Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC-72.000MBD-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 72 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Package Type: 4-SMD, No Lead
• Package Dimensions: 3.20mm x 2.50mm
• Operating Temperature Range: -40°C ~ 85°C
• Frequency Stability: ±25ppm

The 7X-72.000MBD-T qualifies as a direct substitute based on identical performance across all mandatory parameters. The primary difference lies in the resonator technology (Crystal-based versus MEMS-based) and maximum supply current specification, which does not affect functional compatibility in applications designed for the TC-72.000MBD-T.

Engineering Selection Recommendations

The 7X-72.000MBD-T is a direct functional substitute for the TC-72.000MBD-T based on identical electrical specifications and package compatibility. Selection between these parts should be based on the following factors:

Product Status: The TC-72.000MBD-T is classified as Obsolete, while the 7X-72.000MBD-T maintains Active status. For new designs and long-term supply chain continuity, the 7X-72.000MBD-T is the appropriate selection.

Current Consumption: The 7X-72.000MBD-T operates at a maximum supply current of 15mA compared to 30mA for the TC-72.000MBD-T. This represents a 50% reduction in power consumption, providing a performance advantage in power-sensitive applications.

Physical Height: The 7X-72.000MBD-T has a maximum seated height of 1.10mm versus 0.80mm for the TC-72.000MBD-T. PCB layout clearance must be verified for applications with height constraints.

Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The 7X-72.000MBD-T includes RoHS Compliant and REACH Unaffected certifications.

Frequently Asked Questions (FAQ)

Q: Can the 7X-72.000MBD-T directly replace the TC-72.000MBD-T in existing designs?

A: Yes. Both parts share identical frequency (72 MHz), output type (CMOS), supply voltage (3.3V), Enable/Disable function, frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and package dimensions (3.20mm x 2.50mm). The 7X-72.000MBD-T is electrically and mechanically compatible with applications designed for the TC-72.000MBD-T.

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

A: The TC-72.000MBD-T uses a MEMS (Micro-Electro-Mechanical Systems) resonator, while the 7X-72.000MBD-T uses a Crystal resonator. Both deliver identical frequency stability (±25ppm) and operating characteristics. The resonator technology difference does not affect functional compatibility.

Q: Why is the maximum supply current different between these parts?

A: The TC-72.000MBD-T specifies 30mA maximum supply current, while the 7X-72.000MBD-T specifies 15mA. This difference reflects the distinct resonator technologies and internal circuit designs. The 7X-72.000MBD-T's lower current consumption is advantageous for power-constrained applications.

Q: Are there height clearance concerns when substituting the 7X-72.000MBD-T?

A: The 7X-72.000MBD-T has a maximum seated height of 1.10mm compared to 0.80mm for the TC-72.000MBD-T. PCB layout and component placement must accommodate this 0.30mm height difference. Verify clearance with adjacent components and enclosure constraints.

Q: What is the inventory status of these parts?

A: The TC-72.000MBD-T (Obsolete) has 1118 pieces in stock. The 7X-72.000MBD-T (Active) has 893 pieces in stock. For long-term availability, the Active status of the 7X-72.000MBD-T provides superior supply chain reliability.

Q: Are both parts classified under the same export control and tariff codes?

A: Yes. Both the TC-72.000MBD-T and 7X-72.000MBD-T carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring equivalent regulatory treatment.
