SC08-12CGKWA Equivalent & Substitute Parts

Part Overview

The SC08-12CGKWA is a single-character 7-segment LED display module manufactured by Kingbright. This green display operates with a common cathode configuration and is housed in a 16-DIP package with 13 leads. The component is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when alternative manufacturers offer functionally equivalent display modules that maintain compatibility with the same package footprint, pin configuration, and primary electrical operating characteristics. The SC08-12CGKWA has been identified as having one equivalent substitute from Lumex Opto/Components Inc.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC08-12CGKWA is determined by strict adherence to the following critical parameters:

Package and Mechanical Compatibility:

• Identical 16-DIP package footprint (0.600", 15.24mm)
• Identical 13-lead configuration
• Identical physical dimensions: 1.091" H x 0.787" W x 0.331" D

Electrical and Functional Compatibility:

• Single-character 7-segment display type
• Common cathode configuration
• Green color emission
• Forward voltage within acceptable operating range (2.0V to 2.1V)
• Test current specifications (10mA to 20mA)

Regulatory and Compliance Compatibility:

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

The LDS-C812RI from Lumex Opto/Components Inc. meets all substitution criteria for the SC08-12CGKWA based on these parameters.

Engineering Selection Recommendations

Primary Selection (SC08-12CGKWA): The SC08-12CGKWA remains the primary component choice when the specified electrical characteristics are required. This part is actively manufactured by Kingbright, maintains full RoHS3 compliance, and carries unlimited moisture sensitivity rating. The component is suitable for applications requiring the specified forward voltage (2.1V), test current (20mA), and brightness level (25mcd).

Substitute Selection (LDS-C812RI): The LDS-C812RI from Lumex Opto/Components Inc. is a valid substitute when inventory constraints or supply chain considerations necessitate an alternative source. This part maintains identical package compatibility, pin configuration, and physical dimensions. Both components are active products with equivalent regulatory compliance (RoHS3, MSL 1, REACH unaffected).

Electrical Differences: The LDS-C812RI operates at a lower forward voltage (2.0V versus 2.1V) and lower test current (10mA versus 20mA). The substitute exhibits lower brightness (2.5mcd versus 25mcd) and a different peak wavelength (565nm versus 574nm). These differences must be evaluated against specific application requirements before substitution.

Compliance Basis: Both components satisfy identical regulatory requirements: RoHS3 compliance, MSL 1 rating, and REACH unaffected status. Selection between these parts should be based on electrical performance requirements and supply availability rather than compliance considerations.

Frequently Asked Questions (FAQ)

Q: Can the LDS-C812RI be used as a direct replacement for the SC08-12CGKWA in existing PCB designs?

A: The LDS-C812RI is mechanically compatible with the SC08-12CGKWA due to identical package footprint (16-DIP), pin count (13 leads), and physical dimensions. However, electrical performance differs. The substitute operates at lower forward voltage (2.0V vs. 2.1V), lower test current (10mA vs. 20mA), and significantly lower brightness (2.5mcd vs. 25mcd). PCB designs must accommodate these electrical differences through circuit modifications.

Q: What are the key compatibility criteria for 7-segment display substitution?

A: Substitution eligibility requires: identical package type and pin configuration, matching common pin configuration (common cathode or common anode), identical character size and display type, compatible forward voltage range, and equivalent regulatory compliance status. The SC08-12CGKWA and LDS-C812RI meet these criteria.

Q: How do the brightness differences between these parts affect application suitability?

A: The SC08-12CGKWA provides 25mcd brightness, while the LDS-C812RI provides 2.5mcd brightness. This 10-fold difference is significant for visibility in various lighting conditions. Applications requiring high-brightness display output should retain the SC08-12CGKWA. Applications with lower brightness requirements or controlled lighting environments may accommodate the LDS-C812RI.

Q: Are both parts suitable for high-temperature or moisture-sensitive applications?

A: Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Both maintain RoHS3 compliance. Specific temperature operating ranges are not provided in the available parameters. Consult detailed datasheets for thermal operating specifications.

Q: What is the significance of the wavelength difference (574nm vs. 565nm)?

A: Both wavelengths fall within the green spectrum. The SC08-12CGKWA emits at 574nm (yellow-green), while the LDS-C812RI emits at 565nm (pure green). Visual color perception differences may be apparent in side-by-side comparison. Application requirements for specific color matching should be evaluated before substitution.

Q: Can circuit design accommodate the lower current requirement of the LDS-C812RI?

A: The LDS-C812RI operates at 10mA test current compared to the SC08-12CGKWA at 20mA. This lower current requirement may reduce power dissipation in the application circuit. However, circuit modifications to current-limiting resistors and driver circuitry are necessary to ensure proper operation at the lower current specification.
