Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPF2416T is determined by compatibility across the following critical parameters:

• Data Rate Capability: The substitute must support the required 155Mbps operational speed or higher
• Supply Voltage: The substitute must operate within or be compatible with the 4.75V to 5.25V supply range
• Minimum Receivable Power: The substitute must achieve sensitivity equal to or better than -43dBm
• Supply Current: The substitute current consumption must be evaluated for system power budget compatibility
• Compliance Standards: RoHS3 compliance and REACH unaffected status ensure regulatory alignment

The HFBR-2416TZ from Broadcom Limited is identified as a manufacturer-recommended substitute based on functional equivalence within the fiber optic receiver category.

Parameter Comparison

Engineering Selection Recommendations

The HFBR-2416TZ qualifies as a functional substitute based on the following criteria:

• Active Product Status: The HFBR-2416TZ maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete OPF2416T
• Data Rate Compatibility: The 160MBd capability of the HFBR-2416TZ exceeds the 155Mbps requirement, providing operational margin
• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements
• Moisture Sensitivity: Identical MSL rating of 1 (Unlimited) ensures equivalent handling and storage requirements

Critical Design Consideration: The HFBR-2416TZ operates at 1.84V supply voltage and draws 100 mA, representing significant differences from the OPF2416T specifications (4.75V-5.25V supply, 15 mA). System-level voltage regulation and power delivery architecture must be evaluated and modified to accommodate these electrical parameter differences.

Frequently Asked Questions (FAQ)

Q: Can the HFBR-2416TZ directly replace the OPF2416T without circuit modifications?

A: No. While both components function as fiber optic receivers with compatible data rates, the HFBR-2416TZ requires a different supply voltage (1.84V versus 4.75V-5.25V) and draws significantly higher current (100 mA versus 15 mA). Circuit redesign is necessary to accommodate these electrical differences.

Q: What is the primary reason for seeking a substitute for the OPF2416T?

A: The OPF2416T is classified as obsolete. The HFBR-2416TZ is an active product from a major manufacturer, ensuring continued availability and supply chain reliability.

Q: Are there packaging differences between these components?

A: The OPF2416T packaging information is not specified in the available data. The HFBR-2416TZ is supplied in Tube packaging. Physical form factor compatibility must be verified during integration.

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

A: Yes. Both the OPF2416T and HFBR-2416TZ are ROHS3 compliant, REACH unaffected, and share identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited).

Q: What is the data rate relationship between these components?

A: The OPF2416T operates at 155Mbps, while the HFBR-2416TZ operates at 160MBd. The substitute provides higher data rate capability, ensuring compatibility with the original specification.
