HS50 1K5 F Equivalent & Substitute Parts

Part Overview

The HS50 1K5 F is a 50W wirewound chassis mount resistor manufactured by Ohmite, rated at 1.5 kOhms with ±1% tolerance. This component is designed for high-power applications requiring stable resistance performance in aluminum-housed configurations with flanged mounting. The part maintains Active product status with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when inventory constraints, lead time requirements, or application-specific packaging needs necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the HS50 1K5 F is determined by the following critical parameters:

• Resistance Value: Must be 1.5 kOhms
• Tolerance: Must be ±1%
• Composition: Must be Wirewound
• Housing Type: Must be Aluminum
• Mounting Feature: Must include Flanges
• Lead Style: Must be Solder Lugs
• RoHS Compliance: Must be RoHS Compliant

The ARCOL 825F1K5E meets all electrical and mechanical compatibility criteria. However, the power rating differs at 25W versus the original 50W specification, which represents a functional limitation in maximum dissipation capacity.

Parameter Comparison

Engineering Selection Recommendations

Both the HS50 1K5 F and 825F1K5E maintain Active product status with full RoHS compliance, ensuring regulatory alignment for current applications. The primary distinction lies in power dissipation capacity: the HS50 1K5 F provides 50W rating, while the ARCOL substitute is rated at 25W. Selection between these components must be based on the actual power dissipation requirements of the application circuit. The ARCOL 825F1K5E occupies a smaller physical footprint (27.30mm versus 49.10mm length) while maintaining identical height and width dimensions, which may present layout advantages in space-constrained designs where power dissipation does not exceed 25W.

Frequently Asked Questions (FAQ)

Q: Can the ARCOL 825F1K5E be used as a direct replacement for the HS50 1K5 F?

A: Electrical and mechanical compatibility is confirmed for resistance value, tolerance, composition, housing, mounting, and lead style. However, the 25W power rating of the ARCOL part is half that of the original 50W component. Substitution is valid only when circuit power dissipation remains below 25W.

Q: What are the dimensional differences between these parts?

A: The ARCOL 825F1K5E is shorter in length (27.30mm versus 49.10mm) but maintains identical width (28.00mm) and height (14.80mm). Both parts use flanged solder lug mounting, ensuring compatible board-level installation.

Q: Are there differences in temperature stability?

A: The HS50 1K5 F specifies 25ppm/°C temperature coefficient, while the ARCOL 825F1K5E is rated at ±20ppm/°C. Both values fall within acceptable ranges for wirewound resistor applications, though the original part offers tighter temperature stability.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the HS50 1K5 F and 825F1K5E are RoHS Compliant with MSL rating of 1 (Unlimited), meeting current regulatory standards for electronic component sourcing.
