Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPHWH2L3D30CD4RTN3 is determined by strict alignment across the following critical parameters:

Color and Spectral Requirements: Both the main part and substitute must operate at 5000K cool white color temperature with CRI of 70 to maintain consistent color rendering in end-use applications.

Electrical Compatibility: Forward voltage, test current, and maximum current ratings must be within acceptable operating ranges. The substitute must support 350mA test current operation and 1.5A maximum current rating.

Optical Performance: Luminous flux output and luminous efficiency must be equivalent to support the same lighting intensity and power efficiency requirements.

Package and Mechanical Compatibility: Both components must use the 1414 (3535 Metric) surface-mount package with identical mounting type and thermal characteristics to ensure PCB layout compatibility and thermal management equivalence.

Regulatory and Compliance Status: Both parts must maintain RoHS compliance and equivalent moisture sensitivity ratings for manufacturing and storage compatibility.

The CreeLED XLamp® XP-G2 series part XPGBWT-01-0000-00KE3 meets all substitution criteria across these parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: The CreeLED XPGBWT-01-0000-00KE3 (XLamp® XP-G2) is the qualified equivalent for the obsolete Samsung SPHWH2L3D30CD4RTN3.

Justification Based on Provided Data:

The substitute part maintains active product status, ensuring long-term availability and manufacturing support compared to the obsolete main part. Both components share identical color temperature (5000K), CRI (70), test current (350mA), maximum current (1.5A), luminous efficiency (168 lm/W), package type (1414/3535 Metric), mounting type (surface mount), and thermal resistance (4°C/W).

Electrical parameters show minimal variance: forward voltage differs by 0.08V (2.8V vs. 2.72V), and luminous flux at 85°C differs by 5lm within acceptable tolerance ranges. Mechanical dimensions are compatible with negligible differences in length/width (0.05mm) and height (0.33mm). Both parts maintain RoHS compliance.

Compliance Considerations:

Both parts carry RoHS Compliant status and equivalent ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The substitute carries additional REACH Unaffected designation, providing expanded regulatory coverage.

Packaging Transition:

The main part is supplied in Cut Tape (CT) & Digi-Reel® format, while the substitute uses Tape & Reel (TR) format. This difference requires verification of assembly equipment compatibility and procurement process adjustments but does not affect component functionality or performance.

Frequently Asked Questions (FAQ)

Q: Why is the Samsung LH351B SPHWH2L3D30CD4RTN3 being discontinued?

A: The part is classified as obsolete. The CreeLED XLamp® XP-G2 series provides equivalent functionality with active product status and ongoing manufacturer support.

Q: Are the forward voltage differences (2.8V vs. 2.72V) significant for circuit design?

A: The 0.08V difference is within typical operating tolerances for LED driver circuits. Circuit designs accommodating the original 2.8V specification will function with the 2.72V substitute without modification, as most LED drivers provide voltage regulation within this range.

Q: Will the 5° viewing angle difference (120° vs. 115°) affect optical performance?

A: The 5° difference is minimal and will not significantly impact light distribution in most applications. Applications requiring precise 120° beam angles should evaluate the specific optical requirements against the 115° specification of the substitute.

Q: Is the height difference (2.06mm vs. 2.39mm) a concern for PCB assembly?

A: The 0.33mm height difference is within standard PCB assembly tolerances. Verify clearance with surrounding components and reflow oven profiles, but this difference typically does not require design changes.

Q: Can I use the substitute in existing designs without modification?

A: The substitute is mechanically and electrically compatible with the original part. No circuit modifications are required. Verify packaging format compatibility with your assembly equipment, as the substitute uses Tape & Reel (TR) format instead of Cut Tape (CT) & Digi-Reel®.

Q: What is the inventory status for each part?

A: The Samsung LH351B SPHWH2L3D30CD4RTN3 has 814 pieces in stock. The CreeLED XLamp® XP-G2 XPGBWT-01-0000-00KE3 has 3065 pieces in stock, providing greater availability for production continuity.

Q: Are both parts RoHS compliant?

A: Yes, both the main part and substitute are RoHS Compliant. The substitute additionally carries REACH Unaffected status, providing expanded regulatory coverage for international markets.

Q: What is the moisture sensitivity level for storage?

A: The main part specifies MSL 2A (4 Weeks). The substitute does not provide explicit MSL data in the available specifications. Verify MSL requirements with the manufacturer before establishing storage protocols.
