Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLMO333U2AB-GS08 are classified based on the following critical parameters that determine functional equivalence:

Parametric Equivalent Classification: Parts sharing identical electrical characteristics (wavelength, forward voltage, test current, brightness, viewing angle) and compatible mechanical form factors (package type, mounting method, dimensions, height).

Manufacturer Recommended Classification: Parts meeting the same functional requirements with allowable variations in specific parameters while maintaining overall system compatibility.

The VLMO333U2AB-GS08 accepts substitutes that maintain:

• Orange color specification (605nm dominant wavelength range)
• 2-PLCC package compatibility for surface mount assembly
• 120° viewing angle for indicator applications
• Forward voltage within acceptable circuit design tolerance
• Brightness suitable for indication purposes

Parameter Comparison

Engineering Selection Recommendations

VLMO333U2AB-GS18 (Parametric Equivalent): This part is functionally identical to the VLMO333U2AB-GS08 across all critical electrical and mechanical parameters. Both parts are manufactured by Vishay Semiconductor Opto Division within the same VLMK.333 series. Selection between these two variants is based on packaging tape reel specifications (GS08 vs GS18 designations) and inventory availability. Both maintain Active product status and ROHS3 compliance.

HSML-A101-S00J1 (Manufacturer Recommended): This Broadcom Limited part provides functional substitution with the following considerations: forward voltage is 0.2V lower (1.9V vs 2.1V), brightness is reduced to 220mcd from 950mcd, lens size is slightly smaller (2.20mm vs 2.40mm diameter), and overall height is increased to 2.10mm. The part maintains 605nm dominant wavelength, 120° viewing angle, 2-PLCC package compatibility, and surface mount assembly method. This substitute is suitable for applications where the lower brightness and reduced forward voltage are acceptable within circuit design parameters. All three parts maintain ROHS3 compliance and equivalent MSL ratings.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically identical. The GS08 and GS18 designations refer to tape reel packaging specifications. Selection depends on assembly equipment compatibility and tape reel configuration requirements.

Q: What are the key differences when substituting HSML-A101-S00J1 for VLMO333U2AB-GS08?

A: The HSML-A101-S00J1 operates at 1.9V forward voltage compared to 2.1V, reducing circuit current draw by approximately 9%. Brightness is significantly lower at 220mcd versus 950mcd. Physical dimensions vary slightly: lens diameter is 2.20mm versus 2.40mm, and maximum height is 2.10mm versus 1.85mm. These differences require circuit design verification to ensure adequate brightness for the intended indication application.

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

A: The VLMO333U2AB-GS08 and VLMO333U2AB-GS18 share identical footprints (3.00mm L x 2.80mm W, 1.85mm height). The HSML-A101-S00J1 has slightly different dimensions (3.20mm L x 2.80mm W, 2.10mm height) and may require PCB layout verification for clearance and solder joint integrity.

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

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry equivalent MSL ratings of 2A (4 Weeks). All parts are classified as Active products.

Q: What is the primary reason to select HSML-A101-S00J1 over the Vishay alternatives?

A: The HSML-A101-S00J1 provides significantly higher inventory availability (37,838 pcs vs 1,201 and 8,218 pcs respectively) and is manufactured by Broadcom Limited. Selection is based on supply chain requirements and circuit design tolerance for the reduced brightness and forward voltage characteristics.
