Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLMK32ABBB-GS08 is determined by the following critical parameters:

• Package compatibility: 4-PLCC surface mount configuration
• Mounting type: Surface mount
• Mechanical dimensions: 3.20mm L x 2.80mm W, 2.10mm maximum height
• Electrical operating parameters: Forward voltage, test current, and luminous intensity
• Wavelength range: Dominant wavelength in the amber-to-orange spectrum (606nm–616nm)
• Viewing angle: 120° minimum
• Regulatory compliance: ROHS3 compliance and REACH unaffected status

The identified substitute part 5973209202F from Dialight meets these substitution criteria within allowable parameter tolerances for the 4-PLCC LED indication category.

Parameter Comparison

Engineering Selection Recommendations

The 5973209202F substitute part maintains mechanical and package compatibility with the VLMK32ABBB-GS08 across all critical dimensions and mounting requirements. Both components are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for equivalent component selection.

The primary electrical differences are forward voltage (1.85V versus 2.15V) and dominant wavelength (616nm amber versus 606nm orange). These parameters must be evaluated within the context of the application circuit design. The substitute part delivers higher luminous intensity (2240mcd versus 2125mcd) at the specified 50mA test current.

The VLMK32ABBB-GS08 is obsolete with limited inventory availability. The 5973209202F is active production status with established supply chain availability, supporting long-term design continuity.

Frequently Asked Questions (FAQ)

Q: Can the 5973209202F directly replace the VLMK32ABBB-GS08 in existing PCB layouts?

A: Yes. Both components share identical 4-PLCC package dimensions (3.20mm L x 2.80mm W, 2.10mm height maximum) and surface mount configuration, enabling direct PCB footprint compatibility without layout modification.

Q: What is the impact of the wavelength difference between 616nm and 606nm?

A: The wavelength difference represents a shift from amber (616nm) to orange (606nm) in the visible spectrum. This affects the perceived color of the LED indication. Application-specific requirements determine whether this color shift is acceptable.

Q: Does the forward voltage difference of 0.30V affect circuit design?

A: The 5973209202F requires 2.15V typical forward voltage compared to 1.85V for the VLMK32ABBB-GS08. Circuit designs must accommodate this voltage difference through appropriate current-limiting resistor selection or voltage supply adjustment to maintain proper LED operation at 50mA test current.

Q: Are both parts suitable for high-reliability applications?

A: Both components meet ROHS3 compliance and REACH unaffected status. Moisture sensitivity levels differ: VLMK32ABBB-GS08 is MSL 2A (4 weeks) and 5973209202F is MSL 2 (1 year). Component selection should align with storage and handling requirements specific to the application environment.

Q: What is the significance of the product status difference?

A: The VLMK32ABBB-GS08 is obsolete with limited inventory (2697 pcs). The 5973209202F is active production status with established supply availability (812 pcs), supporting sustained production and future design iterations without supply chain constraints.
