MAN3H40 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The MAN3H40 is a 0.3-inch single-character red 7-segment LED display manufactured by onsemi in a 10-DIP package configuration. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The display operates as a common cathode device with a forward voltage of 2.05V and test current of 10mA, suitable for numeric and alphanumeric display applications in industrial and consumer electronics.

Substitute Part Grouping Explanation

Substitute parts for the MAN3H40 are qualified based on the following mandatory compatibility parameters:

Package / Case: 10-DIP (0.200", 5.08mm) — mechanical and electrical interface compatibility
Display Type: 7-Segment — functional equivalence
Number of Characters: 1 — single-character display requirement
Common Pin Configuration: Common Cathode — circuit topology compatibility
Color: Red — optical specification
Digit/Alpha Size: 0.30" (7.62mm) — visual footprint consistency

All substitute parts listed maintain these core parameters. Variations in forward voltage (Vf), test current, millicandela rating, wavelength peak, and power dissipation are permitted within the scope of common cathode 7-segment red LED display technology, provided the 10-DIP package and mechanical dimensions remain constant.

Engineering Selection Recommendations

All listed substitute parts are manufactured by Broadcom Limited and carry Active product status with ROHS3 compliance certification. The MAN3H40 is obsolete and no longer in production; therefore, selection of an active substitute is required for new designs and ongoing production support.

Selection among the substitute options depends on circuit design requirements:

HDSP-7503 and HDSP-A213 operate at 2V forward voltage with 20mA test current, providing electrical characteristics closest to the original MAN3H40 specification.
HDSP-7513 and HDSP-A113 operate at reduced forward voltage (1.7V) and test current (5mA), suitable for low-power applications.
HDSP-A103 provides identical electrical characteristics to HDSP-A113 with increased millicandela rating (3.6mcd).
HDSP-A153 operates at 1.8V with 20mA test current and delivers the highest brightness (14mcd) among all substitutes.

All substitutes maintain the 10-DIP package, common cathode configuration, 0.30-inch character size, and red color specification of the original MAN3H40.

Frequently Asked Questions (FAQ)

Q: Can HDSP-7503 directly replace MAN3H40 in existing circuits?

A: HDSP-7503 maintains identical package, pinout, and common cathode configuration. Forward voltage is 2V versus 2.05V on MAN3H40, and test current is 20mA versus 10mA. Circuit design must accommodate the higher current requirement. Brightness (5.39mcd) exceeds the original (1mcd).

Q: What is the difference between HDSP-A113 and HDSP-A103?

A: Both parts operate at 1.7V forward voltage and 5mA test current in 10-DIP common cathode configuration. HDSP-A103 is packaged in Tube format, while HDSP-A113 is packaged in Bulk. HDSP-A103 offers 3.6mcd brightness with 645nm wavelength peak. Electrical performance is equivalent; packaging differs.

Q: Which substitute offers the lowest power consumption?

A: HDSP-A103 and HDSP-A113 both deliver 37mW maximum power dissipation, the lowest among all substitutes. Both operate at 1.7V forward voltage and 5mA test current.

Q: Are all substitutes RoHS compliant?

A: Yes. All Broadcom Limited substitutes (HDSP-7503, HDSP-7513, HDSP-A103, HDSP-A113, HDSP-A153, HDSP-A213) carry ROHS3 Compliant certification. The original MAN3H40 RoHS status is not specified.

Q: Can I use HDSP-A153 for higher brightness applications?

A: HDSP-A153 delivers 14mcd brightness at 1.8V forward voltage and 20mA test current, the highest among all substitutes. It maintains 10-DIP common cathode configuration and 0.30-inch character size. Circuit design must accommodate 20mA current and 96mW power dissipation.

Q: What is the wavelength difference between substitutes?

A: Substitutes operate at two wavelength peaks: 635nm (HDSP-7503, HDSP-7513, HDSP-A213) and 645nm (HDSP-A103, HDSP-A113, HDSP-A153). The original MAN3H40 operates at 632nm. Wavelength variation affects perceived color tone within the red spectrum.
