WNB150FET Equivalent & Substitute Parts

Part Overview

The WNB150FET is a 150 Ohm, 1% tolerance, 1W axial wirewound resistor manufactured by Ohmite. This through-hole component features non-inductive construction and operates across a temperature range of -55°C to 150°C. The part is currently active in production status with ROHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same resistance value, tolerance, power rating, and package configuration.

Substitute Part Grouping Explanation

Substitution eligibility for the WNB150FET is determined by strict equivalence across the following parameters:

• Resistance value: 150 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Features: Non-Inductive
• Package: Axial through-hole
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C to 150°C
• Physical dimensions: 0.130" Dia x 0.276" L (3.30mm x 7.00mm)

The WHB150FET meets all electrical and mechanical parameters required for direct substitution. Both parts are manufactured by Ohmite and maintain identical specifications across resistance, tolerance, power dissipation, construction method, and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both WNB150FET and WHB150FET are active production components from Ohmite with full RoHS compliance. The WHB150FET carries RoHS Compliant status while the WNB150FET specifies ROHS3 Compliant status. Both parts satisfy identical electrical and mechanical requirements for 150 Ohm, 1% tolerance, 1W axial wirewound resistor applications. Selection between these parts may be based on inventory availability, packaging format (both supplied in Tape & Reel), or specific compliance documentation requirements for your application.

Frequently Asked Questions (FAQ)

Q: Can WHB150FET replace WNB150FET in existing designs?
