WNC100FE Equivalent & Substitute Parts

Part Overview

The WNC100FE is a 100 Ohms ±1% 2W axial wirewound resistor manufactured by Ohmite. This component is currently discontinued at DiGi Electronics but remains available through inventory stock of 960 pieces. The non-inductive wirewound construction makes it suitable for precision applications requiring low inductance characteristics. Due to its discontinued status, identifying equivalent and substitute parts is essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WNC100FE is determined by strict equivalence across the following critical parameters: resistance value (100 Ohms), tolerance (±1%), power rating (2W), composition (wirewound), temperature coefficient (±20ppm/°C), operating temperature range (-55°C to 150°C), package type (axial), and physical dimensions (0.180" Dia × 0.449" L). All identified substitutes maintain these specifications without deviation.

The WNC100FET represents a direct manufacturer equivalent with identical electrical and mechanical characteristics, differentiated only by packaging format (Cut Tape). The WHC100FE qualifies as a parametric equivalent, matching all critical electrical specifications and physical dimensions while belonging to the WH series rather than the WN series.

Parameter Comparison

Engineering Selection Recommendations

The WNC100FET is the primary substitute for the discontinued WNC100FE. Both components are manufactured by Ohmite and maintain identical electrical and mechanical specifications. The WNC100FET carries active product status and is available in higher inventory quantity (1087 pieces), providing superior procurement reliability. The only distinction is packaging format: WNC100FE uses standard packaging while WNC100FET is supplied in Cut Tape format.

The WHC100FE serves as a secondary parametric equivalent. It matches all critical electrical parameters and physical dimensions while belonging to the WH series. This component is also active and maintains equivalent RoHS3 compliance and operating specifications. Selection between WNC100FET and WHC100FE depends on series preference and application-specific requirements, as both satisfy the core electrical and mechanical criteria.

Frequently Asked Questions (FAQ)

Q: Can WNC100FET directly replace WNC100FE in existing designs? A: Yes. The WNC100FET is electrically and mechanically identical to the WNC100FE. The only difference is packaging format (Cut Tape versus standard packaging). No circuit modifications are required.

Q: What is the difference between WNC100FET and WHC100FE? A: Both are parametric equivalents with identical resistance (100 Ohms), tolerance (±1%), power rating (2W), temperature coefficient (±20ppm/°C), operating range (-55°C to 150°C), and physical dimensions. The primary difference is manufacturer series designation (WN versus WH). Both are wirewound axial resistors with equivalent performance characteristics.

Q: Are all substitutes RoHS3 compliant? A: Yes. WNC100FET and WHC100FE both carry ROHS3 Compliant certification, matching the original WNC100FE specification.

Q: Does packaging format affect electrical performance? A: No. Cut Tape packaging (WNC100FET) provides the same electrical characteristics as standard packaging (WNC100FE). Packaging format affects only procurement and handling logistics.

Q: What is the non-inductive feature in the WNC100FE? A: The WNC100FE incorporates non-inductive wirewound construction, which minimizes parasitic inductance. The WHC100FE does not specify this feature in available documentation, though both maintain identical temperature coefficient and operating specifications.

Q: Are there inventory considerations for component selection? A: Current inventory levels are: WNC100FE (960 pieces), WNC100FET (1087 pieces), and WHC100FE (944 pieces). All three options maintain adequate stock for procurement purposes.
