ERJ-S08F17R8V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F17R8V is a 17.8 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 applications requiring high reliability in automotive and industrial environments. The product is currently active with 1159 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift to alternative manufacturers, or when supply chain optimization requires qualified alternatives that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S08F17R8V is determined by strict equivalence across the following parameters:

Resistance value: 17.8 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)
RoHS compliance: ROHS3 Compliant (exact match required)
Moisture sensitivity: MSL 1 (exact match required)

All five substitute parts listed below meet these criteria. Variations in physical dimensions (length, width, height) and manufacturer-specific features (anti-sulfur vs. moisture resistant coatings) do not affect electrical substitutability when all core parameters are identical.

Engineering Selection Recommendations

For new designs, select from parts with Active product status: CR1206-FX-17R8ELF (Bourns), CRCW120617R8FKEA (Vishay Dale), RC1206FR-0717R8L (YAGEO), or RMCF1206FT17R8 (Stackpole Electronics Inc).

For automotive applications requiring AEC-Q200 qualification, the following parts are certified: ERJ-S08F17R8V (primary), CRCW120617R8FKEA (Vishay Dale), and RMCF1206FT17R8 (Stackpole Electronics Inc).

The ERJ-8ENF17R8V (Panasonic) carries "Not For New Designs" status and should be used only for legacy system maintenance or existing production continuity where design changes are not feasible.

All listed substitutes are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF17R8V replace ERJ-S08F17R8V in new designs?

A: No. ERJ-8ENF17R8V carries "Not For New Designs" status. Use this part only for legacy system support or existing production lines. For new designs, select from active-status alternatives.

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

A: Yes. While all parts use the 1206 package, length, width, and height vary slightly between manufacturers. Typical variations: length 0.122" to 0.126", height 0.024" to 0.030". These variations are within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Which substitute parts have AEC-Q200 automotive qualification?

A: CRCW120617R8FKEA (Vishay Dale) and RMCF1206FT17R8 (Stackpole Electronics Inc) are AEC-Q200 qualified. CR1206-FX-17R8ELF (Bourns) and RC1206FR-0717R8L (YAGEO) are not AEC-Q200 qualified but are suitable for non-automotive applications.

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

A: Both coatings protect the resistor element. Anti-sulfur coating specifically prevents sulfur corrosion in harsh environments. Moisture-resistant coating protects against humidity ingress. Both meet MSL 1 requirements. Selection depends on application environment.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, meeting standard PCB assembly and storage requirements.

Q: Can I mix different manufacturers in the same PCB assembly?

A: Yes. All substitute parts meet identical electrical and mechanical specifications. Mixed-manufacturer assemblies are acceptable from an engineering standpoint, though procurement and quality documentation practices may vary by organization.
