Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HFCT-5911ATLZ are identified based on the following critical parameters that determine functional compatibility:

• Connector Type: LC Duplex (required for physical interface compatibility)
• Mounting Type: Through Hole (required for PCB integration)
• Wavelength: 1310nm (primary operating wavelength for this application class)
• Data Rate: 1.25Gbps minimum (supports the required bandwidth)
• Voltage Supply Range: Compatible with 3.1V ~ 4.6V operation
• Applications: Ethernet or Networking, General Purpose

The substitute part HFCT-5911ATLZ-C, manufactured by ATGBICS as a Broadcom-compatible alternative, meets these core substitution criteria while maintaining functional equivalence for Ethernet transceiver applications.

Engineering Selection Recommendations

The HFCT-5911ATLZ-C serves as the primary substitute for the obsolete HFCT-5911ATLZ. Selection of this substitute is supported by the following factors:

• Product Status: The substitute part maintains active status, ensuring ongoing availability and supply chain continuity.
• Compliance: Both the main part and substitute maintain REACH Unaffected status, confirming regulatory alignment.
• Physical Compatibility: Identical LC Duplex connector type and through-hole mounting ensure direct mechanical integration without redesign.
• Electrical Compatibility: The substitute operates at 3.3V, which falls within the acceptable range for systems designed for the 3.1V ~ 4.6V specification of the main part.
• Functional Scope: The substitute supports both 1310nm and 850nm wavelengths, providing operational flexibility for Ethernet and general networking applications.

Frequently Asked Questions (FAQ)

Q: Can the HFCT-5911ATLZ-C directly replace the HFCT-5911ATLZ in existing designs?

A: Yes. Both parts share identical connector type (LC Duplex) and mounting type (through hole), enabling direct mechanical and electrical substitution. The substitute's 3.3V supply voltage is compatible with the main part's 3.1V ~ 4.6V specification range.

Q: What is the difference in data rate between the main part and substitute?

A: The main part operates at 1.25Gbps, while the substitute operates at 1000Mbps. The substitute's data rate is lower but remains suitable for Ethernet applications within this performance class.

Q: Does the substitute support the same wavelength as the main part?

A: The substitute supports both 1310nm and 850nm wavelengths, providing dual-wavelength capability. The 1310nm wavelength matches the main part's specification, ensuring compatibility for existing optical infrastructure.

Q: What is the packaging difference between these parts?

A: The main part packaging is listed as standard, while the substitute is supplied in Tray packaging. This difference affects handling and storage but does not impact functional performance or electrical characteristics.

Q: Are there compliance or regulatory differences between the parts?

A: Both parts maintain REACH Unaffected status. The substitute is RoHS Compliant, providing additional environmental compliance assurance for applications requiring this certification.
