Procurement Notes

Verify component availability status carefully as this item is marked obsolete. Confirm compatibility with existing designs before procurement. Check for end-of-life notices or last-time-buy windows from authorized distributors. Ensure replacement strategies are evaluated if long-term supply continuity is required for production runs.

Selection Notes

Select this component when a cost-effective, single-chip timing solution is needed without external capacitors. Consider the specific frequency tolerance requirements of the application. Evaluate thermal constraints against the specified operating range. Verify pin compatibility with legacy PCB footprints requiring a 2.50 mm lead pitch.

Part Context

This ceramic resonator belongs to the ZTT series from ECS Inc., which focuses on compact timing solutions. It serves as an alternative to discrete crystal oscillator setups by combining the resonant element and load capacitors into one package. The radial lead configuration allows for easy insertion into through-hole manufacturing processes common in various electronic assemblies.

Replacement Considerations
