Engineering Selection Recommendations

Both the DSC1001CE2-100.0000T and ASEMB-100.000MHZ-LY-T are active production components with full regulatory compliance. Selection between these parts should be based on the following factors:

The Microchip DSC1001CE2-100.0000T provides tighter frequency stability at ±25ppm and lower maximum supply current at 8.7mA, making it suitable for applications with strict power budgets or frequency precision requirements within the -20°C to 70°C operating range.

The Abracon ASEMB-100.000MHZ-LY-T offers superior frequency stability at ±10ppm and an extended operating temperature range of -40°C to 85°C, accommodating wider environmental conditions. The higher maximum supply current of 16mA should be evaluated against application power requirements.

Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Identical physical footprints and MSL ratings ensure direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ASEMB-100.000MHZ-LY-T directly replace the DSC1001CE2-100.0000T on the PCB?

A: Yes. Both parts share identical physical dimensions (3.20mm x 2.50mm), seated height (0.90mm), and surface-mount package footprints. No PCB layout modifications are required.

Q: What are the differences in frequency stability between these parts?

A: The DSC1001CE2-100.0000T specifies ±25ppm frequency stability, while the ASEMB-100.000MHZ-LY-T specifies ±10ppm. The Abracon part provides tighter tolerance. Application requirements determine which specification is acceptable.
