Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASMT-AB00-NMP00 is based on the following critical parameters:

Color & Wavelength Compatibility: Both the main part and substitute must emit blue light within the visible spectrum range. The ASMT-AB00-NMP00 operates at 465nm; substitutes must maintain blue wavelength characteristics suitable for the same application context.

Electrical Performance: Forward voltage (Vf), test current, and maximum current ratings must be compatible with existing circuit designs. The main part operates at 3.2V typical with 350mA test current and 500mA maximum current.

Luminous Output: Lumens per watt efficiency and absolute luminous flux determine brightness performance. The main part delivers 20 lm/W at test conditions.

Mounting & Package: Surface mount technology is required. Package form factor and pad configuration must be compatible with PCB layout and assembly equipment.

Regulatory Compliance: RoHS3 compliance and REACH status ensure environmental and regulatory alignment.

The ASM6-SBD3-NGJ0H qualifies as a substitute based on matching color (blue), compatible electrical parameters, surface mount capability, and equivalent regulatory compliance, despite differences in package form factor and enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ASM6-SBD3-NGJ0H is available as an active product from Broadcom Limited, addressing the supply discontinuation of the ASMT-AB00-NMP00. Both components are manufactured by the same supplier and maintain equivalent regulatory compliance (RoHS3, REACH Unaffected, EAR99 ECCN classification).

Selection of the ASM6-SBD3-NGJ0H requires verification that the following design parameter changes are acceptable:

Forward Voltage: The substitute operates at 2.9V typical versus 3.2V for the original part. Circuit designs dependent on specific voltage regulation or current limiting must be evaluated.

Package Form Factor: The substitute uses 1414 (3535 Metric) package versus 2-SMD gull wing exposed pad. PCB layout, thermal management, and assembly process compatibility must be confirmed.

Luminous Output: The substitute delivers significantly higher luminous flux (45lm versus 22lm) and efficiency (44.3 lm/W versus 20 lm/W) at identical test current. Applications sensitive to brightness levels require assessment.

Maximum Current Rating: The substitute supports 1A maximum current versus 500mA, providing additional operational headroom.

Frequently Asked Questions (FAQ)

Q: Can the ASM6-SBD3-NGJ0H directly replace the ASMT-AB00-NMP00 without circuit modification?

A: Direct replacement requires PCB layout compatibility with the 1414 package form factor and verification that the 2.9V forward voltage is acceptable within the circuit's current limiting design. The higher luminous output may require brightness adjustment in applications with fixed intensity requirements.

Q: What is the primary reason for substitution?

A: The ASMT-AB00-NMP00 is classified as Last Time Buy, indicating end-of-life status. The ASM6-SBD3-NGJ0H is an active product ensuring continued supply availability.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts maintain equivalent regulatory status: RoHS3 compliant, REACH unaffected, and EAR99 ECCN classification. No compliance barriers exist for substitution.

Q: How do the wavelength specifications compare?

A: The main part operates at 465nm (455nm ~ 475nm range), while the substitute operates at 470nm. Both fall within the blue spectrum and are suitable for applications requiring blue light emission.

Q: What are the thermal and mechanical considerations?

A: The substitute features a smaller footprint (3.46mm x 3.45mm versus 8.00mm diameter) and lower profile (2.10mm versus 4.20mm height). Thermal resistance specifications are not provided for the substitute; thermal management design must be re-evaluated for the new package.

Q: Is the higher efficiency of the substitute a concern?

A: The substitute delivers 44.3 lm/W versus 20 lm/W, resulting in higher brightness at equivalent current. Applications requiring specific luminous output levels must account for this performance increase through circuit design adjustments.
