DOC100V-012.8M VCOCXO Oscillator Equivalent & Substitute Parts

Part Overview

The DOC100V-012.8M is a 12.8 MHz VCOCXO (Voltage Controlled Crystal Oscillator) with LVCMOS output, designed for 3.3V supply applications in surface mount configurations. This part is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations. The DOC100V-012.8M operates across the 0°C to 70°C temperature range with ±100ppb frequency stability, meeting ROHS3 compliance and REACH unaffected status requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DOC100V-012.8M is determined by strict alignment of the following critical parameters:

• Frequency: 12.8 MHz (exact match required)
• Type: VCOCXO (voltage controlled oscillator functionality)
• Output: LVCMOS (logic voltage compatible output)
• Voltage - Supply: 3.3V (power supply compatibility)
• Frequency Stability: ±100ppb (frequency accuracy specification)
• Operating Temperature: 0°C ~ 70°C (thermal operating range)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Package / Case: 6-SMD, No Lead (footprint and land pattern compatibility)
• Compliance: ROHS3 Compliant, REACH Unaffected (regulatory requirements)

The DOCAT100V-012.8M qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Dimensional variations in height (0.335" vs 0.307") remain within acceptable tolerances for surface mount assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT100V-012.8M is the recommended substitute for the obsolete DOC100V-012.8M. Both parts maintain identical electrical specifications and package footprints, ensuring direct compatibility in existing circuit designs. The DOCAT100V-012.8M carries active product status, providing assured long-term availability and supply chain continuity compared to the obsolete DOC100V-012.8M.

Both parts satisfy ROHS3 compliance and REACH unaffected regulatory requirements, maintaining environmental and safety standards for industrial and commercial applications. The height differential of 0.028" (0.71mm) between the two parts falls within standard surface mount assembly tolerances and does not impact PCB layout or component placement procedures.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT100V-012.8M directly replace the DOC100V-012.8M in existing designs?

A: Yes. Both parts share identical frequency (12.8 MHz), output type (LVCMOS), supply voltage (3.3V), frequency stability (±100ppb), operating temperature range (0°C ~ 70°C), and package configuration (6-SMD, No Lead). The footprint and electrical interface are fully compatible.

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

A: The DOCAT100V-012.8M has a maximum seated height of 0.335" (8.51mm) compared to 0.307" (7.80mm) for the DOC100V-012.8M. This 0.028" (0.71mm) difference is within standard surface mount assembly tolerances and does not affect PCB design, component placement, or reflow soldering processes.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the DOC100V-012.8M and DOCAT100V-012.8M are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations for electronic components.

Q: Why is the DOC100V-012.8M classified as obsolete?

A: The DOC100V-012.8M has reached end-of-life status. The DOCAT100V-012.8M is the active successor product from Connor Winfield, offering the same electrical and mechanical specifications with ongoing manufacturing support and availability.

Q: What is the difference between the DOC and DOCAT series designations?

A: The DOCAT series includes amplitude control functionality as an additional feature. Both series maintain the same core VCOCXO specifications for 12.8 MHz applications. The amplitude control in the DOCAT variant does not affect compatibility with designs using the DOC100V-012.8M.
