Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-5705PZ 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 specifications
• RoHS Compliance: ROHS3 or equivalent compliance status

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

Parameter Comparison

Engineering Selection Recommendations

AFCT-5705PZ-C is the primary substitute for direct replacement applications. This ProLabs module is manufactured as an Avago AFCT-5705PZ compatible part, maintaining identical wavelength (1310nm), connector type (LC), and mounting form factor (SFP). The part is currently Active in product status, ensuring ongoing availability and support. RoHS compliance is maintained. This substitute is suitable for applications requiring form-factor and optical compatibility with the original AFCT-5705PZ.

AFCT-725SMZ is a higher-performance alternative for applications capable of supporting increased data rates. This Broadcom Limited SFP28 module operates at 25Gbps compared to the original 1.25Gbd specification, with matching 1310nm wavelength and LC connector. The form factor difference (SFP28 vs. SFP) and elevated data rate require verification of host equipment compatibility. Product status is Last Time Buy, indicating limited future availability. This substitute is applicable only when host equipment supports SFP28 form factor and higher data rates.

Frequently Asked Questions (FAQ)

Q: Can AFCT-725SMZ be used as a direct replacement for AFCT-5705PZ?

A: AFCT-725SMZ shares the 1310nm wavelength and LC connector with AFCT-5705PZ but differs in form factor (SFP28 vs. SFP) and data rate (25Gbps vs. 1.25Gbd). Direct substitution requires host equipment compatibility with SFP28 modules and support for 25Gbps operation. Physical form factor differences may prevent installation in SFP-only slots.

Q: What is the difference between AFCT-5705PZ and AFCT-5705PZ-C?

A: AFCT-5705PZ-C is a ProLabs-manufactured compatible module designed to replicate the functionality of the original Broadcom AFCT-5705PZ. Both maintain identical wavelength (1310nm), connector type (LC), and SFP form factor. AFCT-5705PZ-C is currently Active in product status, whereas the original is Obsolete. The compatible module is suitable for direct replacement in existing systems.

Q: Are all substitute parts RoHS compliant?

A: Yes. AFCT-5705PZ-C and AFCT-725SMZ both maintain RoHS compliance (RoHS Compliant and ROHS3 Compliant respectively), matching the compliance status of the original AFCT-5705PZ.

Q: What voltage supply considerations apply to substitutes?

A: The original AFCT-5705PZ operates at 3.14V to 3.47V. AFCT-725SMZ operates at 3.3V, which falls within the original voltage range. AFCT-5705PZ-C voltage specifications are not provided in available documentation. Verify host equipment voltage supply compatibility before substitution.

Q: Which substitute offers the best availability?

A: AFCT-5705PZ-C is currently Active in product status with 96,621 units in stock, offering the highest availability. AFCT-725SMZ is Last Time Buy status with 940 units available. The original AFCT-5705PZ is Obsolete with 8,490 units remaining in inventory.
