Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-57D3ANMZ is determined by the following critical parameters:

• Data Rate compatibility: The substitute must support the required data rates or operate at equivalent or higher performance levels
• Wavelength: Must match 1310nm for optical path compatibility
• Supply Voltage: Must operate at 3.3V to ensure power supply compatibility
• Connector Type: Must use LC connectivity for physical interface compatibility
• Mounting Type: Must be SFP+ pluggable format for slot compatibility
• Form Factor: Must maintain SFP+ physical dimensions for mechanical fit

The AFCT-57D3ANMZ-C qualifies as a substitute based on these parameters. While it operates at a higher data rate (10Gbps), it maintains compatibility across all critical electrical and mechanical specifications required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The AFCT-57D3ANMZ-C is available as an active product with current manufacturing support, addressing the obsolescence status of the original AFCT-57D3ANMZ. Both modules maintain identical supply voltage (3.3V), wavelength (1310nm), and SFP+ form factor requirements. The substitute operates at 10Gbps, which exceeds the maximum data rate of the original module, ensuring backward compatibility with existing system configurations. ROHS3 compliance is confirmed for the main part; compliance status for the substitute should be verified during procurement if regulatory requirements mandate it.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-57D3ANMZ-C directly replace the AFCT-57D3ANMZ in existing systems?

A: Yes. Both modules share identical supply voltage (3.3V), wavelength (1310nm), connector type (LC), and SFP+ pluggable form factor. The substitute's higher data rate (10Gbps) is backward compatible with systems operating at the original module's data rates (2.125GBd, 4.25GBd, 8.5GBd).

Q: What is the primary reason for seeking a substitute?

A: The AFCT-57D3ANMZ is classified as obsolete. The AFCT-57D3ANMZ-C is an active product with current manufacturing availability, ensuring long-term supply chain continuity.

Q: Are there packaging differences between these modules?

A: The main part packaging is not specified in available data. The substitute is supplied in tray packaging. Packaging format should be confirmed during procurement to ensure compatibility with assembly and storage requirements.

Q: What parameters must remain constant for substitution?

A: Supply voltage (3.3V), wavelength (1310nm), connector type (LC), and mounting type (SFP+ pluggable) are non-negotiable for direct substitution. These parameters ensure electrical and mechanical compatibility with host equipment.

Q: Is RoHS compliance a factor in substitution?

A: The main part is ROHS3 compliant. The substitute's RoHS status is not specified in available documentation. If regulatory compliance is required, this must be confirmed with the supplier before procurement.
