AFBR-79EQDZ Equivalent & Substitute Parts

Part Overview

The AFBR-79EQDZ is a TXRX QSFP 40GBE 4-channel pluggable transceiver module manufactured by Broadcom Limited, designed for general purpose data transmission systems. Operating at 10.312Gbd with 850nm wavelength and 3.3V supply voltage, this module features an MTP® (MPO) connector in a Pluggable-SFF8436 form factor.

The AFBR-79EQDZ is classified as obsolete. Identifying equivalent and substitute parts is essential for system designers and procurement teams requiring continued access to compatible transceiver modules with matching electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

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

• Wavelength: 850nm (multimode, short-reach applications)
• Connector Type: MTP® (MPO) for multi-fiber connectivity
• Mounting Type: Pluggable form factor (QSFP/SFF8436 compatible)
• Voltage Supply: 3.3V operation
• RoHS Compliance: ROHS3 Compliant status

The substitute part AFBR-79EQDZ-C meets these core electrical and mechanical requirements, enabling functional equivalence in systems designed for the original AFBR-79EQDZ module.

Parameter Comparison

Engineering Selection Recommendations

The AFBR-79EQDZ-C qualifies as a substitute based on matching wavelength (850nm), connector type (MPO), mounting type (Pluggable QSFP), and supply voltage (3.3V). Both parts maintain ROHS3 compliance, satisfying regulatory requirements for restricted substance control.

The AFBR-79EQDZ-C carries active product status, ensuring continued availability and manufacturing support, whereas the original AFBR-79EQDZ is obsolete. Selection of the substitute part provides access to a currently manufactured equivalent with established supply chain availability.

Frequently Asked Questions (FAQ)

Q: What makes AFBR-79EQDZ-C a valid substitute for AFBR-79EQDZ?

A: Both parts share identical wavelength (850nm), connector type (MPO), mounting type (Pluggable QSFP), and supply voltage (3.3V). These parameters define mechanical and electrical compatibility in transceiver module applications.

Q: Are there differences in data rate between the main part and substitute?

A: Yes. The AFBR-79EQDZ operates at 10.312Gbd, while the AFBR-79EQDZ-C operates at 40Gbps. Data rate differences do not preclude substitution when the receiving system supports the higher bandwidth capability.

Q: Does the substitute part maintain the same compliance certifications?

A: Both parts are ROHS3 compliant. The original part specifies MSL 1 (Unlimited), while the substitute lists MSL as vendor undefined. Compliance with RoHS requirements is maintained.

Q: What is the primary reason to consider the substitute part?

A: The AFBR-79EQDZ is obsolete. The AFBR-79EQDZ-C is an active product with current manufacturing support and established inventory availability, making it the practical choice for new designs or system replacements.

Q: Are connector types fully compatible between these parts?

A: Both parts use MPO connectors in pluggable QSFP form factors. Mechanical and optical interface compatibility is maintained for standard MTP® (MPO) receptacles.
