Parameter Comparison

Engineering Selection Recommendations

All three parts—AX3DAF1-156.2500T3, NX3231D0156.250000, and SG3225VEN 156.250000M-CDGA3—are Active products with ROHS3 compliance, REACH Unaffected status, and EAR99 classification. Each part meets the specified electrical and mechanical requirements for 156.25 MHz LVDS oscillator applications at 3.3V with Enable/Disable functionality.

Selection between these parts should consider:

• Current consumption characteristics: The AX3DAF1-156.2500T3 and SG3225VEN 156.250000M-CDGA3 offer lower maximum supply current (27mA and 25mA respectively) compared to the NX3231D0156.250000 (70mA).
• Disable mode current: The AX3DAF1-156.2500T3 specifies 10µA disable current, while the NX3231D0156.250000 specifies 40mA disable current.
• Physical height variation: Seated height ranges from 0.041" (1.05mm) to 0.047" (1.20mm), which may impact PCB layout constraints.
• Packaging format: Tape & Reel (TR) versus Cut Tape (CT) & Digi-Reel® availability.
• Inventory availability: All parts maintain active stock levels.

Frequently Asked Questions (FAQ)

Q: Can NX3231D0156.250000 directly replace AX3DAF1-156.2500T3?

A: The NX3231D0156.250000 meets all critical electrical and mechanical parameters including frequency, output type, supply voltage, function, frequency stability, operating temperature range, package type, and physical dimensions. However, the NX3231D0156.250000 has higher maximum supply current (70mA versus 27mA) and higher disable mode current (40mA versus 10µA), which may impact power budget calculations in applications with strict power consumption requirements.

Q: Can SG3225VEN 156.250000M-CDGA3 directly replace AX3DAF1-156.2500T3?

A: The SG3225VEN 156.250000M-CDGA3 meets all critical electrical and mechanical parameters. The maximum supply current is 25mA, which is comparable to the AX3DAF1-156.2500T3 at 27mA. The disable mode current is not specified for this part. The seated height is 0.047" (1.20mm) compared to 0.043" (1.10mm) for the AX3DAF1-156.2500T3, which may require PCB layout verification.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by exact matching of frequency (156.25 MHz), output type (LVDS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), package type (6-SMD, No Lead), physical dimensions (0.126" L x 0.098" W / 3.20mm x 2.50mm), mounting type (Surface Mount), RoHS status (ROHS3 Compliant), and moisture sensitivity level (1 / Unlimited).

Q: Are there packaging format differences between substitute parts?

A: The 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 format selection depends on assembly process requirements and volume considerations.

Q: Do all substitute parts meet regulatory compliance requirements?

A: All three parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 under export control regulations. All parts share the same HTSUS code (8542.39.0001) and maintain MSL 1 (Unlimited) moisture sensitivity rating.
