Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOS-AO162A-OB is determined by the following critical parameters:

• Display Format & Character Count: Must maintain 16 x 2 configuration with 32-character capacity
• Interface Compatibility: Must support RS232 and TTL serial communication protocols
• Physical Dimensions: Outline dimensions (80.00mm x 36.00mm x 23.97mm) and viewing area (66.00mm L x 16.00mm W) must match for mechanical fit
• Electrical Specifications: Supply voltage range 4.75V ~ 5.25V and operating temperature 0°C ~ 50°C must be maintained
• Character Specifications: Character size (5.55mm H x 2.95mm W) must remain consistent

The MOS-AO162A-OW qualifies as a direct substitute based on identical compliance with all critical parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The MOS-AO162A-OW is the direct active equivalent for the obsolete MOS-AO162A-OB. Both parts maintain identical electrical, mechanical, and functional specifications across all critical parameters. The primary distinction is product status: the MOS-AO162A-OB is obsolete, while the MOS-AO162A-OW is active and currently available.

The MOS-AO162A-OW carries RoHS Compliant certification, providing environmental compliance assurance for new designs and applications subject to regulatory requirements. The display color difference (white text on black background versus blue text on black background) represents the only functional variation and should be evaluated based on application visibility requirements.

Frequently Asked Questions (FAQ)

Q: Can the MOS-AO162A-OW directly replace the MOS-AO162A-OB in existing designs?

A: Yes. Both parts share identical display format (16 x 2), character count (32), interface protocols (RS232, TTL), electrical specifications (4.75V ~ 5.25V supply), operating temperature range (0°C ~ 50°C), and physical dimensions (80.00mm x 36.00mm x 23.97mm). Direct mechanical and electrical substitution is supported.

Q: What is the difference between these two models?

A: The primary differences are product status and display color. The MOS-AO162A-OB is obsolete with blue text on black background. The MOS-AO162A-OW is active with white text on black background and carries RoHS Compliant certification.

Q: Are there any compatibility concerns with the display color change?

A: Display color selection depends on application requirements for contrast, visibility, and ambient lighting conditions. Both configurations maintain identical character size (5.55mm H x 2.95mm W) and viewing area (66.00mm L x 16.00mm W). Evaluate color preference based on your specific application environment.

Q: Is the MOS-AO162A-OW suitable for new designs?

A: Yes. The MOS-AO162A-OW is active and carries RoHS Compliant certification, making it appropriate for new product development and applications subject to environmental compliance standards.

Q: Do both parts support the same communication protocols?

A: Yes. Both the MOS-AO162A-OB and MOS-AO162A-OW support RS232 and TTL serial interfaces, ensuring protocol compatibility across system implementations.
