Engineering Selection Recommendations

Primary Selection: SPMWH3228FD5WAVMSE

The SPMWH3228FD5WAVMSE maintains Active product status and is the preferred choice for new designs. This part offers the highest luminous efficiency at 133 lm/W and the lowest typical forward voltage at 3V, resulting in optimal power efficiency in LED lighting applications.

Substitute Selection Criteria:

The substitute parts SPMWH1228FD5WAV0S3, SPMWH1228FD5WAVMS3, and SPMWH1228FD5WAVUS3 are classified as "Not For New Designs" and are suitable only for replacement, legacy support, or continuation of existing production runs. These parts maintain electrical and mechanical compatibility with the primary part across all critical parameters.

Packaging Consideration:

The primary part packaging configuration is not specified in the provided data. The substitute parts are supplied in Tape & Reel (TR) packaging. Verify packaging requirements for your application before selection.

Compliance Status:

All parts maintain RoHS compliance and identical MSL ratings (2A, 4 Weeks), ensuring compatibility with standard surface-mount assembly processes and moisture-sensitive device handling protocols.

Forward Voltage Difference:

The substitute parts operate at 3.1V typical forward voltage compared to 3V for the primary part. This 0.1V difference is within normal LED operating tolerances and does not affect circuit compatibility in standard LED driver applications. Circuit designs must accommodate the specified forward voltage range of each part.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1228FD5WAVUS3 be used as a direct replacement for SPMWH3228FD5WAVMSE?

A: SPMWH1228FD5WAVUS3 meets all critical electrical and mechanical parameters including luminous flux, current ratings, viewing angle, CRI, package dimensions, and thermal characteristics. However, the substitute part carries "Not For New Designs" status. Use this part only for replacement applications or legacy product support.

Q: What is the difference between the three substitute parts?

A: SPMWH1228FD5WAV0S3, SPMWH1228FD5WAVMS3, and SPMWH1228FD5WAVUS3 are electrically and mechanically identical. The suffix designations (0S3, MS3, US3) indicate different regional packaging or supply chain configurations. All three parts are supplied in Tape & Reel packaging and meet identical performance specifications.

Q: Does the 0.1V forward voltage difference between the main part and substitutes affect circuit design?

A: The forward voltage difference (3V main part versus 3.1V substitutes) is within standard LED operating tolerances. Circuit designs using constant-current LED drivers accommodate this variation automatically. For voltage-regulated designs, verify that the power supply can deliver the required voltage across the specified forward voltage range.

Q: Are the substitute parts suitable for new product designs?

A: No. The substitute parts carry "Not For New Designs" product status. For new designs, use the primary part SPMWH3228FD5WAVMSE, which maintains Active status. Substitute parts are intended for replacement, repair, or continuation of existing products only.

Q: What is the inventory availability difference between the main part and substitutes?

A: The main part SPMWH3228FD5WAVMSE has 728 units in stock. Substitute parts have higher availability: SPMWH1228FD5WAV0S3 (2,401 units), SPMWH1228FD5WAVMS3 (3,758 units), and SPMWH1228FD5WAVUS3 (32,929 units). Higher inventory in substitute parts reflects their legacy status.

Q: Do all parts meet RoHS compliance requirements?

A: Yes. The main part and all substitute parts are RoHS Compliant and carry identical MSL ratings of 2A (4 Weeks), ensuring compatibility with standard surface-mount assembly and moisture-sensitive device handling procedures.

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

A: Yes, for replacement or continuation of existing products. All parts maintain identical luminous flux (60lm), current specifications (150mA test, 160mA maximum), viewing angle (120°), CRI (80), and physical dimensions (3.50mm x 2.80mm x 0.75mm). Verify packaging requirements and forward voltage tolerance in your specific circuit design before implementation.

Q: What packaging format are the substitute parts supplied in?

A: All substitute parts are supplied in Tape & Reel (TR) packaging. Confirm that your assembly process accommodates tape and reel format before ordering. The primary part packaging format is not specified in the provided data.
