JST PH is a 2.0 mm pitch single-row wire-to-board connector system.
It is designed to meet the demand for high-density connection of internal wires to printed circuit boards. It is compact, highly reliable and low in cost.
JST SH is a 1.0 mm pitch sing-row wire-to-board connector system. It is compact and low-profile.

Pitch size is a primary distinguishing factor between JST PH and JST SH connectors. JST PH connectors is 2.0mm (0.079 inches) pitch, while JST SH is 1.0mm (0.039 inches) pitch. This means that JST SH connectors have a higher pin density and are suitable for use in smaller form factor devices.
JST PH connectors are available in circuit sizes ranging from 2 to 16 contacts, whereas JST SH connectors can have anywhere from 2 to 15 contacts, and 20 contacts.
Current rating of JST PH connector is 2A per contact, and the voltage rating is 100V AC/DC. Making it suitable for use in applications with higher power requirements. Correspondingly, JST SH connector is 1A, and 50V AC/DC. Which is suitable for low-power applications.
JST PH connectors are available in both SMT and through-hole types, making them well-suited to a variety of applications. While JST SH connectors have only SMT type, which limits their use in through-hole PCB designs. However, JST SH connectors’ smaller pitch size makes them ideal for use in high-density PCB designs that require small and compact connectors.
JST PH connectors feature a friction lock mechanism, which helps to keep the connection between female and male secure and stable. This makes them ideal for applications where vibration or other external factors could potentially cause the connection to become loose.
