Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPF2418T fiber optic receiver is based on the following critical parameters:

• Data Rate Compatibility: The substitute must support the required signaling speed for the application.
• Supply Voltage Range: The substitute must operate within or be compatible with the system's power supply specifications.
• Minimum Receivable Power: The substitute must meet or exceed the sensitivity requirements for the optical signal detection.
• Supply Current: The substitute's current draw must be compatible with the system's power budget.
• Regulatory Compliance: Both RoHS3 and REACH compliance ensure environmental and safety standards are maintained.
• Moisture Sensitivity Level: MSL rating ensures proper handling and storage requirements are met.

The HFBR-2416TZ from Broadcom Limited is identified as a substitute based on its classification as an active fiber optic receiver product with comparable functional characteristics for general-purpose optical communication applications.

Parameter Comparison

Engineering Selection Recommendations

The HFBR-2416TZ is an active product from Broadcom Limited and maintains full compliance with ROHS3 and REACH regulatory requirements, matching the environmental standards of the OPF2418T. Both devices carry MSL rating 1, indicating identical moisture sensitivity handling requirements.

The HFBR-2416TZ is suitable for applications where the specified electrical parameters—including the lower supply voltage of 1.84V, reduced data rate of 160 MBd, and higher supply current of 100 mA—are compatible with system design constraints. The active product status of the HFBR-2416TZ ensures ongoing availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: What are the primary differences between the OPF2418T and HFBR-2416TZ?

A: The OPF2418T operates at 194 Mbps with a supply voltage range of 4.75V to 5.25V and draws 15 mA. The HFBR-2416TZ operates at 160 MBd with a supply voltage of 1.84V and draws 100 mA. Both devices maintain identical RoHS3 and REACH compliance and MSL rating 1.

Q: Can the HFBR-2416TZ directly replace the OPF2418T in existing designs?

A: Direct replacement requires verification that the system design accommodates the HFBR-2416TZ's lower supply voltage (1.84V versus 4.75V–5.25V), lower data rate (160 MBd versus 194 Mbps), and higher supply current (100 mA versus 15 mA).

Q: Are there packaging considerations when substituting these parts?

A: The OPF2418T packaging is not specified in the available data. The HFBR-2416TZ is supplied in Tube packaging. Verify mechanical compatibility and PCB footprint requirements for your application.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the OPF2418T and HFBR-2416TZ are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited), ensuring equivalent environmental and safety compliance.

Q: Why is the OPF2418T classified as obsolete?

A: The OPF2418T is no longer manufactured by TT Electronics/Optek Technology. The HFBR-2416TZ, as an active product from Broadcom Limited, represents a current alternative for fiber optic receiver applications.
