Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F31R6CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 31.6 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package format: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Variations in physical height, packaging format (Tape & Reel vs. Cut Tape), and optional certifications (such as AEC-Q200 automotive qualification) do not preclude substitution when core parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

All four components listed—RCS2012F31R6CS, CRCW080531R6FKEA, ERJ-6ENF31R6V, and RC0805FR-0731R6L—are Active product status and fully compliant with ROHS3 regulations. Selection among these parts is based on availability, packaging preference, and optional certifications:

CRCW080531R6FKEA (Vishay Dale): Includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability standards.

ERJ-6ENF31R6V (Panasonic): Includes AEC-Q200 automotive qualification and is available in Cut Tape (CT) & Digi-Reel® packaging format, offering flexibility for both automated and manual assembly processes.

RC0805FR-0731R6L (YAGEO): Moisture-resistant thick film construction without automotive certification, available in Tape & Reel format with highest inventory availability.

RCS2012F31R6CS (Samsung): Anti-sulfur and moisture-resistant construction, available in Tape & Reel format with active product status.

All parts maintain identical electrical performance across the specified operating temperature range and tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW080531R6FKEA replace RCS2012F31R6CS in non-automotive applications?

A: Yes. The AEC-Q200 automotive certification on CRCW080531R6FKEA does not restrict its use in non-automotive circuits. All electrical and mechanical parameters are identical to RCS2012F31R6CS.

Q: What is the significance of the height difference between substitute parts?

A: Height variations (0.020" to 0.028" seated maximum) fall within standard PCB assembly tolerances for 0805 package components. All parts are mechanically compatible with standard 0805 footprints.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical specifications remain identical regardless of packaging method.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting environmental and hazardous substance restrictions.

Q: Can ERJ-6ENF31R6V be used in high-moisture environments?

A: Yes. ERJ-6ENF31R6V carries MSL rating 1 (Unlimited), indicating no moisture sensitivity limitations. All substitute parts share this MSL classification.
