NZ2520SB-32.768KHZ-NSA3535C

Overview

The NZ2520SB-32.768KHZ-NSA3535C is a CMOS standard crystal oscillator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a frequency of 32.768 kHz with a stability of ±30ppm. The device features a supply voltage of 2.5V and draws a maximum current of 260µA during operation, reducing to 10µA in standby mode. It utilizes a 4-SMD, no-lead package measuring 2.50mm x 2.00mm with a maximum height of 0.90mm. The component supports an operating temperature range of -40°C to 85°C and has a Moisture Sensitivity Level (MSL) of 1.

Feature Summary

Integrated CMOS output for direct digital interface compatibility
Low power consumption with dedicated standby mode capability
Compact surface-mount design suitable for space-constrained applications

Applications

Real-time clock circuits in consumer electronics
Timing references for microcontrollers and embedded systems
Portable devices requiring low-power oscillation sources

Procurement Notes

This specific part number is officially obsolete and no longer manufactured by the original equipment manufacturer. Procurement should focus on verified replacement components rather than attempting to source the discontinued item. Verify that any substitute part matches the required pinout, electrical specifications, and package dimensions to ensure seamless integration into existing designs without modification.

Selection Notes

Designers must transition to alternative solutions due to the discontinuation status of this oscillator. When selecting a replacement, prioritize components that maintain the 32.768 kHz frequency and CMOS output type. Ensure the new selection supports the 2.5V supply voltage and fits within the same 2.50mm x 2.00mm footprint to preserve board layout integrity and thermal performance characteristics.

Part Context

This component belongs to the NZ2520S series of surface-mount crystal oscillators from NDK. The series was designed for general-purpose timing applications requiring small form factors. As an obsolete product, it represents a legacy solution previously used in compact electronic devices where space efficiency and moderate power consumption were critical design constraints.
