Equivalent & Substitute Parts for WHB330FET

Part Overview

The WHB330FET is a 330 Ohm ±1% 1W axial wirewound through-hole resistor manufactured by Ohmite. This component is classified as Active product status and is ROHS3 Compliant. Equivalent and substitute parts are identified when component availability is limited, procurement lead times are extended, or design flexibility permits alternative packaging formats while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the WHB330FET is determined by matching the following critical parameters: resistance value (330 Ohms), tolerance (±1%), power rating (1W), composition (wirewound), package type (axial), and temperature coefficient (±20ppm/°C). Packaging format (Cut Tape, Tape & Reel, or Bulk) does not affect electrical or mechanical compatibility and permits substitution across these formats. Physical dimensions may vary within the axial package category; however, all identified substitutes maintain compatible lead spacing and mounting characteristics for through-hole applications.

Engineering Selection Recommendations

All three parts—WHB330FET, WNB330FET, and 41F330E—are manufactured by Ohmite and maintain Active product status. Selection between these parts is based on packaging format availability and compliance requirements.

WHB330FET is supplied in Cut Tape format and carries ROHS3 Compliant and REACH Unaffected certifications.

WNB330FET is supplied in Tape & Reel format with the additional feature designation of Non-Inductive wirewound construction. This part carries RoHS Compliant certification; REACH status is listed as Vendor Undefined. Inventory availability for WNB330FET is significantly higher (7715 Pcs) compared to WHB330FET (810 Pcs).

41F330E is supplied in Bulk packaging and is part of the Ohmicone® 40 series. This part carries ROHS3 Compliant and REACH Unaffected certifications. Physical dimensions differ from the other two parts (0.126" Dia x 0.437" L versus 0.130" Dia x 0.276" L); operating temperature range is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can WNB330FET replace WHB330FET in my circuit? A: Yes. Both parts share identical electrical specifications: 330 Ohms ±1% tolerance, 1W power rating, wirewound composition, ±20ppm/°C temperature coefficient, and -55°C ~ 150°C operating range. The primary difference is packaging format (Tape & Reel versus Cut Tape) and the Non-Inductive feature designation of WNB330FET. Electrical performance is equivalent.

Q: What is the difference between the WNB330FET and WHB330FET? A: The WNB330FET is designated as Non-Inductive wirewound, whereas the WHB330FET does not carry this feature designation. Both maintain the same resistance, tolerance, power rating, and temperature characteristics. WNB330FET is supplied in Tape & Reel format; WHB330FET is supplied in Cut Tape format.

Q: Can 41F330E be used as a direct substitute? A: 41F330E matches all critical electrical parameters (330 Ohms ±1%, 1W, ±20ppm/°C). However, physical dimensions differ: 41F330E measures 0.126" Dia x 0.437" L compared to 0.130" Dia x 0.276" L for WHB330FET and WNB330FET. Verify that board layout and mechanical clearances accommodate the larger axial length before substitution. Operating temperature range for 41F330E is not specified.

Q: Are there compliance differences between these parts? A: WHB330FET and 41F330E are both ROHS3 Compliant and REACH Unaffected. WNB330FET is RoHS Compliant with Vendor Undefined REACH status. For applications requiring REACH Unaffected certification, WHB330FET or 41F330E are preferred.

Q: Which part should I select for high-volume production? A: WNB330FET offers the highest inventory availability (7715 Pcs) and is supplied in Tape & Reel format, which is standard for automated assembly processes. WHB330FET (810 Pcs) and 41F330E (1211 Pcs) have lower inventory levels.
