SPHWH2L3D30GD4W0F3 Equivalent & Substitute Parts

Part Overview

The SPHWH2L3D30GD4W0F3 is a surface-mount LED from Samsung Semiconductor's LH351B series, designed for warm white lighting applications at 2700K color temperature. This component delivers 105 lm at 85°C under 350mA test current with a 120° viewing angle in a compact 3535 metric package (1414 case).

The product carries a "Not For New Designs" status, indicating Samsung has discontinued active development for this part number. This status necessitates identification of equivalent substitute components to maintain design continuity and ensure supply chain availability for existing applications and legacy system support.

Substitute Part Grouping Explanation

Substitution eligibility for the SPHWH2L3D30GD4W0F3 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Color: White, Warm
• CCT: 2700K
• Forward Voltage (Typ): 2.8V
• Test Current: 350mA
• Viewing Angle: 120°
• Package / Case: 1414 (3535 Metric)
• Size: 3.50mm × 3.50mm
• Height (Seated, Max): 2.06mm
• Mounting Type: Surface Mount
• Thermal Resistance: 4°C/W

Allowable Variation Parameters:

• Flux @ 85°C: 90–120 lm range (specification tolerance)
• CRI: May vary within acceptable limits for warm white applications
• Maximum Current: 1.5A (design headroom parameter)

The substitute part SPHWH2L3D30ED4W0F3 meets all mandatory matching criteria and operates within the specified flux tolerance band, confirming its status as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Substitution Basis:

The SPHWH2L3D30ED4W0F3 is a direct parametric equivalent to the SPHWH2L3D30GD4W0F3. Both components share identical electrical, optical, and mechanical specifications across all critical parameters. The sole difference is the CRI value (90 versus 80), which represents a variation within acceptable tolerances for warm white LED applications and does not affect functional compatibility in circuit design or thermal management.

Compliance Considerations:

Both parts carry RoHS Compliant certification and identical MSL ratings (2A, 4 Weeks), ensuring equivalent environmental and handling requirements. Both maintain "Not For New Designs" status from Samsung Semiconductor, indicating both are legacy components suitable for replacement applications and supply chain continuity only.

Selection Criteria:

• Use SPHWH2L3D30ED4W0F3 when supply of the primary part number is unavailable
• Verify application tolerance for CRI 80 versus CRI 90 in color-critical lighting applications
• Confirm thermal management design accommodates 4°C/W thermal resistance in both cases
• Ensure PCB layout and reflow profiles remain compatible with 3535 metric package specifications

Frequently Asked Questions (FAQ)

Q: Can SPHWH2L3D30ED4W0F3 be used as a direct replacement for SPHWH2L3D30GD4W0F3?

A: Yes. Both parts are parametric equivalents with identical electrical, optical, and mechanical specifications. The CRI difference (80 versus 90) does not affect circuit-level compatibility or thermal performance. Verify application requirements for color rendering index before substitution.

Q: What is the difference between these two part numbers?

A: The primary difference is the CRI value: SPHWH2L3D30GD4W0F3 has CRI 90, while SPHWH2L3D30ED4W0F3 has CRI 80. All other parameters—forward voltage, test current, flux output, viewing angle, package dimensions, and thermal characteristics—are identical.

Q: Are both parts still available from Samsung?

A: Both parts carry "Not For New Designs" status, indicating Samsung has discontinued active development. Availability depends on distributor inventory. SPHWH2L3D30GD4W0F3 has 1124 pcs in stock; SPHWH2L3D30ED4W0F3 has 700 pcs in stock at the time of this reference.

Q: Will the substitute part fit my existing PCB layout?

A: Yes. Both parts use identical 3535 metric (1414 case) packaging with 3.50mm × 3.50mm footprint and 2.06mm maximum seated height. PCB land patterns and reflow profiles require no modification.

Q: What is the thermal impact of using the substitute?

A: No thermal impact. Both parts have identical thermal resistance of 4°C/W. Thermal management design calculations and heat dissipation requirements remain unchanged.

Q: Does the CRI difference affect brightness or power consumption?

A: No. Both parts deliver 105 lm at 85°C under 350mA test current with 107 lm/W efficacy. CRI affects color rendering quality, not luminous output or electrical power requirements.

Q: Are there any handling or storage differences?

A: No. Both parts share identical MSL rating of 2A (4 Weeks), requiring the same moisture control and storage conditions during manufacturing and assembly.

Q: Can I mix these parts in the same production batch?

A: Yes, provided your application design accepts CRI 80 performance. Both parts are electrically and mechanically interchangeable. Document part number usage in bill of materials and assembly documentation for traceability.
