JST XH connector is a single row 2.50mm pitch (pin spacing), crimp style wire to board connector system. Avaible circcuit size from 1 to 20. There are 4 types of header connectors (straight through-hole, right angle through hole, straight SMT, right angle SMT). Applicable wire size from AWG30 to AWG22. Current rating 3A, current voltage 250V.
The main difference between JST XH and JST PH connector is the pitch size and current rating. JST XH is 2.50 mm pitch, while JST PH is 2.0 mm pitch. The current rating of JST XH is 3A, while JST PH is 2A.
They are both single row wire to board connector system. With 4 types of PCB headers (straight through-hole, right angle through-hole, straight SMT, right angle SMT).
Following is the detailed comparison of the two.

Many people ask “what is the difference between jst xh and xhp?”. But this is not a correct question.
JST XH is the family of the connetor series. While JST XHP is the plug housing (wire connector) of the it. JST XHP is a subset of JST XH.
Resources: JST XH Catalog (PDF)
Accordong to JST XH Catalog (PDF) , there is no JST XHR, but JST XHP. The “P” in “XHP” stands for “plug”. Means XHP is the plug housing of JST XH family. The “R” stands for “receptacle” (ex: JST SM catalog with both SMR and SMP), as you see on XH catalog, this is no XHR. It could be an old version name.
Following is the part number definition of XHP:
The JST PH and PHR connectors are often confused, but they’re essentially the same—PHR isn’t a distinct series.
“PH” is the official JST series name, a 2.0 mm pitch, wire-to-board, crimp-style connector, supporting AWG #30 to #24 wires and a 2 A current rating, ideal for compact applications like battery packs.
“PHR” is typically a shorthand or typo referring to the PH series’ receptacle housing (e.g., PHR-2, PHR-3), not a separate connector type.
So, there’s no real difference—PHR is just a part-specific reference within the PH family.
Just use a tooling (can be a ball-point pen) to press down the locking tang of the terminal. And then withdraw it by pull the crmiped wire out of the JST XHP housing.
Better not reuse the crmiped wire by only restoring the locking tang. Crimp a new terminal!
