Substitute Part Grouping Explanation

Substitution eligibility for the ASFL1-100.000MHZ-L-T is determined by the following criteria:

• Frequency match: 100 MHz
• Output compatibility: HCMOS, TTL
• Supply voltage: 3.3V
• Enable/Disable function requirement
• Package and mounting compatibility: 4-SMD, No Lead surface mount
• Physical dimensions: 0.197" L x 0.126" W with maximum seated height of 0.051"
• Compliance certifications: ROHS3, REACH Unaffected, EAR99

The ASFL1-100.000MHZ-EC-T meets all substitution criteria as a manufacturer-recommended equivalent from Abracon LLC within the same ASFL1 series.

Parameter Comparison

Engineering Selection Recommendations

Both the ASFL1-100.000MHZ-L-T and ASFL1-100.000MHZ-EC-T are Active status products from Abracon LLC with identical ROHS3 compliance, REACH Unaffected status, and EAR99 classification. The parts are mechanically and electrically interchangeable for 100 MHz HCMOS/TTL oscillator applications requiring 3.3V supply with enable/disable control in 4-SMD, No Lead surface mount packages.

The ASFL1-100.000MHZ-EC-T offers improved frequency stability at ±50ppm compared to ±100ppm of the ASFL1-100.000MHZ-L-T. The ASFL1-100.000MHZ-L-T provides extended operating temperature range from -40°C to 85°C, while the ASFL1-100.000MHZ-EC-T operates from -20°C to 70°C. Selection between these parts depends on application requirements for temperature range and frequency stability specifications.

Frequently Asked Questions (FAQ)

Q: Can the ASFL1-100.000MHZ-EC-T replace the ASFL1-100.000MHZ-L-T in existing designs?

A: Yes. Both parts share identical package dimensions, pinout, supply voltage, frequency, output type, and enable/disable functionality. Mechanical and electrical compatibility is maintained for PCB assembly and circuit operation.

Q: What are the key differences between these two oscillators?

A: The ASFL1-100.000MHZ-EC-T has tighter frequency stability (±50ppm vs. ±100ppm) but operates over a narrower temperature range (-20°C to 70°C vs. -40°C to 85°C). Select based on your application's temperature and frequency stability requirements.

Q: Are both parts suitable for high-temperature applications?

A: The ASFL1-100.000MHZ-L-T supports operation to 85°C maximum. The ASFL1-100.000MHZ-EC-T is rated to 70°C maximum. For applications requiring operation above 70°C, the ASFL1-100.000MHZ-L-T is the appropriate choice.

Q: Do these oscillators require any special handling or storage considerations?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both the ASFL1-100.000MHZ-L-T and ASFL1-100.000MHZ-EC-T are ROHS3 compliant and REACH Unaffected.
