WNA1R0FE Equivalent & Substitute Parts

Part Overview

The WNA1R0FE is a 1 Ohm ±1% 0.5W through-hole axial wirewound resistor manufactured by Ohmite. This component is classified as Active product status and is designed for applications requiring non-inductive precision resistance in compact axial packaging. Substitute parts are identified to address packaging variations and inventory availability while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the WNA1R0FE are identified based on electrical equivalence and mechanical compatibility. The primary substitution criterion is packaging format. Both the main part and substitute maintain identical electrical characteristics: 1 Ohm resistance, ±1% tolerance, 0.5W power rating, wirewound non-inductive construction, ±50ppm/°C temperature coefficient, and -55°C to 150°C operating range. The substitute part WNA1R0FET differs only in supplier device packaging (Cut Tape format versus standard packaging), while maintaining the same axial case style, physical dimensions, and all electrical parameters. This substitution is valid for applications where the packaging format does not impose design constraints.

Parameter Comparison

Engineering Selection Recommendations

Both WNA1R0FE and WNA1R0FET are Active status components manufactured by Ohmite within the WN series. Selection between these parts is determined by packaging requirements and supply chain considerations. The WNA1R0FE is available in standard packaging format with 1139 pieces in stock. The WNA1R0FET is supplied in Cut Tape (CT) packaging format with 12852 pieces in stock. Both parts carry identical ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification. For applications where Cut Tape packaging is compatible with assembly processes, WNA1R0FET offers superior inventory availability. For applications requiring standard packaging format, WNA1R0FE remains the primary selection.

Frequently Asked Questions (FAQ)

Q: Can WNA1R0FET be used as a direct replacement for WNA1R0FE?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: WNA1R0FE uses standard packaging while WNA1R0FET uses Cut Tape (CT) packaging. Substitution is valid provided the assembly process accommodates Cut Tape format.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: resistance value (1 Ohm), tolerance (±1%), power rating (0.5W), composition (wirewound), non-inductive feature, temperature coefficient (±50ppm/°C), operating temperature range (-55°C to 150°C), axial package type, and physical dimensions (0.100" Dia x 0.200" L). All parameters must match exactly.

Q: Are there compliance differences between WNA1R0FE and WNA1R0FET?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected status, and EAR99 ECCN classification.

Q: What is the primary reason to consider WNA1R0FET as an alternative?

A: WNA1R0FET offers significantly higher inventory availability (12852 pieces versus 1139 pieces) while maintaining complete electrical and mechanical equivalence. This makes it suitable for high-volume production requirements where Cut Tape packaging is compatible with assembly equipment.

Q: Do these parts have identical physical dimensions?

A: Yes. Both WNA1R0FE and WNA1R0FET have identical axial package dimensions of 0.100" Dia x 0.200" L (2.54mm x 5.08mm), ensuring mechanical interchangeability in PCB layouts and through-hole applications.
