Buying Guide
Summary

Renesas Electronics Corporation 1338D-31DVGI is sourced in Real Time Clocks category when teams want clear constraints and a repeatable validation path. Key specs include Description (1338D-31 REAL TIME CLOCK), Type (Clock/Calendar), Packaging (Tube), Supply (3.3V ~ 5.5V), and Temperature (-40°C ~ 85°C (TA)).

Selection Notes
  • For 1338D-31DVGI, verify the package/case (8-TSSOP, 8-MSOP (0.118", 3.00mm Width)) fits your mechanical constraints and assembly process.
  • Confirm the supply voltage requirement (3.3V ~ 5.5V) and any rail tolerance constraints.
  • Confirm the data interface (I2C) matches your host interface and timing requirements.
Alternates & Substitutions
  • For Real Time Clocks, compare the datasheet test conditions behind key specs and re-check the margins that were tightest during bring-up.
  • When evaluating alternates, treat package/case 8-TSSOP, 8-MSOP (0.118", 3.00mm Width), supplier package 8-TSSOP, mounting Surface Mount as non-negotiable unless you are re-spinning the PCB.
  • When in doubt, treat the swap as an ECO: define acceptance criteria, then validate under worst-case operating corners.
  • If you need a second source, provide (package 8-TSSOP, 8-MSOP (0.118", 3.00mm Width), supply 3.3V ~ 5.5V, interface I2C) and we will suggest options to evaluate under a clear test plan.

Application Scenarios

In the Real Time Clocks category, Renesas Electronics Corporation 1338D-31DVGI is often evaluated by how well it fits electrical, thermal, and mechanical constraints in the target system. Engineers often prefer timing parts with clear grounding and routing guidance, because layout decides whether jitter stays inside budget. For sampling and RF systems, deterministic lock behavior and stable phase noise can matter more than typical datasheet numbers. In data center equipment, clock quality influences BER margins and long-term stability under continuous load. In measurement equipment, clean clocks reduce converter spurs and improve repeatability in benchtop instruments used for calibration workflows. In embedded gateways, stable RTC and clocking improve logging accuracy and coordinated events across distributed sensor nodes.

Compatibility Advice
  • In practice, check fan-out loading and termination so clock edges remain clean across the full distribution tree on the assembled PCB.
Project Fit
  • A strong fit when you can verify Renesas Electronics Corporation 1338D-31DVGI for Real Time Clocks integration across temperature and supply corners, and you have defined jitter budgets and controlled routing for clock distribution.
