Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAUMS0 be used as a direct replacement for SPMWHT541MP7WAUHS0?

A: Yes. Both parts are identical in electrical performance (2.95V forward voltage, 65mA test current, 26 lumens output), optical characteristics (3500K color temperature, 90 CRI, 120° viewing angle), and mechanical specifications (4-SMD flat leads, 5630 package, 5.00mm x 3.00mm dimensions). The primary difference is product status: SPMWHT541MP7WAUMS0 is Active while SPMWHT541MP7WAUHS0 is Not For New Designs.

Q: What is the difference between the 3500K and 3000K part groups?

A: The only difference is color temperature. The 3500K group (SPMWHT541MP7WAU0S0, SPMWHT541MP7WAUKS0, SPMWHT541MP7WAUMS0) and 3000K group (SPMWHT541MP7WAV0S0, SPMWHT541MP7WAVKS0, SPMWHT541MP7WAVMS0) share identical forward voltage, current ratings, flux output, CRI, viewing angle, and package dimensions. Selection depends on application color temperature requirements.

Q: Are there any thermal or electrical performance differences between substitute parts?

A: No. All parts maintain identical thermal resistance of 15°C/W, forward voltage of 2.95V, maximum current of 180mA, and lumens per watt efficiency of 136 lm/W at 65mA test current.

Q: What does the part number suffix variation indicate?

A: The suffix variations (HS0, US0, KS0, V0S0, VKS0, VMS0) indicate different manufacturing batches or tape reel configurations within the same electrical and optical specifications. All variants within each color temperature group are functionally equivalent.

Q: Which substitute part offers the best inventory availability?

A: SPMWHT541MP7WAUMS0 offers the highest inventory with 52,082 pieces in stock for 3500K applications. SPMWHT541MP7WAVMS0 provides 33,985 pieces for 3000K applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are RoHS compliant. SPMWHT541MP7WAUMS0 and SPMWHT541MP7WAVMS0 carry ROHS3 designation, representing the current compliance standard. Other substitutes carry standard RoHS compliance.

Q: Can these parts be used interchangeably in existing designs?

A: Parts within the same color temperature group (3500K or 3000K) are mechanically and electrically interchangeable. Cross-group substitution (3500K to 3000K or vice versa) requires design verification to confirm color temperature compatibility with application requirements.
