DOC020V-012.8M VCOCXO Oscillator Equivalent & Substitute Parts

Part Overview

The DOC020V-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 operates across the 0°C to 70°C temperature range with ±20ppb frequency stability and is packaged in a 6-SMD, No Lead format measuring 14.10mm × 9.10mm.

The DOC020V-012.8M is classified as Obsolete. Locating equivalent or substitute components becomes necessary when original inventory is depleted or when design updates require active product lines with enhanced features or improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DOC020V-012.8M is determined by strict alignment across the following critical parameters:

• Frequency: Must be 12.8 MHz (exact match required)
• Output Configuration: Must be LVCMOS
• Supply Voltage: Must be 3.3V
• Frequency Stability: Must be ±20ppb or better
• Operating Temperature Range: Must cover 0°C ~ 70°C minimum
• Package Type: Must be 6-SMD, No Lead
• Physical Footprint: Must be compatible with 14.10mm × 9.10mm land pattern
• Base Resonator: Must be Crystal-based
• Oscillator Type: Must be VCOCXO

The DOCAT020V-012.8M qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The substitute part maintains identical frequency, output type, supply voltage, frequency stability, temperature range, package configuration, and footprint. The substitute part is manufactured by the same supplier (Connor Winfield) and carries Active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT020V-012.8M is the direct substitute for the DOC020V-012.8M based on the following engineering criteria:

Electrical Compatibility: Both parts deliver identical frequency (12.8 MHz), output configuration (LVCMOS), supply voltage (3.3V), and frequency stability (±20ppb). Signal integrity and timing performance remain unchanged in circuit applications.

Mechanical Compatibility: Both parts use the 6-SMD, No Lead package with matching 14.10mm × 9.10mm footprint. The seated height difference (7.80mm vs. 8.51mm) remains within typical PCB assembly tolerances and does not affect placement or clearance in standard designs.

Regulatory and Compliance Status: Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating. No additional qualification or testing is required from a regulatory standpoint.

Product Lifecycle: The DOCAT020V-012.8M carries Active product status, ensuring continued manufacturing, availability, and technical support. This addresses the obsolescence of the original DOC020V-012.8M.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT020V-012.8M be used as a direct replacement for the DOC020V-012.8M without circuit modifications?

A: Yes. Both parts share identical electrical specifications (frequency, output type, supply voltage, and frequency stability) and mechanical compatibility (package type and footprint). No circuit modifications are required.

Q: What is the difference between the DOC020V-012.8M and DOCAT020V-012.8M?

A: The primary difference is product status: the DOC020V-012.8M is Obsolete, while the DOCAT020V-012.8M is Active. The DOCAT series includes Amplitude Control functionality. The seated height differs by 0.71mm (7.80mm vs. 8.51mm), which remains compatible with standard PCB assembly processes.

Q: Are there any compatibility concerns with the height difference between these parts?

A: No. The 0.71mm height difference falls within standard PCB assembly tolerances and does not affect component placement, solder reflow, or clearance in typical circuit board designs.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the DOC020V-012.8M and DOCAT020V-012.8M are ROHS3 compliant, REACH Unaffected, and carry MSL 1 rating. No additional compliance documentation or testing is required for substitution.

Q: Which part should be selected for new designs?

A: The DOCAT020V-012.8M should be selected for new designs due to its Active product status, ensuring long-term availability and manufacturer support.
