Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-5710LZ is determined by the following critical parameters:

Primary Compatibility Criteria:

• Wavelength: 1310nm (must match)
• Connector Type: LC (must match)
• Mounting Type: Pluggable SFP form factor (must match)
• Applications: Ethernet (must match)
• RoHS Status: ROHS3 Compliant (must match)

Secondary Consideration Parameters:

• Data Rate: 1.25Gbd (baseline requirement)
• Voltage Supply Range: 3.14V ~ 3.47V (baseline requirement)

The identified substitute parts maintain the core wavelength, connector, and form factor specifications while operating within compatible electrical parameters and compliance frameworks.

Engineering Selection Recommendations

AFCT-5710LZ-C (Primary Substitute)

This part is the recommended substitute for the obsolete AFCT-5710LZ. Both modules operate at 1310nm wavelength with LC connector configuration in standard SFP form factor for Ethernet applications. The AFCT-5710LZ-C is currently in active product status with 10,553 units in stock, ensuring long-term availability. Both parts maintain ROHS3 compliance and REACH unaffected status. The supply voltage of 3.3V falls within the operational envelope of systems designed for the original 3.14V to 3.47V specification.

AFCT-725SMZ (Secondary Consideration)

This part shares the 1310nm wavelength and LC connector with the main part but operates in SFP28 form factor at 25Gbps data rate. The SFP28 form factor is not directly compatible with standard SFP slots, requiring form factor conversion or system redesign. This part is classified as Last Time Buy, indicating limited future availability. Selection of this part requires confirmation that the target system supports SFP28 modules or includes appropriate adapter infrastructure.

Frequently Asked Questions (FAQ)

Q: Can AFCT-5710LZ-C directly replace AFCT-5710LZ in existing systems?

A: Yes. Both modules operate at 1310nm wavelength with LC connectors in standard SFP pluggable form factor. The 3.3V supply voltage of the AFCT-5710LZ-C is compatible with systems designed for the 3.14V to 3.47V range of the original part. Both maintain ROHS3 compliance and REACH unaffected status.

Q: What is the difference between SFP and SFP28 form factors?

A: SFP (Small Form-factor Pluggable) and SFP28 are different physical form factors. SFP modules are smaller and operate at lower data rates (1.25Gbd in this case), while SFP28 modules are larger and support higher data rates (25Gbps). These form factors are not mechanically interchangeable without adapter infrastructure.

Q: Why is AFCT-725SMZ listed as a substitute if it uses SFP28 form factor?

A: AFCT-725SMZ shares critical optical parameters (1310nm wavelength, LC connector) with the main part but operates in a different form factor. It is listed as a substitute only for applications where SFP28 infrastructure is available or where form factor conversion is feasible.

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

A: Last Time Buy indicates that the manufacturer has announced end-of-life for this product. Current inventory (940 units) represents the final available stock. Future procurement of this part may not be possible.

Q: Are there compliance differences between the substitute parts?

A: All three parts maintain ROHS3 compliance. The main part and AFCT-5710LZ-C both have confirmed REACH unaffected status. AFCT-725SMZ carries the same ECCN and HTSUS classifications as the main part. Moisture sensitivity levels differ: the main part specifies MSL 3 (168 hours), AFCT-725SMZ specifies MSL 1 (unlimited), and AFCT-5710LZ-C has vendor-undefined MSL.
