Substitute Part Grouping Explanation

Substitution of the MAX1776EUA-T is determined by strict equivalence across the following critical parameters:

  • Input voltage range: 4.5V to 24V
  • Output voltage capability: 1.25V to 24V adjustable/fixed
  • Output current: 600mA
  • Switching frequency: 200kHz
  • Topology: Buck (step-down)
  • Output configuration: Single positive output
  • Package: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)
  • Mounting: Surface mount
  • Operating temperature range: -40°C to 85°C

The substitute part must match all electrical specifications and physical package requirements to ensure functional and mechanical compatibility without circuit redesign.

Engineering Selection Recommendations

The MAX1776EUA+T is a direct substitute for the MAX1776EUA-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications and package configurations. The primary distinction is product status: the MAX1776EUA-T is obsolete, while the MAX1776EUA+T is active and currently in production.

For new designs or system updates requiring the MAX1776 buck regulator functionality, the MAX1776EUA+T is the appropriate selection due to its active status and ongoing availability. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The packaging difference (Cut Tape and Digi-Reel for the substitute) reflects standard distribution formats and does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX1776EUA+T directly replace MAX1776EUA-T without circuit modification?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. Direct substitution is possible without circuit redesign or PCB layout changes.

Q: What is the difference between MAX1776EUA-T and MAX1776EUA+T?

A: The parts are functionally equivalent. The difference lies in product status (obsolete vs. active) and packaging format (standard vs. Cut Tape/Digi-Reel). The electrical specifications and pinout are identical.

Q: Why is MAX1776EUA-T marked as obsolete?

A: Obsolescence indicates the part is no longer in active production. The MAX1776EUA+T represents the current active equivalent from the same manufacturer.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity levels.

Q: What packaging options are available for the substitute part?

A: The MAX1776EUA+T is available in Cut Tape (CT) and Digi-Reel formats, which are standard distribution methods for surface mount components in the 8-uMAX/uSOP package.

Q: Can the MAX1776 be used in applications requiring output currents above 600mA?

A: No. The specified output current rating is 600mA. Applications requiring higher current delivery require alternative regulator ICs with higher current specifications.
