WLBR050FE Equivalent & Substitute Parts

Part Overview

The WLBR050FE is a 50 mOhms ±1% 1W through-hole resistor in axial package manufactured by Ohmite. This wirewound current sense resistor is designed for precision low-resistance applications requiring moisture resistance. The part is Active status and ROHS3 compliant. Substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WLBR050FE is determined by matching the following critical parameters:

• Resistance value: 50 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package/Case: Axial
• Temperature coefficient: ±100ppm/°C
• Features: Current Sense, Moisture Resistant
• Physical dimensions: 0.130" Dia x 0.276" L (3.30mm x 7.00mm)
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant

The WLBR050FET qualifies as a direct substitute. Both parts are manufactured by Ohmite, share identical electrical and mechanical specifications, and differ only in packaging configuration (bulk versus cut tape). This packaging difference does not affect electrical performance or mechanical fit in applications.

Parameter Comparison

Engineering Selection Recommendations

Both WLBR050FE and WLBR050FET are Active status components manufactured by Ohmite with identical electrical and mechanical specifications. Selection between these parts is determined by procurement and assembly requirements:

• WLBR050FE: Bulk packaging suitable for high-volume manual assembly or reel-fed automated processes
• WLBR050FET: Cut tape packaging suitable for lower-volume applications or mixed-component assembly runs

Both parts maintain ROHS3 compliance and are suitable for current sense applications requiring precision low-resistance measurement. No electrical performance difference exists between the two packaging configurations.

Frequently Asked Questions (FAQ)

Q: Can WLBR050FET replace WLBR050FE in production?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. WLBR050FET uses cut tape packaging while WLBR050FE uses bulk packaging. Assembly equipment compatibility should be verified based on your specific process requirements.

Q: Are the physical dimensions identical between WLBR050FE and WLBR050FET?

A: Yes. Both parts measure 0.130" diameter by 0.276" length (3.30mm x 7.00mm). PCB footprint and mounting requirements are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both WLBR050FE and WLBR050FET are ROHS3 compliant with identical electrical specifications including ±1% tolerance, 1W power rating, and ±100ppm/°C temperature coefficient.

Q: What is the primary reason to substitute between these parts?

A: Packaging availability and supply chain requirements. Both parts are manufactured by Ohmite with identical performance characteristics. Substitution is driven by inventory status and assembly process compatibility rather than electrical or mechanical differences.
