Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-57J5APZ is determined by the following critical parameters:

• Data Rate Compatibility: The substitute must support 3Gbps or higher to accommodate the original 3.072Gbps specification
• Wavelength: 1310nm single-mode operation is required
• Supply Voltage: 3.3V operation is mandatory
• Connector Type: LC Duplex connectors ensure physical and optical compatibility
• Form Factor: SFP or SFP+ pluggable modules maintain mechanical interchangeability
• Application Domain: General-purpose and networking applications confirm functional alignment

The AFCT-57J5APZ-C, manufactured by ATGBICS, meets these substitution criteria as a Broadcom-compatible alternative.

Parameter Comparison

Engineering Selection Recommendations

The AFCT-57J5APZ-C is the designated manufacturer-recommended substitute for the obsolete AFCT-57J5APZ. Selection of this alternative is justified by:

• Product Status: The original part is obsolete; the substitute is active and available in production quantities (8372 pcs in stock)
• Compliance Alignment: Both parts maintain REACH compliance status; the substitute carries EAR99 classification
• Electrical Compatibility: Matching 3.3V supply voltage and 1310nm wavelength ensure direct functional replacement
• Physical Interchangeability: LC Duplex connectors and pluggable form factors enable mechanical compatibility in existing SFP/SFP+ slots
• Data Rate Margin: The substitute's 3Gbps capability accommodates the original 3.072Gbps requirement with operational headroom

Frequently Asked Questions (FAQ)

Q: Can the AFCT-57J5APZ-C directly replace the AFCT-57J5APZ in existing systems?

A: Yes. Both modules share identical wavelength (1310nm), supply voltage (3.3V), and connector type (LC Duplex). The substitute's 3Gbps data rate exceeds the original 3.072Gbps specification, ensuring compatibility. Verify that your system's SFP/SFP+ slot supports the pluggable form factor.

Q: What is the difference between SFP and SFP+ form factors?

A: SFP+ is a higher-density variant of SFP with enhanced electrical performance. SFP+ slots are backward-compatible with SFP modules, allowing the AFCT-57J5APZ-C (SFP+) to operate in systems designed for the original SFP module.

Q: Why is the original part classified as obsolete?

A: Broadcom Limited has discontinued the AFCT-57J5APZ. The AFCT-57J5APZ-C represents the active, supported alternative for new procurements and system maintenance.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts maintain REACH compliance. The original carries ECCN 5A991B5A; the substitute carries EAR99 classification. Verify export control requirements for your application jurisdiction.

Q: What packaging options are available for the substitute?

A: The AFCT-57J5APZ-C is supplied in Tray packaging, suitable for production and bulk procurement workflows.
