Substitute Part Grouping Explanation

Substitution for the HS10 2R J is determined by strict equivalence across the following critical parameters:

• Resistance value: 2 Ohms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Temperature coefficient: ±100ppm/°C
• Housing material: Aluminum
• Mounting configuration: Flanges with solder lugs
• Package classification: Axial, Box

The identified substitute part maintains identical electrical specifications and mechanical mounting characteristics, ensuring direct functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite HS10 2R J and ARCOL HS10 2R J are active production components with identical electrical and mechanical specifications. Selection between these parts may be based on:

• Regulatory compliance requirements: The Ohmite variant carries ROHS3 Compliant and REACH Unaffected certifications, while the ARCOL variant is RoHS Compliant with Vendor Undefined REACH status.
• Inventory availability: Ohmite variant has 734 units in stock; ARCOL variant has 802 units in stock.
• Supply chain sourcing preferences and lead time considerations.

Both parts are suitable for direct substitution in applications requiring 2 Ohms ±5% 10W wirewound resistors with aluminum chassis mount construction.

Frequently Asked Questions (FAQ)

Q: Can the ARCOL HS10 2R J replace the Ohmite HS10 2R J in existing designs?

A: Yes. Both parts share identical resistance, tolerance, power rating, composition, temperature coefficient, housing material, and mounting configuration. Direct substitution is electrically and mechanically compatible.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: resistance value (2 Ohms), tolerance (±5%), power rating (10W), composition (wirewound), temperature coefficient (±100ppm/°C), housing type (aluminum), mounting feature (flanges), and lead style (solder lugs).

Q: Are there dimensional differences between the two variants?

A: The Ohmite variant has dimensions of 0.626" L x 0.335" W (15.90mm x 8.50mm). The ARCOL variant has dimensions of 0.626" L x 0.650" W (15.90mm x 16.50mm). Height-seated maximum is 0.346" (8.80mm) for both. Verify PCB layout compatibility before substitution.

Q: What compliance certifications apply to these parts?

A: The Ohmite HS10 2R J is ROHS3 Compliant and REACH Unaffected. The ARCOL HS10 2R J is RoHS Compliant with Vendor Undefined REACH status. Both carry EAR99 ECCN classification.

Q: Which variant should be selected for new designs?

A: Selection depends on specific regulatory requirements and supply chain strategy. Confirm compliance certifications align with end-application requirements before design implementation.
