HS50 22R J Equivalent & Substitute Parts

Part Overview

The HS50 22R J is a 22 Ohms ±5% 50W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is an active product with 975 units in stock. The HS50 22R J features aluminum housing with flanged mounting and solder lug termination, designed for applications requiring high power dissipation in a compact form factor. Equivalent and substitute parts are identified based on matching resistance value, tolerance, composition, and mechanical compatibility while accounting for power rating variations and manufacturer options.

Substitute Part Grouping Explanation

Substitution of the HS50 22R J is determined by the following critical parameters: resistance value (22 Ohms), tolerance (±5%), wirewound composition, aluminum housing, flanged mounting, and solder lug termination. Power rating is the primary variable distinguishing substitute groups. The HS25 22R J and HS25 22R F are lower-power alternatives rated at 25W, suitable for applications with reduced thermal requirements. The HS50 22R J (ARCOL manufacturer variant) maintains identical electrical and mechanical specifications to the primary part. All substitutes share the same resistance, temperature coefficient, housing material, and mounting interface, ensuring mechanical and electrical compatibility within their respective power ratings.

Engineering Selection Recommendations

The HS50 22R J (ARCOL) is a direct equivalent to the primary HS50 22R J (Ohmite) part, offering identical electrical and mechanical specifications with higher inventory availability (1150 units). Both maintain ROHS3 compliance and are suitable for applications requiring 50W power dissipation.

The HS25 22R J (ARCOL) and HS25 22R F (Ohmite) are lower-power alternatives rated at 25W. Selection between these 25W options depends on tolerance requirements: the HS25 22R J provides ±5% tolerance matching the primary part, while the HS25 22R F offers tighter ±1% tolerance. The HS25 22R F is ROHS3 compliant; the HS25 22R J is RoHS compliant. These 25W variants are suitable only for applications where thermal dissipation requirements do not exceed 25W.

All substitute parts maintain active product status and are available in stock. Selection should be based on application power requirements and tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can the HS25 22R J or HS25 22R F replace the HS50 22R J in all applications?

A: No. The HS25 variants are rated for 25W maximum power dissipation, while the HS50 22R J is rated for 50W. Substitution is valid only for applications where actual power dissipation does not exceed 25W. Exceeding the power rating of a substitute part will result in component failure.

Q: What is the difference between the HS25 22R J and HS25 22R F?

A: Both are 25W, 22 Ohm wirewound resistors with aluminum housing and flanged mounting. The primary difference is tolerance: HS25 22R J provides ±5% tolerance, while HS25 22R F provides ±1% tolerance. The HS25 22R F offers superior accuracy for precision applications. RoHS compliance status also differs: HS25 22R J is RoHS compliant, HS25 22R F is ROHS3 compliant.

Q: Are the physical dimensions compatible between the 50W and 25W variants?

A: The 50W variants (HS50 22R J) measure 1.933" L x 0.559" W to 1.933" L x 1.102" W depending on manufacturer. The 25W variants (HS25 22R J and HS25 22R F) measure 1.075" L x 1.102" W to 1.075" L x 0.559" W. While all share the same height (0.583" seated maximum) and flanged mounting interface, length and width differ. Verify PCB layout compatibility before substitution.

Q: Is the HS50 22R J (ARCOL) equivalent to the HS50 22R J (Ohmite)?

A: Yes. Both parts are electrically and mechanically identical, with matching 22 Ohm resistance, ±5% tolerance, 50W power rating, aluminum housing, flanged mounting, and solder lug termination. Both are active products in stock. Selection between manufacturers can be based on inventory availability or supply chain preference.

Q: What compliance certifications apply to these parts?

A: The HS50 22R J (Ohmite) and HS25 22R F (Ohmite) are ROHS3 compliant. The HS50 22R J (ARCOL) and HS25 22R J (ARCOL) are RoHS compliant. All parts are REACH unaffected or vendor undefined. All are classified under ECCN EAR99.
