Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX3DAF2-125.0000T are qualified based on the following critical parameters that must match or be compatible:

• Frequency: 125 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Type: 6-SMD, No Lead (exact match required)
• Package Dimensions: 3.20mm x 2.50mm (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the AX3DAF2-125.0000T.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active status products with ROHS3 compliance and REACH Unaffected designation, meeting current regulatory requirements. Selection among these equivalents may be based on the following factors derived from provided specifications:

Current Consumption Considerations: The AX3DAF2-125.0000T operates at 27mA maximum supply current. The SG3225VEN 125.000000M-CDGA3 from EPSON operates at 25mA, providing the lowest active current consumption. The CL3225-125.000-3.3-25-X-T-TR from Raltron operates at 40mA, and the NX33C5008Q from Diodes operates at 70mA maximum.

Disable Mode Current: The AX3DAF2-125.0000T specifies 10µA disable current. The NX33C5008Q specifies 40mA disable current. The CL3225 and SG3225VEN do not specify disable mode current in the provided data.

Package Height: The NX33C5008Q offers the lowest seated height at 1.05mm, while the CL3225 and SG3225VEN both measure 1.20mm seated height. The AX3DAF2-125.0000T measures 1.10mm.

Automotive Qualification: The NX33C5008Q carries AEC-Q200 rating, indicating automotive-grade qualification. This part is suitable for applications requiring automotive-level reliability.

All parts are electrically and mechanically interchangeable based on the core parameters of frequency, output type, supply voltage, function, frequency stability, operating temperature range, package type, and dimensions.

Frequently Asked Questions (FAQ)

Q: Can I substitute the AX3DAF2-125.0000T with any of the listed parts?

A: Yes. All listed parts meet the critical electrical and mechanical parameters: 125 MHz frequency, LVDS output, 3.3V supply, Enable/Disable function, ±25ppm frequency stability, -40°C to 85°C operating range, 6-SMD No Lead package, and 3.20mm x 2.50mm dimensions. They are electrically and mechanically interchangeable.

Q: What are the differences between these substitute parts?

A: The primary differences are maximum supply current (25mA to 70mA), disable mode current specifications, seated height (1.05mm to 1.20mm), and automotive qualification. The NX33C5008Q includes AEC-Q200 automotive rating. Current consumption may impact power budget in battery-powered or thermally constrained applications.

Q: Does package height matter for my application?

A: Package height differences range from 1.05mm to 1.20mm. If your PCB design has height constraints or clearance requirements, verify that the substitute part's seated height is compatible with your mechanical layout. The NX33C5008Q at 1.05mm is the most compact option.

Q: Are all these parts RoHS compliant?

A: Yes. All listed parts are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Which part should I choose for automotive applications?

A: The NX33C5008Q from Diodes Incorporated carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. The other parts do not specify automotive ratings in the provided data.

Q: What is the difference in disable mode current between parts?

A: The AX3DAF2-125.0000T specifies 10µA disable current for low-power standby operation. The NX33C5008Q specifies 40µA disable current. The CL3225 and SG3225VEN do not provide disable current specifications. For applications requiring minimal standby power consumption, the AX3DAF2-125.0000T or NX33C5008Q may be preferred.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, provided your PCB footprint accommodates the 6-SMD No Lead package and the seated height of the substitute part does not exceed your mechanical clearance. All parts use identical package dimensions (3.20mm x 2.50mm) and mounting type (Surface Mount).
