Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLMS30J1K2-GS18 is determined by the following critical parameters:

Mechanical Compatibility: Package type (2-SMD, J-Lead / 2-PLCC), physical dimensions (3.00mm L x 2.80mm W, 1.85mm max height), lens style (round with flat top), and lens size (2.40mm diameter) must remain identical to ensure PCB footprint compatibility and optical performance consistency.

Optical Characteristics: Color (red), dominant wavelength (630nm), and viewing angle (120°) define the functional optical output and must be maintained for circuit operation.

Electrical Parameters: Forward voltage (Vf), test current, and millicandela rating determine circuit compatibility and brightness performance. Variations in these parameters affect circuit design and application suitability.

Compliance & Status: RoHS3 compliance and MSL rating ensure regulatory adherence and handling requirements are met. Active product status ensures ongoing availability and supply chain reliability.

The identified substitutes maintain these critical parameters while offering active product status and improved supply availability compared to the obsolete VLMS30J1K2-GS18.

Parameter Comparison

Engineering Selection Recommendations

VLMS30J1K2-GS08 provides direct electrical and optical equivalence to the obsolete VLMS30J1K2-GS18. Both components operate at 1.8V forward voltage with 2mA test current and deliver identical 8mcd brightness at 630nm dominant wavelength. This substitute maintains full mechanical and electrical compatibility with existing circuit designs. The component carries active product status with ROHS3 compliance and standard MSL 2A rating. Tape & Reel packaging supports automated assembly processes.

VLMS31J1K2-GS08 offers functional substitution with design considerations. While maintaining identical mechanical form factor, optical wavelength, and viewing angle, this component operates at 1.9V forward voltage with 10mA test current. The higher test current and forward voltage require circuit evaluation to confirm compatibility with existing current-limiting resistor networks and power supply specifications. Peak wavelength shifts to 643nm, representing a minor spectral variation within the red LED spectrum. Active product status and ROHS3 compliance are maintained. Significantly higher inventory availability (15433 pcs) supports supply chain continuity.

Both substitutes are manufactured by Vishay Semiconductor Opto Division and maintain identical physical dimensions, package configuration, and compliance certifications as the original component.

Frequently Asked Questions (FAQ)

Q: Can VLMS30J1K2-GS08 be used as a direct replacement for VLMS30J1K2-GS18?

A: Yes. Both components share identical electrical parameters (1.8V Vf, 2mA test current), optical characteristics (630nm dominant wavelength, 8mcd), mechanical dimensions (3.00mm L x 2.80mm W, 1.85mm height), and package configuration (2-PLCC, J-Lead). PCB footprint and circuit operation remain unchanged.

Q: What are the key differences between VLMS30J1K2-GS08 and VLMS31J1K2-GS08?

A: The primary differences are forward voltage (1.8V vs 1.9V), test current (2mA vs 10mA), and peak wavelength (635nm vs 643nm). Both maintain 630nm dominant wavelength, 8mcd brightness, and identical mechanical form factors. Circuit compatibility depends on current-limiting resistor design and power supply specifications.

Q: Does packaging format affect electrical or optical performance?

A: No. The VLMS30J1K2-GS18 bulk packaging and VLMS30J1K2-GS08 / VLMS31J1K2-GS08 Tape & Reel packaging contain identical components. Packaging format affects supply chain logistics and automated assembly compatibility only.

Q: Are all three components RoHS3 compliant?

A: Yes. VLMS30J1K2-GS18, VLMS30J1K2-GS08, and VLMS31J1K2-GS08 all carry ROHS3 compliance certification and MSL 2A (4 Weeks) moisture sensitivity rating.

Q: Which substitute offers better supply availability?

A: VLMS31J1K2-GS08 provides significantly higher inventory (15433 pcs) compared to VLMS30J1K2-GS08 (799 pcs). Selection depends on circuit compatibility with the 1.9V forward voltage and 10mA test current specifications.
