Substitute Part Grouping Explanation

Substitution eligibility for the OLED0821-OG-V is determined by strict equivalence across the following critical parameters:

• Number of Characters: 16
• Display Format: 8 x 2
• Character Format: 5 x 8 Dots
• Display Type: OLED
• Display Mode: Transmissive
• Outline Dimensions: 58.00mm x 32.00mm x 22.40mm
• Voltage - Supply: 4.75V ~ 5.25V
• Interface: I2C, RS-232, TTL
• Operating Temperature: -20°C ~ 70°C
• Character Size: 5.56mm H x 2.96mm W
• Dot Size: 0.56mm W x 0.66mm H
• Viewing Area: 38.00mm L x 16.00mm W

The OLED0821-OY-V meets all substitution criteria. This part maintains identical electrical specifications, mechanical dimensions, character display parameters, and communication interfaces. The primary difference is text color (yellow versus green) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The OLED0821-OY-V is a direct functional substitute for the obsolete OLED0821-OG-V. Both parts share identical electrical characteristics, mechanical form factors, and communication protocols. The substitute part is currently in active production status, ensuring ongoing availability and supply chain continuity.

The OLED0821-OY-V carries RoHS compliance certification, meeting environmental and regulatory requirements for modern manufacturing and distribution. The primary design consideration is the text color difference: yellow text versus green text. This distinction is purely visual and does not affect electrical performance, interface compatibility, or mechanical integration.

Selection of the OLED0821-OY-V is appropriate for applications where the original green-text display is no longer available and yellow-text output is acceptable within system requirements.

Frequently Asked Questions (FAQ)

Q: Are the OLED0821-OG-V and OLED0821-OY-V electrically interchangeable?

A: Yes. Both parts operate at identical supply voltages (4.75V to 5.25V), support the same communication interfaces (I2C, RS-232, TTL), and function across the same operating temperature range (-20°C to 70°C). No circuit modifications are required for substitution.

Q: What is the difference between these two parts?

A: The primary difference is text color. The OLED0821-OG-V displays green text, while the OLED0821-OY-V displays yellow text. All other specifications—character count, display format, dimensions, electrical ratings, and interfaces—are identical.

Q: Are the mechanical dimensions identical?

A: Yes. Both parts have identical outline dimensions (58.00mm x 32.00mm x 22.40mm), viewing area (38.00mm L x 16.00mm W), and character size (5.56mm H x 2.96mm W). Direct mechanical replacement is possible without PCB redesign.

Q: Does the OLED0821-OY-V meet RoHS compliance?

A: Yes. The OLED0821-OY-V is RoHS compliant. RoHS compliance status for the original OLED0821-OG-V is not specified in available documentation.

Q: What is the packaging difference?

A: The OLED0821-OG-V packaging is not specified. The OLED0821-OY-V is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Can I use the OLED0821-OY-V in applications requiring green text output?

A: No. The OLED0821-OY-V produces yellow text. If green text is a functional requirement, this substitute is not suitable. Verify that yellow text output is acceptable for your application before proceeding with substitution.
