AFCT-5710ALZ Equivalent & Substitute Parts

Part Overview

The AFCT-5710ALZ is a transceiver module manufactured by Broadcom Limited, designed for Ethernet applications requiring 1.25Gbd data transmission at 1310nm wavelength. The module features LC Duplex connectors and operates within a 3.14V to 3.47V supply voltage range in a pluggable SFP form factor.

The product status is listed as Obsolete, making identification of functionally equivalent alternatives essential for system maintenance, legacy equipment support, and procurement planning. Substitute parts must maintain compatibility across critical electrical and mechanical parameters while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-5710ALZ are identified based on the following critical parameters that determine functional equivalence:

• Wavelength: 1310nm (primary optical characteristic)
• Connector Type: LC (physical interface requirement)
• Mounting Type: Pluggable, SFP or SFP28 (form factor compatibility)
• RoHS Compliance: ROHS3 or equivalent (regulatory requirement)
• Voltage Supply Range: Compatible with 3.3V or higher supply specifications

The identified substitutes maintain the 1310nm wavelength and LC connector configuration. However, differences in data rate, form factor (SFP vs. SFP28), and application classification exist and must be evaluated against specific system requirements.

Parameter Comparison

Engineering Selection Recommendations

AFCT-5710ALZ-C is the primary substitute candidate. Manufactured by ProLabs as an Avago AFCT-5710ALZ compatible module, it maintains identical wavelength (1310nm), connector type (LC), and mounting form factor (Pluggable, SFP). The part carries Active product status with RoHS compliance, ensuring current availability and regulatory alignment. This substitute is suitable for direct replacement in legacy Ethernet systems requiring 1310nm SFP transceiver modules.

AFCT-725SMZ presents a secondary option with significant operational differences. While manufactured by Broadcom Limited with ROHS3 compliance and matching 1310nm wavelength, this part operates at 25Gbps data rate versus the original 1.25Gbd specification and uses SFP28 form factor instead of SFP. The Last Time Buy status indicates limited future availability. This substitute is applicable only in systems capable of supporting higher data rates and SFP28 module slots.

Selection between substitutes depends on system architecture compatibility, particularly regarding form factor acceptance (SFP vs. SFP28) and data rate requirements.

Frequently Asked Questions (FAQ)

Q: Can AFCT-5710ALZ-C be used as a direct replacement for AFCT-5710ALZ?

A: Yes. Both modules share identical wavelength (1310nm), LC connector type, and SFP pluggable form factor. The AFCT-5710ALZ-C is explicitly designed as a compatible alternative and maintains the same physical and optical interface specifications.

Q: Why is AFCT-725SMZ listed as a substitute if it uses SFP28 instead of SFP?

A: AFCT-725SMZ shares the 1310nm wavelength and LC connector configuration. However, SFP28 form factor is physically incompatible with standard SFP slots. This substitute is valid only for systems with SFP28-capable transceiver slots. The higher 25Gbps data rate also requires system support.

Q: What is the significance of the product status differences?

A: AFCT-5710ALZ is Obsolete, indicating no further manufacturing or support. AFCT-5710ALZ-C is Active, ensuring continued availability and technical support. AFCT-725SMZ is Last Time Buy, meaning limited stock remains before discontinuation. For long-term system support, AFCT-5710ALZ-C is the preferred substitute.

Q: Are there voltage supply compatibility concerns?

A: AFCT-5710ALZ operates at 3.14V to 3.47V. AFCT-725SMZ specifies 3.3V, which falls within the original range. AFCT-5710ALZ-C does not specify voltage parameters in available documentation. Verify power supply specifications against system requirements before deployment.

Q: What compliance certifications apply to these substitutes?

A: AFCT-5710ALZ and AFCT-725SMZ are ROHS3 Compliant. AFCT-5710ALZ-C is RoHS Compliant. All three parts carry REACH Unaffected or equivalent status. Verify compliance requirements against your specific regulatory jurisdiction before procurement.
