Key Parameters

Substitute Part Grouping Explanation

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

• Data Rate Compatibility: The substitute must support 2488Mbps or higher data rate capability
• Wavelength: 1300nm is required for optical path compatibility
• Connector Type: LC connector type is mandatory for physical interface compatibility
• Mounting Type: Through-hole mounting is required 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 transceiver functionality must be maintained

The AFCT-5942ALZ-C meets these substitution criteria and is identified as the manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The AFCT-5942ALZ-C is the designated substitute for the obsolete AFCT-5942ALZ. Selection of this alternative is supported by the following factors:

• Product Status: The AFCT-5942ALZ-C maintains Active product status, ensuring ongoing availability and supply chain continuity
• Regulatory Compliance: Both the main part and substitute maintain REACH Unaffected status, confirming equivalent regulatory standing
• RoHS Compliance: The AFCT-5942ALZ-C is RoHS Compliant, meeting modern environmental and manufacturing standards
• Data Rate Capability: The substitute operates at 2.5Gbps, which exceeds the 2488Mbps requirement of the original part, providing operational margin
• Optical Specifications: Wavelength and connector type alignment ensures direct optical path compatibility
• Electrical Compatibility: The 3.3V supply specification of the substitute falls within the operational range of the original 3.1V ~ 4.6V specification

Frequently Asked Questions (FAQ)

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

A: Yes. The AFCT-5942ALZ-C meets all critical substitution parameters: 1300nm wavelength, LC connector type, through-hole mounting, and general-purpose transceiver functionality. The higher data rate (2.5Gbps vs. 2488Mbps) and active product status make it suitable for direct substitution.

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

A: LC Duplex refers to a dual-channel LC connector configuration, while LC indicates a single-channel connector. The AFCT-5942ALZ-C specification lists LC connector type. Verify connector configuration requirements in your system design before implementation.

Q: Is the 3.3V supply of the AFCT-5942ALZ-C compatible with the original 3.1V ~ 4.6V specification?

A: Yes. The 3.3V nominal supply of the substitute falls within the 3.1V ~ 4.6V operating range of the original part, ensuring electrical compatibility.

Q: Why is the AFCT-5942ALZ classified as Obsolete?

A: Obsolete status indicates the part is no longer manufactured by Broadcom Limited. The AFCT-5942ALZ-C provides functional equivalence for systems requiring replacement or redesign.

Q: Are there inventory considerations when selecting the AFCT-5942ALZ-C?

A: The AFCT-5942ALZ-C is available in Active status with 10066 pieces in stock, ensuring procurement availability. The original AFCT-5942ALZ has 1034 pieces available but is subject to obsolescence constraints.
