VLMO333U2AB-GS18 Orange LED 2-PLCC SMD Equivalent & Substitute Parts

Part Overview

The VLMO333U2AB-GS18 is an orange 605nm LED indication component manufactured by Vishay Semiconductor Opto Division. This surface mount device operates at 2.1V forward voltage with a 950mcd brightness rating and is housed in a 2-SMD, J-Lead package. The component is Active status and ROHS3 compliant, making it suitable for current production applications. Substitute parts may be required due to inventory constraints, supply chain discontinuities, or design optimization needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLMO333U2AB-GS18 are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Color: Orange
• Wavelength - Dominant: 605nm
• Mounting Type: Surface Mount
• Package / Case: 2-PLCC or 2-SMD, J-Lead
• Viewing Angle: 120°
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variations:

• Voltage - Forward (Vf): 1.9V to 2.1V (within typical LED tolerance)
• Millicandela Rating: 220mcd to 950mcd (brightness variation acceptable for indication applications)
• Physical dimensions: Minor variations within 2-PLCC package specification
• Lens transparency: Clear or standard (does not affect core function)

The VLMO333U2AB-GS08 is a parametric equivalent from the same manufacturer and series, differing only in tape reel configuration. The HSML-A101-S00J1 from Broadcom Limited is a manufacturer-recommended substitute offering cross-platform compatibility with slightly lower forward voltage and brightness characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three components maintain Active product status and ROHS3 compliance, ensuring regulatory alignment for current production environments.

VLMO333U2AB-GS08: This part is functionally identical to the VLMO333U2AB-GS18, differing only in tape reel configuration (GS08 vs. GS18). Selection between these two Vishay components depends solely on packaging and supply chain requirements. Both deliver 950mcd brightness at 2.1V forward voltage.

HSML-A101-S00J1: This Broadcom component provides cross-manufacturer substitution with the following electrical differences: 1.9V forward voltage (0.2V lower) and 220mcd brightness (730mcd lower). The physical footprint is slightly larger (3.20mm L vs. 3.00mm L, 2.10mm H vs. 1.85mm H). This substitute is suitable for applications where brightness reduction is acceptable and circuit design accommodates the lower forward voltage. The 2-PLCC package maintains surface mount compatibility.

Frequently Asked Questions (FAQ)

Q: Can VLMO333U2AB-GS08 be used as a direct replacement for VLMO333U2AB-GS18?

A: Yes. Both parts are electrically and mechanically identical. The suffix difference (GS08 vs. GS18) indicates tape reel configuration only. Selection depends on procurement and assembly line requirements.

Q: What are the key differences between Vishay and Broadcom substitutes?

A: The HSML-A101-S00J1 operates at 1.9V forward voltage compared to 2.1V for Vishay parts, and provides 220mcd brightness versus 950mcd. Physical dimensions are slightly larger. These differences require circuit design verification before substitution.

Q: Is the HSML-A101-S00J1 suitable for high-brightness indication applications?

A: The HSML-A101-S00J1 delivers 220mcd, which is significantly lower than the 950mcd of the VLMO333U2AB-GS18. Application suitability depends on specific brightness requirements. Designs requiring the full 950mcd output should use the Vishay component.

Q: Are all three parts compatible with the same PCB footprint?

A: The Vishay parts (VLMO333U2AB-GS18 and VLMO333U2AB-GS08) share identical footprints at 3.00mm L x 2.80mm W. The Broadcom HSML-A101-S00J1 has a slightly larger footprint (3.20mm L x 2.80mm W) and greater height (2.10mm vs. 1.85mm). PCB layout verification is required before substitution.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three components are ROHS3 compliant and maintain Active product status, ensuring regulatory alignment for current production applications.
