WNB1K0FET Equivalent & Substitute Parts

Part Overview

The WNB1K0FET is a 1 kOhms ±1% 1W through-hole resistor manufactured by Ohmite in axial package configuration. This non-inductive wirewound resistor is designed for applications requiring precision resistance with low inductance characteristics. The part maintains Active product status with 2017 units currently in stock. Substitute parts become necessary when primary inventory is depleted, when supply chain constraints occur, or when design flexibility permits equivalent component selection within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WNB1K0FET is determined by strict equivalence across the following parameters: resistance value (1 kOhms), tolerance (±1%), power rating (1W), composition (wirewound), package type (axial), temperature coefficient (±20ppm/°C), operating temperature range (-55°C ~ 150°C), and physical dimensions (0.130" Dia x 0.276" L). The WHB1K0FET qualifies as a parametric equivalent substitute, meeting all electrical and mechanical requirements while differing only in manufacturer series designation (WH versus WN) and the absence of explicit non-inductive feature documentation.

Parameter Comparison

Engineering Selection Recommendations

Both WNB1K0FET and WHB1K0FET maintain Active product status and full compliance with ROHS3 and REACH regulatory requirements. Selection between these parts should be based on inventory availability and supply chain considerations. The WNB1K0FET currently maintains higher stock levels (2017 units) compared to WHB1K0FET (1623 units). Both components are suitable for direct substitution in applications where the specified electrical parameters and axial package configuration are required. No performance differentiation exists between these parts based on the provided technical specifications.

Frequently Asked Questions (FAQ)

Q: Can WHB1K0FET replace WNB1K0FET in existing designs? A: Yes. Both parts are manufactured by Ohmite with identical electrical specifications (1 kOhms ±1%, 1W wirewound), temperature characteristics (±20ppm/°C, -55°C ~ 150°C), and physical dimensions (0.130" Dia x 0.276" L). The axial package configuration and two-terminal design are identical.

Q: What is the difference between the WN and WH series designations? A: The series designation indicates internal manufacturer product line classification. Both WN and WH series resistors from Ohmite meet the same electrical and mechanical specifications for this 1 kOhms ±1% 1W axial wirewound configuration.

Q: Are there any compliance or certification differences? A: No. Both WNB1K0FET and WHB1K0FET carry identical ROHS3 Compliant and REACH Unaffected certifications.

Q: What is the significance of the non-inductive feature listed for WNB1K0FET? A: The non-inductive designation for WNB1K0FET indicates construction designed to minimize parasitic inductance. This feature is relevant for high-frequency or precision applications. The WHB1K0FET specification does not explicitly document this feature; applications requiring confirmed non-inductive performance should prioritize WNB1K0FET.

Q: Can these parts be used interchangeably in PCB designs? A: Yes, for standard through-hole PCB layouts. Both parts share identical axial package dimensions and two-terminal configuration, requiring no PCB footprint modifications.
