MAN6181C 7-Segment LED Display Equivalent & Substitute Parts

Part Overview

The MAN6181C is a single-character, 0.56-inch red 7-segment LED display manufactured by onsemi in a 10-DIP package configuration. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The display operates at 2.1V forward voltage with a 20mA test current and is housed in a standard 10-DIP (0.600", 15.24mm) package with common cathode configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAN6181C are qualified based on the following electrical and mechanical parameters:

Primary Compatibility Criteria:

• Display type: 7-Segment LED (single character)
• Digit size: 0.56" (14.22mm)
• Color: Red
• Common pin configuration: Common Cathode
• Package type: 10-DIP (0.600", 15.24mm)

Secondary Electrical Parameters:

• Forward voltage (Vf): 2.1V nominal (acceptable range based on circuit design tolerance)
• Test current: 20mA nominal
• Wavelength range: 635nm to 697nm (red spectrum)

Two active substitute parts meet these criteria: HDSP-5503 (Broadcom Limited) and HDSP-H113 (Broadcom Limited). Both maintain identical mechanical compatibility and common cathode configuration. Electrical parameters vary within acceptable ranges for 7-segment display applications.

Engineering Selection Recommendations

HDSP-5503 Selection Criteria: The HDSP-5503 maintains electrical parity with the MAN6181C, operating at 2.1V forward voltage and 20mA test current. This part is recommended for direct replacement in existing circuit designs without modification. The HDSP-5503 is active production status and ROHS3 compliant, supporting long-term supply chain continuity. Higher millicandela rating (2.8mcd vs. 0.7mcd) provides improved brightness margin. Packaged in tube format.

HDSP-H113 Selection Criteria: The HDSP-H113 operates at reduced voltage (1.7V) and current (5mA), resulting in lower power dissipation (37mW). This part is suitable for applications where power efficiency is prioritized or where circuit design permits lower operating current. The HDSP-H113 offers the highest brightness rating (4.2mcd) among available substitutes. Active production status and ROHS3 compliance are confirmed. Packaged in bulk format.

Both substitute parts are manufactured by Broadcom Limited and carry active product status, ensuring availability and ongoing technical support. Selection between HDSP-5503 and HDSP-H113 depends on circuit design requirements regarding voltage, current, and brightness specifications.

Frequently Asked Questions (FAQ)

Q: Can HDSP-5503 be used as a direct replacement for MAN6181C without circuit modification? A: Yes. The HDSP-5503 maintains identical forward voltage (2.1V), test current (20mA), and package configuration (10-DIP common cathode). No circuit redesign is required for this substitution.

Q: What are the key differences between HDSP-5503 and HDSP-H113? A: The HDSP-H113 operates at lower voltage (1.7V vs. 2.1V) and current (5mA vs. 20mA), resulting in reduced power dissipation. The HDSP-H113 provides higher brightness (4.2mcd vs. 2.8mcd). Circuit design must accommodate these electrical differences if HDSP-H113 is selected.

Q: Are both substitute parts mechanically compatible with MAN6181C footprints? A: Yes. Both HDSP-5503 and HDSP-H113 use identical 10-DIP (0.600", 15.24mm) package configuration with common cathode pinout. PCB footprints are directly compatible.

Q: What is the wavelength difference between these parts? A: MAN6181C operates at 697nm (deep red), HDSP-5503 at 635nm (standard red), and HDSP-H113 at 645nm (standard red). These wavelength variations may produce slight color perception differences under identical viewing conditions.

Q: Are the substitute parts RoHS compliant? A: Both HDSP-5503 and HDSP-H113 are ROHS3 compliant. The original MAN6181C RoHS status is not specified in available documentation.

Q: Which substitute part should be selected for new designs? A: For new designs requiring direct electrical compatibility, select HDSP-5503. For power-constrained applications, select HDSP-H113. Both parts are active production status with confirmed long-term availability.
