Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-57F3TMZ-I6 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Wavelength: 1310nm
• Connector Type: LC Duplex or LC
• Mounting Type: Pluggable, SFP+
• Supply Voltage Range: Overlapping or compatible with 3.135V ~ 3.465V
• Application Category: Fibre Channel or General Purpose

Substitute Classification:

1. MFR Recommended Substitute (AFCT-57G5MZ): Broadcom Limited manufacturer recommendation. Maintains 1310nm wavelength, LC Duplex connector, SFP+ form factor, and Fibre Channel application compatibility. Operates at 28.05Gbps with supply voltage 3.1V ~ 3.5V, providing voltage range overlap with the original part.

2. Similar Substitute (AFCT-57F3TMZ-I6-C): ATGBICS equivalent. Maintains 1310nm wavelength, LC connector, SFP+ form factor, and compatible supply voltage of 3.3V. Operates at 16Gbps for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

AFCT-57G5MZ (MFR Recommended Substitute): This substitute is the manufacturer-recommended replacement for the obsolete AFCT-57F3TMZ-I6. Both parts are manufactured by Broadcom Limited and maintain ROHS3 compliance. The AFCT-57G5MZ is currently in active product status with 774 units in stock. The supply voltage range (3.1V ~ 3.5V) overlaps with the original specification (3.135V ~ 3.465V), ensuring power supply compatibility. The identical wavelength (1310nm), connector type (LC Duplex), and mounting type (Pluggable, SFP+) provide direct mechanical and optical compatibility. The higher data rate (28.05Gbps versus 14.025Gbps) represents a performance upgrade suitable for Fibre Channel Links applications.

AFCT-57F3TMZ-I6-C (Similar Substitute): This substitute is manufactured by ATGBICS and is currently in active product status with 9524 units in stock. It maintains the 1310nm wavelength, SFP+ form factor, and LC connector configuration. The supply voltage specification (3.3V) falls within the acceptable range of the original part. This substitute operates at 16Gbps, positioned between the original 14.025Gbps and the MFR recommended 28.05Gbps. RoHS compliance is confirmed. This option is suitable for general-purpose applications where Fibre Channel compatibility is required.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-57G5MZ directly replace the AFCT-57F3TMZ-I6 in existing Fibre Channel systems?

A: Yes. Both parts share identical wavelength (1310nm), connector type (LC Duplex), and mounting type (Pluggable, SFP+). The supply voltage ranges overlap (3.1V ~ 3.5V versus 3.135V ~ 3.465V). Both are ROHS3 compliant. The AFCT-57G5MZ is the manufacturer-recommended substitute and is currently in active production status.

Q: What is the difference between the MFR Recommended and Similar substitutes?

A: The AFCT-57G5MZ is the Broadcom Limited manufacturer-recommended replacement, maintaining the same manufacturer and Fibre Channel application focus. The AFCT-57F3TMZ-I6-C is manufactured by ATGBICS and is classified as a similar substitute with general-purpose application capability. Both maintain 1310nm wavelength and SFP+ form factor compatibility.

Q: Are there voltage compatibility concerns when substituting these parts?

A: No. The supply voltage ranges of all three parts overlap sufficiently. The original AFCT-57F3TMZ-I6 operates at 3.135V ~ 3.465V, the AFCT-57G5MZ at 3.1V ~ 3.5V, and the AFCT-57F3TMZ-I6-C at 3.3V. All three specifications are compatible with standard 3.3V power supply systems.

Q: Does the higher data rate of the AFCT-57G5MZ (28.05Gbps) affect compatibility?

A: No. Higher data rate capability does not prevent operation at lower speeds. The AFCT-57G5MZ supports 28.05Gbps but is backward compatible with systems designed for 14.025Gbps operation. The identical optical and mechanical specifications ensure seamless integration.

Q: What is the connector difference between the AFCT-57G5MZ and AFCT-57F3TMZ-I6-C?

A: The AFCT-57G5MZ features an LC Duplex connector, identical to the original AFCT-57F3TMZ-I6. The AFCT-57F3TMZ-I6-C features an LC connector. Both connector types are compatible with standard SFP+ transceiver slots and 1310nm optical systems.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original AFCT-57F3TMZ-I6 is ROHS3 compliant. The AFCT-57G5MZ is ROHS3 compliant. The AFCT-57F3TMZ-I6-C is RoHS compliant. All three parts meet environmental compliance requirements.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute parts?

A: The AFCT-57G5MZ has MSL 1 (Unlimited), identical to the original part. The AFCT-57F3TMZ-I6-C has MSL listed as Not Applicable. Both substitutes meet or exceed the moisture handling requirements of the original component.
