Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-5942TGZ is determined by the following critical parameters:

• Data Rate Compatibility: The substitute must support 2488Mbps or higher data rates to ensure functional equivalence in SONET OC48/SDH applications.
• Wavelength: 1300nm wavelength is mandatory for optical path compatibility.
• Connector Type: LC connector configuration is required for physical and optical interface compatibility.
• Mounting Type: Through Hole mounting must be maintained for PCB integration.
• Voltage Supply Range: The substitute must operate within or be compatible with the 3.1V ~ 4.6V supply specification.
• Application Category: General Purpose classification ensures broad system compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AFCT-5942TGZ-C qualifies as a functional substitute based on the following criteria:

• Data Rate: The substitute operates at 2.5Gbps, which exceeds the 2488Mbps requirement and maintains backward compatibility with SONET OC48/SDH applications.
• Wavelength Match: Both parts operate at 1300nm, ensuring optical path compatibility without modification.
• Connector and Mounting: LC connector with Through Hole mounting matches the original specification.
• Voltage Compatibility: The substitute operates at 3.3V, which falls within the 3.1V ~ 4.6V supply range of the original part.
• Product Status: The substitute is classified as Active, providing ongoing availability and support compared to the obsolete original part.
• Compliance: Both parts maintain REACH Unaffected status, ensuring regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can AFCT-5942TGZ-C be used as a direct replacement for AFCT-5942TGZ?

A: Yes. The substitute meets all critical electrical and mechanical parameters: matching wavelength (1300nm), compatible data rate (2.5Gbps exceeds 2488Mbps requirement), compatible voltage supply (3.3V within 3.1V ~ 4.6V range), and identical connector and mounting specifications.

Q: What is the difference in data rate between the original and substitute?

A: The original part operates at 2488Mbps, while the substitute operates at 2.5Gbps (2500Mbps). This represents a 0.48% increase in data rate capacity, which is operationally transparent in SONET OC48/SDH systems and provides additional performance margin.

Q: Are there packaging differences between these parts?

A: The original part is specified with "-" packaging, while the substitute uses Tray packaging. Both are Through Hole mounted modules suitable for PCB integration.

Q: Why is the original part listed as obsolete?

A: The AFCT-5942TGZ is classified as obsolete by Broadcom Limited. The AFCT-5942TGZ-C substitute is maintained as an Active product by ATGBICS, ensuring continued availability for system maintenance and new deployments.

Q: Are there compliance or certification differences?

A: Both parts maintain REACH Unaffected status. The substitute includes RoHS Compliant certification, providing additional environmental compliance assurance.
