Key Parameters

Substitute Part Grouping Explanation

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

• Display Specifications: Diagonal screen size of 4.3" (109.22mm), resolution of 480 x 272 pixels, TFT color transmissive technology, and RGB graphics capability
• Physical Dimensions: Viewing area of 95.04mm W x 53.86mm H
• Interface Compatibility: Support for I2C and TTL communication protocols
• Backlight Type: LED white backlight
• Compliance: ROHS3 compliance and REACH unaffected status

The GEN4-ULCD-43D meets all core display and interface requirements while maintaining the same screen size, resolution, and color capability. The substitute part supports an expanded interface set (I2C, SPI, TTL) and represents an active product line, providing long-term availability and support.

Parameter Comparison

Engineering Selection Recommendations

The GEN4-ULCD-43D is the direct substitute for the ULCD-43P. Both components maintain identical display specifications, physical dimensions, and core interface protocols. The substitute part is manufactured by the same supplier and carries equivalent ROHS3 compliance and REACH unaffected status.

The GEN4-ULCD-43D offers extended interface support through the addition of SPI protocol capability, providing design flexibility without compromising compatibility with existing I2C and TTL implementations. The active product status of the GEN4-ULCD-43D ensures continued availability and technical support, addressing the obsolescence of the original ULCD-43P.

Frequently Asked Questions (FAQ)

Q: Can the GEN4-ULCD-43D directly replace the ULCD-43P in existing designs?

A: Yes. Both parts share identical display resolution (480 x 272), screen size (4.3"), viewing area dimensions, color capability (RGB), and backlight type (LED white). The substitute part supports all interface protocols of the original part (I2C and TTL) plus additional SPI capability.

Q: What is the difference in dot pitch between these parts?

A: The ULCD-43P has a dot pitch of 0.15mm W x 0.15mm H, while the GEN4-ULCD-43D has a dot pitch of 0.20mm W x 0.20mm H. Both maintain the same 480 x 272 pixel resolution across the identical 95.04mm x 53.86mm viewing area.

Q: Are there packaging differences between the ULCD-43P and GEN4-ULCD-43D?

A: The GEN4-ULCD-43D is supplied in box packaging. Packaging specifications for the ULCD-43P were not provided in the technical data.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ULCD-43P and GEN4-ULCD-43D are ROHS3 compliant and REACH unaffected.

Q: Why is the GEN4-ULCD-43D recommended over the obsolete ULCD-43P?

A: The GEN4-ULCD-43D is an active product with ongoing manufacturer support and availability. The ULCD-43P is obsolete and no longer in production. The substitute part provides equivalent functionality with extended interface options.
