DOC100V-020.0M VCOCXO Oscillator Equivalent & Substitute Parts

Part Overview

The DOC100V-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 with ±100ppb frequency stability. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional and electrical compatibility for ongoing system support and new production requirements.

Substitute Part Grouping Explanation

The DOCAT100V-020.0M qualifies as a direct substitute for the DOC100V-020.0M based on the following alignment of critical parameters:

• Frequency Match: Both parts operate at 20 MHz
• Oscillator Type: Both are VCOCXO devices
• Output Standard: Both provide LVCMOS output
• Supply Voltage: Both require 3.3V supply
• Frequency Stability: Both maintain ±100ppb stability
• Operating Temperature Range: Both function across 0°C ~ 70°C
• Package Compatibility: Both use 6-SMD, No Lead surface mount packaging with identical footprint dimensions (14.10mm x 9.10mm)
• Compliance: Both are ROHS3 compliant with MSL 1 rating

The DOCAT100V-020.0M represents an active product status alternative, addressing the obsolescence of the original DOC100V-020.0M while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT100V-020.0M is the appropriate substitute for the obsolete DOC100V-020.0M. Both parts maintain identical electrical specifications for frequency, output type, supply voltage, and frequency stability. The DOCAT100V-020.0M offers the additional benefit of an active product status, ensuring continued availability and manufacturing support.

The footprint dimensions remain identical (14.10mm x 9.10mm), enabling direct PCB layout compatibility. The maximum seated height increases by 0.028" (0.71mm) from 7.80mm to 8.51mm; this minor dimensional variance must be evaluated against specific board clearance requirements.

Both parts carry equivalent compliance certifications: ROHS3 compliance, MSL 1 rating, REACH unaffected status, and EAR99 ECCN classification. No additional qualification or testing is required based on regulatory or environmental compliance criteria.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT100V-020.0M directly replace the DOC100V-020.0M in existing designs?

A: Yes. Both parts share identical frequency (20 MHz), output type (LVCMOS), supply voltage (3.3V), frequency stability (±100ppb), operating temperature range (0°C ~ 70°C), and package footprint (14.10mm x 9.10mm). The PCB layout remains compatible without modification.

Q: What is the difference in height between these two parts?

A: The DOC100V-020.0M has a maximum seated height of 7.80mm, while the DOCAT100V-020.0M measures 8.51mm. The 0.71mm difference must be verified against board clearance constraints in your specific application.

Q: Does the DOCAT100V-020.0M include amplitude control functionality?

A: Yes. The DOCAT100V-020.0M includes amplitude control as an additional feature. The DOC100V-020.0M does not specify this function. This enhancement does not affect substitution compatibility.

Q: What is the Absolute Pull Range (APR) specification?

A: The DOCAT100V-020.0M specifies an APR of ±10ppm. The DOC100V-020.0M does not provide this parameter. APR defines the frequency adjustment range achievable through the control voltage input on VCOCXO devices.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the DOC100V-020.0M and DOCAT100V-020.0M are ROHS3 compliant, carry MSL 1 (unlimited) moisture sensitivity rating, are REACH unaffected, and classified under ECCN EAR99.

Q: Why is the DOC100V-020.0M obsolete?

A: The DOC100V-020.0M is classified as obsolete. The DOCAT100V-020.0M represents the active equivalent from Connor Winfield, providing continued product availability and manufacturing support.
