Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F6044CS is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 6.04 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Equivalence Requirements:

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

Compliance Requirements:

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

All identified substitute parts meet these criteria. Variations in seated height and specific feature sets (anti-sulfur vs. automotive qualification vs. moisture resistant) do not affect functional substitution when electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

CRCW08056M04FKEA (Vishay Dale) is suitable for applications requiring automotive-grade qualification. This part carries AEC-Q200 certification and maintains all electrical and mechanical equivalence to the RCS2012F6044CS. The seated height of 0.020" (0.50mm) is lower than the original part, which may be advantageous in space-constrained PCB layouts. All compliance requirements are met.

RC0805FR-076M04L (YAGEO) provides direct functional equivalence with moisture-resistant thick film construction. The seated height of 0.024" (0.60mm) falls between the original and Vishay Dale options. This part is suitable for general industrial applications and meets all RoHS3 and REACH requirements.

Selection between substitute parts should be based on application-specific requirements such as automotive qualification needs, available PCB clearance, and supply chain preferences, as all three parts satisfy the core electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW08056M04FKEA replace RCS2012F6044CS in non-automotive applications?

A: Yes. The AEC-Q200 automotive qualification of CRCW08056M04FKEA does not restrict its use in non-automotive circuits. All electrical parameters, tolerance, power rating, and package dimensions are equivalent.

Q: Are there differences in reliability between the three parts?

A: All three parts are Active status with identical electrical specifications, temperature coefficients, and operating ranges. Reliability differences, if any, are determined by application-specific stress conditions and manufacturer quality systems, not by the provided technical parameters.

Q: Does the seated height difference affect PCB assembly?

A: Seated height variations (0.020" to 0.026") are within standard PCB assembly tolerances for 0805 components. Selection should consider specific PCB clearance requirements and solder reflow profiles used in manufacturing.

Q: Are all three parts suitable for high-temperature applications?

A: Yes. All parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient, meeting the specified operating range.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Unlimited) indicates these components have unlimited shelf life and require no special moisture control during storage or handling, simplifying logistics and inventory management.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Identical package type (0805), dimensions (2.00mm x 1.25mm), and termination count (2) ensure mechanical and electrical interchangeability. Seated height variations do not prevent interchangeability in standard PCB designs.
