MSD4440C 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The MSD4440C is a dual-character 7-segment LED display module manufactured by onsemi, featuring a 0.4" digit height with green color output and common cathode configuration. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The display operates at 2.1V forward voltage with 20mA test current and is housed in a 16-DIP package.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSD4440C is determined by strict alignment with the following electrical and mechanical parameters:

• Display Configuration: 2-character, 7-segment, common cathode topology
• Digit Height: 0.40" (10.16mm) nominal dimension
• Color Output: Green wavelength (565-574nm range acceptable)
• Electrical Operating Point: Forward voltage 2.05V to 2.2V; test current 10mA to 20mA
• Package Type: 16-DIP (0.500", 12.70mm) form factor
• Physical Dimensions: Height 0.630", width 0.795" to 0.866", depth 0.272" to 0.319"

All substitute parts listed below meet these core criteria and maintain functional and mechanical compatibility with the original MSD4440C specification.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components with ROHS3 compliance certification, providing long-term availability and regulatory alignment for new designs. The MSD4440C, being obsolete, should be replaced in active projects using one of the following alternatives:

DC04-11CGKWA and DC04-11GWA (Kingbright) offer the highest inventory availability (770 and 2200 units respectively) with active product status and full ROHS3 compliance. Both maintain the 16-DIP package and common cathode configuration. DC04-11GWA provides the largest stock position and matches the original forward voltage specification at 2.2V.

HDSP-G03G (Broadcom Limited) is an active product with ROHS3 compliance and matches the original 0.40" digit height and 16-DIP package. This part operates at a lower test current (10mA versus 20mA), reducing power dissipation to 65mW.

LDD-C402NI (Lumex Opto/Components Inc.) maintains 0.40" digit height, common cathode configuration, and 16-DIP packaging with ROHS3 compliance. Test current is 10mA with 2.2V forward voltage specification.

LTD-432GC (Lite-On Inc.) provides active product status with ROHS3 compliance, 0.40" digit height, and 20mA test current matching the original specification. Physical dimensions vary slightly in width (0.866" versus 0.795") and depth (0.319" versus 0.276").

Frequently Asked Questions (FAQ)

Q: Can I directly replace MSD4440C with any of these substitute parts?

A: Yes. All listed substitute parts share the same 16-DIP package footprint, common cathode pin configuration, 2-character 7-segment display topology, and green color output. Forward voltage and test current specifications fall within compatible operating ranges (2.05V to 2.2V; 10mA to 20mA).

Q: What is the difference between 10mA and 20mA test current specifications?

A: Test current defines the LED segment brightness measurement condition. Parts specified at 10mA (HDSP-G03G, LDD-C402NI) operate at lower power dissipation but may require circuit design adjustment if the original design assumes 20mA operation. Parts at 20mA (DC04-11CGKWA, DC04-11GWA, LTD-432GC) maintain closer electrical compatibility with the MSD4440C.

Q: Are there physical dimension differences I should consider?

A: Most substitutes maintain the 0.630" height and 0.795" width of the original. LTD-432GC has slightly larger dimensions (0.866" width, 0.319" depth). Verify PCB layout clearances if space is constrained. All parts fit the 16-DIP (0.500", 12.70mm) pitch standard.

Q: What does ROHS3 compliance mean for my application?

A: ROHS3 compliance certifies that the component meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. All active substitute parts carry this certification, ensuring regulatory compliance for new designs and production.

Q: Which substitute offers the best inventory availability?

A: DC04-11GWA (Kingbright) provides the largest stock position at 2200 units. DC04-11CGKWA (Kingbright) offers 770 units, and HDSP-G03G (Broadcom) provides 828 units. All three represent strong availability for immediate procurement.

Q: How do wavelength differences (565nm to 574nm) affect visual appearance?

A: All listed parts produce green output within the standard green LED wavelength range. Wavelength variations of 565nm to 574nm are imperceptible to human vision and do not affect functional compatibility or display readability in typical applications.
