Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASFL1-33.3330MHZ-EC-T are qualified based on strict equivalence across the following critical parameters:

• Frequency: 33.333 MHz
• Supply Voltage: 3.3V
• Output Type: HCMOS (TTL compatibility optional)
• Function: Enable/Disable
• Frequency Stability: ±50ppm
• Operating Temperature Range: -20°C ~ 70°C
• Package / Case: 4-SMD, No Lead
• Physical Dimensions: 0.197" L x 0.126" W (5.00mm x 3.20mm)
• Height - Seated (Max): 0.051" (1.30mm)
• Mounting Type: Surface Mount

Two substitute parts meet these criteria: ASFL1-33.333MHZ-EC-T (Abracon LLC) and 636L3C033M33300 (CTS-Frequency Controls). Both maintain identical electrical specifications and mechanical compatibility with the main part.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ASFL1-33.3330MHZ-EC-T, ASFL1-33.333MHZ-EC-T, and 636L3C033M33300—are Active status components with ROHS3 compliance and MSL 1 rating. Selection between them is determined by supply chain availability and packaging preference (Tape & Reel vs. standard packaging). The CTS-Frequency Controls 636L3C033M33300 offers lower maximum supply current (16mA vs. 45mA), which may provide power efficiency benefits in applications where current consumption is a design constraint. Both Abracon LLC parts are functionally identical with TTL output compatibility explicitly specified.

Frequently Asked Questions (FAQ)

Q: Can the 636L3C033M33300 directly replace the ASFL1-33.3330MHZ-EC-T?

A: Yes. Both parts share identical frequency (33.333 MHz), supply voltage (3.3V), output type (HCMOS), enable/disable function, frequency stability (±50ppm), operating temperature range (-20°C ~ 70°C), and physical dimensions (5.00mm x 3.20mm, 1.30mm height). The 636L3C033M33300 specifies HCMOS output only, while the ASFL1-33.3330MHZ-EC-T includes TTL compatibility. If TTL output is required, use the ASFL1 series.

Q: What is the difference between ASFL1-33.3330MHZ-EC-T and ASFL1-33.333MHZ-EC-T?

A: These are equivalent Abracon LLC parts differing only in packaging format. ASFL1-33.3330MHZ-EC-T is supplied in standard packaging, while ASFL1-33.333MHZ-EC-T is supplied in Tape & Reel (TR) format. Electrical and mechanical specifications are identical.

Q: Does the lower current consumption of the 636L3C033M33300 affect performance?

A: No. The 636L3C033M33300 operates within the same frequency stability (±50ppm) and temperature range (-20°C ~ 70°C) as the ASFL1 series. The lower maximum supply current (16mA vs. 45mA) reflects the device's power efficiency characteristics and does not impact frequency accuracy or output compatibility.

Q: Are all three parts suitable for high-reliability applications?

A: Yes. All three parts are Active status, ROHS3 compliant, and carry MSL 1 (Unlimited) moisture sensitivity rating, indicating suitability for standard industrial and commercial applications.

Q: What packaging options are available?

A: The ASFL1-33.3330MHZ-EC-T is available in standard packaging. The ASFL1-33.333MHZ-EC-T and 636L3C033M33300 are supplied in Tape & Reel (TR) format for automated assembly processes.
