MAN6650 Equivalent & Substitute Parts

Part Overview

The MAN6650 is a 7-segment LED display module manufactured by onsemi, featuring a 0.56" orange character in a 1.5-digit configuration with common cathode architecture. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The display operates at a maximum forward voltage of 2.5V with a test current of 20mA and is housed in an 18-DIP package.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAN6650 is determined by strict alignment of the following critical parameters:

• Display Configuration: 7-segment, 1.5-digit format
• Character Size: 0.56" (14.22mm)
• Common Pin Type: Common cathode architecture
• Package Type: 18-DIP (0.600", 15.24mm)
• Physical Envelope: Dimensions must accommodate 0.750" H x 0.985" W x 0.315" D maximum
• Electrical Compatibility: Forward voltage and test current within acceptable operating ranges
• Color Specification: Orange or orange-red wavelength (630nm)

The LTD-6650E from Lite-On Inc. meets all substitution criteria, maintaining identical display configuration, package type, and physical dimensions while operating within compatible electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The LTD-6650E qualifies as a direct substitute for the MAN6650 based on product status and compliance considerations. The MAN6650 is classified as obsolete, whereas the LTD-6650E maintains active product status, ensuring continued availability and supply chain reliability. The LTD-6650E carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution. Both components share identical package specifications, pin configurations, and physical envelopes, enabling direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the LTD-6650E replace the MAN6650 in existing designs?

A: Yes. Both components feature identical 18-DIP package specifications, common cathode configuration, 1.5-digit 7-segment display format, and 0.56" character size. Physical dimensions are equivalent within manufacturing tolerances (0.984" vs. 0.985" width difference is negligible). Electrical parameters are compatible, with the LTD-6650E operating at 2V forward voltage compared to the MAN6650's 2.5V maximum, representing a favorable operating margin.

Q: What are the key differences between these parts?

A: The primary differences are product status and compliance. The MAN6650 is obsolete, while the LTD-6650E is active. The LTD-6650E carries ROHS3 compliance certification. The LTD-6650E exhibits slightly lower power dissipation (75mW vs. 1.05W) and marginally higher brightness (2.4mcd vs. 2.2mcd). Color specification is orange-red versus orange, both at 630nm wavelength.

Q: Are there any circuit design considerations for substitution?

A: No design modifications are required. Both components operate at 20mA test current with common cathode architecture. The LTD-6650E's lower forward voltage (2V vs. 2.5V) may reduce current-limiting resistor values slightly, but existing designs will function without adjustment.

Q: What is the package compatibility status?

A: Both components use 18-DIP (0.600", 15.24mm) packaging with identical pinout and physical envelope specifications. Direct PCB substitution is possible without layout changes or mechanical modifications.
