HGCHIPS HGD34G08M21 Replacement Cross-reference — 4Gb 512Mb x8 DDR3-2133

HGCHIPS HGD34G08M21 is a spec-matched option for the Micron DDR3L family: density 4Gb, organization 512Mb x8, speed grade DDR3-2133, voltage 1.35V (DDR3L) and package TFBGA, aligned item by item against the original datasheet.

Status: in production and available (spec-matched). Production status has been confirmed by our FAE, so quotation and scheduling are available now. This page claims specification matching only (density / organization / speed / voltage) — no pin-to-pin compatibility. For a pin-level conclusion, send us the complete part number and platform details and our FAE will confirm pin-out and die revision in writing.

Before you design it in

  • This part is in production and available, offered as a spec-matched option; ask our FAE for a pin-level conclusion before ramp-up.
  • Speed grades step down: the 1866 MT/s grade covers 1600 MT/s and slower platforms — check the controller datasheet for the actual frequency.
  • Commercial and industrial grades carry a clear price premium; step up the temperature grade only when the platform truly requires it.
  • Validate in small quantities first — samples from 10 pcs, credited against your first order.
