Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the AFBR-79EEPZ-CS3 is based on the following critical parameters that determine functional compatibility:

Common Parameters:

• Wavelength: 850 nm (multimode fiber standard)
• Connector Type: MTP/MPO (optical interface standard)
• Application Category: Fiber optic transceiver modules

Divergent Parameters:

• Data Rate: Main part operates at 10.3125 Gbps; substitute operates at 40 Gbps
• Supply Voltage: Main part requires 3.135V ~ 3.465V; substitute requires 5V
• Mounting Type: Main part uses panel mount, snap-in; substitute uses pluggable, QSFP+ form factor
• Product Status: Main part is obsolete; substitute is active

The identified substitute part AFBR-79EEPZ-CS3-C shares the 850nm wavelength and MTP/MPO connector standard but operates at a higher data rate with different electrical and mechanical specifications. This represents a performance-class upgrade rather than a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The AFBR-79EEPZ-CS3 is classified as obsolete. The substitute part AFBR-79EEPZ-CS3-C carries active product status, indicating ongoing manufacturer support and availability.

Compliance and Certification: The substitute part AFBR-79EEPZ-CS3-C is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory standards. The main part specifications do not include these compliance certifications.

Export Classification: The substitute part is classified under ECCN EAR99, indicating standard commercial classification. The main part carries an obsolete designation.

Functional Compatibility: Selection between these parts depends on system requirements. The substitute operates at 40 Gbps compared to the main part's 10.3125 Gbps, requiring different host interface support. The substitute requires 5V supply voltage versus the main part's 3.135V ~ 3.465V range. The substitute uses QSFP+ pluggable form factor versus the main part's panel mount, snap-in configuration. These differences necessitate system-level evaluation before substitution.

Frequently Asked Questions (FAQ)

Q: Can the AFBR-79EEPZ-CS3-C directly replace the AFBR-79EEPZ-CS3?

A: Direct replacement is not possible without system modifications. The substitute part operates at 40 Gbps versus 10.3125 Gbps, requires 5V supply versus 3.135V ~ 3.465V, and uses QSFP+ pluggable mounting versus panel mount, snap-in configuration. Host equipment must support these specifications.

Q: What wavelength compatibility exists between these parts?

A: Both parts operate at 850nm wavelength, which is the standard multimode fiber wavelength. This represents a common optical interface parameter.

Q: Are the connector types compatible?

A: Both parts use MTP/MPO connector standards. However, the main part is configured for panel mount, snap-in installation, while the substitute uses pluggable QSFP+ form factor. Physical installation methods differ.

Q: What is the significance of the obsolete status?

A: The AFBR-79EEPZ-CS3 is no longer manufactured by Broadcom Limited. The substitute part AFBR-79EEPZ-CS3-C is actively produced, ensuring ongoing availability and manufacturer support.

Q: Does the substitute part meet current environmental standards?

A: Yes. The AFBR-79EEPZ-CS3-C is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. Compliance status for the main part is not specified.

Q: What are the key electrical differences?

A: The main part requires 3.135V ~ 3.465V supply voltage, while the substitute requires 5V. System power delivery infrastructure must accommodate the substitute's voltage requirement.

Q: How do the data rates affect substitution decisions?

A: The substitute operates at 40 Gbps, which is four times the main part's 10.3125 Gbps rate. Host interface equipment must support 40 Gbps operation. The higher data rate does not provide backward compatibility with 10.3125 Gbps systems.
