SC08-11SRWA Equivalent & Substitute Parts

Part Overview

The SC08-11SRWA is a 7-segment LED display module manufactured by Kingbright, featuring a single 0.8-inch red character in common cathode configuration. This component is classified as obsolete, indicating discontinued production and limited availability in standard distribution channels. The SC08-11SRWA operates at 1.85V forward voltage with a 20mA test current and delivers 36mcd brightness output at a 660nm peak wavelength. Due to its obsolete status, identifying compatible substitute parts is essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC08-11SRWA is determined by strict alignment across the following critical parameters:

Physical and Functional Compatibility:

• Display type must be 7-Segment
• Number of characters must be 1
• Digit/Alpha size must be 0.80" (20.32mm)
• Color must be Red
• Common pin configuration must be Common Cathode
• Package must be 16-DIP (0.600", 15.24mm), 13 Leads

Electrical Operating Parameters:

• Forward voltage (Vf) tolerance: acceptable range within typical LED specifications
• Test current: 20mA
• Power dissipation maximum: 75mW

Compliance and Environmental:

• RoHS3 compliance required
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The SC08-11SURKWA meets all substitution criteria. While this part exhibits a higher forward voltage (1.95V versus 1.85V) and increased brightness output (61mcd versus 36mcd), these parameters remain within the functional envelope of the 16-DIP common cathode 7-segment display category and do not preclude direct substitution in circuit applications designed for the SC08-11SRWA.

Parameter Comparison

Engineering Selection Recommendations

The SC08-11SURKWA is the manufacturer-recommended substitute for the obsolete SC08-11SRWA. Both components share identical mechanical form factors, pinout configurations, and package specifications, enabling direct socket compatibility in existing PCB designs.

The SC08-11SURKWA maintains active product status, ensuring continued availability and supply chain reliability. Both parts carry ROHS3 compliance certification and unlimited moisture sensitivity rating (MSL 1), satisfying regulatory and environmental requirements for industrial and commercial applications.

The SC08-11SURKWA exhibits a 0.10V increase in forward voltage (1.95V versus 1.85V) and a 25mcd increase in brightness output (61mcd versus 36mcd). These electrical variations remain within the operational envelope of standard 7-segment display driver circuits and do not introduce incompatibility with existing control electronics or current-limiting resistor networks designed for the SC08-11SRWA.

Frequently Asked Questions (FAQ)

Q: Can the SC08-11SURKWA be used as a direct replacement for the SC08-11SRWA in existing designs?

A: Yes. Both components share identical package specifications (16-DIP, 13 leads), pinout configurations (common cathode), and physical dimensions (0.80" character size). The SC08-11SURKWA is electrically compatible with circuits designed for the SC08-11SRWA.

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

A: The SC08-11SURKWA operates at 1.95V forward voltage compared to 1.85V for the SC08-11SRWA, and delivers 61mcd brightness versus 36mcd. The SC08-11SURKWA is active product status while the SC08-11SRWA is obsolete. Peak wavelength differs slightly (645nm versus 660nm).

Q: Will the increased brightness of the SC08-11SURKWA affect circuit operation?

A: No. The increased brightness results from improved LED die efficiency and does not alter the electrical interface or current requirements. Both parts operate at 20mA test current and 75mW maximum power dissipation.

Q: Are there any compliance or certification differences?

A: No. Both the SC08-11SRWA and SC08-11SURKWA carry identical ROHS3 compliance certification and unlimited moisture sensitivity rating (MSL 1).

Q: Why is the SC08-11SRWA classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The SC08-11SURKWA represents the active replacement offering from Kingbright within the same product family.

Q: What packaging options are available for the SC08-11SURKWA?

A: The SC08-11SURKWA is supplied in tube packaging, suitable for automated assembly and manual component handling.
