Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOS-AO202C-OG is determined by strict equivalence across the following critical parameters:

• Display Format & Character Count: 20 x 2 configuration with 40 total characters
• Display Type & Mode: Alphanumeric transmissive display
• Physical Dimensions: Outline and viewing area must match or be mechanically compatible
• Character Size: 5.55mm H x 3.20mm W
• Electrical Interface: RS232 and TTL serial communication support
• Voltage Supply: 4.75V ~ 5.25V operating range
• Operating Temperature: 0°C ~ 50°C range
• Mechanical Packaging: Identical form factor for direct replacement

The MOS-AO202C-OY meets all critical substitution criteria. While display color differs (yellow text instead of green), all functional, electrical, and mechanical parameters remain equivalent, enabling direct replacement in applications where color distinction is not a design constraint.

Parameter Comparison

Engineering Selection Recommendations

The MOS-AO202C-OY is a direct functional equivalent to the MOS-AO202C-OG. The primary distinction is product status: the original part is obsolete, while the substitute is active and currently in production.

The MOS-AO202C-OY carries RoHS compliance certification, meeting modern environmental and regulatory standards. This compliance status provides additional assurance for applications subject to RoHS requirements or future regulatory transitions.

All electrical, mechanical, and interface parameters are identical between the two parts. Selection of the MOS-AO202C-OY eliminates obsolescence risk while maintaining full functional compatibility with existing system designs.

Frequently Asked Questions (FAQ)

Q: Can the MOS-AO202C-OY replace the MOS-AO202C-OG in existing designs?

A: Yes. The MOS-AO202C-OY is a direct substitute. All critical parameters—display format, character count, physical dimensions, electrical interface, voltage supply, and operating temperature range—are identical. The only difference is display text color (yellow versus green).

Q: Are there any mechanical compatibility concerns?

A: No. Both parts share identical outline dimensions (116.00mm x 37.00mm x 23.77mm) and viewing area (85.00mm x 18.60mm). Direct mechanical replacement is supported without modification to mounting hardware or mechanical interfaces.

Q: Does the color difference affect electrical compatibility?

A: No. Display color is a visual characteristic only and does not impact electrical operation, signal processing, or interface compatibility. Both parts operate identically via RS232 and TTL serial communication.

Q: Is the MOS-AO202C-OY suitable for applications requiring RoHS compliance?

A: Yes. The MOS-AO202C-OY is RoHS compliant, making it suitable for applications and markets with RoHS requirements.

Q: What is the supply voltage requirement for both parts?

A: Both the MOS-AO202C-OG and MOS-AO202C-OY operate within the 4.75V to 5.25V supply range, supporting standard 5V logic systems.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the 0°C to 50°C temperature range, supporting identical thermal environments.
