Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WLCR005FE are identified through strict matching of the following critical parameters:

• Resistance value: 5 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Composition: Wirewound
• Package form: 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

The WLCR005FET qualifies as a direct substitute based on identical electrical and mechanical specifications. The difference between these parts is limited to packaging format: the main part uses standard packaging while the substitute is supplied in Cut Tape (CT) format.

Parameter Comparison

Engineering Selection Recommendations

Both WLCR005FE and WLCR005FET are Active products from Ohmite's WL series with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and supply chain considerations. The WLCR005FET in Cut Tape format is suitable for automated assembly processes, while the WLCR005FE standard packaging accommodates manual assembly workflows. Both parts maintain ROHS3 compliance and are suitable for current sense applications requiring precision and moisture resistance.

Frequently Asked Questions (FAQ)

Q: Can WLCR005FET be used as a direct replacement for WLCR005FE?

A: Yes. Both parts are electrically and mechanically identical with matching resistance (5 mOhms), tolerance (±1%), power rating (2W), temperature coefficient (±300ppm/°C), and physical dimensions (0.180" Dia x 0.449" L). The only difference is packaging format.

Q: What is the significance of the "T" designation in WLCR005FET?

A: The "T" suffix indicates Cut Tape (CT) packaging format, which is standard for automated pick-and-place assembly. The base part WLCR005FE uses standard packaging.

Q: Are these parts suitable for high-precision current measurement?

A: Yes. Both parts feature ±1% tolerance and ±300ppm/°C temperature coefficient, meeting precision requirements for current sense applications. The wirewound composition and moisture-resistant construction support reliable performance in demanding environments.

Q: Do both parts meet RoHS requirements?

A: Yes. Both WLCR005FE and WLCR005FET are ROHS3 compliant.

Q: What assembly method should determine part selection?

A: For manual assembly or reel-based processes, use WLCR005FE. For automated assembly lines using tape feeders, use WLCR005FET in Cut Tape format.
