MAN6660 Equivalent & Substitute Parts

Part Overview

The MAN6660 is a single-character 7-segment LED display module manufactured by onsemi, featuring orange color output with common anode configuration. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The display operates at a maximum forward voltage of 2.5V with a test current of 20mA, housed in a standard 10-DIP package measuring 0.600" (15.24mm) in width.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAN6660 is determined by the following critical parameters:

• Package Compatibility: All substitute parts must use 10-DIP (0.600", 15.24mm) packaging to ensure direct PCB footprint compatibility
• Configuration: Common anode configuration is mandatory for circuit-level compatibility
• Display Type: 7-segment single-character format required
• Electrical Operating Range: Forward voltage and test current must be compatible with existing circuit design parameters
• Physical Dimensions: Overall height, width, and depth must accommodate existing mechanical constraints

The substitute parts identified (LAP-601DB and SA56-11EWA) meet the package, configuration, and display type requirements. However, variations in color, forward voltage, current ratings, and brightness characteristics require engineering evaluation based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

LAP-601DB (Rohm Semiconductor): This substitute is active in production and ROHS3 compliant. The lower forward voltage (1.9V versus 2.5V) and reduced test current (10mA versus 20mA) result in lower power dissipation (448mW versus 600mW). The significantly higher brightness rating (250mcd versus 2.2mcd) provides enhanced visibility. Wavelength shift from 630nm to 605nm represents a minor color shift within the orange spectrum. Moisture sensitivity level increases from MSL 1 to MSL 3, requiring appropriate storage and handling protocols.

SA56-11EWA (Kingbright): This substitute is active in production and ROHS3 compliant. The primary distinction is color specification: red (627nm wavelength) versus orange (630nm). Forward voltage (2V) and test current (20mA) closely match the original specification, maintaining similar circuit operating conditions. Power dissipation is significantly lower (75mW versus 600mW). Moisture sensitivity level remains at MSL 1. This option is suitable for applications where red color output is acceptable or preferred.

Frequently Asked Questions (FAQ)

Q: Can LAP-601DB be used as a direct replacement for MAN6660 in existing circuits?

A: LAP-601DB shares identical package, configuration, and display type. However, the lower forward voltage (1.9V versus 2.5V) and reduced test current (10mA versus 20mA) require circuit verification. Existing current-limiting resistor values may need adjustment to maintain proper display brightness and segment current distribution.

Q: What is the primary difference between LAP-601DB and SA56-11EWA?

A: LAP-601DB maintains orange color output (605nm) with significantly higher brightness (250mcd). SA56-11EWA provides red color output (627nm) with lower brightness (6.4mcd) and substantially reduced power dissipation (75mW). Both share common anode configuration and 10-DIP packaging.

Q: Is SA56-11EWA suitable for applications requiring orange display output?

A: SA56-11EWA is specified as red color (627nm wavelength). While 627nm falls within the red spectrum, it does not match the orange specification (630nm) of the original MAN6660. Visual appearance will differ. Applications requiring strict orange color matching should use LAP-601DB.

Q: What are the moisture sensitivity implications of using LAP-601DB?

A: LAP-601DB carries MSL 3 rating (168 hours maximum floor life), compared to MAN6660 MSL 1 (unlimited). This requires adherence to moisture control protocols during storage, handling, and assembly. Components must be stored in dry conditions and baked according to IPC standards prior to reflow soldering if floor life is exceeded.

Q: Are all substitute parts ROHS3 compliant?

A: LAP-601DB and SA56-11EWA are both ROHS3 compliant. The original MAN6660 carries no RoHS designation due to its obsolete status. All three parts are REACH unaffected and carry EAR99 ECCN classification.

Q: Can these parts be used interchangeably in the same PCB design?

A: All three parts share identical 10-DIP (0.600", 15.24mm) package dimensions and common anode configuration, enabling mechanical and electrical interchangeability at the footprint level. However, differences in forward voltage, current ratings, brightness, and color require circuit and application-level evaluation before implementation.
