PH2.54-01-20PZD是讯普(XUNPU)推出的通用型单排直插方针排针,针对20位信号/小功率电源传输场景设计,适配2.54mm国际标准间距。核心定位为“高可靠性、低成本、易集成”,广泛覆盖以下领域:
该产品参数围绕“结构兼容性、电气稳定性、环境适应性”优化,核心参数如下:
参数类别 具体参数 关键说明 结构参数 1×20P(单排20位)、间距2.54mm、方针、直插 单排节省空间,方针接触更稳定 电气参数 额定电流3A、黄铜触头、镀金镀层 满足小功率电源+信号传输,接触电阻≤20mΩ 机械参数 配合针长6mm、塑高2.5mm、端接针长3mm 配合深度足够,塑壳紧凑,焊接适配性好 环境参数 工作温度-40℃~+105℃、黑色塑壳 宽温适应高低温场景,耐脏易识别相比圆针,方针的平面接触面积更大(同直径下约为圆针的1.5倍),电流传输时发热更低;同时方针的“线性接触”特性,插入排母时不易偏移,减少针脚弯曲风险。
2.5mm塑高(塑料基座高度)是行业紧凑设计,在保证针脚间距精度(±0.1mm)的前提下,可节省PCB垂直空间约30%,适合追求轻薄的消费电子或小型工业设备。
端接针长3mm,刚好匹配标准PCB通孔(直径0.81.0mm、深度23mm),焊接时锡液可充分填充间隙,减少假焊、虚焊概率;配合针长6mm,插入排母时有效接触长度足够,插拔后不易松动。
触头采用优质H65黄铜,导电率达1.07×10^7 S/m(接近纯铜),机械强度适中,可承受多次插拔不变形;黄铜耐腐蚀性能优于纯铜,避免长期使用中触头氧化。
触头表面镀硬金(厚度≥0.5μm),金的化学稳定性极强,潮湿/高温环境下仍保持低接触电阻;硬金硬度(约120HV)高于纯金,减少插拔磨损,插拔寿命可达500次以上。
塑壳采用PA66工程塑料,可承受波峰焊(240260℃)、回流焊(250270℃)高温,耐老化性能优异,长期使用不裂不变形;黑色外观耐脏,便于设备内部识别。
工作温度-40℃~+105℃,适配:
2.54mm是国际通用间距,与90%以上2.54mm排母、跳线帽兼容,无需定制配件,可直接集成到现有系统,降低设计/采购成本。
该产品由讯普按行业标准生产,质量稳定、性价比突出,是各类电子设备内部信号/小功率电源连接的理想选择。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
