Substitute Part Grouping Explanation

Substitute parts for the AX3DAF4-155.5200T3 are qualified based on the following critical parameters:

• Frequency Match: 155.52 MHz (exact)
• Output Configuration: LVDS (exact)
• Supply Voltage: 3.3V (exact)
• Enable/Disable Function: Required
• Frequency Stability: ±25ppm (exact)
• Operating Temperature Range: -40°C ~ 85°C (exact)
• Package Type: 6-SMD, No Lead (exact)
• Physical Footprint: 0.126" L x 0.098" W (3.20mm x 2.50mm) (exact)
• Compliance: ROHS3 Compliant, REACH Unaffected

The CL3225-155.520-3.3-25-X-T-TR from Raltron Electronics meets all critical electrical and mechanical parameters, making it a direct substitute. Both parts share identical frequency, output type, voltage, function, stability, temperature range, and footprint specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the AX3DAF4-155.5200T3 and CL3225-155.520-3.3-25-X-T-TR are Active products with ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. The Abracon part features lower maximum supply current (27mA vs. 40mA) and a lower seated height (1.10mm vs. 1.20mm). The Raltron substitute maintains all critical electrical specifications and footprint compatibility. Selection between these parts should be based on supply availability, lead time, and specific application current budget requirements.

Frequently Asked Questions (FAQ)

Q: Can the CL3225-155.520-3.3-25-X-T-TR replace the AX3DAF4-155.5200T3 in existing designs?

A: Yes. Both parts share identical frequency (155.52 MHz), output type (LVDS), supply voltage (3.3V), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and physical footprint (3.20mm x 2.50mm). The 6-SMD, No Lead package is identical, enabling direct PCB substitution.

Q: What are the differences between these two parts?

A: The primary differences are maximum supply current (Abracon: 27mA, Raltron: 40mA) and seated height (Abracon: 1.10mm, Raltron: 1.20mm). The Raltron part has higher current consumption and slightly greater height. Both differences are within typical design tolerances for LVDS oscillator applications.

Q: Are both parts compliant with current regulations?

A: Yes. Both the AX3DAF4-155.5200T3 and CL3225-155.520-3.3-25-X-T-TR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What is the moisture sensitivity level for these oscillators?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates Unlimited shelf life under normal storage conditions. No special moisture control measures are required during storage or handling.

Q: Can these parts be used interchangeably in high-speed digital applications?

A: Both parts are qualified for LVDS output applications with identical frequency stability (±25ppm) and operating temperature range. Interchangeability is determined by your specific application's current budget and height constraints. Verify that the maximum supply current and seated height of the selected part meet your design requirements.
