Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-5943GZ is determined by strict alignment of the following critical parameters:

• Data Rate: 2.7Gbps (exact match required)
• Wavelength: 1300nm (exact match required)
• Connector Type: LC Duplex (exact match required)
• Mounting Type: Through Hole (exact match required)
• Voltage - Supply: Compatible range (3.1V ~ 4.6V for original; 3.3V for substitute falls within acceptable operating range)

The AFCT-5943GZ-C qualifies as a direct substitute based on these parameters. This part is manufactured by ATGBICS as a Broadcom-compatible module, maintaining electrical and mechanical compatibility while offering active product status and improved availability.

Engineering Selection Recommendations

The AFCT-5943GZ-C is the qualified substitute for the obsolete AFCT-5943GZ. Selection should be based on the following factors:

Product Status: The original AFCT-5943GZ is obsolete. The AFCT-5943GZ-C maintains active product status, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: The substitute part carries RoHS Compliance certification and maintains REACH Unaffected status, consistent with the original. Both parts are classified under ECCN regulations appropriate for optical transceiver modules.

Electrical Compatibility: The substitute operates at 3.3V, which falls within the original part's specified supply voltage range of 3.1V ~ 4.6V, ensuring direct electrical compatibility in existing designs.

Mechanical & Optical Specifications: Identical data rate (2.7Gbps), wavelength (1300nm), connector type (LC Duplex), and mounting configuration (Through Hole) confirm mechanical and optical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-5943GZ-C be used as a direct replacement for the AFCT-5943GZ?

A: Yes. The AFCT-5943GZ-C meets all critical substitution criteria: identical data rate, wavelength, connector type, and mounting configuration. The supply voltage of 3.3V is within the original part's operating range of 3.1V ~ 4.6V.

Q: What is the primary reason to substitute the AFCT-5943GZ?

A: The original part is classified as obsolete. The AFCT-5943GZ-C provides an active, readily available alternative that maintains full electrical and mechanical compatibility.

Q: Are there packaging differences between the original and substitute?

A: The original AFCT-5943GZ packaging is not specified in the technical data. The AFCT-5943GZ-C is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the substitute part meet environmental compliance standards?

A: Yes. The AFCT-5943GZ-C is RoHS Compliant and maintains REACH Unaffected status, consistent with regulatory requirements for electronic components.

Q: What is the Moisture Sensitivity Level (MSL) of the substitute part?

A: The AFCT-5943GZ-C lists MSL as Not Applicable, whereas the original specifies MSL 3 (168 Hours). Confirm handling and storage requirements with your assembly partner if MSL-specific protocols are required.
