Parameter Comparison

Engineering Selection Recommendations

All three parts—CME375-5, CME375-5-B, and CME375-4—are classified as Active products with identical electrical specifications, mechanical dimensions, and compliance certifications. Selection between these parts is based on availability and inventory status:

CME375-5: 854 pieces in stock. Primary selection for new designs and standard procurement.

CME375-5-B: 771 pieces in stock. Direct substitute with identical specifications. Suitable for applications requiring alternative sourcing or when primary part availability is limited.

CME375-4: 701 pieces in stock. Parametric equivalent with identical electrical and mechanical characteristics. Suitable for applications where part number variation within the CME series is acceptable.

All three parts carry full international compliance certifications (CSA, IEC, UL, VDE) and ROHS3 compliance status, confirming suitability for regulated applications. Through-hole mounting configuration and vertical 4-pin package ensure consistent PCB integration across all three options.

Frequently Asked Questions (FAQ)

Q: Can CME375-5-B be used as a direct replacement for CME375-5?

A: Yes. CME375-5-B is a direct substitute with identical electrical parameters (17.8 mH @ 10 kHz, 2.7A, 196 mOhm DCR), mechanical dimensions (1.500" L x 1.260" W, 1.180" height), mounting type (through-hole, vertical 4-pin), and compliance certifications (CSA, IEC, UL, VDE, ROHS3).

Q: What is the difference between CME375-5 and CME375-4?

A: Both parts are parametric equivalents within the CME series. All electrical specifications, physical dimensions, mounting configuration, and compliance certifications are identical. The part number variation reflects internal Triad Magnetics product line designation but does not affect functional performance or interchangeability.

Q: Are all three parts suitable for 250V AC applications?

A: Yes. All three parts—CME375-5, CME375-5-B, and CME375-4—are rated for 250V AC operation and carry identical voltage specifications.

Q: Do these parts require any special handling or storage considerations?

A: Moisture Sensitivity Level (MSL) is Not Applicable for all three parts, indicating standard handling and storage procedures are sufficient. No special environmental controls are required.

Q: Can these parts be used in applications operating at -40°C to 80°C?

A: Yes. All three parts maintain their specified electrical characteristics across the full operating temperature range of -40°C to 80°C.

Q: Are all three parts ROHS3 compliant?

A: Yes. CME375-5, CME375-5-B, and CME375-4 are all ROHS3 compliant and REACH unaffected, confirming suitability for regulated markets and environmentally controlled applications.

Q: What is the maximum current these parts can handle?

A: All three parts are rated for a maximum continuous current of 2.7A with a DC resistance of 196 mOhm.
