Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WLAR050FE is determined by strict equivalence across the following critical parameters:

• Resistance value: 50 mOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Wirewound
• Package case: Axial
• Physical dimensions: 0.100" Dia x 0.200" L (2.54mm x 5.08mm)
• Temperature coefficient: ±100ppm/°C
• Features: Current Sense, Moisture Resistant
• Compliance: ROHS3 Compliant

The WLAR050FET is classified as a direct substitute, differing only in packaging format (Cut Tape versus standard packaging). Both parts maintain identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both WLAR050FE and WLAR050FET are Active status components with full ROHS3 compliance. Selection between these parts is determined by packaging requirements and supply chain considerations. The WLAR050FE is available in standard packaging format, while WLAR050FET is supplied in Cut Tape format. Both parts are electrically and mechanically identical, with no performance differentiation. Component selection should be based on assembly process compatibility and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can WLAR050FET be used as a direct replacement for WLAR050FE?

A: Yes. Both parts are electrically and mechanically equivalent. The only difference is packaging format: WLAR050FE uses standard packaging while WLAR050FET is supplied in Cut Tape format. Axial package dimensions and all electrical specifications are identical.

Q: What is the primary application for these resistors?

A: These components are designed for current sense applications. The 50 mOhm resistance value and wirewound composition provide precision measurement capability with moisture resistance in demanding environments.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both WLAR050FE and WLAR050FET carry identical ROHS3 compliance certification and share the same ECCN and HTSUS classifications.

Q: How does packaging format affect component selection?

A: Packaging format impacts assembly automation compatibility and handling procedures. Cut Tape format (WLAR050FET) is optimized for automated pick-and-place equipment, while standard packaging (WLAR050FE) may be preferred for manual assembly or specific storage requirements. Electrical and mechanical performance remains unchanged.

Q: What tolerance specification applies to these resistors?

A: Both parts maintain ±1% tolerance on the 50 mOhm resistance value, ensuring precision in current sensing circuits where measurement accuracy is critical.
