Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F4874CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

• Resistance value: 4.87 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Critical Mechanical Parameters:

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

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part CRCW08054M87FKEA manufactured by Vishay Dale meets all critical electrical and mechanical parameters. Both components share identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. Package dimensions and termination count are equivalent. Both components maintain ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

The CRCW08054M87FKEA from Vishay Dale is a direct electrical and mechanical equivalent to the RCS2012F4874CS. Both components satisfy identical electrical specifications across resistance, tolerance, power rating, and temperature performance. Package compatibility is confirmed through matching 0805 (2012 Metric) form factor and equivalent physical dimensions.

Both components maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The CRCW08054M87FKEA includes AEC-Q200 automotive qualification, which represents an additional certification tier beyond the base RCS2012F4874CS specification. This additional qualification does not restrict substitution in non-automotive applications.

The seated height difference (0.026" versus 0.020" maximum) is within acceptable tolerance for standard PCB assembly processes and does not impact electrical performance or mechanical fit in standard 0805 footprints.

Frequently Asked Questions (FAQ)

Q: Can CRCW08054M87FKEA replace RCS2012F4874CS in all applications?

A: Yes. Both components share identical electrical specifications (4.87 MOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C) and mechanical package (0805 2012 Metric). Compliance certifications (ROHS3, MSL 1) are equivalent.

Q: What is the significance of the AEC-Q200 rating on the Vishay part?

A: AEC-Q200 is an automotive qualification standard. The CRCW08054M87FKEA meets this additional requirement, but this does not restrict its use in non-automotive circuits. It represents a higher qualification level than the base RCS2012F4874CS.

Q: Are the physical dimensions truly equivalent?

A: Yes. Both components measure 0.079" L x 0.049" W (2.00mm x 1.25mm). The seated height maximum differs slightly (0.026" versus 0.020"), but both values fall within standard PCB assembly tolerances for 0805 packages and do not affect footprint compatibility.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both RCS2012F4874CS and CRCW08054M87FKEA are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical electrical performance, package type, and compliance certifications enable direct substitution without circuit redesign or PCB layout modification.
