DOC052V-012.8M Equivalent & Substitute Parts

Part Overview

The DOC052V-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 oscillator operates across the industrial temperature range of -40°C to 85°C with frequency stability of ±50ppb. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DOC052V-012.8M is determined by strict equivalence across the following critical parameters:

• Frequency: 12.8 MHz (exact match required)
• Output Type: LVCMOS (logic family compatibility)
• Supply Voltage: 3.3V (power supply compatibility)
• Frequency Stability: ±50ppb (timing accuracy specification)
• Operating Temperature Range: -40°C to 85°C (thermal operating envelope)
• Package / Case: 6-SMD, No Lead (PCB footprint compatibility)
• Base Resonator: Crystal (oscillator technology type)
• Type: VCOCXO (voltage control capability)

The DOCAT052V-012.8M qualifies as a direct substitute based on identical values across all critical parameters. The primary distinction is the product status transition from obsolete to active, and packaging format change from standard to Tape & Reel (TR).

Engineering Selection Recommendations

The DOCAT052V-012.8M is the manufacturer-recommended substitute for the obsolete DOC052V-012.8M. Selection of this substitute is supported by:

• Active Product Status: The DOCAT052V-012.8M maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.
• Electrical Equivalence: All critical electrical parameters—frequency, output type, supply voltage, and frequency stability—are identical, ensuring functional compatibility in existing circuit designs.
• Mechanical Compatibility: The 6-SMD, No Lead package and footprint dimensions remain unchanged, allowing direct PCB layout reuse without redesign.
• Height Variance: The seated height difference of 0.028" (0.71mm) is within acceptable mechanical tolerances for surface mount assembly and does not impact circuit performance or board clearance in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT052V-012.8M be used as a direct replacement for the DOC052V-012.8M?

A: Yes. The DOCAT052V-012.8M is electrically and mechanically equivalent across all critical parameters. The primary differences are product status (active vs. obsolete) and packaging format (Tape & Reel vs. standard). Both support identical circuit functionality.

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

A: The DOC052V-012.8M has a maximum seated height of 0.307" (7.80mm), while the DOCAT052V-012.8M measures 0.335" (8.51mm). This 0.028" (0.71mm) variance is within standard surface mount assembly tolerances and does not affect electrical performance or typical PCB clearance requirements.

Q: Why is the DOC052V-012.8M classified as obsolete?

A: Obsolescence indicates the part is no longer in active production. The DOCAT052V-012.8M represents the active successor in the Connor Winfield product line, maintaining identical electrical and mechanical specifications.

Q: Are there packaging considerations when switching from DOC052V-012.8M to DOCAT052V-012.8M?

A: The DOC052V-012.8M is supplied in standard packaging, while the DOCAT052V-012.8M is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume production and automated assembly. Both formats contain identical components with no functional difference.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the DOC052V-012.8M and DOCAT052V-012.8M are ROHS3 compliant, REACH unaffected, and carry identical environmental certifications. They satisfy equivalent regulatory requirements for industrial and commercial applications.

Q: What is the frequency stability specification, and why is it important?

A: Both parts specify ±50ppb (parts per billion) frequency stability across the -40°C to 85°C operating range. This specification defines the maximum deviation from the nominal 12.8 MHz frequency and is critical for timing-sensitive applications requiring precise clock references.
