KIOXIA (Toshiba)
4GB e-MMC 5.0, 153-ball 11.5 x 13 mm WFBGA, 1.8/3.3 V VCCQ – KIOXIA (Toshiba) legacy density out of the current lineup
The KIOXIA (formerly Toshiba Memory) THGBMNG5D1LBAIL is a 4GB managed NAND e-MMC 5.0 device in the JEDEC-standard 153-ball 11.5 x 13 x 0.8 mm WFBGA package, with a 3.3 V core supply and 1.8 V or 3.3 V I/O, rated for -25 °C to +85 °C. Low-density eMMC of this type is the boot and application storage in set-top boxes, IP cameras, smart-home devices, POS terminals and industrial HMI panels, many of which are still in volume production with firmware locked to the original part. KIOXIA’s current e-MMC lineup no longer lists this part number, so OEMs and EMS providers are buying remaining stock on the open market. Cerametronics sources THGBMNG5D1LBAIL with date code and lot traceability and quotes within 24 hours.

FAQ
Is THGBMNG5D1LBAIL still available from KIOXIA?
The part no longer appears in KIOXIA's current e-MMC product brief, where the 4GB density is offered as THGBMNG5D1LBAIT (11 x 10 mm) and THGBMTG5D1LBAIL (11.5 x 13 mm). Designs that need the original part number for firmware or qualification reasons rely on remaining distributor and spot inventory.
Can I switch to the successor 4GB eMMC without requalification?
THGBMTG5D1LBAIL uses the same 153-ball 11.5 x 13 mm footprint and eMMC 5.0 interface, so hardware changes are usually not needed, but it is a different NAND/controller generation and host firmware should be re-verified. We can quote the original THGBMNG5D1LBAIL or the successor.
