Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SPHWH2L3D30ED4WMM3 is determined by strict alignment of the following critical parameters:

Color and Thermal Characteristics: Both the main part and substitute must operate at 2700K warm white color temperature with CRI of 80 or higher to maintain color rendering consistency in lighting applications.

Electrical Performance: Forward voltage (Vf) must be within compatible range (2.72V to 2.8V typical), and test current must be 350mA to ensure proper operation within existing circuit designs without requiring driver modifications.

Mechanical Compatibility: Package format must be 1414 (3535 metric) with surface mount mounting type. Physical dimensions (3.45mm to 3.50mm length/width, height 2.06mm to 2.39mm) must accommodate existing PCB layouts and thermal management structures.

Flux Output: Luminous flux at 85°C under 350mA test current must fall within the 135 lm to 155 lm range to maintain system-level brightness specifications.

Regulatory Compliance: Both parts must maintain RoHS compliance and equivalent ECCN/HTSUS classifications for supply chain continuity.

Maximum Current Rating: Both parts must support 1.5A maximum current to ensure safe operation within circuit protection parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: The CreeLED XPGBWT-H1-0000-00GE8 (XLamp® XP-G2 series) is the qualified equivalent for the obsolete Samsung SPHWH2L3D30ED4WMM3.

Justification Based on Provided Parameters:

The substitute part maintains all critical functional parameters required for direct replacement: identical 2700K color temperature, 80 CRI rating, 350mA test current, 1.5A maximum current rating, and 1414 (3535 metric) package format. Both parts are RoHS compliant and share equivalent thermal resistance (4°C/W).

The substitute's active product status ensures ongoing availability and supply chain continuity, addressing the primary limitation of the obsolete main part. Manufacturing by CreeLED, an established LED component supplier, provides equivalent quality assurance and regulatory compliance.

Performance Variance Considerations:

The substitute delivers 135 lm at 85°C versus the main part's 155 lm, representing a 12.9% reduction in luminous flux. This variance falls within typical manufacturing tolerances for warm white LED components and reflects generational efficiency differences between the LH351B and XP-G2 series. System-level brightness specifications must accommodate this flux differential through circuit design adjustments if required.

Forward voltage difference (2.72V substitute versus 2.8V main part) is 2.8%, well within standard LED driver tolerance ranges and does not require circuit redesign.

Viewing angle reduction from 120° to 115° (4.2% narrower) is negligible for most lighting applications and does not impact optical system design.

Physical dimension variance (3.45mm versus 3.50mm, height 2.39mm versus 2.06mm) is compatible with standard 3535 package footprints and does not require PCB layout modification.

Compliance Status:

Both parts maintain RoHS compliance and equivalent ECCN/HTSUS classifications (EAR99 / 8541.41.0000), ensuring regulatory continuity for export and supply chain documentation.

Frequently Asked Questions (FAQ)

Q1: Why is the Samsung SPHWH2L3D30ED4WMM3 classified as obsolete?

A: The Samsung LH351B series has reached end-of-life status in Samsung's product portfolio. Manufacturers discontinue LED product lines as newer generations with improved efficiency and performance characteristics become available. The obsolete designation indicates Samsung no longer manufactures or guarantees supply of this part number.

Q2: Can the CreeLED XPGBWT-H1-0000-00GE8 be used as a direct drop-in replacement?

A: The CreeLED XLamp® XP-G2 is mechanically and electrically compatible for direct PCB substitution. Both parts use identical 1414 (3535 metric) surface mount packages with matching footprints. However, the 12.9% lower luminous flux output (135 lm versus 155 lm at 85°C) must be evaluated against system brightness requirements. If the original design operated at maximum brightness specification, the substitute may require circuit adjustments to maintain equivalent light output.

Q3: What is the significance of the 2700K color temperature specification?

A: The 2700K correlated color temperature defines the warm white appearance of the LED, producing light similar to incandescent sources. This specification is critical for applications requiring consistent color rendering, such as residential lighting, hospitality environments, and color-critical display applications. Both the main part and substitute maintain identical 2700K specification with 80 CRI, ensuring color consistency.

Q4: How do the forward voltage differences (2.8V versus 2.72V) affect circuit design?

A: The 2.8% forward voltage difference is within standard LED driver tolerance ranges. Most constant-current LED drivers accommodate forward voltage variations of ±5% without requiring recalibration. If the original circuit uses a precision voltage-regulated supply rather than a current-regulated driver, verification of driver specifications is recommended to confirm compatibility.

Q5: Does the 4.2% viewing angle reduction (120° to 115°) impact optical performance?

A: The viewing angle difference is negligible for most lighting applications. Both angles exceed 100°, providing wide-angle light distribution suitable for general illumination. Applications requiring specific beam patterns should verify the 115° angle meets optical system requirements, but standard lighting designs accommodate this variance without modification.

Q6: What does the 16% height difference (2.06mm versus 2.39mm) mean for PCB assembly?

A: Both parts remain within standard 3535 package height specifications. The 0.33mm height difference does not affect PCB layout or reflow soldering processes. However, if the original design incorporated height-critical constraints (such as low-profile enclosures with minimal clearance), the taller substitute profile must be verified against mechanical envelope specifications.

Q7: How does the 10.1% efficiency difference (158 lm/W versus 142 lm/W) affect system power consumption?

A: The efficiency difference reflects generational improvements in LED technology. At identical 350mA test current, the main part produces 158 lumens per watt while the substitute produces 142 lumens per watt. For a fixed light output requirement, the substitute requires approximately 11% higher input power. System-level power budget analysis is recommended if power consumption is a critical design parameter.

Q8: Are there any supply chain or packaging differences between the parts?

A: The main part (SPHWH2L3D30ED4WMM3) is listed with standard packaging notation, while the substitute (XPGBWT-H1-0000-00GE8) is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume production and automated assembly processes. If manual component handling is required, reel format may necessitate minor procurement or assembly procedure adjustments.

Q9: What is the MSL (Moisture Sensitivity Level) rating and why does it matter?

A: The main part carries MSL 2A (4 Weeks), indicating the component can be exposed to ambient conditions (30°C, 60% relative humidity) for up to 4 weeks before soldering without baking. The substitute's MSL rating is not provided in the available data. Standard practice requires verification of the substitute's MSL specification before procurement to ensure proper storage and handling procedures align with manufacturing requirements.

Q10: Can both parts be used interchangeably in existing inventory?

A: Direct inventory interchangeability is not recommended without circuit validation. While both parts are mechanically and electrically compatible, the 12.9% flux difference and 10.1% efficiency difference may produce measurable brightness variations in assembled products. Quality control procedures should include photometric testing of assemblies using the substitute part to confirm system-level performance meets specifications before full production transition.
