Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-5750APZ are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Mounting Type: Pluggable, SFP (form factor compatibility)
• Connector Type: LC Duplex (physical interface compatibility)
• Wavelength: 1300nm (optical transmission compatibility)
• Voltage Supply Range: Compatibility with 3.1V ~ 4.6V supply rails

Secondary Considerations:

• Data Rate: The original part operates at 622Mbps; substitute parts may operate at different data rates depending on application requirements
• RoHS and REACH Compliance: All identified substitutes maintain ROHS3 compliance and REACH unaffected status
• Product Status: Active substitutes are preferred for new deployments; obsolete alternatives may be used for legacy system maintenance

The substitute parts listed below meet the core physical and electrical compatibility requirements for direct replacement in SFP-based optical systems.

Engineering Selection Recommendations

HFBR-57E0APZ (Broadcom Limited)

This substitute maintains Broadcom Limited manufacturing, ROHS3 compliance, and identical wavelength (1300nm) and connector type (LC Duplex) specifications. The part is currently active in production. The supply voltage of 3.3V is within the acceptable range of the original part (3.1V ~ 4.6V). The data rate of 155MBd is lower than the original 622Mbps specification; this part is suitable for applications where lower bandwidth requirements exist or where backward compatibility with legacy Ethernet systems is required.

AFCT-5750APZ-C (ATGBICS)

This substitute is manufactured by ATGBICS and is currently active in production. It maintains SFP pluggable form factor and LC connector compatibility. The wavelength specification of 1310nm is within the 1300nm band and is compatible with standard 1300nm optical systems. The data rate of 1.25Gbps exceeds the original specification, providing higher bandwidth capability. The supply voltage of 3.3V is compatible with the original part's voltage range. This part is suitable for applications requiring higher data rates or where future bandwidth expansion is anticipated.

Frequently Asked Questions (FAQ)

Q: Can HFBR-57E0APZ directly replace AFCT-5750APZ in all applications?

A: HFBR-57E0APZ shares the same form factor (SFP), connector type (LC Duplex), and wavelength (1300nm) as the original part. However, the data rate is 155MBd compared to the original 622Mbps. Direct replacement is possible only in applications where the lower data rate is acceptable or where the system is designed to operate at 155MBd speeds.

Q: What is the difference between 1300nm and 1310nm wavelengths?

A: Both wavelengths operate within the same optical transmission window and are compatible with standard 1300nm optical infrastructure. The 1310nm specification of AFCT-5750APZ-C is within the acceptable tolerance for 1300nm systems.

Q: Are all substitute parts RoHS compliant?

A: HFBR-57E0APZ and the main part AFCT-5750APZ are both ROHS3 compliant. AFCT-5750APZ-C does not specify RoHS status in the provided data; verification with the manufacturer is required if RoHS compliance is a system requirement.

Q: What does MSL (Moisture Sensitivity Level) mean for component selection?

A: MSL indicates the maximum time a component can be exposed to moisture before soldering. The original part has MSL 3 (168 hours), while HFBR-57E0APZ has MSL 1 (unlimited). Lower MSL values indicate less sensitivity to moisture and longer shelf life. AFCT-5750APZ-C lists MSL as not applicable, indicating it may not require moisture-controlled storage.

Q: Can AFCT-5750APZ-C replace AFCT-5750APZ in legacy systems?

A: AFCT-5750APZ-C is compatible in terms of form factor (SFP) and connector type (LC). However, the higher data rate (1.25Gbps) and different manufacturer (ATGBICS vs. Broadcom Limited) require verification that the host system can support these specifications. Compatibility testing is recommended before deployment in critical legacy systems.
