HS100 68R J Equivalent & Substitute Parts

Part Overview

The HS100 68R J is a 68 Ohms ±5% 100W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is designed for high-power applications requiring reliable thermal dissipation through aluminum housing with flanged mounting. The part is currently active in production with 956 units in stock. Equivalent and substitute parts are identified when component availability is constrained, supply chain disruptions occur, or design flexibility permits cross-manufacturer sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the HS100 68R J is determined by strict equivalence across the following critical parameters:

• Resistance value: 68 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 100W (exact match required)
• Composition: Wirewound (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Housing material: Aluminum (exact match required)
• Mounting configuration: Flanged solder lugs (exact match required)
• Package classification: Axial, Box (exact match required)

The identified substitute part HS100 68R J from ARCOL meets all electrical and mechanical parameters. Both the original Ohmite part and the ARCOL equivalent share identical resistance, tolerance, power rating, composition, temperature coefficient, and mounting characteristics. Dimensional variations in width (1.075" vs. 1.870") do not affect functional substitution when mounting space permits the larger footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite HS100 68R J and ARCOL HS100 68R J are active production components with full RoHS compliance. Selection between these parts should be based on:

• Mounting space availability: The ARCOL variant has increased width (1.870" vs. 1.075"), requiring verification that PCB or chassis layout accommodates the larger footprint.
• Supply chain status: The ARCOL part has 1018 units in stock compared to 956 units for the Ohmite part, providing additional availability margin.
• Regulatory compliance: Both parts meet RoHS requirements. The Ohmite part carries ROHS3 certification; the ARCOL part carries standard RoHS certification.
• Thermal performance: Identical temperature coefficient and power rating ensure equivalent thermal behavior in circuit operation.

Frequently Asked Questions (FAQ)

Q: Can the ARCOL HS100 68R J directly replace the Ohmite HS100 68R J?

A: Yes, provided mounting space permits the increased width dimension (1.870" vs. 1.075"). All electrical parameters, power rating, tolerance, and thermal characteristics are identical.

Q: What is the significance of the width difference between these parts?

A: The ARCOL variant is 0.795" wider. This dimensional difference does not affect electrical performance but requires physical space verification in the application. Height and length dimensions are equivalent.

Q: Are both parts RoHS compliant?

A: Yes. The Ohmite part is ROHS3 compliant; the ARCOL part is RoHS compliant. Both meet environmental regulatory requirements for lead-free manufacturing.

Q: What determines substitution eligibility for this resistor category?

A: Substitution requires exact equivalence in resistance value, tolerance, power rating, composition (wirewound), temperature coefficient, housing material (aluminum), mounting configuration (flanged solder lugs), and package type (axial, box). Dimensional variants are acceptable if physical space permits.

Q: Are there inventory advantages to selecting one part over the other?

A: The ARCOL HS100 68R J has 1018 units in stock versus 956 units for the Ohmite part, providing a 62-unit inventory advantage.
