ERJ-S14F2872U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F2872U is a 28.7 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 862 units available in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require components from alternative product lines that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2872U is determined by strict equivalence across the following parameters:

• Resistance value: 28.7 kOhms
• Tolerance: ±1%
• Power rating: 0.5W
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• Termination count: 2
• RoHS and environmental compliance status

The ERJ-14NF2872U qualifies as a direct substitute based on matching all electrical specifications and package requirements. Differences in product status and series designation do not affect functional compatibility in applications where the ERJ-S14F2872U is currently deployed.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F2872U is the preferred selection for new designs due to its active product status. The ERJ-14NF2872U is electrically and mechanically equivalent and suitable for replacement applications where the primary part is unavailable or discontinued.

The ERJ-14NF2872U carries a "Not For New Designs" status, indicating Panasonic has transitioned this series to the ERJ-S14 line. However, both parts maintain identical electrical performance, package compatibility, and automotive qualification standards. Selection between these parts should be based on design phase requirements and inventory availability rather than functional differences.

Both parts comply with ROHS3 and REACH requirements, carry AEC-Q200 automotive certification, and feature unlimited moisture sensitivity rating for standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2872U be used as a direct replacement for ERJ-S14F2872U in existing assemblies?

A: Yes. Both parts are electrically identical with matching resistance, tolerance, power rating, temperature coefficient, and operating range. The 1210 package dimensions and termination configuration are identical, enabling direct PCB substitution without layout modifications.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF2872U?

A: This designation indicates Panasonic has discontinued the ERJ-14N series for new product development. The ERJ-S14 series is the current production line. Existing designs using ERJ-14NF2872U can continue production, but new designs should specify ERJ-S14F2872U to ensure long-term supply continuity.

Q: Are there any differences in anti-sulfur protection between these parts?

A: The ERJ-S14F2872U explicitly includes anti-sulfur protection in its specification. The ERJ-14NF2872U specification does not list this feature. For applications requiring sulfur resistance, the ERJ-S14F2872U is the specified choice.

Q: Do both parts meet the same automotive qualification standards?

A: Yes. Both parts carry AEC-Q200 certification, meeting automotive-grade reliability and performance requirements for temperature cycling, moisture resistance, and failure rate specifications.

Q: What are the physical dimensions, and are they identical?

A: Both parts measure 0.126" L × 0.098" W (3.20mm × 2.50mm) with a maximum seated height of 0.028" (0.70mm). The 1210 package format is identical, ensuring compatibility with existing PCB footprints.
