AX3DBF2-156.2500T Equivalent & Substitute Parts

Part Overview

The AX3DBF2-156.2500T is a 156.25 MHz XO (Standard) LVDS Oscillator manufactured by Abracon LLC from the ClearClock™ AX3 series. This surface mount crystal oscillator operates at 2.5V with Enable/Disable functionality and is designed for applications requiring precise frequency generation with LVDS output. The part is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same frequency, output type, voltage supply, and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX3DBF2-156.2500T are qualified based on strict equivalence of the following parameters:

• Frequency: 156.25 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Voltage Supply: 2.5V (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 / Case: 6-SMD, No Lead (exact match required)
• Size / Dimension: 0.126" L x 0.098" W (3.20mm x 2.50mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)

The identified substitute parts maintain all critical electrical and mechanical parameters. Variations in current supply specifications and seated height do not affect functional substitution when all primary parameters are equivalent.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and are ROHS3 compliant with REACH Unaffected designation. The CL3225-156.250-2.5-25-X-T-TR from Raltron Electronics and SG3225VEN 156.250000M-DDGA3 from EPSON are direct functional equivalents to the AX3DBF2-156.2500T from Abracon LLC.

The CL3225-156.250-2.5-25-X-T-TR operates at a maximum supply current of 40mA with a seated height of 0.047" (1.20mm). The SG3225VEN 156.250000M-DDGA3 operates at a maximum supply current of 25mA with a seated height of 0.047" (1.20mm). The original AX3DBF2-156.2500T operates at 27mA with a seated height of 0.043" (1.10mm). All parts share identical electrical specifications for frequency, output type, voltage supply, function, frequency stability, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: What makes these parts substitutable for the AX3DBF2-156.2500T?

A: The CL3225-156.250-2.5-25-X-T-TR and SG3225VEN 156.250000M-DDGA3 are substitutable because they maintain identical frequency (156.25 MHz), output type (LVDS), supply voltage (2.5V), function (Enable/Disable), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), package type (6-SMD, No Lead), and physical dimensions (0.126" L x 0.098" W / 3.20mm x 2.50mm).

Q: Are there differences in current consumption between these parts?

A: Yes. The AX3DBF2-156.2500T draws a maximum of 27mA, the CL3225-156.250-2.5-25-X-T-TR draws 40mA, and the SG3225VEN 156.250000M-DDGA3 draws 25mA. These differences do not affect functional substitution but should be considered in power budget calculations.

Q: Do the seated height differences affect PCB layout compatibility?

A: The AX3DBF2-156.2500T has a maximum seated height of 0.043" (1.10mm), while both substitute parts have a maximum seated height of 0.047" (1.20mm). This 0.004" (0.10mm) difference is minimal and does not typically affect standard PCB layout designs. Verify clearance requirements for your specific application.

Q: Are all parts available in the same packaging format?

A: The AX3DBF2-156.2500T is available in standard packaging. The CL3225-156.250-2.5-25-X-T-TR is packaged in Tape & Reel (TR) format. The SG3225VEN 156.250000M-DDGA3 is also packaged in Tape & Reel (TR) format. Confirm packaging requirements for your procurement process.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH Unaffected, and classified under ECCN EAR99. All parts have Moisture Sensitivity Level (MSL) of 1 (Unlimited).
