Key Parameters

Substitute Part Grouping Explanation

Substitution of the LA T67F-V2AB-24-1-20-R18-Z is constrained by the following critical parameters:

Electrical Compatibility Parameters:

• Forward voltage (Vf): 1.96V nominal
• Test current: 20mA
• Viewing angle: 120°
• Wavelength specification: 618nm dominant wavelength (amber color)

Mechanical Compatibility Parameters:

• Mounting type: Surface Mount
• Package configuration: 2-PLCC or equivalent 2-lead SMD package
• Lens transparency: Clear
• Lens color: Colorless

Compliance & Environmental Parameters:

• RoHS3 compliance required
• Moisture Sensitivity Level: 2 (1 Year)
• ECCN: EAR99
• HTSUS: 8541.41.0000

The substitute part KS DELPS1.22-TIVH-68-H3Q4-20-S shares the same manufacturer, series designation (TOPLED®), mounting type, compliance certifications, and test current. However, this substitute differs in color specification (red vs. amber), wavelength (628nm vs. 618nm), forward voltage (2.2V vs. 1.96V), and package form factor (2-SMD Flat Lead vs. 2-PLCC). These differences indicate the substitute is not electrically or optically interchangeable for applications requiring amber indication at the specified wavelength and voltage.

Parameter Comparison

Engineering Selection Recommendations

The LA T67F-V2AB-24-1-20-R18-Z is classified as Last Time Buy, requiring proactive component sourcing for future production. Current inventory of 730 pieces is available from original stock.

The listed substitute part KS DELPS1.22-TIVH-68-H3Q4-20-S is manufactured by the same supplier and maintains ROHS3 compliance and identical moisture sensitivity ratings. However, this part is not functionally equivalent due to:

1. Color and Wavelength Mismatch: Red (628nm) versus amber (618nm) wavelength specifications result in different optical output characteristics unsuitable for amber indication applications.

2. Electrical Parameter Divergence: Forward voltage of 2.2V versus 1.96V requires circuit redesign for proper current limiting and voltage regulation.

3. Brightness Differential: 680mcd versus 1350mcd represents a 50% reduction in luminous intensity.

4. Package Form Factor Incompatibility: 2-SMD Flat Lead versus 2-PLCC package configuration requires PCB layout modification and different soldering procedures.

5. Active Product Status: The substitute maintains active production status, ensuring long-term availability compared to the Last Time Buy designation of the main part.

For applications requiring amber indication at the specified wavelength and electrical parameters, direct replacement with an equivalent amber LED in 2-PLCC package configuration from the TOPLED® series is necessary. For applications where color change to red is acceptable and circuit redesign is feasible, the KS DELPS1.22-TIVH-68-H3Q4-20-S provides an active alternative with improved long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the KS DELPS1.22-TIVH-68-H3Q4-20-S directly replace the LA T67F-V2AB-24-1-20-R18-Z in existing designs?

A: No. The substitute part differs in color (red vs. amber), wavelength (628nm vs. 618nm), forward voltage (2.2V vs. 1.96V), package type (2-SMD Flat Lead vs. 2-PLCC), and brightness (680mcd vs. 1350mcd). Direct substitution without circuit and PCB modifications is not possible.

Q: What is the significance of the Last Time Buy status for the LA T67F-V2AB-24-1-20-R18-Z?

A: Last Time Buy indicates the manufacturer has discontinued production. The 730 pieces currently in stock represent the final available inventory. New designs should transition to active product alternatives to ensure long-term component availability.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the LA T67F-V2AB-24-1-20-R18-Z and KS DELPS1.22-TIVH-68-H3Q4-20-S are ROHS3 compliant and classified under the same HTSUS code (8541.41.0000). Both maintain MSL 2 (1 Year) moisture sensitivity ratings.

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

A: The main part operates at 1.96V forward voltage with 1350mcd brightness at 618nm wavelength. The substitute operates at 2.2V forward voltage with 680mcd brightness at 628nm wavelength. These differences require independent circuit design calculations for each part.

Q: How do the package dimensions affect PCB design?

A: The LA T67F-V2AB-24-1-20-R18-Z measures 3.20mm L x 2.80mm W x 2.10mm H (2-PLCC package). The KS DELPS1.22-TIVH-68-H3Q4-20-S measures 1.40mm L x 0.80mm W x 0.70mm H (2-SMD Flat Lead package). The substitute is significantly smaller and requires different PCB footprint design and reflow soldering parameters.

Q: What is the viewing angle specification for both parts?

A: Both parts maintain a 120° viewing angle, indicating wide-angle indication capability suitable for general-purpose LED indication applications.

Q: Are there inventory considerations for component selection?

A: The LA T67F-V2AB-24-1-20-R18-Z has 730 pieces available as final stock. The KS DELPS1.22-TIVH-68-H3Q4-20-S has 39,702 pieces in active inventory, providing significantly greater long-term availability for new production requirements.
