MDLS-16265-SS-LV-S Equivalent & Substitute Parts

Part Overview

The MDLS-16265-SS-LV-S is a 16 x 2 character display module manufactured by Varitronix, featuring a reflective STN (Super-Twisted Nematic) LCD with 5 x 8 dot character format and parallel interface. This module operates at 5V supply voltage without backlight capability. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations where this display type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MDLS-16265-SS-LV-S is determined by the following critical parameters:

• Display Format: 16 x 2 character configuration
• Character Format: 5 x 8 dot matrix
• Display Type: STN - Super-Twisted Nematic technology
• Supply Voltage: 5V operation
• Interface: Parallel communication protocol
• Number of Characters: 32 total

The MDLS-16263-C-LV-G-LED01G-FFC qualifies as a substitute based on matching display format (16 x 2), character format (5 x 8 dots), display type (STN), supply voltage (5V), and parallel interface. Differences exist in display mode (transflective vs. reflective), backlight capability (LED green vs. none), physical dimensions, and operating temperature range. These differences represent functional enhancements rather than incompatibilities with the core display architecture.

Engineering Selection Recommendations

The MDLS-16263-C-LV-G-LED01G-FFC is the designated substitute for the obsolete MDLS-16265-SS-LV-S. Selection of this substitute is supported by the following factors:

• Active product status ensures ongoing availability and manufacturer support
• RoHS3 compliance meets current environmental and regulatory requirements
• Identical core display architecture (16 x 2 STN, 5 x 8 dots, parallel interface, 5V operation)
• Enhanced operating temperature range (-10°C ~ 60°C vs. -5°C ~ 50°C) provides broader environmental compatibility
• Transflective display mode with LED green backlight offers improved visibility in varied lighting conditions compared to reflective-only operation
• Smaller physical footprint (53.00mm x 20.00mm x 8.00mm vs. 80.00mm x 36.00mm x 13.00mm) accommodates space-constrained applications

Physical dimension differences require mechanical redesign of mounting and housing. Backlight presence necessitates additional power supply considerations for LED operation. These modifications are standard engineering practice when transitioning from obsolete to active components.

Frequently Asked Questions (FAQ)

Q: Can the MDLS-16263-C-LV-G-LED01G-FFC directly replace the MDLS-16265-SS-LV-S without modifications?

A: Direct pin-for-pin replacement is possible due to identical parallel interface and 5V supply voltage. However, mechanical redesign is required due to different physical dimensions. The presence of LED backlight in the substitute requires additional power supply design for the backlight circuit, which was absent in the original reflective module.

Q: What are the key differences between reflective and transflective display modes?

A: The MDLS-16265-SS-LV-S uses reflective mode, which relies entirely on ambient light reflection for visibility. The MDLS-16263-C-LV-G-LED01G-FFC uses transflective mode with LED backlight, allowing operation in both high ambient light conditions (using reflection) and low light conditions (using backlight illumination). This provides operational flexibility across varying environmental lighting.

Q: Are there compatibility concerns with the operating temperature ranges?

A: The substitute operates across a wider temperature range (-10°C ~ 60°C vs. -5°C ~ 50°C). Applications within the original range (-5°C ~ 50°C) are fully compatible. Applications requiring operation below -5°C or above 50°C benefit from the extended range of the substitute.

Q: What packaging considerations apply to this substitution?

A: The original MDLS-16265-SS-LV-S is packaged in standard format. The substitute MDLS-16263-C-LV-G-LED01G-FFC is packaged in boxes. Inventory availability differs significantly (811 pcs vs. 2478 pcs), with the substitute offering greater stock availability for procurement planning.

Q: Does the smaller physical footprint of the substitute create any compatibility issues?

A: The substitute is physically smaller (53.00mm x 20.00mm x 8.00mm vs. 80.00mm x 36.00mm x 13.00mm). Mechanical redesign of mounting brackets, housing, and panel cutouts is required. The reduced size may enable more compact system designs or require adapter plates for existing mechanical interfaces.

Q: What compliance certifications apply to the substitute?

A: The MDLS-16263-C-LV-G-LED01G-FFC is RoHS3 compliant and carries ECCN EAR99 classification, meeting current environmental and export control requirements. Both parts share identical HTSUS classification (8531.20.0020).
