Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-739ASMZ-OR1 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Wavelength: 1310nm
• Connector Type: LC
• Mounting Type: Pluggable form factor (SFP+ or SFP28)
• Supply Voltage: Compatible operating range

Substitution Logic:

The AFCT-739ASMZ-OR1-C serves as a direct equivalent, maintaining the same 1310nm wavelength, LC connector, and SFP+ pluggable form factor. This substitute is manufactured by ATGBICS and carries an Active product status, providing continued availability.

The AFCT-725SMZ represents a higher-speed alternative operating at 25Gbps with the same 1310nm wavelength and LC connector. This substitute utilizes the SFP28 form factor rather than SFP+, which affects physical mounting compatibility. The AFCT-725SMZ carries a Last Time Buy product status.

Parameter Comparison

Engineering Selection Recommendations

AFCT-739ASMZ-OR1-C Selection:

The AFCT-739ASMZ-OR1-C is the primary substitute for the obsolete AFCT-739ASMZ-OR1. This part maintains identical form factor (SFP+), wavelength (1310nm), and connector type (LC). The AFCT-739ASMZ-OR1-C carries an Active product status, ensuring ongoing availability and support. The part is EAR99 classified and carries no moisture sensitivity level restrictions.

AFCT-725SMZ Selection:

The AFCT-725SMZ operates at a higher data rate (25Gbps) and utilizes the SFP28 form factor. This substitute is applicable only in systems where the SFP28 form factor is supported and higher bandwidth is required or acceptable. The AFCT-725SMZ carries a Last Time Buy status, indicating limited future availability. This part is ROHS3 compliant with MSL 1 rating and carries ECCN 5A991B5A classification.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-739ASMZ-OR1-C be used as a direct replacement for the AFCT-739ASMZ-OR1?

A: Yes. Both parts share identical wavelength (1310nm), connector type (LC), and mounting type (SFP+). The AFCT-739ASMZ-OR1-C is manufactured by ATGBICS and carries Active product status, providing continued availability for the obsolete AFCT-739ASMZ-OR1.

Q: What is the key difference between the AFCT-739ASMZ-OR1-C and AFCT-725SMZ?

A: The primary difference is the form factor and data rate. The AFCT-739ASMZ-OR1-C uses SFP+ form factor at 10Gbps, while the AFCT-725SMZ uses SFP28 form factor at 25Gbps. Both maintain the 1310nm wavelength and LC connector type. Form factor compatibility with the host system determines which substitute is applicable.

Q: Is the AFCT-725SMZ compatible with SFP+ slots?

A: No. The AFCT-725SMZ uses the SFP28 form factor, which is physically distinct from SFP+. The SFP28 form factor is not compatible with SFP+ slots. Verify host system support for SFP28 before selecting this substitute.

Q: What is the voltage supply difference between the main part and substitutes?

A: The AFCT-739ASMZ-OR1 operates within 3.135V to 3.465V. Both substitutes operate at 3.3V, which falls within the original part's operating range. Verify host system voltage supply specifications for compatibility.

Q: Why is the AFCT-725SMZ listed as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for this product. Existing inventory may be available, but future production is not planned. Secure inventory early if this part is selected for new designs.

Q: Are there compliance or certification differences between the substitutes?

A: The AFCT-739ASMZ-OR1-C carries EAR99 classification. The AFCT-725SMZ carries ECCN 5A991B5A classification and is ROHS3 compliant with MSL 1 rating. Verify compliance requirements for your application and region before final selection.
