Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OK202-25-OG is determined by strict equivalence across the following critical parameters:

• Display Configuration: 20x2 character format with 40-digit capacity
• Display Technology: OLED type
• Physical Dimensions: Outline dimensions of 116.00mm x 37.00mm x 25.00mm
• Character Dimensions: 5.55mm H x 3.20mm W
• Electrical Supply: 4.75V ~ 5.25V operating range
• Communication Interfaces: I2C, RS-232, and TTL support
• Operating Temperature Range: -20°C ~ 70°C
• Viewing Area: 85.00mm L x 18.60mm W

The OK202-25-OY meets all substitution criteria. While it differs in text color (yellow versus green) and product status (active versus obsolete), these parameters do not affect functional compatibility or mechanical interchangeability in applications where the display color change is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The OK202-25-OY is a direct functional substitute for the OK202-25-OG. The primary distinction is product status: the OK202-25-OG is obsolete while the OK202-25-OY is active and currently in production. The OK202-25-OY carries RoHS Compliant certification and is assigned HTSUS code 8531.20.0020, indicating compliance with current regulatory standards.

For applications requiring the original green text display, the OK202-25-OG remains available in inventory (801 units). For new designs or long-term supply assurance, the OK202-25-OY with yellow text display is the recommended selection due to its active product status and regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the OK202-25-OY replace the OK202-25-OG in existing applications?

A: Yes. The OK202-25-OY is mechanically and electrically identical to the OK202-25-OG. The only difference is text color (yellow versus green). Substitution is valid provided the application can accommodate the yellow text display.

Q: What is the difference between the two parts?

A: The OK202-25-OG features green text on a black background and is obsolete. The OK202-25-OY features yellow text on a black background and is currently in active production with RoHS compliance certification.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical outline dimensions of 116.00mm x 37.00mm x 25.00mm and identical viewing areas of 85.00mm L x 18.60mm W.

Q: Do both parts support the same communication interfaces?

A: Yes. Both the OK202-25-OG and OK202-25-OY support I2C, RS-232, and TTL interfaces.

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

A: Both parts operate within the voltage range of 4.75V ~ 5.25V.

Q: Are there packaging differences between these parts?

A: The OK202-25-OG is packaged as standard, while the OK202-25-OY is supplied in bulk packaging.
