Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DOC052V-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
• Physical Footprint: 0.555" L x 0.358" W (14.10mm x 9.10mm)
• Frequency Stability: ±50ppb minimum
• Operating Temperature: -40°C ~ 85°C minimum
• Compliance: ROHS3 Compliant, REACH Unaffected

The DOCAT052V-019.44M meets all substitution criteria. Both parts share identical frequency, output type, supply voltage, package configuration, and footprint dimensions. The substitute maintains equivalent frequency stability and operating temperature specifications while offering active product status.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT052V-019.44M is the qualified substitute for the DOC052V-019.44M. Both parts are manufactured by Connor Winfield and maintain identical electrical specifications, frequency output, and package footprint. The substitute part carries active product status, ensuring continued availability and manufacturing support.

The DOCAT052V-019.44M includes amplitude control functionality not present in the original part. The maximum seated height differs by 0.028" (0.71mm), which must be evaluated against specific PCB clearance requirements in the target application.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT052V-019.44M directly replace the DOC052V-019.44M in existing designs?

A: Yes, for applications where the additional 0.028" (0.71mm) height increase does not conflict with PCB clearance constraints. The electrical specifications, frequency output, supply voltage, and package footprint are identical.

Q: What is the significance of the amplitude control feature in the DOCAT052V-019.44M?

A: Amplitude control is an additional functional capability in the substitute part. This feature does not affect compatibility with designs that do not utilize it.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory standards.

Q: What is the Absolute Pull Range (APR) specification?

A: The APR for the DOCAT052V-019.44M is ±10ppm. This parameter was not specified for the DOC052V-019.44M in the provided data.

Q: How does the frequency stability of ±50ppb affect oscillator selection?

A: Frequency stability of ±50ppb defines the maximum frequency deviation across the operating temperature range and supply voltage variations. Both parts meet this specification identically.
