ERJ-S14F2431U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F2431U is a 2.43 kOhms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This part features anti-sulfur coating and automotive AEC-Q200 qualification, designed for automotive and industrial applications requiring enhanced reliability in harsh environments. The part maintains Active product status with 696 units in current inventory.

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

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.43 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The identified substitute parts meet all electrical specifications and package requirements. Differences in features (anti-sulfur coating, moisture resistance) and product status do not affect functional interchangeability for applications where these specific enhancements are not contractually mandated.

Parameter Comparison

Engineering Selection Recommendations

ERJ-S14F2431U (Primary Selection): Active product status with anti-sulfur coating and AEC-Q200 automotive qualification. Recommended for new designs and applications requiring automotive-grade reliability.

ERJ-14NF2431U (Alternative): Panasonic equivalent with identical electrical and mechanical specifications. Product status is "Not For New Designs," indicating this part is in mature phase. Suitable for legacy system maintenance or high-volume applications where supply availability is prioritized. Highest current inventory (14836 units).

RC1210FR-072K43L (Alternative): YAGEO equivalent meeting all electrical and mechanical specifications with moisture-resistant coating. Active product status. Does not carry AEC-Q200 automotive rating. Suitable for industrial and commercial applications where automotive qualification is not required.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2431U be used in new automotive designs? A: ERJ-14NF2431U carries "Not For New Designs" status. For new automotive applications, ERJ-S14F2431U is the appropriate selection. ERJ-14NF2431U is suitable for production support of existing designs or non-automotive applications.

Q: What is the difference between anti-sulfur and moisture-resistant coatings? A: Anti-sulfur coating (ERJ-S14F2431U) protects against sulfur-containing atmospheric contaminants common in automotive environments. Moisture-resistant coating (RC1210FR-072K43L) provides protection against humidity and moisture ingress. Selection depends on environmental exposure requirements.

Q: Is RC1210FR-072K43L suitable for automotive applications? A: RC1210FR-072K43L meets all electrical and mechanical specifications but does not carry AEC-Q200 automotive qualification. It is suitable for industrial and commercial applications. For automotive applications requiring AEC-Q200 compliance, select ERJ-S14F2431U or ERJ-14NF2431U.

Q: Are all three parts pin-compatible? A: Yes. All three parts are 1210 (3225 Metric) package with 2 terminations, identical lead spacing, and compatible PCB footprints. Physical dimensions vary slightly (height: 0.70mm, 0.70mm, 0.60mm respectively) but remain within standard 1210 package tolerance.

Q: What is MSL 1 (Unlimited) rating? A: MSL 1 indicates Moisture Sensitivity Level 1, the lowest moisture sensitivity classification. These parts require no special moisture control during storage, handling, or assembly. "Unlimited" means shelf life is not restricted by moisture exposure.
