WLCR025FE Equivalent & Substitute Parts

Part Overview

The WLCR025FE is a 25 mOhms ±1% 2W through-hole resistor manufactured by Ohmite, designed for current sense applications in wirewound axial configuration. This component is classified as Active product status with full ROHS3 compliance. Substitute parts are identified to provide alternative sourcing options while maintaining identical electrical and mechanical specifications for direct circuit board replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WLCR025FE are qualified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires exact matching of:

• Resistance value: 25 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Composition: Wirewound
• Package configuration: Axial
• Physical dimensions: 0.180" Dia x 0.449" L (4.57mm x 11.40mm)
• Temperature coefficient: ±300ppm/°C
• Functional features: Current Sense, Moisture Resistant
• Compliance: ROHS3 Compliant

Only parts meeting all these criteria are listed as direct substitutes. Packaging format differences (such as Cut Tape versus bulk packaging) do not affect electrical or mechanical compatibility and represent alternative procurement options from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

Both WLCR025FE and WLCR025FET are Active status components from Ohmite's WL series with identical electrical specifications and physical dimensions. Selection between these parts is determined by procurement and assembly requirements rather than technical performance:

WLCR025FE is supplied in bulk packaging format, suitable for high-volume manufacturing environments with automated component handling systems.

WLCR025FET is supplied in Cut Tape (CT) packaging format, suitable for lower-volume production runs, manual assembly operations, or applications requiring component-level traceability.

Both parts maintain full ROHS3 compliance and are suitable for current sense applications requiring 25 mOhms resistance at 2W power dissipation with ±1% tolerance and ±300ppm/°C temperature stability.

Frequently Asked Questions (FAQ)

Q: Can WLCR025FET replace WLCR025FE in existing circuit designs?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus bulk). Circuit board layout, thermal performance, and electrical behavior remain unchanged.

Q: What is the significance of the packaging format difference?

A: Packaging format affects procurement logistics and assembly line compatibility. Cut Tape (CT) packaging is used for component-level picking in lower-volume or manual assembly processes. Bulk packaging is optimized for high-speed automated assembly equipment. Electrical and mechanical performance are identical.

Q: Are both parts suitable for current sense applications?

A: Yes. Both WLCR025FE and WLCR025FET are specified with Current Sense and Moisture Resistant features. The 25 mOhms resistance value, ±1% tolerance, and ±300ppm/°C temperature coefficient are standard for precision current sensing circuits.

Q: Do these parts require any special handling or storage considerations?

A: Both parts are classified as Not Applicable for Moisture Sensitivity Level (MSL), indicating standard handling and storage conditions are appropriate. Moisture Resistant composition provides protection in typical industrial environments.

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

A: Both parts share identical axial dimensions of 0.180" diameter by 0.449" length (4.57mm x 11.40mm). Board layout, lead spacing, and mounting hole requirements are identical, enabling direct substitution without PCB redesign.
