Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F1184CS is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 1.18 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All identified substitute parts meet these electrical and mechanical specifications. Substitute parts may include additional certifications (such as AEC-Q200 automotive qualification) or enhanced feature sets (such as automotive-grade construction) beyond the base requirements, which do not preclude substitution but represent extended capability.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RCS2012F1184CS, CRCW08051M18FKEA, ERJ-6ENF1184V, and RC0805FR-071M18L—are electrically and mechanically equivalent for direct substitution in 0805 thick film resistor applications requiring 1.18 MOhm ±1% 0.125W specifications.

CRCW08051M18FKEA (Vishay Dale) carries AEC-Q200 automotive qualification, indicating suitability for automotive-grade applications. This part is appropriate for designs requiring automotive compliance or enhanced reliability screening.

ERJ-6ENF1184V (Panasonic Electronic Components) also carries AEC-Q200 automotive qualification and represents an alternative automotive-qualified option with equivalent electrical performance.

RC0805FR-071M18L (YAGEO) provides moisture-resistant construction without automotive qualification, suitable for general industrial and consumer applications where automotive certification is not required.

All parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical operating temperature ranges. Selection between these parts is determined by application-specific requirements such as automotive qualification necessity, supply availability, or preferred manufacturer relationships.

Frequently Asked Questions (FAQ)

Q: Can CRCW08051M18FKEA replace RCS2012F1184CS in any application?

A: CRCW08051M18FKEA is electrically and mechanically equivalent to RCS2012F1184CS. Both components share identical resistance, tolerance, power rating, package dimensions, and operating specifications. The primary difference is that CRCW08051M18FKEA includes AEC-Q200 automotive qualification. Direct substitution is valid for all applications where the RCS2012F1184CS is specified.

Q: What is the significance of AEC-Q200 qualification on ERJ-6ENF1184V and CRCW08051M18FKEA?

A: AEC-Q200 is an automotive industry standard qualification that certifies components for automotive applications. Parts carrying this qualification have undergone additional reliability testing and screening. For non-automotive applications, this certification does not affect electrical performance but indicates enhanced quality assurance. For automotive designs, AEC-Q200 qualification may be a requirement.

Q: Are there physical mounting differences between these substitute parts?

A: All four parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Seated height varies slightly: RCS2012F1184CS (0.026" / 0.66mm), CRCW08051M18FKEA (0.020" / 0.50mm), ERJ-6ENF1184V (0.028" / 0.70mm), and RC0805FR-071M18L (0.024" / 0.60mm). These height variations are within standard PCB assembly tolerances and do not affect interchangeability for standard surface-mount applications.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: All four parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Components with MSL 1 do not require special moisture control during storage, handling, or assembly.

Q: Which substitute part should be selected for cost optimization?

A: Selection based on cost is determined by current market pricing and supplier inventory levels. RC0805FR-071M18L (YAGEO) and RCS2012F1184CS (Samsung) are general-purpose options without automotive qualification. CRCW08051M18FKEA (Vishay Dale) and ERJ-6ENF1184V (Panasonic) include automotive qualification and may carry different pricing. Consult current supplier quotations for cost comparison.

Q: Are these parts suitable for high-temperature applications?

A: All four parts operate across the identical temperature range of -55°C to 155°C with ±100ppm/°C temperature coefficient. This specification applies uniformly across all substitute options.

Q: Can these parts be used interchangeably in existing designs without PCB modification?

A: Yes. All parts conform to the 0805 (2012 Metric) package standard with compatible footprints. The minor height variations do not require PCB redesign for standard surface-mount assembly processes.
