Engineering Selection Recommendations

All three part numbers are active products with identical electrical and mechanical specifications. Selection between CRCW08052R55FNTA, RMCF0805FT2R55, and RC0805FR-072R55L depends on regulatory and compliance requirements:

CRCW08052R55FNTA (Vishay Dale) carries AEC-Q200 automotive qualification and is RoHS non-compliant with REACH Affected status. This part is suitable for automotive applications where AEC-Q200 certification is a primary requirement and RoHS compliance is not mandated.

RMCF0805FT2R55 (Stackpole Electronics) is ROHS3 compliant and REACH unaffected, with AEC-Q200 automotive qualification. This part supports applications requiring both automotive qualification and RoHS3 compliance. Seated height is 0.026" (0.65mm).

RC0805FR-072R55L (YAGEO) is ROHS3 compliant and REACH unaffected, with moisture-resistant thick film construction. This part supports applications requiring RoHS3 compliance without automotive qualification. Seated height is 0.024" (0.60mm).

Physical height variations (0.50mm, 0.60mm, 0.65mm) are within standard PCB assembly tolerances and do not affect electrical performance or thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT2R55 or RC0805FR-072R55L be used as direct replacements for CRCW08052R55FNTA?

A: Yes, both parts are electrically and mechanically compatible. All three parts share identical resistance (2.55 Ohms), tolerance (±1%), power rating (0.125W), package (0805), composition (thick film), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C). Seated height differences (0.50mm, 0.60mm, 0.65mm) are within standard assembly tolerances.

Q: What is the difference in compliance between these parts?

A: CRCW08052R55FNTA is RoHS non-compliant and REACH affected. RMCF0805FT2R55 and RC0805FR-072R55L are both ROHS3 compliant and REACH unaffected. Selection depends on whether your application or region requires RoHS3 compliance.

Q: Does AEC-Q200 certification matter for my application?

A: AEC-Q200 certification applies to automotive-grade components. CRCW08052R55FNTA and RMCF0805FT2R55 both carry AEC-Q200 qualification. RC0805FR-072R55L does not list AEC-Q200 certification. Use AEC-Q200 qualified parts only if your application requires automotive-grade reliability standards.

Q: Are there inventory differences between these parts?

A: Yes. CRCW08052R55FNTA has 792 pieces in stock, RMCF0805FT2R55 has 6942 pieces, and RC0805FR-072R55L has 4692 pieces. Availability may influence procurement decisions for high-volume production.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 (Moisture Sensitivity Level 1) with unlimited rating indicates these components have no moisture sensitivity restrictions. They can be stored and handled without special moisture control measures and have unlimited shelf life under normal conditions.

Q: Are the physical dimensions identical across all three parts?

A: Length and width are identical (0.079" x 0.049" / 2.00mm x 1.25mm). Seated height varies slightly: CRCW08052R55FNTA is 0.020" (0.50mm), RC0805FR-072R55L is 0.024" (0.60mm), and RMCF0805FT2R55 is 0.026" (0.65mm). These variations are within standard PCB assembly tolerances and do not affect circuit performance.
