HYC9068R

Overview

The HYC9068R is a network interface transceiver manufactured by SMSC. It is classified as a hybrid device containing one transceiver within a single package. The component utilizes ceramic packaging in a SIP20H,1.2 form factor with a 2.54 mm terminal pitch and single-sided terminal placement. It operates at commercial temperature levels ranging from unspecified minimums to a maximum of 70 °C. The unit features tin/lead (Sn/Pb) terminations and does not support surface mount installation. The device is not RoHS compliant and holds an unknown JESD-609 reach compliance code.

Feature Summary

• Integrates a single network transceiver function within a hybrid circuit architecture.
• Constructed using ceramic materials for the package body to ensure structural integrity.
• Designed for through-hole mounting via single-sided terminal positioning.

Applications

• Network interface circuitry requiring hybrid transceiver solutions.
• Telecommunications equipment utilizing commercial-grade components.
• Legacy system integration where SIP20H packages are required.

Procurement Notes

Verify RoHS non-compliance status prior to procurement, as the component is explicitly marked as not qualified for lead-free standards. Confirm the SIP20H,1.2 package dimensions match the target PCB footprint, specifically noting the 2.54 mm pitch. Ensure the supplier provides documentation confirming the ceramic construction and tin/lead termination material to avoid substitution errors with plastic or lead-free variants.

Selection Notes

Select this component only when a hybrid network transceiver with a 20-pin SIP package is strictly required. Consider the 70 °C maximum operating temperature limit against the environmental conditions of the final assembly. Evaluate the compatibility of tin/lead terminations with the soldering process used in the manufacturing line, as surface mount alternatives are not available for this specific part number.

Part Context

The HYC9068R belongs to a family of network interface devices produced by SMSC. It shares core functional descriptions with the HYC9068S, differing primarily in package specifications. While both utilize ceramic bodies and hybrid technology, the HYC9068R is distinguished by its SIP20H,1.2 package code compared to the HYC9068S's SIP20,.4 designation. Both parts operate at commercial temperatures and feature identical terminal counts and materials.

Replacement Considerations

The HYC9068S is a documented similar component with identical functional descriptions and electrical characteristics. However, it utilizes a different package code (SIP20,.4 versus SIP20H,1.2). Verify mechanical fit before substitution, as the package height or pin configuration may differ despite shared internal hybrid technology.
