Parameter Comparison

Engineering Selection Recommendations

The LTW-008ZDCG is the direct substitute for the obsolete LTW-008ZDL. Selection of the LTW-008ZDCG is supported by:

Product Status: The LTW-008ZDCG maintains active product status with current manufacturing availability (16,600 pcs in stock), whereas the LTW-008ZDL is obsolete.

Regulatory Compliance: The LTW-008ZDCG carries ROHS3 compliance and REACH unaffected status, providing assurance for applications subject to environmental regulations.

Electrical Performance: Forward voltage and millicandela ratings differ by less than 1%, and viewing angle differs by approximately 4.3%, all within typical design tolerances for LED indication applications.

Mechanical Compatibility: Identical package, mounting type, physical dimensions, and MSL rating ensure direct PCB compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the LTW-008ZDCG be used as a direct replacement for the LTW-008ZDL without PCB modification?

A: Yes. The LTW-008ZDCG shares identical package type (2-SMD, J-Lead), mounting configuration (Surface Mount, Right Angle), and physical dimensions (2.80mm L x 1.20mm W x 0.80mm height). No PCB layout changes are required.

Q: What are the electrical differences between these parts?

A: Forward voltage differs by 0.05V (3.3V vs. 3.25V), millicandela rating differs by 10mcd (1300mcd vs. 1290mcd), and viewing angle differs by 5° (115° vs. 110°). These variations are within typical design tolerances for LED indication circuits.

Q: Why is the LTW-008ZDL classified as obsolete?

A: Product status is determined by manufacturer lifecycle decisions. The LTW-008ZDCG represents the current active equivalent from Lite-On Inc.

Q: What packaging options are available?

A: The LTW-008ZDL was supplied in bulk packaging. The LTW-008ZDCG is available in Tape & Reel (TR) packaging, which is standard for high-volume production environments.

Q: Are there compliance differences between these parts?

A: The LTW-008ZDCG carries ROHS3 compliance and REACH unaffected status. Compliance information for the LTW-008ZDL was not provided in the technical data.

Q: What is the MSL rating for these components?

A: Both parts carry MSL 3 (168 Hours) rating, indicating identical moisture sensitivity and storage requirements.
