Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Wavelength: 1310nm (maintained across all substitutes)
• Connector Type: LC Duplex (maintained for mechanical compatibility)
• Mounting Type: Pluggable, SFP form factor (maintained for slot compatibility)
• Applications: Ethernet or General Purpose (compatible operational context)

Secondary Considerations:

• Data Rate: 1.25Gbd (baseline requirement; higher rates acceptable in forward-compatible systems)
• Voltage Supply: Operating range must be compatible with system power delivery specifications
• RoHS and REACH Compliance: Regulatory alignment for procurement and deployment

The identified substitutes maintain the core wavelength, connector, and form factor specifications while accommodating variations in data rate capability and voltage supply ranges based on system requirements.

Parameter Comparison

Engineering Selection Recommendations

AFCT-5710APZ-C (ATGBICS) is the primary substitute for direct replacement applications. This part maintains identical data rate (1.25Gbps), wavelength (1310nm), and connector configuration (LC Duplex) as the original AFCT-5710APZ. The part is currently Active in product status, ensuring ongoing availability and supply chain stability. It is RoHS Compliant and REACH Unaffected, meeting regulatory requirements. The primary design consideration is the elevated supply voltage requirement (5V versus 3.14V–3.47V), which must be verified against system power delivery specifications before deployment.

AFCT-725SMZ (Broadcom Limited) serves as an alternative for applications requiring higher data rate capability. This SFP28 module operates at 25Gbps with the same 1310nm wavelength and maintains Broadcom manufacturing continuity. The part is in Last Time Buy status, indicating limited future availability. The form factor change from SFP to SFP28 and the connector specification change (LC versus LC Duplex) require mechanical and electrical system compatibility verification. Supply voltage (3.3V) is within a compatible range relative to the original specification.

Selection between substitutes depends on system architecture, available power delivery, and mechanical slot compatibility. Both substitutes maintain the critical 1310nm wavelength and Ethernet/General Purpose application context.

Frequently Asked Questions (FAQ)

Q: Can AFCT-5710APZ-C be used as a direct plug-in replacement for AFCT-5710APZ?

A: AFCT-5710APZ-C maintains the same SFP form factor and LC Duplex connector configuration, enabling mechanical compatibility. However, the supply voltage requirement (5V) differs from the original specification (3.14V–3.47V). System power delivery must be verified to support the higher voltage before deployment.

Q: What is the primary difference between AFCT-725SMZ and AFCT-5710APZ?

A: AFCT-725SMZ is an SFP28 module with a 25Gbps data rate, compared to the SFP form factor and 1.25Gbd rate of AFCT-5710APZ. Both operate at 1310nm wavelength. The form factor change (SFP to SFP28) and connector specification change (LC versus LC Duplex) require system slot and connector compatibility verification.

Q: Why is wavelength consistency important in substitute selection?

A: Wavelength determines optical compatibility with system transceivers, fiber optic cables, and network infrastructure. All identified substitutes maintain 1310nm operation to ensure optical path compatibility with existing system components.

Q: What does "Last Time Buy" status mean for AFCT-725SMZ?

A: Last Time Buy indicates that Broadcom has announced end-of-life for this product. Existing inventory may be available, but future procurement will not be possible. This status affects long-term supply chain planning for systems requiring this specific module.

Q: Are all substitutes RoHS compliant?

A: Yes. AFCT-5710APZ-C is RoHS Compliant, and AFCT-725SMZ is ROHS3 Compliant. Both meet regulatory requirements for hazardous substance restrictions.
