AFBR-89BDDZ Equivalent & Substitute Parts

Part Overview

The AFBR-89BDDZ is a QSFP28 transceiver module manufactured by Broadcom Limited, designed for 25.78125Gbps Ethernet applications operating at 850nm wavelength. This pluggable module features LC duplex connectivity and operates within a 3.1V to 3.5V supply voltage range. The part is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts is necessary to ensure continued system availability and support for legacy deployments or to transition to active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-89BDDZ is determined by strict alignment of the following critical parameters:

Form Factor Compatibility: The substitute part must use the QSFP28 pluggable form factor to ensure physical compatibility with existing host equipment slots.

Optical Interface: The substitute part must feature LC duplex connectors to maintain compatibility with installed fiber optic infrastructure.

Voltage Supply Range: The substitute part's supply voltage range must overlap with or be contained within the 3.1V to 3.5V specification to ensure safe operation with existing power delivery systems.

Wavelength Compatibility: The substitute part must support 850nm operation, either as a primary wavelength or within a multi-wavelength specification that includes 850nm.

Protocol and Application: The substitute part must support Ethernet applications to maintain protocol compatibility.

Regulatory Compliance: The substitute part must maintain ROHS3 compliance and MSL 1 rating to meet environmental and handling standards.

The FTLC9152RGPL from Coherent meets these substitution criteria while offering enhanced data rate capability (103.1Gbps) and multi-wavelength support (850nm, 880nm, 910nm, 940nm).

Parameter Comparison

Engineering Selection Recommendations

For Legacy System Maintenance: The AFBR-89BDDZ remains the specified component for systems designed and validated with Broadcom QSFP28 modules. Current inventory of 1073 units supports near-term requirements. Procurement should prioritize existing stock given Last Time Buy status.

For System Transition: The FTLC9152RGPL from Coherent is suitable as a substitute for new deployments or system upgrades. The part is in Active production status, ensuring long-term availability. The FTLC9152RGPL maintains all critical compatibility parameters: QSFP28 form factor, LC duplex connectors, 850nm wavelength support, overlapping voltage supply range, Ethernet protocol support, and ROHS3 compliance with MSL 1 rating.

Compliance Verification: Both parts carry identical ECCN (5A991B1) and HTSUS (8517.62.0090) classifications, confirming regulatory and trade compliance alignment.

Frequently Asked Questions (FAQ)

Q: Can the FTLC9152RGPL directly replace the AFBR-89BDDZ in existing equipment?

A: Physical and electrical compatibility is confirmed. Both parts use the QSFP28 form factor, LC duplex connectors, and operate within compatible voltage supply ranges. The FTLC9152RGPL supports 850nm wavelength operation required by the original specification. Host equipment firmware or driver validation may be required depending on manufacturer implementation.

Q: Why does the FTLC9152RGPL have a higher data rate (103.1Gbps vs. 25.78125Gbps)?

A: The FTLC9152RGPL is a higher-performance module designed for 100G Ethernet applications. When operating at 850nm wavelength, the module is backward compatible with 25.78125Gbps Ethernet systems. The host equipment will negotiate the appropriate data rate based on its capabilities.

Q: Are there voltage supply concerns when substituting these parts?

A: No. The FTLC9152RGPL supply voltage range (3.135V ~ 3.465V) overlaps substantially with the AFBR-89BDDZ range (3.1V ~ 3.5V). Both parts operate safely within standard 3.3V supply systems.

Q: What is the significance of the different product statuses?

A: The AFBR-89BDDZ is in Last Time Buy status, meaning Broadcom has ceased new production and existing inventory will not be replenished. The FTLC9152RGPL is in Active status, indicating Coherent continues manufacturing and will support long-term availability. For new designs or long-term system support, the active product is preferred.

Q: Do both parts meet the same environmental and regulatory standards?

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both share identical ECCN and HTSUS classifications, confirming equivalent regulatory treatment.

Q: Can the FTLC9152RGPL operate at wavelengths other than 850nm?

A: The FTLC9152RGPL supports multiple wavelengths (850nm, 880nm, 910nm, 940nm). However, for substitution purposes, the 850nm wavelength ensures compatibility with existing 850nm infrastructure and systems designed for the AFBR-89BDDZ.
