JQC-3FF/12-1HS(551)为宏发(HF)出品的超小型大功率直流继电器,线圈标称电压12V,单刀单掷常开(SPST-NO)触点形式。封装为插件式(19×15.5mm),体积小巧,适合空间受限但需较大开关容量的场合。注意:该型号已标注停产,选型时请考虑可替代器件或库存情况。
该型号已停产,若需替代,请与供应商或宏发官方联系确认等效型号。选型时重点匹配:线圈电压/功耗、触点容量(电流/电压)、封装尺寸和引脚兼容性。对环境友好和符合RoHS需求的替代品尤为重要。
JQC-3FF/12-1HS(551)是一款体积小、线圈功耗低且能承担较大开关电流的插件式继电器,适合多种控制与开关场景。但因已停产,推荐尽快完成替代器件验证或采购现有库存,并在使用时关注驱动抑制与负载类型对触点寿命的影响。若需我方协助筛选同等规格的替代型号或核对引脚兼容性,可提供电路原理图和安装尺寸以便进一步确认。

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.
