Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-5715APZ-CS1 are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Data Rate: 1.25Gbps (Gigabit Ethernet standard)
• Mounting Type: Pluggable, SFP form factor
• Voltage Supply Range: 3.3V nominal operation
• Wavelength: 1310nm (long-wavelength, single-mode operation)
• RoHS Compliance: ROHS3 Compliant

Substitution Logic: The AFCT-5715APZ-CS1 operates at 1.25Gbps with SFP form factor. Substitute parts must maintain the same data rate and pluggable SFP mounting configuration to ensure compatibility with existing host equipment. Voltage supply specifications must fall within acceptable operating ranges for the host system. Wavelength and connector type variations indicate different physical and optical interfaces that may require system-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

AFCT-5715APZ-CS1-C (ATGBICS): This substitute maintains the primary electrical specification of 1.25Gbps data rate and operates at 3.3V supply voltage, which falls within the acceptable range of the main part. The component is classified as Active product status, ensuring continued availability and supply chain stability. RoHS compliance is confirmed. The primary difference is the connector type (LC Duplex versus RJ45) and the explicit wavelength specification of 1310nm. This part is suitable for applications where the host system supports LC Duplex optical connectors and SFP form factor modules.

AFCT-725SMZ (Broadcom Limited): This substitute is manufactured by the original equipment manufacturer (Broadcom Limited) and maintains ROHS3 compliance. However, this part operates at 25Gbps data rate, which represents a significant increase from the 1.25Gbps specification of the main part. The mounting type is SFP28 rather than SFP, indicating a different physical form factor. This part is classified as Last Time Buy status. Selection of this substitute requires confirmation that the host system supports both the higher data rate and the SFP28 form factor, as these represent material differences from the original specification.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-5715APZ-CS1-C be used as a direct replacement for the AFCT-5715APZ-CS1?

A: The AFCT-5715APZ-CS1-C shares the same 1.25Gbps data rate and SFP mounting type. However, the connector type differs (LC Duplex versus RJ45). Direct replacement is possible only if the host system supports LC Duplex optical connectors. Mechanical and optical interface compatibility must be confirmed before deployment.

Q: What is the significance of the AFCT-725SMZ having a 25Gbps data rate?

A: The AFCT-725SMZ operates at 25Gbps, which is 20 times faster than the 1.25Gbps specification of the main part. Additionally, this part uses the SFP28 form factor rather than SFP. These differences indicate that the AFCT-725SMZ is designed for higher-speed applications and requires host equipment specifically rated for SFP28 modules and 25Gbps operation. This part is not a direct functional equivalent.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part AFCT-5715APZ-CS1 is ROHS3 Compliant. The substitute AFCT-5715APZ-CS1-C is RoHS Compliant, and the substitute AFCT-725SMZ is ROHS3 Compliant. All parts meet regulatory environmental requirements.

Q: What does "Obsolete" product status mean for the main part?

A: Obsolete status indicates that the AFCT-5715APZ-CS1 is no longer manufactured and is not available for new orders from the manufacturer. Existing inventory may be available through authorized distributors, but long-term supply cannot be assured. Substitute parts with Active or Last Time Buy status provide alternative sourcing options.

Q: How do voltage specifications affect substitution?

A: The main part operates at 3.135V to 3.465V. Both substitute parts operate at 3.3V nominal voltage, which falls within the acceptable range of the main part. Voltage compatibility is confirmed for both substitutes, provided the host system power supply can deliver the required voltage and current specifications.

Q: What is the difference between SFP and SFP28 form factors?

A: SFP (Small Form-factor Pluggable) and SFP28 are different physical form factors. SFP modules are smaller and designed for lower data rates (up to 10Gbps typical). SFP28 modules are physically larger and designed for higher data rates (up to 28Gbps). These form factors are not mechanically interchangeable. Host equipment must be specifically designed to accept the form factor of the transceiver module being installed.

Q: Can the AFCT-725SMZ be used in equipment designed for the AFCT-5715APZ-CS1?

A: No. The AFCT-725SMZ uses the SFP28 form factor, while the main part uses SFP form factor. These are not mechanically compatible. Additionally, the 25Gbps data rate of the AFCT-725SMZ exceeds the 1.25Gbps capability of equipment designed for the main part. Physical and electrical incompatibility prevents this substitution.
