Substitute Part Grouping Explanation

Substitution of the ASMT-AB00-NMP01 is based on the following criteria:

Color Match: Both parts must emit blue light within the visible spectrum.

Wavelength Compatibility: The substitute wavelength must fall within or near the blue spectrum range (465nm reference for the main part, 470nm for the substitute). This 5nm difference is within acceptable tolerance for blue LED applications.

Electrical Parameters: Forward voltage (Vf) and test current must be compatible with existing circuit designs. The substitute operates at 2.9V Vf (versus 3.2V), which represents a 0.3V reduction and must be evaluated for circuit compatibility.

Luminous Output: The substitute delivers 45 lumens at 350mA test current, representing a 105% increase in luminous flux compared to the main part's 22 lumens.

Efficiency: The substitute achieves 44.3 lm/W versus the main part's 20 lm/W, indicating superior energy efficiency.

Mounting and Package: Both parts are surface mount components. The main part uses a 2-SMD Gull Wing Exposed Pad package (8.00mm diameter), while the substitute uses a 1414 (3535 Metric) package (3.46mm x 3.45mm). Package differences require PCB layout redesign.

Compliance: Both parts maintain RoHS3 compliance and EAR99 ECCN classification.

Parameter Comparison

Engineering Selection Recommendations

The ASM6-SBD3-NGJ0H is the manufacturer-recommended substitute for the obsolete ASMT-AB00-NMP01. Selection of this substitute is justified by the following factors:

Product Status: The main part is obsolete, necessitating transition to an active product. The substitute maintains active status with ongoing manufacturer support and availability.

Compliance Alignment: Both parts share EAR99 ECCN classification and HTSUS code 8541.41.0000, ensuring consistent regulatory treatment.

Electrical Compatibility Considerations: The substitute operates at 2.9V Vf compared to the main part's 3.2V. Circuit designs must accommodate this 0.3V reduction. The substitute supports higher maximum current (1A versus 500mA), providing additional operational margin.

Optical Performance: The substitute delivers superior luminous output (45lm versus 22lm) and efficiency (44.3 lm/W versus 20 lm/W) at identical test current (350mA). Viewing angle differs by 10° (130° versus 140°), which may impact application-specific requirements.

Package Transition: The substitute uses a smaller 1414 (3535 Metric) package versus the main part's 8.00mm diameter 2-SMD package. This requires PCB layout redesign and may reduce board space requirements.

Frequently Asked Questions (FAQ)

Q: Can the ASM6-SBD3-NGJ0H directly replace the ASMT-AB00-NMP01 without circuit modification?

A: Direct replacement requires circuit evaluation. The substitute's 2.9V Vf (versus 3.2V) necessitates current-limiting resistor recalculation. The higher maximum current rating (1A) is compatible with existing designs but does not eliminate the need for proper current limiting.

Q: What are the key differences between these two parts?

A: Primary differences include product status (obsolete versus active), package size and type (8.00mm 2-SMD versus 3.46mm x 3.45mm 1414), forward voltage (3.2V versus 2.9V), luminous output (22lm versus 45lm), and efficiency (20 lm/W versus 44.3 lm/W).

Q: Does the wavelength difference (465nm versus 470nm) affect application compatibility?

A: Both wavelengths fall within the blue spectrum. The 5nm difference is within standard blue LED classification. Application compatibility depends on specific color matching or spectral requirements of the end application.

Q: What PCB modifications are required for substitution?

A: The smaller package footprint (1414 versus 2-SMD 8.00mm) requires new PCB layout design. Trace routing, pad dimensions, and component spacing must be redesigned for the 3.46mm x 3.45mm footprint.

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

A: Both parts share EAR99 ECCN and HTSUS 8541.41.0000 classification. The main part specifies ROHS3 compliance; the substitute's RoHS status is not specified in the provided data.

Q: What is the impact of the 10° viewing angle difference?

A: The substitute has a 130° viewing angle versus the main part's 140°. This 10° reduction may affect applications requiring wide-angle light distribution. Application-specific optical requirements should be evaluated.
