Key Parameters

Substitute Part Grouping Explanation

Substitution of the DOC102V-019.44M is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 19.44 MHz
• Output Type: LVCMOS
• Supply Voltage: 3.3V
• Package Type: 6-SMD, No Lead
• Base Resonator: Crystal
• Type: VCOCXO
• Frequency Stability: ±100ppb
• Operating Temperature Range: -40°C to 85°C

Allowable Variations:

• Function: Additional features such as amplitude control are permissible
• Absolute Pull Range (APR): Presence of specified APR is acceptable
• Height - Seated (Max): Minor dimensional variations within assembly constraints are acceptable
• Product Status: Active status parts are preferred for obsolete components

The DOCAT102V-019.44M qualifies as a direct substitute based on identical core electrical specifications and compatible mechanical packaging.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT102V-019.44M is the recommended substitute for the obsolete DOC102V-019.44M. Both parts maintain identical electrical specifications for frequency, output type, supply voltage, and frequency stability. The substitute part carries Active product status, ensuring continued availability and manufacturing support.

Both parts comply with ROHS3 and REACH requirements, maintaining equivalent environmental and regulatory compliance. The substitute part includes amplitude control functionality and specifies an Absolute Pull Range of ±10ppm, which represents enhanced capability without compromising compatibility.

The height difference of 0.028" (0.71mm) between the seated maximum dimensions is within typical PCB assembly tolerances for surface mount components and does not present mechanical compatibility issues for standard board designs.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT102V-019.44M directly replace the DOC102V-019.44M in existing designs?

A: Yes. Both parts share identical frequency, output type, supply voltage, frequency stability, operating temperature range, and package footprint. The substitute part is mechanically and electrically compatible.

Q: What is the significance of the amplitude control function in the DOCAT102V-019.44M?

A: Amplitude control is an additional feature that does not affect core oscillator functionality. Designs utilizing only standard VCOCXO operation will function identically with or without this feature present.

Q: Does the height difference between parts affect PCB assembly?

A: The 0.028" (0.71mm) height increase falls within standard surface mount assembly tolerances and does not require PCB redesign for typical applications.

Q: Why is the DOCAT102V-019.44M classified as Active while the original is Obsolete?

A: The DOCAT series represents the current production line for this frequency and specification set. Connor Winfield has transitioned manufacturing to the DOCAT series, making it the supported option for new and ongoing applications.

Q: Are RoHS and REACH compliance identical between both parts?

A: Yes. Both parts maintain ROHS3 Compliant status and REACH Unaffected classification, ensuring equivalent environmental and regulatory compliance.

Q: What does the ±10ppm Absolute Pull Range specification mean for the substitute part?

A: The APR defines the frequency adjustment range available through the control voltage input. This specification is present in the substitute but not specified in the original part, representing additional documented capability.
