Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F6340CS is determined by strict equivalence across the following parameters:

Electrical Specifications: Resistance value (634 Ohms), tolerance (±1%), and power rating (0.125W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (0805 / 2012 Metric) and number of terminations (2) ensure physical and electrical interface compatibility with printed circuit board layouts.

Compliance & Certification: RoHS3 compliance and MSL Level 1 rating are required for environmental and handling consistency. Product status must be Active.

Composition: Thick film construction maintains electrical performance characteristics across the specified temperature range.

All four substitute parts listed meet these criteria without exception.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RCS2012F6340CS based on electrical and mechanical parameter alignment. Selection among these alternatives is determined by application-specific requirements and supply chain considerations:

CRCW0805634RFKEA (Vishay Dale): Automotive AEC-Q200 rated. Suitable for automotive and high-reliability applications requiring automotive-grade qualification.

ERJ-6ENF6340V (Panasonic Electronic Components): Automotive AEC-Q200 rated with highest inventory availability (322,201 pcs). Suitable for automotive applications and high-volume production environments.

RC0805FR-07634RL (YAGEO): Moisture-resistant thick film construction. Suitable for general industrial applications with high inventory availability (147,347 pcs).

RMCF0805FT634R (Stackpole Electronics Inc): Automotive AEC-Q200 rated. Suitable for automotive applications requiring automotive-grade qualification.

All parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring environmental and handling consistency with the original component.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805634RFKEA replace RCS2012F6340CS in non-automotive applications?

A: Yes. CRCW0805634RFKEA meets all electrical and mechanical specifications required for direct substitution. Automotive AEC-Q200 certification indicates enhanced reliability and does not restrict use in non-automotive circuits.

Q: What is the difference between anti-sulfur and moisture-resistant features listed for different parts?

A: Both features address environmental protection. Anti-sulfur protection (RCS2012F6340CS) and moisture-resistant construction (RC0805FR-07634RL) are material-level characteristics that do not affect electrical performance or substitution eligibility. All parts maintain MSL Level 1 rating.

Q: Are there physical dimension differences among substitute parts?

A: All parts conform to 0805 (2012 Metric) package specification with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Height-seated maximum values vary slightly (0.020" to 0.028"), which does not affect PCB assembly compatibility.

Q: Which substitute part has the best supply availability?

A: ERJ-6ENF6340V (Panasonic) has the highest inventory level at 322,201 pcs. RC0805FR-07634RL (YAGEO) is second with 147,347 pcs.

Q: Do all substitute parts support the same operating temperature range?

A: Yes. All substitute parts operate across -55°C ~ 155°C with ±100ppm/°C temperature coefficient, matching the original RCS2012F6340CS specification.

Q: Is packaging format (Tape & Reel vs. Cut Tape) a substitution factor?

A: Packaging format affects supply chain logistics and handling but does not impact electrical or mechanical compatibility. CRCW0805634RFKEA is supplied in Cut Tape & Digi-Reel format, while other substitutes use Tape & Reel format.
