WNB750FE Equivalent & Substitute Parts

Part Overview

The WNB750FE is a 750 Ohm ±1% 1W through-hole axial wirewound resistor manufactured by Ohmite. This non-inductive composition resistor operates across -55°C to 150°C and is ROHS3 compliant. The part is currently active in production with 927 units in stock. Substitute parts are identified when equivalent electrical parameters and mechanical form factors are maintained across different packaging configurations or series variants.

Substitute Part Grouping Explanation

Substitute parts for the WNB750FE are classified based on electrical and mechanical parameter equivalence:

Direct Manufacturer Substitute (WNB750FET): Identical electrical specifications and mechanical dimensions. Differs only in packaging format (Cut Tape vs. standard packaging). All critical parameters including resistance, tolerance, power rating, temperature coefficient, and operating range are equivalent.

Parametric Equivalent (WHB750FE): Maintains all electrical specifications and mechanical dimensions. Series designation differs (WH vs. WN). Non-inductive feature designation differs in documentation but composition and electrical performance remain equivalent. Packaging format is Bulk.

Substitution is valid when the following parameters match:

• Resistance value: 750 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package type: Axial
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C to 150°C
• Physical dimensions: 0.130" Dia x 0.276" L

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products manufactured by Ohmite with ROHS3 compliance and REACH unaffected status. Selection between WNB750FE, WNB750FET, and WHB750FE is determined by packaging and supply requirements:

WNB750FE: Use when standard packaging is specified or preferred. Suitable for general procurement with 927 units available.

WNB750FET: Use when Cut Tape packaging is required for automated assembly processes. Highest inventory availability at 2346 units supports high-volume applications.

WHB750FE: Use when Bulk packaging is acceptable and WN series variants are unavailable. Maintains full electrical and mechanical equivalence with 857 units in stock.

All three parts satisfy identical electrical circuit requirements and mechanical PCB mounting specifications.

Frequently Asked Questions (FAQ)

Q: Can WNB750FET replace WNB750FE in a circuit? A: Yes. WNB750FET is electrically and mechanically identical to WNB750FE. The only difference is packaging format (Cut Tape vs. standard). Both deliver identical performance in the circuit.

Q: What is the difference between WNB750FE and WHB750FE? A: Both parts are electrically equivalent with identical resistance, tolerance, power rating, and temperature specifications. The series designation differs (WN vs. WH), and packaging format differs (standard vs. Bulk). Mechanical dimensions and performance are equivalent.

Q: Are all three parts suitable for -55°C to 150°C applications? A: Yes. All three parts operate across the full -55°C to 150°C temperature range with ±20ppm/°C temperature coefficient.

Q: Which part should I select for high-volume automated assembly? A: WNB750FET in Cut Tape packaging is optimized for automated pick-and-place assembly and offers the highest inventory level at 2346 units.

Q: Are all parts ROHS3 compliant? A: Yes. WNB750FE, WNB750FET, and WHB750FE are all ROHS3 compliant.

Q: Can I use these parts interchangeably on the same PCB? A: Yes. All three parts have identical axial package dimensions (0.130" Dia x 0.276" L) and two terminations, allowing direct substitution in PCB designs.
