ERJ-S14F4872U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F4872U is a 48.7 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 qualified to the AEC-Q200 automotive standard with anti-sulfur protection. The part is currently in active production status with 706 units available in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design revisions require alternative qualified sources, or when inventory constraints require sourcing from alternative manufacturers while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F4872U is determined by strict equivalence across the following parameters:

• Resistance value: 48.7 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Package format: 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)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed meet the electrical and mechanical substitution criteria for the ERJ-S14F4872U. Selection should be based on the following factors:

For new designs and active production programs, the ERJ-S14F4872U (primary part) and CRCW121048K7FKEA are both qualified for use, as both maintain active product status. The ERJ-S14F4872U includes anti-sulfur protection as an additional feature.

The ERJ-14NF4872U is marked as "Not For New Designs" and should be used only for legacy system support, field replacements, or existing production continuity where design changes are not feasible.

All parts carry identical AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating, confirming suitability for automotive applications across the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF4872U be used as a direct replacement for ERJ-S14F4872U in new designs?

A: No. The ERJ-14NF4872U carries a "Not For New Designs" status. For new designs, use either the ERJ-S14F4872U or CRCW121048K7FKEA, both of which are in active production.

Q: Are there any physical dimension differences between these parts?

A: All three parts use the 1210 (3225 Metric) package. The ERJ-S14F4872U and ERJ-14NF4872U have a maximum seated height of 0.028" (0.70mm), while the CRCW121048K7FKEA has a maximum seated height of 0.024" (0.60mm). This minor difference does not affect PCB layout compatibility for standard 1210 footprints.

Q: Do all substitute parts meet automotive qualification requirements?

A: Yes. All three parts are qualified to AEC-Q200 and are suitable for automotive applications within the -55°C to 155°C operating temperature range.

Q: What is the difference between ERJ-S14F4872U and ERJ-14NF4872U?

A: Both parts are Panasonic products with identical electrical specifications. The primary difference is that ERJ-S14F4872U includes anti-sulfur protection and maintains active product status, while ERJ-14NF4872U is designated "Not For New Designs."

Q: Can CRCW121048K7FKEA be used interchangeably with Panasonic parts?

A: Yes. The CRCW121048K7FKEA from Vishay Dale meets all electrical and mechanical parameters required for substitution. It is manufactured by a different supplier but carries identical specifications, ratings, and compliance certifications.
