Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTST-C230UBKT is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 1206 (3216 Metric)
• Mounting configuration: Surface Mount, Bottom Entry
• Physical dimensions: 3.20mm L x 1.60mm W, 1.10mm max height
• Lens style: Rectangle with Flat Top

Optical Compatibility:

• Color: Blue
• Lens transparency: Clear
• Viewing angle: 130°

Electrical Compatibility:

• Forward voltage (Vf): 3.8V nominal
• Test current: 20mA
• Wavelength range: Blue spectrum (dominant wavelength 466nm)

The LTST-C230TBKT meets all mechanical and optical compatibility criteria. While the substitute exhibits different electrical characteristics (3.3V Vf, 470nm dominant wavelength, 104mcd brightness), these variations remain within acceptable parameters for blue LED indication applications using the same package and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

The LTST-C230TBKT is the manufacturer-recommended substitute for the obsolete LTST-C230UBKT. Both components share identical mechanical packaging, mounting configuration, and physical dimensions, ensuring direct PCB compatibility without layout modifications.

The LTST-C230TBKT maintains active product status with ROHS3 compliance certification, providing long-term supply chain availability. The substitute operates at a lower forward voltage (3.3V versus 3.8V) and delivers significantly higher brightness (104mcd versus 4.5mcd) while maintaining the same 20mA test current specification.

Both components carry identical REACH Unaffected status and EAR99 export classification. Moisture sensitivity levels are equivalent at 2A (4 Weeks).

Frequently Asked Questions (FAQ)

Q: Can LTST-C230TBKT be used as a direct replacement for LTST-C230UBKT?

A: Yes. Both components use identical 1206 (3216 Metric) packaging with surface mount, bottom entry configuration. Physical dimensions and mounting footprints are identical, enabling direct PCB substitution without layout changes.

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

A: The substitute operates at 3.3V forward voltage compared to 3.8V for the original part. The LTST-C230TBKT also provides 104mcd brightness versus 4.5mcd. Both maintain 20mA test current specification. The dominant wavelength shifts from 466nm to 470nm, remaining within the blue spectrum.

Q: Are there compliance or supply chain advantages to using the substitute?

A: The LTST-C230TBKT carries active product status, ensuring ongoing availability. It holds ROHS3 compliance certification, whereas the original part is obsolete. Both share identical REACH Unaffected status and EAR99 classification.

Q: Do moisture sensitivity requirements differ between these parts?

A: No. Both components specify 2A moisture sensitivity level with 4 Weeks maximum floor life, requiring identical handling and storage protocols.

Q: Will the higher brightness of the substitute affect circuit design?

A: Circuit design modifications may be necessary if the original design relied on the lower brightness characteristic of the LTST-C230UBKT. The 0.5V lower forward voltage of the substitute may also require resistor value adjustments in current-limiting circuits to maintain equivalent LED current.
