ERJ-S1TF6813U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF6813U is a 681 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. Substitute parts may be required due to inventory constraints, supply chain discontinuation of legacy series, or design migration to newer component families while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the ERJ-S1TF6813U is permissible with parts meeting the following criteria:

• Resistance value: 681 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 (Unlimited)

The ERJ-1TNF6813U qualifies as a direct substitute, sharing identical electrical specifications and package dimensions. The primary distinction is series designation (ERJ-1TN versus ERJ-S1T) and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S1TF6813U is the preferred selection for new designs due to its active production status. The ERJ-1TNF6813U provides electrical and mechanical equivalence and is suitable for replacement applications, legacy system maintenance, or inventory supplementation. However, the ERJ-1TNF6813U carries a "Not For New Designs" classification, indicating that Panasonic has transitioned this series to mature or end-of-life status. For new product development, the ERJ-S1TF6813U series should be specified to ensure long-term supply continuity and manufacturer support.

Both parts satisfy identical compliance requirements: AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1). Thermal and electrical performance characteristics are equivalent across the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF6813U be used as a direct replacement for ERJ-S1TF6813U in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance, tolerance, power rating, package dimensions, and thermal characteristics. The ERJ-1TNF6813U is a valid substitute for repair, rework, or inventory replenishment of existing products.

Q: Why is ERJ-1TNF6813U marked "Not For New Designs"?

A: This designation indicates that Panasonic has classified the ERJ-1TN series as mature or transitional. New product designs should specify the ERJ-S1TF6813U series to ensure alignment with current manufacturing roadmaps and sustained supply availability.

Q: Are there any differences in anti-sulfur coating between these parts?

A: The ERJ-S1TF6813U explicitly includes anti-sulfur coating in its feature set. The ERJ-1TNF6813U specification does not list this feature. For applications requiring anti-sulfur protection, the ERJ-S1TF6813U is the appropriate selection.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the ERJ-S1TF6813U and ERJ-1TNF6813U carry AEC-Q200 automotive qualification and are suitable for automotive applications within the specified operating temperature range of -55°C to 155°C.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 2512 (6432 Metric) package with identical dimensions: 0.252" L × 0.126" W (6.40mm × 3.20mm) and maximum seated height of 0.028" (0.70mm). PCB footprints and assembly processes are interchangeable.
