AX3DBF3-155.5200T3 Equivalent & Substitute Parts

Part Overview

The AX3DBF3-155.5200T3 is a 155.52 MHz XO (Standard) LVDS Oscillator manufactured by Abracon LLC as part of the ClearClock™ AX3 series. This surface mount oscillator operates at 2.5V with Enable/Disable functionality and is housed in a 6-SMD, No Lead package. The part is currently Active in product status with 804 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to availability constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

The CL3225-155.520-2.5-25-X-T-TR from Raltron Electronics qualifies as a direct substitute based on the following critical parameters:

• Identical frequency: 155.52 MHz
• Identical output type: LVDS
• Identical supply voltage: 2.5V
• Identical function: Enable/Disable
• Identical frequency stability: ±25ppm
• Identical operating temperature range: -40°C ~ 85°C
• Identical package type: 6-SMD, No Lead
• Identical physical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm)
• Identical compliance certifications: ROHS3 Compliant, REACH Unaffected, EAR99

These parameters define the substitution criteria for this oscillator category. Variations in maximum supply current and seated height do not preclude substitution when the primary electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

Both the AX3DBF3-155.5200T3 and CL3225-155.520-2.5-25-X-T-TR are Active products with full ROHS3 compliance and REACH Unaffected status. The Abracon part offers lower maximum supply current (27mA vs 40mA) and a lower seated height (1.10mm vs 1.20mm). The Raltron part provides higher current capacity and is available in Cut Tape and Digi-Reel packaging options. Selection between these parts should be based on supply availability, packaging requirements, and specific application current budgets. Both parts meet identical electrical and mechanical specifications for the core oscillator function.

Frequently Asked Questions (FAQ)

Q: Can the CL3225-155.520-2.5-25-X-T-TR replace the AX3DBF3-155.5200T3 in my design?

A: Yes. Both parts share identical frequency (155.52 MHz), output type (LVDS), supply voltage (2.5V), function (Enable/Disable), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and package type (6-SMD, No Lead). Physical dimensions are identical at 0.126" L x 0.098" W.

Q: What are the differences between these two parts?

A: The primary differences are maximum supply current (27mA for Abracon vs 40mA for Raltron), seated height (1.10mm vs 1.20mm), and packaging options (Raltron offers Cut Tape and Digi-Reel). Both parts are ROHS3 compliant and REACH Unaffected.

Q: Does the higher maximum supply current of the Raltron part affect compatibility?

A: No. Higher maximum supply current indicates greater current capacity and does not create incompatibility. The part will operate within the same voltage and frequency specifications as the Abracon part.

Q: Are there any PCB layout considerations when switching between these parts?

A: The identical physical dimensions (0.126" L x 0.098" W) and package type (6-SMD, No Lead) ensure direct PCB footprint compatibility. The seated height difference of 0.004" (0.10mm) is negligible for standard surface mount assembly processes.

Q: What packaging options are available for each part?

A: The Abracon AX3DBF3-155.5200T3 is available in standard packaging. The Raltron CL3225-155.520-2.5-25-X-T-TR is available in Cut Tape (CT) and Digi-Reel packaging options, providing flexibility for different procurement and assembly workflows.
