SPMWHD32AMD3XATSS0 Equivalent & Substitute Parts

Part Overview

The SPMWHD32AMD3XATSS0 is an LED lighting component manufactured by Samsung Semiconductor, Inc., classified as an LM301B series neutral white LED. This surface mount device operates at 4000K color temperature and delivers 39 lumens at 25°C under 65mA test current. The component is housed in a 1212 (3030 Metric) package and is currently in active product status with 1049 units available in stock.

Substitute parts become necessary when primary inventory is depleted, supply chain disruptions occur, or when alternative packaging configurations from the same manufacturer are required while maintaining identical electrical and mechanical performance specifications.

Substitute Part Grouping Explanation

Substitution of the SPMWHD32AMD3XATSS0 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part SPMWHD32AMD3XAT0S0 qualifies as a parametric equivalent based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Series designation: LM301B
• Color specification: White, Neutral
• CCT: 4000K
• Flux @ 25°C, Test Current: 39 lm (36–42 lm range)
• Forward Voltage (Vf) Typical: 2.75V
• Test Current: 65mA
• Maximum Current: 180mA
• Lumens per Watt: 218 lm/W
• CRI: 70

Mechanical Parameters (Must Match Exactly):

• Package / Case: 1212 (3030 Metric)
• Mounting Type: Surface Mount
• Size / Dimension: 3.00mm × 3.00mm
• Height - Seated (Max): 0.85mm
• Viewing Angle: 120°
• Thermal Resistance: 7.5°C/W

Compliance & Handling (Must Match Exactly):

• Moisture Sensitivity Level: 2A (4 Weeks)
• ECCN: EAR99
• HTSUS: 8541.41.0000
• Manufacturer: Samsung Semiconductor, Inc.
• Product Status: Active

The only difference between the main part and substitute is the packaging configuration designation in the part number suffix, which does not alter electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SPMWHD32AMD3XATSS0 and SPMWHD32AMD3XAT0S0 are active products manufactured by Samsung Semiconductor, Inc., and carry identical electrical and mechanical specifications. Selection between these parts should be based on the following engineering criteria:

Inventory Availability: The substitute part SPMWHD32AMD3XAT0S0 maintains higher stock levels (5564 units) compared to the primary part (1049 units), making it suitable for high-volume production runs or extended lead-time mitigation.

Compliance & Certification: Both parts carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000) and moisture sensitivity ratings (MSL 2A, 4 Weeks), ensuring equivalent compliance requirements for storage, handling, and export documentation.

Thermal & Optical Performance: Identical thermal resistance (7.5°C/W), luminous flux (39 lm @ 25°C), color temperature (4000K), and CRI (70) ensure interchangeable performance in lighting applications without circuit redesign or thermal management modifications.

PCB Layout & Assembly: Identical package dimensions (3.00mm × 3.00mm), height (0.85mm), and surface mount configuration permit direct substitution on existing PCB layouts without footprint or reflow profile adjustments.

Frequently Asked Questions (FAQ)

Q: Can SPMWHD32AMD3XAT0S0 be used as a direct replacement for SPMWHD32AMD3XATSS0 in production?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. No circuit modifications, PCB layout changes, or reflow profile adjustments are required. The parts are interchangeable at the component level.

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

A: The part numbers differ only in the packaging configuration suffix (SS0 versus 0S0). This designation reflects different tape and reel packaging formats from Samsung Semiconductor, Inc. All functional, electrical, and mechanical parameters remain identical.

Q: Are the thermal characteristics identical?

A: Yes. Both parts have a thermal resistance of 7.5°C/W. Thermal management calculations, heat sink requirements, and operating temperature derating curves are identical for both parts.

Q: Do these parts require different moisture handling procedures?

A: No. Both parts carry MSL 2A (4 Weeks) classification. Identical moisture sensitivity levels require the same storage conditions, bake-out procedures, and shelf-life management protocols.

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

A: Yes. Since all electrical and mechanical parameters are identical, mixing SPMWHD32AMD3XATSS0 and SPMWHD32AMD3XAT0S0 in the same assembly batch does not affect performance, reliability, or functionality. However, component traceability records should document the specific part numbers used.

Q: What is the viewing angle specification, and does it affect placement on the PCB?

A: Both parts have a 120° viewing angle. This specification defines the angular range over which luminous intensity remains above 50% of peak intensity. Viewing angle does not affect PCB placement or soldering procedures; it only influences the optical distribution pattern in the final application.

Q: Are forward voltage and current ratings identical?

A: Yes. Both parts operate at 2.75V typical forward voltage with a 65mA test current and 180mA maximum current rating. Circuit designs using current-limiting resistors or constant-current drivers require no modification.
