MAN413C 7-Segment LED Display Equivalent & Substitute Parts

Part Overview

The MAN413C is a single-character red 7-segment LED display manufactured by onsemi, featuring a 0.39" digit height in a 10-DIP package configuration. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The display operates at 2.1V forward voltage with a 20mA test current and delivers 0.7mcd brightness output at a 697nm peak wavelength.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAN413C are qualified based on the following electrical and mechanical compatibility criteria:

Primary Compatibility Parameters:

• Display type: 7-Segment configuration
• Character count: Single character
• Common pin configuration: Common Cathode
• Color: Red
• Package type: 10-DIP (0.300", 7.62mm)
• Test current: 20mA
• Forward voltage range: 1.8V to 2.1V (acceptable operating margin)
• Digit height: 0.39" to 0.40" (within dimensional tolerance)

The identified substitute parts HDSP-303A and HDSP-303E, both manufactured by Broadcom Limited, meet these core compatibility requirements. Both maintain the same package footprint, pin configuration, and electrical operating parameters within acceptable engineering tolerances for direct circuit board substitution.

Engineering Selection Recommendations

HDSP-303E is the primary substitute for the MAN413C. This part maintains active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. The forward voltage of 1.9V is within acceptable operating tolerance of the original 2.1V specification, and the 20mA test current matches exactly. The higher millicandela rating (1.8mcd versus 0.7mcd) provides improved brightness performance in the same package footprint.

HDSP-303A serves as an alternative substitute when brightness reduction is acceptable for the application. This part also carries active product status and ROHS3 compliance. The 1.8V forward voltage and lower millicandela rating (0.45mcd) represent a more conservative electrical profile, suitable for applications with reduced brightness requirements or lower power budgets.

Both substitute parts are pin-compatible with the MAN413C in 10-DIP configuration and require no circuit modifications for direct replacement.

Frequently Asked Questions (FAQ)

Q: Can HDSP-303A and HDSP-303E be used interchangeably with MAN413C?

A: Both parts are electrically and mechanically compatible with MAN413C in 10-DIP common cathode configuration. The primary difference is brightness output: HDSP-303E delivers 1.8mcd while HDSP-303A delivers 0.45mcd. Selection depends on application brightness requirements.

Q: What is the impact of the forward voltage difference between MAN413C (2.1V) and the substitute parts (1.8V to 1.9V)?

A: The substitute parts operate at lower forward voltages, reducing power dissipation and heat generation. Circuit designs using current-limiting resistors will require recalculation to maintain the 20mA test current specification. The voltage difference is within normal LED operating tolerances.

Q: Are the physical dimensions compatible for PCB layout?

A: The substitute parts (HDSP-303A and HDSP-303E) have slightly smaller overall dimensions (0.504" H x 0.382" W versus 0.512" H x 0.390" W) but maintain identical 10-DIP package footprint and pin spacing. Direct PCB substitution is possible without layout modifications.

Q: What is the wavelength difference between MAN413C and the substitutes?

A: MAN413C operates at 697nm (standard red), HDSP-303A at 660nm (pure red), and HDSP-303E at 635nm (deep red). These wavelength variations represent different red LED technologies. Visual color appearance will differ slightly; selection should be based on application color requirements.

Q: Do the substitute parts have RoHS compliance?

A: Both HDSP-303A and HDSP-303E are ROHS3 compliant. The original MAN413C does not specify RoHS status. For applications requiring RoHS certification, the Broadcom substitutes are the appropriate choice.

Q: What is the MSL rating for these parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
