MAN6730 Equivalent & Substitute Parts Reference

Part Overview

The MAN6730 is a 7-segment LED display module manufactured by onsemi, featuring a 1.5-character red display with 0.56" digit height in an 18-DIP package configuration. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The display operates as a common anode configuration with a maximum forward voltage of 2V and test current of 20mA, suitable for numeric and alphanumeric display applications in industrial and consumer electronics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAN6730 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Display Type: 7-Segment LED configuration
• Common Pin Configuration: Common Anode
• Color: Red
• Package Type: DIP format with compatible pinout
• Voltage Range: Forward voltage compatibility within operational limits
• Current Rating: Test current capacity of 20mA or greater

Substitution Logic: The LTD-6730P represents a direct form-fit-function substitute, matching the 1.5-character configuration, 0.56" digit height, 18-DIP package, and common anode topology. The LDS-A504RI functions as a partial substitute for applications where single-character display is acceptable, offering common anode configuration and compatible DIP packaging, though with reduced character count and digit height.

Parameter Comparison

Engineering Selection Recommendations

LTD-6730P (Primary Substitute): The LTD-6730P is the recommended substitute for direct replacement applications. It maintains identical character count (1.5), digit height (0.56"), package configuration (18-DIP), and common anode topology. The component is currently in active production status with ROHS3 compliance certification. Forward voltage specification of 2.1V represents a marginal increase from the MAN6730's 2V maximum, requiring circuit verification for voltage-sensitive applications. Both components share identical test current (20mA) and moisture sensitivity ratings.

LDS-A504RI (Conditional Substitute): The LDS-A504RI is suitable only for applications where single-character display functionality is acceptable. This substitute offers active product status and compatible common anode configuration with DIP packaging. The reduced digit height (0.50" versus 0.56") and single-character limitation restrict its use to applications with modified display requirements. Test current is reduced to 10mA, resulting in lower power dissipation (105mW versus 840mW for the main part).

Frequently Asked Questions (FAQ)

Q: Can the LTD-6730P be used as a direct replacement for the MAN6730 without circuit modification?

A: The LTD-6730P is mechanically and electrically compatible for direct substitution in most applications. The forward voltage increase from 2V to 2.1V is within typical design margins for LED display circuits. Verify that your current-limiting resistor network accommodates the 2.1V specification. Pin configuration and package footprint are identical.

Q: What are the key differences between the LTD-6730P and LDS-A504RI substitutes?

A: The LTD-6730P maintains the 1.5-character, 0.56" digit height configuration in an 18-DIP package, providing form-fit-function equivalence. The LDS-A504RI reduces to single-character display with 0.50" digit height in a 10-DIP package, requiring circuit redesign and PCB layout modification. Character count and digit height differences make these substitutes suitable for different application categories.

Q: Are there pinout compatibility concerns when substituting these parts?

A: The LTD-6730P uses an 18-DIP package with identical pinout to the MAN6730. The LDS-A504RI uses a 10-DIP package with different pinout, requiring complete circuit redesign and PCB layout changes. Verify pinout documentation before implementing the LDS-A504RI in existing designs.

Q: What compliance certifications apply to these substitute parts?

A: The LTD-6730P carries ROHS3 compliance certification. All three components (MAN6730, LTD-6730P, and LDS-A504RI) are REACH Unaffected and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements.

Q: How do the electrical specifications compare for circuit design purposes?

A: Forward voltage ranges from 2V (MAN6730, LDS-A504RI) to 2.1V (LTD-6730P). Test current is 20mA for MAN6730 and LTD-6730P, reduced to 10mA for LDS-A504RI. Power dissipation varies significantly: 840mW (MAN6730), 40mW (LTD-6730P), and 105mW (LDS-A504RI). These differences reflect different LED brightness ratings and must be considered in thermal and power budget calculations.
