AFCT-5701ALZ Equivalent & Substitute Parts

Part Overview

The AFCT-5701ALZ is a transceiver module manufactured by Broadcom Limited, designed for Ethernet applications requiring 1.25Gbd data transmission at 1310nm wavelength. This pluggable SFP module operates within a 3.14V to 3.47V supply voltage range and features LC duplex connectors for optical connectivity.

The AFCT-5701ALZ is classified as obsolete, making substitute components necessary for ongoing system maintenance and new deployments. Identifying compatible alternatives ensures continuity of service while maintaining electrical and mechanical compatibility with existing infrastructure.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-5701ALZ are identified based on the following critical parameters that determine functional compatibility:

• Wavelength (1310nm): All substitutes must operate at the same 1310nm wavelength to ensure optical compatibility with existing network infrastructure.
• Connector Type (LC): LC connectors are required for physical and optical alignment with deployed systems.
• Mounting Type (Pluggable, SFP/SFP28): Substitutes must be pluggable modules compatible with SFP or SFP28 form factors.
• Supply Voltage Compatibility: Operating voltage ranges must be compatible with system power delivery specifications.
• RoHS and Regulatory Compliance: All substitutes must maintain equivalent or superior compliance status.

Two substitute parts meet these criteria: AFCT-725SMZ and AFCT-5701ALZ-C.

Parameter Comparison

Engineering Selection Recommendations

AFCT-5701ALZ-C is the primary substitute for direct replacement applications. Manufactured by ProLabs as an Avago AFCT-5701ALZ compatible module, it maintains the same SFP form factor and 1310nm wavelength specification. With active product status and RoHS compliance, this part ensures long-term availability and regulatory alignment for new deployments and system maintenance.

AFCT-725SMZ is suitable for applications requiring higher data rate capacity. Operating at 25Gbps with SFP28 form factor compatibility, this Broadcom part supports future bandwidth requirements while maintaining 1310nm wavelength operation. However, the SFP28 form factor differs from the original SFP specification, requiring verification of host equipment compatibility. This part is classified as Last Time Buy, limiting future procurement options.

Frequently Asked Questions (FAQ)

Q: Can AFCT-725SMZ directly replace AFCT-5701ALZ in existing systems?

A: Direct replacement requires host equipment compatibility with SFP28 form factor. While both modules operate at 1310nm wavelength with LC connectors, the AFCT-725SMZ uses SFP28 form factor versus the original SFP form factor. Verify host equipment specifications before substitution.

Q: What is the primary advantage of AFCT-5701ALZ-C as a substitute?

A: AFCT-5701ALZ-C maintains identical form factor (SFP) and wavelength (1310nm) specifications as the original AFCT-5701ALZ. As an active product with RoHS compliance, it provides direct compatibility and long-term availability for replacement and new installations.

Q: Are there voltage compatibility concerns with substitute parts?

A: AFCT-5701ALZ operates within 3.14V to 3.47V. AFCT-725SMZ operates at 3.3V, which falls within the original voltage range. AFCT-5701ALZ-C voltage specifications are not provided in available documentation. Verify power supply specifications for your specific application.

Q: Why is AFCT-5701ALZ classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Broadcom Limited. AFCT-5701ALZ-C and AFCT-725SMZ provide active alternatives for continued system support and new deployments.

Q: What does Moisture Sensitivity Level (MSL) indicate for these parts?

A: MSL rating specifies storage and handling requirements. AFCT-5701ALZ has MSL 3 (168 hours maximum floor life), while AFCT-725SMZ has MSL 1 (unlimited floor life), indicating superior moisture tolerance and reduced handling constraints.
