ERJ-S14F2373U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F2373U is a 237 kOhms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This component 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 993 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life, experiences supply constraints, or when design flexibility is required for multi-source component strategies in production environments.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2373U is determined by strict equivalence across the following critical parameters:

• Resistance value: 237 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Package: 1210 (3225 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)

The ERJ-14NF2373U meets all substitution criteria and is listed as an approved equivalent part.

Engineering Selection Recommendations

The ERJ-S14F2373U is the recommended primary selection for new designs due to its active production status. The ERJ-14NF2373U is electrically and mechanically equivalent and maintains full compliance with AEC-Q200 automotive qualification and ROHS3 requirements. However, the ERJ-14NF2373U carries a "Not For New Designs" status, making it suitable only for replacement, repair, or legacy system applications where the original part specification must be maintained.

For production environments requiring multi-source qualification, both parts satisfy identical electrical and mechanical parameters. Selection between them should be based on design phase (new vs. legacy) and supply chain strategy.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2373U be used as a direct replacement for ERJ-S14F2373U in new designs?

A: Electrically and mechanically, yes. However, the ERJ-14NF2373U carries "Not For New Designs" status. New designs should specify the ERJ-S14F2373U to ensure long-term supply continuity and manufacturer support.

Q: Are there any differences in automotive qualification between these parts?

A: Both parts carry identical AEC-Q200 automotive qualification and meet the same operating temperature range (-55°C ~ 155°C). No qualification differences exist.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts are packaged in 1210 (3225 Metric) 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: What is the difference between ERJ-S14 and ERJ-14N series designations?

A: The series designation reflects different product generations within Panasonic's resistor portfolio. The ERJ-S14F2373U (ERJ-S14 series) is the current active product, while ERJ-14NF2373U (ERJ-14N series) is a legacy product line no longer recommended for new designs.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
