Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CME2425-2 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Inductance value of 2.37 mH measured at 10 kHz, maximum current rating of 2A, and DC resistance not exceeding 80 mOhm must be maintained. AC voltage rating of 250V is required for power line filtering applications.

Mechanical Specifications: Through-hole mounting configuration with vertical orientation and 4-pin package is mandatory for PCB compatibility. Physical dimensions of 1.050" L x 1.050" W with maximum height of 1.075" ensure proper board layout and thermal management.

Environmental & Compliance: Operating temperature range of -40°C to 80°C and ROHS3 compliance are required. Approval by CSA, IEC, UL, and VDE certifications must be maintained.

Filter Classification: 2-line common mode choke configuration for power line filtering applications.

Parts meeting all these criteria are classified as direct substitutes and are electrically and mechanically interchangeable.

Parameter Comparison

Engineering Selection Recommendations

Both CME2425-2 and CME2425-2-B are Active product status components manufactured by Triad Magnetics with identical electrical, mechanical, and compliance specifications. Selection between these parts is based on inventory availability and procurement lead times rather than technical differentiation.

The CME2425-2 maintains 948 pieces in current stock inventory. The CME2425-2-B variant maintains 1189 pieces in current stock inventory, providing higher availability for immediate procurement requirements.

Both parts carry full compliance with CSA, IEC, UL, and VDE approval agencies, ensuring suitability for regulated power line filtering applications. ROHS3 compliance is maintained across both variants, meeting environmental and regulatory requirements for commercial and industrial deployment.

No technical re-qualification is required when transitioning between these parts, as all electrical performance parameters, thermal characteristics, and mechanical interfaces are identical.

Frequently Asked Questions (FAQ)

Q: Are CME2425-2 and CME2425-2-B electrically interchangeable?

A: Yes. Both parts feature identical inductance values of 2.37 mH at 10 kHz, current ratings of 2A, and DC resistance of 80 mOhm. Electrical performance in power line filtering applications is equivalent.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts share identical through-hole mounting configurations, vertical orientation, 4-pin package design, and physical dimensions of 1.050" L x 1.050" W x 1.075" H. Direct PCB substitution is supported without layout modifications.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is determined by matching inductance (2.37 mH @ 10 kHz), current rating (2A), DC resistance (80 mOhm), AC voltage rating (250V), operating temperature range (-40°C to 80°C), mounting type (through-hole), physical dimensions, and compliance certifications (CSA, IEC, UL, VDE).

Q: Do both parts meet the same regulatory approvals?

A: Yes. Both CME2425-2 and CME2425-2-B carry identical approvals from CSA, IEC, UL, and VDE, and both are ROHS3 compliant.

Q: Which part should be selected based on availability?

A: CME2425-2-B currently maintains higher inventory (1189 pieces) compared to CME2425-2 (948 pieces). Selection should be based on procurement timeline and inventory requirements, as both parts are technically equivalent.

Q: Are there any thermal or environmental differences between these parts?

A: No. Both parts operate across the identical temperature range of -40°C to 80°C and maintain equivalent thermal performance characteristics for power line filtering applications.
