HS50 220R J Equivalent & Substitute Parts

Part Overview

The HS50 220R J is a 220 Ohms ±5% 50W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is actively produced and maintains 981 pieces in current inventory. The HS50 220R J serves applications requiring high power dissipation with aluminum housing and flanged mounting configuration. Substitute parts become necessary when design requirements shift toward lower power ratings, improved tolerance specifications, or alternative inventory availability while maintaining the same resistance value and core electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS50 220R J is determined by the following mandatory parameters: resistance value (220 Ohms), composition (wirewound), housing type (aluminum), mounting feature (flanges), lead style (solder lugs), and package type (axial, box). All identified substitute parts maintain these core specifications.

The substitute parts HS25 220R F and HS25 220R J differ from the main part in two parameters: power rating (25W versus 50W) and tolerance specification (±1% for HS25 220R F, ±5% for HS25 220R J). These differences define the substitution scope and determine application suitability.

Parameter Comparison

Engineering Selection Recommendations

The HS25 220R J provides direct substitution for applications where 25W power dissipation is sufficient. This part maintains identical tolerance (±5%), temperature coefficient (±100ppm/°C), and all mechanical specifications as the HS50 220R J while reducing physical dimensions. Both parts are ROHS3 compliant and actively produced.

The HS25 220R F offers improved tolerance specification (±1% versus ±5%) with the same 25W power rating. This part is RoHS compliant and includes pulse withstanding features. Selection of HS25 220R F is appropriate when tighter tolerance requirements are necessary and 25W power capacity meets application demands.

Substitution from HS50 220R J to either 25W variant is valid only when circuit design confirms that maximum power dissipation does not exceed 25W under all operating conditions. Power rating reduction represents the primary design constraint for substitution eligibility.

Frequently Asked Questions (FAQ)

Q: Can HS25 220R J replace HS50 220R J in all applications?

A: HS25 220R J is a valid substitute only when the application's maximum power dissipation requirement does not exceed 25W. The 50W-rated HS50 220R J is required for circuits dissipating power between 25W and 50W.

Q: What is the tolerance difference between HS25 220R F and HS25 220R J?

A: HS25 220R F maintains ±1% tolerance while HS25 220R J maintains ±5% tolerance. Both parts have identical 220 Ohm resistance and 25W power rating. Selection depends on circuit tolerance requirements.

Q: Are all substitute parts RoHS compliant?

A: HS50 220R J and HS25 220R J are ROHS3 compliant. HS25 220R F is RoHS compliant. Both compliance levels are acceptable for most applications; verify specific project requirements if RoHS3 certification is mandatory.

Q: Do substitute parts have identical physical dimensions?

A: No. HS50 220R J measures 1.933" L x 0.559" W (49.10mm x 14.20mm). HS25 220R F measures 1.075" L x 1.102" W (27.30mm x 28.00mm). HS25 220R J measures 1.075" L x 0.559" W (27.30mm x 14.20mm). All three parts share identical height (0.583" / 14.80mm) and flanged mounting configuration.

Q: Can HS50 220R J be substituted with HS25 220R F?

A: HS25 220R F is a valid substitute only when 25W power dissipation capacity is sufficient for the application. The ±1% tolerance of HS25 220R F exceeds the ±5% specification of HS50 220R J, making it suitable for applications requiring improved accuracy.
