Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTL-298DJ is determined by the following critical parameters:

• Lens size and form factor (5mm, T-1 3/4 through-hole radial package)
• Dual-color configuration (green and yellow emission)
• Diffused lens transparency
• Forward voltage compatibility (2.1V nominal for both colors)
• Test current rating (20mA for both colors)
• Physical height constraint (8.60mm maximum)
• Moisture sensitivity classification (MSL 1)

The SSL-LX5093GYW from Lumex Opto/Components Inc. meets these substitution criteria with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The SSL-LX5093GYW is the recommended substitute for the obsolete LTL-298DJ based on the following factors:

• Product status: The SSL-LX5093GYW maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance certifications: The SSL-LX5093GYW is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
• Electrical compatibility: Forward voltage specifications are within acceptable tolerance (2.2V green vs. 2.1V green; 2.1V yellow matches exactly).
• Mechanical compatibility: Identical package dimensions, lens size, and mounting configuration enable direct board-level substitution.
• Performance enhancement: The SSL-LX5093GYW provides improved luminous intensity (20mcd green, 15mcd yellow) and wider viewing angle (60° vs. 50°), offering superior optical performance.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX5093GYW be used as a direct replacement for the LTL-298DJ?

A: Yes. Both components share identical lens size (5mm T-1 3/4), package type (radial through-hole), color configuration (green/yellow), and physical height (8.60mm). Electrical parameters are compatible within standard design tolerances.

Q: What is the voltage difference between the two parts?

A: The SSL-LX5093GYW green forward voltage is 2.2V compared to 2.1V for the LTL-298DJ. This 0.1V difference is within typical LED tolerance ranges and does not affect circuit compatibility in standard current-limiting designs.

Q: Are there any compliance differences?

A: The SSL-LX5093GYW provides additional compliance documentation (ROHS3 and REACH status) compared to the obsolete LTL-298DJ, making it suitable for applications with regulatory requirements.

Q: Does the viewing angle difference affect substitution?

A: The SSL-LX5093GYW offers a wider viewing angle (60° vs. 50°), which is a performance enhancement. This does not create compatibility issues and may improve visibility in certain applications.

Q: Are the wavelength specifications identical?

A: Yes. Both parts emit at identical peak wavelengths: 565nm for green and 585nm for yellow, ensuring color consistency in indication applications.
