AHA50AFB-22R Equivalent & Substitute Parts

Part Overview

The AHA50AFB-22R is a 22 Ohms ±1% 50W wirewound chassis mount resistor manufactured by YAGEO. This component is designed for high-power applications requiring precision resistance with stable thermal performance across industrial temperature ranges. The part maintains Active product status with full RoHS3 compliance and REACH unaffected certification. Substitute parts are identified to provide alternative sourcing options when primary inventory is unavailable or when design requirements permit equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AHA50AFB-22R is determined by strict equivalence across the following critical parameters:

• Resistance value: 22 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 50W (exact match required)
• Composition: Wirewound (exact match required)
• Operating temperature range: -55°C ~ 250°C (exact match required)
• Mounting feature: Flanges (exact match required)
• Lead style: Solder Lugs (exact match required)
• Housing type: Aluminum (exact match required)
• Regulatory compliance: RoHS3 Compliant (exact match required)

The substitute part RH05022R00FE02 manufactured by Vishay Dale meets all mandatory electrical and mechanical parameters. Physical dimensions remain within acceptable tolerance (49.99mm L x 28.96mm W vs. 50.00mm L x 29.00mm W), and seated height variation (15.87mm vs. 16.50mm) falls within standard PCB layout margins for chassis mount applications.

Parameter Comparison

Engineering Selection Recommendations

Both AHA50AFB-22R and RH05022R00FE02 are Active status components with full regulatory compliance. Selection between these parts should be based on availability and supply chain requirements. The RH05022R00FE02 exhibits superior temperature coefficient performance (±20ppm/°C vs. ±200ppm/°C), which may provide enhanced stability in applications with strict thermal drift specifications. Both parts satisfy RoHS3 and REACH compliance requirements for regulated markets. Physical dimensions are interchangeable within standard PCB layout tolerances for chassis mount applications.

Frequently Asked Questions (FAQ)

Q: Can RH05022R00FE02 be used as a direct replacement for AHA50AFB-22R?

A: Yes. Both parts meet identical electrical specifications (22 Ohms ±1% 50W wirewound), operate across the same temperature range (-55°C ~ 250°C), and share identical mounting features (flanges with solder lugs). Physical dimensions are equivalent within standard manufacturing tolerances.

Q: What is the significance of the temperature coefficient difference?

A: The RH05022R00FE02 exhibits a temperature coefficient of ±20ppm/°C compared to ±200ppm/°C for the AHA50AFB-22R. This indicates lower resistance drift across temperature variations, which may be advantageous in precision measurement or high-stability applications. Both values remain within acceptable ranges for standard industrial applications.

Q: Are there any packaging or mounting differences?

A: Both parts use identical packaging (Axial, Box) and mounting configuration (flanges with solder lugs). Seated height variation (15.87mm vs. 16.50mm) is within standard PCB layout margins and does not affect mechanical compatibility.

Q: Do both parts meet regulatory requirements?

A: Yes. Both AHA50AFB-22R and RH05022R00FE02 are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronics manufacturing in regulated markets.

Q: What factors should determine part selection?

A: Selection should be based on current inventory availability, supply chain lead times, and application-specific thermal stability requirements. Both parts are functionally equivalent for standard 50W resistive load applications.
