Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-739ASMZ-EX2 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Wavelength: 1310nm (maintained across all substitutes)
• Connector Type: LC (maintained across all substitutes)
• Mounting Type: Pluggable form factor (SFP+ or SFP28)
• Voltage Supply: 3.3V nominal operation (compatible with original 3.135V ~ 3.465V range)

Substitute Parts Identified:

1. AFCT-739ASMZ-EX2-C (Manufacturer: ATGBICS) – Direct form factor equivalent with matching SFP+ mounting and 10Gbps data rate
2. AFCT-725SMZ (Manufacturer: Broadcom Limited) – Higher data rate variant (25Gbps) with SFP28 form factor and matching 1310nm wavelength

Parameter Comparison

Engineering Selection Recommendations

AFCT-739ASMZ-EX2-C Selection Criteria:

This substitute is classified as Active product status, ensuring ongoing manufacturer support and availability. The part maintains identical data rate (10Gbps equivalent to 10.313GBd), wavelength (1310nm), and SFP+ form factor. Supply voltage of 3.3V operates within the original part's specified range. This substitute provides direct functional replacement for systems requiring 10Gbps Ethernet SFP+ transceiver modules with 1310nm wavelength and LC connector configuration.

AFCT-725SMZ Selection Criteria:

This substitute is classified as Last Time Buy status, indicating limited future availability. The part operates at 25Gbps data rate, representing a higher-speed variant. The SFP28 form factor differs from the original SFP+ mounting type. This substitute is applicable only for systems capable of supporting 25Gbps operation and equipped with SFP28 module slots. Wavelength (1310nm) and connector type (LC) remain compatible with the original specification.

Frequently Asked Questions (FAQ)

Q: Can AFCT-739ASMZ-EX2-C be used as a direct replacement for AFCT-739ASMZ-EX2?

A: Yes. Both parts operate at 10Gbps data rate with 1310nm wavelength, LC connector, and SFP+ pluggable form factor. The AFCT-739ASMZ-EX2-C is manufactured by ATGBICS and maintains Active product status, providing functional equivalence for Ethernet applications.

Q: What is the primary difference between AFCT-739ASMZ-EX2-C and AFCT-725SMZ?

A: The AFCT-725SMZ operates at 25Gbps data rate compared to 10Gbps for the AFCT-739ASMZ-EX2-C. Additionally, AFCT-725SMZ uses SFP28 form factor while AFCT-739ASMZ-EX2-C uses SFP+ form factor. Both maintain 1310nm wavelength and LC connector compatibility.

Q: Can AFCT-725SMZ be installed in equipment designed for AFCT-739ASMZ-EX2?

A: Physical installation of AFCT-725SMZ requires SFP28 module slots. Equipment designed for SFP+ modules cannot accommodate SFP28 form factor. Verify equipment specifications before substitution.

Q: What is the significance of the Obsolete product status for AFCT-739ASMZ-EX2?

A: Obsolete status indicates the original part is no longer manufactured. Substitute parts with Active or Last Time Buy status provide continued access to equivalent functionality for system maintenance and new deployments.

Q: Are there voltage compatibility concerns when substituting these parts?

A: The original part operates at 3.135V to 3.465V. Both substitutes operate at 3.3V nominal, which falls within the original specification range. No voltage compatibility issues exist.

Q: What packaging options are available for these substitutes?

A: AFCT-739ASMZ-EX2-C is supplied in Tray packaging. AFCT-725SMZ is supplied in Bulk packaging. Verify packaging requirements for your procurement and handling procedures.
