ASMT-MY22-NMP01 Equivalent & Substitute Parts

Part Overview

The ASMT-MY22-NMP01 is a warm white LED lighting component manufactured by Broadcom Limited, featuring a color temperature of 3300K within the range of 2600K to 4000K. This surface-mount device operates at 4V forward voltage with a 700mA test current, delivering 125 lumens at 25°C and 45 lumens per watt efficiency. The component is housed in a TO-252-3 DPAK package with a 120° viewing angle and is classified as obsolete product status.

Due to its obsolete classification, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASMT-MY22-NMP01 is determined by the following critical parameters:

Color and CCT Compatibility: The substitute part must provide warm white light output within the acceptable range of 2600K to 4000K. The ASM6-SWD1-NPSBH operates at 3000K, which falls within this range and maintains color consistency with the original component.

Electrical Performance: The substitute must operate within compatible voltage and current specifications. The ASM6-SWD1-NPSBH operates at 3V with a 350mA test current, representing a lower power requirement compared to the original 4V/700mA specification. This difference requires circuit-level evaluation for direct substitution.

Luminous Output: The substitute delivers 130 lumens at 25°C with improved efficiency of 124 lm/W, exceeding the original component's 125 lumens and 45 lm/W performance.

Viewing Angle: The substitute provides a 130° viewing angle, which exceeds the original 120° specification, offering broader light distribution.

Mounting and Package: Both components are surface-mount devices. The substitute uses a 1414 (3535 Metric) package, which differs from the original TO-252-3 DPAK package. This package change requires PCB layout modification.

Thermal Characteristics: The substitute exhibits superior thermal performance with 4°C/W thermal resistance compared to the original 10°C/W, enabling better heat dissipation.

Parameter Comparison

Engineering Selection Recommendations

The ASM6-SWD1-NPSBH is classified as an active product from Broadcom Limited, providing long-term availability and supply chain stability compared to the obsolete ASMT-MY22-NMP01. Both components share identical export classification (EAR99) and tariff codes (8541.41.0000), ensuring consistent regulatory compliance.

The substitute part delivers superior performance characteristics: higher luminous efficiency (124 lm/W versus 45 lm/W), improved thermal management (4°C/W versus 10°C/W), and specified color rendering index (80 CRI). The warm white color temperature of 3000K remains within the acceptable range for warm white applications.

Direct substitution requires circuit redesign due to differences in electrical specifications (3V/350mA versus 4V/700mA) and package geometry (1414 versus TO-252-3 DPAK). PCB layout modification is mandatory to accommodate the smaller 3535 metric footprint and different lead configuration.

Frequently Asked Questions (FAQ)

Q: Can the ASM6-SWD1-NPSBH be used as a direct drop-in replacement for the ASMT-MY22-NMP01?

A: No. While both are warm white surface-mount LEDs from Broadcom Limited, the substitute requires circuit-level modifications. The voltage and current specifications differ (3V/350mA versus 4V/700mA), and the package footprint is significantly smaller (1414 versus TO-252-3 DPAK). PCB redesign is necessary.

Q: Are the color temperatures compatible?

A: Yes. The substitute operates at 3000K, which falls within the acceptable warm white range of 2600K to 4000K specified for the original component. Both deliver warm white light output suitable for equivalent applications.

Q: What are the key advantages of the substitute part?

A: The ASM6-SWD1-NPSBH offers active product status ensuring long-term availability, superior luminous efficiency (124 lm/W), improved thermal performance (4°C/W), specified color rendering index (80 CRI), and higher maximum current rating (1A). The smaller package footprint enables more compact designs.

Q: Does the package size difference affect compatibility?

A: Yes. The substitute uses a 1414 (3535 Metric) package measuring 3.45mm x 3.45mm, compared to the original TO-252-3 DPAK at 8.50mm x 8.50mm. This requires complete PCB layout redesign and cannot be accommodated in existing footprints without modification.

Q: Are regulatory certifications equivalent?

A: Yes. Both components share identical export classification (EAR99) and tariff codes (8541.41.0000), ensuring equivalent regulatory compliance for international trade and procurement.

Q: What is the impact of the lower operating current?

A: The substitute operates at 350mA test current versus 700mA for the original. This requires driver circuit modification to deliver the correct forward voltage (3V) and current limiting. Existing 4V/700mA drive circuits cannot be used without redesign.
