Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASM3-SDD0-APQ0H is determined by the following critical parameters:

• Color: Red LED
• Mounting Type: Surface Mount
• Package Footprint: 3.45mm x 3.45mm (1414/3535 metric equivalent)
• Electrical Characteristics: Forward voltage 2.1V, test current 350mA, maximum current 700mA
• Optical Performance: Viewing angle 130°, luminous flux in the 380mW–480mW range
• Product Status: Active replacement required due to obsolescence

The ASM6-SDD0-AQR0H meets these substitution criteria as an active Broadcom Limited product with compatible electrical ratings, identical footprint dimensions, and equivalent optical specifications.

Engineering Selection Recommendations

The ASM6-SDD0-AQR0H is the direct substitute for the obsolete ASM3-SDD0-APQ0H. Selection is based on:

• Active Product Status: The ASM6-SDD0-AQR0H is an active product, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: The substitute meets ROHS3 and REACH requirements, supporting compliance obligations in regulated markets.
• Electrical Equivalence: Identical forward voltage (2.1V), test current (350mA), and maximum current (700mA) ensure direct circuit compatibility.
• Mechanical Compatibility: Identical footprint (3.45mm x 3.45mm) and comparable height (2.10mm vs. 2.15mm) permit direct PCB layout reuse.
• Optical Performance: Equivalent viewing angle (130°) and luminous flux within acceptable tolerance (450mW vs. 390mW nominal) maintain system performance.

Frequently Asked Questions (FAQ)

Q: Can the ASM6-SDD0-AQR0H be used as a direct replacement on existing PCBs designed for the ASM3-SDD0-APQ0H?

A: Yes. Both parts share identical footprint dimensions (3.45mm x 3.45mm), equivalent height specifications (2.10mm vs. 2.15mm maximum), and identical electrical characteristics (2.1V forward voltage, 350mA test current). No PCB redesign is required.

Q: What is the difference in luminous flux between these parts?

A: The ASM6-SDD0-AQR0H delivers 450mW nominal luminous flux compared to 390mW for the ASM3-SDD0-APQ0H. Both operate within their specified tolerance ranges at 25°C test temperature. The ASM6 variant provides approximately 15% higher output within normal operating conditions.

Q: Are there packaging differences between the main part and substitute?

A: The ASM6-SDD0-AQR0H is supplied in Tape & Reel (TR) packaging. Packaging format does not affect electrical or mechanical compatibility; it impacts only procurement and assembly logistics.

Q: Does the ASM6-SDD0-AQR0H meet environmental compliance standards?

A: Yes. The ASM6-SDD0-AQR0H is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in regulated markets.

Q: What is the Moisture Sensitivity Level (MSL) of the substitute part?

A: The ASM6-SDD0-AQR0H has an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
