NHS100 2R F Equivalent & Substitute Parts

Part Overview

The NHS100 2R F is a 100-watt wirewound chassis mount resistor manufactured by Ohmite, part of the ARCOL HS series. This component is rated at 2 ohms with ±1% tolerance and features aluminum housing with flanged mounting. The part is currently active in production with 1146 units in stock. Equivalent and substitute parts are identified when inventory constraints, lead time requirements, or supply chain disruptions necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NHS100 2R F is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (2 Ohms), tolerance (±1%), power rating (100W), composition (wirewound), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Parameters: Housing type (aluminum), mounting feature (flanges), lead style (solder lugs), and physical dimensions (2.567" L x 1.870" W x 0.949" H) must match exactly.

Compliance Parameters: RoHS3 compliance status must be maintained.

Series Designation: Parts must belong to the ARCOL HS series family.

The substitute part HS100E6 2R F M193 meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the NHS100 2R F and HS100E6 2R F M193 are active production components manufactured by Ohmite with full ROHS3 compliance. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical performance differences.

The NHS100 2R F carries higher current inventory (1146 units) and represents the primary specification. The HS100E6 2R F M193 is a direct parametric equivalent with 739 units available and serves as a substitute when primary part availability is constrained.

Both parts satisfy identical electrical performance requirements, mechanical mounting specifications, and regulatory compliance standards. Substitution between these parts does not require circuit redesign, PCB layout modification, or thermal management recalculation.

Frequently Asked Questions (FAQ)

Q: Are NHS100 2R F and HS100E6 2R F M193 electrically interchangeable?
