Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DOC100V-019.44M is determined by the following critical parameters:

• Frequency Match: 19.44 MHz (exact match required)
• Output Configuration: LVCMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Frequency Stability: ±100ppb (exact match required)
• Package Type: 6-SMD, No Lead (exact match required)
• Physical Dimensions: 0.555" L x 0.358" W (exact match required)
• Temperature Range: 0°C ~ 70°C (exact match required)
• Compliance Standards: ROHS3 Compliant, MSL 1 (exact match required)

The DOCAT100V-019.44M qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is the addition of amplitude control functionality and an increased absolute pull range (±10ppm), which represent enhancements rather than deviations from the original specification.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT100V-019.44M is the manufacturer-recommended substitute for the obsolete DOC100V-019.44M. Both parts maintain identical electrical specifications for frequency, output type, supply voltage, and frequency stability. Both components satisfy ROHS3 compliance and carry MSL 1 rating, ensuring equivalent environmental and regulatory compliance.

The DOCAT100V-019.44M introduces amplitude control functionality and specifies an absolute pull range of ±10ppm, representing functional enhancements. The seated height increases from 7.80mm to 8.51mm; this dimensional change requires verification against PCB layout constraints and clearance requirements in the target application.

The active product status of the DOCAT100V-019.44M ensures ongoing availability and manufacturer support, addressing the obsolescence limitation of the original part.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT100V-019.44M be used as a direct replacement for the DOC100V-019.44M?

A: Yes. Both parts share identical frequency (19.44 MHz), output type (LVCMOS), supply voltage (3.3V), frequency stability (±100ppb), package type (6-SMD, No Lead), and physical footprint dimensions (14.10mm x 9.10mm). The DOCAT100V-019.44M is the manufacturer-recommended substitute.

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

A: The DOC100V-019.44M has a maximum seated height of 7.80mm, while the DOCAT100V-019.44M measures 8.51mm. This 0.71mm increase must be evaluated against PCB layout clearances, component stacking requirements, and enclosure constraints in your specific application.

Q: Does the amplitude control feature in the DOCAT100V-019.44M affect compatibility?

A: Amplitude control is an additional feature that does not degrade compatibility. If your circuit design does not utilize this function, the part operates identically to the DOC100V-019.44M in standard applications.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the DOC100V-019.44M and DOCAT100V-019.44M are ROHS3 compliant and carry REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: Why is the DOCAT100V-019.44M recommended over the obsolete DOC100V-019.44M?

A: The DOCAT100V-019.44M maintains active product status with ongoing manufacturer support and availability. The DOC100V-019.44M is obsolete, creating supply chain risk and limiting access to new inventory.
