Parameter Comparison

Engineering Selection Recommendations

Both the CRCW08051R21FNEB and RMCF0805FT1R21 are active production parts with identical electrical specifications and automotive AEC-Q200 compliance. Selection between these parts is based on availability, lead time, and procurement requirements. The RMCF0805FT1R21 has a maximum seated height of 0.026" (0.65mm) compared to 0.020" (0.50mm) for the CRCW08051R21FNEB. This height difference must be evaluated against PCB layout constraints and clearance requirements in the target application. Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT1R21 be used as a direct replacement for CRCW08051R21FNEB?

A: Yes. Both parts share identical electrical specifications (1.21 Ohms ±1%, 0.125W), package dimensions (0805 / 2012 Metric), composition (Thick Film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive AEC-Q200 rating. The maximum seated height differs by 0.006" (0.15mm), which must be verified against PCB clearance requirements.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Q: What is the significance of the height difference?

A: The RMCF0805FT1R21 has a maximum seated height of 0.026" (0.65mm) versus 0.020" (0.50mm) for the CRCW08051R21FNEB. In applications with tight vertical clearance constraints, this 0.006" (0.15mm) difference must be evaluated during design review.

Q: Are both parts suitable for automotive applications?
