AFCT-5701LZ Equivalent & Substitute Parts

Part Overview

The AFCT-5701LZ is a transceiver module manufactured by Broadcom Limited, designed for Ethernet applications with a data rate of 1.25Gbd and 1310nm wavelength. This SFP pluggable module operates at 3.14V to 3.47V supply voltage with LC duplex connector configuration. The product is currently obsolete, making identification of equivalent and substitute parts essential for system maintenance, legacy system support, and component procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-5701LZ are identified based on the following critical parameters that determine functional compatibility:

• 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 substitutes maintain the 1310nm wavelength and LC connector configuration essential for optical path compatibility. Differences in data rate (1.25Gbd vs. 25Gbps) and form factor (SFP vs. SFP28) represent performance enhancements and backward compatibility considerations within the SFP transceiver family.

Parameter Comparison

Engineering Selection Recommendations

AFCT-5701LZ-C (ProLabs) is the primary substitute for direct replacement applications. This part is manufactured as a compatible equivalent to the original AFCT-5701LZ, maintains identical wavelength (1310nm) and connector type (LC), and operates in the same SFP form factor. The part carries active product status and RoHS compliance certification, making it suitable for new procurement and legacy system support.

AFCT-725SMZ (Broadcom Limited) represents a performance-enhanced alternative for applications where higher data rate capability (25Gbps) is acceptable. This part maintains the 1310nm wavelength and LC connector but uses the SFP28 form factor. The transition from SFP to SFP28 requires verification of host equipment compatibility. This part is in Last Time Buy status, indicating limited future availability.

For systems requiring exact form factor and performance matching, AFCT-5701LZ-C is the recommended selection. For systems capable of supporting SFP28 modules and higher data rates, AFCT-725SMZ provides an upgrade path with extended component lifecycle.

Frequently Asked Questions (FAQ)

Q: Can AFCT-725SMZ be used as a direct replacement for AFCT-5701LZ?

A: AFCT-725SMZ shares the 1310nm wavelength and LC connector type but differs in form factor (SFP28 vs. SFP) and data rate (25Gbps vs. 1.25Gbd). Direct substitution requires host equipment compatibility with SFP28 modules. Verify equipment specifications before implementation.

Q: What is the difference between AFCT-5701LZ and AFCT-5701LZ-C?

A: AFCT-5701LZ-C is a ProLabs-manufactured equivalent designed for compatibility with the original Broadcom AFCT-5701LZ. Both maintain identical wavelength, connector type, and SFP form factor. AFCT-5701LZ-C carries active product status, while the original is obsolete.

Q: Are all substitute parts RoHS compliant?

A: Yes. AFCT-5701LZ-C and AFCT-725SMZ both carry RoHS compliance certifications (RoHS Compliant and ROHS3 Compliant respectively), meeting environmental and regulatory requirements.

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 component. Existing inventory may be available, but future procurement will not be possible. For long-term system support, AFCT-5701LZ-C (Active status) is the recommended selection.

Q: Can I use these parts interchangeably in my system?

A: Interchangeability depends on host equipment specifications. All three parts operate at 1310nm with LC connectors, but form factor differences (SFP vs. SFP28) and data rate variations require verification against your system's transceiver module slot specifications and supported data rates.
