AF2010JK-072ML Equivalent & Substitute Parts

Part Overview

The AF2010JK-072ML is a 2 MOhms ±5% 0.75W chip resistor in 2010 (5025 Metric) package manufactured by YAGEO. This thick film resistor features anti-sulfur coating and automotive AEC-Q200 qualification, designed for applications requiring high resistance values with moderate power dissipation in compact form factors. The part is currently active in production with 986 units in stock. Substitute parts may be required due to inventory constraints, design optimization for tighter tolerance requirements, or alternative manufacturer preferences while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AF2010JK-072ML is determined by strict equivalence in the following parameters:

• Resistance Value: Must be 2 MOhms (no deviation)
• Power Rating: Must be 0.75W minimum
• Package: Must be 2010 (5025 Metric) with identical footprint dimensions
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• Temperature Coefficient: Must be ±100ppm/°C or better
• Composition: Thick film construction
• Compliance: RoHS3 and REACH requirements must be met

Tolerance may vary (±5% to ±1%) as tighter tolerance is a functional upgrade. Automotive AEC-Q200 qualification is a feature enhancement, not a requirement for substitution. Moisture resistance features do not affect substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both RC2010FK-072ML and CRCW20102M00FKEF are electrically and mechanically compatible with AF2010JK-072ML for standard applications. Selection should be based on the following criteria:

RC2010FK-072ML (YAGEO): Maintains manufacturer continuity with the original part. Offers tighter ±1% tolerance specification. Provides moisture-resistant thick film construction. Suitable for applications where YAGEO supply chain preference is established and AEC-Q200 qualification is not required.

CRCW20102M00FKEF (Vishay Dale): Provides automotive AEC-Q200 qualification matching the original part's automotive-grade specification. Offers tighter ±1% tolerance. Introduces alternative manufacturer sourcing for supply chain diversification. Maximum seated height is 0.028" (0.70mm) versus 0.026" (0.65mm) for the original; verify PCB clearance in space-constrained applications.

Both substitutes maintain full RoHS3 and REACH compliance. All three parts operate across the identical -55°C ~ 155°C temperature range with ±100ppm/°C temperature coefficient.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-072ML replace AF2010JK-072ML in automotive applications? A: RC2010FK-072ML is electrically and mechanically compatible. However, it lacks AEC-Q200 automotive qualification. Use only if your application does not mandate automotive-grade certification.

Q: Is CRCW20102M00FKEF a direct drop-in replacement? A: CRCW20102M00FKEF is electrically equivalent and maintains AEC-Q200 qualification. The seated height is 0.028" (0.70mm) compared to 0.026" (0.65mm) for AF2010JK-072ML. Verify PCB layout clearance before substitution.

Q: Does tolerance difference affect substitutability? A: Both substitutes offer ±1% tolerance, which is tighter than the original ±5%. This represents improved accuracy and is functionally compatible. Applications designed for ±5% tolerance will operate within specification with ±1% parts.

Q: Are all three parts RoHS3 compliant? A: Yes. AF2010JK-072ML, RC2010FK-072ML, and CRCW20102M00FKEF are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What is the key difference between the two substitutes? A: RC2010FK-072ML maintains YAGEO manufacturer continuity without AEC-Q200. CRCW20102M00FKEF provides Vishay Dale sourcing with AEC-Q200 automotive qualification and slightly increased seated height.

Q: Can I use these substitutes interchangeably on the same PCB? A: Yes, all three parts share identical 2010 (5025 Metric) footprints and electrical specifications. The 0.002" (0.05mm) height difference for CRCW20102M00FKEF is negligible for most applications but should be verified in space-constrained designs.
