Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSL-LX203CGT is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Color: Green
• Lens Transparency: Clear
• Voltage - Forward (Vf) Typical: 2.2V
• Current - Test: 20mA
• Wavelength - Peak: 565nm
• Mounting Type: Through Hole
• Package / Case: Radial
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Allowable Variation Parameters:

• Millicandela Rating: May vary based on application requirements
• Viewing Angle: May vary based on application requirements
• Lens Size: May vary based on PCB layout constraints
• Height (Max): May vary based on PCB clearance requirements
• Supplier Device Package: May vary (T-2mm vs. T-1)

The SSL-LX3044GT qualifies as a substitute part because it maintains all critical matching parameters while offering different specifications in allowable variation categories.

Parameter Comparison

Engineering Selection Recommendations

The SSL-LX3044GT is an active product substitute for the obsolete SSL-LX203CGT. Both components maintain identical forward voltage (2.2V), test current (20mA), and peak wavelength (565nm) specifications, ensuring electrical compatibility in green LED indication circuits.

Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

The SSL-LX3044GT offers higher luminous intensity (40mcd versus 6mcd) and a narrower viewing angle (30° versus 160°), which may require circuit design evaluation depending on application requirements. The substitute part uses a T-1 package with increased height (4.60mm versus 2.50mm), necessitating verification of PCB layout clearance and mounting compatibility.

The SSL-LX3044GT is available in significantly higher inventory (49,557 pieces) compared to the main part (884 pieces), supporting production continuity and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX3044GT directly replace the SSL-LX203CGT without circuit modification?

A: Electrical compatibility is confirmed. Both components operate at 2.2V forward voltage with 20mA test current and identical peak wavelength (565nm). However, PCB layout verification is required due to differences in package size (T-2mm versus T-1) and maximum height (2.50mm versus 4.60mm).

Q: What is the impact of the increased millicandela rating (40mcd versus 6mcd)?

A: The SSL-LX3044GT provides higher luminous intensity. Circuit current-limiting resistor values may require adjustment to maintain consistent brightness levels in the application. Verify that the application can accommodate increased light output.

Q: How does the viewing angle difference affect substitution?

A: The SSL-LX203CGT provides 160° viewing angle (wide distribution), while the SSL-LX3044GT provides 30° viewing angle (narrow, directional). Application requirements determine acceptability. Directional viewing may be suitable for focused indication applications but unsuitable for wide-angle visibility requirements.

Q: Are there packaging or handling differences between these components?

A: The SSL-LX3044GT is supplied in bulk packaging, while the SSL-LX203CGT uses standard packaging. Both components have identical moisture sensitivity level (MSL 1 - Unlimited), requiring no special storage or handling modifications.

Q: Why is the SSL-LX203CGT classified as obsolete?

A: Product status reflects manufacturer discontinuation. The SSL-LX3044GT, as an active product from the same manufacturer, provides continued access to equivalent green LED indication functionality.
