Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLMS30J1K2-GS08 is determined by the following critical parameters:

Mechanical Compatibility: Package type (2-SMD J-Lead), mounting type (Surface Mount), physical dimensions (3.00mm L x 2.80mm W, 1.85mm max height), and lens configuration (Round with Flat Top, 2.40mm diameter) must remain identical.

Optical Compatibility: Color (Red), dominant wavelength (630nm), and millicandela rating (8mcd) establish the functional light output characteristics.

Electrical Compatibility: Forward voltage (Vf) and test current parameters define circuit integration requirements. Variations within the specified tolerance range of the original design are permissible.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are mandatory for substitute parts.

The VLMS31J1K2-GS08 qualifies as a parametric equivalent based on matching mechanical, optical, and regulatory requirements while operating within acceptable electrical parameter ranges for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both VLMS30J1K2-GS08 and VLMS31J1K2-GS08 maintain Active product status with identical RoHS3 compliance and REACH unaffected designation. Selection between these parts is based on electrical parameter requirements and inventory availability. The VLMS30J1K2-GS08 operates at 1.8V typical forward voltage with 2mA test current, while the VLMS31J1K2-GS08 operates at 1.9V typical forward voltage with 10mA test current. Both components share identical mechanical packaging, optical characteristics (8mcd, 630nm dominant wavelength), and regulatory compliance status. Circuit design parameters determine which electrical specification aligns with system requirements.

Frequently Asked Questions (FAQ)

Q: Can VLMS31J1K2-GS08 directly replace VLMS30J1K2-GS08 in existing designs?

A: Direct replacement is possible when circuit design accommodates the electrical parameter differences. The VLMS31J1K2-GS08 operates at 1.9V forward voltage versus 1.8V for the VLMS30J1K2-GS08, and at 10mA test current versus 2mA. Mechanical compatibility is confirmed; however, power supply and current-limiting resistor values must be evaluated for the specific application.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components share identical mechanical specifications: 3.00mm length, 2.80mm width, 1.85mm maximum height, 2-SMD J-Lead package, and 2.40mm diameter round flat-top lens.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both VLMS30J1K2-GS08 and VLMS31J1K2-GS08 are RoHS3 compliant, REACH unaffected, and carry identical MSL 2A (4 Weeks) ratings.

Q: What is the primary difference between these substitute parts?

A: The primary differences are forward voltage (1.8V versus 1.9V) and test current (2mA versus 10mA). Optical output (8mcd at 630nm dominant wavelength) and mechanical packaging remain identical.

Q: Are there wavelength differences between these parts?

A: Both parts specify 630nm as the dominant wavelength. Peak wavelength differs slightly: 635nm for VLMS30J1K2-GS08 and 643nm for VLMS31J1K2-GS08. This variation remains within the red LED spectrum classification.
