AFCT-57F3TMZ-NA2 Equivalent & Substitute Parts

Part Overview

The AFCT-57F3TMZ-NA2 is a Fibre Channel transceiver module manufactured by Broadcom Limited. This SFP+ pluggable transceiver operates at 14.025Gbps with a 1310nm wavelength and supports LC Duplex connectivity. The module is classified as Obsolete and requires identification of equivalent or substitute components for ongoing system deployment and maintenance.

Due to its obsolete product status, direct replacement parts or functionally equivalent alternatives must be evaluated to maintain system compatibility and operational continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-57F3TMZ-NA2 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
• Applications: Fibre Channel or Fibre Channel Links
• Voltage Supply Range: Overlapping or compatible operating voltage
• RoHS Compliance: ROHS3 or equivalent environmental compliance

Substitute Classification:

1. MFR Recommended Substitute (AFCT-57G5MZ): Active product status with higher data rate capability (28.05Gbps), same wavelength (1310nm), compatible voltage range (3.1V ~ 3.5V), and identical form factor (SFP+, LC Duplex). Broadcom Limited manufacturer continuity.

2. Similar Substitute (AFCT-57F3TMZ-NA2-C): Active product status with 16Gbps data rate, 1310nm wavelength, compatible connector (LC), and SFP+ form factor. Manufactured by ATGBICS with RoHS compliance and EAR99 classification.

Parameter Comparison

Engineering Selection Recommendations

AFCT-57G5MZ (MFR Recommended Substitute): This substitute is the manufacturer-recommended replacement. It maintains Broadcom Limited manufacturing continuity, ROHS3 compliance, and identical form factor (SFP+, LC Duplex). The voltage supply range (3.1V ~ 3.5V) overlaps with the original specification (3.135V ~ 3.465V). The higher data rate (28.05Gbps) provides forward compatibility with Fibre Channel Links applications. Active product status ensures ongoing availability and support.

AFCT-57F3TMZ-NA2-C (Similar Substitute): This substitute provides an alternative from ATGBICS with active product status and RoHS compliance. The 16Gbps data rate exceeds the original 14.025Gbps specification. The 1310nm wavelength and SFP+ form factor maintain physical and optical compatibility. The fixed 3.3V supply falls within the original operating range. This option is suitable for applications where General Purpose transceiver classification is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-57G5MZ be used as a direct replacement for the AFCT-57F3TMZ-NA2?

A: Yes. Both modules share identical form factor (SFP+), connector type (LC Duplex), wavelength (1310nm), and voltage supply compatibility. The AFCT-57G5MZ operates at 28.05Gbps, which is higher than the original 14.025Gbps specification. The overlapping voltage ranges (3.1V ~ 3.5V versus 3.135V ~ 3.465V) ensure power supply compatibility.

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

A: The AFCT-57G5MZ is the manufacturer-recommended substitute from Broadcom Limited with identical form factor and connector specifications. The AFCT-57F3TMZ-NA2-C is a similar substitute from ATGBICS with comparable specifications but different manufacturer origin and General Purpose application classification rather than Fibre Channel Links.

Q: Are both substitutes compatible with existing Fibre Channel infrastructure?

A: Both substitutes operate at 1310nm wavelength with SFP+ form factor and LC connector compatibility. The AFCT-57G5MZ is specifically rated for Fibre Channel Links applications. The AFCT-57F3TMZ-NA2-C is classified for General Purpose applications but maintains the same optical and physical interface specifications.

Q: What is the significance of the higher data rates in the substitute parts?

A: The AFCT-57G5MZ (28.05Gbps) and AFCT-57F3TMZ-NA2-C (16Gbps) both exceed the original 14.025Gbps specification. Higher data rate capability provides forward compatibility and operational margin. System compatibility depends on the receiving equipment's ability to operate at these rates or support backward compatibility to lower speeds.

Q: Are there any voltage supply considerations when selecting a substitute?

A: The original AFCT-57F3TMZ-NA2 operates at 3.135V ~ 3.465V. The AFCT-57G5MZ operates at 3.1V ~ 3.5V with overlapping range. The AFCT-57F3TMZ-NA2-C operates at fixed 3.3V, which falls within the original range. Verify that the system power supply can deliver the required voltage for the selected substitute.

Q: What does the obsolete status of the original part mean for procurement?

A: Obsolete status indicates that the AFCT-57F3TMZ-NA2 is no longer manufactured or supported by Broadcom Limited. Substitute parts with Active product status (AFCT-57G5MZ and AFCT-57F3TMZ-NA2-C) ensure ongoing availability, manufacturing support, and compliance with current environmental standards.

Q: How do RoHS compliance levels affect substitute selection?

A: The original part is ROHS3 compliant. The AFCT-57G5MZ maintains ROHS3 compliance. The AFCT-57F3TMZ-NA2-C is RoHS compliant. Both substitutes meet or exceed the environmental compliance requirements of the original part.
