Engineering Selection Recommendations

Primary Substitute: SPMWH3326MP5WARYS0

The SPMWH3326MP5WARYS0 is the direct functional equivalent for the obsolete SPMWH3326MD5WARYSA. Selection of this substitute is based on the following engineering criteria:

Product Status: The substitute carries Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete main part.

Electrical Compatibility: Both components operate at identical forward voltage (2.75V) and test current (65mA), with flux output within acceptable tolerance (36 lm vs. 35 lm nominal). The substitute demonstrates improved efficiency at 201 lm/W versus 196 lm/W.

Mechanical Compatibility: Both parts utilize the identical 1212 (3030 Metric) surface mount package with matching footprint dimensions (3.00 mm × 3.00 mm). The substitute height of 0.75 mm maximum is within acceptable PCB assembly clearance for standard reflow processes.

Regulatory Compliance: The substitute carries RoHS Compliant certification, meeting current environmental and regulatory requirements. Both components share identical thermal resistance (12°C/W) and moisture sensitivity classification (2A, 4 Weeks).

Enhanced Specifications: The substitute offers a maximum current rating of 400 mA compared to 200 mA, providing design margin for dynamic current applications without compromising thermal performance.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, standard for high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can SPMWH3326MP5WARYS0 be used as a direct drop-in replacement for SPMWH3326MD5WARYSA?

A: Yes. Both components share identical electrical characteristics (2.75V forward voltage, 65mA test current, 5000K color temperature, 120° viewing angle) and mechanical specifications (1212/3030 package, 3.00 mm × 3.00 mm footprint). The substitute is compatible with existing PCB layouts and reflow profiles. The 0.15 mm height difference (0.75 mm vs. 0.60 mm) does not affect assembly or performance.

Q: What is the flux output difference between the main part and substitute?

A: The main part delivers 35 lm nominal (33–36 lm range) at 25°C under 65mA test current. The substitute delivers 36 lm nominal (34–38 lm range) under identical conditions. This 1 lm difference falls within normal manufacturing tolerance and is not perceptible in lighting applications.

Q: Why is the substitute rated for 400 mA maximum current versus 200 mA?

A: The LM301Z+ series (substitute) incorporates enhanced thermal management and junction design compared to the LM301Z series (main part). The higher current rating reflects improved die architecture while maintaining identical thermal resistance (12°C/W). Operation at 65 mA test current remains unchanged.

Q: Is the substitute RoHS compliant?

A: Yes. The SPMWH3326MP5WARYS0 carries RoHS Compliant certification. The main part does not specify RoHS status. Both components meet identical moisture sensitivity requirements (2A, 4 Weeks).

Q: What is the difference between the LM301Z and LM301Z+ series?

A: The LM301Z+ represents an enhanced version of the LM301Z series with improved efficiency (201 lm/W vs. 196 lm/W), higher maximum current capability (400 mA vs. 200 mA), and Active product status. Color temperature, forward voltage, viewing angle, and package format remain identical.

Q: Are there packaging format differences?

A: The main part packaging format is not specified in available data. The substitute is supplied in Tape & Reel (TR) format, standard for automated assembly. Both components use the 1212 (3030 Metric) surface mount package.

Q: What is the inventory status for each part?

A: The main part (SPMWH3326MD5WARYSA) has 812 pieces in stock with Obsolete status. The substitute (SPMWH3326MP5WARYS0) has 862 pieces in stock with Active status, indicating ongoing production and supply availability.
