AX3DAF2-156.2500T Equivalent & Substitute Parts

Part Overview

The AX3DAF2-156.2500T 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 3.3V with Enable/Disable functionality and is housed in a 6-SMD, No Lead package. The part is currently Active in product status with 900 pieces in stock. Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, lead time considerations, or packaging format preferences while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX3DAF2-156.2500T are qualified based on strict parametric equivalence across the following critical criteria:

• 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)
• Size / Dimension: 0.126" L x 0.098" W (3.20mm x 2.50mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these parametric requirements and are therefore electrically and mechanically interchangeable with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

All four part numbers are Active products with ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component deployment.

The AX3DAF2-156.2500T and AX3DAF1-156.2500T3 are both Abracon LLC ClearClock™ AX3 series oscillators with identical electrical specifications and maximum supply current of 27mA. The primary distinction is packaging format: AX3DAF2-156.2500T is supplied in standard packaging, while AX3DAF1-156.2500T3 is supplied in Tape & Reel (TR) format with higher inventory availability (1604 pieces).

The NX3231D0156.250000 from Diodes Incorporated (SaRonix-eCera™ NX series) meets all parametric requirements but operates at a maximum supply current of 70mA, which is higher than the Abracon alternatives. This part is available in Tape & Reel (TR) format with the highest inventory level (3936 pieces) and features a slightly lower seated height of 0.041" (1.05mm).

The SG3225VEN 156.250000M-CDGA3 from EPSON (SG3225VEN series) meets all parametric requirements with a maximum supply current of 25mA and is available in Cut Tape (CT) & Digi-Reel® format with 2799 pieces in stock. This part has a seated height of 0.047" (1.20mm).

Frequently Asked Questions (FAQ)

Q: Can I substitute the AX3DAF2-156.2500T with the AX3DAF1-156.2500T3?

A: Yes. Both parts are from the Abracon LLC ClearClock™ AX3 series with identical electrical specifications, frequency stability, operating temperature range, and package dimensions. The difference is packaging format: AX3DAF1-156.2500T3 is supplied in Tape & Reel (TR) format. Electrical and mechanical compatibility is complete.

Q: What is the difference between the Abracon and Diodes Incorporated oscillators?

A: The NX3231D0156.250000 from Diodes Incorporated meets all parametric requirements for frequency, output type, supply voltage, function, and package dimensions. The key difference is maximum supply current: the Diodes part operates at 70mA compared to 27mA for the Abracon AX3DAF2-156.2500T. Both are Active products with ROHS3 compliance.

Q: Are the seated heights of these oscillators interchangeable?

A: The seated heights vary slightly: AX3DAF2-156.2500T and AX3DAF1-156.2500T3 are 0.043" (1.10mm), NX3231D0156.250000 is 0.041" (1.05mm), and SG3225VEN 156.250000M-CDGA3 is 0.047" (1.20mm). All parts fit within the 6-SMD, No Lead package specification and are mechanically compatible with standard PCB assembly processes. Verify clearance requirements for your specific application.

Q: What packaging formats are available?

A: AX3DAF2-156.2500T is supplied in standard packaging. AX3DAF1-156.2500T3 and NX3231D0156.250000 are supplied in Tape & Reel (TR) format. SG3225VEN 156.250000M-CDGA3 is supplied in Cut Tape (CT) & Digi-Reel® format. Select based on your assembly process requirements.

Q: Do all substitute parts meet regulatory compliance?

A: Yes. All four part numbers are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001. All parts have Moisture Sensitivity Level 1 (Unlimited).
