WHC100FE Equivalent & Substitute Parts

Part Overview

The WHC100FE is a 100 Ohms ±1% 2W axial wirewound through-hole resistor manufactured by Ohmite. This component is classified as Active product status with full RoHS3 compliance. The WHC100FE is supplied in standard packaging configuration and is suitable for applications requiring precision resistive elements with stable temperature characteristics across industrial temperature ranges.

Substitute parts are identified when electrical specifications, mechanical dimensions, and compliance certifications remain equivalent, enabling direct functional replacement in circuit designs without performance degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WHC100FE is determined by the following critical parameters:

• Resistance value: 100 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)
• Operating temperature range: -55°C to 150°C (exact match required)
• Physical dimensions: 0.180" Dia x 0.449" L (exact match required)
• Termination count: 2 (exact match required)

The WHC100FE has one identified substitute: WHC100FET. This substitute maintains all critical electrical and mechanical parameters while differing only in packaging format (Tape & Reel versus standard packaging) and the addition of non-inductive construction features.

Parameter Comparison

Engineering Selection Recommendations

Both WHC100FE and WHC100FET are Active status components from Ohmite with full RoHS compliance certifications. The WHC100FET provides an enhanced specification through non-inductive construction, which reduces parasitic inductance effects in high-frequency applications. The primary distinction between these parts is packaging format: WHC100FE is supplied in standard packaging, while WHC100FET is supplied in Tape & Reel format for automated assembly processes.

Selection between these parts should be based on assembly methodology and application requirements. Standard packaging is appropriate for manual assembly or low-volume production. Tape & Reel packaging is suitable for high-volume automated assembly operations. Both parts satisfy identical electrical performance requirements and environmental compliance standards.

Frequently Asked Questions (FAQ)

Q: Can WHC100FET replace WHC100FE in existing designs?

A: Yes. The WHC100FET maintains all critical electrical parameters (resistance, tolerance, power rating, temperature coefficient, and operating temperature range) and physical dimensions required for direct functional replacement. The non-inductive feature of WHC100FET provides enhanced performance in high-frequency applications without compromising compatibility.

Q: What is the difference between standard packaging and Tape & Reel packaging?

A: Standard packaging is used for manual component handling and low-volume assembly. Tape & Reel packaging is configured for automated pick-and-place assembly equipment in high-volume manufacturing. Both packaging formats contain identical components with identical electrical specifications.

Q: Are there compliance differences between WHC100FE and WHC100FET?

A: Both parts are RoHS compliant. WHC100FE carries RoHS3 certification, while WHC100FET carries RoHS certification. Both meet environmental compliance requirements for electronic component use.

Q: What does non-inductive construction mean for WHC100FET?

A: Non-inductive construction reduces parasitic inductance in the resistor element. This feature is beneficial in high-frequency circuits where inductive effects could cause impedance variations or signal distortion. For DC or low-frequency applications, this feature provides no functional advantage but does not introduce any performance penalty.

Q: Can I use WHC100FE in applications requiring non-inductive characteristics?

A: The WHC100FE is standard wirewound construction without non-inductive specification. For applications with specific non-inductive requirements, WHC100FET is the appropriate selection.
