D-Sub Receptacle for Standard DB-25 Panel and PCB Mount
The TE Connectivity AMPLIMITE HD-20 207828-3 is a 25-position D-Sub receptacle with female sockets arranged in two rows. It uses the standard DB-25 shell layout (3, DB, B), making it the mating half for any DB-25 male plug in the AMPLIMITE HD-20 series or equivalent industry-standard D-Sub connectors. The vertical orientation and through-hole solder termination suit it for PCB mounting where the connector sits perpendicular to the board, typical for serial/parallel port interfaces, industrial control I/O, and test equipment backplanes.
Mounting and Hardware — No Integral Jackscrews
The shell includes an unthreaded flange feature (Housing/Shell (Unthreaded)), meaning this receptacle ships without jackscrews or threaded inserts. For panel-mount applications requiring mechanical retention and mating-cycle security, the buyer must source separate 4-40 UNC jackscrews and hex nuts — standard D-sub hardware available from TE or third-party suppliers. The through-hole solder tails provide the PCB electrical and mechanical connection; no board locks are present, so the solder joints carry the full insertion and extraction force.
Comparison with Peer Order Codes
The 207828-3 shares the same AMPLIMITE HD-20 series and DB-25 shell layout as the 3-1393480-8 and 8-1437045-3. The primary difference is packaging: the 207828-3 ships in a Tube, while the 3-1393480-8 ships in a Box and the 8-1437045-3 in Bulk. All three are active lifecycle and functionally interchangeable for the same 25-position D-sub receptacle fit — the packaging choice affects tray-fill and pick-and-place handling, not the electrical or mechanical interface.
