Frequently Asked Questions (FAQ)

Q: Can the 4DLCD-35480320-CTP-IPS be used as a direct replacement for the 4DLCD-35480320-CTP?

A: Yes. The substitute part maintains identical screen size (4.6"), pixel resolution (320 x 480), interface protocols (MCU, SPI), touchscreen technology (capacitive), and mechanical dimensions. All electrical and mechanical parameters required for substitution are matched.

Q: What is the difference between the main part and the substitute?

A: The primary difference is the display technology. The substitute incorporates IPS (In-Plane Switching) technology, which is an enhancement to the standard TFT display. Additionally, the substitute has active product status compared to the obsolete status of the main part.

Q: Are there packaging differences between these parts?

A: Yes. The main part is packaged in a Box, while the substitute is packaged in Bulk. Packaging selection should be based on procurement volume and storage requirements.

Q: Do both parts have the same interface compatibility?

A: Yes. Both parts support MCU and SPI interface protocols, ensuring compatibility with existing system designs.

Q: Are compliance certifications equivalent?

A: Both parts are RoHS compliant. The substitute achieves ROHS3 Compliant status, which represents a more current compliance standard. Both parts share identical MSL, ECCN, and HTSUS classifications.
