MAN6780 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The MAN6780 is a single-character red 7-segment LED display module manufactured by onsemi, housed in a 10-DIP package with common cathode configuration. This display is classified as obsolete, making equivalent and substitute parts necessary for new designs and production continuity. The MAN6780 operates at 2V forward voltage with 20mA test current and delivers 0.42mcd brightness at 650nm wavelength peak.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAN6780 is determined by the following critical parameters:

• Display Type & Configuration: All substitutes must be single-character 7-segment LED displays with common cathode configuration
• Package Type: All substitutes must use 10-DIP package format to ensure PCB compatibility
• Digit Size: Substitutes must maintain 0.56" (14.22mm) digit size for visual consistency
• Electrical Characteristics: Forward voltage (Vf), test current, and wavelength determine circuit compatibility and brightness performance
• Color: All substitutes are red LED displays
• Product Status: Active status substitutes ensure ongoing availability and supply chain reliability

The substitute parts are grouped into two categories based on electrical performance alignment:

Category A - Low Power Variants (1.7V, 5mA): HDSP-H103 and HDSP-H113 operate at reduced voltage and current, offering lower power dissipation and higher brightness efficiency (4.2mcd).

Category B - Standard Power Variants (2V, 10-20mA): HDSP-H213, LAP-601VL, and LDS-C5644RI maintain electrical characteristics closer to the original MAN6780 specification.

Parameter Comparison

Engineering Selection Recommendations

HDSP-H213 is the primary substitute for direct replacement in applications requiring 2V, 20mA operation. This Broadcom part maintains electrical specifications identical to the MAN6780, ensuring circuit compatibility without design modification. HDSP-H213 is ROHS3 compliant and actively produced, providing supply chain continuity.

HDSP-H103 and HDSP-H113 are suitable for designs where reduced power consumption is acceptable. Both parts operate at 1.7V and 5mA, delivering significantly lower power dissipation (37mW versus 480mW) while providing superior brightness (4.2mcd versus 0.42mcd). These Broadcom parts are ROHS3 compliant and actively produced. Circuit design must accommodate the lower voltage and current specifications.

LAP-601VL from Rohm Semiconductor offers the highest brightness rating (36mcd) and operates at 1.9V, 10mA. This part is suitable for applications requiring enhanced visibility. The 0.58" digit size represents a minor dimensional variation. LAP-601VL is ROHS3 compliant and actively produced.

LDS-C5644RI from Lumex Opto/Components Inc. operates at 2V, 10mA with 3.9mcd brightness. This part provides a middle-ground option between the original MAN6780 and lower-power alternatives. LDS-C5644RI is ROHS3 compliant and actively produced.

All substitute parts maintain common cathode configuration and 10-DIP package format, ensuring PCB footprint compatibility. Selection should be based on specific circuit voltage/current requirements and brightness performance needs.

Frequently Asked Questions (FAQ)

Q: Can HDSP-H103 or HDSP-H113 replace MAN6780 without circuit modification?

A: Direct replacement requires circuit design review. These parts operate at 1.7V and 5mA versus the MAN6780's 2V and 20mA. Current-limiting resistor values must be recalculated. Brightness will increase significantly (4.2mcd versus 0.42mcd), which may require optical filtering depending on application requirements.

Q: What is the primary difference between HDSP-H103 and HDSP-H113?

A: Both parts are electrically identical (1.7V, 5mA, 4.2mcd, 645nm). The difference is packaging: HDSP-H103 is supplied in Tube packaging, while HDSP-H113 is supplied in Bulk packaging. Select based on procurement and assembly requirements.

Q: Is LAP-601VL compatible with standard MAN6780 circuit designs?

A: LAP-601VL operates at 1.9V and 10mA, requiring circuit design adjustment. The 0.58" digit size is slightly larger than the MAN6780's 0.56", which may affect visual layout. The 10-DIP package format ensures PCB footprint compatibility. Circuit resistor values must be recalculated for the different voltage and current specifications.

Q: Why does LDS-C5644RI have a different package DIP spacing than other substitutes?

A: LDS-C5644RI uses 10-DIP (0.600", 15.24mm) spacing, identical to MAN6780. The LAP-601VL uses 10-DIP (0.400", 10.16mm) spacing, which is a narrower pitch. Verify PCB footprint compatibility before selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. HDSP-H103, HDSP-H113, HDSP-H213, LAP-601VL, and LDS-C5644RI are all ROHS3 compliant. The original MAN6780 RoHS status is not specified in available documentation.

Q: Which substitute offers the closest electrical match to MAN6780?

A: HDSP-H213 provides the closest electrical match, operating at identical 2V forward voltage and 20mA test current. This part requires no circuit design modification for voltage and current specifications.

Q: What is the brightness difference between MAN6780 and substitute parts?

A: MAN6780 delivers 0.42mcd. Substitutes range from 2.8mcd to 36mcd. HDSP-H103 and HDSP-H113 provide 10x brightness increase (4.2mcd). LAP-601VL provides 85x brightness increase (36mcd). This variation affects circuit design and may require optical attenuation in sensitive applications.
