NHD-4.6-320240MB-ASXV Equivalent & Substitute Parts

Part Overview

The NHD-4.6-320240MB-ASXV is a 4.6" mountable MVA TFT color graphic LCD display module manufactured by Newhaven Display International. This transmissive RGB display features a 320 x 240 pixel resolution with parallel 24-bit RGB interface and LED white backlight. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NHD-4.6-320240MB-ASXV is determined by the following critical parameters:

• Screen Size: 4.6" (88.90mm) diagonal
• Resolution: 320 x 240 pixels (QVGA)
• Display Technology: TFT color transmissive
• Interface Protocol: Parallel 24-bit RGB
• Backlight: LED white
• Compliance: ROHS3 compliant

Substitute parts must match all primary parameters. Secondary variations in viewing area dimensions, controller type, or interface bit-depth options (16-bit/18-bit/24-bit) are acceptable where the 24-bit RGB mode is supported. Parts with different interface protocols (such as SPI) or display modes are listed as alternatives but require interface adaptation.

Engineering Selection Recommendations

Primary Substitute: NHD-4.6-320240JF-ASXP

The NHD-4.6-320240JF-ASXP is the recommended direct substitute. It maintains identical screen size, resolution, viewing area dimensions, parallel 24-bit RGB interface, and LED white backlight. Both parts are ROHS3 compliant and REACH unaffected. The primary distinction is that the NHD-4.6-320240JF-ASXP is active in production with 6034 units in stock, whereas the original part is obsolete. The IPS display technology of the substitute provides improved viewing angles compared to the MVA technology of the original part.

Secondary Alternatives: E35GF-RW350-N and E35RF-I-RS920-N

The E35GF-RW350-N (Focus LCDs) matches screen size, resolution, and backlight specifications. It supports 24-bit RGB mode within its 16-bit/18-Bit/24-bit RGB interface capability. The viewing area is slightly larger (72.88mm W x 54.96mm H). This part is ROHS3 compliant and active in production.

The E35RF-I-RS920-N (Focus LCDs) matches screen size, resolution, and backlight specifications with a 24-bit RGB interface. However, it uses SPI protocol in addition to RGB, requiring interface adaptation for parallel-only implementations. This part is ROHS3 compliant, REACH unaffected, and active in production.

Frequently Asked Questions (FAQ)

Q: Can the NHD-4.6-320240JF-ASXP directly replace the NHD-4.6-320240MB-ASXV?

A: Yes. Both parts share identical screen size (4.6"), resolution (320 x 240), viewing area dimensions (70.08mm W x 52.56mm H), parallel 24-bit RGB interface, and LED white backlight. The primary difference is display technology (IPS vs. MVA), which affects viewing angle characteristics but maintains functional compatibility.

Q: What is the key difference between the Focus LCDs alternatives and the Newhaven Display parts?

A: The Focus LCDs E35GF-RW350-N and E35RF-I-RS920-N are manufactured by a different supplier. Both maintain the 4.6" screen size, 320 x 240 resolution, and LED white backlight. The E35GF-RW350-N supports 24-bit RGB within a flexible interface. The E35RF-I-RS920-N uses SPI protocol, which differs from the parallel interface of the original part and requires interface adaptation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (NHD-4.6-320240JF-ASXP, E35GF-RW350-N, and E35RF-I-RS920-N) are ROHS3 compliant, matching the compliance status of the original NHD-4.6-320240MB-ASXV.

Q: What packaging options are available for these substitute parts?

A: The NHD-4.6-320240JF-ASXP is supplied in Box packaging. The E35GF-RW350-N is supplied in Tape & Box (TB) packaging. The E35RF-I-RS920-N is supplied in Box packaging.

Q: Can the E35RF-I-RS920-N be used in a parallel RGB interface application?

A: The E35RF-I-RS920-N supports 24-bit RGB and SPI protocols. Applications requiring parallel-only interface would need interface adaptation or controller modification to accommodate the SPI protocol option.
