Parameter Comparison

Engineering Selection Recommendations

The AFCT-5944GZ-C is a valid substitute for the AFCT-5944GZ based on matching electrical specifications and mechanical compatibility. The substitute part is manufactured by ATGBICS and maintains active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete original part.

The substitute operates at 3.3V, which falls within the 3.1V ~ 4.6V supply range of the original part, confirming voltage compatibility. Both parts share identical data rate (2.7Gbps), wavelength (1300nm), and through-hole mounting configuration.

The AFCT-5944GZ-C carries RoHS Compliant certification and maintains REACH Unaffected status, meeting current regulatory requirements for component deployment in new and legacy systems.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-5944GZ-C directly replace the AFCT-5944GZ in existing installations?

A: Yes. The substitute part matches all critical electrical parameters (2.7Gbps data rate, 1300nm wavelength, 3.3V supply voltage within the 3.1V ~ 4.6V range) and mechanical specifications (LC connector, through-hole mounting). Direct substitution is supported for general-purpose applications.

Q: What is the difference between LC Duplex and LC connectors?

A: The original part specifies LC Duplex connectors, while the substitute specifies LC connectors. Both are LC-type connectors suitable for single-mode fiber applications at 1300nm wavelength. Duplex refers to a dual-connector housing; the substitute's single LC designation indicates the connector configuration. Verify your system's physical connector requirements before installation.

Q: Why is the original AFCT-5944GZ obsolete?

A: Product obsolescence reflects end-of-life status from the manufacturer. The AFCT-5944GZ-C, maintained as an active product by ATGBICS, provides continued availability for replacement and repair applications.

Q: Are there compliance differences between the two parts?

A: The AFCT-5944GZ-C carries RoHS Compliant certification, whereas the original part does not specify RoHS status. Both parts maintain REACH Unaffected status. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: What packaging is available for the substitute part?

A: The AFCT-5944GZ-C is supplied in Tray packaging, differing from the original part's packaging specification. Confirm packaging compatibility with your procurement and assembly processes.
