Key Parameters

Substitute Part Grouping Explanation

Substitution of the DOC020V-019.44M is determined by the following critical parameters:

• Frequency Match: 19.44 MHz (exact)
• Output Configuration: LVCMOS
• Supply Voltage: 3.3V
• Package Type: 6-SMD, No Lead
• Frequency Stability: ±20ppb minimum
• Operating Temperature: 0°C ~ 70°C minimum
• Physical Footprint Compatibility: 14.10mm × 9.10mm base dimensions

The DOCAT020V-019.44M qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The substitute maintains identical frequency, output type, supply voltage, frequency stability, temperature range, and package configuration. Physical height variation (7.80mm vs 8.51mm seated height) remains within acceptable PCB assembly tolerances for 6-SMD, No Lead packages.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT020V-019.44M is qualified as a direct substitute for the DOC020V-019.44M based on the following factors:

• Electrical Equivalence: Identical frequency (19.44 MHz), output type (LVCMOS), supply voltage (3.3V), and frequency stability (±20ppb) ensure functional compatibility in existing circuit designs.
• Mechanical Compatibility: Matching 6-SMD, No Lead package and base footprint dimensions (14.10mm × 9.10mm) permit direct PCB placement without layout modification.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring equivalent environmental and regulatory performance.
• Supply Continuity: The substitute part carries Active product status, providing assured long-term availability compared to the Obsolete original part.

The 0.71mm increase in seated height (7.80mm to 8.51mm) is within standard PCB assembly clearance tolerances for surface mount components and does not require design revision.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT020V-019.44M be used as a direct replacement without PCB modification?
