LTM4644T vs HG4644T — 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 compatible — package and pinout compared part-by-part against the original ADI µModule; no re-layout required.
• 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.
