Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-57F3TMZ-EL5 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Mounting Type: Pluggable, SFP+ form factor
• Connector Type: LC (Duplex or standard)
• Wavelength: 1310nm
• Voltage Supply Range: Overlapping or compatible operating voltage
• Applications: Fibre Channel or General Purpose transceiver functionality

Substitution Logic:

The AFCT-57G5MZ (Broadcom Limited) qualifies as a manufacturer-recommended substitute. While it operates at a higher data rate (28.05Gbps versus 14.025Gbps), it maintains the same wavelength (1310nm), connector type (LC Duplex), mounting type (Pluggable, SFP+), and compatible voltage supply range (3.1V ~ 3.5V overlaps with 3.135V ~ 3.465V). The AFCT-57G5MZ is Active status and ROHS3 compliant.

The AFCT-57F3TMZ-EL5-C (ATGBICS) qualifies as a similar substitute. It operates at 16Gbps with 1310nm wavelength, LC connector, and Pluggable SFP+ mounting. The voltage supply is fixed at 3.3V, which falls within the original part's operating range. This part is Active status and RoHS compliant.

Engineering Selection Recommendations

AFCT-57G5MZ Selection:

The AFCT-57G5MZ is the manufacturer-recommended substitute from Broadcom Limited. This part maintains Active product status, ensuring ongoing availability and support. It is ROHS3 compliant, matching the environmental compliance of the original part. The voltage supply range (3.1V ~ 3.5V) is compatible with the original specification (3.135V ~ 3.465V). The higher data rate (28.05Gbps) provides enhanced performance capability while maintaining backward compatibility with the same physical form factor (Pluggable, SFP+), wavelength (1310nm), and connector type (LC Duplex). This part is suitable for direct replacement in Fibre Channel Link applications.

AFCT-57F3TMZ-EL5-C Selection:

The AFCT-57F3TMZ-EL5-C is an alternative substitute from ATGBICS with Active product status. This part operates at 16Gbps with a fixed 3.3V supply voltage, which is within the original part's operating range. It maintains the same wavelength (1310nm), mounting type (Pluggable, SFP+), and connector type (LC). RoHS compliance is confirmed. This part is applicable for General Purpose transceiver applications and represents an alternative source for SFP+ 1310nm modules.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-57G5MZ directly replace the AFCT-57F3TMZ-EL5?

A: Yes. Both parts share the same physical form factor (Pluggable, SFP+), connector type (LC Duplex), wavelength (1310nm), and compatible voltage supply ranges. The AFCT-57G5MZ operates at a higher data rate (28.05Gbps) but is backward compatible with systems designed for the original 14.025Gbps specification.

Q: What is the difference between the AFCT-57G5MZ and AFCT-57F3TMZ-EL5-C?

A: The AFCT-57G5MZ is manufactured by Broadcom Limited (original manufacturer) and operates at 28.05Gbps with LC Duplex connector. The AFCT-57F3TMZ-EL5-C is manufactured by ATGBICS and operates at 16Gbps with LC connector. Both maintain 1310nm wavelength and Pluggable SFP+ form factor. The AFCT-57G5MZ is the manufacturer-recommended option.

Q: Are voltage supply ranges compatible between the main part and substitutes?

A: Yes. The original part operates at 3.135V ~ 3.465V. The AFCT-57G5MZ operates at 3.1V ~ 3.5V, providing full overlap. The AFCT-57F3TMZ-EL5-C operates at a fixed 3.3V, which falls within the original operating range.

Q: What is the significance of the Pluggable, SFP+ form factor?

A: The Pluggable, SFP+ form factor ensures physical and electrical compatibility with standard SFP+ transceiver slots. All substitute parts maintain this form factor, enabling direct installation without mechanical modification.

Q: Why is the original part classified as Obsolete?

A: The AFCT-57F3TMZ-EL5 is no longer in active production. The substitute parts listed (AFCT-57G5MZ and AFCT-57F3TMZ-EL5-C) are Active status products that provide equivalent or enhanced functionality for continued system support.

Q: Does wavelength compatibility affect substitution?

A: Yes. All listed substitute parts operate at 1310nm, matching the original part's wavelength specification. Wavelength is a critical parameter for optical transceiver compatibility and cannot be altered during substitution.

Q: What is the role of RoHS compliance in part selection?

A: Both the original part and recommended substitutes are RoHS compliant, ensuring environmental and regulatory compliance. The AFCT-57G5MZ is ROHS3 compliant, matching the original specification. The AFCT-57F3TMZ-EL5-C is RoHS compliant, meeting current environmental standards.
