Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-739DMZ-NA2 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Wavelength: 1310nm (infrared transmission band)
• Connector Type: LC (optical interface standard)
• Mounting Type: Pluggable SFP+ or SFP28 form factor
• Voltage Supply Range: Compatible with 3.3V nominal operation
• Applications: Ethernet or General Purpose transceiver functionality

Identified Substitutes:

1. AFCT-739DMZ-NA2-C (ATGBICS): Direct form-factor equivalent with matching SFP+ mounting, LC connector, 1310nm wavelength, and 10Gbps data rate capability. Product Status: Active.

2. AFCT-725SMZ (Broadcom Limited): Alternative wavelength-matched transceiver with 1310nm operation and LC connector. Operates at higher data rate (25Gbps) with SFP28 form factor. Product Status: Last Time Buy.

Parameter Comparison

Engineering Selection Recommendations

AFCT-739DMZ-NA2-C (ATGBICS): This substitute is the primary equivalent for direct replacement. It maintains identical form factor (SFP+), connector type (LC), wavelength (1310nm), and comparable data rate (10Gbps). The part is classified as Active, ensuring current availability and ongoing support. RoHS Compliance and EAR99 ECCN classification are provided. This substitute is suitable for applications requiring direct mechanical and electrical compatibility with the original AFCT-739DMZ-NA2.

AFCT-725SMZ (Broadcom Limited): This substitute shares the same manufacturer as the original part and maintains wavelength compatibility (1310nm) and LC connector type. However, it operates at a higher data rate (25Gbps) and uses the SFP28 form factor rather than SFP+. This part is classified as Last Time Buy, indicating limited future availability. Selection of this substitute requires confirmation that the host equipment supports SFP28 form factor and can operate at 25Gbps data rates. RoHS3 Compliance and MSL Level 1 are documented.

Frequently Asked Questions (FAQ)

Q: Can AFCT-739DMZ-NA2-C be used as a direct replacement for AFCT-739DMZ-NA2?

A: Yes. Both parts share identical form factor (SFP+), connector type (LC), wavelength (1310nm), and compatible voltage supply specifications (3.3V nominal operation). The AFCT-739DMZ-NA2-C is manufactured by ATGBICS and maintains Active product status, making it suitable for direct substitution in Ethernet applications.

Q: What is the key difference between AFCT-739DMZ-NA2-C and AFCT-725SMZ?

A: The primary differences are form factor and data rate. AFCT-739DMZ-NA2-C uses SFP+ form factor with 10Gbps capability, while AFCT-725SMZ uses SFP28 form factor with 25Gbps capability. Both maintain 1310nm wavelength and LC connector compatibility. Equipment compatibility must be verified before selecting AFCT-725SMZ.

Q: Why is the original AFCT-739DMZ-NA2 classified as Obsolete?

A: Obsolete classification indicates the part is no longer manufactured or supported by Broadcom Limited. Substitute parts must be identified for ongoing system maintenance and component replacement requirements.

Q: Are there voltage supply compatibility concerns when substituting these parts?

A: The original AFCT-739DMZ-NA2 operates within 3.135V to 3.465V range. Both substitutes operate at 3.3V nominal supply voltage, which falls within the original specification range. Voltage supply compatibility is maintained across all three parts.

Q: What compliance certifications are provided for the substitute parts?

A: AFCT-739DMZ-NA2-C is RoHS Compliant with EAR99 ECCN classification and REACH Unaffected status. AFCT-725SMZ is RoHS3 Compliant with ECCN 5A991B5A classification and MSL Level 1 rating. Both substitutes meet current regulatory requirements.

Q: Can AFCT-725SMZ be used in equipment designed for SFP+ modules?

A: No. AFCT-725SMZ uses SFP28 form factor, which is physically and electrically distinct from SFP+ form factor. Equipment must have SFP28 slots and support 25Gbps operation. Physical form factor compatibility must be confirmed before selection.
