AFCT-57F5TMZ Equivalent & Substitute Parts

Part Overview

The AFCT-57F5TMZ is a transceiver module manufactured by Broadcom Limited, designed for Fibre Channel Links applications. This module operates at 9.138Gbps with a 1310nm wavelength and features LC Duplex connectors in a pluggable QSFP+ form factor. The product is discontinued at DiGi Electronics, making equivalent and substitute parts essential for system maintenance and component sourcing. Substitute parts must maintain compatibility across critical electrical and mechanical parameters including data rate, wavelength, connector type, and voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-57F5TMZ is determined by the following critical parameters:

Primary Compatibility Criteria:

• Wavelength: 1310nm (must match)
• Connector Type: LC (must match)
• Voltage Supply Range: Compatible with 3.135V ~ 3.465V or 3.3V nominal
• RoHS Compliance: ROHS3 Compliant status required

Secondary Considerations:

• Data Rate: Substitute parts may operate at equal or higher data rates
• Mounting Type: Form factor differences (QSFP+ vs SFP+) affect physical installation but do not preclude electrical substitution in compatible systems
• Product Status: Active status preferred for long-term availability

The AFCT-57F5TMZ-C qualifies as a substitute based on matching wavelength (1310nm), connector type (LC), voltage compatibility (3.3V within the supply range), and RoHS compliance. The higher data rate (16Gbps vs 9.138Gbps) and different form factor (SFP+ vs QSFP+) represent functional enhancements and physical differences that require system-level verification.

Parameter Comparison

Engineering Selection Recommendations

AFCT-57F5TMZ-C Substitution Basis:

The AFCT-57F5TMZ-C is listed as an official substitute and maintains electrical compatibility through matching wavelength (1310nm) and connector type (LC). The supply voltage of 3.3V falls within the acceptable range of the original part (3.135V ~ 3.465V). The higher data rate capability (16Gbps) provides operational margin above the original specification (9.138Gbps).

Form Factor Consideration:

The transition from QSFP+ to SFP+ form factor requires physical slot compatibility verification in the target system. While electrically compatible, mechanical installation differences necessitate confirmation that the receiving equipment supports SFP+ modules.

Compliance Status:

The substitute part maintains active product status, ensuring continued availability and supply chain reliability compared to the discontinued original part. RoHS compliance information for the substitute should be confirmed with the manufacturer prior to procurement for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can AFCT-57F5TMZ-C directly replace AFCT-57F5TMZ in all applications?

A: Electrical compatibility is established through matching wavelength, connector type, and voltage specifications. Physical compatibility requires verification that the target system supports SFP+ form factor modules, as the original part uses QSFP+ form factor.

Q: What is the significance of the higher data rate in the substitute part?

A: The AFCT-57F5TMZ-C operates at 16Gbps compared to the original 9.138Gbps. This higher capability does not prevent substitution; however, the system must be capable of operating at the original data rate or the substitute's capabilities must align with system requirements.

Q: Are there voltage compatibility concerns?

A: The substitute part operates at 3.3V nominal, which falls within the original part's supply range of 3.135V ~ 3.465V. Voltage compatibility is established.

Q: Why is the original part discontinued?

A: Product discontinuation at DiGi Electronics indicates end-of-life status for the original manufacturer's part. The substitute part maintains active status, providing continued availability for system maintenance and new deployments.

Q: What packaging differences exist between the parts?

A: The original part is specified with standard packaging, while the substitute is supplied in Tray packaging. Packaging format does not affect electrical or mechanical performance.

Q: Should RoHS compliance be verified for the substitute?

A: Yes. The original part is ROHS3 Compliant. RoHS status for the substitute should be confirmed with ATGBICS prior to procurement, particularly for applications subject to regulatory compliance requirements.
