HDSP-333E 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The HDSP-333E is a single-character red 7-segment LED display manufactured by Broadcom Limited, designed for numeric and alphanumeric display applications. This component features a common cathode configuration with a 0.30-inch character height and operates at 2.05V forward voltage with 20mA test current. The display is currently in active production status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, manufacturing discontinuation, or application-specific sourcing needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HDSP-333E is determined by strict alignment of the following electrical and mechanical parameters:

• Display Type: 7-Segment configuration
• Number of Characters: Single character
• Character Height: 0.30" (7.62mm)
• Common Pin Configuration: Common Cathode
• Color: Red
• Voltage - Forward (Vf): Within acceptable operating range (2.0V to 2.05V)
• Current - Test: 20mA
• Package / Case: 14-DIP (0.300", 7.62mm)
• RoHS Compliance: ROHS3 Compliant

The SC03-12EWA from Kingbright meets all substitution criteria, maintaining electrical compatibility and mechanical interchangeability with the HDSP-333E.

Parameter Comparison

Engineering Selection Recommendations

Both the HDSP-333E and SC03-12EWA are active production components with identical RoHS3 compliance and REACH unaffected status. The SC03-12EWA operates at 2V forward voltage compared to the HDSP-333E's 2.05V, representing a 0.05V difference within typical LED operating tolerances. Physical dimensions are equivalent within manufacturing tolerances. Both components maintain MSL Level 1 (Unlimited) moisture sensitivity classification. Selection between these parts should be based on availability, packaging format (Bulk versus Tube), and application-specific sourcing requirements.

Frequently Asked Questions (FAQ)

Q: Can SC03-12EWA replace HDSP-333E in existing circuit designs?

A: Yes. Both components share identical display type, character height, common cathode configuration, test current, and DIP package specifications. The 0.05V forward voltage difference falls within standard LED operating parameters.

Q: Are there mechanical compatibility concerns?

A: No. Physical dimensions differ by less than 0.06mm in height and width, which is within standard manufacturing tolerances for 14-DIP packages. Both components use identical lead spacing and pin configuration.

Q: What is the difference in packaging between these parts?

A: HDSP-333E is supplied in Bulk packaging, while SC03-12EWA is supplied in Tube packaging. This affects handling and storage but does not impact electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both HDSP-333E and SC03-12EWA are ROHS3 compliant, REACH unaffected, and classified as MSL Level 1 (Unlimited).

Q: Are there brightness differences between these displays?

A: The SC03-12EWA has a higher millicandela rating (8.1mcd) compared to the HDSP-333E (1.8mcd). This indicates greater brightness output and should be considered if the application has specific luminous intensity requirements.
