OVLAG6CB8 Equivalent & Substitute Parts

Part Overview

The OVLAG6CB8 is a green diffused 3mm through-hole LED manufactured by TT Electronics/Optek Technology, designed for indication applications with a dominant wavelength of 527nm. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The diffused lens design provides a wide viewing angle of 65° with moderate brightness output of 2000mcd at 20mA test current and a forward voltage of 3.6V.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OVLAG6CB8 is based on the following critical parameters that define functional compatibility:

Primary Compatibility Criteria:

• Color: Green wavelength in the 525-527nm range
• Mounting Type: Through Hole radial configuration
• Lens Size: 3mm package class
• Electrical Characteristics: Forward voltage within acceptable circuit design tolerance (3.2V-3.6V range)
• Test Current: 20mA standard test condition
• Moisture Sensitivity: MSL 1 classification

The OVLBG4C7 qualifies as a substitute based on these parameters. While it differs in lens transparency (clear vs. diffused) and brightness output (8400mcd vs. 2000mcd), these differences represent functional enhancements rather than incompatibilities. The substitute maintains the same green wavelength family, through-hole mounting, 3mm package format, and compatible electrical operating range.

Parameter Comparison

Engineering Selection Recommendations

The OVLBG4C7 is the manufacturer-recommended substitute for the obsolete OVLAG6CB8. Both components share identical REACH compliance status (REACH Unaffected) and export classification (EAR99), ensuring regulatory continuity in applications requiring these certifications.

The OVLBG4C7 is classified as Active product status, providing assured long-term availability and supply chain stability compared to the obsolete OVLAG6CB8. Both components maintain MSL 1 (Unlimited) moisture sensitivity classification, indicating no special storage or handling requirements.

Circuit design considerations include the 0.4V forward voltage difference (3.6V vs. 3.2V). This difference is within typical design tolerance for LED indication circuits and may require minor current-limiting resistor adjustment to maintain consistent brightness output. The substitute's higher brightness output (8400mcd vs. 2000mcd) and narrower viewing angle (45° vs. 65°) represent performance enhancements suitable for applications where increased luminous intensity is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the OVLBG4C7 directly replace the OVLAG6CB8 without circuit modifications?

A: The OVLBG4C7 is electrically compatible as a through-hole radial 3mm green LED. The 0.4V forward voltage difference may require adjustment of current-limiting resistor values to maintain desired brightness levels. Verify circuit design parameters before implementation.

Q: What is the primary difference between these two parts?

A: The main differences are lens transparency (diffused vs. clear), brightness output (2000mcd vs. 8400mcd), viewing angle (65° vs. 45°), and physical height (9.50mm vs. 5.35mm). Both operate at 20mA test current with compatible green wavelengths in the 525-527nm range.

Q: Why is the OVLAG6CB8 obsolete?

A: The OVLAG6CB8 is classified as obsolete by the manufacturer. The OVLBG4C7 represents the active product line continuation from TT Electronics/Optek Technology for green 3mm through-hole LED applications.

Q: Are there any compliance or certification differences?

A: Both components share identical REACH compliance status (REACH Unaffected) and export classification (EAR99). No compliance barriers exist for substitution in regulated applications.

Q: Does the narrower viewing angle of the OVLBG4C7 affect compatibility?

A: The OVLBG4C7 provides a 45° viewing angle compared to the OVLAG6CB8's 65° angle. Applications requiring wide-angle indication may need design review. The clear lens of the OVLBG4C7 provides higher brightness concentration within its viewing cone.

Q: What is the height difference impact on PCB layout?

A: The OVLBG4C7 is significantly shorter (5.35mm vs. 9.50mm maximum height). This reduction may provide benefits for compact designs but requires verification that existing mechanical mounting and clearance specifications accommodate the shorter component.
