 918 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require components with equivalent electrical and mechanical characteristics. The ERJ-1TNF6341U represents a direct functional equivalent from the same manufacturer, though it carries a "Not For New Designs" status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF6341U is determined by strict equivalence across the following parameters:

• Resistance value: 6.34 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-1TNF6341U meets all electrical and mechanical substitution criteria. Additional cross-references (RC2512FK-076K34L, RMCF2512FT6K34, CRCW25126K34FKTG, CRCW25126K34FKEGHP, CRCW25126K34FKEG) are listed as secondary alternatives from the substitute part's documentation but require independent verification against the same parameter set.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S1TF6341U is the preferred selection for new designs due to its active production status and anti-sulfur coating feature. This part maintains full AEC-Q200 automotive qualification and ROHS3 compliance, making it suitable for automotive and industrial applications requiring high reliability.

The ERJ-1TNF6341U provides electrical and mechanical equivalence and is suitable for legacy system maintenance or design revisions where component replacement is necessary. However, its "Not For New Designs" status indicates that Panasonic has transitioned this series to the ERJ-S1T platform. The anti-sulfur feature present in the ERJ-S1TF6341U is absent from the ERJ-1TNF6341U, which may be a consideration for applications in corrosive environments.

Both parts share identical electrical specifications, package dimensions, and automotive certifications, ensuring direct functional interchangeability in circuit applications where the specified parameters are required.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF6341U be used as a direct replacement for ERJ-S1TF6341U?

A: Yes, the ERJ-1TNF6341U meets all electrical and mechanical substitution criteria. Both parts have identical resistance (6.34 kOhms), tolerance (±1%), power rating (1W), package (2512), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 qualification. The primary difference is product status and the anti-sulfur coating feature in the ERJ-S1TF6341U.

Q: What is the significance of the anti-sulfur coating in ERJ-S1TF6341U?

A: The anti-sulfur coating is a material feature that provides enhanced protection against sulfur-containing atmospheric contaminants. This feature is present in the ERJ-S1TF6341U but not listed in the ERJ-1TNF6341U specifications. For applications in environments with sulfur exposure, the ERJ-S1TF6341U is the specified choice.

Q: Are the package dimensions identical between these parts?

A: Yes. Both the ERJ-S1TF6341U and ERJ-1TNF6341U use the 2512 (6432 Metric) package with dimensions of 0.252" L x 0.126" W (6.40mm x 3.20mm) and maximum seated height of 0.028" (0.70mm). They are mechanically interchangeable on PCB layouts.

Q: What does "Not For New Designs" mean for the ERJ-1TNF6341U?

A: This status indicates that Panasonic has discontinued active development and promotion of the ERJ-1TNF6341U series for new product designs. The ERJ-S1T series (represented by ERJ-S1TF6341U) is the current recommended platform. Existing designs using ERJ-1TNF6341U may continue to source the part, but new designs should specify the ERJ-S1TF6341U.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the ERJ-S1TF6341U and ERJ-1TNF6341U are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
