CME2425-8 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The CME2425-8 is a 2-line common mode choke manufactured by Triad Magnetics, designed for power line filtering applications. This through-hole component delivers 40.5 mH inductance at 10 kHz with a maximum current rating of 500mA and DC resistance of 1.26Ohm. The part maintains Active product status and carries multiple international approvals including CSA, IEC, UL, and VDE certifications. Substitute parts are identified when electrical specifications, mechanical dimensions, and compliance certifications remain identical across manufacturing batches or variant designations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CME2425-8 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Inductance value (40.5 mH @ 10 kHz), current rating (500mA maximum), and DC resistance (1.26Ohm maximum) must be identical. AC voltage rating (250V) and operating temperature range (-40°C ~ 80°C) must match without deviation.

Mechanical Compatibility: Number of lines (2), mounting type (Through Hole), physical dimensions (1.050" L x 1.050" W, height 1.075"), and package configuration (Vertical, 4 PC Pin) must be identical to ensure PCB layout compatibility.

Compliance & Certification: RoHS3 compliance status and approval agencies (CSA, IEC, UL, VDE) must be maintained. REACH status and ECCN classification must remain unchanged.

Product Status: Only Active status parts qualify as substitutes.

The CME2425-8-B meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both CME2425-8 and CME2425-8-B are Active status components manufactured by Triad Magnetics with identical electrical and mechanical specifications. Selection between these parts is based on inventory availability and supply chain considerations rather than technical differentiation.

CME2425-8 carries 1130 pieces in current inventory stock.

CME2425-8-B carries 1084 pieces in current inventory stock.

Both parts maintain full compliance with CSA, IEC, UL, and VDE approval agencies and satisfy ROHS3 requirements. The identical inductance (40.5 mH @ 10 kHz), current rating (500mA), DC resistance (1.26Ohm), and physical dimensions ensure direct functional and mechanical interchangeability in power line filtering applications requiring 2-line common mode choke configurations.

Frequently Asked Questions (FAQ)

Q: Can CME2425-8-B be used as a direct replacement for CME2425-8?

A: Yes. CME2425-8-B is a direct equivalent with identical electrical specifications (40.5 mH @ 10 kHz, 500mA, 1.26Ohm DCR), mechanical dimensions (1.050" x 1.050" x 1.075"), and compliance certifications (CSA, IEC, UL, VDE, ROHS3).
