Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08051R80FNEC is determined by strict equivalence across the following parameters:

• Resistance value: 1.8 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The RMCF0805FT1R80 manufactured by Stackpole Electronics Inc meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the CRCW08051R80FNEC and RMCF0805FT1R80 are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts may be based on availability, lead time, or supply chain requirements. The RMCF0805FT1R80 offers higher inventory availability (13679 pieces) compared to the CRCW08051R80FNEC (1015 pieces). The maximum seated height difference of 0.006" (0.15mm) between the two parts is within typical PCB assembly tolerances for 0805 packages and does not affect electrical performance or mechanical fit in standard applications.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT1R80 be used as a direct replacement for CRCW08051R80FNEC?

A: Yes. Both parts share identical electrical specifications (1.8 Ohms ±1%, 0.125W), package dimensions (0805 / 2012 Metric), temperature characteristics (±200ppm/°C, -55°C to 155°C), and automotive qualification (AEC-Q200). The seated height difference of 0.006" is within standard PCB assembly tolerances.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry AEC-Q200 automotive qualification. Moisture sensitivity level is identical at MSL 1 (Unlimited).

Q: What is the significance of the 0805 package designation?

A: The 0805 package (2012 Metric) is a standardized surface-mount resistor size measuring 0.079" x 0.049" (2.00mm x 1.25mm). Both substitute parts use this identical package, ensuring mechanical and electrical compatibility on PCBs designed for 0805 resistors.

Q: Does the temperature coefficient affect substitution eligibility?

A: No. Both parts have identical temperature coefficients of ±200ppm/°C and identical operating temperature ranges of -55°C to 155°C, ensuring equivalent performance across all specified operating conditions.

Q: Are packaging formats interchangeable?

A: Yes. Both parts are supplied in Tape & Reel (TR) format, which is standard for automated PCB assembly processes.
