LOD-H02004DP-G OLED Character Display Module - Equivalent & Substitute Parts

Part Overview

The LOD-H02004DP-G is a passive OLED character display module manufactured by Lumex Opto/Components Inc. This 20 x 4 character display module features an 80-digit capacity with 5 x 8 dot character format, designed for parallel 8-bit interface applications. The module operates across a supply voltage range of 2.4V to 5.5V and maintains active product status with full RoHS3 compliance.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design requirements permit alternative form factors or interface configurations while maintaining core functional parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LOD-H02004DP-G is determined by strict alignment with the following core parameters:

Display Capacity and Format: The substitute part must provide 80 characters in a 20 x 4 configuration with 5 x 8 dot character format. These parameters define the functional display output and cannot be altered without affecting system compatibility.

Display Technology: Both the main part and substitute must utilize OLED display technology in passive display mode. This ensures equivalent electrical behavior and optical performance.

Operating Voltage: The substitute part must operate within a voltage range that overlaps with or is contained within the main part's 2.4V to 5.5V supply range. The substitute NHD-0420DZW-AG5 operates at 3V to 5.3V, which is compatible with typical system supplies within the main part's range.

Interface Configuration: The main part specifies parallel 8-bit interface. The substitute part supports both parallel and serial interfaces, allowing parallel 8-bit operation equivalent to the main part.

Operating Temperature Range: Both parts must support the -40°C to 80°C operating temperature range required by the application.

Color Output: Text color (green) and background color (black) must match to maintain visual consistency in the application.

Regulatory Compliance: Both parts must maintain RoHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration - Mechanical Fit: The substitute part NHD-0420DZW-AG5 has a height of 10.00mm compared to the main part's 2.20mm. This 7.80mm height difference requires verification against mechanical constraints in the target application. If the application has height restrictions or mounting clearance limitations, this difference must be evaluated before selection.

Electrical Compatibility: Both parts operate within overlapping voltage ranges and support the required -40°C to 80°C temperature range. The substitute part's voltage range (3V to 5.3V) is fully contained within the main part's range (2.4V to 5.5V), ensuring electrical compatibility with standard system supplies.

Interface Flexibility: The substitute part supports both parallel and serial interfaces. When configured for parallel 8-bit operation, it provides functional equivalence to the main part's dedicated parallel 8-bit interface.

Regulatory Compliance: Both parts maintain active product status, RoHS3 compliance, and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

Viewing Area: The substitute part provides a larger viewing area (77.00mm x 25.20mm versus 72.42mm x 22.82mm), which may offer improved visibility in certain applications.

Frequently Asked Questions (FAQ)

Q: Can the NHD-0420DZW-AG5 directly replace the LOD-H02004DP-G in existing designs?

A: Functional replacement is possible when the substitute is configured for parallel 8-bit operation. However, the 7.80mm height difference must be verified against mechanical constraints, mounting requirements, and PCB layout specifications before implementation.

Q: Are the character sizes equivalent between these two parts?

A: Character sizes are equivalent within engineering tolerance. The main part specifies 4.77mm H x 2.97mm W, while the substitute specifies 4.75mm H x 2.90mm W. These differences are negligible for display applications.

Q: What is the impact of the substitute part's larger viewing area?

A: The substitute part's viewing area (77.00mm x 25.20mm) is larger than the main part (72.42mm x 22.82mm). This provides a wider field of view and may improve visibility. This difference does not affect electrical compatibility but should be considered in mechanical layout planning.

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

A: Yes. Both parts operate across the -40°C to 80°C temperature range, ensuring equivalent thermal performance in the target application environment.

Q: What interface configuration should be used for the substitute part?

A: The substitute part NHD-0420DZW-AG5 supports both parallel and serial interfaces. For direct functional replacement of the LOD-H02004DP-G, configure the substitute for parallel 8-bit operation to match the main part's interface specification.

Q: Are there any regulatory compliance differences between these parts?

A: No. Both parts maintain RoHS3 compliance and REACH unaffected status, ensuring equivalent regulatory compliance for component selection.

Q: How do the voltage supply ranges compare?

A: The main part operates at 2.4V to 5.5V, while the substitute operates at 3V to 5.3V. The substitute's range is fully contained within the main part's range, ensuring compatibility with standard system supplies.

Q: What packaging differences exist between these parts?

A: The main part packaging is specified as "-" (not detailed), while the substitute is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.
