Substitute Part Grouping Explanation

Substitution eligibility for the INT028ATFT-TS is determined by strict alignment with the following core parameters: diagonal screen size (2.8"), display resolution (240 x 320), display type (TFT color), display mode (transmissive), touchscreen type (resistive), and interface capability (parallel). All identified substitute parts maintain these critical specifications, ensuring functional and mechanical compatibility within the original design envelope.

The substitute parts are grouped into two categories based on product status and manufacturing source:

Category 1: Direct Displaytech Equivalent DT028ATFT-TS maintains identical specifications to the main part while offering active product status and improved inventory availability.

Category 2: Focus LCDs Alternatives E28RA-I-CW384-R and E28RG12432LW2M450-R provide equivalent core display functionality with extended interface options (SPI capability in addition to parallel) and active product status. These parts maintain the required 2.8" form factor, 240 x 320 resolution, resistive touchscreen, and parallel interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: DT028ATFT-TS The DT028ATFT-TS is the preferred substitute for INT028ATFT-TS applications. This part is manufactured by the same supplier (Displaytech), maintains identical electrical and mechanical specifications, and carries active product status. The transition from INT028ATFT-TS to DT028ATFT-TS requires no design modifications and provides the highest compatibility assurance. Both parts are RoHS compliant with MSL rating 1.

Secondary Recommendations: E28RA-I-CW384-R and E28RG12432LW2M450-R These Focus LCDs alternatives are suitable for applications where extended interface flexibility is beneficial. Both parts maintain the core 2.8" form factor, 240 x 320 resolution, resistive touchscreen, and parallel interface required for INT028ATFT-TS compatibility. The addition of SPI interface capability provides design flexibility without compromising parallel mode operation. Both parts carry ROHS3 compliance and MSL rating 1. The E28RA-I-CW384-R features a slightly larger viewing area (44.20mm W x 58.60mm H) compared to the original specification (43.20mm W x 57.60mm H), which may require mechanical layout verification. The E28RG12432LW2M450-R maintains the original viewing area dimensions.

Frequently Asked Questions (FAQ)

Q: Can DT028ATFT-TS be used as a direct replacement for INT028ATFT-TS without design changes? A: Yes. DT028ATFT-TS is electrically and mechanically equivalent to INT028ATFT-TS. Both parts share identical display specifications, interface requirements, and physical dimensions. No firmware or hardware modifications are required.

Q: What is the primary difference between the Displaytech and Focus LCDs substitute options? A: DT028ATFT-TS is a direct equivalent from the original manufacturer. E28RA-I-CW384-R and E28RG12432LW2M450-R from Focus LCDs provide the same core display functionality with additional SPI interface capability alongside the required parallel interface. All three substitutes maintain the 2.8" form factor and 240 x 320 resolution.

Q: Are there mechanical compatibility concerns with the Focus LCDs alternatives? A: E28RG12432LW2M450-R maintains the original viewing area dimensions (43.20mm W x 57.60mm H). E28RA-I-CW384-R has a slightly larger viewing area (44.20mm W x 58.60mm H). Mechanical layout verification is recommended for E28RA-I-CW384-R if the display is mounted in a constrained enclosure.

Q: Do all substitute parts meet the same compliance standards as INT028ATFT-TS? A: Yes. DT028ATFT-TS is RoHS compliant. E28RA-I-CW384-R and E28RG12432LW2M450-R are ROHS3 compliant, which represents an enhanced compliance standard. All parts carry MSL rating 1 (Unlimited).

Q: What packaging options are available for these substitute parts? A: DT028ATFT-TS is supplied in Bulk packaging. E28RA-I-CW384-R and E28RG12432LW2M450-R are supplied in Box packaging. Packaging selection should align with procurement and inventory management requirements.

Q: Can the SPI interface on Focus LCDs parts be ignored if only parallel operation is required? A: Yes. The SPI interface is an additional capability. Designs utilizing only the parallel interface will operate identically to INT028ATFT-TS. The parallel interface specifications remain unchanged.
