I'm looking for a 4-pin version of this 5-pin cable connector. It is for the Bluetooth module on a LiFePo4 BMS. You can see both PCB connectors in the 3rd picture. 2.5 mm pitch.

Can anyone identify the specific connector name?

4 pin board side

  • \$\begingroup\$ 2.5mm or 2.54mm? 2.5mm is an oddball pitch, 2.54mm (0.1'') is super-standard. Measure center-to-center between the outmost pins on the widest 6 pin connector, then divide by 6. \$\endgroup\$

My connector identification utility found these possible matches:

  • MANUF. - SERIES
  • JST - XA
  • Molex - Mini-Lock

Of those, the JST XA looks most likely.

    \$\begingroup\$ Thanks Davide. I should have included the word 'pitch' after 2.5 mm. Edited original post. I looked at just about every JST connector I could find. Will look at Molex now. \$\endgroup\$

  • \$\begingroup\$ That leaves 2: * MANUF. - SERIES * JST - XA * Molex - Mini-Lock \$\endgroup\$ Nov 21, 2021 at 15:47

I think this may be a "clone" of your connector. 2.50mm Pitch XHB crimp style connector.

Your images look more like the 2.0mm pitch version that I was looking for when I ran across your post. (mfg by Yeonho and TAIHUA)
