Key Parameters

Substitute Part Grouping Explanation

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

• Display Configuration: 16 characters, 8 x 2 format, 5 x 8 dot character matrix
• Display Technology: OLED transmissive type
• Physical Dimensions: 58.00mm x 32.00mm x 22.40mm outline
• Electrical Interface: I2C, RS-232, TTL communication protocols
• Power Supply: 4.75V ~ 5.25V operating voltage
• Operating Temperature: -20°C ~ 70°C range
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The OLED0821-OY meets all these critical parameters and qualifies as a direct substitute. The primary distinction is product status (active versus obsolete) and text color output (yellow versus green), which do not affect functional compatibility or electrical performance in applications where the display format and interface requirements are the determining factors.

Parameter Comparison

Engineering Selection Recommendations

The OLED0821-OY is the qualified substitute for the obsolete OLED0821-OG. Selection of the OLED0821-OY is supported by the following engineering criteria:

Product Status: The OLED0821-OY maintains active product status with confirmed inventory availability (987 Pcs), ensuring long-term supply chain reliability compared to the obsolete OLED0821-OG.

Compliance: The OLED0821-OY carries RoHS Compliant certification and EAR99 ECCN classification, meeting current regulatory requirements for electronic component procurement and export control compliance.

Functional Equivalence: All critical electrical, mechanical, and interface parameters are identical between the two parts. The OLED0821-OY operates within the same voltage supply range (4.75V ~ 5.25V), supports identical communication protocols (I2C, RS-232, TTL), and maintains the same physical form factor and operating temperature range (-20°C ~ 70°C).

Color Differentiation: The OLED0821-OY produces yellow text output compared to the green output of the OLED0821-OG. This distinction is a visual characteristic only and does not affect electrical compatibility, signal integrity, or functional performance in applications where alphanumeric display capability is the primary requirement.

Frequently Asked Questions (FAQ)

Q: Can the OLED0821-OY directly replace the OLED0821-OG in existing designs?

A: Yes. The OLED0821-OY is electrically and mechanically equivalent to the OLED0821-OG. Both parts share identical display format (16 characters, 8 x 2), physical dimensions (58.00mm x 32.00mm x 22.40mm), power supply requirements (4.75V ~ 5.25V), and communication interfaces (I2C, RS-232, TTL). No circuit modifications or firmware changes are required for substitution.

Q: What is the difference between the OLED0821-OG and OLED0821-OY?

A: The primary differences are product status and text color. The OLED0821-OG is obsolete with green text output, while the OLED0821-OY is active with yellow text output. Both parts are otherwise functionally identical in terms of electrical performance, interface capability, and physical specifications.

Q: Are there packaging differences between these parts?

A: The OLED0821-OG packaging is not specified in available documentation. The OLED0821-OY is supplied in Bulk packaging. Confirm packaging requirements with your procurement specification before finalizing component selection.

Q: Does the OLED0821-OY meet current compliance standards?

A: Yes. The OLED0821-OY is RoHS Compliant and carries EAR99 ECCN classification, meeting current regulatory requirements for electronic component use and export control compliance.

Q: What is the operating temperature range for both parts?

A: Both the OLED0821-OG and OLED0821-OY operate within the temperature range of -20°C to 70°C. This specification is identical for both parts and does not affect substitution eligibility.

Q: Are both parts rated for unlimited moisture exposure?

A: Both parts carry Moisture Sensitivity Level (MSL) 1 classification, which indicates unlimited moisture sensitivity rating. Standard handling and storage practices for electronic components apply.
