MSQC6412C Equivalent & Substitute Parts

Part Overview

The MSQC6412C is a 4-character 7-segment LED display module manufactured by onsemi, featuring a 0.56" digit size with common anode configuration and green color output. This display module is designed for numeric and alphanumeric applications requiring compact form factor and standard LED brightness characteristics. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design support, maintenance, and legacy system replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSQC6412C is determined by strict equivalence across the following critical parameters:

• Display Configuration: 4-character, 7-segment format with common anode connection
• Electrical Characteristics: Forward voltage of 2.1V and test current of 20mA
• Optical Properties: Green color output with 2.4mcd brightness rating
• Physical Compatibility: 0.56" digit size for visual consistency in display applications
• Mechanical Dimensions: Overall form factor suitable for PCB integration

The LTC-5623G from Lite-On Inc. meets these substitution criteria while maintaining functional and electrical equivalence to the MSQC6412C.

Parameter Comparison

Engineering Selection Recommendations

The LTC-5623G is a direct functional equivalent for the obsolete MSQC6412C. Selection of the LTC-5623G is supported by:

• Product Status: The LTC-5623G maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete MSQC6412C.
• Electrical Equivalence: Identical forward voltage (2.1V), test current (20mA), and brightness rating (2.4mcd) ensure drop-in compatibility in existing circuit designs.
• Compliance: The LTC-5623G is RoHS3 compliant, meeting current environmental and regulatory standards.
• Packaging Specification: The 12-DIP package provides standard through-hole mounting compatible with legacy PCB designs originally specified for the MSQC6412C.

Frequently Asked Questions (FAQ)

Q: Can the LTC-5623G replace the MSQC6412C in existing designs?

A: Yes. The LTC-5623G provides electrical and functional equivalence across all critical parameters: 4-character 7-segment display, common anode configuration, 2.1V forward voltage, 20mA test current, and 2.4mcd brightness. The 12-DIP package is compatible with standard through-hole PCB layouts.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (onsemi vs. Lite-On Inc.), product status (obsolete vs. active), and maximum power dissipation (70mW vs. 75mW). The LTC-5623G has a slightly higher overall height (0.748" vs. 0.673") and includes specified packaging (12-DIP). Wavelength peak differs slightly (565nm vs. 570nm), both within the green spectrum range.

Q: Are there packaging considerations for substitution?

A: The MSQC6412C packaging is not specified in available documentation. The LTC-5623G is supplied in 12-DIP (0.600", 15.24mm) packaging, which is standard for through-hole LED display modules. Verify PCB footprint compatibility with your original design specifications.

Q: Does the wavelength difference affect display appearance?

A: Both parts emit green light within standard LED wavelength ranges (565nm and 570nm). The visual difference is negligible in typical applications. Both maintain the same 2.4mcd brightness rating.

Q: What is the inventory status for these parts?

A: The MSQC6412C is obsolete with 1036 units available as new original stock. The LTC-5623G is in active production with 1962 units available as new original stock, providing better long-term availability.
