Dell OptiPlex 3020, 7020, 3040, 3050 & 7040 Spare Parts Cross-Reference Guide

The Dell OptiPlex 3020, 7020 and 9020, and the 3040, 5040, 7040, 3050, 5050 and 7050 that followed them, are still the everyday desktop in many offices. Small parts such as SATA cables, power button cables and drive caddies are often missing or damaged when a machine is refurbished, and Dell part numbers are the only reliable way to match them.

This page cross-references the spares we hold for these models as physical stock at our warehouse in Pentre, South Wales, including the 3030, 3050 and 3240 all-in-one models. Use Ctrl+F to search for the number printed on your part.

How to find your Dell part number

  • Dell part number: Dell parts carry a five-character code such as 4YP6J, usually on a white barcode label after the letters DP/N.
  • Leading zero: the label normally shows the code with a zero in front, such as 04YP6J. Search this page without the zero.
  • Check the case size: these models came as a mini tower (MT), small form factor (SFF), Micro and all-in-one (AIO). Most parts fit only one case size, so check the Fits column.

For older models, see the OptiPlex 390, 790, 990, 3010, 7010 and 9010 guide.
