Parameter Comparison

Engineering Selection Recommendations

Both the ASE-44.000MHZ-ET and ASE-44.000MHZ-L-C-T are active production components from Abracon LLC with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific requirements:

Select ASE-44.000MHZ-ET when:

• Standard packaging configuration is required
• Operating temperature range of -20°C ~ 70°C is sufficient
• Frequency stability of ±100ppm meets application tolerance requirements

Select ASE-44.000MHZ-L-C-T when:

• Tape & Reel packaging is required for automated assembly processes
• Extended operating temperature range of -40°C ~ 85°C is necessary
• Enhanced frequency stability of ±50ppm is required for precision timing applications

Both parts maintain identical electrical performance in core parameters (frequency, output type, supply voltage, current consumption) and identical mechanical compatibility (package dimensions, mounting type, footprint).

Frequently Asked Questions (FAQ)

Q: Are these parts pin-compatible? A: Yes. Both parts use the identical 4-SMD, No Lead package with matching dimensions (3.20mm L x 2.50mm W x 1.20mm H max) and surface mount footprint. Direct PCB layout compatibility is maintained.

Q: What is the primary difference between these oscillators? A: The ASE-44.000MHZ-L-C-T offers improved frequency stability (±50ppm versus ±100ppm) and extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C). The packaging configuration differs: standard versus Tape & Reel (TR).

Q: Can I use ASE-44.000MHZ-L-C-T as a direct replacement for ASE-44.000MHZ-ET? A: Yes. The substitute part maintains all critical electrical parameters (frequency, voltage, current, output type, enable/disable function) and mechanical parameters (package type, dimensions, mounting type). Enhanced specifications represent improved performance characteristics.

Q: Does the Tape & Reel packaging affect electrical performance? A: No. Packaging configuration does not affect electrical performance. Tape & Reel is a production packaging format used for automated assembly processes and does not alter component functionality or electrical characteristics.

Q: Are both parts suitable for industrial temperature applications? A: The ASE-44.000MHZ-ET operates within -20°C ~ 70°C. The ASE-44.000MHZ-L-C-T extends to -40°C ~ 85°C, making it suitable for extended industrial temperature ranges. Selection depends on specific application temperature requirements.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity? A: MSL 1 indicates the lowest moisture sensitivity level. Both parts have unlimited shelf life under normal storage conditions and do not require special moisture control during handling or storage.
