Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWH3326MD7WAPYSA is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Color specification: White, Cool 6500K
• Package format: 1212 (3030 Metric) surface mount
• Forward voltage: 2.75V nominal
• Test current: 65 mA
• Viewing angle: 120°
• CRI: 90 minimum
• Thermal resistance: 12°C/W

Allowable Variation Range:

• Luminous flux @ 25°C: 26–29 lm (specification range tolerance)
• Lumens/Watt efficiency: within product line performance envelope
• Maximum current rating: 400 mA or higher
• Height seated: up to 0.75 mm (minor mechanical tolerance)

The substitute part SPMWH3326MP7WAPYS0 belongs to the LM301Z+ series and maintains all critical electrical parameters while offering improved luminous flux performance (30 lm vs. 28 lm) and higher efficiency (168 lm/W vs. 157 lm/W). Both parts share identical package geometry, thermal characteristics, and color specifications, enabling direct functional substitution in circuit designs.

Engineering Selection Recommendations

Primary Substitute: SPMWH3326MP7WAPYS0

The SPMWH3326MP7WAPYS0 is the direct functional equivalent for the obsolete SPMWH3326MD7WAPYSA. Selection is based on the following engineering criteria:

Product Status Alignment: The substitute part carries Active product status, ensuring continued availability and supply chain stability. The main part is classified as Obsolete, necessitating transition to an alternative.

Electrical Parameter Equivalence: Both parts operate at identical forward voltage (2.75V), test current (65 mA), and maximum current rating (400 mA). Color temperature, CRI, and viewing angle specifications are identical, ensuring optical and photometric compatibility.

Mechanical Compatibility: Both components use the 1212 (3030 Metric) surface mount package with identical footprint dimensions (3.00 mm × 3.00 mm). The seated height difference of 0.15 mm (0.60 mm vs. 0.75 mm) falls within standard PCB assembly tolerances and does not affect reflow soldering or component placement.

Thermal Characteristics: Thermal resistance remains constant at 12°C/W, maintaining thermal management performance in existing circuit designs.

Performance Enhancement: The substitute part delivers improved luminous flux (30 lm vs. 28 lm) and higher luminous efficacy (168 lm/W vs. 157 lm/W), providing measurable performance gains without requiring circuit redesign.

Compliance and Certifications: Both parts maintain identical MSL rating (2A, 4 Weeks), ECCN classification (EAR99), and HTSUS code (8541.41.0000). The substitute part carries RoHS Compliant certification, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SPMWH3326MP7WAPYS0 be used as a direct replacement for SPMWH3326MD7WAPYSA in existing designs?

A: Yes. Both parts share identical electrical specifications (2.75V forward voltage, 65 mA test current, 120° viewing angle, 90 CRI, 6500K color temperature) and package geometry (3030 metric, 3.00 mm × 3.00 mm footprint). No circuit modifications are required. The substitute part offers higher luminous flux (30 lm vs. 28 lm) and efficiency (168 lm/W vs. 157 lm/W).

Q: What is the significance of the height difference between these parts?

A: The main part has a seated height of 0.60 mm, while the substitute measures 0.75 mm. This 0.15 mm difference is within standard PCB assembly tolerances and does not affect reflow soldering, component placement accuracy, or clearance in typical applications. Both parts are compatible with standard 3030 package assembly processes.

Q: Why is the main part classified as Obsolete?

A: The SPMWH3326MD7WAPYSA is marked as Obsolete, indicating Samsung Semiconductor has discontinued production. The LM301Z+ series (represented by SPMWH3326MP7WAPYS0) represents the current production equivalent with improved performance characteristics.

Q: Are there any packaging differences between these parts?

A: The main part is supplied in standard packaging, while the substitute (SPMWH3326MP7WAPYS0) is packaged in Tape & Reel (TR) format. Both use identical component specifications and are suitable for automated assembly processes. Tape & Reel packaging is standard for high-volume production environments.

Q: What parameters must remain constant for substitution to be valid?

A: The following parameters must match exactly: color temperature (6500K), CRI (90), forward voltage (2.75V), test current (65 mA), viewing angle (120°), package format (1212/3030 metric), and thermal resistance (12°C/W). Luminous flux and efficiency may vary within the product line specification range.

Q: Is the substitute part RoHS compliant?

A: Yes. The SPMWH3326MP7WAPYS0 carries RoHS Compliant certification. Both parts maintain identical MSL rating (2A, 4 Weeks) and ECCN classification (EAR99), meeting current regulatory and export control requirements.

Q: Can these parts be mixed in the same production batch?

A: Yes. Both parts are electrically and mechanically compatible and can be used interchangeably in the same circuit design. However, due to the slight luminous flux difference (28 lm vs. 30 lm), applications requiring strict luminous output uniformity across all units should maintain consistent sourcing from a single part number per production lot.
