MAN6750 Equivalent & Substitute Parts

Part Overview

The MAN6750 is a 7-segment LED display module manufactured by onsemi, featuring a 0.56" red digit with 1.5 character capacity in a common cathode configuration. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The display operates at 2V maximum forward voltage with 20mA test current and is housed in an 18-DIP package with 15 leads.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAN6750 is determined by strict alignment with the following electrical and mechanical parameters:

• Display Configuration: 7-segment, 1.5 character, common cathode topology
• Digit Size: 0.56" (14.22mm) nominal dimension
• Color: Red wavelength range
• Electrical Specifications: Forward voltage 2V nominal, test current 20mA
• Package: 18-DIP form factor with 15-lead configuration
• Physical Envelope: Height 0.750", width approximately 0.985", depth 0.315"

The LTD-6750P from Lite-On Inc. meets all primary substitution criteria, maintaining identical display type, character count, digit size, color, common cathode configuration, voltage rating, current specification, and package form factor. Minor dimensional variance (0.984" vs 0.985" width) and wavelength differences (697nm vs 650nm) remain within acceptable tolerance for mechanical and optical compatibility.

Engineering Selection Recommendations

The LTD-6750P is a direct functional substitute for the MAN6750. Selection should be based on the following factors:

Product Status: The MAN6750 is obsolete, while the LTD-6750P maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: The LTD-6750P carries RoHS3 compliance certification, meeting current environmental and regulatory standards. Both parts are classified as REACH Unaffected and carry EAR99 ECCN designation.

Electrical Compatibility: Both parts operate at identical voltage and current specifications (2V forward, 20mA test current), ensuring direct circuit compatibility without modification to drive electronics or current-limiting resistor calculations.

Mechanical Fit: Dimensional compatibility is confirmed across all critical parameters. The 0.001" width variance (0.984" vs 0.985") is within standard PCB layout tolerance and does not affect mounting or mechanical clearance.

Optical Characteristics: Wavelength difference (697nm vs 650nm) represents a shift within the red spectrum. Both wavelengths are perceptually red to the human eye; however, applications requiring specific wavelength matching should evaluate this parameter against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the LTD-6750P be used as a direct replacement for the MAN6750 without circuit modification?

A: Yes. Both parts share identical electrical specifications (2V forward voltage, 20mA test current) and common cathode configuration. No changes to drive circuitry, current-limiting resistors, or control logic are required.

Q: Are there any physical compatibility concerns with the LTD-6750P?

A: No. The 18-DIP package form factor, lead spacing (0.600"), and overall dimensions are compatible. The 0.001" width difference is within standard PCB tolerance and does not affect mounting or clearance.

Q: How do the wavelength specifications differ, and does this matter?

A: The MAN6750 peaks at 650nm while the LTD-6750P peaks at 697nm. Both are within the red spectrum and appear red to human perception. Applications with wavelength-specific requirements (such as optical sensing or color-matched displays) should evaluate this parameter against system specifications.

Q: What is the inventory status for these parts?

A: The MAN6750 has 1047 units in stock but is obsolete. The LTD-6750P has 849 units in stock and maintains active production status, providing better long-term availability.

Q: Are there compliance or regulatory differences between these parts?

A: The LTD-6750P carries RoHS3 compliance certification. Both parts are REACH Unaffected and carry identical ECCN and HTSUS classifications, meeting current regulatory requirements.
