Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with current manufacturing standards. Selection among equivalent components depends on specific circuit requirements:

VLMD3100-GS08 operates at 1.8V forward voltage with 648nm dominant wavelength, offering higher luminous intensity (11.2mcd) at reduced voltage. This component suits applications requiring lower power consumption or where forward voltage headroom is constrained.

VLMS30J1L2-GS08 operates at 1.8V forward voltage with 2mA test current, providing the lowest power consumption profile. This component is appropriate for battery-powered or low-current indication circuits where luminous intensity requirements are less stringent (11mcd available).

VLMS31J1L2-GS08 maintains identical electrical characteristics to the primary part (1.9V, 10mA, 630nm) with equivalent 11mcd luminous intensity, offering direct functional replacement with identical forward voltage and test current specifications.

All substitute components share identical mechanical packaging, PCB footprint, and environmental compliance ratings, permitting direct substitution without circuit redesign or layout modification.

Frequently Asked Questions (FAQ)

Q: Can VLMD3100-GS08 replace VLMS31J2L1-GS08 in existing designs?

A: Yes. VLMD3100-GS08 maintains identical mechanical form factor, package type, and mounting characteristics. The 1.8V forward voltage (versus 1.9V) and 648nm wavelength (versus 630nm) represent allowable variations within red LED specification ranges. Circuit current-limiting resistor values may require adjustment to account for the 0.1V voltage difference.

Q: What is the primary difference between VLMS30J1L2-GS08 and VLMS31J2L1-GS08?

A: VLMS30J1L2-GS08 operates at 2mA test current compared to 10mA for VLMS31J2L1-GS08. This lower current rating makes VLMS30J1L2-GS08 suitable for low-power applications. Both components share identical 1.8V forward voltage and 630nm wavelength specifications. Circuit design must accommodate the reduced current requirement.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All listed substitute components are supplied in Tape & Reel (TR) packaging format, maintaining compatibility with automated assembly processes and standard component handling procedures.

Q: Do substitute parts require different PCB footprints?

A: No. All substitute components utilize identical 2-SMD, J-Lead package geometry with 3.00mm L x 2.80mm W dimensions and 1.85mm maximum height. Direct PCB footprint compatibility is maintained across all listed parts.

Q: What is the moisture sensitivity consideration for these components?

A: All components carry MSL 2A (4 Weeks) rating, indicating identical moisture sensitivity levels. Storage and handling procedures remain consistent across the primary part and all substitutes.
