Will it survive the hot air? Yes — the MEMS resonator is less thermally massive than a quartz crystal, so the package reflows evenly with a standard lead-free profile. Just watch the soak time: the 0.90 mm height means the body heats fast, and the no-lead pads need enough paste volume to form a visible fillet at the side. Pin 1 orientation is marked on the package — confirm the pad layout matches the 6-SMD no-lead footprint before committing the board; a misaligned pad pattern lifts the part, not the pad.","metaTitle":"DSC1121BE5-024.0000 MEMS XO 24 MHz ±10 ppm CMOS – Microchip","metaDescription":"DSC1121BE5-024.0000: Active MEMS XO, 24 MHz, CMOS output, ±10 ppm stability, 2.25-3.6 V supply, -20 to 70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1121","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"24 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative in the DSC1121 family?","answer":"The DSC1121 series shares the same 6-SMD no-lead package and pinout across frequency variants.
