1. 514FBB000115CAGR Substitution Conclusion
Based on a comparison of key parameters, the 514FBB000115CAGR can serve as a drop-in replacement for the original part 634L12504I2T, offering superior overall performance. Both are 2.5V active crystal oscillators with a 125 MHz LVDS output and are fully package-compatible (6-SMD, 3.20mm x 2.50mm). The primary differences are: the 514FBB000115CAGR features improved frequency stability of ±25ppm (vs. the original ±30ppm) and a significantly lower maximum operating current of 23mA (vs. 65mA). Its disable current is also slightly lower (18mA vs. 22mA). Substituting with this part will enhance system timing accuracy while substantially reducing power consumption and thermal dissipation, thereby improving system reliability and power efficiency. However, note that the "I2C P" designation likely indicates integrated I2C programmability—a feature not present in the original part. It is essential to verify compatibility of this added functionality within the existing circuit. If I2C configuration is not required, the substitution can typically proceed without issue.
2. 510FBA125M000CAGR Substitution Conclusion
The 510FBA125M000CAGR is also a viable replacement for the original 634L12504I2T, demonstrating excellent electrical and physical compatibility along with a clear power advantage. It matches the original part in frequency, voltage, output type, and package. The key improvements are similarly an enhanced frequency stability of ±25ppm and a drastically reduced maximum operating current of 23mA (vs. 65mA), with a disable current of 18mA. This substitution will yield more precise clock signals and lower system power consumption, benefiting thermal management and power supply design. Note that the "SINGL" descriptor may indicate support for a single-ended output configuration, whereas the original part is fixed LVDS. If only the LVDS output is utilized, functionality is fully matched. However, ensure the hardware layout supports its potential output mode configuration. If no configuration is needed, direct replacement is generally feasible.
