MAN72A 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The MAN72A is a single-character red 7-segment LED display manufactured by Everlight Electronics Co Ltd. This component is classified as a Display Module for LED character and numeric applications. The device features a common anode configuration with a 0.30" (7.62mm) digit height, designed for standard DIP packaging in 14-pin configuration. The product maintains Active status and is RoHS3 compliant, making it suitable for current industrial and consumer electronics applications. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for this display category.

Substitute Part Grouping Explanation

Substitution eligibility for the MAN72A is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Display Type: Must be 7-Segment
• Number of Characters: Must be 1 (single character)
• Common Pin Configuration: Must be Common Anode
• Color: Must be Red
• Package / Case: Must be 14-DIP (0.300", 7.62mm)
• Voltage - Forward (Vf): Operating range 2.0V to 2.2V
• Current - Test: 20mA nominal
• RoHS Status: ROHS3 Compliant

Secondary Consideration Parameters:

• Digit/Alpha Size: Allowable range 0.30" to 0.43" (7.62mm to 10.92mm)
• Wavelength - Peak: Red spectrum 635nm to 660nm
• Millicandela Rating: Brightness variation acceptable within product category

The LDS-A414RI from Lumex Opto/Components Inc. qualifies as a substitute part based on conformance to all primary criteria and acceptable variation within secondary parameters.

Engineering Selection Recommendations

Primary Selection - MAN72A: The MAN72A is the specified component for applications requiring a 0.30" red 7-segment common anode display with 2.2V forward voltage and 660nm peak wavelength. This part maintains Active product status and full RoHS3 compliance. Selection is appropriate for designs with established PCB layouts and component qualification.

Substitute Selection - LDS-A414RI: The LDS-A414RI qualifies as a functional substitute when the following conditions are met:

1. PCB layout accommodates the larger 0.43" digit height (10.92mm vs. 7.62mm)
2. Circuit design accepts the lower forward voltage of 2.0V
3. Visual appearance difference due to 635nm wavelength (slightly more orange-red tone compared to 660nm) is acceptable for the application
4. The 11-lead configuration within the 14-DIP package is compatible with the circuit design

Both parts maintain Active product status and ROHS3 compliance. Selection between these parts is determined by physical space constraints, voltage tolerance, and visual appearance requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the LDS-A414RI be used as a direct pin-for-pin replacement for the MAN72A?

A: Both parts use 14-DIP (0.300", 7.62mm) packaging with common anode configuration. The LDS-A414RI uses 11 leads within the 14-pin package. Pin compatibility requires verification against the specific circuit schematic and PCB layout. The larger physical dimensions (0.43" vs. 0.30" digit height) may affect PCB mounting clearances.

Q: What is the difference in brightness between these two displays?

A: The MAN72A has a millicandela rating of 0.35mcd, while the LDS-A414RI has a rating of 3.9mcd. The LDS-A414RI is significantly brighter. Application requirements determine whether this brightness difference is acceptable or requires circuit current adjustment.

Q: Are there voltage compatibility concerns when substituting?

A: The MAN72A operates at 2.2V typical forward voltage, while the LDS-A414RI operates at 2.0V typical. Both are within acceptable red LED operating ranges. Circuit designs must accommodate this 0.2V difference in current-limiting resistor calculations to maintain the 20mA test current specification.

Q: How does the wavelength difference affect color appearance?

A: The MAN72A emits at 660nm (pure red), while the LDS-A414RI emits at 635nm (red-orange). This difference is visible to the human eye. Applications where color consistency is critical should maintain the original MAN72A specification.

Q: What are the physical space implications of using the LDS-A414RI?

A: The LDS-A414RI has larger overall dimensions: 0.748" H x 0.496" W x 0.307" D compared to the MAN72A at 0.738" H x 0.386" W x 0.200" D. PCB layout must provide adequate clearance for the larger width (0.496" vs. 0.386") and depth (0.307" vs. 0.200").

Q: Are both parts suitable for new designs?

A: Both the MAN72A and LDS-A414RI maintain Active product status and are in current production. Either part is suitable for new designs, provided the specific electrical and mechanical requirements of the application are met.
