Color: Green
Package / Case: 10-DIP (0.300", 7.62mm)
Digit/Alpha Size: 0.39" to 0.40" (10.00mm to 10.16mm)

Electrical Tolerance Range:

Forward Voltage (Vf): 2.1V to 2.25V

Engineering Selection Recommendations

For Direct Replacement (Highest Compatibility): The SA39-11CGKWA and SA39-11GWA from Kingbright provide the closest electrical and mechanical match to the MAN442C. Both maintain the 0.39" digit height, common anode configuration, and 10-DIP package. SA39-11CGKWA matches the original 2.1V forward voltage and 20mA test current specification. Both Kingbright parts are ROHS3 compliant and carry active product status, ensuring long-term availability and supply chain stability.

For Lower Power Applications: The LA-401MD from Rohm Semiconductor operates at reduced test current (10mA) with lower power dissipation (60mW), suitable for battery-powered or power-constrained designs. This part maintains the 2.1V forward voltage of the original MAN442C and delivers significantly higher brightness (16mcd), providing design flexibility for reduced-brightness applications.

For Enhanced Brightness: The HDSP-301G from Broadcom Limited offers increased brightness (2.8mcd) with slightly elevated forward voltage (2.25V) and power dissipation (105mW). This part accommodates applications requiring higher visibility in ambient light conditions while maintaining 10-DIP package compatibility.

For Exact Dimensional Match: The LDS-A3902RI from Lumex Opto/Components Inc. maintains identical physical dimensions (0.512" H x 0.394" W x 0.276" D) and 0.39" digit height to the MAN442C. This part operates at 2.2V forward voltage with 10mA test current, suitable for designs with strict mechanical envelope constraints.

All substitute parts carry ROHS3 compliance and active product status, ensuring regulatory conformance and production availability.

Frequently Asked Questions (FAQ)

Q: Can the MAN442C be directly replaced with any of these substitute parts? A: Yes. All substitute parts share the same 10-DIP package footprint, common anode pin configuration, and green 7-segment display type. Pin-for-pin replacement is possible without circuit modification. Electrical parameter variations (forward voltage, test current, brightness) fall within acceptable operating ranges for standard display applications.

Q: What is the difference between the Kingbright SA39-11CGKWA and SA39-11GWA? A: Both parts are Kingbright 0.39" green 7-segment common anode displays in 10-DIP packages. The SA39-11CGKWA operates at 2.1V with 21mcd brightness, while the SA39-11GWA operates at 2.2V with 6.4mcd brightness. The SA39-11CGKWA provides higher brightness and closer voltage matching to the original MAN442C specification.

Q: Which substitute offers the lowest power consumption? A: The LA-401MD from Rohm Semiconductor delivers the lowest power dissipation at 60mW with a 10mA test current. This part is suitable for applications where power efficiency is a primary design constraint.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All five substitute parts listed carry ROHS3 compliance certification, meeting current environmental and regulatory requirements for electronic components.

Q: What is the brightness difference between the MAN442C and substitute parts? A: The MAN442C is rated at 2mcd. Substitute parts range from 2.5mcd (LDS-A3902RI) to 21mcd (SA39-11CGKWA). Higher millicandela ratings indicate increased brightness. Selection depends on application visibility requirements and ambient light conditions.

Q: Can I use the HDSP-301G if my circuit is designed for 2.1V forward voltage? A: The HDSP-301G operates at 2.25V forward voltage, a 0.15V increase from the MAN442C specification. This difference is typically accommodated by standard LED current-limiting resistor designs. Circuit verification is necessary to confirm compatibility with your specific resistor values and power supply configuration.

Q: Which substitute part has the closest physical dimensions to the MAN442C? A: The SA39-11CGKWA and SA39-11GWA maintain identical physical dimensions (0.512" H x 0.394" W x 0.276" D) and 0.39" digit height to the MAN442C. The LDS-A3902RI also matches these dimensions exactly.

Q: What is the wavelength difference between parts, and does it matter? A: Wavelength variations range from 563nm (LA-401MD) to 574nm (SA39-11CGKWA), representing different shades of green within the visible spectrum. For most applications, these differences are imperceptible to the human eye. Selection based on wavelength is necessary only for color-critical or multi-display matching applications.
