Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 74990111215 directly replace the TE Connectivity 1-6605316-1?

A: The Würth Elektronik 74990111215 provides full mechanical and electrical compatibility with identical 6-core jack configuration, AutoMDIX support, and shielded EMI finger construction. The primary consideration is the narrower operating temperature range of 0°C ~ 70°C compared to the original -40°C ~ 85°C specification. For applications within the 0°C ~ 70°C range, this part is a direct substitute.

Q: What is the difference between 6-core and 4-core RJ45 jack configurations?

A: The 6-core configuration provides additional contact points for Power over Ethernet (PoE) support and enhanced signal integrity. The 4-core configuration is suitable for standard 10/100 Base-T applications without PoE. Both configurations support AutoMDIX functionality when specified. Selection depends on application requirements.

Q: Is the Bel Fuse Inc. SI-60062-F suitable for my application?

A: The Bel Fuse Inc. SI-60062-F is suitable for applications requiring 10/100 Base-T AutoMDIX functionality without Power over Ethernet support. The 4-core configuration and height above board of 13.84mm match the original specification. Operating temperature range is not specified in available documentation. Verify application requirements before selection.

Q: What is the significance of the operating temperature range difference?

A: The TE Connectivity 1-6605316-1 operates from -40°C ~ 85°C, supporting extended temperature applications including industrial and automotive environments. Würth Elektronik 74990111215 and 7499211123 operate from 0°C ~ 70°C, suitable for standard commercial and office environments. Selection must align with application temperature requirements.

Q: Can I use a part with 5-core configuration instead of 6-core?

A: The Bel Fuse Inc. SI-60015-F and SI-60076-F provide 5-core configurations for 10/100 Base-T applications. These parts lack AutoMDIX functionality. Use only if your application does not require AutoMDIX support and the 5-core configuration meets electrical requirements.

Q: What is the importance of the "Board Guide" feature?

A: The Board Guide feature provides mechanical alignment and stability during PCB assembly and operation. All recommended substitute parts include this feature, ensuring consistent mechanical performance and reliability.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed are ROHS3 compliant. The original TE Connectivity 1-6605316-1 has RoHS Status listed as "Not applicable" due to its obsolete status. ROHS3 compliance is standard for all active alternatives.

Q: What packaging options are available for substitute parts?

A: Würth Elektronik parts are supplied in Tube packaging. Bel Fuse Inc. MagJack® ST SI-60000 series parts are supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: How do I determine which substitute part is best for my design?

A: Selection criteria include: (1) Operating temperature range requirements, (2) Power over Ethernet (PoE) support necessity, (3) Core count requirements (4-core, 5-core, or 6-core), (4) AutoMDIX functionality requirement, (5) Height above board constraints, (6) Packaging and inventory availability. Cross-reference your application specifications against the Parameter Comparison table to identify the optimal substitute.
