Telecom Procurement Notes

This component is officially obsolete and no longer manufactured by Microchip Technology. Verification of availability should focus on surplus or secondary market sources rather than direct production channels. Buyers must confirm the authenticity of existing stock due to the long-standing End-of-Life status. Compatibility checks with replacement parts are recommended before procurement decisions are finalized.

Telecom Selection Notes

Designers requiring this specific SLIC function should note that the LE9500CBJC is discontinued. Selection processes must prioritize verified substitute components such as the LE9541CUQCT, which serves as a similar alternative within the manufacturer's portfolio. Engineering reviews should assess pinout compatibility and electrical parameter alignment when transitioning from this obsolete part to ensure system continuity without redesign.

Telecom Part Context

The LE9500CBJC belongs to Microchip Technology's legacy telecommunications interface product line. It was engineered to provide essential subscriber line interface capabilities for voice and data transmission networks. As a specialized SLIC, it facilitated the connection between central office equipment and end-user telephony devices. Its retirement reflects the evolution of telecom interface technologies toward more integrated or digital solutions.

Telecom Replacement Considerations

The LE9541CUQCT is documented as a similar replacement part offered by Microchip Technology.
