Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08058R45FNTA is determined by strict equivalence across the following parameters:

• Resistance value: 8.45 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W, 1/8W (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The RC0805FR-078R45L from YAGEO meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the CRCW08058R45FNTA and RC0805FR-078R45L are active production components with identical electrical specifications and package dimensions. Selection between these parts should be based on compliance and certification requirements specific to the application.

The CRCW08058R45FNTA carries AEC-Q200 automotive qualification and is RoHS non-compliant. The RC0805FR-078R45L is ROHS3 compliant and features moisture-resistant construction. The maximum seated height differs by 0.004" (0.10mm), which may be relevant for applications with strict height constraints.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-078R45L replace CRCW08058R45FNTA in automotive applications?

A: Both parts meet the same electrical specifications and package requirements. However, the CRCW08058R45FNTA carries AEC-Q200 qualification specific to automotive use. Application requirements should determine whether AEC-Q200 certification is mandatory.

Q: What is the difference in height between these two parts?

A: The CRCW08058R45FNTA has a maximum seated height of 0.020" (0.50mm), while the RC0805FR-078R45L measures 0.024" (0.60mm). This 0.004" (0.10mm) difference may impact PCB assembly in space-constrained designs.

Q: Are the resistance and tolerance values identical?

A: Yes. Both parts are specified at 8.45 Ohms ±1% with identical temperature coefficients of ±200ppm/°C and operating temperature ranges of -55°C to 155°C.

Q: What does RoHS compliance mean for component selection?

A: RoHS3 compliance indicates the RC0805FR-078R45L meets restrictions on hazardous substances. The CRCW08058R45FNTA is RoHS non-compliant. Regulatory requirements for the end application determine which compliance status is necessary.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both components use identical 0805 (2012 Metric) package specifications with 2 terminations and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard SMD assembly processes.
