Key Parameters

Substitute Part Grouping Explanation

Substitution of the DOC102V-020.0M is determined by the following critical parameters:

• Frequency Match: 20 MHz (exact match required)
• Output Type: LVCMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Package Type: 6-SMD, No Lead (exact match required)
• Package Dimensions: 0.555" L x 0.358" W (14.10mm x 9.10mm) (exact match required)
• Frequency Stability: ±100ppb (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Mounting Type: Surface Mount (exact match required)

The DOCAT102V-020.0M qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is the addition of amplitude control functionality and a marginal increase in seated height (0.335" vs 0.307"), which remains within typical PCB assembly tolerances for surface mount components.

Parameter Comparison

Engineering Selection Recommendations

The DOCAT102V-020.0M is the recommended substitute for the obsolete DOC102V-020.0M. Both components maintain identical electrical specifications for frequency, output type, supply voltage, and frequency stability. The substitute part carries Active product status, ensuring continued availability and manufacturing support.

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, supporting equivalent handling and storage requirements. The marginal increase in seated height (0.028" / 0.71mm) is within standard PCB assembly tolerances and does not present mechanical compatibility concerns for typical surface mount applications.

The addition of amplitude control functionality in the DOCAT102V-020.0M provides enhanced operational flexibility without introducing incompatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the DOCAT102V-020.0M directly replace the DOC102V-020.0M in existing designs?

A: Yes. Both components share identical frequency, output type, supply voltage, frequency stability, and package footprint. The DOCAT102V-020.0M is pin-compatible and electrically equivalent for standard VCOCXO applications.

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

A: The DOCAT102V-020.0M has a maximum seated height of 0.335" compared to 0.307" for the DOC102V-020.0M. This 0.028" difference is within standard PCB assembly clearance specifications and does not affect mechanical compatibility in typical applications.

Q: Why is the DOC102V-020.0M classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured. The DOCAT102V-020.0M, with Active product status, represents the current manufacturing equivalent from Connor Winfield.

Q: Are there compliance differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, moisture sensitivity levels, and regulatory certifications (REACH Unaffected, ECCN EAR99).

Q: What does the amplitude control function in the DOCAT102V-020.0M provide?

A: Amplitude control allows adjustment of output signal amplitude, providing enhanced operational flexibility. This feature does not affect compatibility with designs that do not utilize this capability.

Q: Is the ±10ppm Absolute Pull Range specification on the DOCAT102V-020.0M a compatibility concern?

A: No. The APR specification defines the frequency adjustment range available through the control voltage input. This parameter does not affect compatibility with existing circuit designs and represents an additional capability of the substitute part.
