DOC100F-019.44M OCXO Oscillator Equivalent & Substitute Parts

Part Overview

The DOC100F-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 ±100ppb frequency stability and is packaged in a 6-SMD, No Lead surface mount configuration.

The DOC100F-019.44M has reached obsolete product status. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for existing applications or new designs requiring this frequency and output specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DOC100F-019.44M is determined by strict alignment 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: ±100ppb (exact match required)
• Operating Temperature Range: 0°C ~ 70°C (exact match required)
• Package / Case: 6-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The DOCAT100F-019.44M meets all substitution criteria. Both components share identical electrical specifications, frequency output, supply requirements, and environmental operating parameters. The primary difference is product status: the DOC100F-019.44M is obsolete, while the DOCAT100F-019.44M is active production.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT100F-019.44M is the direct substitute for the obsolete DOC100F-019.44M. Both components are manufactured by Connor Winfield and maintain identical electrical and functional specifications across all critical parameters.

Selection of the DOCAT100F-019.44M is supported by:

• Active product status ensuring ongoing availability and supply chain support
• Full compliance with ROHS3 and REACH regulatory requirements
• Identical frequency, output type, supply voltage, and stability specifications
• Compatible surface mount package and footprint
• Unlimited moisture sensitivity rating (MSL 1)

The maximum seated height difference of 0.028" (0.71mm) between the two variants is within typical PCB design tolerances for 6-SMD surface mount components and does not impact electrical performance or circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT100F-019.44M be used as a direct replacement for the DOC100F-019.44M?

A: Yes. Both components share identical electrical specifications, frequency output, supply voltage, operating temperature range, and package configuration. The DOCAT100F-019.44M is the active production equivalent.

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

A: The DOC100F-019.44M has a maximum seated height of 0.307" (7.80mm), while the DOCAT100F-019.44M measures 0.335" (8.51mm). This 0.028" (0.71mm) difference is within standard PCB design clearances for surface mount components and does not affect electrical performance or circuit compatibility.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the DOC100F-019.44M and DOCAT100F-019.44M are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What are the critical parameters for substitution?

A: Substitution requires exact matching of frequency (19.44 MHz), output type (LVCMOS), supply voltage (3.3V), frequency stability (±100ppb), operating temperature range (0°C ~ 70°C), package type (6-SMD, No Lead), and compliance certifications (ROHS3).

Q: Is the DOCAT100F-019.44M available in production quantities?

A: Yes. The DOCAT100F-019.44M is an active product with current manufacturing support, ensuring reliable supply availability compared to the obsolete DOC100F-019.44M.
