ERJ-S1TF3090U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF3090U is a 309 Ohms ±1% 1W thick film chip resistor in 2512 (6432 Metric) package manufactured by Panasonic Electronic Components. This component features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for demanding automotive and industrial applications. The part is currently in active production status with 788 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design flexibility is required across multiple suppliers, or when production volumes demand alternative sourcing options while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF3090U is determined by strict equivalence across the following critical parameters:

• Resistance value: 309 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitute parts meet these core electrical and mechanical requirements. Variations in specific features (such as anti-sulfur coating or automotive certification) are noted in the comparison table but do not prevent functional substitution when the above parameters are matched.

Parameter Comparison

Engineering Selection Recommendations

ERJ-S1TF3090U (Primary Part): Recommended for new designs and applications requiring anti-sulfur coating with automotive AEC-Q200 qualification. Active production status ensures long-term availability.

ERJ-1TNF3090U (Panasonic Alternative): Functionally equivalent with identical electrical specifications and automotive AEC-Q200 rating. Marked as "Not For New Designs," indicating this part is in mature or declining production phase. Higher inventory availability (5918 units) may support short-term sourcing needs. Suitable for legacy design updates or high-volume production requiring alternative Panasonic sourcing.

RC2512FK-07309RL (YAGEO Alternative): Meets all core electrical and mechanical requirements with active production status. Features moisture-resistant coating instead of anti-sulfur treatment. Highest inventory availability (9004 units) supports supply chain flexibility. Suitable for applications where multi-source qualification is required or when Panasonic parts face supply constraints.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF3090U be used as a direct replacement for ERJ-S1TF3090U?

A: Yes. Both parts share identical electrical specifications (309 Ohms ±1%, 1W, ±100ppm/°C, -55°C ~ 155°C), package format (2512), and automotive AEC-Q200 certification. The primary difference is product status; ERJ-1TNF3090U is marked "
