Substitute Part Grouping Explanation

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

Resistance value: 31.6 Ohms
Tolerance: ±1%
Power rating: 0.125W (1/8W)
Package: 0805 (2012 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
RoHS compliance: ROHS3 Compliant
Moisture sensitivity: MSL 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical specifications. Variations in packaging format (Tape & Reel versus Cut Tape), manufacturer-specific features (anti-sulfur versus moisture resistant), and physical height tolerances do not affect functional equivalence in circuit applications.

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance. Selection between the main part and substitutes depends on availability, packaging requirements, and application-specific certifications.

ERJ-6ENF31R6V (Panasonic) is a direct equivalent from the same manufacturer, available in higher quantity (83,942 units) with identical electrical specifications and physical dimensions. This part differs only in packaging format (Cut Tape & Digi-Reel versus Tape & Reel).

RMCF0805FT31R6 (Stackpole Electronics Inc) and CRCW080531R6FKEA (Vishay Dale) carry AEC-Q200 automotive ratings matching the main part specification. RMCF0805FT31R6 has lower inventory (5,949 units) while CRCW080531R6FKEA maintains 15,400 units in stock.

CR0805-FX-31R6ELF (Bourns Inc.) and RC0805FR-0731R6L (YAGEO) feature moisture-resistant properties instead of anti-sulfur treatment. RC0805FR-0731R6L has the highest inventory availability (217,531 units).

Physical height variations across substitutes (0.020" to 0.028" maximum seated height) remain within standard PCB assembly tolerances for 0805 packages and do not affect circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF31R6V replace ERJ-S06F31R6V directly?

A: Yes. Both parts are manufactured by Panasonic with identical electrical specifications (31.6Ω ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C). The difference is packaging format: ERJ-S06F31R6V is supplied in Tape & Reel while ERJ-6ENF31R6V is available in Cut Tape & Digi-Reel. Electrical performance and PCB assembly compatibility are equivalent.

Q: Are the Bourns and YAGEO parts suitable for automotive applications?

A: CR0805-FX-31R6ELF (Bourns) does not carry AEC-Q200 rating and features moisture-resistant properties. RC0805FR-0731R6L (YAGEO) also lacks AEC-Q200 certification. If automotive qualification is required, use RMCF0805FT31R6 (Stackpole) or CRCW080531R6FKEA (Vishay Dale), both AEC-Q200 rated.

Q: Do height differences affect PCB assembly?

A: No. All substitute parts maintain 0805 (2012 Metric) package geometry with maximum seated heights ranging from 0.020" to 0.028". These variations fall within standard PCB assembly specifications for 0805 components and do not impact reflow soldering, component placement, or circuit board clearance.

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

A: Anti-sulfur treatment (ERJ-S06F31R6V, ERJ-6ENF31R6V, RMCF0805FT31R6, CRCW080531R6FKEA) protects against sulfur-containing atmospheric corrosion. Moisture-resistant treatment (CR0805-FX-31R6ELF, RC0805FR-0731R6L) provides protection against humidity and moisture ingress. Both are valid protective mechanisms; selection depends on environmental exposure conditions.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts carry ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory standards.
