AFCT-5715PZ-FD1 Equivalent & Substitute Parts

Part Overview

The AFCT-5715PZ-FD1 is a transceiver module manufactured by Broadcom Limited, designed for Ethernet applications operating at 1.25Gbd data rate with 1313nm wavelength transmission. The module features LC Duplex connectors and operates within a supply voltage range of 3.14V to 3.47V in a pluggable SFP form factor.

This part is classified as Obsolete, making identification of equivalent and substitute components essential for system maintenance, redesign, and procurement planning. The availability of 729 pieces in current inventory does not guarantee long-term supply continuity. Substitute parts must maintain functional compatibility across critical electrical and mechanical parameters while accounting for differences in form factor, data rate capability, and voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the AFCT-5715PZ-FD1 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector Type: LC Duplex (physical interface must match)
• Mounting Type: Pluggable form factor (SFP or SFP28)
• Wavelength: 1310nm–1313nm range (optical transmission window)
• Data Rate: 1.25Gbps minimum (backward compatibility with Ethernet GE applications)
• Voltage Supply: 3.3V nominal (standard for modern transceiver modules)
• RoHS Compliance: ROHS3 or equivalent (regulatory requirement)

Substitution Constraints:

• Form factor differences (SFP vs. SFP28) affect slot compatibility and require hardware verification
• Data rate upgrades (e.g., 25Gbps) provide forward compatibility but do not reduce to lower rates
• Voltage tolerance windows must overlap or be verified against host equipment specifications
• Wavelength variations within the 1310nm band maintain optical compatibility for long-reach Ethernet applications

The two substitute parts identified below meet these criteria with documented trade-offs in form factor and data rate capability.

Engineering Selection Recommendations

AFCT-5715PZ-FD1-C (Recommended Primary Substitute)

The AFCT-5715PZ-FD1-C manufactured by ATGBICS is the optimal substitute for direct replacement applications. This part maintains identical data rate (1.25Gbps), connector type (LC Duplex), and mounting form factor (Pluggable, SFP) as the original AFCT-5715PZ-FD1. The wavelength specification of 1310nm is compatible with the 1313nm original within the long-reach Ethernet transmission window. Supply voltage is standardized at 3.3V, which falls within acceptable tolerance for host equipment designed for the original part. The part holds Active product status with 9415 units in inventory, ensuring supply continuity. RoHS compliance is maintained, and ECCN classification as EAR99 provides favorable regulatory handling. This substitute requires no hardware modifications and supports direct slot-level replacement.

AFCT-725SMZ (Secondary Substitute for Data Rate Upgrade Scenarios)

The AFCT-725SMZ from Broadcom Limited is applicable only in systems where higher data rate capability (25Gbps) is required and the host equipment supports SFP28 form factor slots. This part is not a direct replacement due to form factor incompatibility (SFP28 vs. SFP) and requires hardware slot verification before deployment. The wavelength (1310nm) and voltage specification (3.3V) are compatible with the original application. Product status is Last Time Buy, indicating limited future availability. This substitute is suitable for forward-migration scenarios where system upgrades to 25GE capability are planned and SFP28 slot availability is confirmed.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-5715PZ-FD1-C be used as a direct plug-in replacement for the AFCT-5715PZ-FD1?

A: Yes. The AFCT-5715PZ-FD1-C maintains identical form factor (Pluggable, SFP), connector type (LC Duplex), and data rate (1.25Gbps). No hardware modifications are required. The wavelength difference (1310nm vs. 1313nm) operates within the same optical transmission band for long-reach Ethernet applications.

Q: What is the primary difference between the two substitute parts?

A: The AFCT-5715PZ-FD1-C is a direct form-factor match (SFP) with equivalent data rate (1.25Gbps), while the AFCT-725SMZ is a higher-capacity part (25Gbps) in a different form factor (SFP28). The AFCT-725SMZ requires host equipment with SFP28 slot support and is not a direct replacement.

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

A: The original AFCT-5715PZ-FD1 operates at 3.14V–3.47V. Both substitute parts operate at 3.3V nominal. This voltage is within the tolerance window of the original specification and is compatible with standard Ethernet transceiver host equipment. No power supply modifications are required.

Q: Does wavelength difference affect optical compatibility?

A: The original part operates at 1313nm, while both substitutes operate at 1310nm. Both wavelengths fall within the 1310nm long-reach Ethernet transmission window and are optically compatible for the same application class. Fiber optic infrastructure designed for 1310nm long-reach transmission supports both wavelengths.

Q: What is the significance of product status (Obsolete, Last Time Buy, Active)?

A: Obsolete status indicates the AFCT-5715PZ-FD1 is no longer manufactured and current inventory (729 units) represents final available stock. Last Time Buy status for the AFCT-725SMZ indicates limited future production. Active status for the AFCT-5715PZ-FD1-C indicates ongoing manufacture and supply availability, making it the most reliable long-term substitute.

Q: Can the AFCT-725SMZ be used in an SFP slot?

A: No. The AFCT-725SMZ is an SFP28 form factor module and is physically incompatible with standard SFP slots. Host equipment must have dedicated SFP28 slots to accommodate this part. Attempting to install an SFP28 module in an SFP slot will result in physical interference and equipment damage.

Q: Are all substitute parts RoHS compliant?

A: Yes. The AFCT-5715PZ-FD1-C is RoHS Compliant, and the AFCT-725SMZ is ROHS3 Compliant. Both meet current environmental and regulatory requirements for electronic component manufacturing and deployment.
