ERJ-S14F2493U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F2493U is a 249 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 829 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift to alternative manufacturers, or when inventory constraints require sourcing from alternative qualified suppliers while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2493U is determined by strict equivalence across the following parameters:

• Resistance value: 249 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)

Two substitute parts meet all substitution criteria: ERJ-14NF2493U (Panasonic Electronic Components) and CRCW1210249KFKEA (Vishay Dale).

Parameter Comparison

Engineering Selection Recommendations

For new designs, CRCW1210249KFKEA (Vishay Dale) is the preferred substitute. This part carries active product status, maintains full AEC-Q200 automotive qualification, and ROHS3 compliance. The seated height of 0.024" (0.60mm) is within acceptable tolerance for 1210 package footprints and does not impact PCB layout or assembly processes.

ERJ-14NF2493U (Panasonic Electronic Components) is electrically and mechanically equivalent but carries "Not For New Designs" status. This part is suitable only for replacement or repair of existing assemblies where the original part number must be maintained or where design revision is not feasible.

Both substitute parts are qualified to the same AEC-Q200 automotive standard and maintain identical electrical performance across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2493U be used in new product designs? A: ERJ-14NF2493U carries "Not For New Designs" product status. For new designs, use CRCW1210249KFKEA or the primary part ERJ-S14F2493U.

Q: Are there dimensional differences between the substitute parts? A: The seated height differs slightly: ERJ-S14F2493U and ERJ-14NF2493U are 0.028" (0.70mm) maximum, while CRCW1210249KFKEA is 0.024" (0.60mm) maximum. Both are within 1210 package specifications and do not affect PCB layout or assembly compatibility.

Q: Do all parts meet automotive qualification requirements? A: Yes. All three parts—ERJ-S14F2493U, ERJ-14NF2493U, and CRCW1210249KFKEA—are AEC-Q200 qualified and suitable for automotive applications.

Q: What is the difference between ERJ-S14 and ERJ-14N series? A: Both are Panasonic thick film chip resistors with identical electrical specifications. ERJ-S14 is the current active series; ERJ-14N is the legacy series marked "Not For New Designs."

Q: Are all substitute parts RoHS3 compliant? A: Yes. ERJ-S14F2493U, ERJ-14NF2493U, and CRCW1210249KFKEA are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Can I interchange these parts on the same PCB assembly? A: Yes. All three parts are mechanically and electrically equivalent within the specified parameters. The 1210 package footprint accommodates all variants without modification.
