ERJ-S14F2430U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F2430U is a 243 Ohm ±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 1035 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2430U is determined by strict equivalence across the following critical parameters:

• Resistance value: 243 Ohms
• Tolerance: ±1%
• Power rating: 0.5W
• Package: 1210 (3225 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

The ERJ-14NF2430U qualifies as a direct substitute, meeting all electrical and mechanical parameters. The primary distinction is product status: ERJ-S14F2430U is active production, while ERJ-14NF2430U is designated "Not For New Designs," indicating it remains available but is not recommended for new circuit designs.

Parameter Comparison

Engineering Selection Recommendations

For new circuit designs, the ERJ-S14F2430U is the preferred selection due to its active production status and manufacturer commitment to continued supply. This part carries full automotive AEC-Q200 qualification and ROHS3 compliance, meeting current regulatory requirements.

The ERJ-14NF2430U remains electrically and mechanically equivalent and maintains all required certifications. However, its "Not For New Designs" status indicates the manufacturer is transitioning away from this product line. Selection of ERJ-14NF2430U is appropriate only for legacy system maintenance, repair, or when supply of the primary part is unavailable and design freeze permits substitution.

Both parts are manufactured by Panasonic Electronic Components and share identical electrical performance, thermal characteristics, and reliability ratings. The choice between them should be driven by supply availability and design phase requirements rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2430U be used as a direct replacement for ERJ-S14F2430U in new designs?

A: Electrically and mechanically, yes. However, the ERJ-14NF2430U carries a "Not For New Designs" designation. New designs should specify ERJ-S14F2430U to ensure long-term supply continuity and manufacturer support.

Q: Are there any differences in reliability or performance between these two parts?

A: No. Both parts meet identical AEC-Q200 automotive qualification standards, operate across the same temperature range (-55°C ~ 155°C), and maintain ±100ppm/°C temperature coefficient. Reliability ratings and performance characteristics are equivalent.

Q: What does "Not For New Designs" mean for the ERJ-14NF2430U?

A: This status indicates the manufacturer is phasing out this product line. While the part remains available and functional, Panasonic recommends using ERJ-S14F2430U for new circuit designs to avoid potential future supply discontinuation.

Q: Are both parts RoHS compliant?

A: Yes. Both ERJ-S14F2430U and ERJ-14NF2430U are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard PCB assembly processes.

Q: Can these parts be used interchangeably on the same PCB assembly line?

A: Yes. Both parts share identical 1210 (3225 Metric) package dimensions (0.126" L x 0.098" W, 0.028" max height), termination count (2), and tape & reel packaging format. No design or assembly modifications are required for substitution.
