Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F2213CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (221 kOhms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Compatibility: Package type (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W), and number of terminations (2) must be identical to ensure PCB footprint compatibility.

Environmental & Compliance Requirements: Operating temperature range (-55°C ~ 155°C), RoHS3 compliance, and MSL 1 rating must be maintained.

All four substitute parts listed meet these criteria and are therefore electrically and mechanically interchangeable with the main part number RCS2012F2213CS.

RC0805FR-07221KL (YAGEO): Standard industrial grade without automotive certification. Mid-range seated height at 0.024" (0.60mm). Suitable for general industrial applications.

RMCF0805FT221K (Stackpole Electronics Inc): Automotive AEC-Q200 rated. Seated height at 0.026" (0.65mm), matching the main part. Suitable for automotive applications.

Selection between these parts depends on application requirements regarding automotive qualification and available inventory levels.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805221KFKEA replace RCS2012F2213CS directly on the PCB?

A: Yes. Both parts share identical electrical specifications (221 kOhms ±1%, 0.125W, ±100ppm/°C), package type (0805), and operating temperature range (-55°C ~ 155°C). The height difference (0.020" vs 0.026") is within typical PCB assembly tolerances and does not affect footprint compatibility.

Q: What is the difference between automotive AEC-Q200 rated and non-rated substitutes?

A: CRCW0805221KFKEA, ERJ-6ENF2213V, and RMCF0805FT221K carry AEC-Q200 automotive qualification. RC0805FR-07221KL does not. AEC-Q200 certification indicates compliance with automotive reliability and quality standards. Selection depends on whether the application requires automotive-grade components.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All five parts, including the main part RCS2012F2213CS, are ROHS3 compliant with MSL 1 rating, ensuring regulatory compliance and unlimited moisture sensitivity protection.

Q: Does seated height variation affect PCB assembly?

A: Seated height ranges from 0.020" to 0.028" across all parts. These variations fall within standard PCB assembly specifications for 0805 components and do not require design modifications.

Q: Which substitute offers the best inventory availability?

A: ERJ-6ENF2213V (Panasonic) offers the highest inventory at 119,309 pcs, followed by RMCF0805FT221K (Stackpole) at 80,394 pcs.
