MDA6310C Equivalent & Substitute Parts

Part Overview

The MDA6310C is a 14-segment alphanumeric LED display module manufactured by onsemi, featuring a 2-character yellow display in an 18-DIP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The display operates at 2.1V forward voltage with a 20mA test current and provides 4mcd brightness output at a 590nm peak wavelength. Finding suitable alternatives ensures design continuity and supply chain reliability for applications requiring dual-character alphanumeric display functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MDA6310C are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for valid substitution:

• Display Configuration: 2-character, 14-segment alphanumeric format
• Common Pin Type: Common Anode architecture
• Color: Yellow LED emission
• Character Size: 0.54" (13.72mm) alphanumeric segments
• Package Type: 18-DIP (0.600", 15.24mm) dual inline package
• Forward Voltage: 2.1V nominal operation
• Electrical Interface: Compatible with standard 18-DIP pinout and control logic

The LDD-E5403RI from Lumex Opto/Components Inc. meets these core substitution criteria, maintaining identical display format, common anode configuration, yellow color, character size, and package specifications. Variations in test current (10mA vs. 20mA), brightness rating (2.5mcd vs. 4mcd), and wavelength (585nm vs. 590nm) represent acceptable performance differences within the yellow LED spectrum and do not prevent functional substitution in typical applications.

Parameter Comparison

Engineering Selection Recommendations

The MDA6310C is classified as obsolete, necessitating transition to active product alternatives. The LDD-E5403RI is an active product from Lumex Opto/Components Inc. and represents a direct functional equivalent for new designs and production continuity.

Both components share identical core specifications: 2-character 14-segment alphanumeric display, common anode configuration, yellow color, 0.54" character size, 2.1V forward voltage, and 18-DIP package. Physical dimensions are within 0.008" (0.2mm) variation in height and width, with identical depth, ensuring PCB layout compatibility.

The LDD-E5403RI operates at 10mA test current compared to the MDA6310C's 20mA, resulting in lower power dissipation and reduced thermal load. The brightness differential (2.5mcd vs. 4mcd) and wavelength variation (585nm vs. 590nm) remain within the yellow LED spectrum and do not impact functional compatibility in standard display applications.

Both components maintain MSL 1 (Unlimited) moisture sensitivity classification and REACH Unaffected status, supporting equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the LDD-E5403RI directly replace the MDA6310C without PCB modifications?

A: Yes. Both components use identical 18-DIP (0.600", 15.24mm) package specifications with matching pinout architecture. Physical dimensions vary by less than 0.01" in height and width, permitting direct PCB substitution without layout changes.

Q: What is the impact of the 10mA vs. 20mA test current difference?

A: The LDD-E5403RI operates at lower test current, reducing power consumption and heat generation. This represents an improvement in efficiency and does not prevent functional substitution. Existing current-limiting resistor values in the circuit remain valid.

Q: Are there brightness or color perception differences between the two parts?

A: The LDD-E5403RI provides 2.5mcd brightness compared to the MDA6310C's 4mcd, with a wavelength difference of 5nm (585nm vs. 590nm). Both remain within the yellow LED spectrum. Brightness reduction may be perceptible in high-ambient-light environments but does not affect functional display operation in typical indoor applications.

Q: Do both components have identical moisture sensitivity and compliance certifications?

A: Yes. Both components are classified as MSL 1 (Unlimited) and maintain REACH Unaffected status, ensuring equivalent handling, storage, and regulatory compliance requirements.

Q: Is the LDD-E5403RI suitable for new product designs?

A: Yes. The LDD-E5403RI is classified as an active product, making it the appropriate choice for new designs requiring 2-character 14-segment alphanumeric yellow display functionality in an 18-DIP package.
