Key Parameters

Substitute Part Grouping Explanation

Substitution for the LTW-C192TL2 is determined by the following critical parameters:

• Package compatibility: 0603 (1608 Metric) surface mount form factor
• Color specification: White LED
• Lens configuration: Rectangle with Flat Top, 1.15mm x 0.80mm
• Viewing angle: 130°
• Mounting type: Surface Mount
• Electrical operating range: Forward voltage and test current within acceptable circuit design tolerances
• Physical dimensions: Length 1.60mm, width 0.80mm, height compatibility

The LTW-C193TS5 qualifies as a direct substitute based on matching package, color, lens style, lens size, viewing angle, and mounting type. Electrical parameters (forward voltage and brightness) fall within acceptable substitution ranges for white LED indication applications.

Engineering Selection Recommendations

The LTW-C193TS5 is the qualified substitute for the obsolete LTW-C192TL2. Selection is based on:

• Active product status: The LTW-C193TS5 is currently in production, ensuring long-term availability and supply chain continuity.
• Regulatory compliance: The LTW-C193TS5 carries ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements.
• Physical compatibility: Identical package, lens configuration, and mounting type ensure direct PCB footprint compatibility.
• Electrical compatibility: Forward voltage increase from 2.7V to 2.93V and brightness increase from 50mcd to 108.5mcd are within acceptable ranges for white LED indication circuits. Circuit design must account for the higher forward voltage and test current (5mA vs. 2mA).
• Packaging format: The LTW-C193TS5 is supplied in Tape & Reel format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the LTW-C193TS5 be used as a direct replacement for the LTW-C192TL2 in existing designs?

A: Yes, the LTW-C193TS5 is physically and functionally compatible. The package, lens style, lens size, and viewing angle are identical. Circuit design must accommodate the higher forward voltage (2.93V vs. 2.7V) and test current (5mA vs. 2mA).

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), forward voltage (2.7V vs. 2.93V), brightness rating (50mcd vs. 108.5mcd), maximum height (0.40mm vs. 0.45mm), and regulatory compliance certifications. The LTW-C193TS5 includes ROHS3 compliance and REACH Unaffected status.

Q: Are the physical dimensions compatible for PCB assembly?

A: Yes. Both parts use the 0603 (1608 Metric) package with identical length (1.60mm) and width (0.80mm). Maximum height differs by 0.05mm (0.40mm vs. 0.45mm), which does not affect standard PCB assembly or clearance requirements.

Q: What packaging formats are available?

A: The LTW-C192TL2 was supplied in bulk packaging. The LTW-C193TS5 is supplied in Tape & Reel (TR) format, standard for automated surface mount assembly.

Q: Are there compliance or certification differences?

A: The LTW-C193TS5 is ROHS3 compliant and REACH Unaffected. Compliance status for the obsolete LTW-C192TL2 is not specified in available documentation.
