Ohmite WNC10RFE Equivalent & Substitute Parts

Part Overview

The Ohmite WNC10RFE is a 10 Ohm ±1% 2W axial wirewound resistor with non-inductive characteristics. This component is discontinued at DiGi Electronics, necessitating identification of equivalent alternatives for ongoing production and maintenance applications. Substitute parts maintain identical electrical specifications and mechanical form factors while offering improved availability or alternative packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WNC10RFE is determined by strict equivalence across the following parameters: resistance value (10 Ohms), tolerance (±1%), power rating (2W), composition (wirewound), package type (axial), temperature coefficient (±50ppm/°C), operating temperature range (-55°C to 150°C), and physical dimensions (0.180" Dia × 0.449" L). Parts meeting all these criteria are classified as direct or parametric equivalents.

Direct Substitute: WNC10RFET maintains identical specifications with alternative packaging (Cut Tape) and active product status.

Parametric Equivalent: WHC10RFE meets all electrical and mechanical parameters but belongs to the WH series. The non-inductive feature specification differs; however, this does not affect functional equivalence for standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

WNC10RFET is the primary substitute for WNC10RFE. Both parts are manufactured by Ohmite with identical electrical and mechanical specifications. WNC10RFET carries active product status and is available in Cut Tape packaging, providing superior supply chain continuity. ROHS3 compliance and REACH unaffected status are maintained.

WHC10RFE serves as a parametric equivalent when WNC10RFET availability is constrained. The WHC series designation indicates alternative internal construction; however, all critical electrical parameters and physical form factor remain equivalent. WHC10RFE is active and maintains full regulatory compliance.

Selection between WNC10RFET and WHC10RFE should prioritize WNC10RFET for direct replacement applications. WHC10RFE is suitable for new designs or applications where series consistency is not a requirement.

Frequently Asked Questions (FAQ)

Q: Can WNC10RFET directly replace WNC10RFE in existing designs? A: Yes. WNC10RFET is a direct substitute with identical electrical specifications (10 Ohms ±1%, 2W), temperature characteristics (±50ppm/°C, -55°C to 150°C), and axial package dimensions (0.180" Dia × 0.449" L). The only difference is packaging format (Cut Tape versus bulk) and active product status.

Q: What is the difference between WNC10RFET and WHC10RFE? A: Both are parametric equivalents meeting all electrical and mechanical requirements. WNC10RFET belongs to the WN series with non-inductive specification; WHC10RFE belongs to the WH series without specified non-inductive features. For applications requiring non-inductive characteristics, WNC10RFET is preferred.

Q: Are all substitute parts ROHS3 compliant? A: Yes. WNC10RFET and WHC10RFE are both ROHS3 compliant and REACH unaffected, matching the compliance status of WNC10RFE.

Q: Does packaging format affect electrical performance? A: No. WNC10RFET supplied in Cut Tape (CT) packaging delivers identical electrical performance to bulk-packaged WNC10RFE. Packaging format affects only handling, storage, and assembly processes.

Q: Can WHC10RFE be used in applications requiring non-inductive performance? A: WHC10RFE specifications do not explicitly include non-inductive features. For circuits where non-inductive characteristics are critical, WNC10RFET is the appropriate selection.
