JST PH vs JST XH family

Manufacturer nominal pitches differ (2.0 mm PH and 2.5 mm XH). Similar white housings are not interchangeable by eye; verify exact part-code pairs.

How they differ

JST PH wire-to-board connector family Find a stamped or documented part number on the housing or PCB design; compare family series, circuit count, header style and mating direction.
JST XH wire-to-board connector family Search the maker’s part number (for example an XHP housing series) and verify the shroud, mating direction and position count.

JST SH vs JST GH familySH is nominal 1.0 mm and friction-lock; GH is nominal 1.25 mm with a secure-lock design. Mating still depends on the exact housing and header.BNC vs TNC coaxial connectorsBNC uses bayonet coupling while TNC uses threaded coupling. Connector family, impedance and application still need to be verified independently.DisplayPort connector vs DisplayPort 2.1The full-size DisplayPort connector does not identify the implemented DisplayPort generation, link rate or optional features.DisplayPort vs Mini DisplayPortFull-size DisplayPort and Mini DisplayPort are different physical forms. Mini DisplayPort shape also appeared on Thunderbolt 1/2 products, so function still needs device evidence.DVI-D dual-link vs DVI-I dual-linkDVI-D and DVI-I use related shells but have different contact arrangements. The analog-contact area is a key physical distinction.DVI-D single-link vs DVI-D dual-linkBoth are DVI-D forms, but their contact patterns differ. Inspect the complete pin field instead of relying on the DVI label alone.
