WHC470FE Equivalent & Substitute Parts

Part Overview

The WHC470FE is a 470 Ohms ±1% 2W through-hole resistor with axial wirewound construction manufactured by Ohmite. This component is classified as Active product status and is ROHS3 compliant. Equivalent and substitute parts are identified when design requirements permit variations in packaging format or specific wirewound construction characteristics while maintaining identical electrical performance and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WHC470FE is determined by matching the following critical parameters: resistance value (470 Ohms), tolerance (±1%), power rating (2W), composition (wirewound), temperature coefficient (±20ppm/°C), operating temperature range (-55°C ~ 150°C), package type (axial), and physical dimensions (0.180" Dia x 0.449" L). Variations in packaging format (Tape & Reel versus Bulk) and wirewound construction characteristics (standard versus non-inductive) do not affect electrical or mechanical compatibility when these core parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

All three parts—WHC470FE, WHC470FET, and WNC470FE—maintain Active product status and ROHS3 compliance. Selection between these parts is determined by packaging requirements and application-specific construction characteristics. The WHC470FE and WHC470FET are functionally identical standard wirewound resistors; the primary distinction is packaging format (Bulk versus Tape & Reel). The WNC470FE provides non-inductive wirewound construction while maintaining all other electrical and mechanical specifications. Component selection should be based on procurement format availability, assembly process requirements, and any application-specific need for non-inductive characteristics.

Frequently Asked Questions (FAQ)

Q: Can WHC470FET replace WHC470FE in a circuit design? A: Yes. WHC470FET is electrically and mechanically identical to WHC470FE. The only difference is packaging format (Tape & Reel versus Bulk). Both parts meet the same electrical specifications and physical dimensions.

Q: What is the difference between WHC470FE and WNC470FE? A: Both parts share identical electrical parameters (470 Ohms, ±1%, 2W, ±20ppm/°C, -55°C ~ 150°C) and physical dimensions. The WNC470FE features non-inductive wirewound construction, whereas WHC470FE uses standard wirewound construction. Selection depends on whether non-inductive characteristics are required for the application.

Q: Are all three parts ROHS3 compliant? A: Yes. WHC470FE, WHC470FET, and WNC470FE are all ROHS3 compliant and REACH unaffected.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR) and Bulk packaging formats do not affect electrical performance. The choice between WHC470FET (Tape & Reel) and WHC470FE (Bulk) is determined by assembly process requirements and procurement logistics.

Q: Can WNC470FE be used in applications where standard wirewound construction is specified? A: WNC470FE is a parametric equivalent with non-inductive construction. Use in applications originally specified for standard wirewound construction requires confirmation that non-inductive characteristics do not conflict with circuit requirements.
