Equivalent & Substitute Parts for CRCW080563R4FKEAC

Part Overview

The CRCW080563R4FKEAC is a 63.4 Ohm ±1% 1/8W chip resistor in 0805 (2012 Metric) package manufactured by Vishay Dale. This thick film resistor is designed for general-purpose applications requiring precision resistance values with tight tolerance specifications. The part is currently active in production. Substitute parts may be required due to supply chain constraints, regional availability, or specific application requirements such as enhanced moisture resistance or alternative packaging formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW080563R4FKEAC is determined by strict equivalence across the following parameters:

• Resistance value: 63.4 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria. Variations in physical dimensions (height-seated maximum), packaging format (Tape & Reel vs. Cut Tape), and specific features (such as moisture resistance enhancement) do not affect functional substitutability but may influence procurement and assembly considerations.

Parameter Comparison

Engineering Selection Recommendations

The CRCW080563R4FKEAC (Vishay Dale) remains the primary specification part with active product status and standard packaging in Tape & Reel format.

The CR0805-FX-63R4ELF (Bourns Inc.) is functionally equivalent with active product status. This part features moisture-resistant thick film composition and is suitable for applications requiring enhanced environmental protection. Physical dimensions are identical to the primary part (0.024" maximum seated height). Packaging is available in Tape & Reel format.

The MCR10ERTF63R4 (Rohm Semiconductor) is functionally equivalent but carries discontinued status at DiGi Electronics. This part is available in Cut Tape and Digi-Reel packaging formats. The maximum seated height is 0.026" (0.65mm), which is 0.002" greater than the primary part. This dimensional difference may require verification for applications with strict height constraints or high-density PCB layouts.

All three parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and identical electrical specifications. Selection should prioritize active product status and availability requirements.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTF63R4 be used as a direct replacement for CRCW080563R4FKEAC?

A: Yes, MCR10ERTF63R4 is electrically equivalent. However, the maximum seated height is 0.026" compared to 0.024" for the primary part. Applications with height-constrained PCB layouts should verify clearance before substitution.

Q: What is the difference between the Bourns CR0805-FX-63R4ELF and the Vishay CRCW080563R4FKEAC?

A: Both parts are electrically and dimensionally equivalent. The CR0805-FX-63R4ELF features moisture-resistant thick film composition, providing enhanced environmental protection. Both maintain active product status.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three parts (CRCW080563R4FKEAC, MCR10ERTF63R4, and CR0805-FX-63R4ELF) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats do not affect electrical performance. Selection should be based on assembly equipment compatibility and procurement requirements.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: The temperature coefficient indicates resistance value change per degree Celsius. At ±100ppm/°C, a 63.4 Ohm resistor will experience approximately 0.0063 Ohm change per degree Celsius across the -55°C to 155°C operating range. This specification is identical across all substitute parts.

Q: Can these parts be used interchangeably in high-frequency applications?

A: Electrical specifications provided do not include frequency-dependent parameters. Application-specific frequency requirements should be evaluated independently.
