Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F6043CS are qualified based on the following criteria:

Electrical Equivalence: Resistance value of 604 kOhms, tolerance of ±1%, and power rating of 0.125W (1/8W) must be identical.

Mechanical Compatibility: Package designation 0805 (2012 Metric) with physical dimensions 0.079" L x 0.049" W (2.00mm x 1.25mm) ensures PCB footprint compatibility.

Environmental Performance: Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C ~ 155°C must match or exceed the original specification.

Regulatory Compliance: RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) are required for direct substitution.

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

All identified substitute parts meet these criteria and are classified as Active product status.

Parameter Comparison

Engineering Selection Recommendations

All four components listed—RCS2012F6043CS, CRCW0805604KFKEA, ERJ-6ENF6043V, and RC0805FR-07604KL—are Active product status and fully compliant with RoHS3 regulations. Each component carries MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or handling.

CRCW0805604KFKEA (Vishay Dale) and ERJ-6ENF6043V (Panasonic) include AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

RC0805FR-07604KL (YAGEO) is supplied in Cut Tape (CT) & Digi-Reel® packaging, whereas the original RCS2012F6043CS and other substitutes are supplied in Tape & Reel (TR) format. Packaging format selection depends on assembly process requirements.

Height variation among substitutes ranges from 0.020" to 0.028" (0.50mm to 0.70mm). All values remain within typical PCB assembly clearance specifications for 0805 components.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805604KFKEA replace RCS2012F6043CS in any application?

A: Yes. Both components share identical electrical specifications (604 kOhms ±1%, 0.125W), package dimensions (0805/2012 Metric), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and regulatory compliance (RoHS3, MSL 1). The CRCW0805604KFKEA includes AEC-Q200 automotive qualification, making it suitable for automotive and industrial applications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on cut tape segments, typically used for lower-volume or manual assembly processes. Electrical and mechanical specifications remain identical regardless of packaging format.

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

A: Yes. All listed components operate across the identical temperature range of -55°C ~ 155°C with ±100ppm/°C temperature coefficient, ensuring stable resistance performance across the full operating spectrum.

Q: Does the height difference between substitutes affect PCB assembly?

A: Height variation (0.020" to 0.028" maximum seated height) is within standard PCB assembly tolerances for 0805 components. Component height does not affect electrical performance or footprint compatibility. Assembly process parameters may require minor adjustment for components at height extremes, but direct substitution is mechanically feasible.

Q: Which substitute offers the best availability?

A: ERJ-6ENF6043V (Panasonic) shows highest inventory at 37,519 pieces, followed by CRCW0805604KFKEA (Vishay Dale) at 23,970 pieces. RC0805FR-07604KL (YAGEO) maintains 6,610 pieces in stock. Availability should be verified with current supplier inventory at time of procurement.

Q: Are these components suitable for moisture-sensitive environments?

A: Yes. All components carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly processes.
