Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASFL1-7.3728MHZ-EC-T is determined by strict equivalence across the following critical parameters:

• Frequency: 7.3728 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)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -20°C ~ 70°C (exact match required)
• Physical Dimensions: 5.00mm x 3.20mm x 1.30mm Max (exact match required)

The ASFL1-7.3728MHZ-EK-T qualifies as a direct substitute because it maintains identical specifications across all critical electrical and mechanical parameters. The only variance is in frequency stability (±30ppm versus ±50ppm), which represents an improvement in performance tolerance and does not restrict substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the ASFL1-7.3728MHZ-EC-T and ASFL1-7.3728MHZ-EK-T are Active status products from Abracon LLC within the ASFL1 series. Both parts maintain full ROHS3 compliance, REACH Unaffected status, and identical regulatory classifications (ECCN: EAR99). The substitute part ASFL1-7.3728MHZ-EK-T offers improved frequency stability at ±30ppm compared to the main part's ±50ppm specification, while maintaining all other electrical and mechanical characteristics. Selection between these parts depends on application-specific frequency stability requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ASFL1-7.3728MHZ-EK-T replace ASFL1-7.3728MHZ-EC-T in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters including frequency, output type, supply voltage, package dimensions, and operating temperature range. The substitute part features improved frequency stability, which does not restrict compatibility.

Q: Are there differences in package handling or storage?

A: No. Both parts share identical Moisture Sensitivity Level (MSL 1 - Unlimited) and are supplied in Tape & Reel packaging. Storage and handling procedures are equivalent.

Q: What is the significance of the frequency stability difference?

A: The ASFL1-7.3728MHZ-EK-T provides ±30ppm stability versus ±50ppm for the main part. This represents a tighter tolerance specification and indicates improved frequency accuracy over the operating temperature range.
