WNB4R0FE Equivalent & Substitute Parts

Part Overview

The WNB4R0FE is a 4 Ohms ±1% 1W through hole resistor manufactured by Ohmite in the WN series. This axial wirewound resistor features non-inductive construction and operates across a temperature range of -55°C to 150°C. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when packaging configurations differ while maintaining identical electrical and mechanical specifications, enabling procurement flexibility across different assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WNB4R0FE is determined by equivalence across all critical electrical and mechanical parameters: resistance value (4 Ohms), tolerance (±1%), power rating (1W), composition (wirewound), non-inductive feature, temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 150°C), package type (axial), and physical dimensions (0.130" Dia x 0.276" L). The identified substitute part WNB4R0FET maintains complete parity across these parameters. The only distinction is packaging configuration: WNB4R0FE is supplied in standard packaging, while WNB4R0FET is supplied in Tape & Reel (TR) format. Both parts are manufactured by Ohmite within the WN series and carry identical compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both WNB4R0FE and WNB4R0FET are active production parts with identical electrical and mechanical specifications. Selection between these parts is determined by assembly process requirements and packaging logistics. The WNB4R0FE in standard packaging is suitable for manual assembly, prototyping, and low-volume applications. The WNB4R0FET in Tape & Reel format is optimized for automated pick-and-place assembly and high-volume production environments. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across manufacturing contexts.

Frequently Asked Questions (FAQ)
