HS250 1K5 F Equivalent & Substitute Parts

Part Overview

The HS250 1K5 F is a 250W 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 is currently active in production with 874 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

Substitution eligibility for the HS250 1K5 F is determined by the following critical parameters:

• Resistance value: 1.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Wirewound (exact match required)
• Housing type: Aluminum (exact match required)
• Mounting feature: Flanges (exact match required)
• Lead style: M6 Threaded (exact match required)
• Power rating: Equal to or greater than 250W

The HS200 1K5 F meets all electrical specifications but operates at 200W maximum power. This part is classified as a parametric equivalent with reduced power capacity and represents a downgrade in thermal handling capability.

Parameter Comparison

Engineering Selection Recommendations

The HS250 1K5 F is the primary specification for applications requiring 250W dissipation capacity. The HS200 1K5 F substitute is suitable only for applications where the actual power dissipation does not exceed 200W. Both parts maintain RoHS compliance and identical electrical resistance and tolerance specifications. The HS200 1K5 F features a smaller footprint (89.70mm x 45.50mm versus 109.70mm x 72.50mm) while maintaining the same seated height. Selection between these parts depends on circuit power requirements and available mounting space.

Frequently Asked Questions (FAQ)

Q: Can the HS200 1K5 F replace the HS250 1K5 F in all applications?

A: No. The HS200 1K5 F is rated for 200W maximum power dissipation, compared to 250W for the HS250 1K5 F. Substitution is valid only when actual circuit power dissipation remains below 200W.

Q: Are the physical dimensions compatible between these parts?

A: Both parts share identical seated height (1.646" / 41.80mm) and M6 threaded lead style. The HS200 1K5 F has a smaller footprint in length and width. Verify mounting bracket and thermal management design accommodate the smaller dimensions.

Q: Do both parts meet current compliance standards?

A: Yes. The HS250 1K5 F is RoHS Compliant. The HS200 1K5 F is ROHS3 Compliant. Both meet current environmental and regulatory requirements.

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

A: The HS250 1K5 F specifies 25ppm/°C. The HS200 1K5 F specifies ±25ppm/°C. Both values indicate similar temperature stability performance for this resistor category.

Q: Are packaging differences significant for procurement?

A: The HS250 1K5 F is supplied in Box packaging. The HS200 1K5 F is supplied in Bulk packaging. Verify your procurement and handling procedures accommodate the packaging format.
