T100F-019.2M TCXO Oscillator Equivalent & Substitute Parts

Part Overview

The T100F-019.2M is a 19.2 MHz Temperature Compensated Crystal Oscillator (TCXO) manufactured by Connor Winfield. This surface mount oscillator delivers LVCMOS output at 3.3V supply with enable/disable functionality, designed for applications requiring stable frequency reference in the 0°C to 70°C operating range. The part is Active status and ROHS3 compliant. Substitute parts may be required due to inventory constraints, extended temperature range requirements, or specific application thermal profiles.

Key Parameters

Substitute Part Grouping Explanation

The T602-019.2M qualifies as a direct substitute based on the following critical parameters:

• Identical frequency: 19.2 MHz
• Identical output type: LVCMOS
• Identical supply voltage: 3.3V
• Identical function: Enable/Disable
• Identical package: 10-SMD, No Lead
• Identical physical footprint: 7.00mm x 5.00mm
• Identical RoHS and moisture sensitivity compliance

Substitution is valid where the extended operating temperature range (-40°C to 85°C) and higher frequency stability tolerance (±280ppb vs ±100ppb) are acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

Both parts are Active status products with ROHS3 compliance and identical regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001).

Select T100F-019.2M when:

• Operating temperature range is limited to 0°C to 70°C
• Frequency stability of ±100ppb is required
• Lower supply current (2.1mA max) is critical for power-constrained applications
• Height clearance of 2.40mm is acceptable

Select T602-019.2M when:

• Extended temperature operation (-40°C to 85°C) is required
• Frequency stability tolerance of ±280ppb is acceptable
• Higher supply current (6mA max) is tolerable
• Reduced height (2.00mm) provides PCB layout advantages
• Inventory availability is a priority (1526 pcs vs 754 pcs)

Frequently Asked Questions (FAQ)

Q: Can T602-019.2M replace T100F-019.2M in all applications?

A: Substitution is valid only when the application tolerates the extended temperature range, higher frequency stability tolerance (±280ppb), and increased supply current (6mA). If the design requires ±100ppb stability or operates exclusively within 0°C to 70°C, the original T100F-019.2M is specified.

Q: Are the physical footprints identical?

A: Yes. Both parts use 10-SMD, No Lead package with 7.00mm x 5.00mm footprint. The T602-019.2M has a lower seated height (2.00mm vs 2.40mm), which may provide PCB layout benefits in space-constrained designs.

Q: What is the impact of frequency stability difference?

A: The T100F-019.2M provides ±100ppb stability while T602-019.2M provides ±280ppb. Applications requiring tighter frequency tolerance must use the T100F-019.2M. The 180ppb difference is significant for precision timing applications.

Q: Are both parts RoHS compliant?

A: Yes. Both T100F-019.2M and T602-019.2M are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the supply current difference impact?

A: T100F-019.2M draws 2.1mA maximum while T602-019.2M draws 6mA maximum. In battery-powered or power-limited applications, the T100F-019.2M is preferred. The T602-019.2M requires higher power budget consideration.
