Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F64R9CS are qualified based on the following criteria:

Electrical Parameters: Resistance value of 64.9 Ohms, tolerance of ±1%, power rating of 0.125W (1/8W), and temperature coefficient of ±100ppm/°C must match exactly.

Mechanical Parameters: Package format must be 0805 (2012 Metric) with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Height variation is acceptable within manufacturing tolerances (0.020" to 0.028" seated height).

Composition & Construction: All substitutes utilize thick film technology with 2 terminations.

Environmental & Compliance: Operating temperature range of -55°C to 155°C, ROHS3 compliance, REACH unaffected status, and MSL 1 rating are required for all substitutes.

Additional Qualifications: Substitutes may include automotive-grade certifications (AEC-Q200) or enhanced environmental features (anti-sulfur, moisture-resistant) without affecting interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical requirements for direct replacement of the RCS2012F64R9CS. Selection among substitutes should be based on the following factors:

Product Availability: Inventory levels vary across manufacturers. ERJ-6ENF64R9V (Panasonic) offers the highest stock availability at 108,147 pieces. RC0805FR-0764R9L (YAGEO) provides 89,064 pieces. RMCF0805FT64R9 (Stackpole) and CRCW080564R9FKEA (Vishay Dale) offer 29,579 and 20,188 pieces respectively.

Compliance Certifications: CRCW080564R9FKEA, ERJ-6ENF64R9V, and RMCF0805FT64R9 carry automotive AEC-Q200 certification, suitable for automotive and high-reliability applications. RC0805FR-0764R9L and RCS2012F64R9CS provide standard industrial-grade compliance without automotive qualification.

Environmental Features: RCS2012F64R9CS and RC0805FR-0764R9L include moisture-resistant properties. RCS2012F64R9CS additionally features anti-sulfur protection. CRCW080564R9FKEA, ERJ-6ENF64R9V, and RMCF0805FT64R9 rely on automotive-grade construction for environmental robustness.

Physical Dimensions: All parts share identical footprint dimensions. Seated height varies minimally (0.020" to 0.028"), which does not affect PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW080564R9FKEA replace RCS2012F64R9CS directly?
