HS10 10R J Wirewound Chassis Mount Resistor - Equivalent & Substitute Parts

Part Overview

The HS10 10R J is a 10 Ohm, 10W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is an active product with full inventory availability (894 pcs in stock). The resistor features aluminum housing with flanged mounting and solder lug termination, designed for applications requiring precision power dissipation in compact form factors. Substitute parts are identified to provide alternatives with equivalent electrical performance and mechanical compatibility for procurement flexibility or inventory management.

Substitute Part Grouping Explanation

Substitute parts for the HS10 10R J are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

• Resistance value: 10 Ohms (exact match required)
• Power rating: 10W (exact match required)
• Composition: Wirewound (exact match required)
• Housing type: Aluminum (exact match required)
• Mounting feature: Flanges (exact match required)
• Lead style: Solder Lugs (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)

The identified substitute part HS10 10R F meets all core electrical parameters and mechanical specifications. Tolerance variation (±1% vs ±5%) represents an improvement in precision and does not preclude substitution. Dimensional differences in width (16.50mm vs 8.50mm) are within the same package category and do not affect functional compatibility for chassis mount applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HS10 10R J and HS10 10R F are active products with full RoHS compliance and equivalent electrical performance. The HS10 10R F offers improved tolerance specification (±1% vs ±5%), which provides tighter resistance accuracy without compromising functional compatibility. Both components maintain identical power dissipation capability, temperature coefficient, and mechanical mounting characteristics.

Selection between these parts should be based on procurement availability, tolerance requirements for the specific application, and inventory status. The HS10 10R F includes pulse withstanding capability as an additional feature. Both parts are suitable for direct substitution in chassis mount resistor applications requiring 10W power dissipation at 10 Ohms.

Frequently Asked Questions (FAQ)

Q: Can HS10 10R F replace HS10 10R J in existing designs?

A: Yes. Both parts share identical resistance value, power rating, temperature coefficient, housing type, mounting features, and lead style. The improved tolerance of HS10 10R F (±1%) is a functional enhancement that does not affect compatibility.

Q: What is the significance of the tolerance difference between ±5% and ±1%?

A: Tolerance defines the acceptable resistance variation from the nominal 10 Ohm value. HS10 10R J allows variation between 9.5 and 10.5 Ohms. HS10 10R F allows variation between 9.9 and 10.1 Ohms. Applications requiring tighter resistance accuracy benefit from the ±1% specification.

Q: Are there dimensional differences that affect mounting?

A: Both parts maintain identical length (15.90mm) and seated height (8.80mm). Width differs (8.50mm vs 16.50mm), but both conform to the same Axial, Box package category and flange mounting specification. Mounting compatibility is preserved.

Q: What compliance certifications apply to both parts?

A: Both HS10 10R J and HS10 10R F are RoHS compliant. HS10 10R J carries ROHS3 certification. HS10 10R F carries standard RoHS certification. Both meet REACH and EAR99 export classification requirements.

Q: Is inventory status a factor in part selection?

A: Both parts maintain active inventory status with comparable stock levels (894 pcs for HS10 10R J, 889 pcs for HS10 10R F). Procurement decisions may consider current availability and lead times from respective suppliers.
