Engineering Selection Recommendations

The CME375-7 and CME375-7-B are functionally equivalent components suitable for direct substitution in power line common mode choke applications. Both parts maintain Active product status from Triad Magnetics and carry identical international certifications (CSA, IEC, UL, VDE), confirming compliance with applicable safety and performance standards.

Selection between these parts should be based on availability and inventory status. The CME375-7 currently maintains 889 pieces in stock, while the CME375-7-B maintains 830 pieces in stock. Both parts are supplied in Bulk packaging and are ROHS3 Compliant with REACH Unaffected status, meeting environmental regulatory requirements.

For applications requiring 70.3 mH inductance at 10 kHz with 1.38A current capacity and 785mOhm DC resistance in a through-hole vertical configuration, either part number provides identical electrical and mechanical performance. PCB layout and mechanical mounting considerations remain unchanged between these parts due to identical physical dimensions and pin configuration.

Frequently Asked Questions (FAQ)

Q: Can CME375-7-B be used as a direct replacement for CME375-7?

A: Yes. The CME375-7-B is a direct equivalent substitute. All electrical parameters (inductance, current rating, DC resistance, voltage rating, temperature range) and mechanical parameters (dimensions, mounting type, pin configuration) are identical between both parts.

Q: Are there any differences in certifications or compliance between these parts?

A: No. Both CME375-7 and CME375-7-B carry identical approvals from CSA, IEC, UL, and VDE. Both parts are ROHS3 Compliant and REACH Unaffected, meeting the same regulatory requirements.

Q: What determines whether a part can substitute for the CME375-7?

A: Substitution is determined by exact equivalence in inductance value (70.3 mH @ 10 kHz), current rating (1.38A), DC resistance (785mOhm), AC voltage rating (250V), operating temperature range (-40°C to 80°C), mounting type (Through Hole), package configuration (Vertical, 4 PC Pin), and physical dimensions (1.500" L x 1.260" W x 1.180" H).

Q: Will the CME375-7-B fit in the same PCB footprint as the CME375-7?

A: Yes. Both parts have identical physical dimensions of 1.500" L x 1.260" W (38.10mm x 32.00mm) with maximum height of 1.180" (29.97mm). The package configuration is Vertical, 4 PC Pin for both parts, ensuring identical PCB mounting compatibility.

Q: Are there any performance differences between CME375-7 and CME375-7-B?

A: No. Both parts are from the same CME series manufactured by Triad Magnetics and provide identical electrical performance specifications. DC resistance, inductance, current handling, and voltage ratings are equivalent.

Q: What is the difference between these part numbers?

A: The CME375-7-B designation indicates a variant within the CME375 product line. However, all specified electrical and mechanical parameters remain identical to the CME375-7, making them functionally interchangeable for circuit design and application purposes.
