WNB470FE Equivalent & Substitute Parts

Part Overview

The WNB470FE is a 470 Ohms ±1% 1W through-hole resistor manufactured by Ohmite in axial wirewound configuration with non-inductive characteristics. This component is designed for applications requiring precision resistance with low inductance performance across industrial and commercial temperature ranges. The part maintains Active product status with full ROHS3 compliance and REACH unaffected designation. Substitute parts are identified when packaging format differs while maintaining identical electrical and mechanical specifications, enabling procurement flexibility without performance compromise.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WNB470FE is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is packaging format compatibility. The WNB470FE is supplied in standard packaging, while the WNB470FET variant is supplied in Tape & Reel (TR) format. Both parts share identical specifications across resistance value, tolerance, power rating, composition, temperature coefficient, operating temperature range, physical dimensions, and compliance certifications. Substitution is valid when the receiving application accommodates the alternative packaging format without requiring design or assembly process modification.

Parameter Comparison

Engineering Selection Recommendations

Selection between WNB470FE and WNB470FET is determined by procurement and assembly requirements rather than electrical performance. Both parts maintain Active product status with identical ROHS3 compliance and REACH unaffected certifications. The WNB470FE in standard packaging is suitable for low-volume applications, prototype development, and manual assembly processes. The WNB470FET in Tape & Reel format is optimized for high-volume automated assembly operations and continuous production environments. Component selection should align with manufacturing process capability and supply chain logistics. Both variants deliver equivalent electrical performance and thermal characteristics across the specified operating temperature range of -55°C to 150°C.
