Substitute Part Grouping Explanation

Substitution of the TA-24.000MBD-T is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

Frequency: 24 MHz (exact match required)
Output: CMOS
Supply Voltage: 3.3V
Function: Enable/Disable capability
Frequency Stability: ±25ppm
Operating Temperature: -40°C ~ 85°C

Mechanical Compatibility Requirements:

Package: 4-SMD, No Lead
Mounting: Surface Mount
Physical Footprint: 0.276" L x 0.197" W (7.00mm x 5.00mm)
Moisture Sensitivity: MSL 1

All identified substitute parts meet these criteria. The primary distinction between the main part and substitutes is the base resonator technology: the TA-24.000MBD-T uses MEMS technology, while all substitute parts employ crystal-based resonators. Both technologies deliver identical electrical performance within the specified parameters.

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing status, providing long-term availability compared to the obsolete TA-24.000MBD-T. Selection among substitutes should be based on the following factors:

Product Status and Supply Continuity: All substitute parts maintain active product status, ensuring continued availability for production and repair cycles.

Compliance and Certifications: Cardinal Components Inc. parts (CPPC7LT-A7BR-24.0TS, CPPC7LZ-A7BR-24.0TS, CPPFXC7L-A7BR-24.0TS, CPPLC7L-A7BR-24.0TS, CPPLC7LT-A7BR-24.0TS) carry ROHS3 compliance and REACH unaffected status. Suntsu Electronics SXO75C3C481-24.000M carries ROHS3 compliance. Skyworks Solutions 510CBA24M0000AAGR does not list these compliance certifications in the provided data.

Current Consumption: The SXO75C3C481-24.000M operates at 16mA maximum supply current, the lowest among all substitutes. The 510CBA24M0000AAGR operates at 26mA. Cardinal Components parts operate at 25mA, matching the original TA-24.000MBD-T specification.

Physical Height Considerations: The TA-24.000MBD-T has a seated height of 0.039" (1.00mm). The SXO75C3C481-24.000M measures 0.063" (1.60mm), while Skyworks 510CBA24M0000AAGR measures 0.071" (1.80mm), and Cardinal Components parts measure 0.075" (1.90mm). Height differences may impact PCB layout and clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can the TA-24.000MBD-T be directly replaced with any of these substitute parts?

A: Yes. All substitute parts meet the critical electrical and mechanical parameters: 24 MHz frequency, CMOS output, 3.3V supply, enable/disable function, ±25ppm stability, -40°C to 85°C operating range, and 4-SMD no-lead package with 7.00mm x 5.00mm footprint. Direct PCB substitution is supported.

Q: What is the difference between MEMS and crystal-based oscillators in this application?

A: The TA-24.000MBD-T uses MEMS (Micro-Electro-Mechanical Systems) resonator technology, while all substitutes use crystal-based resonators. Both technologies deliver identical electrical performance within the specified parameters for this 24 MHz application. The choice between technologies does not affect circuit functionality or compatibility.

Q: Are there height clearance concerns when substituting?

A: The original TA-24.000MBD-T has a maximum seated height of 0.039" (1.00mm). Substitute parts range from 0.063" to 0.075" in height. If PCB layout includes components or shielding in close proximity above the oscillator, height differences must be evaluated against available clearance.

Q: Which substitute offers the lowest power consumption?

A: The SXO75C3C481-24.000M from Suntsu Electronics operates at 16mA maximum supply current, compared to 25-26mA for other substitutes. This represents a 36-40% reduction in current draw during normal operation.

Q: Do all substitutes support the same packaging options?

A: The substitute parts are available in different packaging formats. Cardinal Components parts are supplied in Tape & Reel (TR) format. Skyworks 510CBA24M0000AAGR is supplied in Tape & Reel (TR) format. Suntsu SXO75C3C481-24.000M is supplied in Bulk format. Packaging selection depends on production volume and handling requirements.

Q: Are there compliance differences between substitute options?

A: Cardinal Components parts (CPPC7LT-A7BR-24.0TS, CPPC7LZ-A7BR-24.0TS, CPPFXC7L-A7BR-24.0TS, CPPLC7L-A7BR-24.0TS, CPPLC7LT-A7BR-24.0TS) and Suntsu SXO75C3C481-24.000M carry ROHS3 compliance certification. Compliance documentation for Skyworks 510CBA24M0000AAGR is not provided in the available data.

Q: What is the frequency stability specification, and is it consistent across all parts?

A: All parts, including the original TA-24.000MBD-T and all substitutes, maintain ±25ppm frequency stability across the -40°C to 85°C operating temperature range. This specification is identical across all options.
