Parameter Comparison

Engineering Selection Recommendations

All three parts—ASFL1-32.000MHZ-L-T, ASFL1-32.000MHZ-EC-T, and ASFL1-32.000MHZ-EK-T—are Active status products from Abracon LLC with ROHS3 Compliance and REACH Unaffected status. They share identical electrical and mechanical specifications for frequency, output type, supply voltage, current consumption, package dimensions, and mounting characteristics.

Selection between these parts depends on application-specific requirements:

ASFL1-32.000MHZ-L-T is suitable for applications requiring extended operating temperature range from -40°C to 85°C with standard frequency stability of ±100ppm.

ASFL1-32.000MHZ-EC-T provides improved frequency stability of ±50ppm with operating temperature range of -20°C to 70°C, appropriate for applications with moderate temperature constraints and tighter frequency tolerance requirements.

ASFL1-32.000MHZ-EK-T offers the highest frequency stability of ±30ppm with operating temperature range of -20°C to 70°C, suitable for applications demanding superior frequency accuracy within the specified temperature window.

All parts maintain identical compliance certifications, moisture sensitivity ratings, and supply current characteristics, ensuring direct substitution capability within the defined parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can ASFL1-32.000MHZ-EC-T or ASFL1-32.000MHZ-EK-T be used as direct replacements for ASFL1-32.000MHZ-L-T?

A: Yes, both substitute parts are direct replacements from an electrical and mechanical standpoint. They share identical frequency, output type, supply voltage, current consumption, package dimensions, and mounting characteristics. The differences lie in frequency stability and operating temperature range, which may be advantageous depending on application requirements.

Q: What is the key difference between the three parts?

A: The primary differences are frequency stability and operating temperature range. ASFL1-32.000MHZ-L-T offers ±100ppm stability across -40°C to 85°C. ASFL1-32.000MHZ-EC-T provides ±50ppm stability across -20°C to 70°C. ASFL1-32.000MHZ-EK-T delivers ±30ppm stability across -20°C to 70°C. All other electrical and mechanical parameters remain identical.

Q: Are there any package or footprint differences between these parts?

A: No. All three parts use the identical 4-SMD, No Lead package with dimensions of 5.00mm x 3.20mm and maximum seated height of 1.30mm. PCB footprints and assembly processes are interchangeable.

Q: Which part should I select if my application operates across the full -40°C to 85°C temperature range?

A: ASFL1-32.000MHZ-L-T is the appropriate choice for applications requiring the extended temperature range from -40°C to 85°C. The substitute parts are rated only to -20°C to 70°C and would not be suitable for applications exceeding these limits.

Q: Which part offers the best frequency stability?

A: ASFL1-32.000MHZ-EK-T provides the tightest frequency stability specification at ±30ppm, followed by ASFL1-32.000MHZ-EC-T at ±50ppm, and ASFL1-32.000MHZ-L-T at ±100ppm. Selection should be based on the frequency accuracy requirements of your specific application.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant with REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these oscillators?

A: All three parts have Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
