Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4DLCD-35480320-RTP is determined by strict alignment of the following critical parameters:

• Display Diagonal Size: 4.6" (88.90mm) — exact match required
• Pixel Resolution: 320 x 480 — exact match required
• Display Type: TFT - Color transmissive technology
• Touchscreen Type: Resistive touchscreen interface
• Interface Protocol: MCU and SPI support
• Graphics Color: Red, Green, Blue (RGB)
• Dot Pitch: 0.20mm W x 0.20mm H
• Viewing Area: 48.96mm W x 73.44mm H
• Backlight Technology: LED

The substitute part 4DLCD-35480320-RTP-IPS meets all critical dimensional, electrical, and functional parameters. The primary distinction is the addition of IPS (In-Plane Switching) technology to the display panel, which enhances viewing angle characteristics while maintaining full compatibility with the original interface specifications and mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

The 4DLCD-35480320-RTP-IPS is a direct functional substitute for the obsolete 4DLCD-35480320-RTP. Both parts maintain identical electrical interface specifications, mechanical dimensions, and pixel resolution. The substitute part carries active product status with current manufacturing support, whereas the original part is obsolete.

Compliance considerations favor the substitute: the 4DLCD-35480320-RTP-IPS meets ROHS3 compliance standards, representing a more current regulatory alignment compared to the original RoHS Compliant designation. Both parts maintain MSL 1 (Unlimited) moisture sensitivity ratings and share identical ECCN and HTSUS classifications.

The IPS display technology enhancement in the substitute part provides improved viewing angle performance without introducing any interface or mechanical incompatibility. Backlight specification expansion in the substitute (LED - Red/Green/Blue/White versus LED) indicates enhanced backlight options while maintaining baseline LED functionality.

Frequently Asked Questions (FAQ)
