Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DT028ATFT-PTS is determined by the following critical parameters:

Primary Compatibility Criteria:

• Diagonal screen size: 2.8" (71.12mm)
• Display type: TFT - Color with transmissive mode
• Touchscreen technology: Capacitive
• Viewing area dimensions: 43.20mm W x 57.60mm H
• Graphics color capability: Red, Green, Blue (RGB)
• Backlight type: LED
• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

Secondary Consideration:

• Interface type and pixel resolution may vary within acceptable design parameters depending on system architecture

The DT028BTFT-PTS2 qualifies as a substitute component based on matching the primary compatibility criteria. While the interface differs (Parallel 18-Bit RGB versus I2C) and pixel resolution is transposed (320 x 240 versus 240 x 320), both parameters remain within the scope of acceptable substitution for the DT028 base product family.

Parameter Comparison

Engineering Selection Recommendations

The DT028BTFT-PTS2 is the qualified substitute for the obsolete DT028ATFT-PTS. Both components share identical physical dimensions, display technology, and environmental compliance ratings. The DT028BTFT-PTS2 maintains active product status with significantly higher inventory availability (3546 units versus 649 units), ensuring supply chain continuity.

Interface and resolution differences require system-level evaluation. The DT028ATFT-PTS uses I2C serial communication with 240 x 320 pixel configuration, while the DT028BTFT-PTS2 employs parallel 18-bit RGB interface with 320 x 240 pixel resolution. Both configurations support full RGB color graphics and capacitive touch functionality. Selection between these variants depends on host system interface capabilities and display orientation requirements.

Both components meet RoHS compliance and carry identical moisture sensitivity ratings, confirming environmental suitability for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the DT028BTFT-PTS2 directly replace the DT028ATFT-PTS without modifications?

A: Physical and environmental compatibility is confirmed. However, interface protocol differences (I2C versus parallel 18-bit RGB) and pixel resolution orientation (240 x 320 versus 320 x 240) require firmware and hardware interface adaptation. Direct pin-for-pin replacement is not possible.

Q: What are the key physical compatibility factors?

A: Both modules share identical diagonal screen size (2.8 inches / 71.12mm), viewing area dimensions (43.20mm W x 57.60mm H), and mechanical form factor. Physical mounting and display area compatibility is confirmed.

Q: Are there environmental or compliance concerns with substitution?

A: Both components are RoHS compliant and carry identical moisture sensitivity level ratings (MSL 1 - Unlimited). No environmental or regulatory barriers to substitution exist.

Q: How do the interface differences affect system integration?

A: The DT028ATFT-PTS uses I2C serial interface, requiring minimal pin count and supporting lower bandwidth applications. The DT028BTFT-PTS2 uses parallel 18-bit RGB interface, requiring more I/O pins but supporting higher refresh rates and real-time graphics updates. Host system architecture determines which interface is appropriate.

Q: What is the significance of the pixel resolution difference?

A: The DT028ATFT-PTS provides 240 x 320 resolution (portrait orientation), while the DT028BTFT-PTS2 provides 320 x 240 resolution (landscape orientation). Display content and graphics rendering must be adapted accordingly. Both resolutions support equivalent information density for 2.8-inch display applications.

Q: Why is the DT028BTFT-PTS2 recommended despite being a different model?

A: The DT028BTFT-PTS2 shares the DT028 base product family designation, confirming design compatibility within the Displaytech product line. Active product status ensures ongoing availability and support, addressing the obsolescence of the DT028ATFT-PTS.
