Procurement Notes
Verify the specific ordering suffix to ensure correct packaging options such as tape and reel or cut tape are selected. Confirm that the required load capacitance matches the circuit design specifications. Check RoHS compliance status if environmental regulations apply to the manufacturing process. Ensure the operating temperature range meets the application requirements.
Selection Notes
Select this component when a 26 MHz fundamental frequency is required with tight stability constraints. The 10 pF load capacitance must align with the oscillator circuit's capacitive load. Consider the physical dimensions of the 2.5x2.0 mm package for board space limitations. Verify compatibility with the target microcontroller or oscillator IC input specifications.
Part Context
This part belongs to the NX2520SA series of surface-mount crystals from NDK. It is designed for applications requiring stable frequency generation in compact electronic devices. The series offers various frequency options within the same footprint, allowing for design flexibility across different product lines while maintaining consistent mechanical and electrical characteristics.
Replacement Considerations
Public confirmed substitute part numbers include ABM8N-26.0000MHZ-8-D2Y-T3 from Abracon LLC and ECS-320-10-36-CKL-TR from ECS Inc. These alternatives offer similar surface-mount configurations and frequency specifications. Verify pinout compatibility and load capacitance matching before substitution.
