Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT541MD5WAP0S2 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Series family: LM561B or LM561B Plus
• Color specification: White, Cool
• CCT: 6500K
• Mounting type: Surface Mount
• Package type: 5630 (4-SMD configuration)
• Viewing angle: 120°
• Forward voltage (Vf): 2.95V
• Test current: 65mA
• Compliance: RoHS status and MSL rating

Allowable Variations:

• Flux output at 25°C: Substitute parts may exceed the original 29 lm specification
• Lumens/Watt efficiency: Substitute parts may demonstrate improved efficiency
• Maximum current rating: Substitute parts may have higher current capacity
• Thermal resistance: Substitute parts may have lower thermal resistance values
• Height and package lead configuration: Minor variations permitted within 5630 package family
• Product status: Active product status is preferred over end-of-life designation

The SPMWHT541MP5WAPKS4 qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SPMWHT541MP5WAPKS4

The SPMWHT541MP5WAPKS4 is the qualified substitute for SPMWHT541MD5WAP0S2 based on the following engineering criteria:

1. Product Status Alignment: The substitute is classified as "Active," ensuring continued availability and manufacturing support. The original part is "Not For New Designs," indicating end-of-life status and potential supply constraints.

2. Compliance Enhancement: The substitute meets ROHS3 compliance, which represents a more stringent environmental standard than the original RoHS Compliant designation. Both parts maintain identical MSL 2A (4 Weeks) moisture sensitivity ratings.

3. Electrical Compatibility: Forward voltage (2.95V) and test current (65mA) are identical, ensuring direct circuit compatibility without redesign. The substitute's maximum current rating of 180mA provides additional operational headroom compared to the original 150mA specification.

4. Optical Performance: The substitute delivers 33 lumens at 25°C versus 29 lumens for the original part, representing a 13.8% improvement in luminous flux. Efficiency increases from 151 lm/W to 167 lm/W. Color temperature (6500K) and CRI (80) remain unchanged.

5. Thermal Characteristics: The substitute exhibits lower thermal resistance (15°C/W versus 16°C/W) and a lower seated height (0.80mm versus 0.90mm), facilitating improved thermal management in compact designs.

6. Package Compatibility: Both parts use the 5630 package footprint with identical 5.00mm × 3.00mm dimensions. The lead configuration variation (Flat Lead Exposed Pad versus Flat Leads) is within acceptable tolerance for the 4-SMD family and does not affect PCB layout or reflow soldering processes.

Selection Conclusion: The SPMWHT541MP5WAPKS4 provides superior performance, active product status, and enhanced compliance while maintaining full electrical and mechanical compatibility with existing designs using SPMWHT541MD5WAP0S2.

Frequently Asked Questions (FAQ)

Q1: Can SPMWHT541MP5WAPKS4 be used as a direct drop-in replacement for SPMWHT541MD5WAP0S2?

A: Yes. Both parts share identical forward voltage (2.95V), test current (65mA), color temperature (6500K), viewing angle (120°), and 5630 package footprint. The substitute requires no circuit modifications and is compatible with existing PCB layouts and reflow profiles.

Q2: What are the key differences between these two parts?

A: The substitute (SPMWHT541MP5WAPKS4) offers improved luminous flux (33 lm versus 29 lm), higher efficiency (167 lm/W versus 151 lm/W), greater maximum current capacity (180mA versus 150mA), lower thermal resistance (15°C/W versus 16°C/W), and active product status. The original part is end-of-life.

Q3: Are there any compatibility concerns with the lead configuration difference?

A: No. The variation between "Flat Lead Exposed Pad" and "Flat Leads" is a minor configuration difference within the 5630 package family. Both configurations are compatible with standard SMD reflow soldering processes and do not affect PCB design or assembly procedures.

Q4: Does the lower height of the substitute part (0.80mm versus 0.90mm) affect PCB design?

A: No. The 0.10mm height reduction is within acceptable tolerance and does not impact PCB layout, component clearance, or assembly. This lower profile may provide a slight advantage in space-constrained applications.

Q5: Why is the original part marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status in Samsung's product portfolio. Existing inventory may be available, but the manufacturer does not recommend its use in new designs. The SPMWHT541MP5WAPKS4 is the active replacement offering improved performance and guaranteed long-term availability.

Q6: Is the ROHS3 compliance of the substitute better than the RoHS compliance of the original?

A: ROHS3 represents a more recent and stringent environmental compliance standard compared to the original RoHS designation. Both parts are environmentally compliant, but ROHS3 provides assurance of adherence to updated regulatory requirements.

Q7: Can the substitute handle higher current than the original part?

A: Yes. The substitute's maximum current rating is 180mA compared to 150mA for the original. However, both parts are tested and specified at 65mA. The higher maximum rating provides additional operational margin and design flexibility.

Q8: Will the improved efficiency of the substitute affect thermal management requirements?

A: The substitute's improved efficiency (167 lm/W versus 151 lm/W) and lower thermal resistance (15°C/W versus 16°C/W) result in reduced heat generation and improved thermal performance. Existing thermal management solutions designed for the original part will perform adequately with the substitute.

Q9: Are there any supply or lead time differences between these parts?

A: The substitute (SPMWHT541MP5WAPKS4) is in active production with significantly higher inventory availability (48,482 pieces) compared to the original part (764 pieces). This ensures reliable supply chain continuity and shorter lead times for new orders.

Q10: What is the base product number for both parts?

A: Both SPMWHT541MD5WAP0S2 and SPMWHT541MP5WAPKS4 share the base product number SPMWHT541, confirming they belong to the same product family and are designed for equivalent applications.
