Frequently Asked Questions (FAQ)

Q: What makes the Hirose TM11R-5N2-88(50) a suitable substitute for the TE Connectivity 6605838-1?

A: The Hirose substitute matches all critical parameters: RJ45 jack connector type, 1 port configuration, through-hole mounting, 90° right-angle orientation, solder termination, shielded construction, phosphor bronze contacts with 50.0µin gold plating, and absence of LED indicators. These parameters define functional equivalence for modular Ethernet connector applications.

Q: Are there any differences in housing material between the main part and substitute?

A: Yes. The TE Connectivity 6605838-1 uses Polyethylene Terephthalate (PET) and Polyester housing, while the Hirose TM11R-5N2-88(50) uses Polybutylene Terephthalate (PBT). Both materials are thermoplastic polyesters suitable for modular connector applications. PBT offers enhanced mechanical properties and thermal stability.

Q: Does the substitute support the same Ethernet applications as the original part?

A: The substitute supports Cat5 Ethernet applications. The original part specification indicates 10/100 Base-T compatibility with AutoMDIX support. Cat5 cabling and connectors are rated for 100 Mbps Fast Ethernet applications, providing functional compatibility for the specified use case.

Q: What is the significance of the EMI finger feature on the substitute?

A: The EMI finger shielding on the Hirose substitute provides enhanced electromagnetic interference suppression through additional contact points with the mating connector. This feature maintains or exceeds the shielding performance of the original part while providing additional noise rejection capability.

Q: Is the substitute suitable for PCB assembly processes?

A: Yes. The Hirose TM11R-5N2-88(50) is designed for through-hole PCB assembly with solder termination, identical to the original part. The substitute is supplied in Tray packaging, compatible with standard component handling and automated assembly equipment.

Q: What is the operating temperature difference between the parts?

A: The original part operates from 0°C to 70°C, while the substitute operates from -25°C to 80°C. The substitute provides a 25°C lower temperature minimum and 10°C higher temperature maximum, extending the usable operating range for applications requiring enhanced thermal performance.

Q: Are both parts RoHS compliant?

A: The TE Connectivity 6605838-1 has RoHS status listed as "Not applicable." The Hirose TM11R-5N2-88(50) is RoHS Compliant, meeting current environmental and regulatory requirements for electronic component manufacturing.

Q: Can the substitute be used as a direct replacement in existing designs?

A: The substitute maintains identical electrical and mechanical interface specifications, including connector type, pin configuration, mounting footprint, and termination method. Direct PCB layout compatibility is supported for designs originally specified for the TE Connectivity 6605838-1.
