WNBR10FE Equivalent & Substitute Parts

Part Overview

The WNBR10FE is a 100 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 when packaging or inventory requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The WNBR10FET qualifies as a direct substitute for the WNBR10FE based on identical electrical and mechanical parameters. Substitution criteria are strictly limited to the following verified parameters:

• Resistance value: 100 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Non-inductive feature set
• Temperature coefficient: ±90ppm/°C
• Operating temperature range: -55°C to 150°C
• Package configuration: Axial
• Physical dimensions: 0.130" Dia × 0.276" L (3.30mm × 7.00mm)
• Number of terminations: 2
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The only distinction between the main part and substitute is packaging format: WNBR10FE is supplied in standard packaging, while WNBR10FET is supplied in Cut Tape (CT) format. Both parts are manufactured by Ohmite and maintain Active product status.

Parameter Comparison

Engineering Selection Recommendations

Both WNBR10FE and WNBR10FET are suitable for applications requiring 100 mOhms ±1% 1W axial wirewound resistors. Selection between these parts should be based on procurement and assembly requirements:

WNBR10FE is appropriate for applications where standard packaging format is specified or preferred for manual assembly or kit-based applications.

WNBR10FET is appropriate for high-volume automated assembly operations utilizing tape-and-reel feeding systems, as Cut Tape packaging is optimized for pick-and-place equipment.

Both parts maintain identical electrical performance, mechanical compatibility, and regulatory compliance. The choice between them does not affect circuit functionality or reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can WNBR10FET be used as a direct replacement for WNBR10FE in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. WNBR10FET in Cut Tape format is compatible with automated assembly equipment, while WNBR10FE in standard packaging is suitable for manual or semi-automated assembly.

Q: Are there any performance differences between WNBR10FE and WNBR10FET?

A: No. Both parts share identical electrical specifications including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. Performance in circuit applications is equivalent.

Q: What does Cut Tape (CT) packaging mean for WNBR10FET?

A: Cut Tape packaging supplies components on carrier tape in cut lengths rather than full reels. This format is designed for automated pick-and-place assembly systems and is commonly used in high-volume manufacturing environments.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both WNBR10FE and WNBR10FET are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Q: What is the physical size compatibility between these parts?

A: Both parts have identical axial dimensions of 0.130" diameter × 0.276" length (3.30mm × 7.00mm). They are mechanically interchangeable on PCBs designed for standard axial component mounting.
