SMP Plug, Male Pin — 73415 Series, Smooth Bore
The 0734153811: It uses a snap-on fastening mechanism and features a smooth bore interface, which distinguishes it from the full-detent SMP variants that require higher insertion force and a specialized tool for release. This connector is terminated by soldering the contact and the shield, and the mounting pads accept both surface-mount and through-hole soldering — a dual-landing footprint that gives the board designer flexibility when the assembly line runs mixed reflow and wave processes.
Smooth Bore vs. Full Detent — What the Interface Means
The SMP interface comes in three common variants: smooth bore, limited detent, and full detent. That makes it the right choice for board-to-board or cable-to-board connections where the connector pair will be unmated in the field without a special extraction tool. The trade-off is lower axial retention compared to the full-detent version, so if the assembly sees vibration or the cable gets tugged, the smooth bore pair can separate. For those applications, the 73416 series (full detent) is the alternative.
The connector mounts using either surface-mount or through-hole pads, with the shield termination and the centre contact both soldered. The dual-landing pattern means the same PCB footprint works for both processes — useful when a prototype run uses hand-soldered through-hole and production shifts to reflow. The snap-on fastening locks the mated pair without threads or bayonet hardware, so the engagement is quick and the tactile click confirms the mate. Packaging is a bag, which is typical for low-to-moderate volume builds.
