Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CME2425-7 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Inductance value: 27.7 mH @ 10 kHz
• Current rating: 630 mA maximum
• DC resistance: 820 mOhm maximum
• AC voltage rating: 250 V

Mechanical Specifications:

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

Regulatory & Compliance:

• Approval agencies: CSA, IEC, UL, VDE
• RoHS status: ROHS3 Compliant
• Product status: Active

Parts meeting all these criteria are classified as direct substitutes. Variant designations (such as batch codes or packaging identifiers appended to the base part number) do not alter substitution eligibility when core specifications remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

CME2425-7-B is a direct substitute for CME2425-7. Both parts are manufactured by Triad Magnetics and carry identical electrical, mechanical, and regulatory specifications. The "-B" designation represents a variant within the same product line with no functional or performance differences.

Selection between CME2425-7 and CME2425-7-B should be based on inventory availability and lead time requirements. Both parts maintain Active product status and full compliance with CSA, IEC, UL, and VDE standards. The ROHS3 compliance status is identical across both variants, ensuring compatibility with environmental regulations.

For applications requiring 2-line common mode filtering at 630 mA with 27.7 mH inductance and 250 V AC rating, either part number satisfies the design requirements without modification to circuit topology or PCB layout.

Frequently Asked Questions (FAQ)

Q: Can CME2425-7-B replace CME2425-7 in existing designs?

A: Yes. CME2425-7-B is a direct substitute with identical electrical specifications (27.7 mH @ 10 kHz, 630 mA, 820 mOhm DCR), mechanical dimensions (1.050" x 1.050" x 1.075" height), and regulatory approvals (CSA, IEC, UL, VDE). No circuit modifications are required.

Q: What does the "-B" designation indicate?

A: The "-B" suffix represents a variant designation within the CME series. It does not indicate a different electrical performance, current rating, inductance value, or physical form factor. Both CME2425-7 and CME2425-7-B are functionally equivalent.

Q: Are the pin configurations identical?

A: Yes. Both parts use Vertical, 4 PC Pin package configuration with identical through-hole mounting specifications.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both CME2425-7 and CME2425-7-B carry CSA, IEC, UL, and VDE approvals and are ROHS3 compliant.

Q: What is the maximum operating temperature range?

A: Both parts operate across -40°C to 80°C.

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

A: Yes. Identical physical dimensions (1.050" L x 1.050" W, 1.075" maximum height) and through-hole mounting specifications ensure direct PCB compatibility without layout modifications.
