Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F31R6CS are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 31.6 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance & Environmental (Required):

• RoHS3 compliance
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• REACH unaffected status

All identified substitute parts meet these core parameters. Variations in seated height and packaging format (Tape & Reel vs. Cut Tape) do not affect electrical or functional interchangeability.

Engineering Selection Recommendations

All four parts listed—RC2012F31R6CS (Samsung Electro-Mechanics), RC0805FR-0731R6L (YAGEO), CRCW080531R6FKEA (Vishay Dale), and ERJ-6ENF31R6V (Panasonic Electronic Components)—are functionally equivalent for direct substitution based on matching electrical and mechanical specifications.

Selection Considerations:

RC0805FR-0731R6L (YAGEO): Direct equivalent with identical electrical parameters and moisture-resistant thick film construction. Seated height of 0.024" (0.60mm) is within acceptable tolerance for standard PCB assembly. Highest inventory availability (217,531 pcs) supports supply chain continuity.

CRCW080531R6FKEA (Vishay Dale): Qualified for automotive applications with AEC-Q200 certification. Lowest seated height of 0.020" (0.50mm) provides design flexibility for space-constrained layouts. Suitable for applications requiring automotive-grade reliability.

ERJ-6ENF31R6V (Panasonic Electronic Components): Automotive AEC-Q200 rated with ERJ-6EN series designation. Highest seated height of 0.028" (0.70mm) remains within standard PCB assembly tolerances. Available in Cut Tape and Digi-Reel packaging formats.

All parts maintain Active product status, RoHS3 compliance, and MSL 1 rating, ensuring long-term availability and regulatory compliance across industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0731R6L replace RC2012F31R6CS directly without circuit modification?

A: Yes. Both parts share identical electrical specifications (31.6 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C) and mechanical dimensions (0805 package, 2.00mm x 1.25mm). The 0.002" (0.06mm) difference in seated height does not affect PCB assembly or circuit performance.

Q: What is the difference between moisture-resistant and automotive AEC-Q200 rated resistors?

A: The RC2012F31R6CS features moisture-resistant thick film construction with MSL 1 rating. The CRCW080531R6FKEA and ERJ-6ENF31R6V include automotive AEC-Q200 certification, indicating qualification for automotive environmental stress testing and reliability standards. Both meet MSL 1 requirements; AEC-Q200 represents additional automotive-specific validation.

Q: Are there packaging format differences between these substitutes?

A: RC2012F31R6CS, RC0805FR-0731R6L, and CRCW080531R6FKEA are supplied in Tape & Reel (TR) format. ERJ-6ENF31R6V is available in Cut Tape (CT) and Digi-Reel packaging. Packaging format does not affect component electrical or mechanical performance; selection depends on assembly equipment compatibility and procurement requirements.

Q: Do all substitute parts comply with RoHS3 and REACH regulations?

A: Yes. All four parts—RC2012F31R6CS, RC0805FR-0731R6L, CRCW080531R6FKEA, and ERJ-6ENF31R6V—are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and commercial applications.

Q: Which substitute offers the best supply chain availability?

A: RC0805FR-0731R6L (YAGEO) maintains the highest inventory level at 217,531 pcs, followed by ERJ-6ENF31R6V (Panasonic) at 83,942 pcs and CRCW080531R6FKEA (Vishay Dale) at 15,400 pcs. Selection based on availability should consider project lead times and procurement timelines.

Q: Can automotive-rated parts (CRCW080531R6FKEA, ERJ-6ENF31R6V) be used in non-automotive applications?

A: Yes. Automotive AEC-Q200 certification represents additional qualification beyond standard industrial requirements. These parts are fully compatible with non-automotive applications and provide enhanced reliability margins.
