Parameter Comparison

Engineering Selection Recommendations

Both the SPMWH3326MS7WAV3SD and SPMWH3326MS7WZV3SD are Active product status components manufactured by Samsung Semiconductor, Inc. Both parts are identical in all electrical performance parameters, mechanical specifications, and compliance certifications. Selection between these parts is based on inventory availability and supply chain requirements.

The SPMWH3326MS7WZV3SD substitute part provides higher inventory availability (1930 units versus 622 units) while maintaining complete parametric equivalence. Both components carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000) and moisture sensitivity specifications (MSL 2A, 4 Weeks).

For applications requiring the LM301D warm white LED in 3030 metric package format with 3000K color temperature, 90 CRI, and 120° viewing angle, either part number is suitable for direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Are SPMWH3326MS7WAV3SD and SPMWH3326MS7WZV3SD directly interchangeable?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. They share identical forward voltage (2.72V), luminous flux (29lm at 65mA), color temperature (3000K), CRI (90), package dimensions (3030 metric), and thermal characteristics (12°C/W). Direct substitution is supported without circuit modification.

Q: What are the key parameters that define substitution eligibility for this LED?

A: Substitution eligibility is determined by matching: LM301D series designation, 3000K color temperature with 3-step MacAdam ellipse specification, 29lm luminous flux at 65mA test current, 2.72V forward voltage, 90 CRI, 120° viewing angle, 1212 (3030 metric) package, surface mount mounting type, and 12°C/W thermal resistance. All parameters must match exactly.

Q: Can this LED be used in applications requiring different color temperatures?

A: No. The SPMWH3326MS7WAV3SD and SPMWH3326MS7WZV3SD are specified exclusively for 3000K warm white applications with 3-step MacAdam ellipse tolerance. Different color temperature requirements necessitate alternative part numbers.

Q: What is the significance of the 3-step MacAdam Ellipse specification?

A: The 3-step MacAdam ellipse defines the color temperature tolerance and consistency of the warm white output. This specification ensures that the LED maintains 3000K color temperature within defined chromaticity boundaries, critical for applications requiring consistent warm white appearance across production batches.

Q: Are there any differences in moisture sensitivity handling between these substitute parts?

A: No. Both SPMWH3326MS7WAV3SD and SPMWH3326MS7WZV3SD carry identical MSL 2A (4 Weeks) classification, requiring identical storage and handling protocols. Moisture sensitivity level, shelf life, and bake-out procedures are identical for both parts.

Q: What is the maximum current rating, and how does it relate to the 65mA test current?

A: The maximum current rating is 400mA. The 65mA test current is the standard operating point at which luminous flux (29lm) and efficiency (164 lm/W) are specified. The 400mA maximum rating defines the absolute upper limit for continuous operation; operation above 65mA will increase junction temperature and reduce luminous efficiency.

Q: Can these LEDs be used in series or parallel configurations?

A: The provided specifications do not include information regarding series or parallel configuration suitability. Circuit design decisions must be based on forward voltage matching (2.72V typical) and current distribution requirements specific to the application.

Q: What is the thermal resistance value, and why is it important?

A: Thermal resistance is 12°C/W, indicating the temperature rise per watt of power dissipated. This parameter is critical for thermal management calculations in high-density LED arrays or applications with elevated ambient temperatures. Higher junction temperatures reduce luminous output and lifespan.

Q: Are both parts available in the same packaging format?

A: Yes. Both SPMWH3326MS7WAV3SD and SPMWH3326MS7WZV3SD are supplied in Tape & Reel (TR) packaging format, suitable for automated pick-and-place assembly processes. Physical package dimensions (3030 metric, 0.118" x 0.118" x 0.030" max height) are identical.
