Substitute Part Grouping Explanation

Substitution eligibility for the CRCW080573K2FKEAC is determined by strict equivalence across the following parameters:

• Resistance value: 73.2 kOhms (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 ~ 155°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

The two qualified substitute parts meet all electrical and mechanical parameters. Differences in features (moisture resistance, automotive qualification) and inventory levels do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active production components with ROHS3 compliance and identical core electrical specifications. Selection between them is based on application-specific requirements and availability:

The CRCW080573K2FKEAC (Vishay Dale) serves as the primary reference part with standard thick film construction suitable for general-purpose applications.

The CR0805-FX-7322ELF (Bourns Inc.) provides moisture-resistant thick film construction and represents the highest inventory availability (25022 pieces), making it suitable for applications requiring enhanced environmental protection or where supply continuity is prioritized.

The RMCF0805FT73K2 (Stackpole Electronics) carries AEC-Q200 automotive qualification, making it the appropriate selection for automotive and mission-critical applications requiring automotive-grade component certification.

Frequently Asked Questions (FAQ)

Q: Can CR0805-FX-7322ELF be used as a direct replacement for CRCW080573K2FKEAC?

A: Yes. Both parts meet identical electrical specifications (73.2 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C operating range) and share the same 0805 package footprint. The moisture-resistant feature of the Bourns part provides additional environmental protection without affecting electrical interchangeability.

Q: What is the difference between the RMCF0805FT73K2 and the other two parts?

A: The RMCF0805FT73K2 carries AEC-Q200 automotive qualification. All three parts are electrically and mechanically equivalent. The automotive qualification is relevant only for applications requiring automotive-grade component certification.

Q: Are there any physical dimension differences between these parts?

A: The CRCW080573K2FKEAC and CR0805-FX-7322ELF have identical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm). The RMCF0805FT73K2 has a maximum seated height of 0.026" (0.65mm) compared to 0.024" (0.60mm) for the other two parts. This minor difference does not affect PCB layout compatibility for standard 0805 package designs.

Q: Which part should be selected for high-volume production?

A: The CR0805-FX-7322ELF offers the highest inventory level (25022 pieces) and is suitable for high-volume applications without automotive requirements. For automotive applications, the RMCF0805FT73K2 is the appropriate selection despite lower inventory.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant with moisture sensitivity level 1 (unlimited), making them suitable for standard manufacturing and storage conditions.
