Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F71R5CS is determined by strict equivalence across the following parameters:

• Electrical Specifications: Resistance value (71.5 Ohms), tolerance (±1%), and power rating (0.125W) must be identical
• Package Compatibility: 0805 (2012 Metric) package format with matching termination count (2 terminations)
• Thermal Performance: Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) must be equivalent
• Compliance & Environmental: ROHS3 compliance and MSL 1 rating required
• Physical Dimensions: Length 0.079" (2.00mm), width 0.049" (1.25mm), with seated height variations within acceptable limits

All identified substitute parts meet these criteria and are classified as Active products with equivalent thick film composition.

Parameter Comparison

Engineering Selection Recommendations

All four components listed—RCS2012F71R5CS, CRCW080571R5FKEA, ERJ-6ENF71R5V, and RC0805FR-0771R5L—are Active products with ROHS3 compliance and identical electrical specifications. Selection between these parts is based on application-specific requirements:

CRCW080571R5FKEA (Vishay Dale) carries AEC-Q200 automotive qualification and exhibits the lowest seated height (0.020"), making it suitable for space-constrained automotive and high-reliability applications.

ERJ-6ENF71R5V (Panasonic) includes AEC-Q200 automotive qualification with the highest seated height (0.028"), appropriate for automotive applications where thermal dissipation or mechanical clearance is prioritized.

RC0805FR-0771R5L (YAGEO) provides moisture-resistant construction without automotive qualification, with moderate seated height (0.024"), suitable for general industrial and consumer applications.

RCS2012F71R5CS (Samsung) features anti-sulfur and moisture-resistant construction, optimized for environments with corrosive atmospheric conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW080571R5FKEA replace RCS2012F71R5CS in all applications?

A: Direct electrical and mechanical substitution is valid. CRCW080571R5FKEA includes AEC-Q200 automotive qualification, which RCS2012F71R5CS does not specify. If automotive qualification is required by design specification, CRCW080571R5FKEA is appropriate. If automotive qualification is not required, both parts are functionally equivalent.

Q: What is the significance of seated height differences among these parts?

A: Seated height variations (0.020" to 0.028") reflect manufacturing tolerances and construction differences. In standard PCB assembly with 0.062" nominal clearance, all parts are compatible. In space-constrained designs with height restrictions below 0.028", verify specific application requirements before selection.

Q: Are all substitute parts available in identical packaging formats?

A: RCS2012F71R5CS, CRCW080571R5FKEA, and ERJ-6ENF71R5V are supplied in Tape & Reel (TR) format. RC0805FR-0771R5L is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging format selection depends on assembly equipment compatibility and procurement volume requirements.

Q: Do these parts require different handling or storage procedures?

A: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard component storage at controlled temperature and humidity is sufficient for all four parts.

Q: Which substitute part is recommended for high-temperature applications?

A: All four parts share identical operating temperature range (-55°C ~ 155°C) and temperature coefficient (±100ppm/°C). Selection is not differentiated by thermal performance specifications.
