ERJ-S14F3092U Equivalent & Substitute Parts
Part Overview
The ERJ-S14F3092U is a 30.9 kOhms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package format. This component is rated for 0.5W power dissipation and meets AEC-Q200 automotive qualification standards with anti-sulfur protection. The part is currently in active production status with 675 units available in stock.
Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit selection from qualified alternatives that maintain electrical and mechanical compatibility within the same parameter envelope.

Engineering Selection Recommendations
The ERJ-S14F3092U is the preferred selection for new designs due to its active product status and ongoing manufacturer support. This part carries full AEC-Q200 automotive qualification with anti-sulfur protection, meeting current automotive reliability standards.
The ERJ-14NF3092U is electrically and mechanically equivalent and may be selected when the primary part is unavailable. However, this part carries a "Not For New Designs" status, indicating that Panasonic has transitioned this series to end-of-life. Selection of the ERJ-14NF3092U is appropriate only for sustaining production, legacy system support, or temporary supply mitigation when the ERJ-S14F3092U cannot be procured within required lead times.
Both parts maintain identical compliance certifications (ROHS3, REACH Unaffected, AEC-Q200) and are suitable for automotive applications requiring -55°C to 155°C operating temperature performance.
Frequently Asked Questions (FAQ)
Q: Can ERJ-14NF3092U be used as a direct replacement for ERJ-S14F3092U in new designs?
A: Electrically and mechanically, yes. However, the ERJ-14NF3092U carries "Not For New Designs" status. New designs should specify the ERJ-S14F3092U to ensure long-term supply availability and manufacturer support.
Q: Are there any dimensional differences between these parts?
A: No. Both parts use the 1210 (3225 Metric) package with identical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm).
Q: Do both parts meet automotive qualification requirements?
A: Yes. Both the ERJ-S14F3092U and ERJ-14NF3092U carry AEC-Q200 automotive qualification and are suitable for automotive applications.
Q: What is the difference between the ERJ-S14 and ERJ-14N series designations?
A: The series designation reflects Panasonic's product line evolution. The ERJ-S14 series represents the current generation with active production status. The ERJ-14N series is a predecessor generation transitioned to end-of-life status.
Q: Are moisture sensitivity levels identical?
A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
Q: Can these parts be used interchangeably in PCB assembly?
A: Yes. Identical package format, termination count, and dimensions ensure direct PCB footprint compatibility without layout modifications.
