AFBR-735ASMZ Equivalent & Substitute Parts

Part Overview

The AFBR-735ASMZ is a SFP28 transceiver module manufactured by Broadcom Limited, designed for Fibre Channel Links applications. This pluggable optical module operates at 25.78125 Gbps with 850nm wavelength and supports LC Duplex connectivity. The module is currently in Last Time Buy status, indicating that original inventory is limited and alternative components may be required for ongoing system deployments and maintenance.

Identification of equivalent and substitute parts is necessary to ensure continued availability, support system redundancy, and maintain operational flexibility across compatible network infrastructure.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFBR-735ASMZ is determined by alignment of the following critical parameters:

Primary Substitution Criteria:

• Data Rate: 25 Gbps or higher (25.78125 Gbps nominal)
• Wavelength: 850 nm (multimode, short-wavelength)
• Connector Type: LC Duplex
• Voltage Supply Range: Overlapping operational range (3.1V – 3.5V)
• Mounting Type: Pluggable form factor (SFP28 or SFP+ compatible)
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The FTLF8536P5BCL from Coherent meets these substitution criteria through equivalent electrical specifications, identical wavelength and connector configuration, and compatible voltage supply parameters. Both modules support 850 nm multimode transmission with LC Duplex interfaces and operate within overlapping supply voltage ranges.

Engineering Selection Recommendations

AFBR-735ASMZ (Primary Component)

The AFBR-735ASMZ remains the specified component for Fibre Channel Links applications. ROHS3 compliance and active inventory support direct replacement scenarios. Last Time Buy status indicates limited future availability; procurement planning should account for extended lead times or component obsolescence.

FTLF8536P5BCL (Substitute Component)

The FTLF8536P5BCL from Coherent is electrically and mechanically compatible for substitution in systems supporting 25 Gbps multimode optical transmission at 850 nm. Active product status ensures ongoing availability. The component operates within the voltage supply range of the primary part (3.15V – 3.46V overlaps 3.1V – 3.5V). Substitution is applicable in Ethernet-based deployments or systems with protocol flexibility. RoHS compliance status for the substitute part is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can the FTLF8536P5BCL directly replace the AFBR-735ASMZ in all applications?

A: The FTLF8536P5BCL is electrically and mechanically compatible for multimode 850 nm transmission at 25 Gbps. However, the primary part is specified for Fibre Channel Links while the substitute is rated for Ethernet. System compatibility depends on protocol support and host interface capabilities. Connector type (LC Duplex) and mounting form factor (pluggable) are identical.

Q: What is the difference between SFP28 and SFP+ mounting types?

A: SFP28 and SFP+ are both pluggable form factors with LC Duplex connectors. SFP28 is optimized for higher data rates (25 Gbps and above), while SFP+ supports up to 10 Gbps. Both are mechanically compatible in many host systems, though host port specifications determine actual interoperability.

Q: Are the voltage supply ranges compatible?

A: The AFBR-735ASMZ operates at 3.1V – 3.5V, while the FTLF8536P5BCL operates at 3.15V – 3.46V. The ranges overlap from 3.15V to 3.46V, ensuring compatibility within the shared operational window. Host power supply specifications must support both ranges for seamless substitution.

Q: What does Last Time Buy status mean for the AFBR-735ASMZ?

A: Last Time Buy indicates that the manufacturer has announced end-of-life for this component. Existing inventory is available, but future production is discontinued. Organizations should evaluate substitute components and plan procurement accordingly to avoid supply disruptions.

Q: Is RoHS compliance verified for the FTLF8536P5BCL?

A: RoHS compliance status for the FTLF8536P5BCL is not specified in the provided documentation. Organizations requiring ROHS3 certification should verify compliance directly with Coherent or through component datasheets before substitution in regulated applications.

Q: What is Moisture Sensitivity Level 1?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. Both the primary part and substitute part carry this rating, eliminating moisture-related handling constraints during storage and installation.
