SPMWHD32AMD7XAPSS0 LED Equivalent & Substitute Parts

Part Overview

The SPMWHD32AMD7XAPSS0 is an LED lighting component from the Samsung Semiconductor LM301B series, featuring cool white illumination at 6500K color temperature. This surface mount LED operates at 2.75V forward voltage with a test current of 65mA, delivering 31 lumens at 25°C and achieving 173 lumens per watt efficiency. The component is housed in a 1212 (3030 metric) package with a 120° viewing angle and is classified as Active product status. Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain consistent performance across production batches when the primary part number becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHD32AMD7XAPSS0 is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Series: LM301B
• Package / Case: 1212 (3030 Metric)
• Mounting Type: Surface Mount
• Forward Voltage (Vf) Typical: 2.75V
• Test Current: 65mA
• Maximum Current: 180mA
• Viewing Angle: 120°
• Thermal Resistance of Package: 7.5°C/W
• Moisture Sensitivity Level (MSL): 2A (4 Weeks)

Allowable Variation Parameters:

• CCT (Correlated Color Temperature): Substitutes within the cool white spectrum (5000K–6500K) are acceptable
• Flux @ 25°C: Must fall within the specified range of 28–34 lumens
• Lumens per Watt: Must maintain 173 lm/W efficiency
• Color Rendering Index (CRI): Must equal or exceed 90

The substitute part SPMWHD32AMD7XAR0S0 meets all mandatory matching criteria. The only variation is the CCT specification, which shifts from 6500K to 5000K, both within the cool white category and acceptable for applications where color temperature flexibility is permitted.

Parameter Comparison

Engineering Selection Recommendations

Both the SPMWHD32AMD7XAPSS0 and SPMWHD32AMD7XAR0S0 are classified as Active product status from Samsung Semiconductor, Inc., ensuring ongoing manufacturer support and compliance with current industry standards. Both components carry identical electrical and mechanical specifications with the exception of correlated color temperature.

Selection Criteria:

1. For 6500K Cool White Applications: Use SPMWHD32AMD7XAPSS0. This part number is specified when the application requires the higher color temperature of 6500K, typical in task lighting, display backlighting, or applications requiring enhanced visual clarity.

2. For 5000K Cool White Applications: Use SPMWHD32AMD7XAR0S0. This substitute is appropriate when the application permits or requires the neutral cool white spectrum at 5000K, commonly used in general illumination and balanced color rendering scenarios.

3. For Supply Chain Continuity: The SPMWHD32AMD7XAR0S0 substitute maintains significantly higher inventory availability (13,989 pieces versus 657 pieces), making it suitable for high-volume production runs or when extended lead times must be avoided.

Both parts maintain identical forward voltage, test current, maximum current, luminous flux, efficiency, CRI, viewing angle, thermal characteristics, and package dimensions. Substitution is electrically and mechanically transparent to the circuit design and PCB layout.

Frequently Asked Questions (FAQ)

Q1: Can SPMWHD32AMD7XAR0S0 be used as a direct replacement for SPMWHD32AMD7XAPSS0 in existing designs?

A: Yes, SPMWHD32AMD7XAR0S0 is a direct electrical and mechanical substitute. The only difference is the correlated color temperature (5000K versus 6500K). If the application does not require the specific 6500K color temperature, substitution requires no circuit modifications, PCB layout changes, or firmware adjustments. Both parts operate at identical voltage, current, and thermal parameters.

Q2: What is the significance of the CCT difference between 6500K and 5000K?

A: CCT (Correlated Color Temperature) describes the perceived color of the light. 6500K produces a cooler, more bluish-white light, while 5000K produces a neutral, daylight-balanced white light. Both are classified as cool white. The choice depends on application requirements: 6500K is preferred for high-contrast visual tasks, while 5000K is suitable for general illumination where neutral color balance is desired.

Q3: Are the package dimensions and mounting characteristics identical?

A: Yes. Both parts use the 1212 (3030 metric) package with dimensions of 3.00mm × 3.00mm and a maximum seated height of 0.85mm. Both are surface mount components with identical thermal resistance (7.5°C/W) and moisture sensitivity level (2A, 4 weeks). PCB footprints and reflow profiles are identical.

Q4: Do both parts have the same luminous flux output?

A: Yes. Both parts deliver 31 lumens at 25°C under 65mA test current, with an acceptable range of 28–34 lumens. Both achieve 173 lumens per watt efficiency and maintain a Color Rendering Index (CRI) of 90.

Q5: What is the inventory status difference, and does it affect part selection?

A: SPMWHD32AMD7XAPSS0 has 657 pieces in stock, while SPMWHD32AMD7XAR0S0 has 13,989 pieces available. For applications where supply chain continuity and rapid fulfillment are critical, the substitute part offers significantly better availability. For applications with specific 6500K requirements, the main part number must be used despite lower inventory levels.

Q6: Are there any compliance or certification differences between the two parts?

A: No. Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. Both are Active product status from Samsung Semiconductor, Inc., and both are supplied in Tape & Reel (TR) packaging with identical moisture sensitivity handling requirements.

Q7: Can these parts be used interchangeably in high-volume production?

A: Interchangeability depends on application specifications. If the design permits either 5000K or 6500K color temperature, the parts are fully interchangeable with no design changes required. If the design specifies 6500K exclusively, only SPMWHD32AMD7XAPSS0 is acceptable. For mixed-batch production, confirm with design engineering whether color temperature flexibility exists.
