Substitute Part Grouping Explanation

Substitution of the RC2012F8454CS is valid when the following parameters are maintained:

• Resistance Value: 8.45 MOhms (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)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The CRCW08058M45FKEA from Vishay Dale meets all these criteria and qualifies as a direct substitute. Physical dimensions remain within acceptable tolerances for PCB assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RC2012F8454CS and CRCW08058M45FKEA are active production components with identical electrical and thermal specifications. Selection between these parts is based on:

Product Availability: The CRCW08058M45FKEA has higher inventory availability (7451 pieces) compared to the RC2012F8454CS (687 pieces).

Compliance Certifications: The CRCW08058M45FKEA carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. Both parts maintain ROHS3 compliance and REACH unaffected status.

Physical Dimensions: The CRCW08058M45FKEA has a lower seated height (0.020" vs 0.026"), which may provide marginal advantages in space-constrained PCB layouts while maintaining full mechanical compatibility with 0805 footprints.

Series Designation: RC series (Samsung) and CRCW series (Vishay Dale) represent different manufacturer product lines with equivalent performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the CRCW08058M45FKEA replace the RC2012F8454CS in existing designs?

A: Yes. Both components share identical resistance value (8.45 MOhms), tolerance (±1%), power rating (0.125W), package (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH unaffected). The 0805 footprint is standardized, and the physical dimension differences are within PCB assembly tolerances.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact matching of: resistance value, tolerance, power rating, package type, composition, temperature coefficient, operating temperature range, moisture sensitivity level, and RoHS compliance status. Deviation in any of these parameters disqualifies a part as a direct substitute.

Q: Does the height difference between these parts affect PCB assembly?

A: No. The CRCW08058M45FKEA seated height of 0.020" (0.50mm) is lower than the RC2012F8454CS at 0.026" (0.66mm). Both values are within standard 0805 package specifications and do not affect PCB assembly compatibility or solder reflow processes.

Q: Are there any application restrictions based on the AEC-Q200 rating of the substitute?

A: The AEC-Q200 automotive qualification of the CRCW08058M45FKEA indicates enhanced reliability testing and is suitable for automotive applications. This certification does not restrict use in non-automotive applications. The RC2012F8454CS lacks this specific automotive qualification but remains suitable for general industrial and commercial applications.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this rating, eliminating moisture-related supply chain considerations.
