Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ASFL-3.6864MHZ is based on the following critical parameters:

Frequency Match: The substitute part must operate at the identical frequency of 3.6864 MHz to ensure direct functional replacement without circuit redesign.

Manufacturer Continuity: Abracon LLC manufactures both the original and substitute part, ensuring consistent design philosophy, quality standards, and technical support.

Compliance Alignment: Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating, ensuring regulatory and environmental compatibility.

Base Resonator Type: Both parts utilize crystal-based resonators, maintaining the same oscillation mechanism and stability characteristics.

The ASFL1-3.6864MHZ-L-T is the direct active equivalent, offering the same frequency output with enhanced product status and documented electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ASFL1-3.6864MHZ-L-T is the appropriate substitute for the obsolete ASFL-3.6864MHZ based on the following factors:

Product Status Transition: The ASFL1-3.6864MHZ-L-T maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH Unaffected status, eliminating regulatory risk in substitution.

Moisture Sensitivity Consistency: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage, handling, or assembly.

Frequency Precision: The identical 3.6864 MHz frequency specification ensures direct functional equivalence without circuit modification or system recalibration.

Manufacturer Support: Abracon LLC's continued production of the ASFL1 series provides access to current technical documentation, quality assurance, and customer support resources.
