AHA50AJB-22R Equivalent & Substitute Parts

Part Overview

The AHA50AJB-22R is a 22 Ohms ±5% 50W wirewound chassis mount resistor manufactured by YAGEO. This component is designed for high-power applications requiring reliable thermal dissipation through aluminum housing with flanged mounting. The part is currently active in production with 750 units in stock. Substitute parts are identified for applications requiring alternative sourcing, improved specifications, or packaging format changes while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AHA50AJB-22R is determined by the following mandatory parameters:

• Resistance value: 22 Ohms (exact match required)
• Power rating: 50W (exact match required)
• Composition: Wirewound (exact match required)
• Mounting feature: Flanges (exact match required)
• Lead style: Solder Lugs (exact match required)
• Housing type: Aluminum (exact match required)
• Package/Case: Axial, Box (exact match required)

All identified substitute parts meet these core requirements. Variations in tolerance, temperature coefficient, operating temperature range, and packaging format (Bulk vs. Tray) are permitted within the scope of substitution, as these parameters do not affect the primary functional role of the component in its intended application.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

HSA5022RJ and THS5022RJ are functionally equivalent to the AHA50AJB-22R with identical tolerance (±5%) and power rating. Both are manufactured by TE Connectivity. HSA5022RJ is available in Bulk packaging with 2129 units in stock. THS5022RJ is available in Tray packaging with 1042 units in stock. Both parts feature improved temperature coefficient (±50ppm/°C vs. ±200ppm/°C) but operate within a reduced temperature range (-55°C ~ 200°C vs. -55°C ~ 250°C).

RH05022R00FE02 is manufactured by Vishay Dale and offers superior tolerance specification (±1% vs. ±5%) with the lowest temperature coefficient (±20ppm/°C). This part maintains the full operating temperature range (-55°C ~ 250°C) and includes moisture-resistant features. RH05022R00FE02 is available in Bulk packaging with 897 units in stock.

Selection should be based on application requirements for tolerance precision, temperature stability, operating temperature limits, and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can HSA5022RJ or THS5022RJ be used as direct replacements for AHA50AJB-22R?

A: Yes. Both parts meet all mandatory substitution criteria: 22 Ohms resistance, ±5% tolerance, 50W power rating, wirewound composition, flanged mounting, solder lugs, and aluminum housing. The primary difference is the reduced maximum operating temperature (200°C vs. 250°C). Verify application temperature requirements before substitution.

Q: What is the advantage of RH05022R00FE02 over the original AHA50AJB-22R?

A: RH05022R00FE02 provides tighter tolerance (±1% vs. ±5%) and superior temperature stability (±20ppm/°C vs. ±200ppm/°C). It maintains the full operating temperature range and includes moisture-resistant features. These specifications are beneficial for precision applications requiring stable resistance values across temperature variations.

Q: Are there packaging format differences between substitute parts?

A: Yes. AHA50AJB-22R, HSA5022RJ, and RH05022R00FE02 are supplied in Bulk packaging. THS5022RJ is supplied in Tray packaging. Packaging format does not affect electrical or mechanical compatibility but may influence procurement and handling procedures.

Q: Do all substitute parts meet current compliance standards?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements equivalent to the original AHA50AJB-22R.

Q: What are the physical dimension variations among substitute parts?

A: Dimensional variations are minor. AHA50AJB-22R and RH05022R00FE02 have nearly identical dimensions (approximately 50mm L x 29mm W x 16.5mm H). HSA5022RJ and THS5022RJ are slightly larger (51mm L x 30mm W x 17mm H). Verify mounting space availability in your application before substitution.
