Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F3924CS is determined by strict equivalence across the following parameters:

Electrical Parameters: Resistance value (3.92 MOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) must match exactly.

Mechanical Parameters: Package type (0805 / 2012 Metric), number of terminations (2), and physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) must be identical.

Composition & Construction: Thick film construction is required for substitution.

Compliance & Certifications: RoHS3 compliance and MSL 1 rating are mandatory. Additional certifications (such as AEC-Q200) do not disqualify a substitute but represent enhanced qualification.

Packaging: Tape & Reel (TR) packaging format applies to all identified substitutes.

The two substitute parts listed below satisfy all mandatory electrical, mechanical, and compliance criteria.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RCS2012F3924CS, CRCW08053M92FKEA, and RC0805FR-073M92L—are Active status components with identical electrical specifications and ROHS3 compliance. Selection between these parts is based on application-specific requirements and supply chain considerations.

CRCW08053M92FKEA (Vishay Dale) carries AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications requiring automotive-grade component certification. This part features the lowest seated height at 0.020" (0.50mm).

RC0805FR-073M92L (YAGEO) provides moisture-resistant thick film construction with intermediate seated height of 0.024" (0.60mm), suitable for general industrial and consumer applications.

RCS2012F3924CS (Samsung) includes anti-sulfur and moisture-resistant features with seated height of 0.026" (0.66mm), appropriate for environments with corrosive exposure risk.

All parts maintain identical electrical performance, temperature stability, and compliance certifications. Component selection should account for application environment, PCB assembly constraints related to component height, and supply availability.

Frequently Asked Questions (FAQ)

Q: Can CRCW08053M92FKEA replace RCS2012F3924CS in any application?

A: CRCW08053M92FKEA meets all electrical and mechanical substitution criteria. The primary difference is AEC-Q200 automotive qualification and lower seated height (0.020" vs 0.026"). Substitution is valid for applications where these differences do not create constraints.

Q: What is the significance of the seated height difference between these parts?

A: Seated height varies from 0.020" (CRCW08053M92FKEA) to 0.026" (RCS2012F3924CS). In high-density PCB layouts or applications with height restrictions, the lower-profile Vishay part may be preferred. In standard applications, this difference is not functionally significant.

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

A: All three parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient. They are functionally equivalent for temperature performance across this range.

Q: Does AEC-Q200 certification on CRCW08053M92FKEA make it superior for non-automotive use?

A: AEC-Q200 represents additional automotive-grade qualification testing. For non-automotive applications, this certification provides enhanced reliability assurance but is not required. All three parts meet ROHS3 and MSL 1 requirements for standard industrial use.

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

A: Yes, all three parts are mechanically and electrically interchangeable in 0805 package footprints. Tape & Reel packaging is standard across all parts, supporting automated assembly processes without modification.

Q: What distinguishes the anti-sulfur feature of RCS2012F3924CS?

A: Anti-sulfur treatment protects against sulfur-induced corrosion in environments with hydrogen sulfide exposure or high-sulfur industrial atmospheres. This feature is specific to Samsung's RCS series and not present in the Vishay or YAGEO alternatives. Selection of RCS2012F3924CS is appropriate for corrosive industrial environments.
