SC56-11CGKWA Equivalent & Substitute Parts

Part Overview

The SC56-11CGKWA is a 0.56-inch single-character green 7-segment LED display module manufactured by Kingbright. This component is classified as a Display Module for LED Character and Numeric applications, featuring a common cathode configuration housed in a 10-DIP package. The part maintains Active product status and is RoHS3 compliant.

Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameters of the 7-segment display category. Alternatives become necessary when primary inventory is unavailable or when application-specific parameter tolerances permit selection from qualified equivalent components.

Engineering Selection Recommendations

Both the SC56-11CGKWA and LDS-C512RI maintain Active product status and full compliance with RoHS3 and REACH regulations, qualifying them for equivalent use in applications requiring green 7-segment display modules in 10-DIP packaging.

SC56-11CGKWA Selection Basis:

Higher luminous intensity (35mcd) suitable for applications requiring greater display brightness
Test current specification of 20mA aligns with standard LED display driver circuits
Lower maximum power dissipation (75mW) for thermal-constrained applications

LDS-C512RI Selection Basis:

Lower test current requirement (10mA) reduces power consumption in battery-operated or low-power applications
Mechanical dimensions (19.00mm × 12.60mm) provide minimal variation from primary part
Peak wavelength of 565nm maintains green spectrum consistency
Higher maximum power dissipation rating (105mW) accommodates extended operational margins

Selection between these parts depends on circuit current requirements, brightness specifications, and thermal design constraints. Both components are electrically and mechanically compatible within the 10-DIP common cathode 7-segment display category.

Frequently Asked Questions (FAQ)

Q: Can the LDS-C512RI directly replace the SC56-11CGKWA in existing PCB designs?

A: Yes. Both components share identical 10-DIP package dimensions (0.600", 15.24mm) and common cathode pin configuration. Mechanical and electrical compatibility is confirmed for direct substitution on PCBs designed for 0.56-inch green 7-segment displays.

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

A: The SC56-11CGKWA operates at 2.1V typical forward voltage with 20mA test current and 35mcd brightness. The LDS-C512RI operates at 2.2V typical forward voltage with 10mA test current and 3.5mcd brightness. Circuit design must account for these current and voltage specifications when selecting between parts.

Q: Are both parts suitable for high-brightness applications?

A: The SC56-11CGKWA, with 35mcd rating, is specified for applications requiring higher luminous intensity. The LDS-C512RI, rated at 3.5mcd, is suitable for standard-brightness applications or where lower power consumption is prioritized.

Q: Do dimensional tolerances affect PCB compatibility?

A: Dimensional variations between parts are minimal (0.05mm height difference, 0.10mm width difference). Both components fit standard 10-DIP footprints without modification. Verify PCB layout accommodates the specified 0.600-inch DIP spacing.

Q: What compliance certifications apply to both parts?

A: Both SC56-11CGKWA and LDS-C512RI are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component distribution and use.

Q: Which part should be selected for low-power applications?

A: The LDS-C512RI, with 10mA test current specification, is appropriate for power-constrained designs. The SC56-11CGKWA, specified at 20mA, is suitable for standard-power applications where brightness is not limited by current availability.
