DOC050F-019.44M Equivalent & Substitute Parts

Part Overview

The DOC050F-019.44M is a 19.44 MHz OCXO (Oven Controlled Crystal Oscillator) with LVCMOS output, designed for applications requiring stable frequency generation at 3.3V supply voltage. This component operates across the 0°C to 70°C temperature range with ±50ppb frequency stability and is housed in a compact 6-SMD, No Lead surface mount package.

The DOC050F-019.44M carries an Obsolete product status. Identifying equivalent substitute parts is essential for ongoing system support, design updates, and procurement continuity when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the DOC050F-019.44M is determined by strict equivalence across the following critical parameters:

• Frequency: 19.44 MHz (exact match required)
• Output Type: LVCMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Frequency Stability: ±50ppb (exact match required)
• Operating Temperature Range: 0°C ~ 70°C (exact match required)
• Package / Case: 6-SMD, No Lead (exact match required)
• Physical Dimensions: 0.555" L x 0.358" W (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (exact match required)

The DOCAT050F-019.44M meets all substitution criteria. This part maintains identical electrical specifications and physical form factor while offering Active product status and improved availability through Tape & Reel packaging.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT050F-019.44M is the direct equivalent substitute for the DOC050F-019.44M. Both parts are manufactured by Connor Winfield and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product lifecycle status: the DOC050F-019.44M is Obsolete, while the DOCAT050F-019.44M carries Active status. The substitute part is available in Tape & Reel packaging, which provides advantages for automated assembly and supply chain continuity.

The seated height difference of 0.028" (0.71mm) between the two parts is within typical PCB design tolerances for surface mount components and does not affect functional compatibility or board-level integration.

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT050F-019.44M be used as a direct replacement for the DOC050F-019.44M?

A: Yes. The DOCAT050F-019.44M is electrically and mechanically equivalent. All critical parameters—frequency, output type, supply voltage, frequency stability, operating temperature range, package type, and physical dimensions—are identical. The parts are interchangeable at the circuit level.

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

A: The DOC050F-019.44M has a maximum seated height of 0.307" (7.80mm), while the DOCAT050F-019.44M measures 0.335" (8.51mm). This 0.028" (0.71mm) difference is within standard PCB design clearance margins for surface mount components and does not impact functional performance or board-level compatibility.

Q: Why is the DOC050F-019.44M listed as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this part number. The DOCAT050F-019.44M, with Active status, represents the current production equivalent and is the recommended selection for new designs and ongoing procurement.

Q: What is the difference between bulk and Tape & Reel packaging?

A: The DOC050F-019.44M is supplied in bulk packaging, while the DOCAT050F-019.44M is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly processes and provides improved handling and traceability throughout the supply chain.

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

A: No. Both parts maintain identical RoHS3 compliance and REACH Unaffected status. They meet the same regulatory requirements for current manufacturing and environmental standards.
