Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F43R2CS are qualified based on the following criteria:

Electrical Equivalence: Resistance value of 43.2 Ohms, tolerance of ±1%, power rating of 0.125W (1/8W), temperature coefficient of ±100ppm/°C, and operating temperature range of -55°C to 155°C must be identical.

Mechanical Compatibility: Package designation 0805 (2012 Metric) with two terminations ensures footprint and land pattern compatibility on printed circuit boards.

Environmental & Compliance Standards: RoHS3 compliance, Moisture Sensitivity Level 1, and REACH unaffected status must be maintained across all substitute options.

Composition & Construction: Thick film construction is required for all substitutes to maintain electrical performance characteristics.

The three substitute parts listed below meet all specified criteria and are therefore electrically and mechanically interchangeable with the RCS2012F43R2CS.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are Active product status components with full RoHS3 compliance and REACH unaffected designation, matching the regulatory and environmental requirements of the RCS2012F43R2CS.

CRCW080543R2FKEA (Vishay Dale): This substitute carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. Height-seated maximum is 0.020" (0.50mm), the lowest among all options.

ERJ-6ENF43R2V (Panasonic Electronic Components): This substitute includes AEC-Q200 automotive qualification and offers the highest inventory availability at 119,336 pieces. Height-seated maximum is 0.028" (0.70mm).

RC0805FR-0743R2L (YAGEO): This substitute features moisture resistant construction matching the original part's environmental protection. Height-seated maximum is 0.024" (0.60mm), positioned between the other two options. Inventory availability is 110,297 pieces.

Selection among these three substitutes depends on application-specific requirements regarding automotive qualification and available board space for component height.

Frequently Asked Questions (FAQ)

Q: Can CRCW080543R2FKEA replace RCS2012F43R2CS in non-automotive applications?

A: Yes. The CRCW080543R2FKEA meets all electrical and mechanical specifications of the RCS2012F43R2CS. AEC-Q200 qualification is an additional feature that does not restrict use in non-automotive circuits.

Q: Are there dimensional differences that affect PCB layout?

A: All four parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Height-seated maximum values differ slightly: RCS2012F43R2CS at 0.026" (0.66mm), CRCW080543R2FKEA at 0.020" (0.50mm), ERJ-6ENF43R2V at 0.028" (0.70mm), and RC0805FR-0743R2L at 0.024" (0.60mm). These variations are within standard PCB assembly tolerances and do not require design modification.

Q: Do all substitutes maintain the same temperature coefficient?

A: Yes. All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, identical to the RCS2012F43R2CS.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Unlimited) indicates unlimited shelf life without moisture bake-out requirements. All four parts carry this rating, ensuring consistent handling and storage procedures.

Q: Are there compliance differences between the main part and substitutes?

A: No. All parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification with identical HTSUS code 8533.21.0030.
