Key Parameters

Substitute Part Grouping Explanation

Substitution of the CRCW08054R02FNEA is determined by strict equivalence across the following critical parameters: resistance value (4.02 Ohms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), and compliance certifications (RoHS3, MSL 1). All identified substitute parts match these core electrical and mechanical specifications. Variations in temperature coefficient and maximum seated height are noted but do not prevent functional substitution within the specified operating conditions. Automotive AEC-Q200 rating is maintained across primary substitutes; one alternative (RC0805FR-074R02L) carries moisture-resistant designation instead of explicit AEC-Q200 rating but meets equivalent environmental performance requirements.

Parameter Comparison

Engineering Selection Recommendations

CRCW08054R02FKEA serves as an upgrade option within the Vishay Dale CRCW series, offering improved temperature coefficient stability (±100ppm/°C versus ±200ppm/°C) while maintaining identical electrical ratings and AEC-Q200 automotive compliance. This part is suitable for applications requiring tighter temperature stability.

RMCF0805FT4R02 from Stackpole Electronics Inc provides direct functional equivalence with AEC-Q200 rating and identical temperature coefficient. The seated height is 0.026" (0.65mm) compared to 0.020" (0.50mm) for the main part; this difference must be evaluated against PCB layout constraints and clearance requirements.

RC0805FR-074R02L from YAGEO is designated as manufacturer recommended and carries moisture-resistant thick film composition. While not explicitly rated AEC-Q200, it meets equivalent environmental performance standards. The seated height is 0.024" (0.60mm). This part is suitable for applications where moisture resistance is a design requirement.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical resistance, tolerance, power rating, and package specifications. Selection should be based on specific design requirements regarding temperature coefficient precision, physical height constraints, and environmental exposure conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW08054R02FKEA replace CRCW08054R02FNEA in all applications?

A: Yes. Both parts are manufactured by Vishay Dale, share identical electrical specifications (4.02 Ohms ±1%, 0.125W), package type (0805), and AEC-Q200 automotive rating. CRCW08054R02FKEA offers superior temperature coefficient (±100ppm/°C), making it suitable for applications with tighter thermal stability requirements.

Q: What is the significance of the seated height difference between RMCF0805FT4R02 and the main part?

A: RMCF0805FT4R02 has a maximum seated height of 0.026" (0.65mm) versus 0.020" (0.50mm) for CRCW08054R02FNEA. This 0.006" (0.15mm) difference must be verified against PCB design clearances, solder reflow profiles, and component placement constraints before substitution.

Q: Is RC0805FR-074R02L suitable for automotive applications?

A: RC0805FR-074R02L carries moisture-resistant designation rather than explicit AEC-Q200 rating. It meets equivalent environmental performance standards and is suitable for applications where moisture resistance is specified. Verify compliance with specific automotive qualification requirements for your application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (CRCW08054R02FKEA, RMCF0805FT4R02, and RC0805FR-074R02L) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably in PCB assembly?

A: Electrical interchangeability is confirmed across all parts. Physical interchangeability requires verification of seated height against PCB layout and clearance specifications. CRCW08054R02FNEA and CRCW08054R02FKEA have identical height (0.020"), while RMCF0805FT4R02 (0.026") and RC0805FR-074R02L (0.024") require clearance validation.
