Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HDSP-8603 is determined by strict adherence to the following criteria:

Critical Parameters (Must Match):

• Display Type: 7-Segment
• Number of Characters: 1
• Common Pin Configuration: Common Cathode
• Color: Green
• Digit Size: 0.80" (20.32mm)
• Package Type: 18-DIP (0.600", 15.24mm)

Allowed Variation Parameters:

• Voltage - Forward (Vf): Within typical operating range for green LEDs (2.1V to 2.2V)
• Current - Test: May vary based on brightness and efficiency characteristics
• Millicandela Rating: May vary based on LED efficiency
• Wavelength - Peak: Within green spectrum range (565nm to 566nm)
• Power Dissipation: Dependent on current and voltage characteristics

The SC08-11GWA from Kingbright meets all critical parameters and operates within allowed electrical variation ranges, qualifying it as a direct substitute for the HDSP-8603.

Parameter Comparison

Engineering Selection Recommendations

Both the HDSP-8603 and SC08-11GWA are Active product status components with ROHS3 compliance and MSL Level 1 rating. The SC08-11GWA demonstrates higher brightness output (13mcd versus 1.5mcd) and lower maximum power dissipation (62.5mW versus 105mW) while maintaining identical package geometry and pin configuration. Both components are REACH Unaffected and classified under EAR99 export control. Selection between these parts should be based on application-specific brightness requirements and circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can SC08-11GWA replace HDSP-8603 in existing circuit designs?

A: Yes. Both components share identical package type (18-DIP), pin configuration (Common Cathode), display format (7-Segment, single character), color (Green), and digit size (0.80"). Physical dimensions are equivalent within manufacturing tolerance. Pin-to-pin compatibility is maintained.

Q: What are the electrical differences between these parts?

A: The SC08-11GWA operates at 2.2V forward voltage versus 2.1V for the HDSP-8603, and the test current is specified at 20mA versus 10mA. The SC08-11GWA exhibits higher brightness (13mcd) and lower maximum power dissipation (62.5mW). These differences reflect different LED die efficiency characteristics within the same package.

Q: Are there compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, MSL Level 1, and classified as EAR99 for export control purposes.

Q: What is the wavelength difference significance?

A: Both parts emit within the green spectrum range (565nm to 566nm). This 1nm difference is within normal manufacturing variation for green LEDs and is not functionally significant for display applications.

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

A: Selection depends on circuit design requirements. The SC08-11GWA provides significantly higher brightness output (13mcd) compared to the HDSP-8603 (1.5mcd). Circuit current limiting and power budget must be evaluated for the specific application.
