MSQ6141C Equivalent & Substitute Parts

Part Overview

The MSQ6141C is a quad red 7-segment LED display module manufactured by onsemi, featuring a 0.56" character size in a 12-DIP package configuration. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The display operates as a common cathode configuration with a forward voltage of 2.1V and test current of 20mA, suitable for numeric and alphanumeric display applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSQ6141C is determined by the following critical parameters:

• Display Configuration: 4-character, 7-segment format with 0.56" character size
• Electrical Interface: Common cathode pin configuration
• Package Type: 12-DIP form factor
• Color Specification: Red LED wavelength
• Mechanical Compatibility: Physical dimensions and pin spacing must accommodate 12-DIP standard footprint

The LDQ-N514RI qualifies as a substitute based on matching all primary substitution criteria: identical character count, segment type, character size, common cathode configuration, red color, and 12-DIP package. Electrical parameters (forward voltage and test current) fall within acceptable operating ranges for common cathode 7-segment displays of this class.

Engineering Selection Recommendations

The LDQ-N514RI from Lumex Opto/Components Inc. is the qualified substitute for the obsolete MSQ6141C. Selection of this substitute is supported by:

• Product Status: LDQ-N514RI maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both components share identical REACH and ECCN classifications, maintaining compliance posture across supply chains
• Moisture Sensitivity: Both components carry MSL 1 (Unlimited) rating, indicating equivalent handling and storage requirements
• Mechanical Compatibility: Dimensions are within 0.004" variance across all axes, confirming PCB footprint compatibility with 12-DIP standard spacing

The LDQ-N514RI operates at lower forward voltage (2V vs. 2.1V) and reduced test current (10mA vs. 20mA), resulting in lower power dissipation characteristics suitable for modern low-power display applications.

Frequently Asked Questions (FAQ)

Q: Can the LDQ-N514RI be used as a direct replacement for MSQ6141C in existing designs?

A: Yes. Both components share identical 4-character, 0.56" 7-segment common cathode configuration in 12-DIP packaging. Pin assignments and electrical interface are compatible. Physical dimensions vary by less than 0.004" across all axes, confirming PCB footprint compatibility.

Q: What are the differences in electrical operation between these two parts?

A: The LDQ-N514RI operates at 2V forward voltage compared to 2.1V for the MSQ6141C, and requires 10mA test current versus 20mA. These differences result in lower power dissipation (105mW vs. 40mW rating). Peak wavelength differs (635nm vs. 697nm), which may produce slightly different color perception under identical drive conditions.

Q: Are there any compliance or regulatory differences?

A: No. Both components carry identical REACH Unaffected status, EAR99 ECCN classification, and MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and compliance posture remains unchanged when substituting the LDQ-N514RI.

Q: What is the significance of the product status difference?

A: The MSQ6141C is classified as obsolete, indicating onsemi has discontinued production. The LDQ-N514RI maintains active production status, ensuring reliable long-term availability and supply chain support for new designs and production continuity.

Q: Are there any package or pinout considerations?

A: Both components use 12-DIP packaging with 0.600" (15.24mm) standard pin spacing. Physical dimensions are nearly identical, with maximum variance of 0.004" across height, width, and depth. No PCB layout modifications are required for substitution.
