MAN6941C 7-Segment LED Display Equivalent & Substitute Parts

Part Overview

The MAN6941C is a dual-character 7-segment LED display module manufactured by onsemi, featuring a 0.56" red LED display in an 18-DIP package configuration. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The display operates at 2V forward voltage with a 20mA test current and delivers 2.2mcd brightness output at a 635nm wavelength peak.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAN6941C is determined by strict adherence to the following parameters:

• Display Configuration: 2-character, 7-segment, 0.56" digit size, red color, common cathode
• Package Type: 18-DIP (0.600", 15.24mm) form factor
• Electrical Characteristics: Forward voltage range 2V to 2.05V, test current 10mA to 20mA
• Physical Dimensions: Height 0.732" to 0.748", width 0.984", depth 0.315"
• Environmental Compliance: MSL 1 (Unlimited), REACH Unaffected status

The identified substitute parts meet these core substitution criteria and maintain functional and mechanical compatibility with the MAN6941C in standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

HDSP-523E (Broadcom Limited) is suitable for applications requiring active product status and RoHS3 compliance. This part delivers higher brightness output (4mcd) at a marginally elevated forward voltage (2.05V) and reduced power dissipation (62.5mW). The HDSP-523E maintains identical package geometry and electrical interface compatibility with the MAN6941C.

LDD-C514RI (Lumex Opto/Components Inc.) is suitable for applications prioritizing lower test current operation (10mA) and RoHS3 compliance. This part matches the MAN6941C in forward voltage (2V) and physical dimensions while delivering higher brightness (3.9mcd). The LDD-C514RI exhibits higher maximum power dissipation (105mW) due to its lower test current specification.

Both substitute parts maintain active product status, ensuring long-term availability and supply chain continuity compared to the obsolete MAN6941C.

Frequently Asked Questions (FAQ)

Q: Can HDSP-523E and LDD-C514RI be used interchangeably with MAN6941C?

A: Both parts are electrically and mechanically compatible substitutes for the MAN6941C in standard 18-DIP socket applications. Pin configuration, display format, and common cathode operation are identical across all three parts. Circuit design modifications are not required for substitution.

Q: What are the key differences between HDSP-523E and LDD-C514RI?

A: The HDSP-523E operates at 20mA test current with 4mcd brightness and 62.5mW maximum power dissipation. The LDD-C514RI operates at 10mA test current with 3.9mcd brightness and 105mW maximum power dissipation. Forward voltage is 2.05V for HDSP-523E and 2V for LDD-C514RI. Physical height differs slightly: 0.732" (HDSP-523E) versus 0.748" (LDD-C514RI).

Q: Are there compliance or certification differences between the substitute parts?

A: Both HDSP-523E and LDD-C514RI are RoHS3 compliant. The MAN6941C does not specify RoHS status. All three parts are REACH Unaffected and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the impact of different test current specifications on circuit design?

A: The LDD-C514RI operates at 10mA test current compared to 20mA for MAN6941C and HDSP-523E. Existing current-limiting resistor values in circuits designed for the MAN6941C may require adjustment when substituting the LDD-C514RI to maintain proper display brightness and segment visibility.

Q: Are physical dimension variations significant for PCB layout?

A: Height variation between HDSP-523E (0.732") and MAN6941C/LDD-C514RI (0.748") is 0.016" (0.4mm). Width and depth dimensions are identical across all parts. This minor height difference is typically not significant for standard PCB layouts but should be verified for space-constrained applications.
