MSD4110C 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The MSD4110C is a dual-character 7-segment LED display module manufactured by onsemi, featuring a 0.4-inch red LED display in a 16-DIP package configuration. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity. The display operates as a common anode configuration with a forward voltage of 2.1V and test current of 20mA, suitable for numeric and alphanumeric display applications requiring compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSD4110C is determined by the following critical parameters:

• Display Configuration: 2-character, 7-segment, common anode architecture
• Package Type: 16-DIP (0.500", 12.70mm) form factor
• Physical Dimensions: Nominal height 0.630", width approximately 0.795", depth 0.276"
• Digit Size: 0.40" (10.16mm) character height
• Color: Red LED emission
• Electrical Compatibility: Common anode pin configuration with forward voltage in the 2.0V to 2.1V range and test current specifications between 10mA and 20mA

The LDD-A404NI from Lumex Opto/Components Inc. qualifies as a substitute based on matching all critical parameters: identical character count, display type, common anode configuration, package designation, physical dimensions within tolerance, digit size, and red color specification. Electrical parameters (2.0V forward voltage, 10mA test current) fall within acceptable operating ranges for common anode 7-segment displays of this class.

Engineering Selection Recommendations

The LDD-A404NI represents a direct functional substitute for the obsolete MSD4110C. Selection is supported by the following factors:

• Product Status Alignment: The LDD-A404NI maintains active product status, ensuring ongoing availability and manufacturer support, whereas the MSD4110C is obsolete.
• Regulatory Compliance: Both components share identical REACH and ECCN classifications (REACH Unaffected, EAR99), confirming equivalent regulatory standing.
• Moisture Sensitivity: Both components specify MSL 1 (Unlimited), indicating identical handling and storage requirements.
• Mechanical Compatibility: Physical dimensions and 16-DIP package footprint are equivalent, enabling direct PCB layout compatibility without redesign.
• Electrical Operating Range: The LDD-A404NI operates within acceptable parameters for common anode 7-segment display applications, with forward voltage and test current specifications suitable for standard LED driver circuits designed for the MSD4110C.

Frequently Asked Questions (FAQ)

Q: Can the LDD-A404NI be used as a direct replacement for the MSD4110C without circuit modification?

A: Yes. Both components share identical package designation (16-DIP), pin configuration (common anode), and physical dimensions. No PCB layout changes are required. Circuit operation remains compatible with existing LED driver designs, though forward voltage and current specifications should be verified against your specific driver circuit parameters.

Q: What is the difference in wavelength between the MSD4110C (697nm) and LDD-A404NI (635nm)?

A: Both wavelengths fall within the red spectrum visible range. The MSD4110C emits at 697nm (deep red), while the LDD-A404NI emits at 635nm (standard red). Visual color appearance will differ slightly; the LDD-A404NI will appear brighter and more orange-toned. Evaluate this difference against your application's color requirements.

Q: Why does the LDD-A404NI specify 10mA test current while the MSD4110C specifies 20mA?

A: Test current specifications define the measurement conditions for optical and electrical characterization. The LDD-A404NI achieves higher brightness (3.9mcd versus 0.8mcd) at lower test current, indicating superior LED efficiency. Your circuit design should accommodate the LDD-A404NI's actual operating current requirements based on your specific brightness and power consumption targets.

Q: Are there any compliance or certification differences between these components?

A: No. Both components share identical REACH status (REACH Unaffected), ECCN classification (EAR99), HTSUS code (8541.41.0000), and Moisture Sensitivity Level (MSL 1 - Unlimited). Regulatory and compliance requirements are equivalent.

Q: What are the physical dimension tolerances between the two components?

A: Width differs by 0.1mm (0.795" versus 0.791"), and depth differs by 0.1mm (0.276" versus 0.276" - effectively identical). Height is identical at 0.630". These variations are within standard manufacturing tolerances for DIP package components and do not affect PCB compatibility or mechanical fit.
