Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MSQ6911C are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for valid substitution:

• Number of Characters: 4
• Digit/Alpha Size: 0.56" (14.22mm)
• Display Type: 7-Segment
• Common Pin Configuration: Common Anode
• Color: Red
• Voltage - Forward (Vf) (Typ): 2V
• Wavelength - Peak: 635nm
• Package / Case: 12-DIP

The LDQ-M514RI from Lumex Opto/Components Inc. meets all these core substitution criteria, making it a valid equivalent for the obsolete MSQ6911C.

Parameter Comparison

Engineering Selection Recommendations

The LDQ-M514RI is a direct functional equivalent to the MSQ6911C for applications requiring a quad red 7-segment common anode display in 12-DIP packaging. The substitute part maintains identical electrical characteristics for forward voltage and wavelength specifications, ensuring compatibility with existing circuit designs.

The LDQ-M514RI carries active product status from Lumex Opto/Components Inc., providing supply chain continuity and long-term availability compared to the obsolete MSQ6911C. The substitute part is RoHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and distribution.

Physical dimensions remain consistent between the two parts, with both occupying the same 12-DIP footprint suitable for standard PCB layouts. The LDQ-M514RI demonstrates higher luminous intensity (3.9mcd versus 2.2mcd) while operating at reduced test current (10mA versus 20mA), resulting in improved efficiency for display applications.

Frequently Asked Questions (FAQ)

Q: Can the LDQ-M514RI replace the MSQ6911C in existing designs?

A: Yes. Both parts share identical 7-segment display configuration, common anode pin arrangement, 0.56" character size, 2V forward voltage, 635nm wavelength, and 12-DIP package footprint. Circuit designs using the MSQ6911C can directly substitute the LDQ-M514RI without modification.

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

A: The LDQ-M514RI operates at 10mA test current compared to the MSQ6911C at 20mA, reducing power consumption per segment. The LDQ-M514RI provides higher luminous intensity at 3.9mcd versus 2.2mcd. Both parts maintain the same 2V forward voltage specification.

Q: Are there physical compatibility concerns with the LDQ-M514RI?

A: Both parts use 12-DIP packaging with identical PCB footprints. Physical dimensions are equivalent, with the LDQ-M514RI measuring 0.748" H x 1.980" W x 0.315" D compared to the MSQ6911C at 0.752" H x 1.988" W x 0.315" D. These minor dimensional variations do not affect PCB layout or mechanical assembly.

Q: What compliance certifications apply to the LDQ-M514RI?

A: The LDQ-M514RI is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component distribution and use.
