Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASFL1-1.8432MHZ-EC-T are identified based on the following criteria:

Mandatory Compatibility Parameters:

• Frequency: 1.8432 MHz (exact match required)
• Output Type: HCMOS, TTL (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Package Dimensions: 5.00mm x 3.20mm (exact match required)
• Mounting Type: Surface Mount (exact match required)

Allowable Variation Parameters:

• Frequency Stability: May vary within acceptable tolerance ranges
• Operating Temperature Range: May extend beyond the base part specification
• Maximum Supply Current: Must not exceed 15mA
• Disabled Mode Current: Must not exceed 10µA
• Packaging Format: May differ (bulk vs. Tape & Reel)

The substitute parts ASFL1-1.8432MHZ-EK-T and ASFL1-1.8432MHZ-L-T maintain all mandatory compatibility parameters while offering variations in frequency stability and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

ASFL1-1.8432MHZ-EK-T (Upgrade Substitute): This part offers improved frequency stability at ±30ppm compared to the main part's ±50ppm specification, while maintaining identical electrical and mechanical characteristics. Both parts support the same operating temperature range (-20°C ~ 70°C). This substitute is suitable for applications requiring tighter frequency tolerance. Available in Tape & Reel packaging format.

ASFL1-1.8432MHZ-L-T (MFR Recommended Substitute): This part extends the operating temperature range to -40°C ~ 85°C, providing broader environmental compatibility compared to the main part's -20°C ~ 70°C range. Frequency stability is specified at ±100ppm, which is wider than the main part. This substitute is recommended for applications requiring extended temperature operation. Available in Tape & Reel packaging format.

All three parts maintain Active product status, ROHS3 compliance, and identical electrical performance in terms of supply current, disabled mode current, and output characteristics. Selection between these parts depends on specific application requirements for frequency stability and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ASFL1-1.8432MHZ-EK-T be used as a direct replacement for ASFL1-1.8432MHZ-EC-T?

A: Yes. Both parts share identical frequency, output type, supply voltage, function, and package specifications. The ASFL1-1.8432MHZ-EK-T provides tighter frequency stability (±30ppm vs. ±50ppm) and operates within the same temperature range. No circuit modifications are required.

Q: What is the difference between ASFL1-1.8432MHZ-L-T and the main part?

A: The ASFL1-1.8432MHZ-L-T extends the operating temperature range to -40°C ~ 85°C compared to -20°C ~ 70°C for the main part.
