Key Parameters

Substitute Part Grouping Explanation

Substitution for the DOC020F-019.44M is determined by strict equivalence across the following critical parameters:

• Frequency: 19.44 MHz (exact match required)
• Output Type: LVCMOS (logic-level output compatibility)
• Supply Voltage: 3.3V (power supply compatibility)
• Frequency Stability: ±20ppb (timing accuracy specification)
• Operating Temperature Range: 0°C ~ 70°C (thermal operating envelope)
• Package / Case: 6-SMD, No Lead (physical and electrical footprint compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Base Resonator: Crystal (oscillator technology type)
• Type: OCXO (oven-controlled stability class)

The DOCAT020F-019.44M qualifies as a direct substitute based on identical values across all critical parameters. The primary distinction is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging), with negligible physical dimension variance in seated height (8.51mm vs. 7.80mm) that remains within typical PCB assembly tolerances.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT020F-019.44M is the recommended substitute for the obsolete DOC020F-019.44M. Both components maintain identical electrical specifications, frequency accuracy, and thermal operating characteristics. The substitute part carries Active product status, ensuring continued availability and manufacturer support.

Both parts satisfy ROHS3 compliance and REACH regulatory requirements, supporting deployment in regulated applications. The 0.028" (0.71mm) increase in seated height on the substitute part remains within standard PCB assembly clearance tolerances and does not impact circuit board layout or component placement.

The primary advantage of the DOCAT020F-019.44M is its availability in Tape & Reel packaging format, which supports high-volume manufacturing processes and reduces component handling costs in production environments.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT020F-019.44M be used as a direct replacement for the DOC020F-019.44M?

A: Yes. Both parts share identical electrical specifications, frequency output, supply voltage, and thermal operating range. The physical footprint and package type are equivalent, supporting direct PCB substitution without circuit redesign.

Q: What is the significance of the height difference between these parts?

A: The DOC020F-019.44M has a maximum seated height of 0.307" (7.80mm), while the DOCAT020F-019.44M measures 0.335" (8.51mm). This 0.028" (0.71mm) variance is within typical PCB assembly tolerances and does not affect component placement or circuit functionality.

Q: Why is the DOC020F-019.44M classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The DOCAT020F-019.44M, with Active status, represents the current production equivalent and is recommended for new designs and ongoing system support.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both components maintain identical ROHS3 compliance, REACH regulatory status, and EAR99 export classification. Regulatory requirements are satisfied by either part.

Q: What packaging formats are available for these oscillators?

A: The DOC020F-019.44M is available in standard packaging. The DOCAT020F-019.44M is supplied in Tape & Reel (TR) format, which is optimized for automated assembly processes and high-volume production runs.

Q: Are the frequency stability specifications identical?

A: Yes. Both the DOC020F-019.44M and DOCAT020F-019.44M maintain ±20ppb frequency stability across the 0°C to 70°C operating temperature range, ensuring equivalent timing accuracy for system applications.
