• Wearable electronic devices
• Compact IoT sensor nodes

Procurement Notes

This specific part number, NX2016AB-26MHZ ST1, is officially listed as obsolete and no longer manufactured by NDK. Procurement should focus on verifying the availability of new old stock from authorized distributors or sourcing approved replacement components that match the required electrical and mechanical specifications.

Selection Notes

Designers requiring this specification must transition to current production alternatives within the NX2016 series. Selection criteria should prioritize matching the 26 MHz frequency, 7 pF load capacitance, and 2.0x1.6mm package dimensions. Verify that substitute components meet the same thermal stability and drive level requirements for the target application environment.

Part Context

The NX2016AB series represents NDK's ultra-small surface-mount crystal lineup. This model specifically targets high-density PCB layouts where board real estate is limited. The 26 MHz frequency is commonly utilized as a reference clock for wireless communication protocols requiring precise timing synchronization.

Replacement Considerations

Available substitutes include the CS06025-26M. Engineers must verify that alternative parts maintain identical pin configurations, load capacitance values, and frequency tolerances to ensure circuit compatibility without redesign.
