Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-57V6AUSZ are identified based on the following critical parameters that determine functional compatibility:

• Data Rate: 1.25Gbd/1.25Gbps
• Wavelength: 1550nm
• Voltage - Supply: 3.3V
• Connector Type: LC (Duplex or standard)
• Mounting Type: Pluggable, SFP
• Applications: Ethernet or General Purpose

The substitute part AFCT-57V6AUSZ-C matches all critical electrical and mechanical parameters required for direct substitution in SFP-based transceiver slots. The transition from Obsolete to Active product status provides improved availability and supply chain continuity.

Engineering Selection Recommendations

The AFCT-57V6AUSZ-C is the manufacturer-recommended substitute for the obsolete AFCT-57V6AUSZ. Selection of this substitute part is based on:

• Matching electrical specifications: identical data rate (1.25Gbd/Gbps), wavelength (1550nm), and supply voltage (3.3V)
• Compatible mechanical form factor: both are pluggable SFP modules with LC connector configuration
• Active product status: AFCT-57V6AUSZ-C is currently in production, ensuring supply availability and long-term support
• Compliance alignment: AFCT-57V6AUSZ-C carries EAR99 classification, providing regulatory clarity for procurement and deployment

Frequently Asked Questions (FAQ)

Q: Can AFCT-57V6AUSZ-C be used as a direct replacement for AFCT-57V6AUSZ?

A: Yes. Both modules operate at 1.25Gbd data rate with 1550nm wavelength and 3.3V supply voltage. The SFP form factor and LC connector configuration are identical, enabling direct insertion into compatible transceiver slots.

Q: What is the difference between LC Duplex and LC connector types listed in the specifications?

A: LC Duplex refers to a dual-fiber connector configuration with two LC connectors in a single housing. The AFCT-57V6AUSZ-C specification lists LC, which is compatible with duplex applications. Both support bidirectional Ethernet transmission at the specified data rate.

Q: Why is the AFCT-57V6AUSZ marked as Obsolete?

A: Obsolete status indicates the part is no longer manufactured by Broadcom Limited. The AFCT-57V6AUSZ-C provides functional equivalence with active production status, ensuring continued availability for system maintenance and expansion.

Q: Are there packaging differences between the main part and substitute?

A: The AFCT-57V6AUSZ-C is supplied in Tray packaging, while the main part packaging is not specified. Tray packaging is standard for SFP transceiver modules and does not affect electrical or mechanical compatibility.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: The main part specifies MSL 3 (168 Hours), indicating moisture sensitivity during storage and handling. The substitute part lists MSL as Not Applicable, indicating either lower sensitivity or different handling requirements. Verify storage and handling procedures according to the substitute manufacturer's documentation.
