AFBR-79EADZ Equivalent & Substitute Parts

Part Overview

The AFBR-79EADZ is a 40Gbps transceiver module operating at 850nm wavelength with 3.3V supply voltage and MTP® (MPO) connector configuration in a pluggable QSFP+ form factor. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system design and procurement planning. Substitute parts must maintain electrical compatibility across data rate, wavelength, voltage supply, and connector specifications to ensure seamless integration into existing or legacy system architectures.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-79EADZ is determined by strict alignment across the following critical parameters:

• Data Rate: 40Gbps (40Gbe/40GBASE-SR4)
• Wavelength: 850nm (multimode fiber)
• Voltage Supply: 3.3V
• Connector Type: MTP® (MPO) or equivalent MPO configuration
• Mounting Type: Pluggable QSFP+ form factor
• RoHS Compliance: ROHS3 Compliant

The substitute part AFBR-79EADZ-C meets all critical electrical and mechanical parameters required for functional equivalence. Both parts operate at identical data rates, wavelengths, and supply voltages with compatible connector and mounting specifications.

Parameter Comparison

Engineering Selection Recommendations

The AFBR-79EADZ-C serves as a direct functional equivalent for the obsolete AFBR-79EADZ. Both components satisfy identical electrical specifications (40Gbps, 850nm, 3.3V) and mechanical requirements (MPO connector, QSFP+ pluggable form factor). The substitute part maintains ROHS3 compliance, ensuring regulatory alignment with the original component.

Selection of AFBR-79EADZ-C is supported by its active product status, providing assured availability and ongoing manufacturer support compared to the obsolete original part. Electrical and mechanical compatibility is confirmed across all critical parameters specified for this transceiver category.

Frequently Asked Questions (FAQ)

Q: Can AFBR-79EADZ-C be used as a direct replacement for AFBR-79EADZ?

A: Yes. Both components operate at 40Gbps, 850nm wavelength, with 3.3V supply voltage and MPO connector configuration in QSFP+ form factor. Electrical and mechanical specifications are equivalent.

Q: What is the primary reason for seeking a substitute?

A: The AFBR-79EADZ is classified as obsolete. The AFBR-79EADZ-C maintains active product status, ensuring component availability and manufacturer support.

Q: Are there connector compatibility considerations?

A: Both parts use MTP® (MPO) connectors in QSFP+ pluggable configuration. Connector compatibility is maintained between the original and substitute part.

Q: Does RoHS compliance differ between the parts?

A: No. Both the AFBR-79EADZ and AFBR-79EADZ-C are ROHS3 compliant, maintaining regulatory alignment.

Q: What packaging differences exist?
