Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-701ASDZ is determined by the following critical parameters:

• Data Rate Compatibility: The substitute must support 10Gbps or equivalent data rates (10.312Gbd nominal)
• Wavelength: 1310nm single-mode fiber operation is required
• Supply Voltage: 3.3V operation is mandatory
• Connector Type: LC connector configuration for optical interface
• Mounting Type: SFP or SFP+ pluggable form factor
• Application Domain: Ethernet or general-purpose transceiver functionality

The AFCT-701ASDZ-C from ATGBICS meets these substitution criteria while offering active product status and improved availability.

Engineering Selection Recommendations

The AFCT-701ASDZ-C is qualified as a direct substitute based on the following engineering criteria:

Product Status: The substitute part maintains active product status, ensuring continued availability and manufacturing support. The original AFCT-701ASDZ is obsolete, creating supply chain risk for new deployments and field replacements.

Compliance & Certifications: The AFCT-701ASDZ-C carries EAR99 classification, providing broader export flexibility compared to the original part's 5A991B5A ECCN designation. Both parts are REACH-compliant within their respective regulatory frameworks.

Operational Compatibility: Both parts operate at identical wavelength (1310nm) and supply voltage (3.3V), with data rates within the 10Gbps class. The SFP+ form factor of the substitute provides backward compatibility with SFP-capable host equipment while offering enhanced performance headroom.

Inventory Availability: The substitute part (AFCT-701ASDZ-C) maintains significantly higher stock levels (6135 units) compared to the original part, reducing procurement lead times and supporting production schedules.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-701ASDZ-C be used as a direct replacement in equipment designed for the AFCT-701ASDZ?

A: Yes. Both parts operate at 1310nm wavelength, 3.3V supply voltage, and support 10Gbps-class Ethernet data rates. The SFP+ form factor is backward compatible with SFP host interfaces. Verify host equipment specifications for SFP+ module support.

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

A: SFP+ is an enhanced version of the SFP standard supporting higher data rates and improved thermal management. SFP+ modules are physically compatible with SFP slots on most modern equipment, though older SFP-only interfaces may have compatibility limitations. Consult equipment documentation for specific support.

Q: Why is the original AFCT-701ASDZ classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. This necessitates transition to active alternatives for new procurements and long-term system reliability.

Q: Are there any packaging differences between the main part and substitute?

A: The AFCT-701ASDZ ships in standard packaging, while the AFCT-701ASDZ-C is supplied in tray packaging. Both formats are suitable for production environments and field deployment.

Q: What compliance certifications apply to both parts?

A: The AFCT-701ASDZ carries REACH Unaffected status with ECCN 5A991B5A. The AFCT-701ASDZ-C is REACH-compliant with EAR99 classification, providing equivalent regulatory compliance for commercial applications.
