MAN6910 Equivalent & Substitute Parts

Part Overview

The MAN6910 is a dual-character 7-segment LED display module manufactured by Everlight Electronics Co Ltd. This red LED display operates at a maximum forward voltage of 2.5V with a test current of 20mA and features a 0.56" character height in a common anode configuration. The module is housed in an 18-DIP package with dimensions of 0.750" H x 0.985" W x 0.315" D (19.05mm x 25.02mm x 8.00mm).

The MAN6910 maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Finding equivalent substitute parts is necessary when the primary component becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits component optimization within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAN6910 is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Number of Characters: 2
• Display Type: 7-Segment
• Common Pin Configuration: Common Anode
• Color: Red
• Character Height: 0.56" (14.22mm)
• Package / Case: 18-DIP (0.600", 15.24mm)

Allowable Parameter Variations: Substitute parts must operate within the electrical specifications of the application circuit. Forward voltage (Vf), current rating, millicandela rating, wavelength, and power dissipation may vary within the design constraints of the target application, provided the substitute part maintains compatibility with the 18-DIP footprint and common anode pin configuration.

The HDSP-521E from Broadcom Limited qualifies as a direct substitute based on matching all mandatory parameters while offering different electrical characteristics within acceptable operating ranges.

Parameter Comparison

Engineering Selection Recommendations

Both the MAN6910 and HDSP-521E maintain Active product status and are RoHS3 compliant, ensuring regulatory compliance for current applications. The HDSP-521E offers lower forward voltage (2.05V versus 2.5V maximum) and significantly reduced power dissipation (62.5mW versus 1.2W), which may provide advantages in power-constrained applications. The HDSP-521E also provides higher luminous intensity (4mcd versus 2.2mcd), resulting in improved display brightness.

Both parts are packaged identically in 18-DIP format with matching pin spacing (0.600", 15.24mm) and footprint dimensions, enabling direct PCB substitution without layout modifications. The wavelength difference (640nm versus 635nm) represents a negligible shift within the red spectrum and does not affect visual appearance or functional compatibility.

Selection between these parts should be based on specific application requirements regarding forward voltage tolerance, power budget constraints, and desired brightness levels. Both parts are suitable for direct substitution in common anode 7-segment display applications requiring dual-character red LED modules.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-521E replace the MAN6910 in existing designs without PCB modifications?

A: Yes. Both parts use identical 18-DIP packaging with 0.600" (15.24mm) pin spacing. The footprint and pinout are compatible, enabling direct substitution without PCB layout changes.

Q: What is the significance of the forward voltage difference between these parts?

A: The MAN6910 specifies a maximum forward voltage of 2.5V, while the HDSP-521E operates at 2.05V typical. This difference affects current-limiting resistor calculations in the drive circuit. Applications designed for the MAN6910 must verify that the lower forward voltage of the HDSP-521E does not cause excessive current draw through existing resistor networks.

Q: Why does the HDSP-521E have lower power dissipation despite identical test current?

A: Power dissipation is calculated as the product of forward voltage and current. The HDSP-521E's lower forward voltage (2.05V) results in lower total power dissipation (62.5mW) compared to the MAN6910 (1.2W) at the same 20mA test current.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS3 compliant with MSL 1 (unlimited moisture sensitivity). The HDSP-521E includes REACH Unaffected status. Both parts carry EAR99 ECCN classification.

Q: How do the brightness levels compare?

A: The HDSP-521E provides 4mcd brightness versus 2.2mcd for the MAN6910. This represents approximately 82% higher luminous intensity, resulting in a brighter display output at equivalent drive currents.

Q: Is the wavelength difference between 635nm and 640nm visually perceptible?

A: No. Both wavelengths fall within the red spectrum range. The 5nm difference is not visually distinguishable to the human eye and does not affect color matching or display appearance in practical applications.
