SC43-11GWA Equivalent & Substitute Parts

Part Overview

The SC43-11GWA is a green 7-segment LED display module manufactured by Kingbright, designed for single-character numeric and alphanumeric display applications. This common cathode display operates at 2.2V forward voltage with a 20mA test current and delivers 10mcd brightness at a 565nm peak wavelength. The component is housed in a 14-DIP package with 11 leads and measures 0.748" H × 0.496" W × 0.310" D (19.00mm × 12.60mm × 7.87mm).

The SC43-11GWA maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for 7-segment LED display modules in this form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SC43-11GWA are identified based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Display Type: 7-Segment
• Number of Characters: 1
• Common Pin Configuration: Common Cathode
• Color: Green
• Digit/Alpha Size: 0.43" (within tolerance)
• Package / Case: 14-DIP (0.300", 7.62mm), 11 Leads

Allowed Electrical Parameter Ranges:

• Voltage - Forward (Vf): 2.1V to 2.2V
• Current - Test: 10mA to 20mA
• Millicandela Rating: 4mcd to 10mcd
• Wavelength - Peak: 565nm to 566nm
• Power Dissipation (Max): 62.5mW to 105mW

Compliance Requirements:

Engineering Selection Recommendations

SC43-11GWA (Kingbright) - Primary Selection

The SC43-11GWA is the specified component and remains the primary choice for applications requiring the exact electrical and optical characteristics defined in the design specification. This part is Active, ROHS3 compliant, and maintains unlimited moisture sensitivity rating. Current inventory of 1034 units supports immediate procurement.

HDSP-4603 (Broadcom Limited) - Substitute Selection

The HDSP-4603 qualifies as a direct substitute when component availability or supply chain considerations necessitate an alternative source. This part maintains Active product status and ROHS3 compliance. The HDSP-4603 operates at a lower forward voltage (2.1V vs. 2.2V) and lower test current (10mA vs. 20mA), resulting in reduced power dissipation (105mW maximum vs. 62.5mW maximum). The brightness rating is lower (4mcd vs. 10mcd), and the wavelength peak is marginally shifted (566nm vs. 565nm). Physical dimensions are within tolerance for PCB mounting compatibility. Inventory availability of 1989 units supports procurement.

Selection Criteria:

• Use SC43-11GWA when the specified 10mcd brightness and 20mA operating current are required by the circuit design.
• Use HDSP-4603 when lower power dissipation and reduced brightness are acceptable within the application requirements, or when supply chain constraints limit SC43-11GWA availability.
• Both parts are suitable for applications requiring ROHS3 compliance and unlimited moisture sensitivity handling.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-4603 be used as a direct pin-for-pin replacement for the SC43-11GWA?

A: Yes. Both parts use the 14-DIP (0.300", 7.62mm) package with 11 leads and common cathode configuration. Pin assignments are compatible for direct substitution on PCB layouts designed for the SC43-11GWA.

Q: What are the key electrical differences between SC43-11GWA and HDSP-4603?

A: The SC43-11GWA operates at 2.2V forward voltage with 20mA test current and 10mcd brightness. The HDSP-4603 operates at 2.1V forward voltage with 10mA test current and 4mcd brightness. Both operate within the allowed parameter ranges for this product category.

Q: Will the lower brightness of the HDSP-4603 affect display visibility?

A: The HDSP-4603 delivers 4mcd compared to the SC43-11GWA's 10mcd. Visibility impact depends on ambient lighting conditions and viewing distance specified in the application design. Circuit designers must evaluate brightness requirements independently.

Q: Are both parts RoHS compliant?

A: Yes. Both the SC43-11GWA and HDSP-4603 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the wavelength difference between these parts?

A: The SC43-11GWA has a peak wavelength of 565nm, while the HDSP-4603 has a peak wavelength of 566nm. This 1nm difference is within the green LED spectrum and does not affect functional compatibility.

Q: Can I use HDSP-4603 in a high-brightness application originally designed for SC43-11GWA?

A: No. The HDSP-4603's 4mcd rating is lower than the SC43-11GWA's 10mcd rating. Applications requiring the higher brightness specification must use the SC43-11GWA.

Q: What are the physical dimension tolerances between these parts?

A: SC43-11GWA measures 0.748" H × 0.496" W × 0.310" D. HDSP-4603 measures 0.750" H × 0.500" W × 0.250" D. Differences are within tolerance for standard PCB mounting. The HDSP-4603 is 0.060" thinner, which may affect clearance in space-constrained applications.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. No compliance differences exist between the two parts.
