1. AX3DBF1-125.0000T Substitution Conclusion
The AX3DBF1-125.0000T is a viable direct replacement in terms of core functionality and mechanical specifications. Its primary advantage is significantly reduced power consumption, though note its slightly increased physical height. Compared to the original part (CTS), all key interface parameters are fully matched: frequency (125MHz), output (LVDS), supply voltage (2.5V), enable function, and package dimensions (3.2x2.5mm). This ensures both electrical and physical compatibility. The differences are as follows: First, the operating current drops substantially from 66mA to 27mA, which will notably reduce overall system power dissipation and thermal load, improving energy efficiency and reliability. Second, a maximum disabled-state current of 10µA is explicitly specified—a parameter not provided for the original part—indicating clear and excellent static power characteristics for power management enable/disable functions. Third, the maximum mounted height increases from 1.00mm to 1.10mm. While an interference check is necessary in extremely constrained vertical spaces (e.g., ultra-thin designs), this increase is acceptable for the vast majority of applications. For substitution, no circuit modifications are required beyond verifying the height tolerance, and superior power performance is achieved.
2. AX3DBF1-125.0000T3 Substitution Conclusion
The AX3DBF1-125.0000T3 is identical to the aforementioned 'T' variant in all provided technical parameters, leading to the same conclusion regarding substitution feasibility. However, the 'T3' suffix typically denotes reel packaging or a specific manufacturing process revision. It is essential to confirm its exact definition with the supplier or manufacturer prior to replacement to avoid supply chain misinterpretation. Based on the comparison data, this model shows no differences from the AX3DBF1-125.0000T in any technical specification, including frequency, voltage, output, current, dimensions, and height. The impacts of its key advantages—lower power consumption (27mA vs. 66mA), a well-defined low standby current (10µA), and the slightly greater height (1.10mm vs. 1.00mm)—are identical to those of the 'T' variant. In component part numbers, suffixes (such as T3) are often used to distinguish packaging forms (e.g., reel size, orientation), temperature range codes, or special order numbers. While the two parts are electrically and mechanically interchangeable, direct substitution may not comply with original procurement or assembly specifications if 'T3' represents a specific customer requirement or packaging detail. Therefore, while engineering substitution is viable, the specific meaning of the suffix difference must be verified to ensure complete equivalence in both production and procurement processes.
