Parameter Comparison

Engineering Selection Recommendations

All three substitute parts meet the core compatibility requirements for the VLMS3101-GS08. Selection should be based on the following factors:

VLMS3100-GS08: Direct manufacturer equivalent with identical electrical specifications (2V, 10mA). Product status is active, ensuring long-term availability. Millicandela rating of 7.1mcd represents a 0.9mcd reduction from the main part. Packaging is Tape & Reel (TR), suitable for high-volume production environments.

VLMS30J1K2-GS08: Parametric equivalent with reduced forward voltage (1.8V) and test current (2mA), resulting in lower power consumption. Millicandela rating matches the main part at 8mcd. Peak wavelength of 635nm falls within acceptable range. Product status is active. Inventory availability is 799 units. This part is suitable for applications where power efficiency is a design consideration.

VLMS31J1K2-GS08: Parametric equivalent with forward voltage of 1.9V and test current of 10mA. Millicandela rating matches the main part at 8mcd. Peak wavelength of 643nm is within acceptable range. Product status is active with highest inventory availability at 15433 units. This part offers the best long-term supply security.

All substitute parts maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can VLMS3100-GS08 be used as a direct replacement for VLMS3101-GS08?

A: Yes. VLMS3100-GS08 is a direct manufacturer equivalent with identical forward voltage (2V), test current (10mA), and package specifications. The primary difference is product status: VLMS3100-GS08 is active while VLMS3101-GS08 is obsolete. Millicandela rating is slightly lower at 7.1mcd versus 8mcd.

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

A: Both are parametric equivalents with identical package and physical dimensions. VLMS30J1K2-GS08 operates at 1.8V with 2mA test current, while VLMS31J1K2-GS08 operates at 1.9V with 10mA test current. Both deliver 8mcd luminous intensity. Selection depends on circuit voltage and current requirements.

Q: Are all substitute parts available in the same packaging format?

A: VLMS3101-GS08 is supplied in standard packaging. VLMS3100-GS08, VLMS30J1K2-GS08, and VLMS31J1K2-GS08 are all supplied in Tape & Reel (TR) format, which is standard for surface mount production. All maintain identical 2-SMD, J-Lead package specifications.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant with identical Moisture Sensitivity Level (MSL) rating of 2A (4 Weeks). REACH status is unaffected for all parts. Compliance certifications are equivalent across all options.

Q: Which substitute part offers the best long-term availability?

A: VLMS31J1K2-GS08 has the highest current inventory at 15433 units, providing superior supply security. This part also maintains active product status with forward voltage of 1.9V and test current of 10mA, closely matching the original specification.

Q: Can VLMS30J1K2-GS08 be used in applications requiring 10mA test current?

A: VLMS30J1K2-GS08 is specified for 2mA test current. While the component may tolerate higher currents, operation outside specified test current parameters is not recommended for production applications. VLMS3100-GS08 or VLMS31J1K2-GS08 are preferred for 10mA applications.
