Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F1074CS are qualified based on the following critical parameters:

Electrical Equivalence: Resistance value of 1.07 MOhms with ±1% tolerance, power rating of 0.125W (1/8W), and temperature coefficient of ±100ppm/°C must be identical.

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

Environmental & Compliance: Operating temperature range -55°C to 155°C, ROHS3 compliance, MSL 1 rating, and thick film composition must be maintained.

Material & Construction: Thick film composition is required. Additional features such as automotive AEC-Q200 qualification or anti-sulfur/moisture resistance do not disqualify substitution but represent enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

All three components—RCS2012F1074CS, CRCW08051M07FKEA, and ERJ-6ENF1074V—meet the core electrical and mechanical requirements for direct substitution. Selection between these parts is based on application-specific requirements and supply chain considerations:

RCS2012F1074CS (Samsung Electro-Mechanics): Primary specification includes anti-sulfur and moisture-resistant features. Suitable for general industrial applications requiring enhanced environmental protection.

CRCW08051M07FKEA (Vishay Dale): Includes automotive AEC-Q200 qualification. Appropriate for automotive and mission-critical applications requiring automotive-grade reliability standards. Seated height of 0.020" (0.50mm) is the lowest among the three options, beneficial for space-constrained PCB layouts.

ERJ-6ENF1074V (Panasonic Electronic Components): Includes automotive AEC-Q200 qualification. Suitable for automotive and high-reliability applications. Seated height of 0.028" (0.70mm) is the highest, which may be relevant for applications with specific clearance requirements.

All parts are ROHS3 compliant, carry MSL 1 rating, and operate across the identical temperature range of -55°C to 155°C. Selection should be based on application requirements, availability, and cost considerations rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can CRCW08051M07FKEA replace RCS2012F1074CS in a non-automotive application?

A: Yes. The CRCW08051M07FKEA meets all electrical and mechanical specifications required for substitution. The automotive AEC-Q200 qualification represents an enhanced specification that does not prevent use in non-automotive applications.

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

A: The seated heights are 0.026" (0.66mm) for RCS2012F1074CS, 0.020" (0.50mm) for CRCW08051M07FKEA, and 0.028" (0.70mm) for ERJ-6ENF1074V. These variations fall within typical PCB assembly tolerances and do not affect electrical performance. Height differences are relevant only for applications with strict vertical clearance constraints.

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

A: Yes. All three components operate across the identical temperature range of -55°C to 155°C with matching temperature coefficient of ±100ppm/°C. Temperature performance is equivalent across all options.

Q: What does MSL 1 (Unlimited) rating mean for these resistors?

A: MSL 1 indicates the lowest moisture sensitivity level. These components can be stored indefinitely without moisture bake-out requirements prior to soldering, simplifying inventory and assembly processes.

Q: Are there any compliance or certification differences between the three parts?

A: All three parts are ROHS3 compliant and REACH unaffected. The primary difference is that CRCW08051M07FKEA and ERJ-6ENF1074V carry automotive AEC-Q200 qualification, while RCS2012F1074CS emphasizes anti-sulfur and moisture-resistant construction. Both represent valid compliance frameworks for their respective application domains.

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

A: Yes. Identical package designation (0805 / 2012 Metric), matching physical dimensions (0.079" L x 0.049" W), and two-terminal configuration ensure direct PCB footprint compatibility. Height variations are within acceptable assembly tolerances.
