Key Parameters

Substitute Part Grouping Explanation

Substitution of the DOCAT050F-020.0M is based on strict equivalence of the following critical parameters:

• Frequency: 20 MHz (exact match required)
• Output Logic: LVCMOS (signal compatibility)
• Supply Voltage: 3.3V (power compatibility)
• Frequency Stability: ±50ppb (performance specification)
• Package/Case: 6-SMD, No Lead (physical and electrical footprint compatibility)
• Operating Temperature: 0°C ~ 70°C (thermal operating range)
• Mounting Type: Surface Mount (assembly compatibility)

The DOXSC050F-020.0M meets all these criteria and is classified as a manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The DOXSC050F-020.0M is the direct equivalent substitute for the DOCAT050F-020.0M. Both parts are manufactured by Connor Winfield and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the DOCAT050F-020.0M is discontinued, while the DOXSC050F-020.0M maintains active production status with current inventory availability.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system support. The packaging difference (Cut Tape versus Tape & Reel) reflects standard distribution formats and does not affect component functionality or PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DOXSC050F-020.0M be used as a direct replacement for the DOCAT050F-020.0M?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters: 20 MHz frequency, LVCMOS output, 3.3V supply, ±50ppb stability, and 6-SMD package. PCB footprint and signal compatibility are maintained.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) is supplied in smaller quantities with tape segments cut to length. Tape & Reel (TR) is supplied on continuous reels for high-volume automated assembly. Both formats contain identical components; the difference is distribution and handling format only.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry identical RoHS3 compliance and REACH unaffected status. They meet the same regulatory requirements for industrial and commercial applications.

Q: Does the Absolute Pull Range (APR) difference affect substitution?

A: The DOXSC050F-020.0M specifies ±15ppm APR while the DOCAT050F-020.0M does not list this parameter. APR defines frequency adjustment capability under load conditions. The presence of this specification in the substitute part indicates additional performance data and does not restrict substitution for applications using the main part's specified ±50ppb stability.

Q: What is the inventory status for each part?

A: DOCAT050F-020.0M: 943 pieces available (discontinued status). DOXSC050F-020.0M: 782 pieces available (active production). For new designs and long-term availability, the DOXSC050F-020.0M is the recommended selection.
