Key Parameters

Substitute Part Grouping Explanation

Substitution for the ASMT-AR30-ARS00 is determined by the following critical parameters:

Electrical Compatibility:

• Color: Red
• Wavelength range: 625nm to 628nm (within red spectrum)
• Forward voltage: 2.1V typical
• Test current: 350mA
• Maximum current: 700mA

Mechanical Compatibility:

• Mounting type: Surface Mount
• Package style: 2-SMD, Gull Wing configuration
• Height seated maximum: 0.165" (4.20mm)
• Viewing angle: 140°

Regulatory & Environmental:

• RoHS3 compliance
• ECCN: EAR99
• HTSUS: 8541.41.0000

The ASMT-AR30-AST00 qualifies as a direct substitute based on matching electrical parameters, compatible package configuration, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The ASMT-AR30-AST00 is the manufacturer-recommended substitute for the obsolete ASMT-AR30-ARS00. Both parts share identical electrical operating parameters (350mA test current, 2.1V forward voltage, 700mA maximum current) and mechanical compatibility (2-SMD Gull Wing package, 4.20mm seated height, 140° viewing angle).

The ASMT-AR30-AST00 carries a Last Time Buy status, indicating limited availability. The wavelength difference (625nm vs. 628nm) remains within the red spectrum and does not affect functional compatibility in standard applications. The luminous flux output of the substitute (60lm) falls within the specified range (52lm ~ 87lm) of the original part.

Moisture sensitivity level differs between the two parts (MSL 2 vs. 2A), requiring attention to storage and handling procedures during manufacturing. The substitute part requires more stringent moisture control (4-week shelf life vs. 1-year shelf life).

Frequently Asked Questions (FAQ)

Q: Can the ASMT-AR30-AST00 directly replace the ASMT-AR30-ARS00 in existing designs?

A: Yes. Both parts operate at identical test current (350mA), forward voltage (2.1V), and maximum current (700mA). The 2-SMD Gull Wing package configuration and 4.20mm seated height are identical, ensuring PCB layout compatibility without modification.

Q: What is the wavelength difference between these parts?

A: The main part operates at 628nm (620nm ~ 635nm range), while the substitute operates at 625nm. Both wavelengths fall within the red spectrum and are functionally equivalent for standard red LED applications.

Q: How does the luminous flux difference affect performance?

A: The main part delivers 70lm at test conditions, while the substitute delivers 60lm. Both values fall within the specified range of 52lm ~ 87lm. The substitute exhibits slightly lower efficiency (82 lm/W vs. 95 lm/W), but remains within acceptable parameters for red LED applications.

Q: What are the moisture sensitivity implications?

A: The main part (MSL 2) has a 1-year shelf life under controlled conditions. The substitute (MSL 2A) has a 4-week shelf life. Stricter moisture control and more frequent reflow processing are required for the substitute part to prevent moisture-induced failures.

Q: Are both parts RoHS compliant?

A: The main part is ROHS3 compliant. RoHS compliance status for the substitute part is not specified in the provided data.

Q: What is the difference between the package descriptions?

A: The main part specifies "2-SMD, Gull Wing Exposed Pad," while the substitute specifies "2-SMD, Gull Wing." Both are surface mount packages with identical mechanical dimensions and electrical performance. The exposed pad designation on the main part does not affect substitution compatibility.
