TDSG5160-MN 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The TDSG5160-MN is a single-character green 7-segment LED display manufactured by Vishay Semiconductor Opto Division. This common cathode display operates at 2.4V forward voltage with a 20mA test current and delivers 14mcd brightness at a 0.51" character size. The component is housed in a 10-DIP package and maintains Active product status with full RoHS3 compliance.

Equivalent and substitute parts become necessary when addressing supply chain constraints, inventory availability, or specific application requirements that may benefit from alternative electrical or mechanical characteristics within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TDSG5160-MN is determined by the following critical parameters:

Primary Compatibility Criteria:

• Display Type: 7-Segment (required)
• Number of Characters: 1 (required)
• Common Pin Configuration: Common Cathode (required)
• Color: Green (required)
• Package / Case: 10-DIP (required)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) Typical: 1.9V to 2.4V range
• Current - Test: 10mA to 20mA range
• Millicandela Rating: 14mcd minimum
• Wavelength - Peak: 563nm to 572nm range
• Physical Dimensions: Mechanical fit within standard 10-DIP footprint

The substitute parts LA-601ML and LAP-601ML from Rohm Semiconductor satisfy all primary compatibility criteria and operate within acceptable secondary parameter ranges for direct substitution in common cathode 7-segment display applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and RoHS3 compliance, confirming suitability for current design and manufacturing environments.

TDSG5160-MN (Primary Part): Baseline specification with 14mcd brightness and 2.4V forward voltage. Moisture Sensitivity Level 1 provides unlimited shelf life without special storage requirements.

LA-601ML (Rohm Substitute): Operates at reduced forward voltage (2.1V) and test current (10mA), resulting in lower power dissipation (60mW). Brightness increases to 22mcd. Moisture Sensitivity Level 1 matches the primary part. Package pitch differs (0.400" vs. 0.600"), requiring PCB layout verification.

LAP-601ML (Rohm Substitute): Delivers highest brightness at 100mcd with lowest forward voltage (1.9V) and reduced test current (10mA). Power dissipation reaches 448mW. Moisture Sensitivity Level 3 requires controlled storage conditions (168-hour limit at specified humidity). Package pitch matches the primary part (0.600").

Selection between substitutes depends on brightness requirements, power budget constraints, and storage environment capabilities.

Frequently Asked Questions (FAQ)

Q: Can LA-601ML and LAP-601ML be used interchangeably with TDSG5160-MN?

A: Both Rohm parts are functionally equivalent as common cathode 7-segment green displays in 10-DIP packages. Direct substitution is possible with circuit design consideration for voltage and current differences. LA-601ML uses a 0.400" DIP pitch while LAP-601ML uses 0.600" pitch matching the original part.

Q: What are the key electrical differences between these parts?

A: Forward voltage ranges from 1.9V (LAP-601ML) to 2.4V (TDSG5160-MN). Test current is 20mA for TDSG5160-MN and 10mA for both Rohm parts. Brightness varies from 14mcd (TDSG5160-MN) to 100mcd (LAP-601ML). These differences affect circuit design for current-limiting resistors and power supply requirements.

Q: Are there mechanical compatibility concerns?

A: LA-601ML uses a 0.400" DIP pitch versus the standard 0.600" pitch of TDSG5160-MN and LAP-601ML. Physical dimensions also differ slightly. PCB footprint verification is required before selecting LA-601ML. LAP-601ML maintains identical package pitch and similar dimensions to the primary part.

Q: What is the impact of Moisture Sensitivity Level differences?

A: TDSG5160-MN and LA-601ML carry MSL 1 (Unlimited shelf life). LAP-601ML carries MSL 3, requiring storage at controlled humidity with a 168-hour floor life limit after moisture exposure. This affects inventory management and component handling procedures.

Q: Which substitute offers the best brightness performance?

A: LAP-601ML provides 100mcd brightness compared to 14mcd for TDSG5160-MN and 22mcd for LA-601ML. Selection depends on application visibility requirements and whether increased brightness justifies the MSL 3 storage constraints.

Q: Are all parts RoHS3 compliant?

A: Yes. TDSG5160-MN, LA-601ML, and LAP-601ML all maintain RoHS3 compliance and REACH Unaffected status, confirming suitability for regulated manufacturing environments.
