Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm RoHS compliance documentation matches current regulatory requirements. Check datasheet revisions for any parameter updates prior to final design approval. Ensure storage conditions adhere to manufacturer guidelines to maintain solderability and electrical performance.

Selection Notes

Select this component when multi-channel isolation and compact form factor are required. The 1608 package suits space-constrained designs. Verify that the 47 Ohm resistance and 100 pF capacitance values align with target cutoff frequencies. Consider thermal management capabilities within the specified -25°C to +85°C range during system integration.

Part Context

This part belongs to the Panasonic EZA series of chip RC networks. The series focuses on providing integrated passive solutions for noise reduction. The EZA-ST23AAAJ specifically addresses needs for four-channel filtering in a small outline package. It represents a consolidated alternative to discrete component placement.

Replacement Considerations

The product lifecycle status is End of Life. No public substitute part numbers are confirmed in available documentation. Designers should initiate obsolescence management procedures immediately.
