MAN5R50 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The MAN5R50 is a single-character red 7-segment LED display module manufactured by onsemi, packaged in a 10-DIP (0.600", 15.24mm) configuration. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The display operates as a common anode device with a forward voltage of 2.05V and test current of 20mA, suitable for numeric display applications requiring a 0.51" character height.

Substitute Part Grouping Explanation

Substitution for the MAN5R50 is determined by strict adherence to the following electrical and mechanical parameters:

Package Compatibility: All substitute parts must use 10-DIP (0.600", 15.24mm) packaging to ensure direct PCB mounting without redesign
Display Configuration: Single-character, 7-segment, common anode topology is mandatory for circuit compatibility
Color: Red wavelength operation (635nm–650nm range) maintains visual consistency
Electrical Parameters: Forward voltage (Vf) range of 1.9V–2.05V and test current of 10mA–20mA are acceptable within standard LED driver circuit tolerances
Character Height: Digit sizes between 0.51" and 0.57" are mechanically compatible with standard display bezels and viewing windows

Three substitute parts meet these criteria: LAP-601VB (Rohm Semiconductor), LDS-A514RI (Lumex Opto/Components Inc.), and LDS-A5644RI (Lumex Opto/Components Inc.).

Engineering Selection Recommendations

LAP-601VB (Rohm Semiconductor): This substitute offers the lowest forward voltage (1.9V) and highest brightness (36mcd), making it suitable for applications requiring enhanced visibility. The part is ROHS3 compliant and carries active product status. The increased power dissipation (448mW) requires verification against circuit thermal design. Moisture sensitivity level MSL-3 (168 hours) is more restrictive than the original MAN5R50 and may impact storage and assembly conditions.

LDS-A514RI (Lumex Opto/Components Inc.): This substitute maintains electrical parameters closely aligned with the MAN5R50 (2V forward voltage, 10mA test current) and offers unlimited moisture sensitivity (MSL-1). The part is ROHS3 compliant with active product status. Character height (0.56") is slightly larger than the original, requiring mechanical fit verification in display windows. Brightness (3.9mcd) is lower than the original, suitable for applications with adequate ambient lighting.

LDS-A5644RI (Lumex Opto/Components Inc.): This substitute provides the most compact physical profile (0.673" height) while maintaining the same electrical characteristics as LDS-A514RI. ROHS3 compliance and MSL-1 rating apply. Brightness (4.6mcd) is the lowest among substitutes, appropriate for indoor or controlled-lighting environments. This option is optimal when space constraints require a smaller vertical footprint.

Frequently Asked Questions (FAQ)

Q: Can the LAP-601VB replace the MAN5R50 in existing PCB designs without modification?

A: Yes, the LAP-601VB uses identical 10-DIP (0.600", 15.24mm) packaging and common anode configuration, enabling direct pin-compatible substitution. However, the higher brightness (36mcd vs. 5.8mcd) and increased power dissipation (448mW vs. 60mW) require circuit current-limiting resistor adjustment and thermal evaluation.

Q: What is the primary difference between LDS-A514RI and LDS-A5644RI?

A: Both parts share identical electrical specifications (2V forward voltage, 10mA test current, 635nm wavelength). The key difference is physical height: LDS-A514RI measures 0.748" while LDS-A5644RI measures 0.673". Selection depends on available space within the display bezel or window.

Q: Are all substitute parts RoHS compliant?

A: Yes, all three substitute parts (LAP-601VB, LDS-A514RI, and LDS-A5644RI) are ROHS3 compliant. The original MAN5R50 RoHS status is not specified in available documentation.

Q: How does moisture sensitivity affect component selection?

A: The MAN5R50 and both Lumex substitutes carry MSL-1 (unlimited moisture sensitivity), allowing standard storage and assembly conditions. The LAP-601VB carries MSL-3 (168 hours), requiring controlled humidity storage and limiting shelf life after packaging opening. For applications with extended lead times or variable storage conditions, MSL-1 rated parts are preferred.

Q: Which substitute offers the closest electrical match to the MAN5R50?

A: LDS-A514RI provides the closest electrical alignment with forward voltage of 2V (vs. 2.05V original) and test current of 10mA. The wavelength (635nm) is within the red spectrum range of the original (639nm). This part is recommended for direct functional replacement with minimal circuit redesign.
