Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-5701PZ is determined by the following critical parameters:

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

The identified substitute parts maintain the 1310nm wavelength and LC connector specifications. However, differences in data rate, form factor (SFP vs. SFP28), and voltage specifications must be evaluated for system compatibility.

Parameter Comparison

Engineering Selection Recommendations

AFCT-5701PZ-C (ProLabs): This substitute is the primary equivalent option. Manufactured by ProLabs as an Avago AFCT-5701PZ compatible module, it maintains identical form factor (SFP), connector type (LC), and wavelength (1310nm). The product is currently Active, ensuring ongoing availability and support. RoHS compliance is confirmed. This part is suitable for direct replacement in systems requiring 1310nm SFP transceiver modules.

AFCT-725SMZ (Broadcom Limited): This substitute shares the 1310nm wavelength and LC connector but differs in form factor (SFP28 vs. SFP) and data rate (25Gbps vs. 1.25Gbd). The SFP28 form factor is not backward compatible with SFP slots. This part is classified as Last Time Buy, indicating limited future availability. Selection of this substitute requires system-level compatibility verification for form factor and data rate requirements.

Frequently Asked Questions (FAQ)

Q: Can AFCT-5701PZ-C be used as a direct replacement for AFCT-5701PZ?

A: Yes. AFCT-5701PZ-C maintains the same wavelength (1310nm), connector type (LC), and mounting type (Pluggable, SFP). It is explicitly marketed as an Avago AFCT-5701PZ compatible module and is currently in Active product status.

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

A: AFCT-725SMZ shares the critical optical parameters (1310nm wavelength, LC connector) but operates at a higher data rate (25Gbps) in a different form factor (SFP28). It is included as a substitute only for systems with SFP28 slots and applications requiring higher data rates. SFP and SFP28 modules are not interchangeable due to physical form factor differences.

Q: What is the significance of the Obsolete status for AFCT-5701PZ?

A: Obsolete status indicates the part is no longer manufactured and existing inventory is limited. Substitute parts with Active or Last Time Buy status should be prioritized for new designs or long-term system support.

Q: Are all substitute parts RoHS compliant?

A: Yes. AFCT-5701PZ-C is RoHS Compliant, and AFCT-725SMZ is ROHS3 Compliant, matching the compliance requirements of the original AFCT-5701PZ.

Q: What voltage supply range should be verified when selecting a substitute?

A: The original AFCT-5701PZ operates at 3.14V to 3.47V. AFCT-5701PZ-C does not specify voltage requirements but is designed as a compatible replacement. AFCT-725SMZ operates at 3.3V, which falls within the original voltage range. System power supply specifications should be verified before final selection.
