WHB330FE Equivalent & Substitute Parts

Part Overview

The WHB330FE is a 330 Ohms ±1% 1W through-hole resistor manufactured by Ohmite in axial wirewound composition. This component is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and regulatory certifications align with the original component requirements for direct circuit board replacement.

Key Parameters

Substitute Part Grouping Explanation

The 41F330E qualifies as a manufacturer-recommended substitute for the WHB330FE based on the following critical parameters:

• Identical resistance value: 330 Ohms
• Matching tolerance specification: ±1%
• Equivalent power rating: 1W
• Same composition type: Wirewound
• Identical package configuration: Axial with 2 terminations
• Matching temperature coefficient: ±20ppm/°C
• Equivalent regulatory compliance: ROHS3 Compliant, REACH Unaffected

Physical dimensions differ between the two parts (WHB330FE: 0.130" Dia x 0.276" L versus 41F330E: 0.126" Dia x 0.437" L), requiring verification of board layout constraints during substitution.

Parameter Comparison

Engineering Selection Recommendations

The 41F330E is the manufacturer-recommended substitute for WHB330FE applications. Both components maintain Active product status with identical electrical specifications and full regulatory compliance under RoHS3 and REACH standards. Selection between these parts depends on physical space constraints on the printed circuit board, as the 41F330E exhibits greater axial length (0.437" versus 0.276"). Both components are suitable for applications requiring 330 Ohm ±1% 1W wirewound resistors with -55°C to 150°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 41F330E directly replace the WHB330FE in all applications?

A: Electrical substitution is valid based on matching resistance, tolerance, power rating, and temperature coefficient. Physical board layout must accommodate the 41F330E's longer axial length (0.437" versus 0.276").

Q: What are the critical parameters for substitution eligibility?

A: Resistance value (330 Ohms), tolerance (±1%), power rating (1W), composition (Wirewound), and package type (Axial) must match exactly. Temperature coefficient and operating range specifications must be equivalent or superior.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both WHB330FE and 41F330E are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the primary difference between these two parts?

A: The primary difference is physical dimension. The 41F330E (Ohmicone® 40 series) is longer (0.437" L) compared to the WHB330FE (WH series) at 0.276" L, while maintaining identical electrical characteristics.

Q: Are there inventory considerations for selection?

A: Both parts are listed as Active with current stock availability. Inventory levels may vary; consult supplier data for current availability of either part number.
