CRCW080573R2FKEAC Equivalent & Substitute Parts

Part Overview

The CRCW080573R2FKEAC is a 73.2 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 resistive elements with tight tolerance specifications. The part is currently active in production with 1045 units in stock. Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain constraints require alternative sourcing, or when design flexibility permits equivalent components from other manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW080573R2FKEAC is determined by strict equivalence across the following parameters:

• Resistance value: 73.2 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 or wider range acceptable)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

The MCR10ERTF73R2 from Rohm Semiconductor meets all substitution criteria and is electrically and mechanically equivalent to the CRCW080573R2FKEAC.

Parameter Comparison

Engineering Selection Recommendations

The MCR10ERTF73R2 is a direct functional equivalent to the CRCW080573R2FKEAC. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The MCR10ERTF73R2 is currently discontinued at DiGi Electronics, whereas the CRCW080573R2FKEAC remains in active production with adequate inventory. Selection between these parts should be based on availability and supply chain requirements. The maximum seated height difference of 0.002" (0.05mm) between the two parts is negligible for standard PCB assembly applications and does not affect functional performance or board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MCR10ERTF73R2 be used as a direct replacement for the CRCW080573R2FKEAC?

A: Yes. Both parts share identical electrical specifications (73.2 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C operating range) and are packaged in the same 0805 (2012 Metric) form factor. Both are ROHS3 compliant with MSL 1 rating.

Q: Are there any physical differences between these parts?

A: The maximum seated height differs by 0.002" (0.05mm): the CRCW080573R2FKEAC is 0.024" (0.60mm) maximum, while the MCR10ERTF73R2 is 0.026" (0.65mm) maximum. This difference is within standard PCB assembly tolerances and does not affect board-level compatibility.

Q: What packaging formats are available for these parts?

A: The CRCW080573R2FKEAC is supplied in Tape & Reel (TR) format. The MCR10ERTF73R2 is available in Cut Tape (CT) and Digi-Reel® formats. Packaging format selection depends on assembly process requirements and order quantities.

Q: Are both parts suitable for high-reliability applications?

A: Both parts meet ROHS3 compliance and have MSL 1 (unlimited moisture sensitivity level) ratings, indicating suitability for standard commercial and industrial applications. Specific reliability requirements should be evaluated against application-level specifications.

Q: What is the current availability status of these parts?

A: The CRCW080573R2FKEAC is active in production with 1045 units in stock. The MCR10ERTF73R2 is discontinued at DiGi Electronics. Availability should be confirmed with current distributors before design finalization.
