ASMT-MY22-NMP00 Equivalent & Substitute Parts

Part Overview

The ASMT-MY22-NMP00 is a Moonstone® White warm white LED (3300K) manufactured by Broadcom Limited in TO-252-3 DPAK surface mount package. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The part delivers 100lm at 25°C with a forward voltage of 3.2V at 350mA test current, suitable for general illumination applications requiring warm white color temperature.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASMT-MY22-NMP00 is determined by the following critical parameters:

Color Temperature Compatibility: Warm white LEDs in the 3000K–3300K range are functionally equivalent for applications requiring warm white illumination.

Luminous Flux Performance: Substitute parts must deliver comparable light output at the specified test current (350mA) to maintain system brightness requirements.

Electrical Characteristics: Forward voltage (Vf) and maximum current ratings must be compatible with existing circuit designs. The ASMT-MY22-NMP00 operates at 3.2V typical; substitutes operating at 3.0V are acceptable within standard LED tolerance ranges.

Mounting and Package: Surface mount technology is required. Package footprint differences (TO-252-3 DPAK vs. 1414 metric) require PCB redesign but do not prevent functional substitution.

Thermal Performance: Thermal resistance values affect heat dissipation capability. Lower thermal resistance (4°C/W vs. 10°C/W) indicates improved thermal management in substitute parts.

Compliance and Status: Active product status ensures ongoing availability and supply chain reliability compared to obsolete parts.

Parameter Comparison

Engineering Selection Recommendations

The ASM6-SWD1-NPSBH is a direct functional substitute for the obsolete ASMT-MY22-NMP00 based on the following engineering criteria:

Product Status: The ASM6-SWD1-NPSBH carries active product status, ensuring long-term availability and supply chain continuity. The ASMT-MY22-NMP00 is obsolete and subject to discontinuation.

Color Temperature Alignment: Both parts deliver warm white illumination within acceptable tolerance ranges (3300K vs. 3000K). The 300K difference falls within standard warm white classification and is imperceptible in typical lighting applications.

Electrical Compatibility: Forward voltage differs by 0.2V (3.2V vs. 3.0V), which is within standard LED operating tolerances and compatible with existing driver circuits designed for warm white LEDs.

Luminous Flux Performance: The ASM6-SWD1-NPSBH delivers 130lm at 350mA test current, representing a 30% improvement over the ASMT-MY22-NMP00 (100lm). This enhanced output maintains or exceeds system brightness requirements.

Efficiency Gain: Lumens per watt increases from 89 lm/W to 124 lm/W, indicating superior energy efficiency in the substitute part.

Thermal Management: Thermal resistance improves from 10°C/W to 4°C/W, providing better heat dissipation and extended operational life under sustained current conditions.

Compliance: Both parts are manufactured by Broadcom Limited. The ASMT-MY22-NMP00 is ROHS3 compliant; compliance status for the ASM6-SWD1-NPSBH is not specified in the provided data.

Package Consideration: The ASM6-SWD1-NPSBH uses a smaller 1414 (3535 metric) package compared to the TO-252-3 DPAK of the main part. PCB layout redesign is required for this substitution.

Frequently Asked Questions (FAQ)

Q: Can the ASM6-SWD1-NPSBH directly replace the ASMT-MY22-NMP00 without circuit modification?

A: Electrical substitution is possible due to compatible forward voltage (3.0V vs. 3.2V) and identical test current (350mA). However, package geometry differs significantly (1414 vs. TO-252-3 DPAK), requiring PCB footprint redesign and layout changes.

Q: What is the significance of the color temperature difference (3300K vs. 3000K)?

A: Both values fall within the warm white classification range. The 300K difference is not perceptible to human vision in typical lighting applications and does not affect functional compatibility for warm white illumination purposes.

Q: Why does the ASM6-SWD1-NPSBH deliver higher luminous flux (130lm vs. 100lm)?

A: The substitute part represents a newer generation LED technology with improved phosphor efficiency and die design, resulting in higher light output at the same test current.

Q: Is the smaller package size of the ASM6-SWD1-NPSBH an advantage?

A: The 1414 (3535 metric) package is significantly smaller (3.45mm x 3.45mm vs. 8.50mm x 8.50mm) and lower profile (2.10mm vs. 3.40mm). This enables more compact PCB designs and improved thermal performance due to lower thermal resistance (4°C/W vs. 10°C/W).

Q: What are the implications of the higher maximum current rating (1A vs. 700mA)?

A: The ASM6-SWD1-NPSBH supports higher current operation, providing design flexibility for applications requiring increased brightness or overdrive capability. Existing circuits operating at 350mA are unaffected.

Q: Are there any compliance or certification differences between the two parts?

A: The ASMT-MY22-NMP00 is confirmed ROHS3 compliant. Compliance status for the ASM6-SWD1-NPSBH is not specified in the provided technical data.
