Technical Specification: The Standard Pitch<\/h2>\n<p data-path-to-node=\"7\">According to the official <b data-path-to-node=\"7\" data-index-in-node=\"26\">JST (Japan Solderless Terminals)<\/b> technical datasheets, the XH series is designed with a <b data-path-to-node=\"7\" data-index-in-node=\"114\">2.50mm pitch<\/b>.<\/p>\n<p data-path-to-node=\"8\">The series was developed for high-density mounting in a wide range of electronic equipment. Its primary metrics are metric-based:<\/p>\n<ul data-path-to-node=\"9\">\n<li>\n<p data-path-to-node=\"9,0,0\"><b data-path-to-node=\"9,0,0\" data-index-in-node=\"0\">Official Pitch:<\/b> 2,50 \u043c\u043c<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"9,1,0\"><b data-path-to-node=\"9,1,0\" data-index-in-node=\"0\">\u0422\u0435\u043a\u0443\u0449\u0438\u0439 \u0440\u0435\u0439\u0442\u0438\u043d\u0433:<\/b> 3A AC\/DC (AWG #22)<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"9,2,0\"><b data-path-to-node=\"9,2,0\" data-index-in-node=\"0\">\u041d\u043e\u043c\u0438\u043d\u0430\u043b\u044c\u043d\u043e\u0435 \u043d\u0430\u043f\u0440\u044f\u0436\u0435\u043d\u0438\u0435:<\/b> 250V AC\/DC<\/p>\n<\/li>\n<\/ul>\n<h2 data-path-to-node=\"10\">2. Why is JST XH Frequently Misidentified as 2.54mm?<\/h2>\n<p data-path-to-node=\"11\">The confusion between 2.50mm and 2.54mm is not accidental. It stems from three primary factors:<\/p>\n<h3 data-path-to-node=\"12\">A. The Legacy of the 0.1-inch Standard<\/h3>\n<p data-path-to-node=\"13\">Historically, the electronics industry was dominated by U.S. imperial standards. The <b data-path-to-node=\"13\" data-index-in-node=\"85\">0.1-inch (2.54mm)<\/b> pitch became the universal standard for pin headers, breadboards, and perforated boards (perf-boards). Because 2.50mm and 2.54mm are visually nearly identical, many engineers and buyers colloquially group them under the &#8220;2.54mm&#8221; umbrella.<\/p>\n<h3 data-path-to-node=\"14\">B. Physical Tolerance in Low Pin Counts<\/h3>\n<p data-path-to-node=\"15\">For connectors with a low number of circuits (e.g., 2P or 3P), a 2.50mm female housing can often be forced onto a 2.54mm male header. This &#8220;accidental compatibility&#8221; in low pin counts creates the false impression that the two standards are interchangeable.<\/p>\n<h3 data-path-to-node=\"16\">C. Search Engine and Supply Chain Optimization<\/h3>\n<p data-path-to-node=\"17\">In the e-commerce landscape, suppliers often include both &#8220;2.50mm&#8221; and &#8220;2.54mm&#8221; in product titles to maximize search visibility. Over time, &#8220;XH 2.54&#8221; has become a common but technically incorrect search term that reinforces the myth.<\/p>\n<hr data-path-to-node=\"18\" \/>\n<h2 data-path-to-node=\"19\">3. The Risk of Cumulative Error<\/h2>\n<p data-path-to-node=\"20\">While a <b data-path-to-node=\"20\" data-index-in-node=\"8\">0.04mm<\/b> difference seems negligible, it is a <b data-path-to-node=\"20\" data-index-in-node=\"52\">linear cumulative error<\/b>. As the pin count increases, the misalignment becomes critical.<\/p>\n<table data-path-to-node=\"21\">\n<thead>\n<tr>\n<td><strong>Circuits (P)<\/strong><\/td>\n<td><strong>2.50mm Standard Pitch<\/strong><\/td>\n<td><strong>2.54mm Cumulative Pitch<\/strong><\/td>\n<td><strong>Cumulative Error<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span data-path-to-node=\"21,1,0,0\">2P<\/span><\/td>\n<td><span data-path-to-node=\"21,1,1,0\">2,50 \u043c\u043c<\/span><\/td>\n<td><span data-path-to-node=\"21,1,2,0\">2,54 \u043c\u043c<\/span><\/td>\n<td><span data-path-to-node=\"21,1,3,0\">0.04mm<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"21,2,0,0\">5P<\/span><\/td>\n<td><span data-path-to-node=\"21,2,1,0\">10.00mm<\/span><\/td>\n<td><span data-path-to-node=\"21,2,2,0\">10.16mm<\/span><\/td>\n<td><span data-path-to-node=\"21,2,3,0\">0.16mm<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"21,3,0,0\">10P<\/span><\/td>\n<td><span data-path-to-node=\"21,3,1,0\">22.50mm<\/span><\/td>\n<td><span data-path-to-node=\"21,3,2,0\">22.86mm<\/span><\/td>\n<td><span data-path-to-node=\"21,3,3,0\">0.36mm<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"21,4,0,0\">20P<\/span><\/td>\n<td><span data-path-to-node=\"21,4,1,0\">47.50mm<\/span><\/td>\n<td><span data-path-to-node=\"21,4,2,0\">48.26mm<\/span><\/td>\n<td><span data-path-to-node=\"21,4,3,0\"><b data-path-to-node=\"21,4,3,0\" data-index-in-node=\"0\">0.76mm<\/b><\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3 data-path-to-node=\"22\">Consequences of Misalignment:<\/h3>\n<ol start=\"1\" data-path-to-node=\"23\">\n<li>\n<p data-path-to-node=\"23,0,0\"><b data-path-to-node=\"23,0,0\" data-index-in-node=\"0\">Mechanical Stress on Solder Joints:<\/b> If a 2.50mm XH header is forced into 2.54mm PCB holes, the pins will be tensioned outward.
