Key Parameters

Substitute Part Grouping Explanation

Substitution of the OLED0821-OB is determined by strict equivalence across the following critical parameters:

• Display resolution and format (16 characters, 8 x 2 configuration)
• Character dot matrix (5 x 8 dots)
• Display technology (OLED, transmissive mode)
• Physical dimensions (58.00mm x 32.00mm x 22.40mm)
• Electrical specifications (4.75V ~ 5.25V supply voltage)
• Communication interfaces (I2C, RS-232, TTL support)
• Operating temperature range (-20°C ~ 70°C)

The OLED0821-OW qualifies as a direct substitute based on identical alignment across all these parameters. The primary distinction between the two parts is the text color output: the OLED0821-OB displays blue text, while the OLED0821-OW displays white text. Both parts share the same base product number (OLED0821) and maintain identical mechanical and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The OLED0821-OW is the appropriate substitute for the obsolete OLED0821-OB. Both parts maintain identical mechanical and electrical specifications, ensuring direct compatibility in existing designs. The OLED0821-OW holds active product status, providing ongoing availability and supply chain stability compared to the obsolete OLED0821-OB.

The OLED0821-OW carries RoHS compliance certification, meeting current regulatory requirements for electronic components in many jurisdictions. Both parts share identical moisture sensitivity levels and export classification codes, confirming equivalent handling and regulatory treatment.

The sole functional difference is text color output: blue for the OLED0821-OB versus white for the OLED0821-OW. This distinction should be evaluated based on application-specific visibility and contrast requirements within the target system environment.

Frequently Asked Questions (FAQ)

Q: Can the OLED0821-OW directly replace the OLED0821-OB in existing applications?

A: Yes. The OLED0821-OW provides direct mechanical and electrical compatibility. Both parts share identical dimensions, pinout, voltage specifications, and communication interfaces. The only difference is text color output.

Q: What is the primary reason for substitution?

A: The OLED0821-OB is classified as obsolete. The OLED0821-OW is an active product from the same manufacturer with identical specifications, ensuring continued availability and supply chain support.

Q: Are there packaging differences between these parts?
