Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLMY32ABBB-GS08 is determined by the following critical parameters:

• Package Compatibility: 4-PLCC surface mount package with identical footprint dimensions (3.20mm L x 2.80mm W)
• Optical Characteristics: Yellow color with dominant wavelength in the 588–590nm range
• Electrical Performance: Forward voltage within acceptable operating range (1.85V–2.4V) at 50mA test current
• Mechanical Fit: Lens style (round with flat top), lens size (2.40mm diameter), and maximum height (≤2.10mm) must accommodate existing PCB layouts
• Viewing Angle: 120° viewing angle for consistent optical performance
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status required for equivalent substitution

The Würth Elektronik 150141YS73140 meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The 150141YS73140 from Würth Elektronik is a direct functional equivalent for the obsolete VLMY32ABBB-GS08. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system support.

The substitute part operates at a higher forward voltage (2.4V versus 1.85V) and delivers slightly lower luminous intensity (2000mcd versus 2125mcd). These differences remain within acceptable tolerance for yellow indication applications where the dominant wavelength remains within the 588–590nm specification band. The active product status of the 150141YS73140 ensures long-term availability and supply chain stability compared to the obsolete VLMY32ABBB-GS08.

Mechanical compatibility is confirmed: both components share identical footprint dimensions, lens geometry, and maximum height specifications, enabling direct PCB layout substitution without redesign.

Frequently Asked Questions (FAQ)

Q: Can the 150141YS73140 be used as a direct replacement for the VLMY32ABBB-GS08 on existing PCBs?

A: Yes. Both components use the 4-PLCC package with identical footprint dimensions (3.20mm L x 2.80mm W), lens style, lens size (2.40mm diameter), and maximum height (2.05mm versus 2.10mm). No PCB layout modifications are required.

Q: What is the impact of the forward voltage difference (1.85V versus 2.4V)?

A: The 150141YS73140 requires 0.55V additional forward voltage at 50mA test current. Circuit designs must accommodate this higher voltage drop. Current-limiting resistor values may require recalculation to maintain proper LED operating current.

Q: Are there wavelength differences between these components?

A: The VLMY32ABBB-GS08 has a dominant wavelength of 588nm, while the 150141YS73140 operates at 590nm. Both fall within the yellow indication spectrum and are visually indistinguishable in typical indication applications.

Q: Does the luminous intensity difference (2125mcd versus 2000mcd) affect functionality?

A: The 150141YS73140 delivers 125mcd less intensity at 50mA. For applications where brightness is critical, circuit design may require increased forward current to achieve equivalent luminous output. Verify that the component's absolute maximum ratings support higher current operation.

Q: What are the moisture sensitivity differences?

A: The VLMY32ABBB-GS08 has MSL 2A (4 weeks), while the 150141YS73140 has MSL 3 (168 hours). The substitute part requires more stringent moisture control during storage and handling. Ensure appropriate dry-pack storage and reflow procedures are followed.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the VLMY32ABBB-GS08 and 150141YS73140 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.
