WLCR030FE Equivalent & Substitute Parts

Part Overview

The WLCR030FE is a 30 mOhms ±1% 2W through-hole resistor manufactured by Ohmite in the WL series. This axial wirewound current sense resistor features moisture-resistant construction and is designed for applications requiring precision low-resistance measurements. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified when packaging or inventory considerations necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WLCR030FE is determined by strict equivalence across the following parameters: resistance value (30 mOhms), tolerance (±1%), power rating (2W), composition (wirewound), package type (axial), temperature coefficient (±300ppm/°C), physical dimensions (0.180" Dia x 0.449" L), and feature set (current sense, moisture resistant). The WLCR030FET qualifies as a direct substitute because it maintains identical electrical characteristics and mechanical specifications. The only distinction is packaging format: WLCR030FE is supplied in standard packaging, while WLCR030FET is supplied in cut tape (CT) format. Both parts are manufactured by Ohmite within the WL series and carry Active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both WLCR030FE and WLCR030FET are Active products manufactured by Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability. The WLCR030FE is supplied in standard packaging, while the WLCR030FET is supplied in cut tape format. Both parts maintain ROHS3 compliance and are suitable for current sense applications requiring precision low-resistance measurements with moisture-resistant wirewound construction.

Frequently Asked Questions (FAQ)

Q: Can WLCR030FET replace WLCR030FE in production? A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. WLCR030FET uses cut tape packaging while WLCR030FE uses standard packaging. Selection depends on assembly equipment compatibility and procurement requirements.

Q: Are there any electrical performance differences between these parts? A: No. Both parts share identical resistance (30 mOhms), tolerance (±1%), power rating (2W), temperature coefficient (±300ppm/°C), and feature set (current sense, moisture resistant).

Q: Do both parts meet the same compliance standards? A: Yes. Both WLCR030FE and WLCR030FET are ROHS3 compliant and carry Active product status from Ohmite.

Q: What determines substitutability for this resistor category? A: Substitutability is determined by matching resistance value, tolerance, power rating, composition (wirewound), package type (axial), temperature coefficient, physical dimensions, and feature set. Packaging format does not affect electrical or mechanical compatibility.

Q: Can these parts be used interchangeably in PCB assembly? A: Yes, provided the assembly process can accommodate the packaging format. Both parts have identical axial package dimensions (0.180" Dia x 0.449" L) and termination configuration.
