MAN5750 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The MAN5750 is a single-character red 7-segment LED display manufactured by onsemi, featuring a 0.51" digit height in a 10-DIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and production continuity. The display operates as a common anode configuration with a forward voltage of 1.6V and test current of 20mA, suitable for numeric display applications requiring compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAN5750 is determined by the following critical parameters:

• Package Compatibility: All substitute parts must use 10-DIP (0.600", 15.24mm) packaging to ensure direct PCB footprint compatibility
• Display Configuration: Common anode, single-character, 7-segment red LED display
• Electrical Characteristics: Forward voltage (Vf), test current, and power dissipation must be within acceptable operating ranges for the target application
• Optical Properties: Wavelength and brightness (millicandela rating) determine visual performance
• Physical Dimensions: Digit height and overall package size affect mechanical fit and visual integration

The substitute parts listed below maintain the 10-DIP package standard and common anode configuration, ensuring functional compatibility with existing circuit designs. Variations in forward voltage, current requirements, and brightness characteristics are documented to support engineering selection based on specific application needs.

Parameter Comparison

Engineering Selection Recommendations

LAP-601VB (Rohm Semiconductor) is an active product with ROHS3 compliance, offering higher brightness (36mcd) and lower test current (10mA) compared to the MAN5750. The increased forward voltage (1.9V) and slightly larger digit height (0.57") require circuit design verification. This substitute is suitable for applications where higher brightness and reduced power consumption are beneficial.

LDS-A5644RI (Lumex Opto/Components Inc.) is an active product with ROHS3 compliance and MSL 1 rating matching the original part. The forward voltage is 2V with reduced test current (10mA) and significantly lower power dissipation (105mW). The digit height (0.56") is comparable to the MAN5750. This substitute provides improved power efficiency and is suitable for battery-powered or thermally constrained applications.

Both substitute parts maintain the 10-DIP package standard and common anode configuration. Selection between substitutes depends on application requirements for brightness, power consumption, and forward voltage tolerance in the driving circuit.

Frequently Asked Questions (FAQ)

Q: Can the LAP-601VB or LDS-A5644RI be used as direct drop-in replacements for the MAN5750?

A: Both parts share the 10-DIP package footprint and common anode configuration, enabling PCB-level compatibility. However, circuit design verification is required due to differences in forward voltage (1.9V and 2V respectively versus 1.6V for the MAN5750) and test current specifications. Existing current-limiting resistor values may require adjustment.

Q: What are the key differences in brightness between these parts?

A: The MAN5750 has a millicandela rating of 0.5mcd, the LAP-601VB provides 36mcd, and the LDS-A5644RI provides 4.6mcd. The LAP-601VB offers significantly higher brightness, while the LDS-A5644RI provides moderate brightness improvement. Application visibility requirements determine the appropriate selection.

Q: Are there physical size considerations when substituting these parts?

A: The MAN5750 has a digit height of 0.51" (13.00mm). The LAP-601VB is 0.57" (14.60mm) and the LDS-A5644RI is 0.56" (14.22mm). These dimensional differences may affect visual alignment in display panels or enclosures with tight mechanical tolerances.

Q: What is the impact of different forward voltages on circuit design?

A: The MAN5750 operates at 1.6V (Typ), while substitutes operate at 1.9V (LAP-601VB) and 2V (LDS-A5644RI). Higher forward voltages require proportionally higher supply voltages or adjusted current-limiting resistor values to maintain desired brightness and current levels. Circuit simulation or testing is necessary to confirm compatibility with existing power supplies.

Q: Which substitute is recommended for low-power applications?

A: The LDS-A5644RI has the lowest power dissipation at 105mW (Max) and operates at 10mA test current, making it suitable for battery-powered or energy-constrained designs. The LAP-601VB also operates at 10mA but has higher power dissipation at 448mW.

Q: Are both substitutes RoHS compliant?

A: Yes, both the LAP-601VB and LDS-A5644RI are ROHS3 compliant. The MAN5750 RoHS status is not specified in the provided data.
