Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX3DAF1-156.2500T are qualified based on 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)
• Package Dimensions: 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 substitute parts listed meet these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are Active in product status and maintain full RoHS3 compliance and REACH Unaffected certification, ensuring regulatory compliance across all options. The AX3DAF1-156.2500T and AX3DAF1-156.2500T3 are both Abracon LLC parts within the ClearClock™ AX3 series and are parametrically identical. The NX3231D0156.250000 from Diodes Incorporated (SaRonix-eCera™ NX series) and SG3225VEN 156.250000M-CDGA3 from EPSON (SG3225VEN series) are cross-manufacturer alternatives that meet all electrical and mechanical specifications. Selection among these parts may be based on inventory availability, lead time, or existing supply chain relationships, as all parts satisfy the defined substitution criteria.

Frequently Asked Questions (FAQ)

Q: Can the NX3231D0156.250000 be used as a direct replacement for the AX3DAF1-156.2500T?

A: Yes. Both parts operate at 156.25 MHz with LVDS output, 3.3V supply, Enable/Disable function, ±25ppm frequency stability, -40°C ~ 85°C operating temperature, and identical 6-SMD, No Lead package dimensions (3.20mm x 2.50mm). All regulatory certifications match.

Q: What is the difference between AX3DAF1-156.2500T and AX3DAF1-156.2500T3?

A: These are parametrically equivalent parts from the same manufacturer and series. Both share identical electrical specifications, package type, and dimensions. The difference in part number designation reflects manufacturing or packaging variations, but they are functionally interchangeable.

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

A: Yes. The AX3DAF1-156.2500T and AX3DAF1-156.2500T3 specify 27mA maximum supply current and 10µA disable current. The NX3231D0156.250000 specifies 70mA maximum supply current and 40mA disable current. The SG3225VEN 156.250000M-CDGA3 specifies 25mA maximum supply current. These differences should be evaluated against circuit power budget requirements.

Q: Do all substitute parts have the same package height?

A: No. The AX3DAF1-156.2500T and AX3DAF1-156.2500T3 have a maximum seated height of 0.043" (1.10mm). The NX3231D0156.250000 has 0.041" (1.05mm), and the SG3225VEN 156.250000M-CDGA3 has 0.047" (1.20mm). These variations should be considered for applications with height constraints.

Q: What packaging formats are available for these parts?

A: The AX3DAF1-156.2500T, AX3DAF1-156.2500T3, and NX3231D0156.250000 are supplied in Tape & Reel (TR) format. The SG3225VEN 156.250000M-CDGA3 is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on production volume and handling requirements.
