Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SML-LX1610SYC is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Color: Yellow
• Wavelength: 590nm (Typ)
• Current - Test: 350mA
• Voltage - Forward (Vf) (Typ): 2.1V
• Temperature - Test: 25°C
• Mounting Type: Surface Mount
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Size / Dimension: 0.335" L x 0.335" W (8.50mm x 8.50mm)
• Height - Seated (Max): 0.130" (3.30mm)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 2 (1 Year)

Allowable Variation Parameters:

• Viewing Angle: May differ from 70° specification
• Product Status: Active status preferred for ongoing availability

The identified substitute part maintains all mandatory electrical, optical, and mechanical specifications while offering improved product status and availability.

Parameter Comparison

Engineering Selection Recommendations

The SML-LX1610SYC/A is a direct functional equivalent to the obsolete SML-LX1610SYC. Both parts share identical electrical characteristics (350mA test current, 2.1V forward voltage), optical properties (590nm yellow wavelength), and mechanical specifications (TO-252-3 DPAK package, 8.50mm x 8.50mm footprint, 3.30mm maximum height).

The primary distinction is product status: SML-LX1610SYC/A maintains active status with Lumex Opto/Components Inc., ensuring ongoing availability and supply chain continuity. Both parts comply with ROHS3 and REACH requirements, with identical MSL rating of 2 (1 Year).

The SML-LX1610SYC/A features a 110° viewing angle compared to the 70° specification of the original part. This represents an expanded light distribution characteristic that does not restrict compatibility in applications designed for the original 70° specification.

For new designs and procurement of replacement components, SML-LX1610SYC/A is the appropriate selection based on active product status and full electrical and mechanical equivalence.

Frequently Asked Questions (FAQ)

Q: Can SML-LX1610SYC/A be used as a direct replacement for SML-LX1610SYC in existing designs?

A: Yes. The SML-LX1610SYC/A maintains identical electrical specifications (350mA current, 2.1V forward voltage), optical output (590nm yellow), and mechanical package (TO-252-3 DPAK, 8.50mm x 8.50mm). No circuit modifications are required.

Q: What is the significance of the wider 110° viewing angle in SML-LX1610SYC/A?

A: The substitute part provides a 110° viewing angle versus the original 70° specification. This represents a broader light distribution pattern. Applications designed for 70° viewing angle will function with the wider angle characteristic without performance degradation.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both SML-LX1610SYC and SML-LX1610SYC/A are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 2 (1 Year) for both parts.

Q: Why is the original SML-LX1610SYC listed as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The SML-LX1610SYC/A represents the active equivalent from Lumex Opto/Components Inc., ensuring continued availability for new procurement and design implementations.

Q: Are the package dimensions identical between both parts?

A: Yes. Both parts use TO-252-3 DPAK packaging with identical dimensions: 0.335" L x 0.335" W (8.50mm x 8.50mm) and maximum seated height of 0.130" (3.30mm). PCB footprints are interchangeable.

Q: What is the base product number for these parts?

A: The base product number is SML-LX1610. Both SML-LX1610SYC and SML-LX1610SYC/A are variants within this product family.
