LA-601ML Green 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The LA-601ML is a single-character green 7-segment LED display manufactured by Rohm Semiconductor, packaged in a 10-DIP configuration. This component is classified as an active product and is designed for numeric and alphanumeric display applications requiring common cathode operation. The LA-601ML remains in active production status. Substitute parts may be required due to inventory constraints, lead time considerations, or specific application requirements related to electrical performance parameters such as forward voltage, current consumption, or brightness characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the LA-601ML is determined by the following critical parameters:

• Display Configuration: Single-character 7-segment format with common cathode topology
• Package Type: 10-DIP pinout compatibility
• Color Specification: Green wavelength (560-570nm range)
• Electrical Operating Range: Forward voltage tolerance and current handling capability
• Regulatory Compliance: RoHS3 and REACH compliance status

The TDSG5160 (Vishay Semiconductor Opto Division) qualifies as a substitute based on matching display type, character count, common cathode configuration, color specification, and 10-DIP packaging. Both parts maintain identical regulatory compliance certifications and moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the LA-601ML and TDSG5160 maintain active product status and full RoHS3 compliance, qualifying them for equivalent use in applications where regulatory requirements are a primary selection criterion. The LA-601ML operates at lower forward voltage (2.1V vs. 2.4V) and lower test current (10mA vs. 20mA), resulting in reduced power dissipation. The LA-601ML also provides higher brightness output (22mcd vs. 9.5mcd) at the specified test current. The TDSG5160 features a larger physical package footprint (0.600" DIP spacing vs. 0.400" DIP spacing) and higher maximum power dissipation rating. Selection between these parts should be based on circuit design requirements for voltage supply, current budget, brightness requirements, and PCB layout constraints related to DIP pin spacing.

Frequently Asked Questions (FAQ)

Q: Can the TDSG5160 directly replace the LA-601ML in existing designs?

A: Both parts share identical display type (7-segment), character count (1), common cathode configuration, color (green), and 10-DIP package classification. However, the DIP pin spacing differs (0.400" vs. 0.600"), requiring PCB layout verification. Forward voltage and current specifications differ, necessitating circuit design review to confirm compatibility with existing current-limiting resistor values and power supply specifications.

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

A: The LA-601ML operates at 2.1V forward voltage with 10mA test current and 22mcd brightness. The TDSG5160 operates at 2.4V forward voltage with 20mA test current and 9.5mcd brightness. These differences affect circuit design, particularly resistor selection and power supply requirements.

Q: Are both parts compliant with environmental regulations?

A: Both the LA-601ML and TDSG5160 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and use.

Q: What physical dimension differences exist between these displays?

A: The LA-601ML digit size is 0.58" (14.60mm) with overall dimensions of 0.748" H x 0.492" W x 0.315" D. The TDSG5160 digit size is 0.51" (13.00mm) with overall dimensions of 0.689" H x 0.482" W x 0.252" D. The DIP package pin spacing also differs (0.400" vs. 0.600"), affecting PCB footprint compatibility.

Q: Which part should be selected for brightness-critical applications?

A: The LA-601ML provides 22mcd brightness compared to the TDSG5160's 9.5mcd at their respective test currents, making the LA-601ML suitable for applications requiring higher luminous intensity.
