Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC-19.200MCD-T is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 19.2 MHz (exact match required)
• Output Type: CMOS
• Function: Enable/Disable capability
• Package Type: 4-SMD, No Lead
• Physical Dimensions: 3.20mm x 2.50mm footprint
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Moisture Sensitivity Level: MSL 1

Allowable Variation Parameters:

• Supply Voltage: Substitute may operate at different voltage (3.3V acceptable for 2.5V design with appropriate circuit design consideration)
• Base Resonator Technology: MEMS or Crystal resonator types both acceptable
• Mounted Height: Variation acceptable within PCB assembly constraints
• Product Status: Active status preferred for Obsolete part replacement

The ASE-19.200MHZ-L-R-T meets all mandatory matching parameters and serves as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ASE-19.200MHZ-L-R-T is a functional equivalent for the obsolete TC-19.200MCD-T based on the following engineering criteria:

Compatibility Factors:

• Identical frequency (19.2 MHz) and frequency stability (±25ppm) ensure timing-critical circuit performance equivalence
• Matching CMOS output type and Enable/Disable function provide identical signal interface characteristics
• Identical 4-SMD, No Lead package and 3.20mm x 2.50mm footprint enable direct PCB layout compatibility
• Matching operating temperature range (-40°C ~ 85°C) and MSL 1 rating ensure equivalent environmental performance

Voltage Consideration: The ASE-19.200MHZ-L-R-T operates at 3.3V supply versus the TC-19.200MCD-T at 2.5V. Circuit design must accommodate this voltage difference through appropriate power supply configuration or voltage regulation.

Product Status Advantage: The ASE-19.200MHZ-L-R-T holds Active product status with 1185 units in stock, providing long-term availability and supply chain continuity compared to the Obsolete TC-19.200MCD-T.

Compliance Status: The ASE-19.200MHZ-L-R-T carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the ASE-19.200MHZ-L-R-T directly replace the TC-19.200MCD-T without circuit modification?

A: The ASE-19.200MHZ-L-R-T provides identical frequency, output type, function, and package compatibility. However, the 3.3V supply voltage requirement differs from the TC-19.200MCD-T 2.5V specification. Circuit design must be evaluated to determine if voltage regulation or power supply reconfiguration is necessary.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: frequency (19.2 MHz), output type (CMOS), function (Enable/Disable), package type (4-SMD, No Lead), physical footprint (3.20mm x 2.50mm), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and moisture sensitivity level (MSL 1).

Q: Does the difference in base resonator technology (MEMS vs. Crystal) affect substitution?

A: Both MEMS and Crystal resonator technologies are acceptable for this substitution application. Both the TC-19.200MCD-T (MEMS) and ASE-19.200MHZ-L-R-T (Crystal) meet the identical frequency stability specification of ±25ppm and operating temperature range, making them functionally equivalent.

Q: Is the increased mounted height of the ASE-19.200MHZ-L-R-T (1.20mm vs. 0.80mm) a concern?

A: The ASE-19.200MHZ-L-R-T mounted height of 1.20mm is higher than the TC-19.200MCD-T at 0.80mm. PCB assembly clearance and component placement constraints must be verified to ensure compatibility with the target application.

Q: What is the significance of the ASE-19.200MHZ-L-R-T being in Active product status?

A: Active product status indicates ongoing manufacturing and availability. This provides supply chain continuity and long-term procurement reliability compared to the Obsolete TC-19.200MCD-T, which is no longer manufactured.

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

A: The ASE-19.200MHZ-L-R-T carries ROHS3 compliance and REACH Unaffected status. The TC-19.200MCD-T compliance information is not specified in the provided data. Current procurement standards typically require ROHS3 compliance, which the substitute part satisfies.
