Key Parameters

Substitute Part Grouping Explanation

Substitution for the OVSTRGBBCR8 is determined by the following critical parameters:

Configuration Compatibility: The main part uses independent configuration, allowing direct substitution only with parts maintaining this same configuration or compatible pinout arrangement.

Package Footprint: The 6-SMD J-Lead package defines the physical mounting interface. Substitutes must maintain identical or compatible package geometry to ensure PCB layout compatibility.

Electrical Characteristics: Forward voltage and test current specifications must remain within acceptable operating ranges for existing circuit designs. Wavelength specifications (dominant and peak) determine color matching for visual indication applications.

Optical Performance: Millicandela ratings and viewing angle affect visibility and brightness perception. Lens transparency (clear vs. diffused) impacts light distribution characteristics.

Compliance & Availability: RoHS3 compliance and active product status ensure regulatory adherence and supply chain continuity.

The identified substitutes are OVSARGB4R8 and OVSTRGBB1CR8, both manufactured by TT Electronics/Optek Technology with active product status.

Parameter Comparison

Engineering Selection Recommendations

OVSTRGBB1CR8 - Primary Substitute

The OVSTRGBB1CR8 is the recommended substitute for direct replacement applications. This part maintains identical package geometry (6-SMD J-Lead), independent configuration, and matching 4.00mm lens diameter. Forward voltage specifications are lower (3.2V green and blue vs. 4V), reducing power consumption while maintaining compatible test current ratings at 50mA. The part is RoHS3 compliant with active product status, ensuring long-term supply availability. Millicandela ratings are comparable or superior across all color channels. Lens transparency differs (diffused vs. clear), which affects light distribution but does not prevent functional substitution in most indication applications.

OVSARGB4R8 - Alternative Substitute

The OVSARGB4R8 is an alternative option for applications where package size reduction is acceptable. This part features a smaller 4-PLCC package (3.20mm x 2.80mm) compared to the original 6-PLCC footprint, requiring PCB layout modification. Configuration differs (common anode vs. independent), necessitating circuit redesign. Test current is reduced to 20mA, lowering power requirements. Forward voltage specifications are identical for red (2V) and reduced for green and blue (3.2V). The part is RoHS3 compliant with active product status. This substitute is suitable only when PCB redesign and circuit reconfiguration are feasible.

Both substitutes maintain RoHS3 compliance and MSL 5A rating, ensuring regulatory and handling consistency with the original part.

Frequently Asked Questions (FAQ)

Q: Can OVSTRGBB1CR8 replace OVSTRGBBCR8 without circuit modification?

A: Yes, OVSTRGBB1CR8 is a direct package-compatible substitute. Both use 6-SMD J-Lead configuration with independent emitter control. Forward voltage is lower (3.2V vs. 4V for green and blue), which reduces power consumption but requires circuit current-limiting resistor adjustment. Lens transparency differs (diffused vs. clear), affecting light distribution characteristics.

Q: What are the key differences between the two substitute options?

A: OVSTRGBB1CR8 maintains the original 6-PLCC package footprint and independent configuration, requiring minimal PCB changes. OVSARGB4R8 uses a smaller 4-PLCC package with common anode configuration, requiring both PCB redesign and circuit reconfiguration. Current consumption differs: OVSTRGBB1CR8 operates at 50mA per color (matching original), while OVSARGB4R8 operates at 20mA per color.

Q: Does lens transparency affect functional compatibility?

A: Lens transparency (clear vs. diffused) affects light distribution and perceived brightness. Clear lenses concentrate light in a narrower beam, while diffused lenses spread light more uniformly. Both maintain 120° viewing angle. Application requirements determine whether this difference is acceptable.

Q: Are both substitutes RoHS3 compliant?

A: Yes, both OVSARGB4R8 and OVSTRGBB1CR8 are RoHS3 compliant with identical MSL 5A (24 Hours) ratings, matching the original part's regulatory and handling requirements.

Q: Why is the original OVSTRGBBCR8 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Both substitute parts are active products with confirmed inventory availability, ensuring supply chain continuity for new designs and production requirements.
