Key Parameters

Substitute Part Grouping Explanation

Substitution of the HDSP-303E is determined by strict adherence to the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Display Type: 7-Segment configuration
• Number of Characters: Single character (1)
• Common Pin Configuration: Common Cathode
• Color: Red
• Package / Case: 10-DIP (0.300", 7.62mm)
• Current - Test: 20mA

Allowable Variation Parameters:

• Digit/Alpha Size: ±0.01" tolerance (0.39" to 0.41")
• Voltage - Forward (Vf): 1.9V to 2.0V range
• Millicandela Rating: Variation acceptable within brightness application requirements
• Wavelength - Peak: 627nm to 635nm range (red spectrum)
• Power Dissipation (Max): Up to 105mW
• Physical Dimensions: Minor variations acceptable within DIP package constraints

The SC39-11EWA manufactured by Kingbright meets all critical substitution parameters and falls within allowable variation ranges for electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the HDSP-303E and SC39-11EWA are Active product status components with ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings. Both components carry identical regulatory classifications: ECCN EAR99 and HTSUS 8541.41.0000.

The SC39-11EWA substitute part maintains full electrical and mechanical compatibility within the specified parameter ranges. The 10-DIP package footprint is identical, ensuring direct PCB layout compatibility. Both components support 20mA test current operation and common cathode configuration, enabling direct functional substitution in circuit designs.

The SC39-11EWA exhibits higher brightness (4.1mcd versus 1.8mcd) and lower maximum power dissipation (75mW versus 105mW), characteristics that may provide operational advantages in specific application contexts while maintaining electrical interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SC39-11EWA directly replace the HDSP-303E in existing circuit designs?

A: Yes. Both components share identical 10-DIP package configuration, common cathode pin arrangement, 20mA test current specification, and red color wavelength compatibility. The electrical interface is directly compatible.

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

A: The SC39-11EWA operates at 2.0V forward voltage compared to the HDSP-303E at 1.9V. The SC39-11EWA provides higher brightness (4.1mcd versus 1.8mcd) and lower maximum power dissipation (75mW versus 105mW). Physical dimensions vary slightly: SC39-11EWA is 0.512" H x 0.394" W versus HDSP-303E at 0.504" H x 0.382" W. Wavelength differs marginally: SC39-11EWA at 627nm versus HDSP-303E at 635nm.

Q: Are there any package or footprint considerations for substitution?

A: Both components use 10-DIP (0.300", 7.62mm) package configuration with identical pin spacing. PCB footprints are directly compatible. Minor physical dimension variations (approximately 0.008" in height and width) do not affect standard DIP socket or through-hole mounting applications.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the HDSP-303E and SC39-11EWA are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications. Both maintain MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: What should be considered when selecting between these two parts?

A: Selection should be based on application-specific brightness requirements and forward voltage operating parameters. The SC39-11EWA's higher brightness output (4.1mcd) suits applications requiring enhanced visibility. The 0.1V forward voltage difference (1.9V versus 2.0V) may impact current-limiting resistor calculations in the circuit design.
