Processors with fast-starting internal oscillators or those that need a longer hold-off for external crystal start-up may need a longer timeout — this part's 100 ms minimum is a floor, and the actual timeout can be longer but not shorter. If your BOM requires a precise timeout or a programmable delay, this fixed supervisor may not fit. ## Package and mounting The X5043S8Z comes in an 8-SOIC narrow-body package (3.90 mm body width) for surface-mount assembly. The supplier device package is also 8-SOIC, so no footprint mismatch between the generic case code and the shipped part. Plan for manual tube loading or a tube-to-reel transfer step. ## Lifecycle and compliance It is ROHS3 compliant, which covers the full RoHS exemption list including lead in high-temperature solder.","metaTitle":"X5043S8Z Simple Reset/Power-On Reset, 4.38V Threshold","metaDescription":"Renesas X5043S8Z is a Simple Reset/Power-On Reset IC with 4.38V threshold, active-low open-drain output, 100ms min reset timeout, 8-SOIC surface mount","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Tube","Mounting Type":"Surface Mount","Reset Timeout":"100ms Minimum","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.38V","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"8-SOIC","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.12","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.12000","currency":"USD"},{"qty":10,"price":"$5.50000","currency":"USD"},{"qty":25,"price":"$5.19920","currency":"USD"},{"qty":100,"price":"$4.50610","currency":"USD"},{"qty":250,"price":"$4.27496","currency":"USD"},{"qty":500,"price":"$3.83592","currency":"USD"},{"qty":1000,"price":"$3.64060","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5312c3799f736e5e33ae74275dc7f72c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is X5043S8Z RoHS compliant?","answer":"Yes, the X5043S8Z is ROHS3 compliant."},{"question":"What is the X5043S8Z output type?","answer":"The output is open drain or open collector, active low."},{"question":"Can X5043S8Z replace X5043S?","answer":"The X5043S8Z is a surface-mount variant of the X5043S family. The S8Z suffix indicates the 8-SOIC package and tube packaging. If the original X5043S was also in an 8-SOIC package, the X5043S8Z is a direct replacement.
