WNBR25FE Equivalent & Substitute Parts

Part Overview

The WNBR25FE is a 250 mOhms ±1% 1W through-hole axial wirewound resistor manufactured by Ohmite. This non-inductive component is designed for applications requiring precision low-resistance values with stable performance across industrial temperature ranges. 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.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WNBR25FE are qualified based on matching the following critical parameters:

• Resistance value: 250 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Non-inductive feature
• Temperature coefficient: ±90ppm/°C
• Operating temperature range: -55°C to 150°C
• Package configuration: Axial
• Physical dimensions: 0.130" Dia x 0.276" L (3.30mm x 7.00mm)
• Termination count: 2
• Compliance certifications: RoHS3, REACH unaffected

The WNBR25FET qualifies as a direct substitute, differing only in packaging format (Cut Tape versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Both WNBR25FE and WNBR25FET are Active status components manufactured by Ohmite within the WN series. Selection between these parts is determined by packaging and supply chain requirements rather than electrical performance.

The WNBR25FE is suitable for standard component procurement workflows. The WNBR25FET, supplied in Cut Tape packaging, is appropriate for automated assembly processes and high-volume production environments where tape-and-reel or cut tape formats are required.

Both parts maintain identical electrical specifications, mechanical dimensions, and regulatory compliance certifications (RoHS3 Compliant, REACH Unaffected). Component selection should be based on assembly process compatibility and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can WNBR25FET replace WNBR25FE in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. WNBR25FET uses Cut Tape packaging while WNBR25FE uses standard packaging. Substitution is valid provided the receiving assembly process accommodates the packaging format.

Q: What determines if a part qualifies as a substitute for WNBR25FE?

A: Substitute parts must match all electrical parameters (250 mOhms resistance, ±1% tolerance, 1W power rating, ±90ppm/°C temperature coefficient), mechanical specifications (axial package, 0.130" Dia x 0.276" L dimensions), composition (wirewound, non-inductive), operating temperature range (-55°C to 150°C), and compliance certifications (RoHS3, REACH unaffected).

Q: Are there inventory differences between WNBR25FE and WNBR25FET?

A: Yes. WNBR25FE has 933 pieces in stock. WNBR25FET has 8397 pieces in stock. Availability may influence sourcing decisions for time-sensitive applications.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape packaging (WNBR25FET) and standard packaging (WNBR25FE) contain identical components. Packaging format affects only handling, storage, and assembly process compatibility.

Q: Are both parts suitable for -55°C to 150°C operating environments?

A: Yes. Both WNBR25FE and WNBR25FET are rated for -55°C to 150°C operation with ±90ppm/°C temperature coefficient stability across this range.
