HGCHIPS — pin-to-pin compatible memory & power modules
HGCHIPS (Zhongshan Huagong Technology Co., Ltd.) is a China-based semiconductor supply partner focused on pin-to-pin compatible memory and power modules. We engineer drop-in replacements for Samsung, SK Hynix, Micron, Nanya and Winbond DRAM as well as ADI µModule power parts — so a swap does not require a PCB redesign or a firmware change.
What we supply
- DDR2 / DDR3 / DDR4 SDRAM — 1 Gbit to 16 Gbit, commercial and industrial grades
- LPDDR4 / LPDDR4X
- ADI µModule compatible power modules (LTM4600 / LTM4620 / LTM4628 / LTM4644 / LTM8052 series and more)
- Original brand memory stock for shortage and EOL situations
Why buyers qualify us as a second source
- Pin-to-pin / drop-in — footprint, ball map and function compared part-by-part against the original datasheet
- Lot-level test reports — 100% inspection at our Shenzhen test center, with per-lot data for your IQC
- Stock ships in 48h — stock lines leave Shenzhen within 48 hours; long-life programmes can be price-locked
- 10 pcs sample MOQ — validate before releasing volume; sample cost is credited against your first order

Frequently asked questions
What does HGCHIPS (Zhongshan Huagong Technology Co., Ltd.) offer?
Import-substitution and pin-to-pin compatible parts for memory (DDR3, DDR4, LPDDR4/LPDDR4X) and ADI µModule power modules (LTM46xx / LTM80xx), used for second-sourcing, EOL cover and allocation shortages.
Can a replacement go onto the existing board?
The compatible parts are designed as pin-to-pin drop-ins: package and pin-out are checked field by field against the original datasheet. We still recommend confirming the listed spec fields and running a small pilot batch before volume.
What are the sample and lead-time terms?
Samples from 10 pcs, credited against the first order. In-stock items ship from Shenzhen within 48 hours; long-lead projects can be price-locked. Batch test data is available for IQC.
