Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CME2425-1 are determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Inductance value: 1.05 mH @ 10 kHz
• Current rating: 2.5A maximum
• DC resistance: 50 mOhm maximum
• AC voltage rating: 250V

Mechanical & Physical Specifications:

• Number of lines: 2-line configuration
• Mounting type: Through hole
• Package configuration: Vertical, 4 PC pin
• Physical dimensions: 1.050" L x 1.050" W, 1.075" height maximum

Compliance & Environmental:

• RoHS3 compliance
• Operating temperature range: -40°C ~ 80°C
• Regulatory approvals: CSA, IEC, UL, VDE

Substitute parts must match all parameters listed above. Variations in any electrical, mechanical, or compliance parameter disqualify a part from direct substitution.

Engineering Selection Recommendations

The CME2425-1-B is a direct equivalent substitute for the CME2425-1. Both parts are manufactured by Triad Magnetics within the CME series and share identical electrical, mechanical, and compliance specifications. Selection between these parts may be based on inventory availability and supply chain considerations. The CME2425-1-B currently maintains higher inventory levels (1113 pcs) compared to the CME2425-1 (692 pcs), which may influence procurement decisions. Both parts carry Active product status and maintain full compliance with CSA, IEC, UL, and VDE regulatory requirements, ensuring equivalent performance in power line filtering applications.

Frequently Asked Questions (FAQ)

Q: Can CME2425-1-B be used as a direct replacement for CME2425-1?

A: Yes. The CME2425-1-B is a direct equivalent substitute. All electrical parameters (inductance, current rating, DC resistance, voltage rating), mechanical specifications (dimensions, mounting type, pin configuration), and compliance certifications are identical between the two parts.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: inductance value (1.05 mH @ 10 kHz), current rating (2.5A), DC resistance (50 mOhm), AC voltage rating (250V), operating temperature range (-40°C ~ 80°C), number of lines (2), mounting type (through hole), physical dimensions (1.050" x 1.050" x 1.075" max), package configuration (vertical 4 PC pin), and regulatory approvals (CSA, IEC, UL, VDE).

Q: Are there any differences in packaging or handling between CME2425-1 and CME2425-1-B?

A: Both parts are supplied in bulk packaging. No differences exist in handling, storage, or environmental requirements. Both maintain ROHS3 compliance and are not subject to moisture sensitivity level restrictions.

Q: What is the significance of the "-B" designation in CME2425-1-B?

A: The "-B" designation indicates a variant within the same product line. Despite the designation difference, the CME2425-1-B maintains identical specifications and performance characteristics to the CME2425-1, qualifying it as a direct substitute.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. The CME2425-1 and CME2425-1-B share identical through-hole pin configurations, physical dimensions, and mounting specifications, enabling direct interchangeability in PCB assembly without design modifications.
