ERJ-S08F3093V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F3093V is a 309 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Panasonic Electronic Components. This part features anti-sulfur coating and automotive AEC-Q200 qualification, designed for applications requiring high reliability in harsh environments. The product is currently active and available in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift toward alternative manufacturers, or when specific feature sets (such as moisture resistance or different automotive certifications) better suit application needs.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S08F3093V is determined by strict equivalence across the following parameters:

Resistance value: 309 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)
RoHS compliance: ROHS3 Compliant

All substitute parts listed meet these core electrical and mechanical specifications. Variations in secondary features (such as anti-sulfur coating versus moisture resistance, or automotive AEC-Q200 certification) do not disqualify substitution but indicate design-specific considerations.

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the ERJ-S08F3093V. Selection among alternatives should be based on the following criteria:

For Active Product Status: CR1206-FX-3093ELF (Bourns), CRCW1206309KFKEA (Vishay Dale), RC1206FR-07309KL (YAGEO), and RMCF1206FT309K (Stackpole Electronics Inc) are all currently active products suitable for new designs.

For Automotive AEC-Q200 Compliance: CRCW1206309KFKEA, RMCF1206FT309K, and ERJ-8ENF3093V maintain automotive qualification equivalent to the primary part.

For Moisture Resistance: CR1206-FX-3093ELF and RC1206FR-07309KL provide moisture-resistant thick film construction as an alternative to anti-sulfur coating.

For Supply Availability: RC1206FR-07309KL (YAGEO) offers the highest inventory level at 133,118 pieces. ERJ-8ENF3093V (Panasonic) provides 51,488 pieces but is marked "Not For New Designs."

For Anti-Sulfur Specification: Only ERJ-S08F3093V includes explicit anti-sulfur coating. If this feature is mandatory, no direct substitute exists; alternative moisture-resistant or standard thick film options must be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF3093V replace ERJ-S08F3093V in new designs?

A: ERJ-8ENF3093V is electrically and mechanically equivalent but carries a "Not For New Designs" status. It is suitable only for legacy product support or maintenance applications. For new designs, use active alternatives such as CRCW1206309KFKEA, RMCF1206FT309K, or RC1206FR-07309KL.

Q: What is the difference between anti-sulfur and moisture-resistant coatings?

A: Anti-sulfur coating protects against sulfur-containing atmospheric contaminants. Moisture-resistant coating protects against humidity and moisture ingress. Both are protective measures; the choice depends on the specific environmental exposure of the application.

Q: Are all substitute parts AEC-Q200 qualified?

A: No. CR1206-FX-3093ELF and RC1206FR-07309KL do not carry AEC-Q200 certification. If automotive qualification is required, select from CRCW1206309KFKEA, RMCF1206FT309K, or ERJ-8ENF3093V.

Q: Do package dimensions vary among substitutes?

A: All parts use 1206 (3216 Metric) package. Minor variations exist in maximum seated height: ERJ-S08F3093V and RMCF1206FT309K are 0.028" (0.70mm), CRCW1206309KFKEA is 0.024" (0.60mm), CR1206-FX-3093ELF is 0.030" (0.75mm), and RC1206FR-07309KL is 0.026" (0.65mm). These differences are within standard PCB assembly tolerances.

Q: Which substitute offers the best supply availability?

A: RC1206FR-07309KL (YAGEO) has the highest inventory at 133,118 pieces, followed by ERJ-8ENF3093V at 51,488 pieces.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.
