Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASFL-33.000MHZ is based on the following critical parameters:

Frequency Match: The substitute part must operate at 33.000 MHz to maintain circuit timing specifications and system compatibility.

Manufacturer Continuity: Abracon LLC manufactures both the original and substitute part, ensuring consistent design philosophy and performance characteristics.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for the same application environments.

Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) rating, indicating equivalent moisture handling and storage requirements.

The ASFL1-33.000MHZ-EK-T is identified as the direct substitute for the obsolete ASFL-33.000MHZ. This substitute maintains the 33 MHz frequency specification while transitioning to an active product status with enhanced specifications including defined output characteristics (HCMOS, TTL), supply voltage (3.3V), and frequency stability (±30ppm).

Engineering Selection Recommendations

The ASFL1-33.000MHZ-EK-T is the designated substitute for the obsolete ASFL-33.000MHZ based on the following engineering criteria:

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying identical regulatory requirements for deployment in equivalent application environments.

Product Lifecycle Status: The ASFL1-33.000MHZ-EK-T carries active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity. The original ASFL-33.000MHZ is obsolete and subject to discontinuation of support and inventory depletion.

Frequency Specification: The substitute maintains the 33 MHz frequency requirement, preserving circuit timing and system synchronization specifications.

Moisture Handling: Both components carry MSL 1 (Unlimited) rating, indicating equivalent moisture sensitivity classification and identical storage and handling protocols.

Selection of the ASFL1-33.000MHZ-EK-T for replacement applications is supported by regulatory alignment, frequency equivalence, and active product status.
