Introduction
Selecting the correct JST connector equivalent for a printed circuit board (PCB) design requires matching pitch, housing configuration, and mounting style to the target application. As of September 2026, KONNRA’s connector series remain cross-referenced against original JST part families, giving engineers a validated domestic alternative for JST-pitch connectors used in automotive, industrial, consumer electronics, networking, and medical device PCB layouts.
This article organizes KONNRA’s JST-equivalent connector series by pitch, so designers can quickly identify the correct family for a given board-to-wire or wire-to-wire interface.
What Is JST Series Cross-Referencing and Why Does Pitch Matter?
Pitch refers to the center-to-center spacing between adjacent contacts on a connector housing, measured in millimeters. Pitch determines current-carrying capacity, board footprint, and mechanical compatibility with mating connectors. Cross-referencing means a manufacturer’s connector family shares dimensional and functional compatibility with an original manufacturer’s part number — in this case, JST. KONNRA’s connector series are cross-referenced to JST (as well as HIROSE, Molex, and YEONHO) original part families, enabling direct domestic replacement without redesigning the PCB footprint.
