OVLAB6CB8 Equivalent & Substitute Parts

Part Overview

The OVLAB6CB8 is a blue 470nm LED indication component in a 3mm through-hole radial package, manufactured by TT Electronics/Optek Technology. This part features a diffused white lens with 600mcd brightness rating and operates at 3.6V forward voltage. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and inventory replenishment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OVLAB6CB8 is based on the following critical parameters that define functional equivalence:

• Color and Wavelength: Both parts must emit blue light at 470nm dominant wavelength for color-critical indication applications
• Mounting Type: Through-hole radial configuration required for PCB compatibility
• Lens Size: 3mm package class for mechanical fit in standard LED mounting holes
• Electrical Compatibility: Forward voltage and test current must be compatible with existing circuit designs
• Manufacturer Consistency: TT Electronics/Optek Technology maintains design continuity across the product line

The OVLBB4C7 qualifies as a substitute based on matching color, wavelength, mounting type, lens size, and manufacturer. Differences in lens transparency (clear vs. diffused), brightness rating, forward voltage, and viewing angle represent design trade-offs that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The OVLBB4C7 is an active product with current manufacturing support and ROHS3 compliance, providing supply chain continuity for applications requiring blue 470nm LED indication in 3mm through-hole packages. Selection of this substitute requires evaluation of the following design considerations:

Electrical Differences: The OVLBB4C7 operates at 3.2V forward voltage compared to 3.6V for the OVLAB6CB8. Circuit designs must accommodate this 0.4V reduction, which may require resistor value adjustments to maintain equivalent current limiting and brightness control.

Optical Differences: The OVLBB4C7 features a clear lens versus the diffused lens of the OVLAB6CB8, resulting in higher brightness (1800mcd vs. 600mcd) and narrower viewing angle (45° vs. 65°). Applications requiring diffused light distribution or lower brightness levels must account for these optical characteristics.

Mechanical Differences: The OVLBB4C7 has a reduced maximum height of 5.35mm compared to 9.50mm, providing improved PCB clearance in space-constrained designs.

Compliance: Both parts maintain REACH Unaffected status and equivalent regulatory classification (ECCN EAR99, HTSUS 8541.41.0000).

Frequently Asked Questions (FAQ)

Q: Can the OVLBB4C7 directly replace the OVLAB6CB8 without circuit modification?

A: Direct replacement requires circuit evaluation. The 0.4V lower forward voltage of the OVLBB4C7 may alter current flow through existing series resistors. Verify that the circuit design accommodates this voltage difference or adjust current-limiting resistor values accordingly.

Q: What is the impact of switching from a diffused to a clear lens?

A: The clear lens of the OVLBB4C7 produces a more focused light beam with higher intensity (1800mcd vs. 600mcd) and narrower viewing angle (45° vs. 65°). Applications requiring uniform light distribution across a wider viewing angle should evaluate whether the clear lens meets visibility requirements.

Q: Are there mechanical compatibility concerns?

A: Both parts use 3mm through-hole radial packages with compatible mounting. The OVLBB4C7 is 4.15mm shorter (5.35mm vs. 9.50mm maximum height), which may improve clearance in compact designs but should be verified against PCB layout constraints.

Q: What is the supply status difference between these parts?

A: The OVLAB6CB8 is obsolete with no ongoing manufacturing. The OVLBB4C7 is an active product with current production and inventory availability, ensuring long-term supply chain reliability.

Q: Are both parts compliant with current regulations?

A: Yes. Both parts maintain REACH Unaffected status. The OVLBB4C7 additionally carries ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions.
