Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX3DBF4-155.5200T3 is determined by strict equivalence across the following critical parameters:

• Frequency: 155.52 MHz (exact match required)
• Output Configuration: LVDS (Low Voltage Differential Signaling)
• Supply Voltage: 2.5V (exact match required)
• Enable/Disable Function: Present
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (minimum coverage required)
• Package Type: 6-SMD, No Lead
• Package Dimensions: 3.20mm x 2.50mm (exact match required)
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

The CL3225-155.520-2.5-25-X-T-TR from Raltron Electronics meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the AX3DBF4-155.5200T3 and CL3225-155.520-2.5-25-X-T-TR are Active production parts with ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

The primary distinction between these parts is the maximum supply current specification: the AX3DBF4-155.5200T3 draws 27mA maximum, while the CL3225-155.520-2.5-25-X-T-TR draws 40mA maximum. The seated height differs by 0.10mm (1.10mm versus 1.20mm). These differences do not affect functional equivalence for applications where the higher current specification and slightly increased height are acceptable within the design constraints.

Selection between these parts should be based on component availability, supply chain considerations, and design margin requirements for power consumption and PCB clearance.

Frequently Asked Questions (FAQ)

Q: Can the CL3225-155.520-2.5-25-X-T-TR be used as a direct replacement for the AX3DBF4-155.5200T3?

A: Yes. Both parts share identical frequency, voltage, output type, function, frequency stability, operating temperature range, and package dimensions. The CL3225-155.520-2.5-25-X-T-TR is a direct functional equivalent.

Q: What is the significance of the different maximum supply current ratings (27mA vs 40mA)?

A: The CL3225-155.520-2.5-25-X-T-TR has a higher maximum supply current specification. This does not prevent substitution but indicates different internal design characteristics. Applications with strict power budgets should account for this difference.

Q: Does the 0.10mm height difference affect PCB layout compatibility?

A: The height difference (1.10mm versus 1.20mm) is minimal. PCB designs accommodating the AX3DBF4-155.5200T3 will accept the CL3225-155.520-2.5-25-X-T-TR without layout modification, provided the design clearance exceeds 1.20mm.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99, meeting current regulatory requirements for component use and export.

Q: What packaging options are available for the substitute part?

A: The CL3225-155.520-2.5-25-X-T-TR is supplied in Cut Tape (CT) and Digi-Reel® packaging formats.
