Active production — no end-of-life pressure on this BOM line
The TPA2036D1YZFT: RoHS3 compliance is confirmed on the record, which means the part clears EU restriction requirements without an exemption expiry date to manage.
2.5W mono into 4Ω — what that means for speaker selection
Rated 2.5W x 1 @ 4Ω, the TPA2036D1YZFT delivers enough continuous power for a single small speaker in a portable speaker dock, a handheld radio, or a notification chime circuit. Supply voltage spans 2.5V to 5.5V, so a single-cell Li-ion battery at 3.6V nominal or a regulated 5V USB rail both work without an extra regulator.
DSBGA package — field-swap reality check
The 9-DSBGA (0.4mm pitch typical for this class) is a wafer-level chip-scale package — there is no plastic overmold, and the solder balls are the only standoff. If a field swap is likely, plan for a pre-programmed spare on a small adapter board.
