WNC5R0FE Equivalent & Substitute Parts

Part Overview

The WNC5R0FE is a 5 Ohm, 1% tolerance, 2W axial wirewound resistor manufactured by Ohmite. This non-inductive through-hole component is designed for applications requiring precision resistance with low inductance characteristics. The part is currently discontinued at DiGi Electronics, making substitute parts necessary for ongoing production and maintenance applications. Alternative equivalent parts maintain identical electrical specifications while offering different packaging or availability options.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WNC5R0FE are qualified based on matching the following critical parameters: resistance value (5 Ohms), tolerance (±1%), power rating (2W), composition (wirewound), temperature coefficient (±50ppm/°C), operating temperature range (-55°C to 150°C), package type (axial), and physical dimensions (0.180" Dia x 0.449" L). Parts are grouped into two categories: direct manufacturer substitutes and parametric equivalents. Direct substitutes maintain all electrical and mechanical specifications with variations only in packaging format or product status. Parametric equivalents meet all core electrical requirements but may differ in secondary features such as non-inductive designation.

Parameter Comparison

Engineering Selection Recommendations

WNC5R0FET is the primary direct substitute for WNC5R0FE. Both parts are manufactured by Ohmite and share identical electrical and mechanical specifications. The WNC5R0FET differs only in packaging format (Cut Tape) and maintains active product status with higher inventory availability (10,591 pcs). This part is suitable for direct replacement in all applications where the original WNC5R0FE was specified.

WHC5R0FE serves as a parametric equivalent from the Ohmite WH series. It matches all core electrical parameters and physical dimensions. The primary distinction is the absence of explicit non-inductive designation in the feature set, though the wirewound construction and specifications remain consistent with the original part. This part is also active and available (904 pcs in stock).

All substitute options maintain ROHS3 compliance and identical operating temperature ranges, ensuring regulatory and thermal compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can WNC5R0FET be used as a direct replacement for WNC5R0FE? A: Yes. WNC5R0FET is a direct substitute with identical electrical specifications (5 Ohms, ±1%, 2W), composition (wirewound), temperature coefficient (±50ppm/°C), operating range (-55°C to 150°C), and physical dimensions (0.180" Dia x 0.449" L). The only difference is packaging format (Cut Tape vs. bulk).

Q: What is the difference between WNC5R0FET and WHC5R0FE? A: Both are parametric equivalents with matching resistance, tolerance, power rating, temperature coefficient, and operating range. WNC5R0FET is from the WN series and explicitly features non-inductive construction. WHC5R0FE is from the WH series without explicit non-inductive designation. Both are wirewound axial resistors with identical physical dimensions.

Q: Are all substitute parts ROHS3 compliant? A: Yes. WNC5R0FE, WNC5R0FET, and WHC5R0FE are all ROHS3 compliant, ensuring compatibility with regulatory requirements.

Q: Does packaging format affect electrical performance? A: No. WNC5R0FET uses Cut Tape packaging while WNC5R0FE uses standard packaging. Packaging format does not affect electrical characteristics, only handling and supply method.

Q: Can these parts be used in high-temperature applications? A: Yes. All substitute parts operate across the range -55°C to 150°C, supporting both industrial and high-temperature applications within this specification.
