When searching for JST connectors, you might spot the similarities between their SPHD-001T-P0.5 and the similarly named SPH-001T-P0.5L. Are these interchangeable? What do the ‘D’ and ‘L’ letters call out?
While these two are close, they are not interchangeable. The ‘D’ indicates the contact is used in JST’s PHD connector series, while the non-‘D’ part is for the similar but not compatible PH series.
The ‘L’ suffix is a JST internal callout, with no impact on the product itself.
