Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F4873CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence: Resistance value (487 kOhms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Compatibility: Package designation (0805/2012 Metric), physical dimensions (0.079" L × 0.049" W / 2.00mm × 1.25mm), and termination count (2) must match.

Environmental & Compliance: Operating temperature range (-55°C to 155°C), Moisture Sensitivity Level (MSL 1), RoHS3 compliance, and REACH status must be maintained.

Composition & Construction: Thick film construction is required for all substitutes.

All three identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the RCS2012F4873CS.

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the RCS2012F4873CS and maintain Active product status with full RoHS3 and REACH compliance. Selection among these alternatives should be based on the following considerations:

CRCW0805487KFKEA (Vishay Dale): Features automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability standards. Seated height of 0.020" (0.50mm) is the lowest among all options, beneficial for space-constrained PCB layouts.

ERJ-6ENF4873V (Panasonic): Also carries automotive AEC-Q200 qualification. Highest inventory availability (118,150 pcs) ensures supply continuity. Seated height of 0.028" (0.70mm) is the maximum among substitutes.

RC0805FR-07487KL (YAGEO): Offers moisture-resistant construction matching the original RCS2012F4873CS specification. Seated height of 0.024" (0.60mm) provides mid-range clearance characteristics. Substantial inventory (12,223 pcs) supports production requirements.

All parts maintain identical electrical performance and thermal characteristics across the specified operating range. Height variations are within acceptable tolerances for standard 0805 package applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805487KFKEA replace RCS2012F4873CS in non-automotive applications?

A: Yes. The CRCW0805487KFKEA meets all electrical and mechanical specifications required for direct substitution. AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits.

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

A: The seated height variations (0.020" to 0.028") are within standard 0805 package tolerances. Selection should consider PCB clearance requirements and assembly equipment specifications. All heights remain compatible with standard pick-and-place and reflow processes.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All identified substitutes are supplied in Tape & Reel (TR) format, matching the original RCS2012F4873CS packaging specification.

Q: Do the substitute parts maintain the same moisture sensitivity level?

A: Yes. All substitutes carry MSL 1 (Unlimited) rating, identical to the original component. This indicates no moisture precautions are required during storage or handling.
