ERJ-S08F34R8V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F34R8V is a 34.8 Ohm ±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 automotive and industrial applications requiring high reliability in harsh environments. The product is currently active and available in high volume inventory (940 pcs).

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility allows for alternative qualified sources while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S08F34R8V is determined by strict equivalence across the following critical parameters:

• Resistance value: 34.8 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Package: 1206 (3216 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)
• Termination count: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All four substitute parts listed meet these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are electrically and mechanically equivalent to the ERJ-S08F34R8V based on the provided specifications.

For new designs, select from parts with Active product status: CRCW120634R8FKEA (Vishay Dale), RC1206FR-0734R8L (YAGEO), or RMCF1206FT34R8 (Stackpole Electronics). These three parts offer long-term availability and design support.

The ERJ-8ENF34R8V (Panasonic) carries a "Not For New Designs" status and should be used only for legacy system maintenance or when existing design documentation specifies this part number.

For automotive applications requiring AEC-Q200 qualification, ERJ-S08F34R8V, ERJ-8ENF34R8V, CRCW120634R8FKEA, and RMCF1206FT34R8 all meet this requirement. RC1206FR-0734R8L does not carry explicit AEC-Q200 rating but features moisture-resistant construction.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF34R8V be used as a direct replacement for ERJ-S08F34R8V?

A: Yes, ERJ-8ENF34R8V is electrically and mechanically equivalent. However, it carries a "Not For New Designs" status. Use this part only for legacy system repairs or when existing documentation specifies this part number.

Q: What is the difference between the anti-sulfur feature on ERJ-S08F34R8V and the moisture-resistant feature on RC1206FR-0734R8L?

A: Both features address environmental protection but target different degradation mechanisms. Anti-sulfur coating protects against sulfur-containing atmospheric contaminants common in industrial environments. Moisture-resistant construction protects against humidity-induced corrosion. Both parts meet MSL 1 requirements and operate across the same temperature range.

Q: Are all substitute parts suitable for automotive applications?

A: ERJ-S08F34R8V, ERJ-8ENF34R8V, CRCW120634R8FKEA, and RMCF1206FT34R8 carry AEC-Q200 automotive qualification. RC1206FR-0734R8L does not carry explicit AEC-Q200 rating. For automotive applications requiring AEC-Q200 compliance, use one of the four qualified parts.

Q: Do all parts have identical physical dimensions?

A: All parts use the 1206 (3216 Metric) package. Minor variations exist in maximum seated height: ERJ-S08F34R8V and RMCF1206FT34R8 are 0.028" (0.70mm), CRCW120634R8FKEA is 0.024" (0.60mm), and RC1206FR-0734R8L is 0.026" (0.65mm). These variations are within standard PCB assembly tolerances and do not affect interchangeability.

Q: Which substitute part offers the best long-term availability?

A: CRCW120634R8FKEA (Vishay Dale) and RC1206FR-0734R8L (YAGEO) both carry Active product status with substantial inventory levels (15,592 and 23,081 pcs respectively), indicating strong long-term availability.
