Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7V-24.576MDHV-T is determined by the following critical parameters:

Primary Substitution Criteria:

• Frequency: 24.576 MHz (exact match required)
• Frequency Tolerance: ±20ppm (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Parameters:

• Load Capacitance: 8pF (preferred for direct substitution)
• ESR: 60 Ohms (preferred for direct substitution)

The substitute parts identified maintain the core electrical specifications (frequency, tolerance, operating mode, temperature range) and physical package format. Variations in load capacitance and ESR are noted where they occur, as these parameters may require circuit design verification depending on the application's oscillator circuit design.

Parameter Comparison

Engineering Selection Recommendations

CX3225GB24576D0HPQCC (KYOCERA AVX) is the parametric equivalent substitute for the 7V-24.576MDHV-T. This part maintains identical electrical specifications (frequency, tolerance, load capacitance, ESR) and physical dimensions. Both parts are RoHS compliant with MSL 1 rating. The CX3225GB series is ROHS3 compliant and REACH affected, providing enhanced regulatory compliance documentation. This substitute requires no circuit design modifications and is suitable for direct replacement in production assemblies.

IXA12-HF5F10-24.576MHZ (ILSI) is a functional substitute with design considerations. While maintaining the required frequency, tolerance, and operating temperature range, this part differs in load capacitance (10pF vs. 8pF) and ESR (120 Ohms vs. 60 Ohms). The IXA12 series also features a smaller physical footprint (2.00mm x 1.60mm vs. 3.20mm x 2.50mm) and lower profile height (0.55mm vs. 0.90mm). This part carries AEC-Q200 automotive qualification and ROHS3 compliance. Circuit design verification is required to confirm compatibility with the application's oscillator circuit, particularly regarding load capacitance and ESR specifications.

Frequently Asked Questions (FAQ)

Q: Can the CX3225GB24576D0HPQCC be used as a direct replacement for the 7V-24.576MDHV-T?

A: Yes. The CX3225GB24576D0HPQCC maintains identical electrical parameters (24.576 MHz, ±20ppm tolerance, 8pF load capacitance, 60 Ohms ESR) and physical dimensions (3.20mm x 2.50mm, 0.90mm height). No circuit modifications are required.

Q: What are the key differences between the IXA12-HF5F10-24.576MHZ and the 7V-24.576MDHV-T?

A: The IXA12 differs in three parameters: load capacitance (10pF vs. 8pF), ESR (120 Ohms vs. 60 Ohms), and physical dimensions (2.00mm x 1.60mm vs. 3.20mm x 2.50mm, with 0.55mm vs. 0.90mm height). The frequency, tolerance, and operating temperature range are identical. Circuit design verification is necessary to confirm compatibility.

Q: Are all three parts RoHS compliant?

A: Yes. The 7V-24.576MDHV-T is RoHS compliant. Both substitute parts (CX3225GB24576D0HPQCC and IXA12-HF5F10-24.576MHZ) are ROHS3 compliant, which represents enhanced regulatory compliance.

Q: What is the significance of the load capacitance difference in the IXA12 substitute?

A: Load capacitance affects the oscillator circuit's frequency stability and startup characteristics. The IXA12's 10pF load capacitance differs from the 7V's 8pF specification. The application's oscillator circuit must be designed or verified to operate correctly with the substitute's load capacitance value.

Q: Can the smaller IXA12 package be used in the same PCB footprint as the 7V?

A: The IXA12 (2.00mm x 1.60mm) is physically smaller than the 7V (3.20mm x 2.50mm). While the package type is identical (4-SMD, No Lead), the smaller dimensions may not align with existing PCB footprints designed for the larger 7V package. PCB layout verification is required.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous tape reels suitable for automated assembly equipment. Cut Tape (CT) packaging is supplied as individual tape segments. The choice depends on assembly process requirements and volume needs.
