Key Parameters

Substitute Part Grouping Explanation

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

Core Compatibility Criteria:

• Data Rate: 25Gbps or higher (AFBR-735TMZ operates at 25.78125Gbps)
• Wavelength: 850nm (multimode operation)
• Connector Type: LC Duplex
• Application: Ethernet transceiver
• Supply Voltage: Overlapping or compatible range with 3.1V ~ 3.5V
• Form Factor: Pluggable transceiver module

The FTLF8536P5BCL from Coherent meets these substitution criteria through equivalent electrical performance and mechanical compatibility, despite differences in form factor designation (SFP+ versus SFP28) and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

AFBR-735TMZ (Broadcom Limited):

• Primary selection for existing designs and systems currently specified with this part number
• Last Time Buy status requires forward planning for long-term procurement
• ROHS3 compliant with unlimited moisture sensitivity rating
• Operates within 3.1V to 3.5V supply range

FTLF8536P5BCL (Coherent):

• Active product status provides extended availability and supply chain continuity
• Equivalent electrical performance at 25Gbps data rate with 850nm wavelength
• Supply voltage range of 3.15V to 3.46V overlaps with AFBR-735TMZ operating window
• Identical ECCN and HTSUS classifications support regulatory and compliance alignment
• Form factor difference (SFP+ versus SFP28) requires mechanical compatibility verification with host equipment

Selection between these parts should be based on system form factor requirements, available inventory, and long-term supply chain strategy given the Last Time Buy status of the primary part.

Frequently Asked Questions (FAQ)

Q: Can FTLF8536P5BCL directly replace AFBR-735TMZ in existing systems?

A: Electrical compatibility is established through matching data rate, wavelength, connector type, and overlapping supply voltage ranges. However, the form factor difference between SFP28 and SFP+ requires verification that the host equipment supports both module types. Physical slot compatibility must be confirmed before deployment.

Q: What is the significance of the Last Time Buy status for AFBR-735TMZ?

A: Last Time Buy indicates that Broadcom Limited will discontinue production of this part. Organizations using this component should evaluate substitute options and plan procurement accordingly to avoid supply interruptions.

Q: Are the supply voltage ranges compatible between these two parts?

A: The AFBR-735TMZ operates at 3.1V to 3.5V, while the FTLF8536P5BCL operates at 3.15V to 3.46V. The overlapping range of 3.15V to 3.5V ensures functional compatibility within standard operating conditions.

Q: What is the difference between SFP28 and SFP+ form factors?

A: SFP28 and SFP+ are both small form factor pluggable transceiver modules with LC duplex connectors. The primary difference lies in their mechanical dimensions and host equipment slot specifications. Equipment designed for one form factor may not physically accommodate the other without adapter solutions.

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

A: Both parts share identical ECCN classification (5A991B1) and HTSUS code (8517.62.0090), indicating equivalent regulatory treatment. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What data rate difference exists between these parts?

A: AFBR-735TMZ operates at 25.78125Gbps while FTLF8536P5BCL operates at 25Gbps. The FTLF8536P5BCL data rate is slightly lower but remains within the 25G Ethernet standard specification range and is functionally compatible for 25G applications.
