Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-57J5ATPZ is determined by the following critical parameters:

• Data Rate Compatibility: The substitute must support 3Gbps or higher to accommodate the original 3.072Gbps specification
• Wavelength: 1310nm single-mode operation is required
• Voltage Supply: 3.3V operation is mandatory
• Connector Type: LC Duplex connectors are required for physical compatibility
• Mounting Type: SFP or SFP+ pluggable form factor is acceptable
• Application Domain: General-purpose and networking applications are compatible

The AFCT-57J5ATPZ-C, manufactured by ATGBICS, meets these substitution criteria as a Broadcom-compatible alternative. This part maintains electrical and mechanical compatibility while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The AFCT-57J5ATPZ-C is qualified as a direct substitute based on the following engineering criteria:

• Electrical Compatibility: Both parts operate at 3.3V with matching wavelength (1310nm) and connector specifications (LC Duplex)
• Data Rate Margin: The substitute's 3Gbps rating accommodates the original 3.072Gbps requirement within standard optical transceiver performance tolerances
• Product Status: The substitute maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Form Factor: SFP+ compatibility is backward-compatible with SFP-based systems, providing mechanical interchangeability
• Compliance: The substitute carries EAR99 classification, maintaining regulatory alignment with the original part's ECCN 5A991B5A designation

Frequently Asked Questions (FAQ)

Q: Can the AFCT-57J5ATPZ-C operate in systems designed for the AFCT-57J5ATPZ?

A: Yes. Both parts share identical electrical specifications (3.3V supply, 1310nm wavelength, LC Duplex connectors) and operate within compatible data rate ranges. The SFP+ form factor is mechanically compatible with SFP slots.

Q: What is the difference between SFP and SFP+ form factors?

A: SFP+ is a higher-density variant of the SFP standard. SFP+ modules are backward-compatible with SFP receptacles, allowing direct physical installation without adapter requirements.

Q: Why is the original AFCT-57J5ATPZ classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The AFCT-57J5ATPZ-C provides an active alternative with equivalent functionality and improved supply availability.

Q: Are there any compliance or certification differences between these parts?

A: The original part carries ECCN 5A991B5A classification, while the substitute is classified as EAR99. Both designations are standard for optical transceiver modules and do not restrict substitution in general-purpose applications.

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

A: The AFCT-57J5ATPZ-C is supplied in Tray packaging, suitable for bulk procurement and automated assembly processes.
