Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Frequency: 19.2 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±50ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 4-SMD, No Lead
• Package Dimensions: 3.20mm × 2.50mm
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: MSL 1

The 7X-19.200MBE-T qualifies as a direct substitute because it satisfies all mandatory electrical and mechanical parameters. Both parts deliver identical functional performance in applications requiring 19.2 MHz CMOS oscillation with Enable/Disable control at 3.3V supply voltage.

Parameter Comparison

Engineering Selection Recommendations

The 7X-19.200MBE-T is the qualified substitute for the obsolete TC-19.200MBE-T based on the following engineering criteria:

Product Lifecycle Status: The TC-19.200MBE-T carries Obsolete classification, indicating discontinued manufacturing and limited long-term availability. The 7X-19.200MBE-T maintains Active product status, ensuring sustained supply chain access and manufacturing support.

Electrical Equivalence: Both oscillators deliver identical electrical performance across all critical parameters: 19.2 MHz frequency output, CMOS logic levels, 3.3V supply operation, Enable/Disable functionality, and ±50ppm frequency stability across the -40°C to 85°C operating range.

Mechanical Compatibility: Package footprint and mounting characteristics are identical. The 7X-19.200MBE-T exhibits a maximum seated height of 1.10mm compared to 0.80mm for the TC-19.200MBE-T. This 0.30mm height differential must be evaluated within specific PCB layout constraints and clearance requirements.

Compliance Status: The 7X-19.200MBE-T carries RoHS Compliant and REACH Unaffected certifications, supporting regulatory compliance in applications subject to environmental standards.

Supply Current: The 7X-19.200MBE-T operates at a maximum supply current of 20mA, compared to 25mA for the TC-19.200MBE-T. This represents a 5mA reduction in power consumption, providing a performance advantage in power-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the 7X-19.200MBE-T directly replace the TC-19.200MBE-T in existing designs?

A: Yes. Both oscillators share identical electrical specifications (19.2 MHz, CMOS output, 3.3V supply, Enable/Disable function, ±50ppm stability, -40°C to 85°C operation) and package footprint (3.20mm × 2.50mm, 4-SMD No Lead). The 7X-19.200MBE-T is electrically and mechanically compatible for direct substitution.

Q: What is the difference between MEMS and Crystal resonator technology in these parts?

A: The TC-19.200MBE-T uses MEMS (Micro-Electro-Mechanical Systems) resonator technology, while the 7X-19.200MBE-T uses Crystal resonator technology. Both deliver identical frequency stability (±50ppm) and electrical performance in this application. The technology difference does not affect functional compatibility.

Q: Does the height difference between these parts affect PCB assembly?

A: The 7X-19.200MBE-T has a maximum seated height of 1.10mm versus 0.80mm for the TC-19.200MBE-T, representing a 0.30mm increase. This difference must be evaluated against specific PCB clearance requirements, component placement density, and assembly process constraints. In most standard applications, this height differential presents no compatibility issues.

Q: What is the significance of the Tape & Reel packaging for the 7X-19.200MBE-T?

A: Tape & Reel (TR) packaging indicates the substitute part is supplied in continuous tape format suitable for automated pick-and-place assembly equipment. This packaging format is standard for high-volume production environments and does not affect component electrical or mechanical performance.

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

A: The 7X-19.200MBE-T carries RoHS Compliant and REACH Unaffected certifications. The TC-19.200MBE-T compliance status is not specified in available documentation. Both parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What is the current supply difference, and does it matter for my application?

A: The 7X-19.200MBE-T operates at a maximum supply current of 20mA, while the TC-19.200MBE-T requires 25mA. The 5mA reduction in the substitute part represents improved power efficiency and may provide advantages in battery-powered or power-constrained applications. This difference does not affect functional compatibility.

Q: Why is the TC-19.200MBE-T classified as Obsolete?

A: Obsolete classification indicates the manufacturer has discontinued production of this part number. The 7X-19.200MBE-T maintains Active status, ensuring continued availability, manufacturing support, and supply chain reliability for new designs and ongoing production requirements.
