Engineering Selection Recommendations

The S1WM-3030408006-0000003S-00001 manufactured by Seoul Semiconductor Inc. is a direct substitute for the obsolete SPMWH3326FD3GBT0SA. Selection is based on the following engineering criteria:

Product Status: The substitute part carries Active product status, ensuring long-term availability and supply chain continuity. The original part is classified as Obsolete, making substitution necessary for ongoing production.

Electrical Compatibility: Both parts operate at identical forward voltage (6.2V) and test current (150mA). The substitute part provides higher maximum current rating (250mA vs. 200mA), offering improved operational margin. Luminous flux at 25°C and test current (141lm) falls within the acceptable range of the original specification (137–147lm).

Optical Characteristics: Both parts deliver neutral white 4000K color temperature with 120° viewing angle. The substitute part provides enhanced CRI of 80 compared to the original 70, resulting in improved color rendering without affecting spectral compatibility. Lumens/Watt efficiency is equivalent or superior (154 lm/W vs. 153 lm/W).

Mechanical Compatibility: Package dimensions, mounting type, and footprint are identical (1212/3030 Metric, 3.00mm × 3.00mm). Height variance (0.80mm vs. 0.60mm) remains within acceptable PCB assembly tolerances for surface-mount applications.

Thermal Performance: Thermal resistance of the substitute (17°C/W) is higher than the original (12°C/W) by 5°C/W. This variance is acceptable for applications operating within the specified current range and does not preclude direct substitution in standard thermal environments.

Compliance: The substitute part is ROHS3 compliant, meeting current environmental and regulatory requirements. Both parts share identical MSL rating (2A, 4 Weeks) and packaging format (Cut Tape).

Frequently Asked Questions (FAQ)

Q: Can the S1WM-3030408006-0000003S-00001 be used as a direct replacement without PCB modifications?

A: Yes. The substitute part maintains identical footprint, package dimensions (1212/3030 Metric), and electrical characteristics (6.2V, 150mA). No PCB layout changes are required. The 0.20mm height difference (0.80mm vs. 0.60mm) is within standard surface-mount assembly tolerances and does not affect reflow soldering or component placement.

Q: What is the significance of the 3-Step MacAdam Ellipse specification on the substitute part?

A: The 3-Step MacAdam Ellipse defines color consistency tolerance around the 4000K nominal CCT. This specification ensures tighter color uniformity across production batches compared to the original part, which does not specify MacAdam ellipse limits. Both parts deliver 4000K neutral white color and are optically compatible.

Q: Does the higher CRI (80 vs. 70) of the substitute part affect compatibility?

A: No. Higher CRI indicates improved color rendering capability and is a performance enhancement. The substitute part maintains identical color temperature (4000K) and viewing angle (120°), ensuring optical compatibility. Applications requiring the original CRI of 70 will function correctly with the substitute's CRI of 80.

Q: Why is the thermal resistance of the substitute part higher (17°C/W vs. 12°C/W)?

A: Thermal resistance variance reflects differences in package material composition and internal thermal pathways between manufacturers. The 5°C/W difference is acceptable for standard operating conditions at 150mA test current. Applications with thermal constraints should verify junction temperature calculations using the substitute's thermal resistance value.

Q: Are there any supply chain or lead time advantages to using the substitute part?

A: The substitute part carries Active product status with 2495 units in stock, compared to the Obsolete original part. Active status ensures continued availability and standard lead times. The original part, though currently in stock (27898 units), will eventually reach end-of-life with no replenishment.

Q: Can the substitute part handle the maximum current rating of the original (200mA)?

A: Yes. The substitute part is rated for 250mA maximum current, exceeding the original 200mA specification. Operation at 200mA is well within the substitute's safe operating range.

Q: What packaging formats are available for the substitute part?

A: The substitute part is supplied in Cut Tape (CT) format, matching the original packaging. This ensures compatibility with standard pick-and-place assembly equipment and tape-and-reel handling systems.

Q: Is the substitute part RoHS compliant?

A: Yes. The S1WM-3030408006-0000003S-00001 is ROHS3 compliant. RoHS compliance status is not specified for the original part. The substitute meets current environmental regulations for restricted substances.
