Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the E1271CS021 is determined by strict equivalence across the following critical parameters:

• Display Technology: TFT - Electronic Paper Display (EPD)
• Physical Dimensions: 2.7" (68.58mm) diagonal screen size
• Resolution: 264 x 176 pixel array
• Display Characteristics: Reflective mode, black graphics on white background
• Communication Protocol: SPI interface
• Power Requirements: Without backlight operation
• Environmental Rating: MSL 1 (Unlimited moisture sensitivity)

The E2271CS021 qualifies as a direct substitute based on complete alignment across all specified parameters. Both parts share identical display specifications, resolution, interface protocol, and environmental ratings, ensuring functional and mechanical compatibility in applications originally designed for the E1271CS021.

Parameter Comparison

Engineering Selection Recommendations

The E2271CS021 is the designated substitute for the obsolete E1271CS021. Both components are no longer in active production; however, the E2271CS021 maintains ROHS3 compliance certification, which provides regulatory advantage for applications subject to environmental and hazardous substance restrictions. The E2271CS021 is currently available in higher inventory quantities (1,281 units) compared to the E1271CS021 (974 units), supporting supply chain continuity for replacement and maintenance applications.

Selection of the E2271CS021 is appropriate for direct replacement in existing designs and for new implementations requiring 2.7" reflective EPD technology with SPI interface and 264 x 176 resolution. No design modifications are required due to complete parameter equivalence.

Frequently Asked Questions (FAQ)

Q: Can the E2271CS021 be used as a direct replacement for the E1271CS021?

A: Yes. Both parts are identical in display specifications, resolution, interface protocol, viewing area, and environmental ratings. Direct substitution is supported without design changes.

Q: What are the key differences between E1271CS021 and E2271CS021?

A: The primary differences are product status and compliance certification. The E2271CS021 is ROHS3 compliant, while the E1271CS021 status does not specify compliance. Both parts share identical electrical and mechanical specifications.

Q: Are there packaging differences between these parts?

A: The E2271CS021 is supplied in Box packaging. The E1271CS021 packaging specification is not provided in the technical data.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying logistics and inventory management.

Q: Why is the E1271CS021 classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Pervasive Displays. The E2271CS021 serves as the current equivalent for ongoing supply and support.

Q: Is the SPI interface compatible with standard microcontroller implementations?

A: SPI is a standard serial communication protocol supported by most microcontrollers and embedded systems. Interface compatibility depends on the specific host system implementation, not on the display module itself.
