Engineering Selection Recommendations

CMT-8106 (Triad Magnetics):

  • Active product status with established supply (856 pcs in stock)
  • Approved by CSA, IEC, UL, and VDE certification bodies
  • Suitable for applications requiring multiple regulatory approvals
  • Recommended for designs with existing Triad Magnetics component qualification

8106-RC (Bourns Inc.):

  • Active product status with higher inventory availability (1,780 pcs in stock)
  • RoHS3 and REACH compliant
  • Identical electrical and mechanical specifications to CMT-8106
  • Recommended for applications where supply continuity or inventory availability is a priority
  • Suitable as a direct replacement in existing designs using CMT-8106

Both parts meet identical functional requirements for 2-line common mode choke applications in power line filtering. Selection between them should be based on procurement availability, existing supplier relationships, and regulatory certification requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the 8106-RC directly replace the CMT-8106 on a PCB?

A: Yes. Both parts share identical electrical specifications (5 mH @ 1 kHz, 3.7A, 70 mOhm DCR), operating temperature range (-55°C to 105°C), and mechanical dimensions (1.200" L x 0.600" W, 1.200" height). The through-hole, vertical 4-pin package configuration is identical, enabling direct PCB footprint compatibility.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The CMT-8106 carries additional certifications (CSA, IEC, UL, VDE), while the 8106-RC does not list specific approval agencies in the provided data. Applications requiring specific regulatory approvals should verify certification requirements against the CMT-8106's documented approvals.

Q: What is the difference between the CMT-8106 and 8106-RC part numbers?

A: The CMT-8106 is manufactured by Triad Magnetics under the CMT series. The 8106-RC is manufactured by Bourns Inc. under the 8100 series. Despite different manufacturers and series designations, both parts meet identical electrical and mechanical specifications for 2-line common mode choke applications.

Q: Which part should I select for new designs?

A: Selection depends on procurement strategy and regulatory requirements. For designs requiring multiple regulatory certifications (CSA, IEC, UL, VDE), the CMT-8106 is appropriate. For designs where supply availability and inventory are priorities, the 8106-RC offers higher stock levels (1,780 pcs vs. 856 pcs). Both parts are active products suitable for new production.

Q: Are the DC resistance values identical?

A: Yes. Both the CMT-8106 and 8106-RC specify a maximum DC resistance of 70 mOhm, ensuring equivalent power dissipation and thermal performance in power line filtering circuits.

Q: Can these parts be used interchangeably in existing production?

A: Yes, provided that the application does not require specific regulatory certifications beyond RoHS3 and REACH compliance. If the original design specifies CMT-8106 with particular approval agencies (CSA, IEC, UL, VDE), design verification should confirm that the 8106-RC meets those same certification requirements before substitution in production.
