Sourcing and availability
The UCC2920DP: This part is available through independent distribution. We source it to order against an RFQ — no stock-on-shelf claim here, but we can confirm current availability and pricing at quote time. For a BOM line that needs this exact order code, the active lifecycle means the supply chain is stable; no need to chase surplus or pay a spot premium unless lead times tighten across the supervisor-IC category.
Functional equivalent — TLV803EA29VDBZR
If you are looking for a drop-in functional alternative, the TLV803EA29VDBZR is a close peer. It is a simple reset/power-on reset IC with an active-low, open-drain output. Key differences: the TLV803 is surface-mount (SOT-23), RoHS compliant, and rated for -40°C to 125°C. The UCC2920DP comes in a Bulk package — likely through-hole or a larger footprint — so the board-level swap is not pin-to-pin without a layout change. For new designs where RoHS compliance and smaller footprint matter, the TLV803 is worth evaluating. For existing boards locked to the UCC2920DP footprint, stick with the original.
