Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ULCD-43DCT-AR is determined by the following critical parameters:

• Display diagonal size: 4.3" (109.22mm)
• Resolution: 480 x 272 pixels
• Display type: TFT - Color transmissive
• Touchscreen technology: Capacitive
• Viewing area dimensions: 95.04mm W x 53.86mm H
• Backlight type: LED - White
• Graphics color support: Red, Green, Blue (RGB)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The substitute part GEN4-ULCD-43DCT-CLB-AR meets all core display and mechanical specifications. The primary distinction is interface capability expansion and product status transition from end-of-life to active production.

Parameter Comparison

Engineering Selection Recommendations

The GEN4-ULCD-43DCT-CLB-AR is a direct functional equivalent to the ULCD-43DCT-AR for applications requiring identical display specifications. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component substitution.

The GEN4-ULCD-43DCT-CLB-AR offers expanded interface options (I2C, SPI, TTL) compared to the TTL-only interface of the ULCD-43DCT-AR. Systems designed for TTL interface operation will function without modification. The substitute part's active product status ensures ongoing availability and manufacturing support, whereas the original part is designated "Not For New Designs."

Selection between these parts should be based on procurement availability, inventory requirements, and system interface architecture. Both parts are electrically and mechanically compatible for applications currently using the ULCD-43DCT-AR.

Frequently Asked Questions (FAQ)

Q: Can the GEN4-ULCD-43DCT-CLB-AR replace the ULCD-43DCT-AR in existing systems?

A: Yes. Both parts share identical display specifications, resolution, screen size, viewing area, and backlight characteristics. The substitute part supports TTL interface operation, ensuring compatibility with systems designed for the original part. The expanded interface options (I2C, SPI) are optional and do not affect TTL-based implementations.

Q: What are the key differences between these two parts?

A: The primary differences are product status and interface capability. The ULCD-43DCT-AR is designated "Not For New Designs" and supports TTL interface only. The GEN4-ULCD-43DCT-CLB-AR is an active product offering additional I2C and SPI interface options while maintaining full TTL compatibility.

Q: Are there mechanical or dimensional differences?

A: No. Both parts have identical viewing area dimensions (95.04mm W x 53.86mm H), diagonal screen size (4.3"), and resolution (480 x 272 pixels). Physical mounting and form factor are equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ULCD-43DCT-AR and GEN4-ULCD-43DCT-CLB-AR are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Which part should be selected for new procurement?

A: The GEN4-ULCD-43DCT-CLB-AR is the recommended selection for new procurement due to its active product status and ongoing manufacturing support. The ULCD-43DCT-AR is suitable only for replacement or maintenance of existing systems.
