MAN8240 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The MAN8240 is a single-character red 7-segment LED display module manufactured by onsemi, featuring a 0.80" digit size in an 18-DIP package configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The display operates at 1.8V forward voltage with a 20mA test current, suitable for numeric and alphanumeric display applications requiring common cathode configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAN8240 is determined by the following critical parameters:

• Display Type & Configuration: Must be 7-segment, single character, common cathode
• Digit Size: Must be 0.80" (20.32mm) to maintain visual consistency and PCB layout compatibility
• Electrical Specifications: Forward voltage 1.8V and test current 20mA establish the operational envelope
• Package Type: 18-DIP (0.600", 15.24mm) ensures mechanical and electrical pin compatibility
• Color: Red wavelength in the 645–650nm range

The HDSP-N153 manufactured by Broadcom Limited meets all substitution criteria. Both parts share identical digit size, common cathode configuration, electrical operating parameters, and package footprint. The HDSP-N153 is classified as active product status, providing long-term availability advantage over the obsolete MAN8240.

Engineering Selection Recommendations

The HDSP-N153 is the direct functional equivalent for MAN8240 replacement. Selection rationale is based on the following factors:

Product Status & Availability: The MAN8240 is obsolete, whereas the HDSP-N153 maintains active product status, ensuring continued supply chain access and manufacturing support.

Regulatory Compliance: The HDSP-N153 carries ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions. Both parts are REACH Unaffected and classified under ECCN EAR99.

Electrical & Mechanical Compatibility: Identical forward voltage (1.8V), test current (20mA), digit size (0.80"), common cathode configuration, and 18-DIP package footprint ensure direct PCB compatibility without circuit redesign.

Performance Characteristics: The HDSP-N153 provides higher luminous intensity (14mcd versus 3.3mcd), offering improved visibility in applications requiring greater brightness. Peak wavelength difference (645nm versus 650nm) remains within the red spectrum and is imperceptible to human vision in typical display applications.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-N153 be used as a direct replacement for MAN8240 without PCB modifications?

A: Yes. Both parts share identical digit size (0.80"), common cathode configuration, forward voltage (1.8V), test current (20mA), and 18-DIP package footprint. No circuit redesign is required.

Q: What is the difference in lead count between MAN8240 and HDSP-N153?

A: The MAN8240 features 14 leads while the HDSP-N153 features 12 leads, both within the 18-DIP package. This difference reflects internal segment routing but does not affect functional compatibility or pin assignment for standard 7-segment display operation.

Q: How do the brightness specifications compare?

A: The HDSP-N153 provides 14mcd luminous intensity compared to the MAN8240's 3.3mcd. This represents approximately 4.2× greater brightness, which may require adjustment of series current-limiting resistors if the original design was optimized for the lower brightness of the MAN8240.

Q: Are there wavelength compatibility concerns?

A: The MAN8240 peak wavelength is 650nm while the HDSP-N153 is 645nm. Both fall within the red spectrum and produce visually identical color appearance in human perception. No optical filtering or compensation is necessary.

Q: What compliance advantages does the HDSP-N153 offer?

A: The HDSP-N153 is ROHS3 compliant, meeting current environmental regulations. The MAN8240 compliance status is not specified. Both parts are REACH Unaffected and carry identical ECCN and HTSUS classifications.
