ERJ-S1TF1150U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF1150U is a 115 Ohms ±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 1034 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same package footprint and performance specifications. Alternative sources become necessary for supply chain continuity, design flexibility, or when the primary part reaches end-of-life status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF1150U is determined by strict equivalence across the following parameters:

• Resistance value: 115 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package footprint: 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

Two substitute parts meet these criteria: ERJ-1TNF1150U (Panasonic) and CRCW2512115RFKEG (Vishay Dale). Both maintain identical electrical specifications and package dimensions within acceptable tolerances, enabling direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

ERJ-S1TF1150U (Primary Selection): Recommended for new designs. Active production status ensures long-term availability and supply chain stability. Anti-sulfur coating provides enhanced environmental protection. Current inventory supports immediate procurement.

CRCW2512115RFKEG (Preferred Substitute): Active production status from Vishay Dale provides equivalent performance and compliance. Suitable for designs requiring multi-source qualification or when Panasonic supply is constrained. Dimensions are within acceptable tolerance (6.30mm x 3.15mm vs. 6.40mm x 3.20mm).

ERJ-1TNF1150U (Legacy Substitute): Marked "Not For New Designs" by manufacturer. Use only for legacy system maintenance or when existing designs are locked to this part number. High inventory availability (8681 units) may support extended production runs of existing products.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF1150U be used in new designs? A: No. This part is designated "Not For New Designs" by Panasonic. Use ERJ-S1TF1150U or CRCW2512115RFKEG for new applications.

Q: Are the physical dimensions identical across all three parts? A: Dimensions are equivalent within manufacturing tolerance. ERJ-S1TF1150U and ERJ-1TNF1150U are 6.40mm x 3.20mm. CRCW2512115RFKEG is 6.30mm x 3.15mm. All fit the 2512 package footprint and are PCB-compatible.
