T100F-020.0M TCXO Oscillator Equivalent & Substitute Parts

Part Overview

The T100F-020.0M is a 20 MHz temperature-compensated crystal oscillator (TCXO) manufactured by Connor Winfield, designed for applications requiring stable frequency output with enable/disable functionality. This surface-mount device operates at 3.3V supply voltage and delivers LVCMOS-level output signals. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts may be required due to inventory constraints, design revisions, or application-specific performance requirements that differ from the original specification.

Key Parameters

Substitute Part Grouping Explanation

The T602-020.0M qualifies as a direct substitute based on the following critical parameters:

Matching Parameters:

• Frequency: 20 MHz (identical)
• Output Type: LVCMOS (identical)
• Supply Voltage: 3.3V (identical)
• Function: Enable/Disable (identical)
• Package Type: 10-SMD, No Lead (identical)
• Physical Dimensions: 7.00mm x 5.00mm x 2.40mm (identical)
• RoHS3 Compliance (identical)
• Moisture Sensitivity Level: 1 (identical)

Differing Parameters:

• Frequency Stability: ±280ppb (vs. ±100ppb for T100F-020.0M)
• Operating Temperature Range: -40°C ~ 85°C (vs. 0°C ~ 70°C for T100F-020.0M)
• Maximum Supply Current: 6mA (vs. 2.1mA for T100F-020.0M)

Substitution is valid when the application tolerates the wider frequency stability specification, extended temperature operating range, and higher current consumption of the T602-020.0M.

Parameter Comparison

Engineering Selection Recommendations

Both the T100F-020.0M and T602-020.0M are active production parts with full RoHS3 compliance and REACH unaffected status. Selection between these parts depends on application requirements:

Select T100F-020.0M when:

• Frequency stability of ±100ppb is required
• Operating temperature range of 0°C ~ 70°C is sufficient
• Lower power consumption (2.1mA maximum) is critical

Select T602-020.0M when:

• Extended operating temperature range (-40°C ~ 85°C) is required
• Frequency stability of ±280ppb is acceptable
• Higher current consumption (6mA maximum) is tolerable

Both parts maintain identical physical footprints, electrical interfaces, and compliance certifications, enabling direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can T602-020.0M replace T100F-020.0M in all applications?

A: Direct substitution is valid only when the application tolerates the T602-020.0M's wider frequency stability specification (±280ppb vs. ±100ppb), extended temperature range (-40°C ~ 85°C vs. 0°C ~ 70°C), and higher current draw (6mA vs. 2.1mA). Applications with strict frequency stability or power budget constraints require the original T100F-020.0M.

Q: Are the physical packages identical?

A: Yes. Both parts use 10-SMD, No Lead packaging with identical dimensions of 7.00mm x 5.00mm x 2.40mm maximum height. No PCB layout modifications are required for mechanical compatibility.

Q: Do both parts support the same electrical interface?

A: Yes. Both parts operate at 3.3V supply voltage, provide LVCMOS-level output, and include enable/disable functionality. Signal-level compatibility is maintained between the two parts.

Q: What is the significance of the frequency stability difference?

A: The T100F-020.0M specifies ±100ppb frequency stability, while the T602-020.0M specifies ±280ppb. This difference affects long-term frequency accuracy. Applications requiring tighter frequency tolerance must use the T100F-020.0M.

Q: Are both parts RoHS compliant?

A: Yes. Both the T100F-020.0M and T602-020.0M are ROHS3 compliant with moisture sensitivity level 1 (unlimited). Both are REACH unaffected.
