WNB100FE Equivalent & Substitute Parts

Part Overview

The WNB100FE is a 100 Ohms ±1% 1W through-hole resistor manufactured by Ohmite, part of the WN series wirewound resistor line. This component is an active product with ROHS3 compliance and is designed for applications requiring precision resistance with non-inductive characteristics in axial package configuration. Substitute parts are identified when electrical specifications, mechanical dimensions, and compliance certifications remain identical across packaging variants.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WNB100FE is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Non-inductive characteristic
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C to 150°C
• Package configuration: Axial
• Physical dimensions: 0.130" Dia x 0.276" L (3.30mm x 7.00mm)
• Compliance: ROHS3 Compliant

The WNB100FET is classified as a direct substitute because it maintains identical electrical and mechanical specifications. The only difference is the packaging format (Cut Tape versus standard packaging), which does not affect component performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both WNB100FE and WNB100FET are active products from Ohmite's WN series with identical electrical performance and mechanical compatibility. Selection between these parts should be based on procurement and assembly requirements:

• WNB100FE is suitable for standard component handling and inventory management
• WNB100FET in Cut Tape packaging is optimized for automated pick-and-place assembly processes

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications. No performance degradation occurs when substituting between these variants in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can WNB100FET replace WNB100FE in my circuit design?

A: Yes. Both parts are electrically and mechanically identical. The WNB100FET differs only in packaging format (Cut Tape), which does not affect circuit performance or component functionality.

Q: What is the difference between WNB100FE and WNB100FET?

A: The primary difference is packaging. WNB100FE uses standard packaging, while WNB100FET is supplied in Cut Tape format. Electrical specifications, physical dimensions, and performance characteristics are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both WNB100FE and WNB100FET are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic component applications.

Q: Do these resistors have inductive characteristics?

A: No. Both parts feature non-inductive wirewound construction, making them suitable for applications requiring minimal inductance.

Q: What is the operating temperature range for these parts?

A: Both WNB100FE and WNB100FET operate across -55°C to 150°C with a temperature coefficient of ±20ppm/°C.

Q: Can I use WNB100FET in manual assembly applications?

A: Yes. While WNB100FET is optimized for automated assembly in Cut Tape format, it can be used in manual assembly processes. WNB100FE may be more convenient for manual handling depending on your assembly workflow.
