Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC08-11CGKWA is determined by the following critical parameters:

Mechanical Compatibility:

• Identical physical dimensions: 1.091" H x 0.787" W x 0.331" D
• Identical digit size: 0.80" (20.32mm)
• Identical package type: 16-DIP (0.600", 15.24mm) with 13 leads

Functional Compatibility:

• Display type: 7-Segment
• Number of characters: 1
• Common pin configuration: Common Cathode
• Color: Green

Regulatory Compliance:

• RoHS3 Compliant status
• Moisture Sensitivity Level 1 (Unlimited)

The LDS-C812RI from Lumex Opto/Components Inc. meets all mechanical and functional compatibility criteria, allowing it to function as a direct substitute in applications where the SC08-11CGKWA is specified.

Parameter Comparison

Engineering Selection Recommendations

SC08-11CGKWA Selection Criteria:

• Primary choice when higher brightness output is required (25mcd vs. 2.5mcd)
• Applications requiring higher forward voltage tolerance (2.1V typical)
• Designs operating at 20mA test current specification
• Kingbright sourcing preference or existing supply chain integration

LDS-C812RI Selection Criteria:

• Applications where lower power consumption is prioritized (10mA test current)
• Designs with lower brightness requirements
• Lower forward voltage operation (2.0V typical)
• Lumex Opto/Components Inc. sourcing preference or inventory availability
• Higher maximum power dissipation tolerance (120mW)

Both parts maintain active product status and full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1), ensuring long-term availability and regulatory conformance for production designs.

Frequently Asked Questions (FAQ)

Q: Can the LDS-C812RI directly replace the SC08-11CGKWA in existing PCB designs?

A: Yes. Both parts share identical mechanical dimensions (1.091" H x 0.787" W x 0.331" D), digit size (0.80"), package type (16-DIP with 13 leads), display configuration (7-segment, single character, common cathode), and color (green). Pin-to-pin compatibility is maintained.

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

A: The SC08-11CGKWA operates at 2.1V forward voltage with 20mA test current and 25mcd brightness. The LDS-C812RI operates at 2.0V forward voltage with 10mA test current and 2.5mcd brightness. The SC08-11CGKWA provides approximately 10 times higher brightness output.

Q: Which part should be selected for brightness-critical applications?

A: The SC08-11CGKWA is specified for applications requiring higher luminous intensity (25mcd). The LDS-C812RI is suitable for applications where lower brightness is acceptable or preferred.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SC08-11CGKWA and LDS-C812RI are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), meeting current regulatory requirements for electronic component manufacturing and assembly.

Q: What is the wavelength difference between these displays?

A: The SC08-11CGKWA has a peak wavelength of 574nm, while the LDS-C812RI has a peak wavelength of 565nm. Both are within the green spectrum range, with the SC08-11CGKWA shifted slightly toward yellow-green.

Q: Can circuit design remain unchanged when substituting between these parts?

A: Circuit design modifications may be required due to differences in forward voltage (2.1V vs. 2.0V), test current (20mA vs. 10mA), and brightness output (25mcd vs. 2.5mcd). Current-limiting resistor values and power supply considerations should be reviewed for the selected part.
