Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-79EEPZ is determined by the following critical parameters:

• Wavelength: 850nm (mandatory match)
• Connector Type: MTP® (MPO) or MPO (functionally compatible)
• Mounting Type: Pluggable, QSFP+ or QSFP (form factor compatibility)
• Voltage - Supply: 3.3V (mandatory match)
• Application: Ethernet (mandatory match)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The AFBR-79EEPZ-C qualifies as a substitute based on matching wavelength (850nm), connector type (MPO), mounting type (Pluggable, QSFP), supply voltage (3.3V), Ethernet application, and ROHS3 compliance. The data rate difference (40Gbps vs. 10.3125Gbps) reflects enhanced performance capability while maintaining backward compatibility with the electrical and mechanical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The AFBR-79EEPZ-C is available as an active product with current manufacturing support, whereas the AFBR-79EEPZ is obsolete. Both modules meet ROHS3 compliance requirements and share identical electrical specifications (3.3V supply, 850nm wavelength, Ethernet application). The AFBR-79EEPZ-C provides enhanced data rate capability (40Gbps vs. 10.3125Gbps) while maintaining mechanical and electrical interface compatibility through matching MPO connector configuration and QSFP form factor. Selection of the substitute should be based on system architecture requirements and equipment compatibility verification.

Frequently Asked Questions (FAQ)

Q: Can the AFBR-79EEPZ-C directly replace the AFBR-79EEPZ in existing systems?

A: The AFBR-79EEPZ-C shares the same wavelength (850nm), connector type (MPO), supply voltage (3.3V), and Ethernet application as the AFBR-79EEPZ. Both modules are ROHS3 compliant and use compatible QSFP form factors. Physical and electrical interface compatibility is established. System-level compatibility depends on equipment specifications and operational requirements.

Q: What is the significance of the data rate difference between these modules?

A: The AFBR-79EEPZ operates at 10.3125Gbps per lane, while the AFBR-79EEPZ-C operates at 40Gbps. This represents enhanced performance capability in the substitute module. The higher data rate does not affect mechanical or basic electrical interface compatibility, as both modules maintain identical supply voltage, wavelength, and connector specifications.

Q: Why is the AFBR-79EEPZ classified as obsolete?

A: Product obsolescence indicates that the AFBR-79EEPZ is no longer in active production by Broadcom Limited. The AFBR-79EEPZ-C, manufactured by ATGBICS, is classified as active and represents a currently available alternative for procurement and system deployment.

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

A: Both the AFBR-79EEPZ and AFBR-79EEPZ-C are ROHS3 compliant. The AFBR-79EEPZ-C includes REACH Unaffected status. Both modules meet applicable regulatory requirements for electronic component deployment.

Q: What role does the MTP® (MPO) connector specification play in substitution?

A: The MTP® (MPO) connector type is a critical parameter for substitution eligibility. Both modules use MPO-based connectors, ensuring mechanical compatibility with existing fiber optic infrastructure and equipment interfaces designed for this connector standard.
