Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASMT-MYB4-NNP01 is determined by strict alignment of the following critical parameters:

• Color temperature: Warm white 3300K (2600K ~ 4000K range)
• Forward voltage: 3.2V typical
• Package configuration: TO-252-3 DPAK (2 Leads + Tab), SC-63
• Mounting type: Surface mount
• Viewing angle: 110°
• Physical dimensions: 0.335" L x 0.335" W (8.50mm x 8.50mm)
• Thermal resistance: 10°C/W
• Compliance: ROHS3 compliant

The ASMT-MY22-NMP00 meets all critical substitution criteria within the Moonstone® series, maintaining identical package geometry, color temperature specification, and thermal characteristics. Both components share the same base product platform and are manufactured by Broadcom Limited.

Parameter Comparison

Engineering Selection Recommendations

The ASMT-MY22-NMP00 is a direct functional equivalent for the obsolete ASMT-MYB4-NNP01. Both components maintain identical electrical specifications at test current (350mA, 3.2V), package geometry, and thermal characteristics. The ASMT-MY22-NMP00 demonstrates higher maximum current rating (700mA versus 350mA) and improved luminous flux performance (100lm at 25°C versus unspecified for the original), providing enhanced operational margin without compromising compatibility.

Both parts are ROHS3 compliant and manufactured by Broadcom Limited within the Moonstone® product series. The substitute part is currently available in inventory (1034 units) and packaged in tube format, supporting production requirements for applications requiring warm white 3300K LED lighting in TO-252-3 DPAK configuration.

Frequently Asked Questions (FAQ)

Q: Can ASMT-MY22-NMP00 be used as a direct replacement for ASMT-MYB4-NNP01?

A: Yes. Both components share identical forward voltage (3.2V), test current (350mA), color temperature (3300K warm white), package configuration (TO-252-3 DPAK), physical dimensions (8.50mm x 8.50mm), and thermal resistance (10°C/W). The substitute part is electrically and mechanically compatible for direct substitution in existing designs.

Q: What is the difference in maximum current rating between these parts?

A: The ASMT-MYB4-NNP01 has a maximum current rating of 350mA, while the ASMT-MY22-NMP00 is rated for 700mA maximum current. This difference does not affect substitution when operating at the specified test current of 350mA.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and REACH unaffected. The primary difference is moisture sensitivity level: ASMT-MYB4-NNP01 is MSL 2 (1 Year), while ASMT-MY22-NMP00 is MSL 4 (72 Hours). This affects storage and handling requirements but does not impact functional compatibility.

Q: What is the viewing angle specification for these LEDs?

A: Both the ASMT-MYB4-NNP01 and ASMT-MY22-NMP00 have a 110° viewing angle, ensuring identical light distribution characteristics in optical assemblies.

Q: Can these parts be used interchangeably in PCB layouts?

A: Yes. Both components use the TO-252-3 DPAK package with identical footprint dimensions (0.335" x 0.335", 8.50mm x 8.50mm) and maximum seated height (0.134", 3.40mm). No PCB layout modifications are required for substitution.
