Substitute Part Grouping Explanation

The OK162-12-OW serves as an equivalent substitute for the OK162-12-OB based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• Display Format: 16 x 2 (identical character count and layout)
• Display Type: OLED (same display technology)
• Character Size: 5.55mm H x 2.95mm W (identical character dimensions)
• Outline Dimensions: 80.00mm x 36.00mm x 25.10mm (identical physical footprint)
• Viewing Area: 66.00mm L x 16.00mm W (identical viewing dimensions)
• Dot Size: 0.55mm W x 0.65mm H (identical pixel dimensions)
• Interface: I2C, RS-232, TTL (identical communication protocols)
• Operating Temperature: -20°C ~ 70°C (identical temperature range)
• Background Color: Black (identical background)
• Moisture Sensitivity Level: 1 (Unlimited) (identical MSL rating)

Differences:

• Text Color: Blue (OK162-12-OB) vs. White (OK162-12-OW)
• Voltage Supply: 5V fixed (OK162-12-OB) vs. 4.75V ~ 5.25V range (OK162-12-OW)
• Product Status: Obsolete (OK162-12-OB) vs. Active (OK162-12-OW)
• Packaging: Not specified (OK162-12-OB) vs. Bulk (OK162-12-OW)
• RoHS Status: Not specified (OK162-12-OB) vs. RoHS Compliant (OK162-12-OW)

Parameter Comparison

Engineering Selection Recommendations

The OK162-12-OW is the active equivalent for the obsolete OK162-12-OB. Selection between these parts should be based on the following factors:

For Direct Replacement (OK162-12-OB to OK162-12-OW): The OK162-12-OW maintains identical mechanical and electrical interface specifications, making it suitable for direct substitution in applications currently using the OK162-12-OB. The primary consideration is the text color difference: the OK162-12-OW displays white text instead of blue. Verify that display color change does not impact system requirements or user interface specifications.

Voltage Supply Consideration: The OK162-12-OB operates at a fixed 5V supply, while the OK162-12-OW accepts a 4.75V to 5.25V range. This expanded voltage tolerance in the OK162-12-OW provides greater flexibility in power supply design and improved compatibility with systems subject to voltage fluctuations.

Product Status and Compliance: The OK162-12-OW carries active product status and RoHS compliance certification, ensuring ongoing manufacturer support and regulatory alignment for new designs and long-term system maintenance.

Frequently Asked Questions (FAQ)

Q: Can the OK162-12-OW directly replace the OK162-12-OB in existing designs? A: Yes, the OK162-12-OW is mechanically and electrically compatible with the OK162-12-OB. Both modules share identical display format (16x2), physical dimensions (80.00mm x 36.00mm x 25.10mm), character size, viewing area, dot size, and communication interfaces (I2C, RS-232, TTL). The primary difference is text color: white (OK162-12-OW) versus blue (OK162-12-OB). Confirm that this color change does not conflict with system requirements.

Q: What is the significance of the voltage supply difference between these parts? A: The OK162-12-OB specifies a fixed 5V supply, while the OK162-12-OW accepts 4.75V to 5.25V. The expanded voltage tolerance of the OK162-12-OW provides improved robustness against power supply variations and is generally preferable for new designs. Both parts operate within standard 5V logic systems.

Q: Are there any packaging differences between OK162-12-OB and OK162-12-OW? A: The OK162-12-OB packaging is not specified in available documentation. The OK162-12-OW is supplied in Bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Does the OK162-12-OW meet RoHS compliance requirements? A: Yes, the OK162-12-OW is RoHS Compliant. The OK162-12-OB compliance status is not specified. For applications requiring RoHS certification, the OK162-12-OW is the appropriate selection.

Q: Are the operating temperature ranges identical? A: Yes, both the OK162-12-OB and OK162-12-OW operate across the same temperature range: -20°C to 70°C. No thermal performance differences exist between these parts.

Q: What communication interfaces are supported by the OK162-12-OW? A: The OK162-12-OW supports I2C, RS-232, and TTL interfaces, identical to the OK162-12-OB. All three communication protocols are available on a single module, providing flexibility in system integration.
