Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F4024CS is determined by strict equivalence across the following parameters:

Electrical Specifications: Resistance value (4.02 MOhms), tolerance (±1%), and power rating (0.125W) must be identical.

Package Compatibility: All substitute parts must use the 0805 (2012 Metric) package with identical mechanical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm).

Environmental & Compliance Requirements: Operating temperature range (-55°C ~ 155°C), temperature coefficient (±100ppm/°C), RoHS3 compliance, and MSL 1 rating must be maintained.

Composition: Thick film construction is required for all substitutes.

The identified substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable with the RCS2012F4024CS.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RCS2012F4024CS, CRCW08054M02FKEA, and RC0805FR-074M02L—are Active status components with full RoHS3 compliance and MSL 1 ratings. They are electrically and mechanically equivalent for direct substitution in 0805 package applications requiring 4.02 MOhms ±1% at 0.125W.

The CRCW08054M02FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications where such certification is required. The RCS2012F4024CS and RC0805FR-074M02L provide standard industrial-grade performance with moisture-resistant properties.

Selection between these parts should be based on supply chain availability, cost considerations, and specific application requirements regarding automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can CRCW08054M02FKEA replace RCS2012F4024CS in non-automotive applications?

A: Yes. The CRCW08054M02FKEA meets all electrical and mechanical specifications of the RCS2012F4024CS. AEC-Q200 certification is an additional qualification that does not restrict use in standard applications.

Q: Are there dimensional differences between these 0805 packages?

A: All three parts conform to 0805 (2012 Metric) package dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Maximum seated heights vary slightly (0.026" for RCS2012F4024CS, 0.020" for CRCW08054M02FKEA, 0.024" for RC0805FR-074M02L) but remain within standard 0805 specifications and do not affect PCB layout compatibility.

Q: Do all substitutes maintain the same temperature performance?

A: Yes. All three parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient, ensuring equivalent thermal performance.

Q: What is the significance of MSL 1 rating for these parts?

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: Are these parts suitable for high-reliability applications?

A: All three parts carry RoHS3 compliance and are Active status components from established manufacturers. Selection for high-reliability applications should consider specific application requirements and manufacturer datasheets for additional reliability metrics.
