Substitute Part Grouping Explanation

Substitute parts for the SPMWHD32AMD7XAQSS0 are identified based on strict electrical and mechanical parameter equivalence within the LM301B series. The substitution logic is based on the following criteria:

Critical Parameters for Substitution:

• Series designation (LM301B)
• Electrical characteristics: Forward voltage (2.75V), test current (65mA), maximum current (180mA)
• Optical output: Luminous flux at test conditions (31lm ±3lm range), lumens per watt (173 lm/W)
• Color rendering: CRI value (90)
• Mechanical compatibility: Package type (1212/3030 Metric), mounting type (Surface Mount), physical dimensions (3.00mm x 3.00mm), height (0.85mm max)
• Thermal characteristics: Package thermal resistance (7.5°C/W)
• Environmental compliance: MSL rating (2A), ECCN (EAR99), HTSUS code (8541.41.0000)

Allowable Variation:

• Color temperature (CCT) may vary within the cool white spectrum (5000K to 5700K) while maintaining all other electrical and mechanical parameters identical

The identified substitute part SPMWHD32AMD7XAR0S0 maintains complete electrical and mechanical equivalence with the main part, with the only difference being the CCT specification at 5000K versus 5700K.

Parameter Comparison

Engineering Selection Recommendations

Both the SPMWHD32AMD7XAQSS0 and SPMWHD32AMD7XAR0S0 are active products from Samsung Semiconductor, Inc., with identical electrical, mechanical, and thermal specifications. Selection between these parts should be based on the following engineering criteria:

Primary Selection Criteria:

1. Color Temperature Requirement: The main part operates at 5700K (daylight cool white), while the substitute operates at 5000K (neutral cool white). Selection depends on the specific CCT requirement of the application. Both fall within the cool white spectrum and maintain identical CRI (90) and luminous output (31lm at 65mA).

2. Inventory Availability: The substitute part SPMWHD32AMD7XAR0S0 has significantly higher inventory (13989 pieces) compared to the main part (1024 pieces), which may influence procurement decisions for high-volume applications.

3. Compliance and Certifications: Both parts carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000) and MSL ratings (2A, 4 Weeks), ensuring equivalent compliance for export and handling requirements.

4. Thermal and Electrical Performance: Both parts deliver identical thermal resistance (7.5°C/W), forward voltage (2.75V), and efficiency (173 lm/W), ensuring interchangeable thermal management and power supply design.

5. Package and Mounting Compatibility: Both parts use identical 1212 (3030 Metric) surface-mount packages with matching dimensions (3.00mm x 3.00mm) and height (0.85mm max), ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q1: Can SPMWHD32AMD7XAR0S0 be used as a direct replacement for SPMWHD32AMD7XAQSS0?

A: Yes, SPMWHD32AMD7XAR0S0 is a direct electrical and mechanical equivalent. The only difference is the color temperature specification: 5000K versus 5700K. Both are cool white LEDs with identical luminous output (31lm), forward voltage (2.75V), CRI (90), and package dimensions. Substitution is valid when the application can accept 5000K color temperature instead of 5700K.

Q2: What is the difference between 5700K and 5000K color temperature?

A: Both are cool white color temperatures. 5700K is closer to daylight (more blue-shifted), while 5000K is neutral cool white. The difference is perceptually subtle and both maintain identical CRI (90) for color rendering accuracy. Selection depends on the specific visual appearance required by the application.

Q3: Are the electrical operating parameters identical between these parts?

A: Yes. Both parts have identical forward voltage (2.75V typical), test current (65mA), maximum current (180mA), and luminous efficiency (173 lm/W). They operate identically in circuit designs and power supply configurations.

Q4: Do these parts have the same package and mounting compatibility?

A: Yes. Both use the 1212 (3030 Metric) surface-mount package with identical dimensions (3.00mm x 3.00mm) and maximum seated height (0.85mm). PCB layouts and reflow profiles are interchangeable without modification.

Q5: What is the thermal performance difference?

A: There is no difference. Both parts have identical thermal resistance of 7.5°C/W, ensuring equivalent thermal management characteristics in circuit designs.

Q6: Are there any compliance or handling differences?

A: No. Both parts carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000) and moisture sensitivity levels (MSL 2A, 4 Weeks). Handling, storage, and export compliance requirements are identical.

Q7: Which part should be selected for new designs?

A: Selection should be based on the specific color temperature requirement of the application. If 5700K daylight cool white is required, use SPMWHD32AMD7XAQSS0. If 5000K neutral cool white is acceptable, SPMWHD32AMD7XAR0S0 offers higher inventory availability (13989 pieces versus 1024 pieces).

Q8: Can these parts be mixed in the same assembly?

A: Electrically and thermally, yes. However, mixing 5700K and 5000K LEDs in the same visual assembly may result in perceptible color temperature variation. For uniform appearance, use a single color temperature specification across the assembly.

Q9: What is the CRI significance for these parts?

A: Both parts have CRI (Color Rendering Index) of 90, indicating excellent color rendering accuracy. This is suitable for applications requiring high-fidelity color reproduction, such as display backlighting, accent lighting, and general illumination where color accuracy is important.

Q10: Are there any viewing angle differences?

A: No. Both parts have identical 120° viewing angle, ensuring equivalent light distribution characteristics in optical designs.
