K4B4G1646E-BCMA replacement — HGD34G16S18

Searching for a drop-in replacement for K4B4G1646E-BCMA? The matching HGCHIPS part is HGD34G16S18 — DDR3 SDRAM, 4Gbit, 1866. It is engineered as a pin-to-pin compatible alternative to the 三星 Samsung K4B4G1646E-BCMA, so you can swap the part without a PCB redesign or a firmware change.

K4B4G1646E-BCMA vs HGD34G16S18 — parameter comparison

Four checks before you swap

• Confirm the full original part suffix (speed, voltage, temperature grade) — a different suffix can mean a different spec.
• Confirm package and ball map: this part is pin-to-pin compatible, but run your own IQC first-article check.
• Confirm firmware/timing: normally no re-tuning is needed; validate in small quantity for special platforms.
• Confirm acceptance criteria: per-lot test reports can be supplied as incoming-inspection evidence.

Why qualify HGCHIPS as a second source

• Pin-to-pin / drop-in — footprint, ball map and function compared part-by-part against the original datasheet. No PCB redesign, no firmware change.
• Lot-level test reports — 100% inspection at our Shenzhen test center, with per-lot data you can archive for IQC.
• Stock ships in 48h — stock lines leave Shenzhen within 48 hours; long-life programs can be price-locked.
• 10 pcs sample MOQ — validate a second source in small quantity before releasing volume; sample cost is credited against the first production order.

Frequently asked questions

K4B4G1646E-BCMA — can it drop in without board changes?

No board changes. K4B4G1646E-BCMA is designed as a pin-to-pin drop-in: package and pin-out are checked field by field against the original datasheet, so it fits the existing PCB and firmware. Typical use is second-sourcing, EOL cover and allocation shortages.

Which parameters should I verify before a replacement?

Verify the spec fields listed above — density, organization, speed grade, voltage, package and temperature range — against the original part number, then run a small pilot batch before volume. Any field we cannot match is stated rather than assumed.

K4B4G1646E-BCMA — samples and lead time?

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. Parts are 100% inspected before shipment and batch test data is available for IQC.
