The SOT-23-5 package and 1.14V threshold are specific enough that a drop-in substitute from another supplier requires careful parametric review. ## Industrial temperature grade, SOT-23-5 footprint Surface mount only.","metaTitle":"TPS3128E12DBVR Simple Reset IC, 1.14V Threshold, Obsolete","metaDescription":"Texas Instruments TPS3128E12DBVR simple reset/power-on reset IC, active low open drain output, 1.14V threshold, 100ms timeout, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Reset Timeout":"100ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"TPS3128","Voltage - Threshold":"1.14V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/33ce582e7a8405bef9aabe534ac434b3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3128E12DBVR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TPS3128E12DBVR?","answer":"Any substitute must match the 1.14V threshold, active low open drain output, 100ms timeout, and SOT-23-5 footprint.
