DOCAT020F-020.0M Equivalent & Substitute Parts

Part Overview

The DOCAT020F-020.0M is a 20 MHz OCXO (Oven Controlled Crystal Oscillator) with LVCMOS output, designed for applications requiring stable frequency generation at 3.3V supply voltage. This component features a 6-SMD surface mount package with no lead configuration and operates across a 0°C to 70°C temperature range with ±20ppb frequency stability.

The DOCAT020F-020.0M has been discontinued at DiGi Electronics. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for existing applications and new production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DOCAT020F-020.0M is determined by the following critical parameters:

• Frequency: 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)
• Physical Dimensions: 0.555" L x 0.358" W, Height 0.335" max (exact match required)
• Frequency Stability: ±20ppb (minimum requirement)
• RoHS Compliance: ROHS3 Compliant (required)

The DOXSC020F-020.0M qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. While the DOXSC series offers an extended operating temperature range (-40°C ~ 85°C) and additional frequency pull range specification (±15ppm), these represent functional enhancements rather than deviations from the original specification.

Parameter Comparison

Engineering Selection Recommendations

The DOXSC020F-020.0M is the qualified substitute for the discontinued DOCAT020F-020.0M. Both components are manufactured by Connor Winfield and maintain identical electrical specifications for frequency, output type, supply voltage, and frequency stability. Physical dimensions and package configurations are identical, ensuring direct PCB compatibility without layout modifications.

The DOXSC020F-020.0M carries Active product status with current inventory availability, providing supply chain continuity. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, satisfying regulatory and environmental requirements.

The extended operating temperature range of the DOXSC020F-020.0M (-40°C ~ 85°C versus 0°C ~ 70°C) represents a functional enhancement suitable for applications requiring broader thermal operation. The specified ±15ppm absolute pull range on the DOXSC series provides additional frequency adjustment capability not documented on the original DOCAT part.

Frequently Asked Questions (FAQ)

Q: Can the DOXSC020F-020.0M be used as a direct replacement for the DOCAT020F-020.0M without PCB modifications?

A: Yes. Both components share identical package types (6-SMD, No Lead), physical dimensions (0.555" L x 0.358" W, 0.335" height max), and mounting configurations. No PCB layout changes are required.

Q: What are the key differences between these two parts?

A: The primary differences are product status and operating temperature range. The DOCAT020F-020.0M is discontinued, while the DOXSC020F-020.0M is active. The DOXSC series operates from -40°C to 85°C compared to the DOCAT's 0°C to 70°C range. Electrical specifications for frequency, output type, supply voltage, and frequency stability remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the DOCAT020F-020.0M and DOXSC020F-020.0M are ROHS3 compliant with identical moisture sensitivity levels (MSL 1, Unlimited).

Q: What is the frequency stability specification for these oscillators?

A: Both parts maintain ±20ppb frequency stability, meeting the same precision requirements.

Q: Is the DOXSC020F-020.0M suitable for applications originally designed for the DOCAT020F-020.0M?

A: Yes, provided the application's operating temperature requirements fall within the DOXSC's -40°C to 85°C range. The extended temperature capability of the DOXSC makes it suitable for all applications within the original DOCAT's 0°C to 70°C specification.
