2-520193-2 产品概述
一、产品简介
2-520193-2 为 TE Connectivity（泰科电子）出品的 ULTRA‑FAST 187 系列受插端子总成（ASY REC 22‑18 TPBR），为美国产型号。该件为全绝缘插簧式受端，适配 4.75 mm（0.187"）对插片，主要用于可靠的线对板/线对线快速连接场合。
二、主要参数
- 接插规格：4.75 mm（0.187"）
- 线规（AWG）：18 ~ 22
- 允许绝缘外径（O.D）：≤ 3.43 mm
- 全长：21.72 mm
- 对插插片厚度：0.81 mm
- 端子类型：插簧端子（插入式/受端）
- 护套类型/颜色：全绝缘，红色
- 触头材质：黄铜（基材）
- 触头镀层：锡
三、材料与表面处理
触头采用黄铜材质，兼顾导电性与机械强度；锡镀层提供良好的抗氧化和焊接/接触性能，适合一般环境下的长期接触可靠性。全绝缘护套增加电气安全性并减少短路风险，红色护套有利于快速识别电路极性或功能分组。
四、适配与装配建议
本端子适用于 18‑22 AWG 的剥线后压接或插入固定连接，所用导线的绝缘外径不得超过 3.43 mm，以保证护套与端子完好装配并维持机械强度。受端设计用于匹配 4.75 mm（0.187"）对插片、厚度约 0.81 mm 的公插片。建议使用与 TE 指定匹配的压接或装配工具以确保压接质量并避免接触不良。
五、典型应用场景
该型号常用于家电、工业控制、继电器与接触器的线缆连接、配电箱端子、测试与维修替换件等需要快速插拔的低中功率连接场合；红色全绝缘护套使其在多线束、分色管理中便于识别。
六、优势与使用注意
优势：结构紧凑、插拔便捷、适配通用 0.187" 快速接插件标准，材料与镀层兼顾导电与耐腐蚀性，厂家品质与美国产地可追溯性强。
注意事项：装配前确认线规与绝缘外径符合标称范围；避免超载使用（按系统设计电流选型）；储存环境应防潮、防尘以保持锡层与接触面洁净；如用于特殊环境（高温、海洋性腐蚀等），建议评估是否需更高等级表面处理或密封措施。
如需进一步的电气额定、电流承载能力或与特定公端/插片的互换清单，可参照 TE 官方数据表或提供具体应用环境以便给出更精准的选型建议。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
