Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLMK333U2AB-GS08 is determined by the following criteria:

Mandatory Compatibility Parameters:

• Color: Amber
• Mounting Type: Surface Mount
• Package / Case: 2-PLCC (compatible with 2-SMD, J-Lead footprint)
• Viewing Angle: 120°
• Current - Test: 20mA
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 2A (4 Weeks)

Allowable Variation Parameters:

• Voltage - Forward (Vf): ±0.3V tolerance acceptable for discrete indication applications
• Wavelength - Dominant: Amber spectrum range (590nm–622nm)
• Millicandela Rating: Variation permitted based on application brightness requirements
• Physical dimensions: Minor variations acceptable within standard PCB footprint tolerances

The three identified substitute parts (HSMA-A100-R40J1, HSMU-A100-R00J1, HSMU-A100-S00J1) from Broadcom Limited meet all mandatory compatibility parameters and maintain functional equivalence within the specified allowable variations.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and full RoHS3 compliance with REACH unaffected designation, matching the regulatory profile of the VLMK333U2AB-GS08.

HSMA-A100-R40J1 operates at 1.9V forward voltage, representing a 0.2V reduction from the main part. This part is suitable for applications where lower power consumption is acceptable and brightness requirements do not mandate the 850mcd rating of the original component.

HSMU-A100-R00J1 and HSMU-A100-S00J1 both operate at 2.2V forward voltage with 320mcd brightness rating. These parts differ primarily in packaging format: HSMU-A100-R00J1 is supplied in Cut Tape (CT) & Digi-Reel® format, while HSMU-A100-S00J1 is supplied in standard Tape & Reel (TR) format. Both are suitable for applications where the 320mcd brightness level meets circuit requirements.

Physical dimension variations (3.20mm L vs. 3.00mm L, 2.10mm H vs. 1.85mm H) require PCB layout verification to confirm footprint compatibility within the target assembly.

Frequently Asked Questions (FAQ)

Q: Can HSMA-A100-R40J1 be used as a direct replacement for VLMK333U2AB-GS08?

A: HSMA-A100-R40J1 is electrically compatible within the 120° viewing angle and 20mA test current specifications. The 1.9V forward voltage is 0.2V lower than the original 2.1V specification. Substitution is valid for applications where the reduced brightness (unspecified mcd rating) and lower forward voltage do not compromise circuit function. PCB layout must accommodate the 3.20mm length and 2.10mm maximum height.

Q: What is the difference between HSMU-A100-R00J1 and HSMU-A100-S00J1?

A: Both parts are electrically identical with 2.2V forward voltage and 320mcd brightness rating. The primary difference is packaging: HSMU-A100-R00J1 is supplied in Cut Tape (CT) & Digi-Reel® format, while HSMU-A100-S00J1 is supplied in standard Tape & Reel (TR) format. Selection depends on assembly line equipment compatibility and inventory management requirements.

Q: Are there wavelength differences between the main part and substitutes?

A: Yes. The VLMK333U2AB-GS08 has a dominant wavelength of 616nm (peak 622nm), while substitute parts range from 590nm to 592nm dominant wavelength. All wavelengths remain within the amber spectrum range. Visual color appearance may differ slightly; applications requiring specific wavelength characteristics should evaluate this parameter.

Q: Do all parts meet the same moisture sensitivity requirements?

A: Yes. The main part and all three substitutes are rated MSL 2A (4 Weeks), indicating identical moisture sensitivity handling and storage requirements.

Q: What are the physical footprint considerations?

A: The main part measures 3.00mm L x 2.80mm W x 1.85mm H maximum. All substitutes measure 3.20mm L x 2.80mm W x 2.10mm H maximum. The 0.2mm length increase and 0.25mm height increase require verification against PCB layout constraints and component clearance specifications.

Q: Are all parts RoHS3 compliant?

A: Yes. The main part VLMK333U2AB-GS08 and all three substitute parts (HSMA-A100-R40J1, HSMU-A100-R00J1, HSMU-A100-S00J1) are ROHS3 compliant with REACH unaffected status.
