Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TA-72.000MBD-T is determined by the following critical parameters:

Primary Matching Criteria:

• Frequency: 72 MHz (exact match required)
• Output Type: CMOS
• Function: Enable/Disable capability
• Operating Temperature Range: -40°C ~ 85°C (minimum requirement)
• Moisture Sensitivity Level: MSL 1 or better

Secondary Compatibility Factors:

• Supply Voltage: 3.3V nominal operation (acceptable range: 3.0V to 3.6V)
• Package Type: Surface Mount, 4-SMD or 6-SMD configurations
• Physical Footprint: 7.00mm x 5.00mm base dimensions
• Frequency Stability: ±25ppm or better

The two substitute parts identified meet these criteria with the following distinctions:

510CBA72M0000AAGR (Skyworks Solutions Inc.): Direct substitute with crystal-based resonator, identical electrical specifications, lower maximum supply current (26mA vs. 30mA), and Active product status.

ASVMPC-72.000MHZ-LR-T (Abracon LLC): Functional equivalent with MEMS resonator, wider supply voltage range (2.25V ~ 3.6V), 6-SMD package variant, and Active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred):

The 510CBA72M0000AAGR from Skyworks Solutions Inc. is the primary substitute. This part maintains identical electrical specifications (72 MHz, ±25ppm stability, 3.3V, CMOS output, Enable/Disable function) and operates within the same temperature range. The crystal-based resonator provides equivalent performance to the MEMS design. Maximum supply current is lower (26mA vs. 30mA), reducing power consumption. The part is in Active status, ensuring long-term availability. The 4-SMD, No Lead package matches the original footprint exactly. Height difference (1.80mm vs. 1.00mm) must be verified against PCB clearance constraints.

For Alternative Substitution:

The ASVMPC-72.000MHZ-LR-T from Abracon LLC provides functional equivalence with design flexibility. This MEMS-based oscillator operates across a wider supply voltage range (2.25V ~ 3.6V), accommodating systems with variable power rails. The 6-SMD package with exposed pad offers improved thermal management. Height is reduced to 0.90mm, beneficial for space-constrained applications. The part is in Active status with ROHS3 compliance certification. Package transition from 4-SMD to 6-SMD requires PCB layout modification. Maximum supply current is higher (35mA), requiring power budget reassessment.

Compliance Considerations:

Both substitute parts carry EAR99 ECCN classification and HTSUS code 8542.39.0001, matching the original part's regulatory status. The Abracon part includes explicit ROHS3 compliance and REACH Unaffected status, providing additional environmental certification documentation.

Frequently Asked Questions (FAQ)

Q: Can the 510CBA72M0000AAGR be used as a direct drop-in replacement for the TA-72.000MBD-T?

A: The 510CBA72M0000AAGR is electrically compatible and functionally equivalent. The 4-SMD, No Lead package footprint is identical. However, the maximum height increases from 1.00mm to 1.80mm. PCB clearance above the component must be verified before implementation. No circuit modifications are required.

Q: What is the key difference between the two substitute parts?

A: The 510CBA72M0000AAGR uses a crystal-based resonator, while the ASVMPC-72.000MHZ-LR-T uses MEMS technology (matching the original design). The Skyworks part maintains the 4-SMD package; the Abracon part uses a 6-SMD package with exposed pad. Supply voltage range differs: 3.3V fixed (Skyworks) versus 2.25V ~ 3.6V (Abracon). Maximum supply current is 26mA (Skyworks) and 35mA (Abracon).

Q: Does the ASVMPC-72.000MHZ-LR-T require PCB layout changes?

A: Yes. The transition from 4-SMD to 6-SMD package requires PCB footprint modification. The exposed pad in the 6-SMD variant may require thermal via placement for optimal performance. Physical dimensions remain 7.00mm x 5.00mm, but pad configuration differs. Design validation is necessary before production implementation.

Q: Are both substitute parts available in the same packaging format as the original?

A: The 510CBA72M0000AAGR is supplied in Tape & Reel (TR) format. The ASVMPC-72.000MHZ-LR-T packaging format is not specified in available data. Confirm packaging availability with suppliers before procurement.

Q: What is the impact of the higher supply current in the Abracon part?

A: The ASVMPC-72.000MHZ-LR-T draws a maximum of 35mA compared to 30mA for the original part. In disable mode, it draws 22mA versus unspecified disable current for the TA-72.000MBD-T. Power supply capacity and thermal design must accommodate this 5mA increase in active mode operation.

Q: Can frequency stability be assumed equal across all three parts?

A: The TA-72.000MBD-T and 510CBA72M0000AAGR both specify ±25ppm frequency stability. The ASVMPC-72.000MHZ-LR-T does not provide frequency stability data in available documentation. Frequency stability specifications must be obtained from the manufacturer before selecting this part for applications with tight timing requirements.

Q: Is the Abracon part suitable for applications requiring RoHS compliance?

A: Yes. The ASVMPC-72.000MHZ-LR-T carries explicit ROHS3 Compliant certification and REACH Unaffected status. The original TA-72.000MBD-T and Skyworks 510CBA72M0000AAGR do not include RoHS compliance statements in available data. For regulated applications, the Abracon part provides documented environmental compliance.
