TC-80.000MBD-T Equivalent & Substitute Parts

Part Overview

The TC-80.000MBD-T is an 80 MHz MEMS-based XO (Standard) oscillator manufactured by TXC CORPORATION. This component operates at 3.3V with CMOS output, Enable/Disable function, and is housed in a 4-SMD, No Lead package. The part is classified as Obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for continued system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC-80.000MBD-T is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 80 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• 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)

Both identified substitute parts meet all mandatory parameters. The primary distinction between substitutes lies in the base resonator technology (Crystal vs. MEMS), maximum supply current specifications, and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

7X-80.000MBD-T (TXC CORPORATION): This substitute is an Active product from the same manufacturer (TXC CORPORATION). It provides direct functional equivalence with identical electrical specifications. The 7X series uses Crystal-based resonator technology versus the MEMS technology of the TC series. Maximum supply current is reduced to 15mA compared to 30mA in the main part. The component is RoHS Compliant and REACH Unaffected, supporting modern regulatory requirements. Height dimension increases to 1.10mm from 0.80mm; PCB layout clearance verification is required for space-constrained applications.

ASE-80.000MHZ-L-R-T (Abracon LLC): This substitute is an Active product from Abracon LLC, a qualified alternative manufacturer. Electrical specifications are identical to the main part. The ASE series uses Crystal-based resonator technology. Maximum supply current is 20mA with specified disable current of 10µA. The component is ROHS3 Compliant and REACH Unaffected. Height dimension increases to 1.20mm; PCB layout verification is required. Packaging is supplied as Tape & Reel (TR), suitable for automated assembly processes.

Both substitutes are electrically and mechanically compatible with the TC-80.000MBD-T. Selection between them depends on supply chain availability, preferred manufacturer relationship, and specific PCB height constraints.

Frequently Asked Questions (FAQ)

Q: Can the 7X-80.000MBD-T and ASE-80.000MHZ-L-R-T be used interchangeably with the TC-80.000MBD-T?

A: Both parts meet all mandatory electrical and mechanical compatibility parameters: 80 MHz frequency, CMOS output, 3.3V supply, Enable/Disable function, ±25ppm stability, -40°C to 85°C operating range, 4-SMD No Lead package, and identical footprint dimensions. Direct substitution is supported from an electrical standpoint. Height dimension differences (0.80mm vs. 1.10mm vs. 1.20mm) require verification against PCB clearance requirements.

Q: What is the difference between MEMS and Crystal-based oscillators in these parts?

A: The TC-80.000MBD-T uses MEMS (Micro-Electro-Mechanical Systems) resonator technology, while both substitute parts use Crystal-based resonators. This is a technical distinction in the resonator type; however, both technologies deliver the specified electrical performance parameters for this application.

Q: Are there supply current differences that affect circuit design?

A: Yes. The TC-80.000MBD-T specifies 30mA maximum supply current. The 7X-80.000MBD-T specifies 15mA, and the ASE-80.000MHZ-L-R-T specifies 20mA. Power supply and decoupling capacitor designs based on the original 30mA specification will operate safely with lower-current substitutes. If designs were optimized for lower current, verify that the substitute current specification does not exceed available supply capacity.

Q: What does the disable current specification mean?

A: The ASE-80.000MHZ-L-R-T specifies 10µA maximum current in the Disable state. This parameter is not provided for the main part or the 7X substitute. The disable current represents power consumption when the Enable/Disable function is used to turn off the oscillator output. Lower disable current reduces standby power consumption in battery-powered applications.

Q: Do the height differences affect PCB design?

A: The TC-80.000MBD-T has a maximum seated height of 0.80mm. The 7X-80.000MBD-T is 1.10mm, and the ASE-80.000MHZ-L-R-T is 1.20mm. If the PCB layout includes components or shielding in close proximity above the oscillator, the increased height of substitute parts may create clearance conflicts. Verify PCB cross-section and component placement before substitution.

Q: Are the substitute parts RoHS and REACH compliant?

A: The 7X-80.000MBD-T is RoHS Compliant and REACH Unaffected. The ASE-80.000MHZ-L-R-T is ROHS3 Compliant and REACH Unaffected. Compliance status for the original TC-80.000MBD-T is not specified in the provided data. Both substitutes support modern regulatory requirements for new designs and manufacturing.

Q: What packaging formats are available?

A: The TC-80.000MBD-T and 7X-80.000MBD-T packaging format is not specified. The ASE-80.000MHZ-L-R-T is supplied as Tape & Reel (TR), which is standard for automated assembly processes. Confirm packaging requirements with your procurement and assembly processes.
