Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and identical compliance certifications (ROHS3 Compliant, REACH Unaffected, MSL 1). Selection between the main part and substitutes depends on application-specific requirements:

ASFL1-32.000MHZ-EK-T is suitable for applications requiring the tightest frequency stability specification at ±30ppm within the standard industrial temperature range of -20°C to 70°C.

ASFL1-32.000MHZ-EC-T provides a mid-range frequency stability of ±50ppm while maintaining the same operating temperature range as the main part, offering increased inventory availability.

ASFL1-32.000MHZ-L-T extends the operating temperature range to -40°C to 85°C with a frequency stability specification of ±100ppm, suitable for applications requiring extended temperature operation or where relaxed frequency stability is acceptable.

All parts are electrically and mechanically interchangeable within their specified parameter ranges and maintain identical power consumption characteristics.

Frequently Asked Questions (FAQ)

Q: Can ASFL1-32.000MHZ-EC-T replace ASFL1-32.000MHZ-EK-T?

A: Yes. Both parts share identical frequency (32 MHz), output type (HCMOS, TTL), supply voltage (3.3V), operating temperature range (-20°C ~ 70°C), and physical package specifications. The difference is frequency stability: EC-T specifies ±50ppm versus EK-T's ±30ppm. This substitution is valid if the application tolerates the wider frequency stability specification.

Q: Can ASFL1-32.000MHZ-L-T replace ASFL1-32.000MHZ-EK-T?

A: Yes. Both parts share identical frequency (32 MHz), output type (HCMOS, TTL), supply voltage (3.3V), and physical package specifications. The L-T variant extends the operating temperature range to -40°C ~ 85°C and specifies ±100ppm frequency stability. This substitution is valid if the application requires the extended temperature range or can accept the relaxed frequency stability specification.

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

A: No. All three parts use identical 4-SMD, No Lead packaging with matching physical dimensions (0.197" L x 0.126" W, 5.00mm x 3.20mm) and maximum seated height (0.051", 1.30mm). Pinout and mounting footprint are identical.

Q: What is the primary difference between these oscillator variants?

A: The primary differences are frequency stability tolerance and operating temperature range. The EK-T offers the tightest frequency stability (±30ppm) in the standard temperature range. The EC-T provides mid-range stability (±50ppm) in the same temperature range. The L-T variant trades tighter stability for extended temperature operation (-40°C ~ 85°C) with ±100ppm stability.

Q: Do all variants have the same power consumption specifications?

A: Yes. All three parts specify identical maximum supply current (45mA) and disable mode current (10µA), ensuring equivalent power consumption characteristics across all variants.

Q: Are all parts ROHS3 compliant?

A: Yes. All three parts are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity level and REACH Unaffected status.
