DOC050V-019.44M VCOCXO Oscillator Equivalent & Substitute Parts

Part Overview

The DOC050V-019.44M is a 19.44 MHz VCOCXO (Voltage Controlled Crystal Oscillator) with LVCMOS output, designed for 3.3V supply applications in surface mount configurations. This part operates across the 0°C to 70°C temperature range with ±50ppb frequency stability and is packaged in a 6-SMD, No Lead format measuring 14.10mm × 9.10mm.

The DOC050V-019.44M carries an Obsolete product status. Locating equivalent or substitute components becomes necessary when original inventory is depleted or when design continuity requires active production alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DOC050V-019.44M is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 19.44 MHz (exact match required)
• Output Type: LVCMOS (electrical interface compatibility)
• Supply Voltage: 3.3V (power supply compatibility)
• Frequency Stability: ±50ppb (timing accuracy specification)
• Operating Temperature Range: 0°C ~ 70°C (thermal operating envelope)
• Package / Case: 6-SMD, No Lead (PCB footprint compatibility)
• Physical Dimensions: 14.10mm L × 9.10mm W (board layout fit)

Allowable Variation Parameters:

• Maximum Seated Height: Substitute parts may exceed the original 7.80mm specification provided the increased height does not create mechanical interference in the target application
• Additional Functions: Substitute parts may include supplementary features (such as Amplitude Control) that do not conflict with the original design intent
• Absolute Pull Range (APR): Substitute parts may include APR specifications where the original part does not define this parameter

The DOCAT050V-019.44M qualifies as a direct substitute based on full alignment with all mandatory matching parameters and allowable variations in supplementary specifications.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT050V-019.44M is the manufacturer-recommended substitute for the obsolete DOC050V-019.44M. Both parts maintain identical electrical specifications across frequency, output type, supply voltage, and frequency stability. Both comply with ROHS3 and REACH regulatory requirements and carry the same ECCN classification.

The DOCAT050V-019.44M carries Active product status, ensuring ongoing availability and manufacturing support. The addition of Amplitude Control functionality and the defined ±10ppm Absolute Pull Range represent enhancements that do not degrade compatibility with designs originally specified for the DOC050V-019.44M.

The increase in maximum seated height from 7.80mm to 8.51mm (0.71mm differential) must be evaluated against the specific PCB assembly clearance envelope of the target application. In standard surface mount configurations with typical component spacing, this height increase presents no functional constraint.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT050V-019.44M be used as a direct replacement for the DOC050V-019.44M without PCB modifications?

A: Yes, provided the PCB assembly clearance accommodates the increased maximum seated height of 8.51mm. The identical footprint (6-SMD, No Lead, 14.10mm × 9.10mm) and electrical specifications ensure functional compatibility. Verify clearance above the component location to confirm no mechanical interference exists.

Q: What is the significance of the Amplitude Control function added in the DOCAT050V-019.44M?

A: Amplitude Control is a supplementary feature that does not conflict with applications designed for the original DOC050V-019.44M. This feature provides additional design flexibility for applications requiring output amplitude adjustment but does not mandate its use in existing designs.

Q: How does the ±10ppm Absolute Pull Range specification affect substitution compatibility?

A: The APR specification defines the frequency tuning range available through the control voltage input. The original DOC050V-019.44M does not specify an APR value. The DOCAT050V-019.44M's ±10ppm APR provides a defined tuning capability that enhances design flexibility without creating incompatibility with the original specification.

Q: Are there any regulatory or compliance differences between these parts?

A: No. Both parts carry identical RoHS3 Compliant, REACH Unaffected, and EAR99 ECCN classifications. Regulatory and compliance status is equivalent.

Q: What is the inventory status of these parts?

A: The DOC050V-019.44M (Obsolete) has 952 pieces in stock. The DOCAT050V-019.44M (Active) has 930 pieces in stock. The Active status of the substitute ensures continued availability for future production requirements.
