Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MD5WAP0S3 is determined by strict alignment across the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must operate at White, Cool 6500K specification. This parameter is non-negotiable for color-matched applications.

Forward Voltage (Vf) and Test Current: The substitute must maintain 2.95V typical forward voltage at 65mA test current to ensure direct circuit compatibility without redesign of current-limiting resistor networks.

Package and Mounting Type: Both parts must use 4-SMD surface mount configuration with 5630 supplier device package designation. Physical dimensions (5.00mm × 3.00mm) and maximum seated height must remain within tolerance for PCB layout compatibility.

Viewing Angle: The 120° viewing angle specification must be preserved to maintain optical performance in the target application.

CRI and Lumens/Watt: Color rendering index of 80 and luminous efficacy baseline establish the photometric performance class.

Compliance Standards: RoHS status and MSL rating must meet or exceed the original specification to ensure manufacturing process compatibility and shelf-life requirements.

The SPMWHT541MP5WAPKS4 qualifies as a direct substitute based on matching all critical parameters while offering improved product status and enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

For Existing Production Lines: The SPMWHT541MD5WAP0S3 remains suitable for ongoing manufacturing of established products where design changes are not planned. Current inventory of 1036 pieces supports near-term production requirements.

For New Product Development: The SPMWHT541MP5WAPKS4 is the recommended selection. This part carries Active product status, indicating full manufacturer support and design-in eligibility. The substitute delivers measurable performance improvements: 2 lumens higher flux output (33 lm vs. 31 lm), 5 lm/W higher luminous efficacy (167 lm/W vs. 162 lm/W), and improved thermal resistance (15°C/W vs. 16°C/W). Maximum current rating increases from 150mA to 180mA, providing additional operational headroom. ROHS3 compliance exceeds the RoHS Compliant status of the main part.

For Supply Chain Continuity: The SPMWHT541MP5WAPKS4 demonstrates superior inventory availability (48482 pieces in stock vs. 1036 pieces), supporting long-term production commitments without supply interruption risk.

Electrical Compatibility: Both parts operate at identical forward voltage (2.95V) and test current (65mA), enabling direct substitution in existing circuit designs without modification to current-limiting resistor values or power supply specifications.

Mechanical Compatibility: Both parts use identical 5630 package footprint and 5.00mm × 3.00mm dimensions. The substitute's reduced seated height (0.80mm vs. 0.90mm) provides additional PCB design margin without requiring layout changes.

Frequently Asked Questions (FAQ)

Q: Can the SPMWHT541MP5WAPKS4 be used as a direct replacement for the SPMWHT541MD5WAP0S3 in existing designs?

A: Yes. Both parts share identical forward voltage (2.95V), test current (65mA), color specification (White, Cool 6500K), viewing angle (120°), and package footprint (5630, 5.00mm × 3.00mm). No circuit redesign is required. The substitute's higher flux output (33 lm vs. 31 lm) and improved thermal resistance (15°C/W vs. 16°C/W) represent performance enhancements within the same electrical operating envelope.

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

A: Both designations refer to 4-SMD surface mount configurations with 5630 package geometry. The terminology variation reflects minor manufacturing process differences between product generations. Electrical performance, thermal characteristics, and PCB footprint compatibility remain equivalent for substitution purposes.

Q: Why is the SPMWHT541MD5WAP0S3 marked "Not For New Designs"?

A: This status indicates the part has transitioned to mature production phase with limited new design activity. Manufacturers apply this designation to manage product portfolio focus and encourage migration to newer alternatives. The SPMWHT541MP5WAPKS4 (Active status) represents the current generation equivalent with enhanced specifications and guaranteed long-term availability.

Q: Are there any thermal management differences between these parts?

A: The SPMWHT541MP5WAPKS4 provides improved thermal performance with 15°C/W thermal resistance compared to 16°C/W for the main part. This 1°C/W improvement reduces junction temperature rise under identical operating conditions, extending component life and improving reliability margins. Both parts maintain identical MSL rating (2A, 4 Weeks) and RoHS compliance status.

Q: What is the impact of the higher maximum current rating (180mA vs. 150mA) on substitution?

A: The increased maximum current rating of the substitute provides additional operational headroom without affecting standard 65mA test current operation. Existing designs operating at 65mA test current experience no change in performance or reliability. The higher rating accommodates future design iterations requiring increased brightness without component replacement.

Q: Are both parts suitable for high-volume production?

A: The SPMWHT541MP5WAPKS4 is preferred for high-volume production due to Active product status and significantly higher inventory availability (48482 pieces vs. 1036 pieces). This ensures consistent supply, stable pricing, and manufacturer support throughout the production lifecycle.
