Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DT070ATFT-TS are qualified based on the following core parameters that determine functional compatibility:

• Diagonal screen size: 7" (177.80mm)
• Display resolution: 800 x 480 pixels
• Display type: TFT - Color transmissive
• Touchscreen: Resistive
• Backlight: LED
• Graphics color: RGB

The DT070CTFT-TS is classified as a direct manufacturer substitute from Displaytech with identical core specifications and active product status. The Focus LCDs parts (E70RC-FW850-R, E70GE1-RW780-R, E70GE2-RW350-R, E70RG38048LW2M430-R) are similar alternatives that maintain the same screen size, resolution, display type, touchscreen technology, and RGB color capability. These parts differ in interface bit-depth options, viewing area dimensions, and controller implementations, but remain functionally equivalent for applications requiring 7" 800 x 480 resistive TFT displays.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete DT070ATFT-TS, the DT070CTFT-TS from Displaytech is the primary substitute option. This part maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance, ensuring long-term availability and regulatory alignment.

The Focus LCDs alternatives (E70RC-FW850-R, E70GE1-RW780-R, E70GE2-RW350-R, E70RG38048LW2M430-R) are qualified substitutes for applications where interface flexibility is beneficial. These parts support multiple bit-depth configurations (16-bit, 18-bit, and 24-bit RGB options) while maintaining the core 7" 800 x 480 resistive TFT display architecture. All Focus LCDs alternatives carry ROHS3 compliance status, meeting current environmental regulations.

Selection between Displaytech and Focus LCDs alternatives should be based on interface requirements, viewing area tolerance, and controller compatibility with existing system designs. The E70GE2-RW350-R and DT070CTFT-TS share identical viewing area dimensions (154.08mm W x 85.92mm H), making them the closest mechanical matches to the original DT070ATFT-TS.

Frequently Asked Questions (FAQ)

Q: Can the DT070CTFT-TS directly replace the DT070ATFT-TS without design modifications?

A: Yes. The DT070CTFT-TS maintains identical specifications for screen size, resolution, display type, touchscreen technology, interface protocol, and viewing area. No design modifications are required for direct substitution.

Q: What are the key differences between Displaytech and Focus LCDs alternatives?

A: The primary differences are interface flexibility and controller implementation. Focus LCDs parts support 16-bit, 18-bit, and 24-bit RGB configurations, while the Displaytech parts specify 24-bit RGB only. Viewing area dimensions vary slightly across Focus LCDs models. All parts maintain the same 7" 800 x 480 resolution and resistive touchscreen capability.

Q: Are the Focus LCDs parts compatible with systems designed for the DT070ATFT-TS?

A: Focus LCDs parts are functionally compatible for applications requiring 7" 800 x 480 resistive TFT displays. However, interface bit-depth configuration and controller-specific timing parameters must be verified against system requirements. The 24-bit RGB interface option on Focus LCDs parts ensures compatibility with designs using the original 24-bit specification.

Q: What is the significance of the viewing area differences between substitute parts?

A: Viewing area dimensions affect the physical display footprint and bezel design. The DT070CTFT-TS and E70GE2-RW350-R match the original 154.08mm W x 85.92mm H specification exactly. Focus LCDs parts E70RC-FW850-R and E70RG38048LW2M430-R have slightly larger viewing areas (approximately 2mm wider and 2mm taller), which may require mechanical enclosure verification.

Q: Which substitute part offers the best compliance profile?

A: All active substitute parts (DT070CTFT-TS and all Focus LCDs alternatives) carry RoHS compliance certifications. The DT070CTFT-TS is RoHS Compliant, while Focus LCDs parts are ROHS3 Compliant. Both certifications meet current regulatory requirements. The DT070CTFT-TS and E70RC-FW850-R specify MSL 1 (Unlimited) moisture sensitivity, matching the original part.

Q: Can multiple interface bit-depths be used interchangeably on Focus LCDs parts?

A: Focus LCDs parts support 16-bit, 18-bit, and 24-bit RGB interface options. System implementation must select and configure the appropriate bit-depth based on controller capabilities and display timing requirements. The 24-bit option ensures compatibility with designs originally specified for 24-bit RGB operation.
