DOC050V-012.8M VCOCXO Oscillator Equivalent & Substitute Parts

Part Overview

The DOC050V-012.8M is a 12.8 MHz VCOCXO (Voltage Controlled Crystal Oscillator) with LVCMOS output, designed for 3.3V supply applications. This oscillator operates across the 0°C to 70°C temperature range with ±50ppb frequency stability. 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 eligibility for the DOC050V-012.8M is determined by the following critical parameters:

• Frequency Match: 12.8 MHz (exact match required)
• Output Configuration: LVCMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Frequency Stability: ±50ppb (minimum requirement)
• Package Type: 6-SMD, No Lead (exact match required)
• Physical Footprint: 0.555" L x 0.358" W (exact match required)
• Operating Temperature: 0°C ~ 70°C (minimum requirement)
• Compliance: ROHS3 Compliant, MSL 1

The DOCAT050V-012.8M qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The addition of amplitude control functionality and the ±10ppm absolute pull range represent enhancements that do not compromise compatibility with existing designs.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT050V-012.8M is the manufacturer-recommended substitute for the obsolete DOC050V-012.8M. Both parts maintain identical electrical specifications for frequency, output type, supply voltage, and frequency stability. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The maximum seated height difference of 0.028" (0.71mm) between the main part and substitute must be evaluated within the context of specific PCB layout constraints. Both parts maintain ROHS3 compliance and MSL 1 rating, supporting equivalent environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT050V-012.8M be used as a direct replacement for the DOC050V-012.8M?

A: Yes. Both parts share identical frequency (12.8 MHz), output type (LVCMOS), supply voltage (3.3V), frequency stability (±50ppb), package configuration (6-SMD, No Lead), and physical footprint (0.555" L x 0.358" W). The substitute is the manufacturer-recommended alternative.

Q: What is the significance of the amplitude control function in the DOCAT050V-012.8M?

A: Amplitude control is an additional feature in the substitute part that does not affect basic oscillator operation. Existing designs that do not utilize this function will operate identically to the original part.

Q: Does the height difference between parts affect PCB compatibility?

A: The DOCAT050V-012.8M has a maximum seated height of 0.335" (8.51mm) compared to 0.307" (7.80mm) for the DOC050V-012.8M. This 0.028" (0.71mm) difference must be verified against specific PCB clearance requirements and component placement constraints in your design.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the DOC050V-012.8M and DOCAT050V-012.8M are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) ratings.

Q: What is the absolute pull range specification?

A: The DOCAT050V-012.8M specifies an absolute pull range of ±10ppm, which defines the frequency adjustment range available through the control voltage input. The original DOC050V-012.8M does not specify this parameter.
