Substitute Part Grouping Explanation

The ASFL1-64.000MHZ-L-T is identified as a substitute for the ASFL1-64.000MHZ-EC-T based on the following criteria:

Matching Parameters (Substitution Basis):

• Identical frequency: 64 MHz
• Identical output type: HCMOS, TTL
• Identical supply voltage: 3.3V
• Identical function: Enable/Disable
• Identical package: 4-SMD, No Lead
• Identical mounting type: Surface Mount
• Identical physical dimensions: 0.197" L x 0.126" W (5.00mm x 3.20mm)
• Identical maximum height: 0.051" (1.30mm)
• Identical maximum supply current: 45mA
• Identical disable current: 10µA
• Identical RoHS and REACH compliance status
• Identical MSL rating: 1 (Unlimited)

Differing Parameters:

• Frequency Stability: EC-T variant ±50ppm vs. L-T variant ±100ppm
• Operating Temperature Range: EC-T variant -20°C ~ 70°C vs. L-T variant -40°C ~ 85°C

Parameter Comparison

Engineering Selection Recommendations

Both the ASFL1-64.000MHZ-EC-T and ASFL1-64.000MHZ-L-T are Active status products from Abracon LLC with identical ROHS3 compliance and REACH unaffected status. The L-T variant provides extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C) and relaxed frequency stability specification (±100ppm versus ±50ppm). Selection between these parts depends on application temperature requirements and frequency stability tolerance. Both parts maintain identical electrical performance in supply current, output characteristics, and enable/disable functionality. Physical compatibility is assured through identical package dimensions and mounting specifications.

Frequently Asked Questions (FAQ)

Q: Can ASFL1-64.000MHZ-L-T replace ASFL1-64.000MHZ-EC-T in all applications?

A: Substitution is valid when application operating temperature range does not exceed -20°C ~ 70°C and frequency stability tolerance of ±100ppm is acceptable. The L-T variant supports extended temperature operation to -40°C and 85°C, making it suitable for wider temperature environments.

Q: Are the physical packages identical?

A: Yes. Both parts use 4-SMD, No Lead package with identical dimensions of 0.197" L x 0.126" W (5.00mm x 3.20mm) and maximum height of 0.051" (1.30mm). PCB layout and reflow profiles are compatible.

Q: What is the difference in frequency stability between these parts?

A: The EC-T variant specifies ±50ppm frequency stability, while the L-T variant specifies ±100ppm. Applications requiring tighter frequency tolerance must use the EC-T variant.

Q: Are both parts RoHS compliant?

A: Yes. Both ASFL1-64.000MHZ-EC-T and ASFL1-64.000MHZ-L-T are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What is the operating temperature range for each part?

A: ASFL1-64.000MHZ-EC-T operates from -20°C to 70°C. ASFL1-64.000MHZ-L-T operates from -40°C to 85°C. Select based on application environmental requirements.
