WHB470FE Equivalent & Substitute Parts

Part Overview

The WHB470FE is a 470 Ohms ±1% 1W through-hole resistor with axial wirewound composition manufactured by Ohmite. This component is classified as Active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter range for axial wirewound resistors in this resistance and power rating category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WHB470FE is determined by strict equivalence across the following critical parameters:

• Resistance value: 470 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package configuration: Axial with 2 terminations
• Temperature coefficient: ±20ppm/°C
• RoHS3 compliance status
• Operating temperature range capability

The substitute part 41F470E meets all these criteria and is therefore electrically and mechanically interchangeable with the WHB470FE.

Parameter Comparison

Engineering Selection Recommendations

Both WHB470FE and 41F470E are Active status components with identical electrical specifications and full RoHS3 compliance. Selection between these parts is based on physical space constraints and packaging requirements. The WHB470FE features a more compact axial profile (3.30mm diameter, 7.00mm length), while the 41F470E provides a longer axial configuration (3.20mm diameter, 11.10mm length). Both components maintain equivalent electrical performance across the specified operating temperature range of -55°C to 150°C with ±20ppm/°C temperature coefficient stability.

Frequently Asked Questions (FAQ)

Q: Can 41F470E be used as a direct replacement for WHB470FE?

A: Yes. Both parts are 470 Ohms ±1% 1W axial wirewound resistors with identical electrical specifications, temperature coefficients, and RoHS3 compliance. The primary difference is physical dimension, which must be evaluated against available board space.

Q: What are the physical dimension differences between these parts?

A: WHB470FE measures 0.130" diameter by 0.276" length (3.30mm x 7.00mm). The 41F470E measures 0.126" diameter by 0.437" length (3.20mm x 11.10mm). The 41F470E is longer but slightly narrower in diameter.

Q: Are both parts RoHS compliant?

A: Yes. Both WHB470FE and 41F470E are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What determines substitution eligibility for this resistor category?

A: Substitution is determined by matching resistance value, tolerance, power rating, composition type, package configuration, temperature coefficient, and compliance certifications. Dimensional variations are acceptable provided the component fits within the available board space.

Q: Do these parts have different operating temperature ranges?

A: The WHB470FE specifies -55°C to 150°C operating range. The 41F470E does not specify an upper temperature limit in the provided data. Both maintain ±20ppm/°C temperature coefficient performance.
