OVLGO0C8B9 Equivalent & Substitute Parts

Part Overview

The OVLGO0C8B9 is an orange 615nm LED indicator manufactured by TT Electronics/Optek Technology, designed for discrete 2V radial through-hole applications. This part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain compatibility with the original electrical specifications, mechanical form factor, and optical characteristics to ensure direct replacement capability in existing circuit designs.

Engineering Selection Recommendations

Primary Substitutes (Orange, 615nm Wavelength):

The Everlight Electronics 383-2USOC/S400-A6 and 383-2USOC/S400-A7 provide the closest electrical and optical match to the OVLGO0C8B9. Both parts maintain identical forward voltage (2.0V), test current (20mA), wavelength specifications (615nm dominant, 621nm peak), viewing angle (6°), and mechanical dimensions (8.90mm height). Both are active products with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The 383-2USOC/S400-A7 offers higher brightness (12500mcd versus 10000mcd), providing flexibility for applications with varying luminous intensity requirements.

The Broadcom HLMP-EJ08-WZ000 and HLMP-EJ30-NR0DD are active orange LEDs with compatible forward voltage (1.98V) and test current (20mA). The HLMP-EJ08-WZ000 maintains a narrow 8° viewing angle and 10750mcd brightness, suitable for applications requiring directional indication. The HLMP-EJ30-NR0DD provides a wider 30° viewing angle with reduced brightness (1290mcd), appropriate for applications prioritizing wide-angle visibility. Both are ROHS3 compliant and available in high inventory quantities.

Secondary Substitutes (Yellow Wavelength):

Yellow LED substitutes (383-2UYC/S530-A3, 5219466F, LTL2R3KSK, MV8305) are applicable only when color change from orange to yellow is acceptable within the application context. These parts maintain compatible forward voltage (2.0V–2.2V) and test current (20mA) specifications. The 383-2UYC/S530-A3 and LTL2R3KSK are active products with ROHS3 compliance and standard T-1 3/4 form factors. The MV8305 is an active product with high inventory availability (124,344 units) and ROHS3 compliance, offering cost-effective procurement for high-volume applications.

Obsolete Parts:

The MV8303 (onsemi) is classified as obsolete and should not be selected for new designs or long-term procurement strategies, despite specification compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 383-2USOC/S400-A6 directly replace the OVLGO0C8B9?

A: Yes. Both parts share identical electrical specifications (2.0V forward voltage, 20mA test current), optical characteristics (615nm dominant wavelength, 6° viewing angle), and mechanical dimensions (5mm T-1 3/4 form factor, 8.90mm height). The 383-2USOC/S400-A6 is an active product with ROHS3 compliance, providing superior long-term availability compared to the obsolete OVLGO0C8B9.

Q: What is the difference between the HLMP-EJ08-WZ000 and HLMP-EJ30-NR0DD?

A: Both are Broadcom orange LEDs with identical forward voltage (1.98V) and test current (20mA). The primary differences are viewing angle and brightness: the HLMP-EJ08-WZ000 provides 8° viewing angle with 10750mcd brightness, while the HLMP-EJ30-NR0DD provides 30° viewing angle with 1290mcd brightness. Selection depends on application requirements for directional versus wide-angle indication.

Q: Can yellow LEDs substitute for the orange OVLGO0C8B9?

A: Yellow LEDs are functionally compatible from an electrical standpoint (matching forward voltage and test current specifications) but differ in optical output color and wavelength. Substitution is valid only when the application permits color change from orange (615nm) to yellow (589nm–590nm). Visual indication function remains equivalent; however, color-coded status indication applications require orange output.

Q: What is the significance of the millicandela rating difference between substitute parts?

A: Millicandela rating indicates luminous intensity. The OVLGO0C8B9 provides 16000mcd, while substitutes range from 1290mcd to 12500mcd. Selection depends on application requirements for brightness. Higher millicandela ratings (10000mcd–12500mcd) are suitable for applications requiring bright indication; lower ratings (1290mcd–4263mcd) are appropriate for applications with reduced brightness requirements or power constraints.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed (Everlight, Broadcom, Lite-On, Dialight, Fairchild) are ROHS3 compliant. The obsolete parts (OVLGO0C8B9, MV8303) do not carry ROHS3 certification. For applications requiring regulatory compliance with RoHS Directive 2011/65/EU, selection must be limited to active, ROHS3-compliant alternatives.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in Bulk and Cut Tape (CT) packaging. The HLMP-EJ30-NR0DD is available in Cut Tape packaging with the highest inventory quantity (19,741 units), suitable for high-volume automated assembly. Everlight and other manufacturers provide Bulk packaging options for standard procurement workflows.
