Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct frequency, tolerance, and package variant. Confirm RoHS compliance status if required by regulatory standards. Cross-reference the part number with authorized distributors to avoid counterfeit components. Ensure the selected variant matches the required supply voltage and output load specifications for the target application circuit.

Oscillators Selection Notes

Select this oscillator when a low-frequency, stable timing source is required for CMOS-based digital circuits. Consider the ±25ppm stability specification relative to system timing requirements. Evaluate the 3.3V supply constraint against available power rails. The compact 4-SMD footprint should be assessed against PCB layout constraints. Verify thermal performance within the -20°C to +70°C operating range for the intended environment.

Oscillators Part Context

This component belongs to the ISM95 series of surface-mount oscillators from ILSI America LLC. The series offers various frequency options within a standardized 2.0mm x 2.5mm ceramic package. These devices are designed as direct replacements for through-hole crystals or larger oscillator packages in modern high-density PCB layouts. The series supports both TTL and HC-MOS output levels, providing flexibility for different logic family interfaces.

Oscillators Replacement Considerations

Direct substitutes must match the 1MHz frequency, 3.3V supply, and 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics such as output load and stability. Check for equivalent enable/disable functionality if present in the original design. Consult manufacturer cross-reference lists for validated alternative part numbers.
