Substitute Part Grouping Explanation

Substitution eligibility for the ASFL1-30.000MHZ-EC-T is determined by strict alignment of the following critical parameters:

• Frequency: 30 MHz (exact match required)
• Output Configuration: 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)
• Maximum Height: 1.30mm (exact match required)
• Mounting Type: Surface Mount (exact match required)

Parameters that may vary within acceptable substitution criteria:

• Frequency Stability: ±50ppm to ±100ppm
• Operating Temperature Range: -20°C ~ 70°C to -40°C ~ 85°C
• Supply Current (Max): 45mA (consistent across variants)
• Disable Current (Max): 10µA (consistent across variants)

The ASFL1-30.000MHZ-L-T qualifies as a direct substitute based on identical frequency, output type, voltage, function, and physical package specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ASFL1-30.000MHZ-EC-T and ASFL1-30.000MHZ-L-T are Active status products from Abracon LLC, maintaining identical ROHS3 compliance and REACH Unaffected certifications. Selection between these parts should be based on application-specific requirements:

The ASFL1-30.000MHZ-EC-T offers tighter frequency stability at ±50ppm with a narrower operating temperature range of -20°C ~ 70°C, suitable for applications with moderate temperature variation and stringent frequency accuracy requirements.

The ASFL1-30.000MHZ-L-T provides extended operating temperature range of -40°C ~ 85°C with ±100ppm frequency stability, appropriate for applications requiring broader thermal operation or where relaxed frequency tolerance is acceptable.

Both parts maintain identical electrical performance characteristics including 45mA maximum supply current and 10µA disable current, ensuring functional interchangeability in circuit design.

Frequently Asked Questions (FAQ)

Q: Can ASFL1-30.000MHZ-L-T replace ASFL1-30.000MHZ-EC-T in existing designs?

A: Yes. Both parts share identical frequency (30 MHz), output configuration (HCMOS, TTL), supply voltage (3.3V), enable/disable function, and physical package specifications (4-SMD, No Lead, 5.00mm x 3.20mm, 1.30mm height). Electrical performance parameters including supply current and disable current are identical.

Q: What are the differences between these substitute parts?

A: The primary differences are frequency stability tolerance and operating temperature range. The ASFL1-30.000MHZ-EC-T specifies ±50ppm stability over -20°C ~ 70°C, while the ASFL1-30.000MHZ-L-T specifies ±100ppm stability over -40°C ~ 85°C. Selection depends on application temperature requirements and frequency accuracy specifications.

Q: Are both parts surface mount compatible with the same PCB footprint?

A: Yes. Both parts use identical 4-SMD, No Lead package type with matching dimensions of 5.00mm x 3.20mm and maximum seated height of 1.30mm, ensuring PCB footprint compatibility without design modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ASFL1-30.000MHZ-EC-T and ASFL1-30.000MHZ-L-T are ROHS3 Compliant, REACH Unaffected, and carry MSL Rating 1 (Unlimited), meeting identical environmental and regulatory requirements.

Q: Which part should be selected for extended temperature applications?

A: The ASFL1-30.000MHZ-L-T is specified for -40°C ~ 85°C operation, providing extended temperature range compared to the ASFL1-30.000MHZ-EC-T (-20°C ~ 70°C). Selection should align with application thermal requirements.
