Equivalent & Substitute Parts for HS15 15R J Wirewound Chassis Mount Resistor

Part Overview

The HS15 15R J is a 15 Ohm, 15W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is designed for applications requiring precision resistance with high power dissipation capability in a compact flanged aluminum housing with solder lug termination. The part is currently active in production with full RoHS3 compliance. Substitute parts are identified when equivalent resistance values and mounting configurations are required but alternative performance characteristics or availability conditions necessitate component selection from qualified alternatives.

Substitute Part Grouping Explanation

Substitution of the HS15 15R J is permissible when the following core parameters are maintained or improved:

• Resistance value: 15 Ohms (exact match required)
• Composition: Wirewound (required for thermal stability)
• Mounting configuration: Flanged aluminum housing with solder lug termination
• Lead style: Solder lugs (required for mechanical compatibility)
• Package type: Axial, Box configuration

The substitute part 810F15RE (ARCOL Metal-Mite®89 series) qualifies as an equivalent alternative based on matching resistance, composition, housing type, mounting features, and lead style. Differences in tolerance, power rating, and temperature coefficient represent trade-offs that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the HS15 15R J and 810F15RE are active production components with established RoHS compliance certifications. The HS15 15R J maintains RoHS3 compliance status, while the 810F15RE holds RoHS compliance status. Selection between these parts depends on application-specific power dissipation requirements and tolerance specifications. The HS15 15R J provides 15W power rating with ±5% tolerance and ±100ppm/°C temperature coefficient. The 810F15RE provides 10W power rating with superior ±1% tolerance and ±20ppm/°C temperature coefficient. Physical dimensions differ in width (0.440" versus 0.827"), which may impact board layout considerations. Both components share identical length and seated height dimensions, maintaining mechanical compatibility with flanged mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the 810F15RE directly replace the HS15 15R J in all applications?

A: Direct substitution is permissible when the application power dissipation requirement does not exceed 10W. The 810F15RE has a lower power rating (10W versus 15W). If the circuit requires the full 15W dissipation capability of the original part, the 810F15RE is not suitable.

Q: What are the tolerance differences between these parts?

A: The HS15 15R J specifies ±5% tolerance, while the 810F15RE specifies ±1% tolerance. The 810F15RE provides tighter tolerance control, which may be beneficial for precision applications but is not required for general substitution compatibility.

Q: How do the temperature coefficients compare?

A: The HS15 15R J has a temperature coefficient of ±100ppm/°C, while the 810F15RE has ±20ppm/°C. The 810F15RE exhibits superior temperature stability. For applications operating across wide temperature ranges, the lower temperature coefficient of the 810F15RE may provide improved performance consistency.

Q: Are there physical dimension differences that affect mounting?

A: Both parts share identical length (0.783") and seated height (0.433"). The width differs: HS15 15R J is 0.440" wide, while 810F15RE is 0.827" wide. This width difference must be evaluated against available board space and layout constraints.

Q: Do both parts use the same lead style and package configuration?

A: Yes. Both components feature solder lug termination and axial box package configuration with flanged aluminum housing, ensuring mechanical and electrical compatibility with existing mounting infrastructure.

Q: What is the compliance status of each part?

A: The HS15 15R J is RoHS3 compliant. The 810F15RE is RoHS compliant. Both parts meet environmental compliance requirements for their respective standards.
