Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F4641CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (4.64 kOhms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Compatibility: Package type (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), and number of terminations (2) must match to ensure PCB footprint compatibility.

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

All four substitute parts listed below meet these criteria and are qualified for direct replacement in applications where the RCS2012F4641CS is specified.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products with ROHS3 compliance and REACH unaffected status, meeting the regulatory requirements of the original RCS2012F4641CS.

CRCW08054K64FKEA (Vishay Dale): Automotive AEC-Q200 rated. Lowest seated height at 0.020" (0.50mm). Suitable for applications requiring automotive-grade reliability with high inventory availability (28,775 pieces).

ERJ-6ENF4641V (Panasonic Electronic Components): Automotive AEC-Q200 rated. Highest seated height at 0.028" (0.70mm). Largest inventory stock (255,325 pieces). Appropriate for automotive and industrial applications requiring extended supply assurance.

RC0805FR-074K64L (YAGEO): Non-automotive grade with moisture-resistant features. Available in Cut Tape and Digi-Reel® packaging. Seated height 0.024" (0.60mm). Highest inventory availability (360,912 pieces). Suitable for general industrial and consumer applications.

RMCF0805FT4K64 (Stackpole Electronics Inc): Automotive AEC-Q200 rated. Seated height 0.026" (0.65mm), matching the original part. Moderate inventory (18,637 pieces). Appropriate for automotive applications requiring dimensional consistency with the original design.

Selection should be based on application requirements: automotive applications benefit from AEC-Q200 rated alternatives; general applications may use the YAGEO option; dimensional constraints may favor the Stackpole part for height-sensitive designs.

Frequently Asked Questions (FAQ)

Q: Can CRCW08054K64FKEA replace RCS2012F4641CS in all applications?

A: CRCW08054K64FKEA meets all electrical and mechanical specifications for direct substitution. The lower seated height (0.020" vs 0.026") is compatible with standard 0805 PCB footprints. Automotive AEC-Q200 certification provides additional reliability assurance for demanding environments.

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

A: Automotive AEC-Q200 rated parts (CRCW08054K64FKEA, ERJ-6ENF4641V, RMCF0805FT4K64) undergo additional qualification testing for automotive applications. The non-automotive RC0805FR-074K64L is suitable for general industrial and consumer applications but lacks automotive certification.

Q: Are there packaging differences between substitutes?

A: Three substitutes (CRCW08054K64FKEA, ERJ-6ENF4641V, RMCF0805FT4K64) are supplied in Tape & Reel (TR) packaging, matching the original. RC0805FR-074K64L is available in Cut Tape (CT) and Digi-Reel® packaging, which may affect handling and assembly processes.

Q: Does seated height variation affect PCB assembly?

A: All seated heights (0.020" to 0.028") fall within standard 0805 component tolerances and are compatible with typical PCB designs. Height differences are negligible for most applications but should be verified for space-constrained designs or automated assembly processes.

Q: Are all substitutes ROHS3 compliant?

A: Yes, all four substitute parts are ROHS3 compliant and REACH unaffected, matching the environmental compliance status of the original RCS2012F4641CS.

Q: Which substitute has the best inventory availability?

A: RC0805FR-074K64L (YAGEO) has the highest inventory at 360,912 pieces, followed by ERJ-6ENF4641V (Panasonic) at 255,325 pieces. Both provide excellent supply assurance for high-volume production.
