ERJ-S08F17R4V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F17R4V is a 17.4 Ohm ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Panasonic Electronic Components. This part is classified as Active product status and features anti-sulfur coating with automotive AEC-Q200 qualification. Substitute parts are necessary when the primary part experiences supply constraints, inventory depletion, or when design requirements permit selection from qualified alternative manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Resistance value: 17.4 Ohms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.25W (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 level: 1 (Unlimited) (exact match required)

All substitute parts listed meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification, feature sets (anti-sulfur vs. moisture resistant), and product status do not disqualify substitution when electrical and mechanical parameters are identical.

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the ERJ-S08F17R4V. Selection among these alternatives should be based on the following criteria:

Product Status Consideration: The ERJ-8ENF17R4V carries "Not For New Designs" status and should be avoided for new circuit designs. The CRCW120617R4FKEA (Vishay Dale), RC1206FR-0717R4L (YAGEO), and RMCF1206FT17R4 (Stackpole Electronics Inc) all maintain Active product status and are suitable for new designs.

Compliance and Certifications: The ERJ-S08F17R4V, CRCW120617R4FKEA, and RMCF1206FT17R4 carry automotive AEC-Q200 qualification. The RC1206FR-0717R4L does not list AEC-Q200 rating but meets all electrical and mechanical specifications. Selection depends on whether automotive qualification is a design requirement.

Feature Differentiation: The ERJ-S08F17R4V includes anti-sulfur coating. The RC1206FR-0717R4L specifies moisture resistant composition. These feature differences do not affect substitution eligibility when electrical parameters are identical.

Inventory and Availability: Substitute selection may be influenced by stock levels and lead times from authorized distributors.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF17R4V replace ERJ-S08F17R4V in new designs?

A: ERJ-8ENF17R4V is electrically and mechanically equivalent but carries "Not For New Designs" status. It is suitable only for legacy system maintenance or replacement applications. New designs should use CRCW120617R4FKEA, RC1206FR-0717R4L, or RMCF1206FT17R4.

Q: Does the absence of AEC-Q200 rating on RC1206FR-0717R4L disqualify it as a substitute?

A: AEC-Q200 qualification is a feature, not a core electrical or mechanical parameter. RC1206FR-0717R4L meets all specified electrical and mechanical requirements. Its suitability depends on whether your application requires automotive qualification.

Q: Are physical dimension variations within the 1206 package significant?

A: All parts conform to 1206 (3216 Metric) package specification. Minor variations in length (0.122" to 0.126"), width (0.063"), and height (0.024" to 0.028") are within standard package tolerances and do not affect PCB footprint compatibility or substitution eligibility.

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

A: Anti-sulfur coating protects against sulfur-containing atmospheric contaminants. Moisture resistant composition provides protection against humidity. Both are protective features that do not alter electrical performance or substitution compatibility.

Q: Can I use these substitutes interchangeably in existing assemblies?

A: Yes. All substitute parts are pin-compatible, electrically equivalent, and mechanically compatible with the 1206 footprint. No circuit modifications or PCB redesign is required.
