AX3DAF2-156.2500T3 Equivalent & Substitute Parts

Part Overview

The AX3DAF2-156.2500T3 is a 156.25 MHz XO (Standard) LVDS Oscillator manufactured by Abracon LLC from the ClearClock™ AX3 series. This crystal oscillator operates at 3.3V with Enable/Disable functionality and is housed in a 6-SMD, No Lead package. The part is Active in product status and widely used in telecommunications and high-speed data transmission applications requiring precise frequency generation with LVDS output compatibility.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or specific packaging preferences while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX3DAF2-156.2500T3 is determined by strict alignment of the following critical parameters:

• Frequency: 156.25 MHz (exact match required)
• Output: 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: -40°C ~ 85°C (exact match required)
• Package/Case: 6-SMD, No Lead (exact match required)
• Physical Dimensions: 3.20mm x 2.50mm (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria. Variations in current supply specifications, packaging format (Tape & Reel vs. Cut Tape), and seated height do not affect functional substitutability within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and full compliance with ROHS3 and REACH requirements. Selection between the main part and substitutes should be based on:

AX3DAF1-156.2500T3: Parametric equivalent from Abracon LLC with identical electrical specifications and physical dimensions. Differs only in packaging format (Tape & Reel). Suitable for high-volume production environments requiring reel packaging.

NX3231D0156.250000: Direct manufacturer equivalent from Diodes Incorporated (SaRonix-eCera™ NX series). Maintains all critical electrical parameters. Maximum supply current is 70mA compared to 27mA in the main part; seated height is 1.05mm. Appropriate for applications where higher current capability is beneficial or where Diodes Incorporated supply chain preference exists.

SG3225VEN 156.250000M-CDGA3: Direct manufacturer equivalent from EPSON (SG3225VEN series). Maintains all critical electrical parameters. Maximum supply current is 25mA; seated height is 1.20mm. Packaging format is Cut Tape & Digi-Reel®. Suitable for applications prioritizing EPSON component sourcing or where lower current draw is advantageous.

Frequently Asked Questions (FAQ)

Q: Can AX3DAF1-156.2500T3 be used as a direct replacement for AX3DAF2-156.2500T3?

A: Yes. Both parts are from the Abracon LLC ClearClock™ AX3 series with identical electrical specifications, frequency stability, operating temperature range, and physical dimensions. The only difference is packaging format (Tape & Reel vs. standard packaging). PCB layout and schematic integration remain unchanged.

Q: What are the key differences between the Abracon and Diodes Incorporated oscillators?

A: The NX3231D0156.250000 from Diodes Incorporated has a maximum supply current of 70mA versus 27mA for the Abracon AX3DAF2. All other critical parameters—frequency, output type, voltage, stability, and package dimensions—are identical. The higher current specification does not affect compatibility; it indicates the maximum current the part may draw under specified conditions.

Q: Is the EPSON SG3225VEN 156.250000M-CDGA3 compatible with the original design?

A: Yes. The EPSON part meets all critical electrical and mechanical specifications. The seated height is 1.20mm compared to 1.10mm in the main part. Verify PCB clearance in the vertical direction before substitution. All other parameters align with design requirements.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Cut Tape packaging formats do not affect electrical characteristics or performance. Selection is based on manufacturing process requirements and inventory management practices.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed—AX3DAF2-156.2500T3, AX3DAF1-156.2500T3, NX3231D0156.250000, and SG3225VEN 156.250000M-CDGA3—are ROHS3 Compliant and REACH Unaffected.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. All substitute parts carry MSL 1 rating, eliminating moisture-related handling constraints during storage and assembly.
