HS50 1K5 F Equivalent & Substitute Parts

Part Overview

The HS50 1K5 F is a 1.5 kOhms ±1% 50W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is designed for high-power applications requiring precision resistance with stable thermal characteristics. The part is currently active in production with 786 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

The 825F1K5E (ARCOL Metal-Mite®89 series) qualifies as a parametric equivalent based on the following matching criteria:

• Identical resistance value: 1.5 kOhms
• Identical tolerance: ±1%
• Identical composition: Wirewound
• Identical housing material: Aluminum
• Identical mounting feature: Flanges
• Identical lead style: Solder Lugs
• Identical package type: Axial, Box
• RoHS compliant status maintained

The primary difference is power rating (25W versus 50W), which represents a derating consideration rather than an incompatibility. The substitute part operates within the same electrical and mechanical framework as the main part.

Parameter Comparison

Engineering Selection Recommendations

Both the HS50 1K5 F and 825F1K5E maintain active product status and comply with RoHS regulations. The HS50 1K5 F provides 50W power dissipation capacity, while the 825F1K5E is rated for 25W. Selection between these parts depends on the actual power dissipation requirements of the application. If circuit design requires 50W dissipation capability, the HS50 1K5 F is the appropriate choice. If application power requirements do not exceed 25W, the 825F1K5E provides equivalent electrical performance with identical mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 825F1K5E replace the HS50 1K5 F in all applications?

A: The 825F1K5E matches all electrical and mechanical parameters except power rating. Substitution is valid only when circuit power dissipation does not exceed 25W. Applications requiring 50W dissipation must use the HS50 1K5 F.

Q: Are the physical dimensions compatible between these parts?

A: Both parts feature identical mounting characteristics (flanges, solder lugs, axial/box package). The HS50 1K5 F measures 1.933" L x 0.559" W (49.10mm x 14.20mm), while the 825F1K5E measures 1.075" L x 1.102" W (27.30mm x 28.00mm). Verify PCB layout accommodates the substitute part dimensions before implementation.

Q: What is the difference in temperature coefficient between these parts?

A: The HS50 1K5 F has a temperature coefficient of ±25ppm/°C, while the 825F1K5E has ±20ppm/°C. Both values are within precision wirewound resistor specifications. The 825F1K5E exhibits slightly better temperature stability.

Q: Are both parts RoHS compliant?

A: Yes. The HS50 1K5 F is RoHS3 compliant, and the 825F1K5E is RoHS compliant. Both meet environmental regulatory requirements.

Q: What is the primary consideration when selecting between these parts?

A: Power dissipation capacity is the determining factor. Confirm that circuit thermal requirements do not exceed the substitute part's 25W rating before selection.
