Equivalent & Substitute Parts for ERJ-S1TF3483U

Part Overview

The ERJ-S1TF3483U is a 348 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 966 pieces available in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design revisions require alternative qualified sources, or when supply chain optimization requires multi-source qualification.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF3483U is determined by strict equivalence across the following parameters:

• Resistance value: 348 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)

Two substitute parts meet all substitution criteria: ERJ-1TNF3483U (Panasonic Electronic Components) and CRCW2512348KFKEG (Vishay Dale). Both parts are electrically and mechanically equivalent to the main part number.

Parameter Comparison

Engineering Selection Recommendations

For new designs, the ERJ-S1TF3483U (Panasonic, Active status) is the primary selection. The CRCW2512348KFKEG (Vishay Dale, Active status) is a qualified alternative source that maintains full electrical and mechanical equivalence with identical compliance certifications.

The ERJ-1TNF3483U (Panasonic, Not For New Designs status) is suitable only for legacy design support, maintenance, or replacement of existing assemblies. This part should not be selected for new product development.

All three parts carry identical AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating, confirming their interchangeability within the specified electrical and thermal operating parameters.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF3483U be used in new designs? A: No. ERJ-1TNF3483U carries "Not For New Designs" status. For new product development, use ERJ-S1TF3483U or CRCW2512348KFKEG.

Q: Are the physical dimensions identical across all three parts? A: The ERJ-S1TF3483U and ERJ-1TNF3483U have identical dimensions (0.252" L x 0.126" W / 6.40mm x 3.20mm). The CRCW2512348KFKEG has slightly different dimensions (0.248" L x 0.124" W / 6.30mm x 3.15mm). All three fit the 2512 package footprint with maximum seated height of 0.028" (0.70mm).

Q: What is the difference between ERJ-S1TF3483U and ERJ-1TNF3483U? A: Both parts are electrically identical with matching resistance, tolerance, power rating, and temperature specifications. The primary difference is product status: ERJ-S1TF3483U is Active (recommended for new designs), while ERJ-1TNF3483U is Not For New Designs (legacy support only). ERJ-S1TF3483U includes anti-sulfur coating as an additional feature.

Q: Are all substitute parts AEC-Q200 qualified? A: Yes. All three parts carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring this certification.

Q: Can these parts be used interchangeably on existing PCBs? A: Yes, within the constraints of physical dimensions. The ERJ-S1TF3483U and ERJ-1TNF3483U are fully interchangeable. The CRCW2512348KFKEG has slightly smaller dimensions but remains compatible with standard 2512 footprints.
