Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-57R5ATPZ is determined by the following critical parameters:

• Data Rate: 4.25Gbps
• Wavelength: 1310nm
• Voltage - Supply: 3.3V
• Connector Type: LC (Duplex or standard)
• Mounting Type: SFP or SFP+ pluggable format
• Applications: General Purpose

The substitute part AFCT-57R5ATPZ-C matches all critical electrical and optical parameters required for functional equivalence. Both parts operate at identical data rates, wavelengths, and supply voltages, with compatible connector and mounting specifications suitable for general-purpose deployment.

Parameter Comparison

Engineering Selection Recommendations

The AFCT-57R5ATPZ-C is the manufacturer-recommended substitute for the obsolete AFCT-57R5ATPZ. Both modules maintain electrical and optical compatibility across all critical parameters: identical data rate (4.25Gbps), wavelength (1310nm), and supply voltage (3.3V).

The substitute part carries Active product status, ensuring ongoing availability and support. The AFCT-57R5ATPZ-C is classified under ECCN EAR99, compared to the original part's ECCN 5A991B5A, reflecting current export compliance standards.

Component selection should prioritize the active substitute part for new deployments and system maintenance where the original obsolete module is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-57R5ATPZ-C directly replace the AFCT-57R5ATPZ?

A: Yes. Both modules operate at 4.25Gbps with 1310nm wavelength and 3.3V supply voltage. The electrical and optical parameters are identical, supporting direct substitution in general-purpose applications.

Q: What is the difference between SFP and SFP+ mounting types?

A: SFP+ is a higher-density variant of the SFP form factor, designed to support higher data rates. Both formats are pluggable and compatible with standard LC connectors. The AFCT-57R5ATPZ-C operates within the electrical specifications of both form factors at 4.25Gbps.

Q: Why is the original part classified as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued production. The AFCT-57R5ATPZ-C remains in active production, making it the appropriate choice for ongoing component procurement.

Q: Are there compliance differences between the two parts?

A: The AFCT-57R5ATPZ-C is classified as REACH Unaffected and carries ECCN EAR99 designation. Both classifications support standard commercial deployment without additional regulatory restrictions for general-purpose applications.

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

A: The AFCT-57R5ATPZ-C is classified as Not Applicable for MSL, indicating no moisture sensitivity constraints during storage and handling.
