Engineering Selection Recommendations

For Existing Designs (SPMWH3228FD5WAVMS2 Replacement):

The SPMWH3228FD5WAVMS2 is classified as "Not For New Designs." For production support and component continuity, the three substitute parts—SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, and SPMWH3228FD5WAVMSC—are direct parametric equivalents. All three substitute parts are Active status products from Samsung Semiconductor and maintain identical electrical and mechanical specifications with the following exceptions:

• Forward Voltage reduction from 3.1V to 3.0V (0.1V decrease)
• Efficiency improvement from 120 lm/W to 124 lm/W

Both variations fall within standard circuit design tolerance for LED applications and do not require design modification.

Compliance and Certification:

All substitute parts maintain RoHS Compliance and MSL 2A (4 Weeks) moisture sensitivity rating, ensuring compatibility with existing manufacturing and storage protocols.

Inventory Availability:

SPMWH3228FD5WAVMSC offers the highest inventory level (1096 Pcs), followed by SPMWH3228FD5WAVKSC (877 Pcs) and SPMWH3228FD5WAV0SC (737 Pcs).

Frequently Asked Questions (FAQ)

Q: Can SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, or SPMWH3228FD5WAVMSC be used as direct replacements for SPMWH3228FD5WAVMS2?

A: Yes. All three substitute parts are parametric equivalents with identical color temperature (3000K), luminous flux (56 lm at 25°C, 150mA), viewing angle (120°), package format (1113/2835 metric), and thermal characteristics. The forward voltage reduction (3.1V to 3.0V) and efficiency improvement (120 to 124 lm/W) are within acceptable design tolerance for LED circuits.

Q: What is the difference between the three substitute part numbers?

A: SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, and SPMWH3228FD5WAVMSC are all LM281BZ+ series parts with identical electrical and mechanical specifications. The differences in part number suffixes reflect Samsung's internal product tracking and packaging variants. All three are functionally equivalent for circuit design purposes.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three substitute parts (SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, SPMWH3228FD5WAVMSC) are RoHS Compliant and maintain MSL 2A (4 Weeks) moisture sensitivity rating, consistent with the original SPMWH3228FD5WAVMS2.

Q: Does the 0.1V forward voltage reduction affect circuit design?

A: No. The reduction from 3.1V to 3.0V typical forward voltage is a minor variation within standard LED circuit design tolerance. Existing current-limiting resistor or driver circuits will function without modification.

Q: What is the significance of the LM281BZ to LM281BZ+ series change?

A: The LM281BZ+ represents an active product line continuation from Samsung Semiconductor. The LM281BZ (original series) is not for new designs, while LM281BZ+ (substitute series) is active. This transition ensures long-term component availability and manufacturing support.

Q: Can these parts be used interchangeably in surface mount assembly?

A: Yes. All parts share identical package format (1113/2835 metric), mounting type (Surface Mount), and thermal resistance (25°C/W), ensuring compatibility with existing PCB layouts and reflow soldering processes.
