Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLMS30J1L2-GS18 are qualified based on the following criteria:

Mechanical Compatibility: All substitute parts maintain identical package type (2-SMD, J-Lead), 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). This ensures direct PCB footprint compatibility without layout modifications.

Optical Characteristics: Substitute parts are limited to red LEDs with dominant wavelength in the 630nm range (630nm or 648nm) and peak wavelengths between 635nm and 650nm. This maintains color consistency and visual performance in indication applications.

Electrical Parameters: Forward voltage (Vf) is constrained to 1.8V or 1.9V typical values. Test current ranges from 2mA to 10mA. Millicandela ratings vary from 11mcd to 13.2mcd, representing acceptable brightness variations within the red LED indication category.

Regulatory Compliance: All substitute parts are Active status, ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (2A, 4 Weeks), ensuring compliance equivalence.

Series Designation: Substitute parts belong to the VLM.3 or VLM3 series, maintaining manufacturer product line consistency.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory equivalence with the VLMS30J1L2-GS18. Selection among substitute options is determined by specific electrical and optical requirements:

VLMS30J1L2-GS08: Identical electrical and optical specifications to the main part (630nm dominant wavelength, 1.8V Vf, 2mA test current, 11mcd). Differs only in packaging designation (GS08 vs. GS18). This part provides direct functional equivalence with highest inventory availability (5900 pcs).

VLMS30K1L2-GS08: Maintains 630nm wavelength and 1.8V forward voltage but provides increased brightness at 13mcd versus 11mcd. Test current remains 2mA. Selection appropriate when higher luminous intensity is required within the same voltage class.

VLMD3100-GS08: Operates at 1.8V forward voltage with 10mA test current, representing higher current operation. Dominant wavelength shifts to 648nm with peak at 650nm, producing a slightly deeper red appearance. Selection appropriate for applications requiring higher current drive capability.

VLMS31J1L2-GS08: Forward voltage increases to 1.9V with 10mA test current. Maintains 630nm dominant wavelength and 11mcd brightness. Selection appropriate for circuits designed for 1.9V operation or when higher current drive is required.

VLMS31K1L2-GS08: Combines 1.9V forward voltage, 10mA test current, and increased brightness at 13mcd. Selection appropriate for high-current, high-brightness applications within the 1.9V voltage class.

Frequently Asked Questions (FAQ)

Q: Can VLMS30K1L2-GS08 replace VLMS30J1L2-GS18 in existing designs?

A: Yes, from a mechanical and package perspective. The primary difference is increased millicandela rating (13mcd vs. 11mcd). Circuit design must accommodate the higher brightness output. Forward voltage (1.8V) and test current (2mA) remain identical, so existing current-limiting resistor values are compatible.

Q: What is the difference between GS08 and GS18 packaging designations?

A: Both designations refer to Tape & Reel (TR) packaging. VLMS30J1L2-GS08 and VLMS30J1L2-GS18 are electrically and optically identical. The designation difference reflects packaging configuration or supplier variation. Both are suitable for automated assembly.

Q: Can parts with 1.9V forward voltage (VLMS31 series) substitute for 1.8V parts (VLMS30 series)?

A: Mechanical and optical compatibility is maintained. However, circuit design must accommodate the 0.1V forward voltage increase. Existing current-limiting resistor calculations require adjustment to maintain proper LED current. Direct substitution without circuit modification may result in incorrect brightness or reduced LED lifespan.

Q: How does the 648nm wavelength of VLMD3100-GS08 compare to the 630nm of the main part?

A: Both are red LEDs within acceptable indication ranges. The 648nm wavelength produces a slightly deeper red appearance compared to 630nm. Visual perception difference is minimal in most indication applications. Optical filter compatibility should be verified if color-critical applications are involved.

Q: Are all substitute parts suitable for automated pick-and-place assembly?

A: Yes. All substitute parts use identical 2-SMD J-Lead package configuration with matching physical dimensions (3.00mm L x 2.80mm W, 1.85mm max height). PCB footprints are directly compatible without modification. Tape & Reel packaging supports standard SMT assembly equipment.

Q: What is the moisture sensitivity implication for storage and handling?

A: All parts carry MSL 2A rating (4 Weeks), indicating moisture sensitivity level 2 with 4-week floor life after bag opening. Storage in dry conditions (below 30% relative humidity) is required. Parts exposed to ambient conditions beyond 4 weeks require baking per IPC-A-2.1 specifications before reflow soldering.
