Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WLAR010FE are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters:

• Resistance value: 10 mOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Wirewound
• Package configuration: Axial through-hole
• Physical dimensions: 0.100" Dia x 0.200" L (2.54mm x 5.08mm)
• Temperature coefficient: ±300ppm/°C
• Functional features: Current sense and moisture resistance capability
• Compliance: ROHS3 Compliant

Parts meeting all these criteria are classified as direct equivalents and may be substituted without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

Both WLAR010FE and WLAR010FET are Active status components manufactured by Ohmite with identical electrical specifications and physical dimensions. The primary distinction is packaging format: WLAR010FE is supplied in standard packaging, while WLAR010FET is supplied in Cut Tape (CT) format. Both parts maintain ROHS3 compliance and are suitable for current sense applications requiring moisture resistance. Selection between these parts should be based on procurement requirements and assembly process compatibility with the available packaging format.

Frequently Asked Questions (FAQ)

Q: Can WLAR010FET be used as a direct replacement for WLAR010FE?

A: Yes. Both parts are manufactured by Ohmite with identical electrical and mechanical specifications, including resistance value, tolerance, power rating, physical dimensions, and temperature coefficient. The only difference is packaging format (Cut Tape versus standard packaging).

Q: What is the significance of the packaging difference between these parts?

A: WLAR010FE uses standard packaging, while WLAR010FET uses Cut Tape (CT) format. This distinction affects procurement and assembly processes but does not impact electrical performance or board-level compatibility once the component is installed.

Q: Are both parts suitable for current sense applications?

A: Yes. Both WLAR010FE and WLAR010FET are specified with current sense functionality and moisture resistance, making them appropriate for current sensing circuits in industrial and commercial applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8533.21.0080).

Q: What is the temperature coefficient specification, and why is it important?

A: Both parts have a temperature coefficient of ±300ppm/°C. This specification indicates the resistance change per degree Celsius and is critical for applications requiring stable performance across varying operating temperatures.
