Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX3DBF1-156.2500T3 are qualified based on the following critical parameters that must match or be compatible:

• Frequency: 156.25 MHz (exact match required)
• Output: LVDS (exact match required)
• Supply Voltage: 2.5V (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)
• Packaging Format: Tape & Reel (TR) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The identified substitute parts meet all critical electrical and mechanical parameters. Variations in maximum supply current and seated height are within acceptable tolerances for this product category and do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three components—AX3DBF1-156.2500T3 (Abracon LLC), CL3225-156.250-2.5-25-X-T-TR (Raltron Electronics), and SG3225VEN 156.250000M-DDGA3 (EPSON)—are Active status products with ROHS3 compliance and REACH Unaffected certification. Each component meets the specified electrical and mechanical requirements for 156.25 MHz LVDS oscillator applications at 2.5V supply voltage.

Selection between these parts may be based on inventory availability, lead time, supply chain preferences, or cost considerations. The CL3225-156.250-2.5-25-X-T-TR supports higher maximum supply current (40mA) compared to the primary part (27mA) and the EPSON alternative (25mA). The SG3225VEN 156.250000M-DDGA3 offers the lowest maximum supply current at 25mA, which may be advantageous for power-constrained applications. All parts are suitable for direct substitution in designs requiring 156.25 MHz LVDS oscillators with Enable/Disable functionality.

Frequently Asked Questions (FAQ)

Q: Can CL3225-156.250-2.5-25-X-T-TR be used as a direct replacement for AX3DBF1-156.2500T3?

A: Yes. Both components share identical frequency (156.25 MHz), output type (LVDS), supply voltage (2.5V), 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), and compliance certifications (ROHS3, REACH Unaffected). The CL3225 variant supports higher maximum supply current (40mA vs. 27mA) and slightly greater seated height (0.047" vs. 0.043"), which do not affect functional compatibility.

Q: What are the differences between the EPSON SG3225VEN 156.250000M-DDGA3 and the Abracon AX3DBF1-156.2500T3?

A: The EPSON part operates at lower maximum supply current (25mA vs. 27mA) and has greater seated height (0.047" vs. 0.043"). All other electrical and mechanical parameters are identical, including frequency, output type, supply voltage, function, frequency stability, operating temperature, package type, and physical dimensions.

Q: Are there any restrictions on substituting these oscillators in existing designs?

A: No restrictions exist based on the provided parameters. All three parts meet identical specifications for frequency, output, voltage, function, stability, temperature range, package type, and compliance requirements. Physical dimensions and mounting characteristics are compatible across all three components.

Q: What is the significance of the 6-SMD, No Lead package for these oscillators?

A: The 6-SMD, No Lead package is a surface mount configuration with six solder pads and no through-hole leads. This package type is standard for modern oscillator designs and ensures compatibility with automated assembly processes and PCB layouts designed for surface mount technology.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All three components—AX3DBF1-156.2500T3, CL3225-156.250-2.5-25-X-T-TR, and SG3225VEN 156.250000M-DDGA3—have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
