Key Parameters

Substitute Part Grouping Explanation

Substitution of the OK204-25-USB-OG is determined by strict equivalence across the following critical parameters:

• Display resolution: 80 characters in 20 x 4 format
• Character dot matrix: 5 x 8 dots per character
• Display technology: OLED
• Communication interface: USB
• Supply voltage range: 4.75V ~ 5.25V
• Physical dimensions: 98.00mm x 60.00mm x 23.00mm
• Operating temperature range: -20°C ~ 70°C

The OK204-25-USB-OY meets all these criteria and is identified as a direct substitute. Differences in text color (green vs. yellow), background color consistency (black), packaging format (bulk vs. original), and product status (active vs. obsolete) do not affect functional compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The OK204-25-USB-OY is the appropriate substitute for the obsolete OK204-25-USB-OG. Selection of this substitute is justified on the following basis:

• The substitute maintains active product status, ensuring ongoing availability and manufacturer support.
• All electrical and mechanical parameters are identical, guaranteeing functional equivalence in circuit design and mechanical integration.
• The substitute is RoHS compliant, meeting current environmental and regulatory standards.
• The only functional difference is text color (yellow vs. green), which does not affect electrical performance or interface compatibility.
• Both modules share the same base product number (OK204-25), confirming design lineage and compatibility.

Frequently Asked Questions (FAQ)

Q: Can the OK204-25-USB-OY be used as a direct replacement for the OK204-25-USB-OG in existing designs?

A: Yes. The substitute maintains identical electrical specifications, USB interface protocol, supply voltage requirements, operating temperature range, and physical dimensions. No circuit modifications or mechanical redesign is required.

Q: What is the significance of the text color difference between the two modules?

A: Text color (green vs. yellow) is a visual characteristic that does not affect electrical performance, signal integrity, or interface compatibility. Selection between these variants depends on application-specific visibility requirements and user preference.

Q: Why is the OK204-25-USB-OG listed as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The OK204-25-USB-OY represents the active continuation of this product line and is the recommended source for new procurement.

Q: Does the RoHS compliance status of the OK204-25-USB-OY affect compatibility?

A: No. RoHS compliance is an environmental and regulatory attribute that does not alter electrical or mechanical compatibility. The substitute's compliance status makes it suitable for applications with regulatory requirements.

Q: Are there packaging differences between these two parts?

A: The OK204-25-USB-OG is specified with standard packaging, while the OK204-25-USB-OY is supplied in bulk packaging. This difference affects procurement and handling but does not impact component functionality or performance.

Q: What is the base product number, and why is it relevant?

A: Both modules share the base product number OK204-25. This designation indicates they are part of the same product family and confirms design compatibility and interchangeability.
