MST6410C Equivalent & Substitute Parts

Part Overview

The MST6410C is a 3-character, 0.56" green 7-segment LED display module manufactured by onsemi in a 28-DIP package configuration. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The display operates at 2.1V forward voltage with 20mA test current and delivers 2.2mcd brightness output at a 570nm peak wavelength.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MST6410C is determined by strict alignment across the following parameters:

• Number of Characters: Must be 3
• Digit/Alpha Size: Must be 0.56" (14.22mm)
• Display Type: Must be 7-Segment
• Common Pin Configuration: Must be Common Anode
• Color: Must be Green
• Package / Case: Must be 28-DIP (0.600", 15.24mm)

Acceptable variations within substitute parts include forward voltage (Vf) within ±0.1V tolerance, test current within ±10mA, brightness (millicandela rating) variations, and wavelength peak shifts within the green spectrum range (565nm–574nm). Physical dimensions may vary slightly within manufacturing tolerances. All substitute parts must maintain the same functional pinout and electrical interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—BA56-11CGKWA, BA56-11GWA, and LDT-A512RI—are active products with current manufacturing status and full RoHS3 compliance. This ensures long-term availability and regulatory alignment for new designs and production runs.

BA56-11CGKWA (Kingbright) maintains identical electrical specifications to the MST6410C (2.1V, 20mA) with enhanced brightness output (35mcd vs. 2.2mcd). This part is suitable for applications requiring higher luminous intensity while preserving the original electrical interface.

BA56-11GWA (Kingbright) operates at 2.2V forward voltage with 20mA test current and delivers 8.6mcd brightness. The slight voltage increase (0.1V) is within acceptable tolerance for most circuit designs. This part is available in tube packaging.

LDT-A512RI (Lumex Opto/Components Inc.) operates at 2.2V with reduced test current (10mA vs. 20mA), resulting in lower power dissipation. This configuration is advantageous for power-constrained applications. The part is supplied in bulk packaging.

Selection should be based on circuit voltage tolerance, brightness requirements, and packaging preferences. All three parts maintain identical pinout and mechanical compatibility with the MST6410C footprint.

Frequently Asked Questions (FAQ)

Q: Can BA56-11CGKWA, BA56-11GWA, and LDT-A512RI be used interchangeably with MST6410C?

A: Yes, all three parts are direct substitutes. They share identical character count (3), digit size (0.56"), display type (7-segment), common anode configuration, green color, and 28-DIP package. Electrical parameters fall within acceptable tolerance ranges for standard circuit designs.

Q: What is the difference between the three substitute parts?

A: BA56-11CGKWA and BA56-11GWA are both Kingbright products with 20mA test current. BA56-11CGKWA delivers 35mcd brightness at 2.1V, while BA56-11GWA delivers 8.6mcd at 2.2V. LDT-A512RI (Lumex) operates at 2.2V with 10mA test current and 3.9mcd brightness. Choose based on brightness requirements and power budget.

Q: Will the 0.1V voltage difference between MST6410C (2.1V) and BA56-11GWA or LDT-A512RI (2.2V) affect circuit operation?

A: The 0.1V difference is within standard tolerance for LED display circuits. Most designs accommodate forward voltage variations of ±0.2V without circuit modification. Verify your specific current-limiting resistor design if operating near minimum supply voltage margins.

Q: Are all substitute parts RoHS compliant?

A: Yes. BA56-11CGKWA, BA56-11GWA, and LDT-A512RI are all ROHS3 compliant. The MST6410C RoHS status is not specified due to its obsolete classification.

Q: What packaging options are available?

A: BA56-11CGKWA is supplied in standard packaging. BA56-11GWA is available in tube packaging. LDT-A512RI is supplied in bulk packaging. All maintain the same 28-DIP footprint.

Q: Which substitute part should I select for a new design?

A: For new designs, any of the three active products are acceptable. BA56-11CGKWA is recommended if higher brightness is required. BA56-11GWA offers balanced performance with tube packaging convenience. LDT-A512RI is optimal for low-power applications due to its 10mA test current specification.
