Key Parameters

Substitute Part Grouping Explanation

Substitution for the ASMT-JB11-NMP01 is determined by strict equivalence across the following critical parameters:

• Color and Wavelength: Blue 465nm (455nm ~ 475nm) range
• Electrical Performance: 350mA test current, 3.2V forward voltage, 500mA maximum current
• Optical Output: 29lm luminous flux at test conditions, 26 lm/W efficiency
• Mechanical Compatibility: 6-SMD flat lead exposed pad package, 4.00mm x 4.00mm footprint, 1.95mm maximum seated height
• Thermal Characteristics: 9°C/W thermal resistance
• Mounting: Surface mount configuration

The ASMT-JB11-NNQ01 meets all these criteria and is classified as a manufacturer-recommended substitute. The primary distinction between the main part and substitute is product status (obsolete vs. active) and packaging format (bulk vs. tape & reel), with no electrical or mechanical parameter deviations.

Parameter Comparison

Engineering Selection Recommendations

The ASMT-JB11-NNQ01 is the direct substitute for the obsolete ASMT-JB11-NMP01. Both parts share identical electrical, optical, and mechanical specifications. Selection of the substitute is justified by:

• Product Status: The ASMT-JB11-NNQ01 maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance: The substitute achieves ROHS3 compliance, meeting current environmental and regulatory requirements.
• Moisture Sensitivity: The substitute offers improved moisture handling with MSL 1 (unlimited shelf life) compared to MSL 2A (4 weeks), reducing storage and handling constraints.
• Packaging: Tape & reel packaging is standard for automated assembly processes and high-volume production environments.

No electrical or optical performance differences exist between the parts. Direct substitution is appropriate for all applications where the ASMT-JB11-NMP01 was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the ASMT-JB11-NNQ01 be used as a direct replacement for the ASMT-JB11-NMP01?

A: Yes. Both parts are electrically and mechanically identical. All critical parameters—wavelength, forward voltage, current ratings, luminous flux, viewing angle, and package dimensions—are equivalent. The substitute is the manufacturer-recommended replacement.

Q: What are the differences between the main part and substitute?

A: The primary differences are product status (obsolete vs. active), packaging format (bulk vs. tape & reel), moisture sensitivity level (MSL 2A vs. MSL 1), and RoHS compliance status (unspecified vs. ROHS3 compliant). No functional differences exist.

Q: Is the tape & reel packaging compatible with my assembly process?

A: Tape & reel is the standard packaging format for automated surface mount assembly. If your process uses manual or bulk component handling, reel packaging may require conversion or feeder compatibility. Consult your assembly equipment specifications.

Q: What is the significance of the improved MSL rating?

A: MSL 1 (unlimited shelf life) provides greater flexibility in storage and handling compared to MSL 2A (4-week limit). This reduces the risk of moisture absorption and associated solderability issues during extended storage or in humid environments.

Q: Are there any compliance or certification differences?

A: The substitute is ROHS3 compliant, meeting current environmental directives. Both parts carry REACH Unaffected and EAR99 ECCN classifications. The substitute's improved compliance status makes it suitable for applications with strict regulatory requirements.
