SC52-11EWA 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The SC52-11EWA is a single-character red 7-segment LED display module manufactured by Kingbright. This common cathode display operates at 2V forward voltage with a 20mA test current and features a 0.52" digit height. The component is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when addressing supply chain constraints, design optimization for power consumption, or mechanical fit requirements in specific applications. The following equivalent components maintain functional compatibility through matching package type (10-DIP), display configuration (7-segment, single character, common cathode), and color specification (red).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC52-11EWA is determined by the following mandatory parameters:

Fixed Requirements (Non-Negotiable):

• Display Type: 7-Segment, single character configuration
• Common Pin: Common Cathode topology
• Color: Red wavelength range
• Package: 10-DIP (0.600", 15.24mm) footprint
• Compliance: RoHS3 and REACH status alignment

Variable Parameters (Allowable Ranges):

• Digit Height: 0.51" to 0.56" (13.00mm to 14.22mm)
• Forward Voltage: 1.7V to 2.1V
• Test Current: 1mA to 20mA
• Wavelength Peak: 627nm to 650nm
• Power Dissipation: 52mW to 185mW

All three substitute parts (HDSP-5503, HDSP-5553, TDSR1360) satisfy the fixed requirements and operate within the allowable variable parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

HDSP-5503 (Broadcom Limited) is suitable for applications requiring brightness levels comparable to the SC52-11EWA. This substitute operates at 2.1V forward voltage with 20mA test current, maintaining similar power dissipation characteristics (105mW maximum). The 0.56" digit height represents a 7.7% increase in character size. All regulatory certifications (RoHS3, REACH Unaffected) align with the primary part.

HDSP-5553 (Broadcom Limited) is appropriate for power-constrained applications. This substitute operates at reduced current (5mA test) and lower forward voltage (1.7V), resulting in 52mW maximum power dissipation—31% lower than the SC52-11EWA. Brightness is correspondingly reduced (1.48mcd). The 0.56" digit height and full compliance status maintain mechanical and regulatory compatibility.

TDSR1360 (Vishay Semiconductor Opto Division) is suitable for ultra-low-power applications. This substitute operates at 1mA test current and 1.8V forward voltage, with 185mW maximum power dissipation specification. The 0.51" digit height provides closest dimensional match to the SC52-11EWA (0.2mm difference). All regulatory certifications are maintained.

All substitute parts maintain active product status and unlimited moisture sensitivity rating (MSL 1), ensuring long-term availability and storage compatibility with the primary component.

Frequently Asked Questions (FAQ)

Q: Can HDSP-5503 be used as a direct replacement for SC52-11EWA in existing PCB designs?

A: Yes. Both components use identical 10-DIP (0.600", 15.24mm) package footprints and common cathode configuration. The 0.56" digit height of HDSP-5503 versus 0.52" for SC52-11EWA represents a 7.7% size increase, which may affect visual appearance but does not impact electrical compatibility or PCB mounting.

Q: What is the primary advantage of HDSP-5553 over SC52-11EWA?

A: HDSP-5553 operates at significantly lower power consumption (52mW maximum versus 75mW) due to reduced test current (5mA versus 20mA) and lower forward voltage (1.7V versus 2V). This substitute is selected when power budget optimization is required. Brightness output is reduced proportionally (1.48mcd versus 6.4mcd).

Q: Is TDSR1360 compatible with the SC52-11EWA package footprint?

A: Yes. TDSR1360 uses the same 10-DIP (0.600", 15.24mm) package type. The physical dimensions are nearly identical (0.51" digit height versus 0.52"), making this substitute suitable for direct PCB replacement without layout modifications.

Q: Do all substitute parts meet the same compliance requirements as SC52-11EWA?

A: Yes. HDSP-5503, HDSP-5553, and TDSR1360 are all RoHS3 compliant with REACH Unaffected status. All components carry MSL 1 (Unlimited) moisture sensitivity rating, matching the primary part's environmental specifications.

Q: Which substitute part most closely matches the brightness of SC52-11EWA?

A: HDSP-5503 provides the closest brightness match at 2.8mcd compared to SC52-11EWA's 6.4mcd. TDSR1360 offers 3.6mcd, while HDSP-5553 provides the lowest brightness at 1.48mcd. Brightness selection depends on application visibility requirements.

Q: Can forward voltage differences between substitutes affect circuit design?

A: Forward voltage differences (1.7V to 2.1V range) require verification of series resistor values in the driving circuit. Applications using fixed current-limiting resistors may require recalculation to maintain proper LED current levels. Test current specifications (1mA to 20mA) should be cross-referenced with circuit design parameters.
