AFCT-739DMZ Equivalent & Substitute Parts

Part Overview

The AFCT-739DMZ is a transceiver module manufactured by Broadcom Limited, designed for Ethernet applications requiring 10GBd data transmission at 1310nm wavelength. This SFP+ pluggable module operates at 3.3V and features LC duplex connectors for optical communication systems.

The AFCT-739DMZ is classified as Obsolete, making it necessary to identify equivalent and substitute parts for ongoing system maintenance and new deployments. Substitute parts must maintain compatibility with existing SFP+ infrastructure while meeting the same electrical and optical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-739DMZ are identified based on the following critical parameters that determine functional compatibility:

• Data Rate: 10GBd (primary electrical specification)
• Wavelength: 1310nm (optical transmission characteristic)
• Voltage Supply: 3.3V (power requirement)
• Connector Type: LC Duplex (physical interface)
• Mounting Type: Pluggable, SFP+ (form factor and slot compatibility)
• Applications: Ethernet (system use case)

Two substitute parts meet these criteria with varying degrees of direct compatibility. The AFCT-739DMZ-C maintains identical electrical and optical specifications as a direct replacement. The AFCT-725SMZ operates at a higher data rate (25Gbps) with the same wavelength and voltage, suitable for systems requiring backward compatibility with 10GBd equipment.

Parameter Comparison

Engineering Selection Recommendations

AFCT-739DMZ-C is the primary substitute for direct replacement applications. This part maintains identical data rate (10Gbps), wavelength (1310nm), voltage supply (3.3V), connector type (LC Duplex), and mounting type (SFP+). The AFCT-739DMZ-C is manufactured by ATGBICS as a Broadcom-compatible module and carries Active product status, ensuring continued availability and support.

AFCT-725SMZ serves as an alternative for systems capable of operating at higher data rates. This part operates at 25Gbps with the same 1310nm wavelength and 3.3V supply voltage. However, the AFCT-725SMZ uses SFP28 form factor rather than SFP+, requiring compatible hardware slots. The AFCT-725SMZ carries Last Time Buy status, indicating limited future availability.

Selection between these substitutes depends on system architecture compatibility. Systems with SFP+ slots require the AFCT-739DMZ-C. Systems with SFP28 capability and higher bandwidth requirements may utilize the AFCT-725SMZ.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-739DMZ-C be used as a direct replacement for the AFCT-739DMZ?

A: Yes. The AFCT-739DMZ-C maintains identical electrical specifications (10Gbps data rate, 1310nm wavelength, 3.3V supply), optical interface (LC Duplex), and form factor (SFP+). Both parts are compatible with the same hardware slots and system configurations.

Q: What is the primary difference between the AFCT-739DMZ-C and AFCT-725SMZ?

A: The AFCT-725SMZ operates at 25Gbps compared to the 10Gbps specification of the AFCT-739DMZ-C. Additionally, the AFCT-725SMZ uses SFP28 form factor rather than SFP+, requiring different hardware slots. Both maintain the same 1310nm wavelength and 3.3V supply voltage.

Q: Can the AFCT-725SMZ be used in systems designed for the AFCT-739DMZ?

A: The AFCT-725SMZ requires SFP28-compatible hardware slots. Systems with only SFP+ slots cannot accommodate this module. Systems with SFP28 capability may use the AFCT-725SMZ, though the higher data rate specification may exceed system requirements.

Q: What is the significance of the product status classifications?

A: The AFCT-739DMZ is Obsolete, indicating discontinued production. The AFCT-739DMZ-C is Active, ensuring ongoing manufacturing and support. The AFCT-725SMZ is Last Time Buy, indicating limited production windows before discontinuation. Active status parts are preferred for new deployments.

Q: Are all substitute parts RoHS3 compliant?

A: The AFCT-739DMZ and AFCT-725SMZ are both ROHS3 Compliant. The AFCT-739DMZ-C RoHS status is not specified in available documentation.
