Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCS8TT93HPL2TUS03F is determined by the following critical parameters:

Color Temperature & Rendering: Neutral white 4000K with CRI 80 is the primary functional requirement. Substitute parts must maintain identical color temperature and CRI specifications to ensure visual consistency in lighting applications.

Luminous Flux Output: The 111 lm output at 85°C and 150mA establishes the baseline brightness requirement. Substitute parts must deliver equivalent or superior flux output within the specified test conditions.

Electrical Characteristics: Forward voltage (5.9V typical) and test current (150mA) define the electrical operating point. Substitute parts must operate within compatible voltage and current ranges to function in existing circuit designs.

Package & Form Factor: The 0505 (1313 Metric) surface-mount package with 1.34mm × 1.34mm footprint and 0.52mm maximum height constrains physical placement. Substitute parts must fit equivalent or smaller package envelopes to maintain PCB layout compatibility.

Compliance & Status: RoHS compliance and MSL 2A rating are mandatory for production and storage requirements. Substitute parts must meet or exceed these certifications.

The identified substitute SCP8TTJ5HEL1TLPF6E shares the same color temperature (4000K), CRI (80), and RoHS compliance. However, it operates in a larger 1111 (2828 Metric) package with different electrical characteristics (2.9V, 700mA), requiring circuit redesign for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Assessment: The SCP8TTJ5HEL1TLPF6E cannot serve as a direct pin-compatible replacement for the SCS8TT93HPL2TUS03F due to fundamental differences in package size, electrical operating point, and optical characteristics.

Compliance Basis: Both parts maintain RoHS compliance and identical MSL 2A ratings, satisfying regulatory and storage requirements. The substitute's active product status ensures ongoing availability and supply chain continuity compared to the obsolete main part.

Circuit Redesign Requirements: Implementation of the SCP8TTJ5HEL1TLPF6E requires:

• Power supply modification to accommodate 2.9V forward voltage (versus 5.9V)
• Current limiting circuit redesign for 700mA operation (versus 150mA)
• PCB layout revision to accommodate 2.80mm × 2.80mm footprint (versus 1.34mm × 1.34mm)
• Optical system adjustment for 120° viewing angle (versus 145°)

Luminous Output Consideration: The substitute delivers 320 lumens at 85°C, representing 188% higher flux output than the main part's 111 lumens. This increased brightness may require optical diffusion or intensity control in applications where the original 111 lm output was specified.

Efficiency Advantage: The substitute achieves 158 lm/W efficiency compared to the main part's 125 lm/W, providing 26% better energy conversion. This efficiency gain partially offsets the higher current requirement in system-level power consumption analysis.

Frequently Asked Questions (FAQ)

Q: Can the SCP8TTJ5HEL1TLPF6E replace the SCS8TT93HPL2TUS03F without circuit modification?

A: No. The substitute operates at 2.9V forward voltage and 700mA test current, compared to the main part's 5.9V and 150mA. The larger 1111 (2828 Metric) package is also incompatible with PCB layouts designed for the 0505 (1313 Metric) footprint. Complete circuit and layout redesign is required.

Q: Do both parts have identical color temperature specifications?

A: Yes. Both parts are specified as neutral white 4000K with CRI 80. The substitute includes 5-Step MacAdam Ellipse binning, which provides tighter color consistency across production batches.

Q: What is the primary reason for substitution?

A: The SCS8TT93HPL2TUS03F is classified as obsolete. The SCP8TTJ5HEL1TLPF6E is an active product from the same manufacturer with identical color temperature and CRI, ensuring long-term supply availability.

Q: How does the viewing angle difference affect application suitability?

A: The main part provides 145° viewing angle, while the substitute offers 120°. The narrower beam of the substitute concentrates light output over a smaller solid angle, requiring optical system redesign if wide-angle illumination is required.

Q: Are storage and handling requirements identical?

A: Yes. Both parts carry MSL 2A (4 Weeks) moisture sensitivity rating, requiring identical storage conditions and desiccant packaging protocols.

Q: What is the thermal performance comparison?

A: Both parts have identical thermal resistance of 2°C/W, indicating equivalent heat dissipation characteristics. Thermal management design can remain unchanged if circuit modifications are implemented.

Q: Does the substitute's higher efficiency reduce overall system power consumption?

A: The substitute achieves 158 lm/W versus the main part's 125 lm/W. However, the substitute's 700mA operating current (versus 150mA) results in higher absolute power draw. System-level power consumption depends on the specific circuit design and brightness requirements.
