Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DOC020F-020.0M are qualified based on the following electrical and mechanical parameters:

Core Electrical Parameters (Must Match):

• Frequency: 20 MHz
• Output Logic: LVCMOS
• Supply Voltage: 3.3V
• Frequency Stability: ±20ppb minimum
• Base Resonator Type: Crystal
• Oscillator Type: OCXO

Mechanical Parameters (Must Match):

• Package Type: 6-SMD, No Lead
• Mounting Type: Surface Mount
• Physical Footprint: 0.555" L x 0.358" W (14.10mm x 9.10mm)
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The identified substitutes maintain these critical parameters while differing in product status, packaging format, and extended operating temperature range in the case of the manufacturer-recommended part.

Parameter Comparison

Engineering Selection Recommendations

DOXSC020F-020.0M (Manufacturer Recommended): This part is the preferred substitute. It maintains all core electrical parameters and mechanical compatibility with the DOC020F-020.0M while offering Active product status. The extended operating temperature range (-40°C ~ 85°C) provides broader application flexibility compared to the original part's 0°C ~ 70°C specification. The specified Absolute Pull Range of ±15ppm adds frequency tuning capability. Tape & Reel packaging supports automated assembly processes. ROHS3 compliance and REACH Unaffected status confirm regulatory alignment.

DOCAT020F-020.0M (Direct Substitute): This part provides direct electrical and mechanical compatibility with identical frequency stability and operating temperature range. Product status is Discontinued at DiGi Electronics, indicating limited long-term availability. Tape & Reel packaging is suitable for production environments. ROHS3 compliance and REACH Unaffected status are maintained. This part serves as an intermediate option when DOXSC020F-020.0M is unavailable.

Frequently Asked Questions (FAQ)

Q: Can DOXSC020F-020.0M be used as a direct replacement for DOC020F-020.0M?

A: Yes. Both parts share identical frequency (20 MHz), output type (LVCMOS), supply voltage (3.3V), frequency stability (±20ppb), package type (6-SMD, No Lead), and physical footprint (14.10mm x 9.10mm). The DOXSC020F-020.0M has an extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C) and Active product status, making it suitable for direct substitution in new designs and legacy system support.

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

A: The DOC020F-020.0M has a maximum seated height of 0.307" (7.80mm), while both DOCAT020F-020.0M and DOXSC020F-020.0M have a maximum seated height of 0.335" (8.51mm). This 0.028" (0.71mm) difference must be evaluated for PCB clearance and enclosure constraints in space-limited applications.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, confirming compliance with current environmental and hazardous substance regulations.

Q: What packaging formats are available?

A: The DOC020F-020.0M is supplied in bulk packaging. Both DOCAT020F-020.0M and DOXSC020F-020.0M are supplied in Tape & Reel (TR) format, which is standard for automated assembly and production environments.

Q: Which substitute part should be selected for new designs?

A: DOXSC020F-020.0M is the recommended choice for new designs. It offers Active product status, extended operating temperature range, and specified Absolute Pull Range (±15ppm), providing superior long-term availability and application flexibility.
