ERJ-S08F4751V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F4751V is a 4.75 kOhms ±1% 0.25W (1/4W) chip resistor in 1206 (3216 Metric) package manufactured by Panasonic Electronic Components. This thick film resistor features anti-sulfur coating and automotive AEC-Q200 qualification, designed for automotive and industrial applications requiring high reliability in harsh environments. The part is currently active in production with 986 units in stock. Equivalent and substitute parts are necessary to ensure design flexibility, manage supply chain continuity, and accommodate different procurement channels or manufacturing preferences while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S08F4751V is determined by strict equivalence across the following critical parameters:

Resistance value: 4.75 kOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Package: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Moisture sensitivity level: 1 (Unlimited)

All listed substitute parts meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) within the 1206 package specification, manufacturing features (anti-sulfur vs. moisture resistant), and product status do not affect functional substitutability. One substitute part (CRCW12064K75FKEAHP) features a higher power rating (0.75W) and is listed as a functional upgrade option where increased power dissipation capability is beneficial.

Engineering Selection Recommendations

For new designs and production applications, prioritize active product status parts with full ROHS3 compliance and AEC-Q200 automotive qualification. The following parts are recommended as primary substitutes:

CRCW12064K75FKEA (Vishay Dale), RMCF1206FT4K75 (Stackpole Electronics Inc), and AC1206FR-074K75L (YAGEO) are all active, ROHS3 compliant, and AEC-Q200 qualified, providing direct functional equivalence to the ERJ-S08F4751V.

CRCW12064K75FKEAHP (Vishay Dale) is suitable where increased power dissipation (0.75W vs. 0.25W) provides design margin or thermal performance benefits, while maintaining all other electrical and compliance specifications.

ERJ-8ENF4751V (Panasonic) is electrically equivalent but marked as "Not For New Designs," making it suitable only for legacy system maintenance or existing production continuity where design changes are not feasible.

CRCW12064K75FKTA (Vishay Dale) is not recommended due to RoHS non-compliance and REACH affected status, unless legacy system requirements explicitly permit non-compliant components.

CR1206-FX-4751ELF (Bourns Inc.) and RC1206FR-074K75L (YAGEO) lack AEC-Q200 automotive qualification and are suitable only for non-automotive applications where automotive-grade reliability is not required.

Frequently Asked Questions (FAQ)

Q: Can ERJ-S08F4751V be directly replaced with any of the listed substitute parts?

A: Yes, all listed parts are electrically and mechanically equivalent within the 1206 package specification. Direct PCB footprint compatibility is maintained. However, product status and compliance certifications should be evaluated against your application requirements.

Q: What is the difference between ERJ-S08F4751V and ERJ-8ENF4751V?

A: Both parts are manufactured by Panasonic with identical electrical specifications (4.75 kOhms ±1%, 0.25W, AEC-Q200). The primary difference is product status: ERJ-S08F4751V is active in production, while ERJ-8ENF4751V is marked "Not For New Designs." For new designs, use ERJ-S08F4751V or equivalent active parts.

Q: Why is CRCW12064K75FKEAHP listed as a substitute if it has 0.75W power rating instead of 0.25W?

A: CRCW12064K75FKEAHP is a functional upgrade option. Higher power rating does not prevent substitution; it provides additional thermal margin. This part is suitable where increased power dissipation capability is beneficial or where design margins require higher rated components.

Q: Are there differences in physical dimensions between substitute parts?

A: Yes. While all parts conform to the 1206 (3216 Metric) package standard, individual manufacturers specify slightly different maximum dimensions. Typical variations: length 0.122" to 0.126" (3.10mm to 3.20mm), height 0.024" to 0.030" (0.60mm to 0.75mm). These variations remain within 1206 package tolerance and do not affect PCB footprint compatibility.

Q: Which substitute parts are suitable for automotive applications?

A: Parts with AEC-Q200 qualification are suitable for automotive use: ERJ-8ENF4751V, AC1206FR-074K75L, CRCW12064K75FKEA, CRCW12064K75FKEAHP, RMCF1206FG4K75, and RMCF1206FT4K75. CR1206-FX-4751ELF and RC1206FR-074K75L lack AEC-Q200 qualification and are not recommended for automotive applications.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All recommended substitute parts are ROHS3 compliant except CRCW12064K75FKTA.

Q: Can I use CR1206-FX-4751ELF or RC1206FR-074K75L in place of ERJ-S08F4751V?

A: Electrically and mechanically, yes. However, these parts lack AEC-Q200 automotive qualification. Use only if your application does not require automotive-grade reliability or if non-automotive use is confirmed.
