Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MD5WAVHS1 is determined by strict alignment of the following parameters:

Critical Match Parameters (Non-Negotiable):

• Color Temperature: 3000K warm white
• Forward Voltage: 2.95V typical
• Viewing Angle: 120°
• Package Type: 5630 (4-SMD)
• Mounting Type: Surface Mount

Acceptable Variation Parameters:

• Luminous Flux: 25lm to 27lm range (specification tolerance)
• Test Current: 65mA reference point
• Maximum Current: May exceed 150mA if thermal design permits
• Thermal Resistance: Minor variations acceptable if within thermal budget
• CRI: May differ based on application requirements

The SPMWHT541MP7WAVMS0 qualifies as a direct substitute based on matching all critical parameters while offering enhanced specifications in maximum current rating (180mA vs 150mA) and improved thermal characteristics (15°C/W vs 16°C/W).

Parameter Comparison

Engineering Selection Recommendations

For Existing Production (SPMWHT541MD5WAVHS1 Replacement):

The SPMWHT541MP7WAVMS0 is the qualified substitute for the SPMWHT541MD5WAVHS1. Both components share identical electrical characteristics at the test point (2.95V, 65mA, 26lm, 120° viewing angle, 3000K color temperature) and are housed in compatible 5630 package formats.

The substitute offers measurable improvements:

• Enhanced maximum current rating (180mA vs 150mA) provides additional thermal margin
• Improved thermal resistance (15°C/W vs 16°C/W) reduces junction temperature rise
• Higher CRI rating (90 vs 80) delivers superior color rendering
• Lower seated height (0.80mm vs 0.90mm) maintains PCB clearance compatibility
• Active product status ensures continued availability and supply chain support

Compliance Considerations:

Both components meet RoHS requirements. The substitute carries ROHS3 certification, representing compliance with the current regulatory standard. Moisture sensitivity level (MSL 2A, 4 weeks) is identical, requiring equivalent handling and storage protocols.

Design Continuity:

Direct substitution is electrically and mechanically feasible without circuit modification. The identical forward voltage and test current ensure driver circuit compatibility. The 5630 package footprint match eliminates PCB redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAVMS0 replace SPMWHT541MD5WAVHS1 in existing designs without modification?

A: Yes. Both components operate at identical electrical specifications (2.95V forward voltage, 65mA test current, 26 lumens nominal output). The 5630 package footprint is compatible. No circuit changes are required.

Q: What is the difference between "Flat Lead Exposed Pad" and "Flat Leads" package configurations?

A: Both are 4-SMD 5630 packages with identical external dimensions (5.00mm x 3.00mm). The exposed pad variant provides enhanced thermal coupling to the PCB. The substitute's flat lead configuration remains mechanically and electrically compatible with standard 5630 footprints.

Q: Does the higher maximum current rating (180mA vs 150mA) affect circuit design?

A: No. The substitute's higher maximum current rating provides additional thermal headroom but does not require circuit modification. Existing driver circuits operating at 65mA test current remain fully compatible. The higher rating simply indicates greater design margin.

Q: Why does the substitute have a lower seated height (0.80mm vs 0.90mm)?

A: The 0.80mm height of SPMWHT541MP7WAVMS0 represents improved package design. This lower profile maintains compatibility with existing PCB layouts while reducing overall assembly height. No design changes are necessary.

Q: Is the CRI difference (90 vs 80) significant for my application?

A: CRI measures color rendering accuracy. The substitute's CRI of 90 provides superior color fidelity compared to the original's CRI of 80. For applications requiring accurate color representation (retail, hospitality, photography), the higher CRI is beneficial. For general illumination, both ratings are acceptable.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both components carry MSL 2A rating with 4-week floor life. Identical handling, storage, and reflow protocols apply to both parts.

Q: What is the significance of "Active" product status for the substitute?

A: Active status indicates Samsung continues manufacturing and supporting SPMWHT541MP7WAVMS0. The original part's "Not For New Designs" status reflects Samsung's transition away from that specific variant. The substitute ensures long-term supply chain continuity.

Q: Can I use SPMWHT541MP7WAVMS0 in applications originally designed for SPMWHT541MD5WAVHS1?

A: Yes. Electrical compatibility is complete at the 65mA operating point. Mechanical compatibility is confirmed through identical package dimensions and footprint. The substitute's enhanced specifications (higher maximum current, improved thermal resistance, higher CRI) make it suitable for all applications previously served by the original part.
