MDA6110C Equivalent & Substitute Parts

Part Overview

The MDA6110C is a 14-segment alphanumeric LED display module manufactured by onsemi, featuring a 2-character common anode configuration with red color output. 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 1.4mcd brightness output at a 697nm wavelength peak.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDA6110C is determined by strict alignment across the following critical parameters:

• Display Configuration: 2-character, 14-segment alphanumeric format
• Common Pin Type: Common anode architecture
• Character Size: 0.54" (13.72mm) digit/alpha size
• Package Type: 18-DIP (0.600", 15.24mm) form factor
• Electrical Specifications: Forward voltage (Vf) range 2.0V–2.1V, test current 20mA
• Color Category: Red or orange-red wavelength output (630nm–697nm range)
• Physical Envelope: Height, width, and depth within ±0.002" tolerance

The LTP-3786E from Lite-On Inc. meets all substitution criteria. It maintains identical character count, segment configuration, common anode topology, character size, and 18-DIP package specification. Electrical parameters remain within acceptable operating ranges, with forward voltage of 2.0V and test current of 20mA. Physical dimensions are equivalent within engineering tolerance. Color output shifts to orange-red (630nm) with increased brightness (2.3mcd), representing a functional enhancement rather than a deviation.

Parameter Comparison

Engineering Selection Recommendations

The LTP-3786E qualifies as a direct substitute for the MDA6110C based on product status and compliance considerations. The MDA6110C is classified as obsolete, creating supply chain risk for ongoing production and maintenance applications. The LTP-3786E maintains active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

Electrical compatibility is confirmed: the LTP-3786E forward voltage of 2.0V operates within the acceptable range relative to the MDA6110C specification of 2.1V. Test current remains constant at 20mA across both parts. Physical dimensions are equivalent within standard engineering tolerance, and the 18-DIP package footprint is identical, enabling direct PCB layout compatibility.

The shift from red (697nm) to orange-red (630nm) wavelength with increased brightness (2.3mcd versus 1.4mcd) represents a visual enhancement. This change is acceptable in applications where color perception and brightness consistency are not critical design constraints. For applications requiring exact red wavelength matching, this parameter difference must be evaluated against specific display requirements.

Frequently Asked Questions (FAQ)

Q: Can the LTP-3786E replace the MDA6110C in existing designs?

A: Yes. The LTP-3786E maintains identical character count, segment configuration, common anode topology, character size, and 18-DIP package specification. Electrical parameters (2.0V forward voltage, 20mA test current) are compatible. Physical dimensions are equivalent within engineering tolerance. Direct PCB substitution is feasible without layout modification.

Q: What is the primary difference between these two parts?

A: The MDA6110C is obsolete, while the LTP-3786E is active production. Color output differs: MDA6110C produces red at 697nm with 1.4mcd brightness; LTP-3786E produces orange-red at 630nm with 2.3mcd brightness. Forward voltage is 2.1V (MDA6110C) versus 2.0V (LTP-3786E).

Q: Are there packaging differences?

A: Both parts use 18-DIP (0.600", 15.24mm) package configuration. The MDA6110C ships in standard packaging; the LTP-3786E is supplied in tube packaging. Physical dimensions are equivalent within standard tolerance (height, width, depth differences are less than 0.002").

Q: Does the color shift from red to orange-red affect circuit design?

A: No circuit design changes are required. Both parts operate at compatible forward voltages and test currents. The color shift is a visual characteristic only and does not impact electrical performance, timing, or signal integrity. Applications requiring specific red wavelength output should evaluate this parameter against display requirements.

Q: What compliance certifications apply to the LTP-3786E?

A: The LTP-3786E is ROHS3 compliant and REACH affected. The MDA6110C compliance status is not specified in available documentation. For applications requiring specific regulatory compliance, the LTP-3786E certification status should be verified against project requirements.

Q: Is the increased brightness of the LTP-3786E (2.3mcd vs 1.4mcd) a concern?

A: No. Increased brightness represents a functional enhancement. Applications designed for 1.4mcd output will operate correctly with 2.3mcd brightness. If brightness consistency is critical, current-limiting resistor values may require adjustment to match original display intensity.
