Substitute Part Grouping Explanation

Substitution eligibility for the TC-19.200MBD-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 19.2 MHz
• Output Type: CMOS
• Supply Voltage: 3.3V
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Function: Enable/Disable
• Package Type: 4-SMD, No Lead
• Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm)
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts meet all mandatory parameters. Variations in base resonator technology (MEMS versus Crystal), current consumption, and height-seated dimensions do not preclude substitution when all electrical and functional specifications align.

Parameter Comparison

Engineering Selection Recommendations

7X-19.200MBD-T (TXC CORPORATION): This substitute maintains manufacturer continuity with TXC CORPORATION and is classified as Active product status. It employs a Crystal-based resonator instead of MEMS technology while maintaining identical electrical specifications. The part is RoHS Compliant and REACH Unaffected. Current consumption is reduced to 15mA maximum compared to the main part's 25mA. Height-seated dimension increases to 1.10mm. This option is suitable for applications where manufacturer consistency and active product support are prioritized.

ASE-19.200MHZ-L-R-T (Abracon LLC): This substitute is manufactured by Abracon LLC and carries Active product status. It provides the lowest maximum supply current at 7mA and includes specified disable-mode current consumption of 10µA. The part is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. Height-seated dimension is 1.20mm. This option is suitable for applications where power efficiency and comprehensive compliance documentation are required.

Both substitutes are electrically and functionally equivalent to the TC-19.200MBD-T across all critical parameters. Selection between them depends on design priorities regarding manufacturer preference, power consumption targets, and regulatory compliance documentation requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7X-19.200MBD-T and ASE-19.200MHZ-L-R-T be used interchangeably with the TC-19.200MBD-T?

A: Yes. Both substitute parts meet all mandatory electrical and functional specifications: 19.2 MHz frequency, CMOS output, 3.3V supply, ±25ppm stability, -40°C to 85°C operating range, Enable/Disable function, and 4-SMD No Lead package with identical footprint dimensions. Substitution is valid from an electrical and mechanical compatibility standpoint.

Q: What is the primary difference between the main part and the substitutes?

A: The TC-19.200MBD-T uses MEMS resonator technology, while both substitutes employ Crystal-based resonators. This difference does not affect electrical performance or functional compatibility. The substitutes are Active products, whereas the main part is Obsolete.

Q: Are there height clearance considerations when substituting?

A: Yes. The TC-19.200MBD-T has a maximum seated height of 0.80mm. The 7X-19.200MBD-T measures 1.10mm, and the ASE-19.200MHZ-L-R-T measures 1.20mm. PCB layout and component placement must accommodate these increased heights. Verify clearance in your specific application before implementation.

Q: Which substitute offers the best power efficiency?

A: The ASE-19.200MHZ-L-R-T provides the lowest active supply current at 7mA maximum and includes specified disable-mode current of 10µA. The 7X-19.200MBD-T operates at 15mA maximum. The TC-19.200MBD-T requires 25mA maximum. For power-constrained applications, the Abracon part is the most efficient option.

Q: Are both substitutes RoHS and REACH compliant?

A: The 7X-19.200MBD-T is RoHS Compliant and REACH Unaffected. The ASE-19.200MHZ-L-R-T is ROHS3 Compliant and REACH Unaffected. Both meet current regulatory requirements. The main part's compliance status is not specified in available documentation.

Q: What packaging formats are available for the substitutes?

A: The 7X-19.200MBD-T is supplied in Tape & Reel (TR) format. The ASE-19.200MHZ-L-R-T is also supplied in Tape & Reel (TR) format. Both are suitable for automated assembly processes.

Q: Can I use these substitutes in new designs?

A: Yes. Both substitute parts carry Active product status, ensuring ongoing availability and manufacturer support. They are appropriate for new design implementations. The TC-19.200MBD-T, being Obsolete, is not recommended for new designs.
