WNB5R0FET Equivalent & Substitute Parts

Part Overview

The WNB5R0FET is a 5 Ohm ±1% 1W through-hole axial wirewound resistor manufactured by Ohmite, currently in active production status. This non-inductive wirewound resistor is designed for applications requiring precision resistance values with low inductance characteristics. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from equivalent alternatives within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WNB5R0FET is determined by strict equivalence across the following parameters:

• Resistance value: 5 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 150°C
• Physical dimensions: 0.130" Dia × 0.276" L (3.30mm × 7.00mm)
• Termination count: 2
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The WHB5R0FET meets all electrical and mechanical substitution criteria, differing only in series designation (WH versus WN) while maintaining identical performance specifications and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both WNB5R0FET and WHB5R0FET are active production components manufactured by Ohmite with identical electrical specifications and physical form factors. Selection between these parts is based on availability and supply chain considerations rather than technical performance differences. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications. The WHB5R0FET currently maintains higher inventory levels (12,465 pcs versus 1,878 pcs), making it suitable for applications where supply continuity is a priority.

Frequently Asked Questions (FAQ)

Q: Can WHB5R0FET be used as a direct replacement for WNB5R0FET?

A: Yes. Both parts are manufactured by Ohmite with identical electrical specifications (5 Ohms ±1%, 1W), identical temperature characteristics (±50ppm/°C, -55°C to 150°C operating range), and identical physical dimensions (0.130" Dia × 0.276" L). The series designation difference (WH versus WN) does not affect functional equivalence.

Q: Are there any differences in the non-inductive feature between these parts?

A: The WNB5R0FET is explicitly specified as non-inductive wirewound. The WHB5R0FET specification does not include this feature designation. For applications requiring confirmed non-inductive characteristics, the WNB5R0FET remains the specified choice.

Q: Do both parts fit the same PCB footprint?

A: Yes. Both parts share identical axial package dimensions of 0.130" Dia × 0.276" L (3.30mm × 7.00mm) with 2 terminations, ensuring mechanical and electrical compatibility in the same through-hole mounting configuration.

Q: What is the difference between the WN and WH series?

A: The WN and WH series are distinct product lines from Ohmite with identical electrical and mechanical specifications for this 5 Ohm 1W axial resistor. Series designation reflects internal manufacturing or product line organization but does not indicate performance differences.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both WNB5R0FET and WHB5R0FET are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use.
