AFCT-57F5ATMZ Equivalent & Substitute Parts

Part Overview

The AFCT-57F5ATMZ is a Broadcom Limited SFP+ transceiver module designed for Fibre Channel links operating at 9.138Gbps with 1310nm wavelength and LC Duplex connectivity. This module is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing system maintenance and component procurement. The module operates within a 3.135V to 3.465V supply voltage range and is classified as RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-57F5ATMZ is determined by the following critical parameters:

• Wavelength: 1310nm (must match)
• Connector Type: LC Duplex or LC (compatible)
• Mounting Type: Pluggable, SFP+ (must match)
• Data Rate Compatibility: Minimum 9.138Gbps or higher
• Voltage Supply Range: Must accommodate 3.135V ~ 3.465V operation or be compatible with 3.3V nominal

The AFCT-57F5ATMZ-C qualifies as a substitute based on matching wavelength (1310nm), connector compatibility (LC), SFP+ form factor, and data rate capability (16Gbps exceeds 9.138Gbps requirement). Voltage supply at 3.3V falls within the acceptable operating range.

Engineering Selection Recommendations

The AFCT-57F5ATMZ-C serves as an active substitute for the discontinued AFCT-57F5ATMZ. Selection should be based on the following factors:

Product Availability: The AFCT-57F5ATMZ-C is currently active with 9505 units in stock, whereas the original part is discontinued.

Compliance: The main part carries ROHS3 compliance certification. The substitute part's RoHS status is not specified in available documentation and should be confirmed during procurement if RoHS compliance is a system requirement.

Electrical Compatibility: The substitute operates at 3.3V nominal supply, which falls within the original part's 3.135V to 3.465V operating range, ensuring electrical compatibility.

Performance Headroom: The substitute's 16Gbps data rate exceeds the original 9.138Gbps specification, providing operational margin without introducing incompatibility.

Form Factor and Connectivity: Both parts use identical SFP+ pluggable form factor and LC-type connectors, ensuring mechanical and electrical interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-57F5ATMZ-C directly replace the AFCT-57F5ATMZ in existing systems?

A: Yes, provided the system supports LC connector interfaces and SFP+ form factor. The substitute's higher data rate (16Gbps vs. 9.138Gbps) and compatible voltage supply (3.3V within the 3.135V–3.465V range) ensure functional compatibility.

Q: What is the significance of the wavelength matching at 1310nm?

A: Wavelength is a critical optical parameter. Both parts operate at 1310nm, ensuring they transmit and receive on the same optical frequency and are compatible with existing fiber infrastructure designed for this wavelength.

Q: Does the higher data rate of the substitute part affect compatibility?

A: No. Higher data rate capability does not create incompatibility. The substitute will operate at the system's required speed (9.138Gbps or lower) without issues.

Q: What is the difference between LC Duplex and LC connectors?

A: LC Duplex refers to a dual-fiber connector configuration, while LC refers to the connector type itself. Both parts use LC-type connectors compatible with standard fiber optic infrastructure.

Q: Should RoHS compliance status be verified before substitution?

A: If RoHS3 compliance is a mandatory system requirement, the substitute part's RoHS status should be confirmed with the manufacturer or distributor before procurement, as this information is not provided in standard documentation.

Q: What is the packaging difference between the main part and substitute?

A: The main part packaging is not specified. The substitute is supplied in Tray packaging, which is standard for SFP+ modules and does not affect functional compatibility.
