Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Frequency: 4.096 MHz
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±50ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 4-SMD, No Lead
• Mounting Type: Surface Mount
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Moisture Sensitivity Level: 1 (Unlimited)

The primary distinction between the main part and its substitute lies in the base resonator technology (MEMS versus Crystal) and maximum supply current specifications. These differences do not affect functional compatibility when all electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The 510CAA4M09600AAGR (Skyworks Solutions Inc.) is a direct functional equivalent to the obsolete TA-4.096MBE-T. Selection of this substitute is supported by the following engineering criteria:

Product Status Alignment: The TA-4.096MBE-T is classified as Obsolete, while the 510CAA4M09600AAGR maintains Active status, ensuring continued availability and manufacturing support.

Electrical Compatibility: Both parts operate identically across all critical electrical parameters: 4.096 MHz frequency output, CMOS logic levels, 3.3V supply voltage, ±50ppm frequency stability, and -40°C to 85°C operating temperature range. Maximum supply current specifications (25mA versus 26mA) fall within acceptable design margins.

Mechanical Compatibility: Both components share identical package specifications (4-SMD, No Lead), footprint dimensions (7.00mm x 5.00mm), and surface mount mounting type. The height difference (1.00mm versus 1.80mm seated height) must be evaluated against specific PCB clearance requirements in the target application.

Regulatory Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, confirming equivalent export and tariff treatment.

Resonator Technology Difference: The TA-4.096MBE-T uses MEMS resonator technology while the 510CAA4M09600AAGR uses crystal resonator technology. This difference does not affect functional performance when all electrical specifications align.

Frequently Asked Questions (FAQ)

Q: Can the 510CAA4M09600AAGR directly replace the TA-4.096MBE-T without PCB modifications?

A: Direct replacement is possible if PCB clearance accommodates the increased seated height (1.80mm versus 1.00mm). Verify vertical clearance above the component location. Electrical connections and footprint are identical.

Q: What is the significance of the MEMS versus Crystal resonator difference?

A: Both resonator technologies deliver identical electrical performance within the specified parameters. The choice between MEMS and crystal does not affect frequency, stability, output type, or operating range for this application.

Q: Are there any supply chain or availability differences between these parts?

A: The TA-4.096MBE-T is Obsolete with limited remaining inventory. The 510CAA4M09600AAGR is Active status with ongoing manufacturing support and standard commercial availability through authorized distributors.

Q: Does the 18mA disable current specification of the 510CAA4M09600AAGR affect system design?

A: The disable current specification applies only when the Enable/Disable function is activated. Verify that system power management requirements align with this parameter. The main part does not specify disable current.

Q: Are the packaging formats interchangeable?

A: The 510CAA4M09600AAGR is supplied in Tape & Reel (TR) format. Verify that your assembly process accommodates this packaging. Both parts use identical component-level packaging (4-SMD, No Lead).

Q: What compliance certifications apply to both parts?

A: Both parts carry EAR99 ECCN classification and 8542.39.0001 HTSUS code, confirming equivalent regulatory treatment for export and tariff purposes.
