Buying Guide
Summary

Mercury Electronics Ind. Co. Ltd 18QHTF21-68-200-PD is sourced in Oscillators category when teams want clear constraints and a repeatable validation path. Key specs include Description (68.2 MHz XO 1.8V 2.0X1.6 MM PD), Series (18QHTF21), Type (XO (Standard)), Packaging (Strip), and Supply (1.8V).

Selection Notes
  • For 18QHTF21-68-200-PD, validate the operating temperature range (-40°C ~ 85°C) for your environment and margin.
  • Confirm Size / Dimension (0.079" L x 0.063" W (2.00mm x 1.60mm)) and ensure it matches your integration requirements.
  • Verify the package/case (4-SMD, No Lead) fits your mechanical constraints and assembly process.
Alternates & Substitutions
  • In Oscillators, confirm that alternates preserve startup states and fault behavior so system behavior does not change quietly.
  • Confirm startup states and fault behavior are equivalent so the alternate does not change system behavior during brownouts or resets.
  • Start with mechanical equivalence and keep package/case 4-SMD, No Lead, mounting Surface Mount, packaging Strip aligned so the alternate is footprint-safe.
  • Confirm compliance/qualification needs (for example RoHS/REACH or grade) before approving a second source for production.

Application Scenarios

Mercury Electronics Ind. Co. Ltd 18QHTF21-68-200-PD in the Oscillators category is typically selected when engineers need predictable, spec-driven behavior in a production design. In many platforms, clock parts directly influence BER, sampling accuracy, and long-term stability during 24/7 operation. Timing devices are often chosen for predictable startup, stable jitter performance, and clean distribution across noisy boards. In automotive infotainment and camera links, stable clocking is validated across vibration and thermal cycling. Within automotive infotainment and camera links, they support high-speed interfaces that must tolerate thermal cycling and vibration without frame errors. In measurement equipment, clean clocks reduce converter spurs and improve repeatability in benchtop instruments used for calibration workflows. For most teams, reducing uncertainty early is what keeps bring-up and qualification on track. As a result, qualification becomes easier to repeat and less sensitive to lot-to-lot variation.

Compatibility Advice
  • Validate startup, enable, and sequencing behavior so the system does not boot into undefined clock states during bring-up and production test.
  • To reduce integration risk, confirm drive level, load capacitance, and layout keep the resonator inside its recommended operating region over life. This keeps acceptance criteria measurable and repeatable.
Project Fit
  • A practical check is to define acceptance criteria and validate the key assumptions with production-like fixtures before approving substitutions.
