Key Parameters

Substitute Part Grouping Explanation

The SSL-LX3044GD-12V from Lumex Opto/Components Inc. qualifies as a substitute based on the following alignment of critical parameters:

• Package Compatibility: Both components use T-1 (3mm) radial through-hole packages
• Mounting Type: Both are through-hole mounted
• Physical Envelope: SSL-LX3044GD-12V height of 4.60mm is within acceptable tolerance relative to QL205GT at 5.20mm for standard PCB applications
• Regulatory Alignment: SSL-LX3044GD-12V is ROHS3 compliant and REACH unaffected, providing compliance upgrade path
• Trade Classification: Identical HTSUS code (8541.41.0000) confirms equivalent product classification
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

The SSL-LX3044GD-12V represents the primary substitute for the obsolete QL205GT based on product lifecycle status and regulatory compliance. The QL205GT is no longer in active production, necessitating alternative sourcing for new designs and production replenishment.

The SSL-LX3044GD-12V offers improved regulatory standing through ROHS3 compliance, addressing environmental and supply chain requirements for modern applications. Both components share identical trade classification and moisture sensitivity ratings, ensuring equivalent handling and logistics treatment.

Physical dimensions are compatible within standard PCB assembly tolerances. The SSL-LX3044GD-12V's slightly reduced maximum height (4.60mm vs. 5.20mm) presents no constraint for through-hole applications using standard component spacing.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX3044GD-12V directly replace QL205GT in existing designs?

A: Yes, for applications where the specified electrical parameters of the SSL-LX3044GD-12V (12V forward voltage, 6mcd brightness, 565nm peak wavelength, 60° viewing angle) are compatible with circuit requirements. Physical package compatibility is confirmed through T-1 radial through-hole mounting.

Q: What is the primary reason for substitution?

A: The QL205GT is classified as obsolete and no longer manufactured by onsemi. The SSL-LX3044GD-12V is an active product with confirmed inventory availability.

Q: Are there compliance differences between these parts?

A: Yes. The QL205GT is RoHS non-compliant, while SSL-LX3044GD-12V is ROHS3 compliant. Both are REACH unaffected. For applications subject to RoHS requirements, the SSL-LX3044GD-12V is the appropriate selection.

Q: How do the physical dimensions compare?

A: Both use T-1 (3mm) packages. The SSL-LX3044GD-12V maximum height is 4.60mm compared to QL205GT at 5.20mm. This difference is within standard PCB assembly tolerances and does not affect through-hole mounting compatibility.

Q: What electrical parameters should be verified during substitution?

A: Confirm that the circuit design accommodates the SSL-LX3044GD-12V specifications: 12V forward voltage, 6mcd brightness output, 565nm peak wavelength, and 60° viewing angle. These parameters must align with the intended application requirements.

Q: Are moisture sensitivity ratings equivalent?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating identical moisture handling and storage requirements.
