Telecom Procurement Notes

This component is officially obsolete and no longer manufactured by Microchip Technology, with an End of Life date recorded as March 7, 2016. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary markets. Buyers must confirm that the specific lot meets RoHS3 compliance standards. Due to the discontinued status, lead times may vary significantly, and availability is limited to existing inventory rather than new production runs.

Telecom Selection Notes

Given the obsolete status of the LE9500DBJCT, selection requires careful evaluation of long-term supply chain risks. Designers should consider the availability of substitute components, such as the LE9541CUQCT, which is listed as a similar alternative from the same manufacturer. Compatibility checks regarding pinout, electrical parameters, and package dimensions are essential when transitioning to replacement parts to ensure seamless integration into existing telecom interface designs without hardware modifications.

Telecom Part Context

The LE9500DBJCT belongs to the family of telecom interface ICs produced by Microchip Technology, specifically tailored for user line interface concepts. It shares the 28-PLCC packaging format with related models like the LE9500CBJCT. As a discontinued product, it represents a legacy solution for telecom applications, having been succeeded by newer generations of interface controllers within the manufacturer's portfolio that offer updated features and continued manufacturing support.

Telecom Replacement Considerations

The LE9541CUQCT is identified as a similar substitute part number from Microchip Technology. Verification of functional equivalence and pin compatibility is required before adoption.
