WNB1R0FE Equivalent & Substitute Parts

Part Overview

The WNB1R0FE is a 1 Ohm ±1% 1W through-hole axial wirewound resistor manufactured by Ohmite. This non-inductive composition resistor is designed for applications requiring precision resistance values with low inductance characteristics. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified to provide alternative sourcing options while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the WNB1R0FE are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Resistance value: 1 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Composition: Wirewound (exact match required)
• Non-inductive feature: Required
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 150°C (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.130" Dia x 0.276" L (exact match required)
• Compliance certifications: RoHS3 Compliant, REACH Unaffected (exact match required)

Parts meeting all these criteria are classified as direct substitutes. Packaging format variations (such as Cut Tape versus bulk packaging) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both WNB1R0FE and WNB1R0FET are Active status products from Ohmite's WN series with identical electrical specifications and physical dimensions. Selection between these parts is determined by packaging requirements and inventory availability rather than technical performance.

WNB1R0FE is supplied in standard packaging format with 1009 units in stock. WNB1R0FET is supplied in Cut Tape (CT) packaging format with 6301 units in stock. Both parts maintain full RoHS3 compliance and REACH unaffected status, making them suitable for applications with regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can WNB1R0FET replace WNB1R0FE in my circuit?

A: Yes. WNB1R0FET is a direct electrical and mechanical equivalent. Both parts have identical resistance value (1 Ohm), tolerance (±1%), power rating (1W), temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 150°C), and physical dimensions (0.130" Dia x 0.276" L). The only difference is packaging format.

Q: What is the difference between WNB1R0FE and WNB1R0FET?

A: The parts are electrically and mechanically identical. WNB1R0FE uses standard packaging, while WNB1R0FET uses Cut Tape (CT) packaging. This packaging difference affects handling, storage, and automated assembly compatibility but does not affect component performance.

Q: Are both parts RoHS compliant?

A: Yes. Both WNB1R0FE and WNB1R0FET are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What does "non-inductive" mean for this wirewound resistor?

A: Non-inductive wirewound resistors are constructed to minimize parasitic inductance through specialized winding techniques. This characteristic is maintained in both substitute parts and is critical for high-frequency applications where inductance would otherwise degrade circuit performance.

Q: Can I use these resistors in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -55°C to 150°C with a temperature coefficient of ±50ppm/°C, making them suitable for extended temperature range applications within these limits.
