Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DOC052F-019.44M is determined by strict equivalence across the following critical parameters:

• Frequency: 19.44 MHz (exact match required)
• Output Type: LVCMOS (signal compatibility)
• Supply Voltage: 3.3V (electrical compatibility)
• Frequency Stability: ±50ppb (performance specification)
• Operating Temperature Range: -40°C to 85°C (environmental specification)
• Package / Case: 6-SMD, No Lead (mechanical and thermal compatibility)
• Mounting Type: Surface Mount (assembly compatibility)

The DOCAT052F-019.44M qualifies as a direct substitute based on identical alignment across all critical parameters. The primary distinction is product status: the substitute part is active production, whereas the original is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT052F-019.44M is the manufacturer-recommended substitute for the obsolete DOC052F-019.44M. Both parts maintain identical electrical and mechanical specifications across all critical parameters: frequency, output type, supply voltage, frequency stability, operating temperature range, and package configuration.

The substitute part is in active production status, ensuring long-term availability and supply chain continuity. Both parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

The height difference of 0.028" (0.71mm) between seated heights is within typical PCB assembly tolerances and does not impact functional compatibility or thermal performance in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT052F-019.44M be used as a direct replacement for the DOC052F-019.44M?

A: Yes. The substitute part meets all electrical and mechanical specifications of the original. Frequency, output type, supply voltage, stability, temperature range, and package configuration are identical. The parts are pin-compatible and functionally equivalent.

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

A: The seated height difference of 0.028" (0.71mm) is negligible for standard PCB assembly applications. This variation falls within normal manufacturing tolerances and does not affect electrical performance or thermal management.

Q: Why is the original DOC052F-019.44M classified as obsolete?

A: Obsolescence indicates the part is no longer in active production. The DOCAT052F-019.44M represents the current production equivalent from the same manufacturer, ensuring continued access to this oscillator specification.

Q: Are there packaging differences between the two parts?

A: The main part uses standard packaging, while the substitute is available in Cut Tape (CT) format. Both use the same 6-SMD, No Lead package configuration. Packaging format does not affect component performance or compatibility.

Q: Do both parts meet current compliance standards?

A: Yes. Both the DOC052F-019.44M and DOCAT052F-019.44M are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
