Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX3DAF4-156.2500T3 are qualified based on the following critical parameters that determine functional interchangeability:

• 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)

All identified substitute parts meet these criteria. Variations in supply current, packaging format (Tape & Reel vs. Cut Tape), and seated height do not affect functional substitution when the above parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

All four parts—AX3DAF4-156.2500T3, AX3DAF1-156.2500T3, NX3231D0156.250000, and SG3225VEN 156.250000M-CDGA3—are Active status products with ROHS3 compliance and MSL 1 rating, confirming their suitability for current design requirements.

The AX3DAF4-156.2500T3 and AX3DAF1-156.2500T3 are both Abracon LLC ClearClock™ AX3 series parts with identical electrical specifications and differ only in packaging format. The AX3DAF1-156.2500T3 is supplied in Tape & Reel format, while the AX3DAF4-156.2500T3 packaging format is not specified in the provided data.

The NX3231D0156.250000 (Diodes Incorporated, SaRonix-eCera™ NX series) and SG3225VEN 156.250000M-CDGA3 (EPSON, SG3225VEN series) are cross-manufacturer alternatives. The NX3231D0156.250000 exhibits higher supply current (70mA maximum) and disable current (40mA maximum) compared to the primary part. The SG3225VEN 156.250000M-CDGA3 offers the lowest supply current (25mA maximum) and slightly greater seated height (0.047" vs. 0.043").

Selection among these parts depends on supply chain availability, inventory levels, and specific application power budget constraints. All parts are electrically and mechanically interchangeable within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the AX3DAF1-156.2500T3 directly replace the AX3DAF4-156.2500T3?

A: Yes. Both parts are from the Abracon LLC ClearClock™ AX3 series with identical electrical and mechanical specifications. The difference is packaging format (Tape & Reel vs. unspecified). They are functionally interchangeable.

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

A: The NX3231D0156.250000 (Diodes Incorporated) has higher supply current (70mA vs. 27mA) and higher disable current (40mA vs. 10µA). All other critical parameters—frequency, output type, voltage, function, stability, temperature range, package, and size—are identical. The higher current consumption may impact power budget in applications with strict power constraints.

Q: Is the EPSON SG3225VEN 156.250000M-CDGA3 suitable as a substitute?

A: Yes. The EPSON part meets all critical substitution criteria: 156.25 MHz frequency, LVDS output, 3.3V supply, Enable/Disable function, ±25ppm stability, -40°C to 85°C operating range, 6-SMD No Lead package, and 3.20mm x 2.50mm footprint. It offers the lowest supply current (25mA) and is supplied in Cut Tape & Digi-Reel® format.

Q: Does seated height variation affect substitution?

A: Seated height differences (0.041" to 0.047") are within typical PCB assembly tolerances for 6-SMD, No Lead packages. All parts maintain the same 3.20mm x 2.50mm footprint and mounting type. Height variation does not prevent functional substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four parts carry ROHS3 Compliant status and MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.

Q: What packaging formats are available?

A: AX3DAF4-156.2500T3 packaging is not specified. AX3DAF1-156.2500T3 is supplied in Tape & Reel (TR). NX3231D0156.250000 is supplied in Tape & Reel (TR). SG3225VEN 156.250000M-CDGA3 is supplied in Cut Tape (CT) & Digi-Reel®.
