1775838-2 产品概述

一、产品简介

1775838-2 为 TE Connectivity(美国泰科)出品的一款 mSATA / mini PCI‑E 连接器(Type I,母座)。该产品采用卧贴(低剖面)安装方式,板上高度为 5.6mm,并配有安装柱(带柱)以增强机械稳定性。其机械形态基于标准 mini PCI‑E/mSATA 插座,用于承载 mSATA 固态硬盘或 mini PCI‑E 模块,实现存储或扩展式通信功能的板对板连接。

二、主要特点

  • 接口与兼容性:符合 mSATA/mini PCI‑E Type I 规格的接口形态,兼容常见的迷你 PCI‑E 卡和 mSATA SSD(需主机电路提供相应信号与供电)。
  • 低剖面设计:5.6mm 的板上高度适合笔记本、嵌入式与工业主板等空间受限场景,便于整机薄型化设计。
  • 母座形式:为插卡端母座,便于模块插拔并保证插接可靠性。
  • 机械固定:带柱设计提供额外的定位与支撑,降低振动或插拔应力对焊点和印制板的影响,利于批量装配与可靠性提升。
  • 品牌与质量保证:TE Connectivity 品牌背景,适用于对可靠性和可制造性有较高要求的量产应用。

三、典型应用

  • 笔记本电脑、上网本与超薄设备的 mSATA SSD 插槽;
  • 工业控制主板、通信网关与嵌入式系统的 mini PCI‑E 扩展模块接口(Wi‑Fi、3G/4G/5G 模块等);
  • 存储扩展卡与嵌入式存储解决方案;
  • 测试与开发平台中需要可插拔存储或通信模块的场景。

四、PCB 设计与安装注意事项

  • 机械定位:利用带柱进行定位和焊接固定,推荐在 PCB 设计中为柱脚留足焊盘或过孔,并考虑回流焊过程中的应力释放通道。
  • 高速信号布局:mini PCI‑E/mSATA 涉及高速差分对(PCIe/SATA),需按高速差分线规则布线(受控阻抗、差分一致性、最短路径、避免不必要的弯折与过孔),并保持地平面连续以降低串扰与丢失。
  • 接地与屏蔽:若模块带有金属屏蔽罩,应在 PCB 上提供相应接地焊点,纵观接地圈与接地过孔,以保证良好屏蔽与 EMI 性能。
  • 焊接工艺:该类型连接器通常支持回流焊或波峰焊配合人工/机器后焊固定柱的工艺流程,具体焊接温度曲线应参照制造商推荐工艺并与装配厂确认。

五、机械与可靠性建议

  • 插拔力与寿命:在设计时应考虑插拔频次,避免频繁拆插对连接器造成早期磨损;如需频繁更换模块,可在结构上增加导向与释放机构。
  • 振动与冲击:带柱结构有助于提高抗振动能力,但在高振动环境建议配合螺丝或卡扣进行二次固定。
  • 温度与环境:应用在工业或车规环境时,注意选用符合温度与湿度要求的连接器版本与材料,并做好防护与密封设计。

六、采购与替代注意

  • 型号核对:采购前请核实 1775838-2 的外形、插针排列、板上高度与带柱位置,以确保与现有 PCB 与模块机械兼容。
  • 兼容性验证:mSATA 与 mini PCI‑E 在电气层面不同(mSATA 使用 SATA 信号),选择时需确认主板或模块电路支持目标协议。
  • 替代件选择:若需要替代件,可在功能、剖面高度、带柱与否、母/公座形式以及制造商认证上严格匹配,优先选择同规格的工业级连接器以保障可靠性。

以上为 1775838-2 的关键特性与工程应用建议。在将该产品纳入设计或量产前,建议下载并参考 TE 官方的产品资料与机械图纸,或向供应商索要样品与推荐的装配指南以完成最终验证。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
