Key Parameters

Substitute Part Grouping Explanation

Substitution of the CME2425-4 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value: 6 mH @ 10 kHz
• Current rating: 1.28A maximum
• DC resistance: 202mOhm maximum
• AC voltage rating: 250V
• Operating temperature range: -40°C to 80°C minimum

Mechanical Equivalence Criteria:

• Mounting type: Through Hole
• Package configuration: Vertical, 4 PC Pin
• Physical dimensions: 1.050" L x 1.050" W (26.67mm x 26.67mm)
• Maximum height: 1.075" (27.31mm)

Compliance Equivalence Criteria:

• Manufacturer series: CME
• Product status: Active
• Regulatory approvals: CSA, IEC, UL, VDE
• RoHS3 compliance
• REACH unaffected status

Substitute parts must match all three equivalence categories without exception.

Parameter Comparison

Engineering Selection Recommendations

The CME2425-4-B is a direct equivalent substitute for the CME2425-4. Both components are manufactured by Triad Magnetics within the CME series and maintain identical electrical specifications, mechanical dimensions, and regulatory compliance status.

Selection Basis:

Both parts carry Active product status and hold equivalent international certifications (CSA, IEC, UL, VDE), ensuring compliance with applicable power line filtering standards. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing.

The identical inductance value of 6 mH @ 10 kHz, current rating of 1.28A, and DC resistance of 202mOhm ensure functional equivalence in power line filtering applications. The matching through-hole mounting configuration with vertical 4-pin package and identical physical dimensions (1.050" L x 1.050" W, 27.31mm maximum height) confirm mechanical interchangeability without PCB redesign.

Selection between CME2425-4 and CME2425-4-B may be based on inventory availability, lead time, or procurement source, as no technical differentiation exists between the two parts.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the CME2425-4?

A: A substitute part must match all electrical parameters (6 mH inductance @ 10 kHz, 1.28A current rating, 202mOhm DC resistance, 250V AC rating), maintain the same operating temperature range (-40°C to 80°C), use identical through-hole mounting with vertical 4-pin package configuration, and maintain the same physical dimensions (1.050" L x 1.050" W, 27.31mm maximum height). The part must also retain Active product status and equivalent regulatory approvals.

Q: Is the CME2425-4-B a direct replacement for the CME2425-4?

A: Yes. The CME2425-4-B meets all electrical, mechanical, and compliance equivalence criteria. Both parts are manufactured by Triad Magnetics within the CME series and share identical specifications across all critical parameters.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. Both the CME2425-4 and CME2425-4-B share identical through-hole mounting configuration, package type (vertical 4-pin), and physical dimensions. No PCB modification is required for substitution.

Q: What is the significance of the "4 PC Pin" package designation?

A: The "4 PC Pin" designation indicates a four-pin through-hole package configuration used for two-line common mode choke applications. This package type is standard for power line filtering components and ensures compatibility with standard PCB footprints designed for this component category.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the CME2425-4 and CME2425-4-B are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What regulatory approvals do these parts carry?

A: Both parts carry approvals from CSA, IEC, UL, and VDE, confirming compliance with international power line filtering and electromagnetic compatibility standards.
