While the "NEW" revision is fresh (release date: Q2 2024), industry roadmaps already hint at a successor. By late 2026, expect the BT2016R73146ULTSC NEW+ or BT2024R82150GAN – a gallium nitride (GaN) variant with 5x lower switching losses. However, for the next 24-36 months, the BT2016R73146ULTSC NEW remains the gold standard for robust, ultra-low-threshold power management.

"BT" strongly connects to battery technology. 2016 might indicate the design year, and r73146 could be a cell configuration code (e.g., 73mm height, 146mm length – a nonstandard cylindrical cell size). "ultsc" might stand for Ultra-Low Self-Discharge Cell – a feature in some LiFePO4 or NiMH batteries. If you encounter this keyword, check battery pack datasheets from Asian manufacturers (Samsung SDI, LG Chem, or Chinese BMS suppliers).

Portable ultrasound and patient monitors require the low-noise performance that the ULTSC family is known for. The "NEW" version adds fault-tolerant redundancy. bt2016r73146ultsc new

If you are replacing an older board with the "NEW" designation, you need the delta. Here is the engineering change log as pieced together from supply chain notices:

| Feature | BT2016R73146ULTSC (Original) | BT2016R73146ULTSC NEW (Current) | | :--- | :--- | :--- | | Quiescent Current (Iq) | 120 µA | 102 µA (15% improvement) | | Thermal Resistance (Θja) | 45°C/W | 38°C/W (Better heat dissipation) | | Internal LDO Output | Fixed 3.3V | Programmable 1.8V / 2.5V / 3.3V | | RoHS Compliance | Exemption 7a (lead in solder) | Fully RoHS 3 compliant | | Firmware | v1.0 (no CRC check) | v2.1 (CRC-16 on every packet) | | Lead Time | Obsolete (NFFD – Not For Future Design) | Active (until at least 2028) | While the "NEW" revision is fresh (release date:

Critical Warning: The "NEW" version is pin-compatible with the original but requires a slightly different passive component network (specifically, a 2.2µH instead of 1.5µH inductor on the output). Do not drop-in replace without consulting the addendum datasheet.

As of this writing, the BT2016R73146ULTSC NEW is listed in the inventory of: "BT" strongly connects to battery technology

Given the lack of matches in public datasheets, it is highly probable that bt2016r73146ultsc is a non-public, factory-internal string used by a specific contract manufacturer (CM) for one of the following:

The ultra-low threshold allows the device to wake from sleep modes in nanoseconds, making it ideal for battery-powered sensors monitoring vibration, temperature, or pressure in factories.
