Frequently Asked Questions (FAQ)

Q: What makes the Adam Tech MTD-A-05-E-2 a direct substitute for the TE Connectivity 3-643828-5?

A: Both connectors share identical specifications across all critical parameters: 5-position receptacle configuration, 0.100" pitch, IDC termination for 26 AWG wire, tin contact finish, closed end design, and locking ramp fastening. These parameters define functional and mechanical compatibility for direct replacement.

Q: Are there differences in contact finish thickness between these parts?

A: The TE Connectivity 3-643828-5 specifies a contact finish thickness of 80.0µin (2.03µm). The Adam Tech MTD-A-05-E-2 does not provide contact finish thickness specification in available documentation. Both parts utilize tin contact finish material.

Q: Does the color difference between the connectors affect substitution?

A: The TE Connectivity 3-643828-5 features black housing, while the Adam Tech MTD-A-05-E-2 features blue housing. Color is a cosmetic attribute and does not affect electrical performance, mechanical fit, or functional compatibility. Selection based on color preference is application-dependent.

Q: What is the significance of the product status difference?

A: The TE Connectivity 3-643828-5 is classified as obsolete, indicating discontinued production. The Adam Tech MTD-A-05-E-2 is active, meaning it is currently manufactured and available for procurement. This status difference makes the substitute essential for ongoing supply requirements.

Q: Are the RoHS compliance levels equivalent?

A: The TE Connectivity 3-643828-5 is RoHS Compliant, while the Adam Tech MTD-A-05-E-2 is ROHS3 Compliant. ROHS3 represents the current regulatory standard and includes the restrictions of earlier RoHS versions. Both parts meet current environmental compliance requirements.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes. The connectors are mechanically and electrically interchangeable. The identical pitch, position count, termination method, and wire gauge specifications ensure compatibility with existing cable assemblies and PCB layouts designed for the TE Connectivity 3-643828-5.

Q: What packaging options are available for the substitute part?

A: The Adam Tech MTD-A-05-E-2 is available in bulk packaging. The original TE Connectivity part does not specify packaging type in available documentation.
