MSQC6410W Equivalent & Substitute Parts

Part Overview

The MSQC6410W 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 character display applications requiring 2.1V forward voltage and 20mA test current operation.

The MSQC6410W is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this display module.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSQC6410W is determined by the following critical parameters:

• Number of Characters: Must be 4-character configuration
• Digit/Alpha Size: Must be 0.56" (14.22mm) to maintain mechanical and optical compatibility
• Display Type: Must be 7-segment configuration
• Common Pin Configuration: Must be common anode
• Color: Must be green
• Voltage - Forward (Vf): Must be 2.1V typical
• Current - Test: Must be 20mA

The CA56-11CGKWA from Kingbright meets all critical substitution parameters. While minor variations exist in physical dimensions, millicandela rating, wavelength peak, and power dissipation, these differences do not preclude functional substitution when the core electrical and display characteristics align with the specified requirements.

Parameter Comparison

Engineering Selection Recommendations

The CA56-11CGKWA is a qualified substitute for the MSQC6410W based on matching electrical specifications and display characteristics. The substitute part is currently in active production status, ensuring ongoing availability and supply chain support.

The CA56-11CGKWA carries RoHS3 compliance certification, providing environmental and regulatory alignment for new designs and production continuity. Both parts maintain REACH Unaffected status and EAR99 export classification.

Physical dimension variations between the two parts are minor and localized to height and depth measurements. Width remains consistent at approximately 1.98". These dimensional differences require mechanical fit verification within the target application enclosure or PCB layout.

The CA56-11CGKWA exhibits higher luminous intensity (35mcd versus 2.4mcd), which may require adjustment to current-limiting resistor values if brightness consistency is critical to the application. Wavelength peak variation (574nm versus 570nm) is within acceptable green LED spectrum tolerance and will not produce perceptible color differences in typical viewing conditions.

Frequently Asked Questions (FAQ)

Q: Can the CA56-11CGKWA directly replace the MSQC6410W without circuit modifications?

A: The CA56-11CGKWA is electrically compatible with the MSQC6410W at the specified 2.1V forward voltage and 20mA test current. However, the higher millicandela rating (35mcd versus 2.4mcd) may require adjustment to current-limiting resistor values to maintain consistent brightness levels in the target application. Mechanical fit verification is required due to minor dimensional differences.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), millicandela rating (2.4mcd versus 35mcd), physical height (0.673" versus 0.748"), and compliance certifications (RoHS3 for the substitute). All critical electrical and display parameters remain identical.

Q: Are there any package or pinout differences?

A: The MSQC6410W uses a standard package configuration, while the CA56-11CGKWA is specified as 36-DIP (0.600", 15.24mm). Both maintain common anode 4-character 7-segment configuration. Pinout compatibility must be verified against the specific application schematic.

Q: Why is the CA56-11CGKWA brighter than the MSQC6410W?

A: The CA56-11CGKWA is rated at 35mcd compared to 2.4mcd for the MSQC6410W. This higher luminous intensity is a characteristic of the Kingbright design and may require resistor value adjustment to achieve equivalent brightness in the target application.

Q: Is the wavelength difference significant?

A: The wavelength peak difference (574nm versus 570nm) is within standard green LED spectrum variation and will not produce perceptible color differences in typical viewing conditions. Both wavelengths are classified as green and are suitable for applications requiring green numeric display output.
