WNB1K0FE Equivalent & Substitute Parts

Part Overview

The WNB1K0FE is a 1 kOhms ±1% 1W through-hole resistor manufactured by Ohmite in the WN series. This axial wirewound resistor features non-inductive construction and operates across -55°C to 150°C. The part is Active status and ROHS3 compliant. Substitute parts are identified when inventory constraints, packaging requirements, or series transitions necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: resistance value (1 kOhms), tolerance (±1%), power rating (1W), composition (wirewound), package type (axial), physical dimensions (0.130" Dia x 0.276" L), temperature coefficient (±20ppm/°C), operating temperature range (-55°C ~ 150°C), and regulatory compliance (ROHS3). Parts are grouped into two categories:

Direct Manufacturer Substitutes: Parts from the same manufacturer (Ohmite) with identical electrical specifications and axial package configuration. These differ only in packaging format (Cut Tape vs. bulk).

Parametric Equivalents: Parts from the same manufacturer matching all electrical and mechanical parameters but from different series designations. These maintain full functional compatibility while offering alternative sourcing options.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment for current designs. WNB1K0FET offers the same electrical and mechanical specifications as WNB1K0FE with Cut Tape packaging, suitable for automated assembly environments. WHB1K0FE provides parametric equivalence from the WH series, maintaining all critical electrical parameters and axial package dimensions while representing an alternative series option from Ohmite. Selection between these parts should be based on packaging requirements, inventory availability, and assembly process compatibility rather than electrical performance, as all three deliver identical functional characteristics within the specified operating envelope.

Frequently Asked Questions (FAQ)

Q: Can WNB1K0FET be used as a direct replacement for WNB1K0FE? A: Yes. WNB1K0FET is electrically and mechanically identical to WNB1K0FE. The difference is packaging format: WNB1K0FE is supplied in bulk, while WNB1K0FET is supplied in Cut Tape. Both are suitable for through-hole assembly.

Q: What is the difference between WNB1K0FE and WHB1K0FE? A: Both parts are parametric equivalents with identical resistance (1 kOhms), tolerance (±1%), power rating (1W), temperature coefficient (±20ppm/°C), operating range (-55°C ~ 150°C), and axial package dimensions. The primary difference is series designation: WNB1K0FE belongs to the WN series with non-inductive features specified, while WHB1K0FE belongs to the WH series without non-inductive specification listed.

Q: Are all three parts suitable for the same PCB layout? A: Yes. All three parts share identical axial package dimensions (0.130" Dia x 0.276" L / 3.30mm x 7.00mm) and two terminations, making them mechanically interchangeable on PCB layouts designed for axial through-hole resistors.

Q: Do these parts meet current regulatory requirements? A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component sourcing.

Q: Which part should be selected for automated assembly? A: WNB1K0FET is optimized for automated assembly due to its Cut Tape packaging format, which integrates directly with pick-and-place equipment.
