Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF0805FR-072M7L is determined by strict equivalence across the following critical parameters:

• Resistance Value: 2.7 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)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria. Variations in secondary features such as anti-sulfur coating or specific automotive certifications do not disqualify substitution when core electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AF0805FR-072M7L, RC0805FR-072M7L, and CRCW08052M70FKEA—are functionally equivalent for applications requiring a 2.7 MOhms ±1% 1/8W 0805 thick film resistor. Selection among these parts should be based on:

Compliance and Certifications: The AF0805FR-072M7L and CRCW08052M70FKEA both carry AEC-Q200 automotive qualification. The RC0805FR-072M7L does not list AEC-Q200 certification but meets all core electrical and mechanical specifications. For automotive or high-reliability applications requiring AEC-Q200 compliance, AF0805FR-072M7L or CRCW08052M70FKEA are appropriate selections.

Feature Differentiation: The AF0805FR-072M7L includes anti-sulfur coating, suitable for environments with corrosive exposure. The RC0805FR-072M7L features moisture-resistant construction. The CRCW08052M70FKEA carries AEC-Q200 automotive qualification. These feature differences do not affect electrical substitution but may influence selection based on application environment.

Physical Dimensions: The CRCW08052M70FKEA has a maximum seated height of 0.020" (0.50mm), compared to 0.024" (0.60mm) for both YAGEO parts. This minor difference is within standard PCB design tolerances for 0805 packages and does not restrict substitution.

Inventory and Availability: RC0805FR-072M7L has the highest inventory (45,869 pieces), followed by CRCW08052M70FKEA (64,910 pieces), and AF0805FR-072M7L (1,137 pieces). Procurement decisions may consider availability and lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-072M7L replace AF0805FR-072M7L in automotive applications?

A: RC0805FR-072M7L meets all core electrical and mechanical specifications for direct substitution. However, it does not carry AEC-Q200 automotive certification. For applications requiring AEC-Q200 compliance, AF0805FR-072M7L or CRCW08052M70FKEA are the appropriate selections.

Q: What is the significance of the anti-sulfur coating on AF0805FR-072M7L?

A: The anti-sulfur coating provides protection against corrosive sulfur-containing environments. This feature is specific to the AF series and is not present on RC0805FR-072M7L or CRCW08052M70FKEA. Selection should be based on environmental exposure requirements.

Q: Are there physical compatibility concerns when substituting between these parts?

A: All three parts use the 0805 (2012 Metric) package with identical length and width dimensions (0.079" x 0.049"). The CRCW08052M70FKEA has a slightly lower maximum seated height (0.020" vs. 0.024"), which does not create compatibility issues for standard PCB designs.

Q: Do all substitute parts meet RoHS and REACH requirements?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What is the difference between the AF and RC series from YAGEO?

A: The AF series includes anti-sulfur coating and AEC-Q200 automotive qualification. The RC_L series features moisture-resistant construction. Both series meet identical electrical specifications for this 2.7 MOhms ±1% 1/8W resistor value.

Q: Can CRCW08052M70FKEA be used as a direct replacement in all applications?

A: CRCW08052M70FKEA is electrically and mechanically equivalent to AF0805FR-072M7L. Both carry AEC-Q200 certification. The primary difference is manufacturer (Vishay Dale vs. YAGEO) and the absence of anti-sulfur coating on the Vishay part. For applications not requiring anti-sulfur protection, CRCW08052M70FKEA is a valid substitute.
