Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWH3326MS3WAV3SD is determined by strict alignment of the following critical parameters:

Electrical Parameters:

• Color specification: White, Warm
• Color temperature: 3000K 3-Step MacAdam Ellipse
• Forward voltage (Vf): 2.75V typical
• Test current: 65mA
• Viewing angle: 120°
• CRI: 70

Mechanical Parameters:

• Package type: 4-SMD, Flat Leads
• Supplier device package: 5630
• Physical dimensions: 0.197" L x 0.118" W (5.00mm x 3.00mm)
• Maximum seated height: 0.031" (0.80mm)
• Mounting type: Surface Mount

Compliance Parameters:

• RoHS3 Compliant
• REACH Unaffected

The substitute part SPMWHD32AMV3XAV3SX meets all critical electrical and mechanical parameters. Differences in maximum current rating (200mA vs. 400mA) and thermal resistance (7.5°C/W vs. 12°C/W) do not disqualify substitution when the test current requirement of 65mA is maintained within the substitute's operational envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the SPMWH3326MS3WAV3SD and SPMWHD32AMV3XAV3SX are active production parts from Samsung Semiconductor with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on application current requirements and thermal management constraints.

The SPMWH3326MS3WAV3SD supports maximum current of 400mA with thermal resistance of 12°C/W. The SPMWHD32AMV3XAV3SX supports maximum current of 200mA with improved thermal resistance of 7.5°C/W. Both parts operate identically at the specified test current of 65mA with matching forward voltage, color temperature, and viewing angle specifications.

Applications operating at or below 200mA may utilize either part. Applications requiring operation above 200mA must use the SPMWH3326MS3WAV3SD. Thermal management considerations favor the SPMWHD32AMV3XAV3SX in high-ambient-temperature environments when current remains within its 200mA maximum rating.

Frequently Asked Questions (FAQ)

Q: Can SPMWHD32AMV3XAV3SX replace SPMWH3326MS3WAV3SD in all applications?

A: Substitution is valid when application current does not exceed 200mA. The substitute part meets all electrical and mechanical parameters at the 65mA test current. Applications requiring operation above 200mA must use the original SPMWH3326MS3WAV3SD.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 5630 package with dimensions of 0.197" L x 0.118" W (5.00mm x 3.00mm) and maximum seated height of 0.031" (0.80mm). PCB footprints and assembly processes are identical.

Q: What is the significance of the thermal resistance difference?

A: The SPMWHD32AMV3XAV3SX has lower thermal resistance (7.5°C/W vs. 12°C/W), resulting in better heat dissipation. This advantage applies only within the substitute's 200mA maximum current rating.

Q: Do both parts have the same color temperature specification?

A: Yes. Both parts are specified at 3000K with 3-Step MacAdam Ellipse tolerance, ensuring identical warm white color output and CRI of 70.

Q: Are packaging and tape specifications the same?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging and are compatible with standard SMD assembly equipment.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
