Telecom Procurement Notes

This component is officially marked as obsolete or discontinued by the manufacturer. Availability is restricted, and it may not be sold in all regions through standard distributors. Verification of current stock status and end-of-life documentation is required before procurement planning. Sourcing should focus on authorized surplus channels or verified legacy inventory providers.

Telecom Selection Notes

Engineers replacing this part must account for its discontinued status. The MT8985AL is a related variant but lacks lead-free certification, whereas the AL1 suffix indicates Pb Free compliance. Selection of alternative components requires matching the 44-MQFP footprint, 4.75V-5.25V supply requirements, and -40°C to +85°C temperature range. Functional equivalence in digital bus switching must be validated against specific application timing constraints.

Telecom Part Context

The MT8985AL1 belongs to the Microchip Technology digital bus switch family. It is categorized under Switch ICs and specifically Digital Bus Switch ICs. This series includes variants like the MT8986AL1 and MT8981DP1, which share similar interface roles but differ in packaging and specific switching rates. The AL1 designation distinguishes it from older non-lead-free versions like the MT8985AL.

Telecom Replacement Considerations

The MT8985AL is a direct pin-compatible variant but is not RoHS compliant. Other Microchip switches like the MT8986AL1 offer multi-rate switching but require verification of package compatibility. No other public substitute part numbers are confirmed.
