Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OK202-25-OG-V is determined by the following critical parameters:

• Display Configuration: 40 characters in 20 x 2 format
• Display Technology: OLED type
• Physical Dimensions: 116.00mm x 37.00mm x 25.00mm (outline); 85.00mm x 18.60mm (viewing area)
• Character Size: 5.55mm H x 3.20mm W
• Electrical Interface: I2C, RS-232, TTL support
• Voltage Supply Range: 9V ~ 15V
• Operating Temperature Range: -20°C ~ 70°C
• Dot Size: 0.60mm W x 0.65mm H

The OK202-25-OY-V qualifies as a direct substitute based on identical values across all critical parameters listed above. The primary difference is text color (yellow instead of green) and product status (active instead of obsolete).

Parameter Comparison

Engineering Selection Recommendations

The OK202-25-OY-V is the direct substitute for the OK202-25-OG-V. Selection between these parts should be based on the following factors:

For New Designs and Replacements: The OK202-25-OY-V is the recommended choice. This part carries active product status, ensuring ongoing manufacturer support and availability. The part is RoHS compliant, meeting current environmental and regulatory standards. Current inventory of 697 units is available.

For Legacy System Maintenance: If the original green text display (OK202-25-OG-V) is functionally required and cannot be substituted with yellow text, the obsolete status of the original part necessitates immediate procurement planning. Current inventory of 1,157 units of the OK202-25-OG-V remains available.

Color Consideration: The only functional difference between these parts is display text color. Green text (OK202-25-OG-V) versus yellow text (OK202-25-OY-V) does not affect electrical performance, interface compatibility, or mechanical fit. Selection should be based on application visibility requirements and user interface design specifications.

Frequently Asked Questions (FAQ)

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

A: Yes. The OK202-25-OY-V is electrically and mechanically identical to the OK202-25-OG-V. All electrical parameters, interface protocols, physical dimensions, and operating ranges are identical. The only difference is display text color (yellow versus green). No circuit modifications or firmware changes are required for substitution.

Q: What is the significance of the product status difference?

A: The OK202-25-OG-V is listed as obsolete, indicating that Matrix Orbital has discontinued manufacturing and support for this specific part number. The OK202-25-OY-V maintains active product status, ensuring continued availability, manufacturer technical support, and compliance with current standards. For new designs, the active part is the appropriate choice.

Q: Are there packaging differences between these parts?

A: The OK202-25-OG-V is specified with packaging listed as "-" (not specified). The OK202-25-OY-V is supplied in bulk packaging. Both parts share identical physical dimensions and mechanical specifications.

Q: Does the RoHS compliance difference affect substitution?

A: The OK202-25-OY-V is RoHS compliant. The OK202-25-OG-V RoHS status is not specified in available documentation. For applications requiring RoHS compliance certification, the OK202-25-OY-V is the appropriate selection.

Q: Are the communication interfaces identical?

A: Yes. Both parts support I2C, RS-232, and TTL interfaces with identical electrical specifications. No interface adapter or protocol conversion is required for substitution.
