NHS100 200R F Equivalent & Substitute Parts

Part Overview

The NHS100 200R F is a 100-watt wirewound chassis mount resistor manufactured by Ohmite, part of the ARCOL HS series. This component is rated for 200 ohms with ±1% tolerance and features non-inductive, pulse-withstanding construction in an aluminum housing. The part maintains Active product status with full ROHS3 compliance and REACH unaffected classification. Substitute parts are identified based on matching electrical specifications, mechanical dimensions, mounting characteristics, and regulatory compliance requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the NHS100 200R F is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (200 Ohms), tolerance (±1%), power rating (100W), and temperature coefficient (±100ppm/°C) must match exactly. Wirewound composition is required to maintain non-inductive and pulse-withstanding characteristics.

Mechanical Parameters: Aluminum housing type, flange mounting feature, and solder lug lead style must be identical. Physical dimensions (2.567" L x 1.870" W x 0.949" H) establish the form factor for chassis integration.

Regulatory Parameters: ROHS3 compliance and REACH unaffected status are mandatory for equivalent substitution in regulated applications.

Only parts meeting all specified parameters across electrical, mechanical, and regulatory categories qualify as direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

The NHS100 200R F maintains Active product status with full regulatory compliance under ROHS3 and REACH unaffected classifications. Component selection should prioritize parts with identical Active status and matching compliance certifications to ensure long-term supply chain viability and regulatory adherence in end-use applications.

Chassis mount wirewound resistors with aluminum housing and flange mounting are specified for applications requiring thermal dissipation, mechanical stability, and pulse withstanding capability. Exact dimensional matching ensures proper fit within existing mechanical assemblies and thermal management designs.

Frequently Asked Questions (FAQ)

Q: What makes a part a direct equivalent to the NHS100 200R F?

A: A direct equivalent must match all electrical specifications (200 Ohms, ±1% tolerance, 100W power rating, ±100ppm/°C temperature coefficient), mechanical characteristics (aluminum housing, flange mounting, solder lugs, exact dimensions), and regulatory status (ROHS3 compliant, REACH unaffected). Wirewound composition is required to maintain non-inductive and pulse-withstanding performance.

Q: Can I substitute a different resistance value or tolerance?

A: No. The 200-ohm value and ±1% tolerance are circuit-critical specifications. Substitution with different values or tolerances will alter circuit performance and is not permitted for direct equivalence.

Q: Are there compatibility concerns with the flange mounting feature?

A: The flange mounting feature is integral to the mechanical design. Substitute parts must retain identical flange configuration and dimensions (2.567" L x 1.870" W x 0.949" H) to ensure proper chassis integration and thermal contact.

Q: What is the significance of the wirewound composition?

A: Wirewound construction provides the non-inductive and pulse-withstanding characteristics specified for this component. Alternative resistor types (film, thick-film) do not provide equivalent performance and are not suitable substitutes.

Q: Does RoHS3 compliance affect substitution eligibility?

A: Yes. ROHS3 compliance is a mandatory regulatory requirement. Substitute parts must maintain identical ROHS3 compliance status to ensure regulatory adherence in the end application.
