7CZ-32.768KBD-T

Oscillators Overview

The TXC Corporation 7CZ-32.768KBD-T is a standard clock oscillator utilizing quartz or ceramic technology, designed for surface-mount applications in a 4-SMD, no-lead package measuring 5.00mm x 3.20mm with a maximum height of 1.40mm. It operates at a nominal frequency of 32.768 kHz with CMOS output logic and a supply voltage of 3.3V. The device maintains a frequency stability of ±25ppm across an industrial operating temperature range of -40°C to +85°C. Maximum supply current is specified at 3mA. This component is currently obsolete and no longer manufactured.

Oscillators Feature Summary

• CMOS output interface compatible with standard digital logic circuits
• Industrial-grade thermal performance spanning -40°C to +85°C
• Compact surface-mount footprint suitable for space-constrained designs

Oscillators Applications

• Real-time clock (RTC) modules requiring precise timekeeping
• Microcontroller system base clocks
• Industrial control equipment timing references

Oscillators Procurement Notes

This component is officially discontinued and no longer manufactured by TXC Corporation. Procurement must rely on remaining distributor stock or authorized secondary market channels. Verify part authenticity carefully due to potential surplus availability. Confirm that the specific package dimensions and electrical parameters match the target design requirements before acquisition, as direct replacement may require circuit adjustments.

Oscillators Selection Notes

Engineers should transition to active alternatives within the 7CZ series, such as the 7CZ-32.768KBA-T, which shares identical mechanical and electrical specifications. Ensure the substitute part supports the required 3.3V supply and CMOS output levels. Review the manufacturer's Product Change Notification (PCN) documents to verify any updates to materials or manufacturing processes that might affect long-term reliability or compliance status.

Oscillators Part Context

The 7CZ-32.768KBD-T belongs to the 7CZ series of standard oscillators from TXC Corporation. This series provides reliable timing solutions for embedded systems. The 'BD' suffix typically denotes specific packaging or tolerance variations within the family. As an obsolete part, it represents previous generation inventory now superseded by updated production runs like the KBA variant.

Oscillators Replacement Considerations

The manufacturer recommends the 7CZ-32.768KBA-T as the official substitute. Both parts share identical frequency, voltage, package size, and stability specifications. No hardware redesign is required when migrating from the BD model to the BA model.
