ERJ-S08F3480V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F3480V is a 348 Ohm ±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 1004 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements shift toward alternative feature sets (such as higher power ratings or different environmental certifications), or when supply chain optimization requires sourcing from multiple qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S08F3480V is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Resistance value: 348 Ohms
• Tolerance: ±1%
• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Flexible Parameters (May Vary Within Functional Limits):

• Power Rating: 0.25W or higher (higher ratings provide additional margin)
• Features: Anti-sulfur, automotive AEC-Q200, moisture resistant, or pulse withstanding capabilities
• Product Status: Active or Not For New Designs (both acceptable for replacement applications)
• Physical dimensions: Minor variations in height and length within 1206 package specification

All substitute parts listed meet or exceed the critical parameters of the main part. Variations in optional features and power ratings are noted to support design flexibility.

Parameter Comparison

Engineering Selection Recommendations

For Automotive Applications with AEC-Q200 Requirement: CRCW1206348RFKEA (Vishay Dale), RMCF1206FT348R (Stackpole Electronics Inc), and ERJ-8ENF3480V (Panasonic) maintain full automotive AEC-Q200 qualification. CRCW1206348RFKEAHP provides the same automotive certification with elevated power rating (0.75W) and pulse withstanding capability for designs requiring additional thermal margin.

For General Industrial Applications: CR1206-FX-3480ELF (Bourns Inc.) and RC1206FR-07348RL (YAGEO) offer moisture-resistant thick film construction suitable for non-automotive industrial environments. Both are active products with substantial inventory availability.

For Supply Chain Continuity: RC1206FR-07348RL (YAGEO) provides the highest inventory level (66,341 units), followed by ERJ-8ENF3480V (91,569 units). Both ensure long-term availability for high-volume production requirements.

For New Design Qualification: All substitute parts except ERJ-8ENF3480V carry Active product status, making them suitable for new design implementations. ERJ-8ENF3480V is marked Not For New Designs but remains functionally equivalent for replacement and legacy support applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute ERJ-S08F3480V with a higher power-rated resistor like CRCW1206348RFKEAHP (0.75W)? A: Yes. The CRCW1206348RFKEAHP (0.75W) is a direct functional substitute with identical resistance, tolerance, package, and operating temperature range. The higher power rating provides additional thermal margin and does not degrade circuit performance. Physical dimensions vary slightly (3.10mm x 1.60mm vs. 3.20mm x 1.60mm), but both conform to 1206 package specification.

Q: What is the difference between ERJ-S08F3480V and ERJ-8ENF3480V? A: Both are Panasonic 348 Ohm ±1% 1206 resistors with identical electrical specifications. ERJ-S08F3480V (ERJ-S08 series) includes anti-sulfur coating and is currently Active. ERJ-8ENF3480V (ERJ-8EN series) is an earlier generation marked Not For New Designs but remains functionally equivalent. The ERJ-8EN series has significantly higher inventory (91,569 units).

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the environmental compliance profile of the main part.

Q: Which substitute part should I use for automotive applications? A: For automotive applications, select parts with AEC-Q200 qualification: CRCW1206348RFKEA, CRCW1206348RFKEAHP, RMCF1206FT348R, or ERJ-8ENF3480V. All maintain the -55°C ~ 155°C operating temperature range required for automotive environments.

Q: Can I use moisture-resistant variants (CR1206-FX-3480ELF, RC1206FR-07348RL) in place of AEC-Q200 parts? A: Moisture-resistant variants are functionally equivalent in terms of resistance, tolerance, and package. However, they lack automotive AEC-Q200 certification. Use them only in applications where automotive qualification is not required. For automotive designs, select AEC-Q200 qualified alternatives.

Q: What is the significance of the 1206 package specification? A: The 1206 (3216 Metric) package is a surface-mount form factor measuring 3.20mm x 1.60mm (nominal). All listed parts conform to this standard package, ensuring mechanical and electrical compatibility with existing PCB layouts and assembly processes. Minor height variations (0.024" to 0.030") do not affect functionality or assembly compatibility.
