TA-10.000MBE-T MEMS Oscillator Equivalent & Substitute Parts

Part Overview

The TA-10.000MBE-T is a 10 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 functionally equivalent substitute components essential for ongoing design support and production continuity. Substitute parts must maintain identical electrical performance characteristics and physical compatibility within the specified operating parameters.

Substitute Part Grouping Explanation

Substitute parts for the TA-10.000MBE-T are qualified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

Frequency: 10 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)

Mechanical Equivalence Criteria:

Package / Case: 4-SMD, No Lead (exact match required)
Mounting Type: Surface Mount (exact match required)
Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm) (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All five substitute parts listed meet these criteria. Variations in current consumption, height, base resonator type (MEMS vs. Crystal), and product status do not disqualify substitution when all primary electrical and mechanical parameters align.

Engineering Selection Recommendations

For New Designs and Production Continuity:

The TA-10.000MBE-T is Obsolete. Selection of an Active substitute part is recommended for long-term supply assurance. Three substitute parts carry Active product status:

510CAA10M0000AAGR (Skyworks Solutions Inc.): Active status with established supply chain. Suitable for applications where current consumption up to 26mA is acceptable.
CPPC7L-A7BP-10.0000TS (Cardinal Components Inc.): Active status, ROHS3 Compliant, REACH Unaffected. Includes low disable current (50µA). Suitable for power-sensitive applications.
CPPC7LZ-A7BP-10.0TS (Cardinal Components Inc.): Active status, ROHS3 Compliant, REACH Unaffected. Functionally identical to CPPC7L-A7BP-10.0000TS with equivalent performance.
SXO75C3A481-10.000M (Suntsu Electronics, Inc.): Active status, ROHS3 Compliant. Lowest current consumption (16mA). Optimal for power-constrained applications.

For Legacy System Support:

The 7W-10.000MBE-T (TXC CORPORATION, Obsolete) provides direct manufacturer continuity but remains Obsolete. This part is suitable only for short-term legacy support where existing inventory exists.

All substitute parts maintain identical electrical specifications and physical package compatibility. Selection should be based on product availability, supply chain reliability, compliance certifications, and current consumption requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the TA-10.000MBE-T be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts meet the required electrical and mechanical specifications. They operate at 10 MHz, 3.3V, with CMOS output, Enable/Disable function, ±50ppm frequency stability, and -40°C ~ 85°C operating temperature range. All use identical 4-SMD, No Lead packaging with 7.00mm x 5.00mm dimensions.

Q: What is the difference between MEMS and Crystal base resonators in these oscillators?

A: The TA-10.000MBE-T uses a MEMS resonator, while most substitute parts use Crystal resonators. Both technologies deliver the specified 10 MHz frequency and ±50ppm stability. The choice between MEMS and Crystal does not affect electrical compatibility or substitution validity when all other parameters match.

Q: Are there differences in current consumption between the main part and substitutes?

A: Yes. Current consumption varies: TA-10.000MBE-T (25mA), 7W-10.000MBE-T (20mA), 510CAA10M0000AAGR (26mA), CPPC7L-A7BP-10.0000TS (25mA), CPPC7LZ-A7BP-10.0TS (25mA), and SXO75C3A481-10.000M (16mA). These variations do not prevent substitution. Applications with strict power budgets should select SXO75C3A481-10.000M (16mA) or 7W-10.000MBE-T (20mA).

Q: Do height differences affect PCB layout compatibility?

A: Height variations exist: TA-10.000MBE-T (1.00mm), 7W-10.000MBE-T (1.42mm), 510CAA10M0000AAGR (1.80mm), CPPC7L-A7BP-10.0000TS (1.90mm), CPPC7LZ-A7BP-10.0TS (1.90mm), and SXO75C3A481-10.000M (1.60mm). All heights remain within typical PCB clearance specifications. Verify clearance in your specific design if height-constrained applications exist.

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

A: Active product status indicates ongoing manufacturer support. The 510CAA10M0000AAGR (Skyworks), CPPC7L-A7BP-10.0000TS (Cardinal), CPPC7LZ-A7BP-10.0TS (Cardinal), and SXO75C3A481-10.000M (Suntsu) all carry Active status. Consult distributor inventory and lead times for your specific procurement timeline.

Q: Are there compliance or certification differences between substitute parts?

A: CPPC7L-A7BP-10.0000TS, CPPC7LZ-A7BP-10.0TS, and SXO75C3A481-10.000M carry ROHS3 Compliant and REACH Unaffected certifications. All parts are classified as EAR99 for export control purposes. Verify compliance requirements for your specific application and region.

Q: Can I use the 7W-10.000MBE-T as a substitute despite its Obsolete status?

A: The 7W-10.000MBE-T meets all electrical and mechanical specifications and is functionally equivalent. However, Obsolete status indicates discontinued production. Use only if existing inventory is available and long-term supply is not required. For new designs or ongoing production, select an Active substitute part.
