LOD-H02002DP-W OLED Character Display Module - Equivalent & Substitute Parts

Part Overview

The LOD-H02002DP-W is a 40-character passive OLED display module manufactured by Lumex Opto/Components Inc. in a 20 x 2 character format with 5 x 8 dot resolution. This module operates as an active product with full RoHS3 compliance and is designed for parallel 8-bit interface applications requiring low-voltage operation between 2.4V and 5.5V.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits alternative display modules meeting equivalent electrical and mechanical specifications. The substitute identified maintains core functional parameters while introducing variations in physical dimensions, interface options, and color characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the LOD-H02002DP-W is based on strict equivalence across the following critical parameters:

Mandatory Match Parameters:

• Number of Characters: 40
• Display Format: 20 x 2
• Character Format: 5 x 8 Dots
• Display Type: OLED
• Display Mode: Passive
• Operating Temperature Range: -40°C ~ 80°C minimum
• Product Status: Active
• RoHS3 Compliance: Required

Allowable Variation Parameters:

• Voltage Supply Range: Substitute range (3V ~ 5.3V) overlaps with primary part range (2.4V ~ 5.5V) at 3V ~ 5.3V
• Interface: Substitute supports Parallel/Serial; primary requires Parallel 8-Bit (Parallel mode is compatible)
• Physical Dimensions: Substitute height (9.80mm) differs from primary (3.80mm); length and width match (116.00mm x 37.00mm)
• Text/Background Color: Substitute displays Yellow on Black; primary displays White on Black
• Viewing Area: Substitute (85.00mm L x 18.60mm W) differs from primary (75.52mm L x 13.52mm W)
• Character Size: Substitute (5.55mm H x 3.20mm W) approximates primary (5.57mm H x 3.22mm W)
• Dot Size: Substitute (0.60mm W x 0.65mm H) approximates primary (0.62mm W x 0.67mm H)

The substitute part NHD-0220DZW-AY5 qualifies as an equivalent because it maintains all mandatory parameters while introducing acceptable variations in non-critical dimensions and interface flexibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (LOD-H02002DP-W): Select the primary part when design specifications explicitly require white text display, minimum profile height (3.80mm), or when the lower voltage floor of 2.4V is necessary for power-constrained applications. The primary part maintains active product status with full RoHS3 and REACH compliance.

Substitute Part Selection (NHD-0220DZW-AY5): Select the substitute part when the primary part is unavailable or when design requirements permit yellow text display and increased module height (9.80mm). The substitute maintains equivalent electrical performance within the overlapping voltage range (3V ~ 5.3V) and supports both parallel and serial interface modes, providing additional design flexibility. Both parts maintain active product status and identical regulatory compliance (RoHS3, REACH Unaffected, EAR99 classification).

Voltage Supply Consideration: Applications requiring operation below 3V must use the primary part (LOD-H02002DP-W). Applications operating at 3V or above may use either part within the overlapping range.

Interface Consideration: The primary part requires parallel 8-bit interface operation. The substitute supports both parallel and serial modes; when used as a substitute, configure for parallel mode to maintain functional equivalence.

Mechanical Fit Consideration: The substitute part is 6.00mm taller (9.80mm vs. 3.80mm). Verify enclosure and mounting space accommodates this height difference before substitution.

Color Display Consideration: The substitute displays yellow characters on black background, while the primary displays white characters on black background. Verify application requirements do not mandate white text before substitution.

Frequently Asked Questions (FAQ)

Q: Can NHD-0220DZW-AY5 be used as a direct replacement for LOD-H02002DP-W?

A: NHD-0220DZW-AY5 qualifies as a substitute when three conditions are met: (1) the application operates at supply voltages of 3V or above, (2) the enclosure accommodates the increased height of 9.80mm, and (3) yellow text display is acceptable. If any condition is not met, the primary part is required.

Q: What is the voltage compatibility between these parts?

A: The primary part operates from 2.4V to 5.5V. The substitute operates from 3V to 5.3V. Both parts function within the overlapping range of 3V to 5.3V. Applications requiring operation below 3V must use the primary part exclusively.

Q: Are the physical dimensions compatible for PCB mounting?

A: Both parts share identical length (116.00mm) and width (37.00mm). The substitute is 6.00mm taller (9.80mm vs. 3.80mm). Verify the mounting location and enclosure height before substitution. The viewing areas differ: primary (75.52mm L x 13.52mm W) versus substitute (85.00mm L x 18.60mm W).

Q: Can the substitute operate in serial mode while the primary requires parallel mode?

A: The substitute supports both parallel and serial interface modes. When used as a substitute for the primary part, configure the substitute for parallel 8-bit mode to maintain functional equivalence. Serial mode operation would require different firmware and is not a substitute configuration.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, classified as EAR99, and share the same HTSUS code (8531.20.0020). Both maintain active product status with ongoing manufacturer support.

Q: What is the difference in character and dot size between these parts?

A: Character sizes are equivalent: primary (5.57mm H x 3.22mm W) versus substitute (5.55mm H x 3.20mm W). Dot sizes are equivalent: primary (0.62mm W x 0.67mm H) versus substitute (0.60mm W x 0.65mm H). These minor variations do not affect functional display performance.

Q: Why does the substitute have a larger viewing area?

A: The substitute viewing area (85.00mm L x 18.60mm W) is larger than the primary (75.52mm L x 13.52mm W). This results from different module construction and does not affect character count or display format. Both display 40 characters in 20 x 2 format.

Q: Is packaging different between these parts?

A: The primary part packaging is listed as "-" (not specified). The substitute is packaged in Tray format. Verify packaging requirements for your procurement and assembly processes.

Q: Can I use the substitute if my application requires white text?

A: No. The substitute displays yellow text on black background. The primary part displays white text on black background. If white text is a functional requirement, use the primary part exclusively.

Q: What is the moisture sensitivity level for each part?

A: The primary part has MSL 1 (Unlimited). The substitute has MSL listed as Not Applicable. Both parts have minimal moisture sensitivity concerns for standard handling and storage.
