HFD23/012-1ZS 是宏发 (HF) 出品的一款小型单刀单掷(SPST)信号继电器,采用 DIP 封装,外形尺寸约 12.5 × 7.5 mm。该继电器以 12V 线圈驱动、低线圈功耗和金属接点镀金处理为特点,非常适合用于低电平信号切换、电源管理与电子控制等场合。其设计兼顾体积、功耗与可靠性,适合 PCB 直接插装使用。
HFD23/012-1ZS 为通用 DIP 直插封装,便于在常规 PCB 上插装或通过孔波峰焊接。紧凑的机械尺寸使其适合密集布局的电路板和小型设备。具体引脚排列与焊盘尺寸应参考厂商 Datasheet 以保证与 PCB 孔位和丝印对齐。
如果应用为低电平信号切换或要求小体积、低功耗且工作在 ≤30 VDC / ≤1 A 的场景,HFD23/012-1ZS 是性价比较高的选择。若需切换更大电流、反复快速切换或在严苛工业环境(强腐蚀、极端温度)下工作,应考虑额定更高或封装更大、具备更强保护的继电器方案。
如需更详细的引脚定义、机械图和寿命(电气/机械)数据,请查阅宏发官方 Datasheet 或联系供应商获取完整技术资料。

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.
