Alcatel 90-0035-01-03-DEPMA7U6AA Expander Card

Alcatel 90-0035-01-03-DEPMA7U6AA Expander Card is a Newbridge/Alcatel 3600-series expansion module used to extend the capacity of the 3600 MainStreet system. Commonly cataloged as Expander Card (6+6), this variant appears as 90-0035-01-03-B with internal code DEPMA7U6AA, and is documented alongside related revisions such as 90-0035-01-03-C. The 90-0035-01 family demonstrates a line of expansion options within the Newbridge 3600 ecosystem, with other variants noted in catalogs, including 90-0035-03 (8+8) and 90-0035-05 (16+). These entries show a consistent approach to increasing the platform’s expansion capacity rather than replacing base equipment. The part is primarily used in legacy telecom and data-network deployments that rely on the 3600 MainStreet platform, where technicians install or replace expander cards to maintain or scale operation of older Newbridge hardware. Internal codes, such as DEPMA7U6AA, help identify the exact revision across disparate listings and catalogs that reference the same 90-0035-01 expander family. Because these are legacy components, they are commonly found in refurbished or used inventories across specialist distributors.
