SC36-11SRWA Equivalent & Substitute Parts

Part Overview

The SC36-11SRWA is a 0.36-inch single-character red 7-segment LED display module manufactured by Kingbright in a 10-DIP package configuration. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The display operates as a common cathode device with a typical forward voltage of 1.85V and test current of 20mA, suitable for numeric and alphanumeric display applications in industrial and consumer electronics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC36-11SRWA is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Display Type: 7-Segment
• Character Count: 1
• Digit/Alpha Size: 0.36" (9.14mm)
• Common Pin Configuration: Common Cathode
• Color: Red
• Package Type: 10-DIP (0.200", 5.08mm)
• Physical Dimensions: 0.551" H x 0.295" W x 0.335" D (14.00mm x 7.50mm x 8.50mm)

Allowable Parameter Variations: Substitute parts may vary in forward voltage (Vf), test current, millicandela rating, wavelength peak, and power dissipation within the constraints of common cathode 7-segment red LED display technology. These variations reflect different LED chip specifications and manufacturing processes while maintaining functional compatibility in standard display applications.

Two substitute parts meet these criteria: SC36-11SURKWA (Kingbright, Active status) and LDS-C324RI (Lumex Opto/Components Inc., Active status).

Parameter Comparison

Engineering Selection Recommendations

SC36-11SURKWA (Kingbright) is the manufacturer-recommended substitute. This part maintains the same Kingbright product line (base product number SC36-11) with active product status. The forward voltage increases from 1.85V to 1.95V, and brightness increases to 28mcd compared to the original 10mcd. Maximum power dissipation remains at 75mW. This substitute is suitable for applications where the increased brightness and slightly higher forward voltage are compatible with existing circuit designs.

LDS-C324RI (Lumex Opto/Components Inc.) is a functionally similar alternative from a different manufacturer. This part operates at 2V forward voltage with reduced test current of 10mA compared to the original 20mA specification. Brightness is significantly lower at 3.5mcd. Maximum power dissipation increases to 105mW. This substitute is applicable in designs where lower current consumption and reduced brightness are acceptable trade-offs.

Both substitutes maintain full compliance with ROHS3, REACH, and moisture sensitivity requirements. Selection between these options depends on circuit voltage tolerance, brightness requirements, and current budget constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can SC36-11SURKWA be used as a direct replacement for SC36-11SRWA?

A: SC36-11SURKWA is the manufacturer-recommended substitute and shares identical mechanical and electrical package specifications. The forward voltage difference of 0.1V (1.95V vs. 1.85V) and increased brightness (28mcd vs. 10mcd) are within the allowable parameter variations for common cathode 7-segment red LED displays. Circuit designs must accommodate the higher forward voltage and brightness characteristics.

Q: What are the key differences between SC36-11SURKWA and LDS-C324RI?

A: Both parts maintain identical physical dimensions, package type, and common cathode configuration. SC36-11SURKWA operates at 1.95V with 20mA test current and 28mcd brightness. LDS-C324RI operates at 2V with 10mA test current and 3.5mcd brightness. The Lumex part consumes less current but provides significantly lower brightness and higher maximum power dissipation (105mW vs. 75mW).

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 10-DIP (0.200", 5.08mm) package with identical physical dimensions of 0.551" H x 0.295" W x 0.335" D. Pin-to-pin compatibility is maintained across all three parts for common cathode 7-segment display applications.

Q: Which substitute should be selected for new designs?

A: SC36-11SURKWA is the preferred choice for new designs due to its active product status, manufacturer recommendation, and higher brightness rating. LDS-C324RI is suitable only when lower current consumption is a critical design requirement and reduced brightness is acceptable.

Q: Do all parts meet environmental compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry moisture sensitivity level 1 (unlimited). Compliance certifications are identical across all parts.

Q: What is the impact of wavelength differences (660nm, 645nm, 635nm) on visual appearance?

A: All three parts emit red light within the standard red LED spectrum. The wavelength variations reflect different LED chip technologies but produce visually similar red color output suitable for standard display applications.
