TA-20.000MBE-T Equivalent & Substitute Parts

Part Overview

The TA-20.000MBE-T is a 20 MHz MEMS-based XO (Standard) CMOS oscillator manufactured by TXC CORPORATION. This component operates at 3.3V with Enable/Disable functionality in a 4-SMD, No Lead surface mount package. The part is classified as Obsolete, making identification of equivalent and substitute components essential for design continuity and procurement planning. Substitute parts must maintain identical electrical performance characteristics and mechanical compatibility to ensure direct replacement capability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TA-20.000MBE-T are qualified based on the following critical parameters:

Electrical Compatibility Requirements:

• Frequency: 20 MHz (exact match required)
• Output: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Maximum Supply Current: Must not exceed 25mA

Mechanical Compatibility Requirements:

• Package Type: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 7.00mm x 5.00mm (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Moisture Sensitivity Level: MSL 1 (exact match required)

The two substitute parts listed below meet all electrical and mechanical compatibility criteria. Differences in base resonator technology (MEMS versus Crystal), supply current specifications, seated height, and product status are noted but do not preclude substitution when the above critical parameters align.

Parameter Comparison

Engineering Selection Recommendations

CPPC7L-A7BP-20.0TS (Cardinal Components Inc.)

This substitute part is classified as Active product status, ensuring ongoing availability and manufacturer support. It carries ROHS3 compliance certification and is supplied in Tape & Reel packaging format. The seated height of 1.90mm exceeds the original part specification of 1.00mm; this difference must be evaluated against PCB layout constraints and clearance requirements in the target application. Supply current specification matches the original part at 25mA maximum. The crystal-based resonator technology differs from the MEMS technology of the original part but maintains identical electrical performance parameters.

SXO75C3A481-20.000M (Suntsu Electronics, Inc.)

This substitute part is classified as Active product status with ROHS3 compliance certification and bulk packaging availability. The maximum supply current specification of 16mA is lower than the original part's 25mA rating, providing improved power efficiency. The seated height of 1.60mm exceeds the original specification of 1.00mm and must be verified against PCB layout constraints. Crystal-based resonator technology maintains electrical performance equivalence to the original MEMS-based design.

Both substitute parts satisfy all critical electrical and mechanical compatibility requirements. Selection between them should be based on packaging format preference, seated height accommodation in the target PCB design, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can CPPC7L-A7BP-20.0TS and SXO75C3A481-20.000M be used interchangeably with TA-20.000MBE-T?

A: Both substitute parts meet all critical electrical specifications (frequency, output type, supply voltage, function, frequency stability, and operating temperature range) and mechanical requirements (package type, physical dimensions, and mounting type). They are electrically and mechanically compatible for direct replacement. However, the increased seated height of both substitutes (1.90mm and 1.60mm respectively, compared to 1.00mm for the original) must be verified against PCB layout and component clearance requirements.

Q: What is the difference between MEMS and Crystal resonator technology in these oscillators?

A: The original TA-20.000MBE-T uses MEMS (Micro-Electro-Mechanical Systems) resonator technology, while both substitute parts use crystal resonator technology. Both technologies deliver identical electrical performance at the specified parameters (20 MHz frequency, ±50ppm stability, 3.3V operation, CMOS output). The choice between technologies is transparent to circuit operation when electrical specifications are matched.

Q: Are there any compliance or certification differences between these parts?

A: The substitute parts CPPC7L-A7BP-20.0TS and SXO75C3A481-20.000M both carry ROHS3 compliance certification. The original TA-20.000MBE-T does not specify RoHS status in the provided data. Both substitute parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications as the original part.

Q: What is the significance of the seated height difference?

A: The original part specifies a maximum seated height of 1.00mm. CPPC7L-A7BP-20.0TS has a maximum seated height of 1.90mm, and SXO75C3A481-20.000M has 1.60mm. These differences must be evaluated against PCB layout, component placement density, and clearance to adjacent components or enclosure constraints. If the original design has minimal vertical clearance, the taller substitute parts may require PCB redesign or component repositioning.

Q: Which substitute part offers better power efficiency?

A: SXO75C3A481-20.000M specifies a maximum supply current of 16mA, compared to 25mA for both the original part and CPPC7L-A7BP-20.0TS. This represents improved power efficiency. However, both specifications are within acceptable operating ranges for most applications. Power consumption differences should be evaluated against the specific application's power budget requirements.

Q: What packaging formats are available for these substitute parts?

A: CPPC7L-A7BP-20.0TS is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. SXO75C3A481-20.000M is supplied in Bulk format. Packaging format selection depends on manufacturing process requirements and volume considerations.

Q: Are there any supply current disable specifications for these parts?

A: CPPC7L-A7BP-20.0TS specifies a maximum disable current of 50µA. SXO75C3A481-20.000M does not provide disable current specification in the available data. The original TA-20.000MBE-T also does not specify disable current. Disable current performance should be verified with manufacturer datasheets if low-power standby operation is critical to the application.
