HS25 24R J Equivalent & Substitute Parts

Part Overview

The HS25 24R J is a 24 Ohms ±5% 25W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is designed for applications requiring high power dissipation with stable resistance values and is currently in active production status. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or when design flexibility permits selection from qualified alternatives meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS25 24R J is determined by matching the following critical parameters: resistance value (24 Ohms), tolerance (±5%), power rating (25W), composition (wirewound), temperature coefficient (±100ppm/°C), housing material (aluminum), mounting configuration (flanges), lead style (solder lugs), and package type (axial, box). The ARCOL HS25 24R J qualifies as a parametric equivalent based on identical electrical specifications and compatible mechanical dimensions. Dimensional variations within the width parameter do not affect functional interchangeability when mounting flanges and solder lug configurations remain consistent.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite HS25 24R J and ARCOL HS25 24R J are active production components with confirmed RoHS compliance. The Ohmite variant carries ROHS3 Compliant certification, while the ARCOL variant carries RoHS Compliant status. Both components meet REACH unaffected or vendor undefined classifications and carry EAR99 ECCN designation. Selection between these equivalents may be based on supply availability, as the Ohmite variant currently maintains 816 pieces in stock while the ARCOL variant maintains 694 pieces. The width dimension difference (0.559" versus 1.102") should be evaluated against available mounting space in the target application, though both maintain identical length and height specifications.

Frequently Asked Questions (FAQ)

Q: Can the ARCOL HS25 24R J directly replace the Ohmite HS25 24R J? A: Yes. Both components share identical electrical specifications (24 Ohms ±5%, 25W, wirewound, ±100ppm/°C) and compatible mechanical configurations (aluminum housing, flanges, solder lugs, axial box package). The width dimension difference does not affect electrical performance or standard mounting applications.

Q: What is the significance of the width dimension difference? A: The Ohmite variant measures 0.559" (14.20mm) in width, while the ARCOL variant measures 1.102" (28.00mm). This difference should be verified against available mounting space in the target circuit board or chassis layout. Both variants maintain identical length (1.075") and height (0.583") specifications.

Q: Are both parts RoHS compliant? A: Yes. The Ohmite HS25 24R J is ROHS3 Compliant. The ARCOL HS25 24R J is RoHS Compliant. Both meet regulatory requirements for lead-free and restricted substance compliance.

Q: What is the difference in moisture sensitivity between these parts? A: The Ohmite variant lists Moisture Sensitivity Level as Not Applicable. The ARCOL variant lists MSL 1 (Unlimited). For applications in controlled environments, both are suitable. For high-humidity or thermal cycling applications, verify specific storage and handling requirements with the respective manufacturer datasheets.

Q: Which variant should be selected based on current inventory? A: The Ohmite HS25 24R J currently maintains higher inventory (816 pieces) compared to the ARCOL variant (694 pieces). Selection should prioritize availability requirements and delivery timeline constraints for your application.
