Verified Chinese Alternatives for Your BOM — Cost Down with Proof
Graded Cross-References
Every suggested alternative carries its verification level — from parametric match through documentary review to FAE verification — with parameter diffs and migration notes shown up front.
Genuine Stock, Authorized Channels
Quote-first sourcing through authorized channels: genuine parts, real lead times, traceable batches. We never publish fabricated stock numbers.
Transparent Landed Cost
DDP quotes with duties and tariffs clarified up front — the quoted price is the cost to your dock, no surprise charges on delivery.
Founded in 2001, ONEIC's parent company is a national high-tech enterprise dedicated to electronic components distribution. Headquartered in Beijing, China, with branches and global sourcing centers in Hong Kong, Shenzhen, Suzhou, Shanghai, the United States, Canada, the Netherlands, Singapore, and Germany. In 2010, we launched our proprietary digital procurement platform, pioneering a new model of integrated online-offline service. For over two decades, guided by the philosophy of "Genuine, Professional, Efficient", we have been committed to providing one-stop procurement of genuine electronic components for engineers, buyers, and manufacturers worldwide.
Our catalog spans semiconductors, connectors, passives, power management, embedded solutions, and circuit protection — with a dedicated cross-reference program covering Chinese first-tier brands such as GigaDevice, WCH, Espressif, Sunlord, SG Micro, Mornsun, CJT, Hongfa, Yangjie, Fenghua, Puya, and 3PEAK. Instead of inflated stock counters, we quote real availability from authorized channels within 24 hours.
We operate a modern ESD-safe warehousing and logistics center equipped with advanced temperature/humidity control and barcode management systems, shipping to a global delivery network. We also offer bilingual customer support, FAE on-site technical assistance, and BOM fulfillment services — backed by strict quality control and our promise of authenticity, safeguarding every customer's path to innovation.
