INT028ATFT Equivalent & Substitute Parts

Part Overview

The INT028ATFT is a 2.8-inch TFT color LCD display module manufactured by Displaytech, featuring a 240 x 320 pixel resolution with parallel interface and RGB color support. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and production continuity. The module uses LED backlighting and operates in transmissive mode, suitable for embedded graphics applications requiring compact display solutions.

Substitute Part Grouping Explanation

Substitute parts for the INT028ATFT are selected based on strict equivalence across the following critical parameters:

Primary Matching Criteria:

Diagonal screen size: 2.8" (71.12mm)
Pixel resolution: 240 x 320
Display technology: TFT color transmissive
Interface type: Parallel
Color format: RGB
Backlight type: LED

Substitute Categories:

Category 1: Direct Displaytech Equivalent The DT028ATFT maintains identical specifications to the INT028ATFT across all core parameters. This part represents the active production equivalent from the same manufacturer, differing only in product status (active vs. obsolete) and packaging format (bulk vs. standard).

Category 2: Focus LCDs Alternatives The E28RA-FW480-N and E28RA-I-CW480-N are Focus LCDs modules that match the INT028ATFT on screen size, resolution, display type, and interface capabilities. Both parts support parallel interface with 18-bit RGB and SPI options, providing functional equivalence for parallel-based designs. Minor viewing area variations (44.80mm W x 59.55mm H or 44.80mm W x 60.25mm H versus 43.20mm W x 57.60mm H) fall within acceptable mechanical tolerances for display module substitution.

Engineering Selection Recommendations

For Direct Replacement (Preferred): The DT028ATFT is the recommended substitute for the INT028ATFT. Both parts are manufactured by Displaytech and maintain identical electrical and mechanical specifications. The DT028ATFT carries active product status with ROHS3 compliance certification and significantly higher inventory availability (2400 units), ensuring supply chain continuity.

For Alternative Sourcing: The E28RA-FW480-N and E28RA-I-CW480-N from Focus LCDs provide functional equivalence for applications requiring parallel interface operation. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The inclusion of SPI interface capability on these modules provides additional design flexibility beyond the original INT028ATFT specification. Viewing area differences are within acceptable mechanical tolerances for standard display module applications.

Compliance Considerations: All substitute parts meet or exceed the RoHS compliance level of the original INT028ATFT. The Focus LCDs modules provide REACH compliance documentation, which may be required for certain end-market applications.

Frequently Asked Questions (FAQ)

Q: Can the DT028ATFT directly replace the INT028ATFT without design modifications? A: Yes. The DT028ATFT maintains identical specifications across all electrical and mechanical parameters. No design modifications are required for direct substitution.

Q: What are the key differences between the Displaytech DT028ATFT and Focus LCDs alternatives? A: The primary difference is manufacturer origin. The Focus LCDs modules (E28RA-FW480-N and E28RA-I-CW480-N) offer additional SPI interface capability alongside the parallel interface. Viewing area dimensions vary slightly but remain within acceptable tolerances for display module applications. All three substitute parts maintain identical screen size, resolution, and color format specifications.

Q: Are the viewing area differences between INT028ATFT and Focus LCDs modules significant? A: The viewing area variations (approximately 1.6mm to 2.65mm differences in width and height) are minor and fall within standard mechanical tolerances for display module design. These differences do not affect electrical compatibility or functional performance in parallel interface applications.

Q: What packaging formats are available for these substitute parts? A: DT028ATFT is supplied in bulk packaging. E28RA-FW480-N and E28RA-I-CW480-N are supplied in box packaging. Packaging selection should be based on procurement and inventory management requirements.

Q: Are all substitute parts RoHS compliant? A: Yes. The INT028ATFT is RoHS compliant. All substitute parts (DT028ATFT, E28RA-FW480-N, E28RA-I-CW480-N) are ROHS3 compliant, meeting current regulatory standards.

Q: Which substitute part offers the best inventory availability? A: The DT028ATFT offers the highest inventory availability at 2400 units, followed by E28RA-FW480-N (895 units) and E28RA-I-CW480-N (757 units).
