MDA6910C Equivalent & Substitute Parts

Part Overview

The MDA6910C 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 2V forward voltage with 20mA test current and is housed in an 18-DIP package measuring 0.835" H x 0.996" W x 0.307" D.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDA6910C is determined by the following critical parameters:

• Display Configuration: 2-character, 14-segment alphanumeric module
• Common Pin Type: Common anode architecture
• Package Type: 18-DIP form factor
• Character Size: 0.54" (13.72mm) digit/alpha size
• Electrical Specifications: 2V forward voltage, 20mA test current
• Mechanical Compatibility: Physical dimensions within acceptable tolerance for PCB mounting

The LTP-3786E from Lite-On Inc. qualifies as a substitute part based on matching all critical parameters. While color output differs (orange-red vs. red), the electrical interface, package configuration, and mechanical form factor remain compatible with the original MDA6910C design.

Parameter Comparison

Engineering Selection Recommendations

The LTP-3786E is the designated substitute for the obsolete MDA6910C. Selection of this alternative is supported by the following factors:

• Product Status: The LTP-3786E maintains active product status with current manufacturing support, whereas the MDA6910C is obsolete and subject to availability constraints.
• Compliance Certifications: The LTP-3786E is RoHS3 compliant and REACH affected, providing regulatory alignment for new designs. The MDA6910C is REACH unaffected due to its obsolete status.
• Electrical Compatibility: Both parts operate at identical forward voltage (2V) and test current (20mA), ensuring direct circuit compatibility without modification to drive electronics.
• Package Compatibility: Both components utilize 18-DIP packaging with dimensions within 0.002" tolerance, permitting direct PCB footprint substitution.
• Optical Characteristics: The LTP-3786E produces orange-red output (630nm peak wavelength) compared to the MDA6910C red output (635nm peak wavelength). The brightness differential (2.3mcd vs. 4mcd) and reduced power dissipation (75mW vs. 90mW) are secondary considerations dependent on application requirements.

Frequently Asked Questions (FAQ)

Q: Can the LTP-3786E be used as a direct replacement for the MDA6910C without circuit modifications?

A: Yes. Both parts share identical electrical specifications (2V forward voltage, 20mA test current) and 18-DIP package configuration. No circuit modifications are required for electrical compatibility.

Q: What is the primary difference between these two display modules?

A: The primary difference is color output. The MDA6910C produces red light at 635nm peak wavelength with 4mcd brightness, while the LTP-3786E produces orange-red light at 630nm peak wavelength with 2.3mcd brightness. The LTP-3786E also exhibits lower maximum power dissipation (75mW vs. 90mW).

Q: Are there mechanical compatibility concerns when substituting the LTP-3786E for the MDA6910C?

A: No. Physical dimensions are within acceptable tolerance. The MDA6910C measures 0.835" H x 0.996" W x 0.307" D, while the LTP-3786E measures 0.833" H x 0.992" W x 0.307" D. Both use 18-DIP packaging with 0.600" (15.24mm) pin spacing, permitting direct PCB footprint compatibility.

Q: What is the moisture sensitivity level for both parts?

A: Both the MDA6910C and LTP-3786E are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Why is the MDA6910C listed as obsolete?

A: The MDA6910C is classified as obsolete by onsemi, indicating discontinued manufacturing and limited availability. The LTP-3786E from Lite-On Inc. is an active product with current production support.

Q: Does the LTP-3786E meet current regulatory requirements?

A: Yes. The LTP-3786E is RoHS3 compliant and REACH affected, meeting current regulatory standards for electronic components in most jurisdictions.
