VLME3100-GS18 Yellow LED 2-PLCC SMD Equivalent & Substitute Parts

Part Overview

The VLME3100-GS18 is a yellow 588nm LED indicator in a 2-SMD, J-Lead surface mount package manufactured by Vishay Semiconductor Opto Division. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing production and maintenance applications. The part delivers 45 millicandela at 10mA forward current with a 2V typical forward voltage and 120° viewing angle. Due to its obsolete status, sourcing alternatives from the same product family is necessary to maintain design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLME3100-GS18 is determined by strict equivalence across the following critical parameters:

• Color and wavelength specifications (Yellow, 588nm dominant, 590nm peak)
• Optical output (45mcd at 10mA test current)
• Electrical characteristics (2V forward voltage, 10mA test current)
• Mechanical form factor (2-SMD, J-Lead package; 2-PLCC supplier package; 3.00mm L x 2.80mm W; 1.85mm max height)
• Viewing angle (120°)
• Lens configuration (Round with Flat Top, 2.40mm diameter, Clear)
• Compliance certifications (ROHS3, REACH Unaffected)

The VLME3100-GS08 qualifies as a parametric equivalent substitute because it maintains identical electrical, optical, and mechanical specifications across all these parameters. The primary distinction is packaging format: VLME3100-GS18 is supplied in cut tape, while VLME3100-GS08 is supplied in tape and reel (TR) format. Both parts belong to the VLM3 series and share the same base product number VLME3100.

Parameter Comparison

Engineering Selection Recommendations

The VLME3100-GS08 is the direct parametric equivalent for the obsolete VLME3100-GS18. Selection of VLME3100-GS08 is supported by:

• Active product status, ensuring continued availability and supply chain stability
• Complete electrical and optical parameter equivalence across all specified characteristics
• Identical mechanical form factor and PCB footprint compatibility
• Matching compliance certifications (ROHS3 Compliant, REACH Unaffected)
• Identical moisture sensitivity level (2A, 4 Weeks) and handling requirements

The only operational difference is packaging format. VLME3100-GS08 is supplied in tape and reel format, which is standard for production environments and offers advantages in automated assembly processes. If cut tape format is required for specific assembly workflows, tape and reel stock can be converted to cut tape through standard component preparation processes.

Frequently Asked Questions (FAQ)

Q: Can VLME3100-GS08 be used as a direct replacement for VLME3100-GS18 on existing PCBs?

A: Yes. Both parts share identical electrical specifications (2V forward voltage, 10mA test current), optical output (45mcd, 588nm dominant wavelength), and mechanical dimensions (3.00mm L x 2.80mm W, 1.85mm max height). PCB footprints and solder pad layouts are compatible.

Q: What is the difference between the two part numbers?

A: The primary difference is packaging format. VLME3100-GS18 is supplied in cut tape, while VLME3100-GS08 is supplied in tape and reel (TR) format. All component specifications are identical.

Q: Is VLME3100-GS08 suitable for high-volume production?

A: Yes. VLME3100-GS08 has active product status with 7900 pieces in stock and is supplied in tape and reel format, which is optimized for automated pick-and-place assembly processes.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and share identical moisture sensitivity levels (2A, 4 Weeks).

Q: What viewing angle does this LED provide?

A: Both VLME3100-GS18 and VLME3100-GS08 provide a 120° viewing angle with a round flat-top lens configuration.

Q: Can I mix VLME3100-GS18 and VLME3100-GS08 in the same production batch?

A: Yes. Since all electrical, optical, and mechanical parameters are identical, both parts can be used interchangeably in the same design and assembly process.
