Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08051R50FNEA is determined by strict equivalence across the following parameters: resistance value (1.5 Ohms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), and compliance certifications (AEC-Q200, ROHS3). All identified substitute parts match these core electrical and mechanical specifications. Variations in temperature coefficient, height-seated maximum, and packaging format (Tape & Reel versus Cut Tape) are secondary characteristics that do not affect functional interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

CRCW08051R50FKEA (Vishay Dale) is an upgrade substitute with identical electrical specifications and improved temperature coefficient (±100ppm/°C versus ±200ppm/°C), maintaining AEC-Q200 automotive qualification and ROHS3 compliance.

RMCF0805FT1R50 (Stackpole Electronics Inc) is a direct manufacturer alternative with equivalent electrical and thermal specifications, AEC-Q200 rating, and ROHS3 compliance. Height-seated maximum is 0.026" (0.65mm), which is within acceptable mechanical tolerance for 0805 package applications.

AC0805FR-071R5L (YAGEO) is a manufacturer-recommended substitute with moisture-resistant thick film composition, AEC-Q200 automotive qualification, and ROHS3 compliance. Height-seated maximum is 0.024" (0.60mm).

RC0805FR-071R5L (YAGEO) is a manufacturer-recommended substitute available in Cut Tape and Digi-Reel packaging formats. This part does not carry AEC-Q200 automotive rating and features moisture-resistant composition. Selection of this part is appropriate for non-automotive applications or where automotive qualification is not required. ROHS3 compliance is maintained.

Frequently Asked Questions (FAQ)

Q: Can CRCW08051R50FKEA replace CRCW08051R50FNEA in automotive applications? A: Yes. Both parts are manufactured by Vishay Dale, share identical resistance, tolerance, power rating, package, and AEC-Q200 automotive qualification. CRCW08051R50FKEA features improved temperature coefficient performance (±100ppm/°C).

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging is supplied on continuous carrier tape for automated pick-and-place assembly. Cut Tape (CT) and Digi-Reel packaging are supplied in shorter tape segments. Selection depends on assembly equipment compatibility and order quantity requirements.

Q: Is RC0805FR-071R5L suitable for automotive applications? A: RC0805FR-071R5L does not carry AEC-Q200 automotive qualification. This part is suitable for consumer and industrial applications where automotive standards are not required. For automotive designs, select CRCW08051R50FNEA, CRCW08051R50FKEA, RMCF0805FT1R50, or AC0805FR-071R5L.

Q: What does temperature coefficient mean in resistor selection? A: Temperature coefficient (ppm/°C) specifies the fractional change in resistance per degree Celsius. CRCW08051R50FKEA has ±100ppm/°C, indicating tighter resistance stability across temperature variations compared to parts with ±200ppm/°C. Selection depends on circuit precision requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts meet ROHS3 compliance requirements, confirming restriction of hazardous substances in accordance with applicable regulations.

Q: Can height differences affect PCB assembly? A: Height-seated maximum values range from 0.020" to 0.026" (0.50mm to 0.65mm). These variations are within standard 0805 package tolerance and do not affect PCB assembly compatibility. Verify clearance requirements for specific board designs if space constraints exist.
