Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASMT-MY04-NNP00 is determined by strict alignment of the following critical parameters:

• Color Temperature (CCT): Both parts must operate within the 3300K warm white range (2600K ~ 4000K tolerance band)
• Forward Voltage (Vf): Nominal 3.2V to ensure compatibility with existing circuit designs
• Package Configuration: TO-252-3 DPAK with identical lead count and thermal characteristics (10°C/W)
• Physical Dimensions: 8.50mm x 8.50mm footprint with 3.40mm maximum seated height for PCB assembly compatibility
• Viewing Angle: 110° optical specification for consistent light distribution
• Compliance Standards: ROHS3 and REACH compliance maintained across substitutes
• Mounting Type: Surface mount configuration unchanged

The ASMT-MY22-NMP00 meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The ASMT-MY22-NMP00 is the manufacturer-recommended substitute for the obsolete ASMT-MY04-NNP00. Both components maintain identical electrical specifications at test conditions (3.2V, 350mA, 3300K CCT) and share the same physical package footprint and thermal characteristics. Both parts carry ROHS3 and REACH compliance certifications, meeting regulatory requirements for new designs and legacy system replacements.

The ASMT-MY22-NMP00 features an increased maximum current rating (700mA versus 500mA), providing additional operational margin without affecting compatibility at standard test current levels. Both components are classified as obsolete, indicating limited future availability through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can ASMT-MY22-NMP00 be used as a direct replacement for ASMT-MY04-NNP00?

A: Yes. Both parts share identical forward voltage (3.2V), test current (350mA), color temperature (3300K), package configuration (TO-252-3 DPAK), physical dimensions (8.50mm x 8.50mm), and thermal resistance (10°C/W). No circuit modifications are required.

Q: What is the difference between these two parts?

A: The primary difference is the maximum current rating: ASMT-MY04-NNP00 is rated to 500mA maximum, while ASMT-MY22-NMP00 is rated to 700mA maximum. At standard operating conditions (350mA test current), both parts perform identically.

Q: Are there any compliance differences?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is maintained across the substitution.

Q: Does the package footprint differ between these parts?

A: No. Both use the TO-252-3 DPAK package with identical dimensions (0.335" x 0.335" / 8.50mm x 8.50mm) and maximum seated height (0.134" / 3.40mm). PCB layouts require no modification.

Q: What is the viewing angle specification?

A: Both parts specify a 110° viewing angle, ensuring consistent optical performance in lighting applications.
