Engineering Selection Recommendations

7X-150.000MBD-T (Direct Substitute - Preferred)

The 7X-150.000MBD-T is the primary substitute for the obsolete TC-150.000MBD-T. Both parts are manufactured by TXC CORPORATION and share identical electrical specifications: 150 MHz frequency, ±25ppm stability, 3.3V supply, CMOS output, Enable/Disable function, and -40°C ~ 85°C operating range. The 7X series uses Crystal resonator technology versus MEMS in the TC series. The 7X-150.000MBD-T maintains the same 4-SMD, No Lead package and 3.20mm x 2.50mm footprint. Maximum supply current is 15mA, which is lower than the TC part's 30mA specification. The 7X-150.000MBD-T is Active status with RoHS Compliance certification, ensuring long-term availability and regulatory compliance.

ASEMPC-150.000MHZ-LR-T (Similar Substitute - Alternative)

The ASEMPC-150.000MHZ-LR-T manufactured by Abracon LLC provides an alternative substitute with identical frequency, stability, output type, function, and operating temperature range. This part uses MEMS resonator technology matching the TC series. Supply voltage range is 2.25V ~ 3.6V, providing broader compatibility than the fixed 3.3V specification. The package is 6-SMD, No Lead with the same 3.20mm x 2.50mm footprint dimensions. Maximum supply current is 35mA, exceeding the TC part requirement. Height is 0.90mm, intermediate between the TC (0.80mm) and 7X (1.10mm) parts. The ASEMPC-150.000MHZ-LR-T is Active status with ROHS3 Compliance and REACH Unaffected certification.

Frequently Asked Questions (FAQ)

Q: Can the 7X-150.000MBD-T directly replace the TC-150.000MBD-T without design modifications?

A: Yes. Both parts share identical electrical specifications (150 MHz, ±25ppm, 3.3V, CMOS, Enable/Disable, -40°C ~ 85°C) and the same 4-SMD, No Lead package with 3.20mm x 2.50mm footprint. The primary difference is resonator technology (Crystal versus MEMS) and lower maximum supply current (15mA versus 30mA). If the design draws less than 15mA during operation, direct substitution is valid. The 7X part's 1.10mm height versus the TC part's 0.80mm height requires verification of available PCB assembly clearance.

Q: What is the key difference between the 7X-150.000MBD-T and ASEMPC-150.000MHZ-LR-T?

A: The 7X-150.000MBD-T uses Crystal resonator technology and maintains fixed 3.3V supply voltage with 4-SMD packaging. The ASEMPC-150.000MHZ-LR-T uses MEMS resonator technology with broader 2.25V ~ 3.6V supply voltage range and 6-SMD packaging. Both deliver identical frequency and stability. The ASEMPC part provides higher maximum supply current (35mA) and lower height (0.90mm), offering better performance margins in some applications.

Q: Are there package compatibility concerns when substituting these parts?

A: The 7X-150.000MBD-T uses 4-SMD, No Lead packaging identical to the TC part. The ASEMPC-150.000MHZ-LR-T uses 6-SMD, No Lead packaging. Both maintain the same 3.20mm x 2.50mm footprint dimensions. However, the 6-SMD configuration has additional pins compared to 4-SMD. PCB layout and schematic must be verified to confirm pin compatibility. Height differences (TC: 0.80mm, 7X: 1.10mm, ASEMPC: 0.90mm) require clearance validation for assembly equipment and enclosure fit.

Q: Which substitute part offers the best long-term availability?

A: Both the 7X-150.000MBD-T and ASEMPC-150.000MHZ-LR-T are Active status parts with current inventory. The 7X-150.000MBD-T is manufactured by TXC CORPORATION, the original manufacturer of the TC series, providing continuity of supply chain relationships. The ASEMPC-150.000MHZ-LR-T is manufactured by Abracon LLC, an established oscillator supplier. Both parts carry RoHS compliance certifications (RoHS Compliant and ROHS3 Compliant respectively), supporting regulatory requirements for new designs.

Q: What supply current specifications should I verify before substitution?

A: The TC-150.000MBD-T specifies 30mA maximum supply current. The 7X-150.000MBD-T specifies 15mA maximum. The ASEMPC-150.000MHZ-LR-T specifies 35mA maximum. Measure or calculate the actual supply current draw in your application during normal operation and Enable/Disable transitions. If your design requires more than 15mA, the 7X part is unsuitable. If your design operates within 15mA, the 7X part is acceptable. The ASEMPC part provides the highest current margin.

Q: Are there voltage supply considerations for the ASEMPC substitute?

A: The ASEMPC-150.000MHZ-LR-T operates across 2.25V ~ 3.6V supply voltage range, compared to the fixed 3.3V specification of the TC and 7X parts. If your design uses a regulated 3.3V supply, the ASEMPC part operates within specification. If your design uses variable or lower voltage supplies (2.25V ~ 3.3V range), the ASEMPC part provides broader compatibility. Verify that your power supply regulation and filtering meet the oscillator's noise and stability requirements across the operating voltage range.
