VLMS2100-GS08 Equivalent & Substitute Parts

Part Overview

The VLMS2100-GS08 is a red MiniLED surface mount indicator from Vishay Semiconductor Opto Division, designed for discrete LED indication applications. This component features a 628nm dominant wavelength with 7.1mcd brightness rating and operates at 2.1V forward voltage. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing production and maintenance applications. Equivalent parts must maintain compatibility with the 2-SMD J-Lead package format and preserve the optical and electrical characteristics required for reliable circuit operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLMS2100-GS08 is determined by strict adherence to the following critical parameters:

Package Compatibility: The substitute must use the 2-SMD J-Lead package format with identical physical dimensions (2.20mm L x 1.40mm W, 1.40mm max height) to ensure PCB footprint compatibility.

Optical Characteristics: Red color specification and rectangular flat-top lens style with 1.50mm x 0.90mm lens size must be maintained. Wavelength range (dominant wavelength 628-630nm, peak wavelength 640-643nm) defines the red spectrum compatibility zone.

Electrical Parameters: Forward voltage (Vf) and test current specifications determine circuit compatibility. Substitutes operating at different voltage or current ratings require circuit redesign.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are mandatory for equivalent parts in regulated applications.

Availability Status: Active product status is preferred for long-term supply assurance, particularly given the obsolete status of the original component.

The VLMS20H2L1-GS08 qualifies as a direct substitute based on matching package format, optical configuration, lens specifications, and regulatory compliance across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The VLMS20H2L1-GS08 is the designated substitute for the obsolete VLMS2100-GS08. Both components maintain identical package geometry, lens configuration, and regulatory compliance status (ROHS3 and REACH unaffected). The substitute is currently in active production status, ensuring supply chain continuity.

Circuit designers must account for electrical parameter differences: the substitute operates at 1.8V forward voltage versus 2.1V for the original part, and at 2mA test current versus 10mA. These differences require verification of current-limiting resistor values and voltage supply compatibility within the target application. The substitute delivers higher brightness (9mcd versus 7.1mcd), which may necessitate adjustment of series resistor values to maintain consistent indicator brightness in the application.

Optical characteristics remain compatible within the red spectrum range, with dominant wavelengths of 628nm and 630nm respectively, supporting equivalent visual appearance in indication applications.

Frequently Asked Questions (FAQ)

Q: Can the VLMS20H2L1-GS08 be used as a direct drop-in replacement for the VLMS2100-GS08?

A: Physical and package compatibility is confirmed. However, electrical parameter differences require circuit verification. The substitute operates at lower forward voltage (1.8V vs 2.1V) and lower test current (2mA vs 10mA), necessitating resistor value recalculation to maintain proper circuit operation.

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

A: Primary differences are product status (obsolete vs. active), forward voltage (2.1V vs. 1.8V), test current (10mA vs. 2mA), and brightness rating (7.1mcd vs. 9mcd). Optical and package specifications remain identical.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the VLMS2100-GS08 and VLMS20H2L1-GS08 are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for controlled markets.

Q: Does the higher brightness of the substitute affect compatibility?

A: The substitute's higher brightness (9mcd vs. 7.1mcd) is optically compatible but may appear brighter in the application. Series resistor adjustment is required to match the original brightness level if visual consistency is critical.

Q: What is the moisture sensitivity level for both parts?

A: Both components are rated MSL 2A (4 Weeks), requiring identical handling and storage protocols during manufacturing and assembly.
