Key Parameters

Substitute Part Grouping Explanation

Substitution for the ASFL1-3.6864MHZ-EC-T is limited to parts within the ASFL1 series that maintain identical electrical and mechanical specifications. The critical parameters that determine substitutability are:

• Frequency: 3.6864 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 / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 0.197" L x 0.126" W, Height 0.051" max (exact match required)
• Mounting Type: Surface Mount (exact match required)

Variations in frequency stability, operating temperature range, and supply current are permitted within the ASFL1 series, provided all other parameters remain identical. The substitute part ASFL1-3.6864MHZ-L-T meets these criteria.

Parameter Comparison

Engineering Selection Recommendations

Both the ASFL1-3.6864MHZ-EC-T and ASFL1-3.6864MHZ-L-T are Active status components manufactured by Abracon LLC and are ROHS3 Compliant with REACH Unaffected status. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating and are suitable for direct substitution in applications where the specified electrical and mechanical parameters are met.

The ASFL1-3.6864MHZ-L-T substitute offers an extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C) and wider frequency stability tolerance (±100ppm versus ±50ppm). Selection between these parts depends on application-specific temperature and frequency stability requirements. Both parts are identical in package, dimensions, supply voltage, output type, and current consumption specifications.

Frequently Asked Questions (FAQ)

Q: Can ASFL1-3.6864MHZ-L-T be used as a direct replacement for ASFL1-3.6864MHZ-EC-T?

A: Yes, the ASFL1-3.6864MHZ-L-T is a direct substitute. Both parts share identical frequency, output type, supply voltage, enable/disable function, package configuration, and physical dimensions. The substitute part operates across a wider temperature range and has a broader frequency stability tolerance.

Q: What are the differences between these two parts?

A: The primary differences are frequency stability tolerance and operating temperature range. The main part specifies ±50ppm stability over -20°C ~ 70°C, while the substitute specifies ±100ppm stability over -40°C ~ 85°C. All other electrical and mechanical parameters are identical.

Q: Are both parts available in the same packaging format?

A: Yes. Both ASFL1-3.6864MHZ-EC-T and ASFL1-3.6864MHZ-L-T are supplied in Tape & Reel (TR) packaging and feature identical 4-SMD, No Lead surface mount packages with matching physical dimensions of 5.00mm x 3.20mm and maximum seated height of 1.30mm.

Q: Which part should I select for my application?

A: Selection is based on application requirements. If your circuit operates within -20°C ~ 70°C and requires ±50ppm frequency stability, either part is suitable. If your application requires extended temperature operation (-40°C ~ 85°C) or can tolerate ±100ppm stability, the ASFL1-3.6864MHZ-L-T is appropriate. Both parts are Active status with full compliance certifications.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical MSL 1 (Unlimited) ratings. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.
