Key Parameters

Substitute Part Grouping Explanation

The WNC330FET qualifies as a parametric equivalent to the WHC330FET based on the following criteria:

• Identical resistance value: 330 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 2W
• Same composition family: Wirewound
• Identical package configuration: Axial
• Matching temperature coefficient: ±20ppm/°C
• Identical operating temperature range: -55°C ~ 150°C
• Identical physical dimensions: 0.180" Dia x 0.449" L (4.57mm x 11.40mm)
• Equivalent compliance certifications: ROHS3 Compliant, REACH Unaffected

The primary distinction between these components is the non-inductive feature designation in the WNC330FET series, which represents a design variation within the same electrical and mechanical specification envelope.

Parameter Comparison

Engineering Selection Recommendations

Both WHC330FET and WNC330FET maintain Active product status with identical ROHS3 compliance and REACH unaffected certifications. Selection between these components should be based on circuit application requirements. The WNC330FET non-inductive variant is suitable for applications where inductance minimization is a design criterion. The WHC330FET standard wirewound configuration is appropriate for general-purpose applications where inductance characteristics are not a limiting factor. Both components are suitable for direct substitution where electrical specifications and mechanical fit requirements are met.

Frequently Asked Questions (FAQ)

Q: Can WNC330FET replace WHC330FET in any application?

A: WNC330FET qualifies as a direct substitute where the electrical specifications (330 Ohms ±1%, 2W, ±20ppm/°C, -55°C ~ 150°C) and axial package dimensions (0.180" Dia x 0.449" L) match circuit requirements. The non-inductive feature of WNC330FET may provide additional benefit in high-frequency or sensitive analog circuits.

Q: What is the primary difference between these two part numbers?

A: Both components share identical electrical ratings and physical dimensions. The WNC330FET incorporates non-inductive design characteristics, while the WHC330FET is a standard wirewound configuration. This distinction affects high-frequency performance characteristics.

Q: Are both parts ROHS3 compliant?

A: Yes, both WHC330FET and WNC330FET are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Do these components have identical physical dimensions?

A: Yes, both components share identical axial package dimensions of 0.180" Dia x 0.449" L (4.57mm x 11.40mm), enabling direct mechanical substitution in PCB layouts.

Q: What is the operating temperature range for both parts?

A: Both WHC330FET and WNC330FET operate across the identical temperature range of -55°C to 150°C with a temperature coefficient of ±20ppm/°C.
