TA-4.096MBD-T MEMS Oscillator Equivalent & Substitute Parts

Part Overview

The TA-4.096MBD-T is a 4.096 MHz MEMS-based XO (Standard) oscillator manufactured by TXC CORPORATION. This component operates at 3.3V with CMOS output, Enable/Disable function capability, and is housed in a 4-SMD, No Lead surface mount package. The part is currently classified as obsolete, making identification of compatible substitute components essential for ongoing production and maintenance applications. Equivalent parts must maintain identical electrical performance characteristics and physical compatibility to ensure seamless integration into existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TA-4.096MBD-T is determined by strict alignment of the following critical parameters:

Electrical Compatibility Requirements:

• Frequency: 4.096 MHz (exact match required)
• Output: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match or wider range acceptable)
• Maximum Supply Current: 25mA (equal or lower acceptable)

Mechanical Compatibility Requirements:

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

The CPPC7LZ-A7BR-4.096TS from Cardinal Components Inc. meets all mandatory electrical and mechanical compatibility criteria. The primary difference is the base resonator technology (Crystal vs. MEMS) and product status (Active vs. Obsolete), which do not affect functional equivalence when all specified parameters align.

Parameter Comparison

Engineering Selection Recommendations

The CPPC7LZ-A7BR-4.096TS qualifies as a direct functional equivalent to the TA-4.096MBD-T based on matching electrical specifications and package dimensions. Selection considerations are as follows:

Product Status Advantage: The substitute part is classified as Active, providing assured long-term availability and supply chain continuity compared to the obsolete main part.

Compliance Certifications: The CPPC7LZ-A7BR-4.096TS carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic components in regulated markets.

Physical Compatibility: Both parts share identical footprint dimensions (7.00mm x 5.00mm) and MSL 1 rating. The substitute exhibits a maximum seated height of 1.90mm versus 1.00mm for the main part. This height difference must be evaluated against PCB layout constraints and clearance requirements in the target application.

Electrical Performance: All critical electrical parameters align exactly: 4.096 MHz frequency, 3.3V supply, CMOS output, Enable/Disable function, ±25ppm stability, and 25mA maximum current draw.

Packaging Format: The main part is supplied in bulk packaging, while the substitute is available in Tape & Reel format. Procurement and assembly processes must accommodate this difference.

Frequently Asked Questions (FAQ)

Q: Can the CPPC7LZ-A7BR-4.096TS be used as a direct replacement for the TA-4.096MBD-T in existing designs?

A: Yes, the CPPC7LZ-A7BR-4.096TS meets all electrical and mechanical compatibility requirements. The 0.90mm height difference (1.90mm vs. 1.00mm) must be verified against PCB clearance specifications before implementation.

Q: What is the significance of the different base resonator technologies (MEMS vs. Crystal)?

A: Both MEMS and Crystal-based oscillators deliver identical electrical performance when specifications align. The resonator technology does not affect functional equivalence in this application, as both achieve the specified ±25ppm frequency stability and operating characteristics.

Q: Are there any compliance or regulatory differences between the two parts?

A: The substitute part (CPPC7LZ-A7BR-4.096TS) provides explicit ROHS3 compliance and REACH Unaffected certification. The main part specifications do not include these certifications. Applications requiring regulatory compliance should prioritize the substitute part.

Q: Does the Tape & Reel packaging of the substitute affect compatibility?

A: Tape & Reel packaging is a supply format difference only and does not affect component functionality or PCB compatibility. Assembly equipment must be configured to handle the packaging format during production.

Q: What should be verified before finalizing the substitution?

A: Verify that the 1.90mm maximum seated height of the substitute part does not violate PCB layout clearance requirements, particularly in high-density designs or applications with height constraints.

Q: Are the electrical performance characteristics guaranteed to be identical?

A: Yes. Both parts specify identical frequency (4.096 MHz), frequency stability (±25ppm), supply voltage (3.3V), output type (CMOS), function (Enable/Disable), operating temperature range (-40°C ~ 85°C), and maximum supply current (25mA).
