Procurement Notes

Verify the obsolete status of this specific part number before initiating procurement processes. Confirm that alternative components meet the required electrical specifications and physical footprint constraints. Ensure compatibility with existing manufacturing equipment and soldering profiles. Review current supply chain availability for potential lead time impacts.

Selection Notes

Select this component when a precise 40 MHz reference is required with minimal external passive components. The integrated 8 pF capacitance reduces board space and simplifies layout. Consider the ±0.2% stability requirement against environmental operating conditions ranging from -40°C to +85°C. Evaluate the 40 Ohm impedance match for the target oscillator circuit.

Part Context

This part belongs to the TDK CCR series of thin-type ceramic chip resonators. These devices typically employ thickness shear mode or third over-tone thickness expansion mode elements. The series covers frequencies from 4.0 MHz upwards, offering a balance between performance and size for consumer and industrial electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineering teams must identify cross-reference components that match the 40 MHz frequency, 8 pF load capacitance, and SMD package dimensions.
