Key Parameters

Substitute Part Grouping Explanation

Substitution of the LA T67F-V2AB-24-1-20-R33-Z is constrained by the following critical parameters:

Mandatory Compatibility Criteria:

• Surface mount mounting type
• 20mA test current operation
• 120° viewing angle
• Clear lens transparency
• Colorless lens color
• ROHS3 compliance
• MSL 2 (1 Year) moisture sensitivity rating

Functional Parameters:

• Forward voltage (Vf) within acceptable circuit design tolerance
• Millicandela output suitable for indication applications
• Wavelength in visible spectrum for intended color indication

The identified substitute part KS DELPS1.22-TIVH-68-H3Q4-20-S shares the core operational characteristics of surface mount LED indication with matching test current, viewing angle, lens properties, and compliance certifications. However, this substitute operates in the red spectrum (628nm dominant wavelength) rather than amber, and exhibits different electrical and photometric characteristics that require circuit-level evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The LA T67F-V2AB-24-1-20-R33-Z carries Last Time Buy status, indicating end-of-life production. The substitute part KS DELPS1.22-TIVH-68-H3Q4-20-S maintains Active product status with ams-OSRAM USA INC., ensuring continued availability and manufacturing support.

Compliance and Certification: Both components achieve ROHS3 compliance and maintain identical MSL 2 (1 Year) moisture sensitivity ratings, satisfying regulatory and environmental requirements for equivalent applications.

Electrical and Photometric Differences: The substitute part operates at 2.2V forward voltage compared to 1.96V for the original part, representing a 0.24V increase. The millicandela output differs significantly at 680mcd versus 1350mcd. These differences require circuit-level verification to confirm suitability for specific indication applications.

Package and Form Factor: The substitute employs a 2-SMD flat lead package with significantly reduced dimensions (1.40mm x 0.80mm x 0.70mm height) compared to the 2-PLCC package (3.20mm x 2.80mm x 2.10mm height). PCB layout and mechanical clearance must be evaluated for compatibility.

Color Spectrum: The substitute operates in the red spectrum (628nm dominant) rather than amber (618nm dominant). Application-specific requirements for color indication must be assessed independently.

Frequently Asked Questions (FAQ)

Q: Can the KS DELPS1.22-TIVH-68-H3Q4-20-S directly replace the LA T67F-V2AB-24-1-20-R33-Z without circuit modification?

A: Direct replacement without circuit modification is not supported. The substitute part differs in forward voltage (2.2V vs. 1.96V), millicandela output (680mcd vs. 1350mcd), color spectrum (red vs. amber), and package form factor (2-SMD flat lead vs. 2-PLCC). Circuit design review is required.

Q: What are the key compatibility parameters for LED indication substitution?

A: Core compatibility parameters include mounting type (surface mount), test current (20mA), viewing angle (120°), lens properties (clear, colorless), and compliance certifications (ROHS3, MSL 2). Forward voltage and millicandela output must be evaluated within specific circuit requirements.

Q: Does the package size difference affect PCB design?

A: Yes. The substitute part measures 1.40mm x 0.80mm x 0.70mm maximum height, compared to the original 3.20mm x 2.80mm x 2.10mm. PCB footprint, solder pad design, and mechanical clearance must be re-evaluated for the smaller 2-SMD flat lead package.

Q: Are both parts manufactured by the same company?

A: Both components are manufactured by ams-OSRAM USA INC., ensuring consistent quality standards and supply chain continuity.

Q: What is the significance of the Last Time Buy status on the original part?

A: Last Time Buy status indicates that the LA T67F-V2AB-24-1-20-R33-Z is no longer in active production. Existing inventory is available for final orders, but long-term supply cannot be guaranteed. Transition to an active product such as the KS DELPS1.22-TIVH-68-H3Q4-20-S is recommended for ongoing designs.

Q: How do the electrical characteristics differ between these parts?

A: The substitute operates at 2.2V forward voltage versus 1.96V, requiring 0.24V additional voltage drop across the LED. The millicandela rating is 680mcd compared to 1350mcd, representing approximately 50% lower light output at equivalent test current.

Q: Are moisture sensitivity levels equivalent?

A: Both components maintain MSL 2 (1 Year) moisture sensitivity ratings, indicating equivalent handling, storage, and reflow requirements.
