Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-739JAMZ are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Wavelength: 1310nm (maintained across all substitutes)
• Connector Type: LC (maintained across all substitutes)
• Mounting Type: Pluggable form factor (SFP+ or SFP28)
• Voltage Supply Range: Compatible with 3.3V nominal operation

Substitute Classification:

Direct Equivalent: AFCT-739JAMZ-C (ATGBICS manufacturer) maintains the SFP+ form factor and 1310nm wavelength specification. This part operates at 3.3V supply voltage and is classified as Active product status, providing current availability for legacy system support.

Form Factor Variant: AFCT-725SMZ (Broadcom Limited) operates at 25Gbps data rate with SFP28 form factor, maintaining the 1310nm wavelength and LC connector type. This part represents a higher-speed alternative within the same wavelength family and is classified as Last Time Buy status.

Parameter Comparison

Engineering Selection Recommendations

AFCT-739JAMZ-C Selection Criteria:

The AFCT-739JAMZ-C is the primary direct equivalent for the obsolete AFCT-739JAMZ. Both parts maintain SFP+ form factor and 1310nm wavelength operation. The AFCT-739JAMZ-C is manufactured by ATGBICS and carries Active product status, ensuring current availability. This part is RoHS Compliant and carries EAR99 ECCN classification. The AFCT-739JAMZ-C operates at 3.3V nominal supply voltage, which falls within the acceptable range of the original part's 3.135V to 3.465V specification. Selection of this part is appropriate for direct replacement in legacy Ethernet systems requiring SFP+ transceiver modules.

AFCT-725SMZ Selection Criteria:

The AFCT-725SMZ represents a higher-speed alternative within the 1310nm wavelength family. This part operates at 25Gbps data rate in SFP28 form factor, compared to the original 9.8304GBd SFP+ specification. The AFCT-725SMZ is manufactured by Broadcom Limited and carries Last Time Buy product status. This part is ROHS3 Compliant with ECCN 5A991B5A classification. Selection of this part is appropriate only for systems with SFP28 port compatibility and applications requiring 25Gbps data rate capability. Form factor incompatibility with SFP+ ports precludes direct substitution in legacy equipment.

Frequently Asked Questions (FAQ)

Q: Can AFCT-739JAMZ-C be used as a direct replacement for AFCT-739JAMZ?

A: Yes. Both parts maintain identical form factor (SFP+), wavelength (1310nm), and connector type (LC). The AFCT-739JAMZ-C operates at 3.3V supply voltage, which is within the acceptable operating range of the original part (3.135V to 3.465V). The AFCT-739JAMZ-C is currently in Active product status, providing supply availability for legacy system support.

Q: What is the primary difference between AFCT-739JAMZ-C and AFCT-725SMZ?

A: The AFCT-739JAMZ-C maintains SFP+ form factor with 3Gbps data rate, while AFCT-725SMZ uses SFP28 form factor with 25Gbps data rate. Both parts operate at 1310nm wavelength with LC connectors. Form factor differences prevent physical interchangeability between SFP+ and SFP28 ports.

Q: Can AFCT-725SMZ be installed in an SFP+ port?

A: No. The AFCT-725SMZ uses SFP28 form factor, which is physically incompatible with SFP+ ports. SFP28 connectors and modules are not interchangeable with SFP+ equipment.

Q: What compliance certifications apply to the substitute parts?

A: AFCT-739JAMZ-C is RoHS Compliant and REACH Unaffected. AFCT-725SMZ is ROHS3 Compliant. Both parts meet current regulatory requirements for electronic component manufacturing and distribution.

Q: Why is the original AFCT-739JAMZ classified as Obsolete?

A: Obsolete classification indicates the part is no longer manufactured or supported by the original manufacturer. Identifying equivalent and substitute parts ensures continued system functionality and supply chain continuity for legacy equipment.

Q: Are there inventory considerations when selecting a substitute?

A: AFCT-739JAMZ-C is available with 4756 pieces in stock. AFCT-725SMZ is available with 940 pieces in stock. Both parts are available as new original components. Inventory levels should be verified at time of procurement.
