OPF2418TC Fiber Optic Receiver - Equivalent & Substitute Parts

Part Overview

The OPF2418TC is a fiber optic receiver manufactured by TT Electronics / Optek Technology, designed for general-purpose applications requiring 194 Mbps data rate transmission. This component operates within a 4.75V to 5.25V supply voltage range with a minimum receivable power of -7.6 dBm and a supply current of 15 mA. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OPF2418TC is determined by compatibility across the following critical parameters: data rate capability, supply voltage range, minimum receivable power sensitivity, and regulatory compliance status. The HFBR-2416TCZ from Broadcom Limited is identified as a manufacturer-recommended substitute. While the HFBR-2416TCZ operates at a lower data rate (160 MBd versus 194 Mbps) and requires different supply voltage (1.84V versus 4.75V ~ 5.25V), it maintains equivalent RoHS3 compliance and REACH unaffected status. The reduced data rate and altered voltage requirements represent the primary technical trade-offs in this substitution relationship.

Parameter Comparison

Engineering Selection Recommendations

The HFBR-2416TCZ is an active product with current manufacturing support from Broadcom Limited, providing supply chain continuity for applications transitioning from the obsolete OPF2418TC. Both components maintain identical RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment across substitution. Selection of the HFBR-2416TCZ requires circuit-level accommodation for the reduced data rate specification (160 MBd versus 194 Mbps) and modified supply voltage requirement (1.84V versus 4.75V ~ 5.25V). The increased supply current demand (100 mA versus 15 mA) necessitates power budget reassessment in the target application.

Frequently Asked Questions (FAQ)

Q: Can the HFBR-2416TCZ directly replace the OPF2418TC without circuit modifications?

A: No. The HFBR-2416TCZ requires different supply voltage (1.84V versus 4.75V ~ 5.25V) and operates at a reduced data rate (160 MBd versus 194 Mbps). Circuit redesign is necessary to accommodate these parameter differences.

Q: What is the primary reason for substitution?

A: The OPF2418TC is classified as obsolete. The HFBR-2416TCZ is an active product with ongoing manufacturer support from Broadcom Limited.

Q: Are both components compliant with current environmental regulations?

A: Yes. Both the OPF2418TC and HFBR-2416TCZ maintain ROHS3 compliance and REACH unaffected status.

Q: What is the impact of the data rate difference?

A: The HFBR-2416TCZ operates at 160 MBd compared to the OPF2418TC at 194 Mbps. Applications requiring the full 194 Mbps bandwidth cannot operate at the reduced data rate without system redesign.

Q: How does the supply current difference affect system design?

A: The HFBR-2416TCZ requires 100 mA supply current versus 15 mA for the OPF2418TC. Power supply and thermal management provisions must be reassessed accordingly.
