CRCW0805475RCHEAP Equivalent & Substitute Parts

Part Overview

The CRCW0805475RCHEAP is a 475 Ohm ±0.25% 0.125W chip resistor in 0805 (2012 Metric) package manufactured by Vishay Dale. This thick film automotive-grade resistor meets AEC-Q200 qualification standards and operates across -55°C to 155°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring this specific resistance value and package configuration.

Substitute Part Grouping Explanation

Substitution for the CRCW0805475RCHEAP is determined by strict equivalence across the following critical parameters:

• Resistance value: 475 Ohms (exact match required)
• Package type: 0805 (2012 Metric) form factor
• Power rating: 0.125W minimum
• Operating temperature range: -55°C to 155°C minimum
• Automotive qualification: AEC-Q200 compliance
• RoHS compliance: ROHS3 Compliant

The ERA-6AEB4750V from Panasonic Electronic Components qualifies as a direct substitute. While it features improved tolerance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), these represent performance enhancements rather than deviations. Both parts maintain identical resistance, power rating, package configuration, operating temperature range, and automotive certification requirements.

Parameter Comparison

Engineering Selection Recommendations

The ERA-6AEB4750V serves as the primary substitute for the obsolete CRCW0805475RCHEAP. Both components maintain full compliance with AEC-Q200 automotive qualification and ROHS3 regulatory requirements. The Panasonic part offers superior tolerance specification (±0.1% versus ±0.25%) and improved temperature stability (±25ppm/°C versus ±50ppm/°C), making it functionally equivalent with enhanced performance characteristics. Active product status of the ERA-6AEB4750V ensures continued availability for production and field replacement applications.

The maximum seated height difference of 0.004" (0.10mm) between the two parts remains within typical PCB assembly tolerances and does not present mechanical compatibility concerns for standard 0805 footprints.

Frequently Asked Questions (FAQ)

Q: Can the ERA-6AEB4750V directly replace the CRCW0805475RCHEAP in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package configuration, operating temperature range, and automotive certification. The ERA-6AEB4750V is electrically and mechanically compatible with the original part's 0805 footprint.

Q: What is the significance of the tolerance difference between ±0.25% and ±0.1%?

A: The ERA-6AEB4750V provides tighter tolerance specification, meaning its actual resistance value will remain closer to the nominal 475 Ohm value across production batches. This represents an improvement over the original part's tolerance and does not create substitution barriers.

Q: Why does the ERA-6AEB4750V have a higher maximum seated height?

A: The ERA-6AEB4750V measures 0.024" (0.60mm) maximum height versus 0.020" (0.50mm) for the original part. This 0.004" (0.10mm) difference falls within standard PCB assembly clearance specifications and does not affect compatibility with 0805 component footprints.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the CRCW0805475RCHEAP and ERA-6AEB4750V carry AEC-Q200 automotive qualification, confirming suitability for automotive-grade circuit applications across the specified operating temperature range of -55°C to 155°C.

Q: What is the difference between thick film and thin film composition?

A: The original part uses thick film technology while the substitute uses thin film technology. Both technologies achieve the required electrical specifications for this application. Thin film composition in the ERA-6AEB4750V contributes to its improved tolerance and temperature coefficient performance.
