• Display resolution: 480 x 272 pixels
• Display type: TFT - Color
• Display mode: Transmissive
• Touchscreen type: Capacitive
• Graphics color: Red, Green, Blue (RGB)
• Backlight: LED - White
• Viewing area: 95.04mm W x 53.86mm H
• RoHS compliance: ROHS3 Compliant
• Regulatory classification: HTSUS 8524.91.1000

Functional Enhancement: The SK-GEN4-43DCT-CLB extends interface capability by supporting I2C and SPI protocols in addition to TTL, providing greater design flexibility while maintaining full TTL compatibility with existing SK-43DCT implementations.

Parameter Comparison

Engineering Selection Recommendations

For Existing Designs: The SK-43DCT remains suitable for maintenance and repair of fielded systems where component replacement is required. Inventory availability is confirmed at 713 units.

For New Designs: The SK-GEN4-43DCT-CLB is the appropriate selection. This part maintains full electrical and mechanical compatibility with SK-43DCT specifications while offering active product status and extended interface support. The SK-GEN4-43DCT-CLB carries superior inventory availability at 967 units and is classified as Active by the manufacturer, ensuring long-term supply chain stability.

Both parts maintain equivalent RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can SK-GEN4-43DCT-CLB directly replace SK-43DCT in existing applications?

A: Yes. Both parts share identical display specifications (4.3" 480 x 272 TFT capacitive touchscreen), viewing area dimensions, and TTL interface support. The SK-GEN4-43DCT-CLB adds I2C and SPI interface options but maintains full backward compatibility with TTL-based designs.

Q: What is the significance of the "Not For New Designs" status on SK-43DCT?

A: This designation indicates the manufacturer has transitioned this product to end-of-life status and recommends the SK-GEN4-43DCT-CLB for new development. Existing inventory remains available for replacement purposes.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in Box packaging. Verify specific kit contents (accessories, cables, storage modules) with the supplier, as the SK-43DCT kit includes ULCD-43DCT display, USD-4GB storage, and UUSB-PA5 programming cable.

Q: How do the dot pitch specifications differ?

A: SK-43DCT specifies 0.07mm W x 0.20mm H dot pitch, while SK-GEN4-43DCT-CLB specifies 0.20mm W x 0.20mm H. Both achieve the same 480 x 272 resolution across the 95.04mm x 53.86mm viewing area through different pixel geometry.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both SK-43DCT and SK-GEN4-43DCT-CLB are ROHS3 Compliant and REACH Unaffected, meeting equivalent environmental and regulatory standards.
