Telecom Procurement Notes

This component is officially classified as Obsolete by the manufacturer. Procurement should focus on verifying the authenticity of existing stock or surplus inventory from authorized distributors. Ensure that any available units match the specific SOP24 package style and Harris Corporation origin to avoid counterfeit replacements. Check for compatibility with legacy systems requiring this specific obsolete part number.

Telecom Selection Notes

Selection is limited due to the obsolete status of the HC9P5502B-9. Designers must evaluate end-of-life implications for long-term support. If new designs are required, consider modern SLIC alternatives from current manufacturers. For maintenance of existing equipment, verify that the -42V to -58V supply range and single-circuit capacity meet the system requirements before sourcing obsolete inventory.

Telecom Part Context

The HC9P5502B-9 belongs to the Harris Corporation telecommunications component family, specifically within the Subscriber Line Interface Concept (SLIC) category. It was designed for analog telephony applications, handling line signaling and power feeding functions. The device utilizes a 24-pin Small Outline Package, suitable for automated surface mount assembly processes common in telecom equipment manufacturing during its production lifecycle.

Telecom Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements are not explicitly documented. Engineers must perform functional equivalence analysis when selecting alternative SLIC devices from other manufacturers.
