ERJ-S14F7872U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F7872U is a 78.7 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 is designed for automotive applications with AEC-Q200 qualification and anti-sulfur protection. The part is currently in active production status with 1015 units available in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design requirements permit use of functionally equivalent alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F7872U is determined by strict equivalence across the following critical parameters:

• Resistance value: 78.7 kOhms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package format: 1210 (3225 Metric)
• Composition: Thick film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• Termination count: 2
• Physical dimensions: 3.20mm × 2.50mm footprint

The ERJ-14NF7872U meets all electrical and mechanical parameters required for direct substitution. However, product status and compliance certifications differ and must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F7872U is the preferred selection for new designs due to its active product status and RoHS3 compliance. This part meets current regulatory requirements and benefits from ongoing manufacturer support.

The ERJ-14NF7872U is electrically and mechanically equivalent but carries a "Not For New Designs" status and does not meet RoHS3 compliance. This substitute is suitable only for legacy system maintenance, repair operations, or applications where RoHS compliance is not required. The higher available inventory (4372 units) may provide supply chain advantages for high-volume legacy production support.

Selection between these parts must account for regulatory compliance requirements, product lifecycle stage, and supply chain constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF7872U be used as a direct replacement for ERJ-S14F7872U in new designs?

A: No. While the parts are electrically and mechanically equivalent, the ERJ-14NF7872U carries a "Not For New Designs" status and does not meet RoHS3 compliance. New designs must use the ERJ-S14F7872U.

Q: What are the key differences between these two parts?

A: The primary differences are product lifecycle status and regulatory compliance. The ERJ-S14F7872U is active production with RoHS3 compliance and anti-sulfur protection. The ERJ-14NF7872U is not recommended for new designs and is RoHS non-compliant. All electrical parameters, power ratings, temperature coefficients, and package dimensions are identical.

Q: Are the physical footprints identical?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical dimensions of 3.20mm length × 2.50mm width × 0.70mm maximum height. PCB layout and reflow profiles are interchangeable.

Q: What does "Not For New Designs" mean?

A: This designation indicates the part is in mature or end-of-life phase. Panasonic continues to support existing inventory but does not recommend this part for new product development. The ERJ-S14F7872U should be used for all new designs.

Q: Are both parts suitable for automotive applications?

A: Both parts carry AEC-Q200 automotive qualification and operate across the -55°C to 155°C temperature range required for automotive use. However, only the ERJ-S14F7872U includes anti-sulfur protection and meets current compliance standards for new automotive designs.

Q: What is the significance of RoHS3 compliance?

A: RoHS3 compliance indicates the part meets current European Union Restriction of Hazardous Substances regulations. The ERJ-S14F7872U meets this requirement; the ERJ-14NF7872U does not. For applications subject to RoHS requirements or for export to regulated markets, the ERJ-S14F7872U is mandatory.
