The JST EHR-8 is an 8-position, single-row receptacle housing from the EH series, molded in natural polyamide (PA66) with a 2.50mm pitch. This is a wire-to-board or wire-to-wire interconnect housing, typically used in internal appliance wiring, consumer electronics, and low-current industrial control harnesses where a compact, polarized, and keyed connection is needed.
Sourcing the EHR-8 for a BOM line
For a BOM requiring exactly 8 circuits, the EHR-8 is the direct match.
The EHR-8 mates with the matching EH series pin header (male, through-hole or crimp style) at the same 2.50mm pitch. The housing accepts female crimp socket contacts — the exact contact part number depends on the wire gauge being used; common choices in the EH series cover 22-28 AWG stranded wire. The housing provides primary retention; no secondary lock is present on this single-row design. The natural PA66 body gives a visual check that the housing is fully seated against the header shroud.
Pitch, polarity, and thermal limits
The 2.50mm pitch is a common wire-to-board spacing that balances routing density with enough creepage for low-voltage signal and power circuits. The housing is polarized — it will only mate in one orientation, which prevents mis-wiring in a harness.
