CC56-12SRWA Equivalent & Substitute Parts

Part Overview

The CC56-12SRWA is a 4-character red 7-segment LED display module manufactured by Kingbright, configured with common cathode architecture. This component is classified as obsolete and is no longer in active production. The display features 0.56-inch character height and operates at 1.8V forward voltage with 10mA test current, suitable for numeric and alphanumeric display applications in legacy electronic equipment.

Due to its obsolete status, sourcing replacement units from original inventory is limited. Identifying equivalent substitute parts ensures design continuity and maintains system functionality in applications requiring this display module category.

Substitute Part Grouping Explanation

Substitution of the CC56-12SRWA is determined by strict equivalence in the following critical parameters:

Mandatory Matching Parameters:

• Number of Characters: 4
• Display Type: 7-Segment
• Common Pin Configuration: Common Cathode
• Color: Red
• Character Height: 0.56" (14.20mm)
• Physical Dimensions: 0.748" H x 1.980" W x 0.329" D
• Package Type: 12-DIP (0.600", 15.24mm)

Allowable Variation Parameters:

• Voltage - Forward (Vf): Within compatible operating range for common cathode red LED displays
• Millicandela Rating: May vary based on LED technology improvements
• Wavelength - Peak: Acceptable variation within red spectrum for visual compatibility

The CC56-12SURKWA qualifies as a direct substitute based on identical mechanical form factor, pin configuration, character count, and display architecture. Both components share the same base product number (CC56-12) and are manufactured by Kingbright.

Parameter Comparison

Engineering Selection Recommendations

The CC56-12SURKWA is the manufacturer-recommended substitute for the obsolete CC56-12SRWA. Selection of this substitute is based on the following engineering criteria:

Mechanical Compatibility: Both components share identical physical dimensions, pin spacing, and 12-DIP package configuration, ensuring direct PCB footprint compatibility without layout modifications.

Electrical Compatibility: The CC56-12SURKWA operates at 1.85V forward voltage, a 0.05V increase from the original 1.8V specification. This variation remains within acceptable tolerances for common cathode red LED display circuits and does not require circuit redesign.

Functional Equivalence: Both parts maintain identical character count (4), display type (7-segment), common cathode configuration, and test current (10mA), ensuring functional parity in display applications.

Product Status Advantage: The CC56-12SURKWA holds active product status with current manufacturing availability, addressing the supply constraint of the obsolete CC56-12SRWA. Current inventory of 792 units is available.

Compliance Status: The CC56-12SURKWA is RoHS3 compliant and EAR99 classified, meeting modern regulatory requirements for component procurement and export.

Frequently Asked Questions (FAQ)

Q: Can the CC56-12SURKWA be used as a direct replacement for CC56-12SRWA without circuit modifications?

A: Yes. The CC56-12SURKWA is electrically and mechanically compatible with the CC56-12SRWA. The 0.05V increase in forward voltage (1.85V vs. 1.8V) does not require circuit redesign for standard common cathode LED display applications.

Q: What is the difference in brightness between these two parts?

A: The CC56-12SURKWA provides 72mcd brightness compared to 34mcd for the CC56-12SRWA. This represents improved LED technology in the substitute part, resulting in higher luminous intensity while maintaining identical electrical operating parameters.

Q: Are the wavelength differences between 655nm and 645nm visually significant?

A: Both wavelengths fall within the red spectrum range. The 10nm difference (655nm vs. 645nm) represents a shift toward orange-red but remains within acceptable color tolerance for red LED display applications. Visual appearance will be consistent in typical display applications.

Q: Is the CC56-12SURKWA available in the same packaging as the original part?

A: Yes. Both components use 12-DIP (0.600", 15.24mm) package configuration with identical physical dimensions of 0.748" H x 1.980" W x 0.329" D. The substitute is available in bulk packaging.

Q: What is the inventory status for the CC56-12SURKWA?

A: The CC56-12SURKWA has 792 units in current stock as a new original component. The original CC56-12SRWA has 1118 units remaining in obsolete inventory.

Q: Does the CC56-12SURKWA meet current regulatory standards?

A: Yes. The CC56-12SURKWA is RoHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes, meeting current regulatory requirements for electronic component procurement.
