Engineering Selection Recommendations

Primary Substitutes (3500K Color Temperature Match):

For direct replacement maintaining identical color temperature specification, select from:

SPMWHT541MP7WAUMS0: Active status with highest inventory (52,082 pcs). ROHS3 compliant. Recommended for new production designs requiring long-term supply assurance.
SPMWHT541MP7WAUKS0: Active status with 823 pcs inventory. RoHS compliant. Suitable for immediate procurement needs.
SPMWHT541MP7WAU0S0: Active status with 985 pcs inventory. RoHS compliant. Alternative option for 3500K applications.

Alternative Substitutes (3000K Color Temperature):

For applications where 3000K warm white is acceptable as an alternative:

SPMWHT541MP7WAVMS0: Active status with highest inventory (33,985 pcs). ROHS3 compliant. Recommended for designs permitting color temperature flexibility.
SPMWHT541MP7WAVKS0: Active status with 1,142 pcs inventory. RoHS compliant.
SPMWHT541MP7WAV0S0: Active status with 1,049 pcs inventory. RoHS compliant.

Compliance Consideration:

All substitute parts maintain RoHS compliance. Parts designated ROHS3 compliant (SPMWHT541MP7WAUMS0 and SPMWHT541MP7WAVMS0) represent the latest compliance certification and are preferred for new designs subject to evolving regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAUMS0 be used as a direct replacement for SPMWHT541MP7WAUNS0?

A: Yes. SPMWHT541MP7WAUMS0 is a parametric equivalent maintaining all electrical specifications (2.95V forward voltage, 65mA test current, 26lm flux, 136 lm/W efficiency, 90 CRI, 120° viewing angle) and mechanical specifications (5630 package, 5.00mm x 3.00mm dimensions, 0.80mm height, 15°C/W thermal resistance). The primary difference is product status (active vs. obsolete) and packaging format (Tape & Reel vs. bulk). No circuit modifications are required.

Q: What is the difference between 3500K and 3000K substitute options?

A: Color Correlated Temperature (CCT) differs: 3500K produces a warmer white appearance compared to 3000K. All other electrical and mechanical parameters remain identical. Selection depends on application lighting requirements. If the original design specifies 3500K for color rendering or aesthetic purposes, use 3500K substitutes (SPMWHT541MP7WAUMS0, SPMWHT541MP7WAUKS0, or SPMWHT541MP7WAU0S0). If 3000K is acceptable, 3000K options provide higher inventory availability.

Q: Are Tape & Reel packaged parts compatible with existing assembly processes?

A: Yes. Tape & Reel (TR) format is the standard production packaging for 5630 surface mount LEDs and is compatible with automated pick-and-place equipment. No process modifications are required. Tape specifications conform to industry standards for 5630 component packaging.

Q: What is the significance of ROHS3 compliance versus RoHS compliance?

A: ROHS3 represents the latest RoHS directive compliance certification (RoHS 3 / Directive 2015/863/EU), which includes additional restricted substances beyond the original RoHS specification. Parts marked ROHS3 compliant (SPMWHT541MP7WAUMS0 and SPMWHT541MP7WAVMS0) meet current and anticipated regulatory requirements. Both RoHS and ROHS3 compliant parts are acceptable; ROHS3 is preferred for designs with extended product lifecycles.

Q: Which substitute part offers the best supply continuity?

A: SPMWHT541MP7WAUMS0 provides the highest inventory (52,082 pcs) and active product status, ensuring long-term availability. SPMWHT541MP7WAVMS0 offers the second-highest inventory (33,985 pcs) for 3000K applications. Both parts are ROHS3 compliant, indicating manufacturer commitment to ongoing production support.

Q: Can multiple substitute parts be used interchangeably within the same design?

A: Yes, provided color temperature consistency is maintained. For uniform lighting output, use either all 3500K parts (SPMWHT541MP7WAUMS0, SPMWHT541MP7WAUKS0, SPMWHT541MP7WAU0S0) or all 3000K parts (SPMWHT541MP7WAVMS0, SPMWHT541MP7WAVKS0, SPMWHT541MP7WAV0S0). Mixing 3500K and 3000K parts in the same application results in visible color temperature variation.

Q: What is the Moisture Sensitivity Level (MSL) requirement?

A: All parts are classified as MSL 2A with a 4-week floor life. This indicates moderate moisture sensitivity requiring standard dry storage conditions and handling procedures. Components must be stored in moisture-controlled environments and used within 4 weeks of package opening under standard conditions.
