Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX-12.288MAGV-T are identified based on the following critical parameters that determine functional equivalence:

Matching Parameters (Required for Substitution):

• Frequency: 12.288 MHz
• Frequency Tolerance: ±30ppm
• Load Capacitance: 8pF
• Operating Mode: Fundamental
• Operating Temperature Range: -40°C to 85°C
• Package / Case: 2-SMD, No Lead
• RoHS Compliance: RoHS Compliant
• AEC-Q200 Rating: Yes

Allowable Variation:

• ESR (Equivalent Series Resistance): The AX-12.288MAGV-T specifies 80 Ohms. Substitute parts with 100 Ohms ESR remain functionally compatible within the specified load capacitance and frequency tolerance parameters.

The substitute parts listed below meet all critical matching parameters and maintain electrical compatibility with circuit designs specified for the AX-12.288MAGV-T.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: AA-12.288MAGV-T

The AA-12.288MAGV-T is the recommended substitute for the obsolete AX-12.288MAGV-T. Both parts are manufactured by TXC CORPORATION and share identical electrical specifications for frequency, tolerance, load capacitance, and operating temperature range. The AA-12.288MAGV-T maintains AEC-Q200 compliance and RoHS certification. The primary difference is the reduced package footprint (5.00mm x 3.20mm versus 8.00mm x 4.50mm) and slightly lower ESR (100 Ohms versus 80 Ohms). The AA-12.288MAGV-T is currently in Active product status with confirmed inventory availability.

Secondary Substitute: AA-12.288MDGV-T

The AA-12.288MDGV-T provides an alternative substitute option with identical electrical performance to the AA-12.288MAGV-T. This part shares the same frequency, tolerance, load capacitance, temperature range, and AEC-Q200 compliance. The AA-12.288MDGV-T is also in Active product status with confirmed inventory availability.

Both substitute parts are suitable for direct replacement in applications where the AX-12.288MAGV-T was originally specified, provided that the reduced package dimensions are compatible with the printed circuit board layout.

Frequently Asked Questions (FAQ)

Q: Can the AA-12.288MAGV-T directly replace the AX-12.288MAGV-T in existing designs?

A: Yes. The AA-12.288MAGV-T meets all critical electrical parameters: 12.288 MHz frequency, ±30ppm tolerance, 8pF load capacitance, and -40°C to 85°C operating range. Both parts maintain AEC-Q200 compliance and RoHS certification. The primary consideration is physical package size; the AA-12.288MAGV-T is smaller (5.00mm x 3.20mm versus 8.00mm x 4.50mm), which may require PCB layout verification.

Q: What is the difference between the AA-12.288MAGV-T and AA-12.288MDGV-T?

A: Both parts are electrically identical with matching frequency, tolerance, load capacitance, and operating temperature specifications. The difference lies in the part number designation within the TXC CORPORATION product line. Both are Active status with confirmed inventory.

Q: Does the 100 Ohms ESR in the substitute parts affect circuit performance compared to the 80 Ohms ESR of the main part?

A: The ESR difference of 20 Ohms is within acceptable tolerance for circuits designed to the specified 8pF load capacitance and ±30ppm frequency tolerance. Both ESR values are compatible with standard crystal oscillator circuit designs operating at 12.288 MHz.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. Both AA-12.288MAGV-T and AA-12.288MDGV-T carry AEC-Q200 qualification, which certifies compliance with automotive-grade reliability standards.

Q: What is the impact of the smaller package size on component placement?

A: The substitute parts use a smaller 2-SMD, No Lead package (5.00mm x 3.20mm) compared to the main part (8.00mm x 4.50mm). This reduction in footprint may allow for improved PCB layout density. Verify that the reduced dimensions are compatible with your assembly equipment and PCB design specifications.

Q: Are both substitute parts currently available?

A: Yes. The AA-12.288MAGV-T has 765 pieces in stock, and the AA-12.288MDGV-T has 941 pieces in stock, both listed as New Original inventory.
