MAN6980 LED 7-Segment Display - Equivalent & Substitute Parts

Part Overview

The MAN6980 is a red 7-segment LED display module manufactured by onsemi, featuring a 0.56" character size in a 10-DIP package configuration. This single-character common cathode display operates at a maximum forward voltage of 2.5V with a test current of 20mA and delivers 2.2 millicandela brightness at a peak wavelength of 635nm.

The MAN6980 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or repair requirements for legacy systems utilizing this display module.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAN6980 is determined by the following critical parameters:

• Display Type: 7-Segment configuration (single character)
• Common Pin Configuration: Common Cathode
• Color: Red (635nm wavelength band)
• Package / Case: 10-DIP (0.600", 15.24mm) footprint
• Character Size: 0.56" (14.22mm) nominal dimension
• Electrical Compatibility: Forward voltage and test current within acceptable operating ranges for legacy circuit designs

Substitute parts must maintain identical package footprint and pin configuration to ensure direct PCB compatibility. Forward voltage, current, and brightness parameters may vary within the constraints of the original design's power supply and current-limiting resistor specifications.

Engineering Selection Recommendations

Primary Substitute: SC56-11EWA (Kingbright)

The SC56-11EWA is the preferred substitute for the MAN6980. It maintains identical package footprint, pin configuration, character size, and common cathode topology. Operating parameters (2V forward voltage, 20mA test current) align closely with the original design specifications. The part is in active production status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

Secondary Substitute: LTS-6980HR (Lite-On)

The LTS-6980HR provides direct functional equivalence with matching forward voltage (2V) and test current (20mA) specifications. Physical dimensions and package configuration are identical. This part is actively manufactured and ROHS3 compliant. REACH status indicates material compliance requirements apply.

Alternative Substitute: HDSP-5553 (Broadcom)

The HDSP-5553 maintains package compatibility and common cathode configuration. However, it operates at reduced forward voltage (1.7V) and test current (5mA), resulting in significantly lower power dissipation (52mW versus 600mW for the original). This part is suitable only for designs where the original power supply and current-limiting resistor values can be recalculated to accommodate lower operating parameters. ROHS3 compliance is confirmed.

All substitute parts are available in active production status, ensuring component availability for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-5553 be used as a direct drop-in replacement for the MAN6980?

A: The HDSP-5553 shares identical package footprint and pin configuration, enabling physical installation in the same PCB location. However, electrical parameters differ significantly. The HDSP-5553 operates at 1.7V forward voltage and 5mA test current, compared to the MAN6980's 2.5V maximum and 20mA specification. Direct substitution without circuit modification may result in insufficient display brightness or circuit malfunction. Current-limiting resistor values must be recalculated based on the actual power supply voltage and desired operating current.

Q: What is the primary difference between common cathode and common anode 7-segment displays?

A: The MAN6980 and all listed substitutes are common cathode devices. In common cathode configuration, the cathode pin is connected to ground, and individual segment anodes are driven high to illuminate. This configuration is not interchangeable with common anode displays, where the anode is connected to the positive supply and segments are driven low. Pin-level compatibility requires matching common pin topology.

Q: Are all substitute parts RoHS compliant?

A: Yes. The SC56-11EWA, LTS-6980HR, and HDSP-5553 are all ROHS3 compliant. The original MAN6980 RoHS status is not specified in the available documentation.

Q: What is the significance of the 10-DIP package specification?

A: The 10-DIP (0.600", 15.24mm) package designation indicates a dual-in-line package with 10 pins spaced 0.1" apart. This standardized footprint ensures mechanical and electrical compatibility across all listed substitute parts. PCB layout modifications are not required when substituting between parts with identical package specifications.

Q: How do brightness ratings (millicandela) affect display visibility?

A: The MAN6980 is rated at 2.2mcd, while the SC56-11EWA delivers 6.4mcd at identical test current. Higher millicandela ratings indicate greater luminous intensity. The SC56-11EWA provides approximately 3x greater brightness under standard test conditions. Design requirements for ambient light conditions and viewing distance determine whether increased brightness is beneficial or requires adjustment of current-limiting resistor values to reduce power consumption.

Q: Can the SC52-11EWA (0.52" character size) substitute for the MAN6980 (0.56" character size)?

A: The SC52-11EWA is not a direct substitute. Although it shares the same 10-DIP package footprint and common cathode configuration, the character size is 0.52" (13.21mm) versus the MAN6980's 0.56" (14.22mm). This dimensional difference affects display visibility and may not meet design specifications for character legibility or panel cutout dimensions. Substitution is not recommended without explicit design review.
