DOC050V-020.0M VCOCXO Oscillator Equivalent & Substitute Parts

Part Overview

The DOC050V-020.0M is a 20 MHz VCOCXO (Voltage Controlled Crystal Oscillator) with LVCMOS output, designed for 3.3V supply applications. This component operates across the 0°C to 70°C temperature range and delivers ±50ppb frequency stability. The part is classified as obsolete, making identification of active equivalent components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The DOCAT050V-020.0M qualifies as a direct substitute for the DOC050V-020.0M based on the following critical parameters:

Matching Parameters:

• Frequency: 20 MHz (identical)
• Output Type: LVCMOS (identical)
• Supply Voltage: 3.3V (identical)
• Frequency Stability: ±50ppb (identical)
• Operating Temperature Range: 0°C ~ 70°C (identical)
• Base Resonator: Crystal (identical)
• Oscillator Type: VCOCXO (identical)
• Package / Case: 6-SMD, No Lead (identical)
• Physical Dimensions: 0.555" L x 0.358" W / 14.10mm x 9.10mm (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
• REACH Status: REACH Unaffected (identical)

Distinguishing Factors:

• Product Status: DOCAT050V-020.0M is Active (vs. Obsolete for DOC050V-020.0M)
• Packaging: DOCAT050V-020.0M supplied in Tape & Reel (TR) format
• Absolute Pull Range (APR): DOCAT050V-020.0M specifies ±15ppm
• Height - Seated (Max): DOCAT050V-020.0M measures 0.335" (8.51mm) vs. 0.307" (7.80mm) for DOC050V-020.0M

Parameter Comparison

Engineering Selection Recommendations

The DOCAT050V-020.0M is the manufacturer-recommended substitute for the obsolete DOC050V-020.0M. Both components maintain identical electrical specifications across frequency, output type, supply voltage, and frequency stability parameters. The DOCAT series represents the active production line continuation from the DOC series.

Selection of DOCAT050V-020.0M is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Full ROHS3 compliance and REACH unaffected status matching the original part
• Identical MSL rating (1 - Unlimited) eliminating moisture sensitivity concerns
• Identical core electrical and thermal operating parameters
• Tape & Reel packaging suitable for automated assembly processes

The height differential of 0.028" (0.71mm) between seated positions requires verification against PCB layout constraints and component clearance specifications in applications with height-restricted designs.

Frequently Asked Questions (FAQ)

Q: Can DOCAT050V-020.0M directly replace DOC050V-020.0M in existing designs?

A: Yes, the DOCAT050V-020.0M provides electrical and functional equivalence across all specified parameters. The seated height difference of 0.028" (0.71mm) must be evaluated against PCB clearance requirements.

Q: What is the significance of the product status change from Obsolete to Active?

A: The Active status of DOCAT050V-020.0M ensures continued manufacturing, availability, and technical support. This eliminates supply chain risk associated with obsolete components.

Q: Are there packaging considerations when switching from DOC050V-020.0M to DOCAT050V-020.0M?

A: The DOCAT050V-020.0M is supplied in Tape & Reel (TR) format, which is standard for automated assembly. Verify that receiving and handling processes accommodate this packaging format.

Q: Do the RoHS and REACH compliance statuses remain unchanged?

A: Yes. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence.

Q: What does the ±15ppm Absolute Pull Range specification on DOCAT050V-020.0M indicate?

A: The APR specification defines the frequency adjustment range available through the control voltage input on the VCOCXO. This parameter was not specified for the original DOC050V-020.0M but is documented for the DOCAT050V-020.0M.

Q: Are the 6-SMD, No Lead packages identical between both parts?

A: The packages are identical in footprint and land pattern. The 0.028" (0.71mm) height difference falls within typical PCB assembly tolerances but should be confirmed for space-constrained applications.
