Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASMW-LR00-ASU0E is determined by the following critical parameters:

• Package Compatibility: Both parts must use the 1411 (3528 Metric) package format to ensure mechanical fit on PCB layouts
• Color and Wavelength: Red color specification with dominant wavelength in the 620nm to 635nm range maintains optical performance equivalence
• Electrical Characteristics: Test current of 150mA establishes the baseline operating condition for luminous output comparison
• Viewing Angle: 120° viewing angle must be maintained for indication applications
• Mounting Type: Surface mount configuration is required for compatibility with existing assembly processes
• Regulatory Compliance: ROHS3 compliance and MSL rating of 3 (168 Hours) must be preserved

The CSMW-LR00-ATV0E meets all substitution criteria and is classified as an active product with expanded electrical specifications and improved luminous efficiency.

Parameter Comparison

Engineering Selection Recommendations

The CSMW-LR00-ATV0E is the qualified substitute for the obsolete ASMW-LR00-ASU0E. Both components maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification) and equivalent moisture sensitivity ratings. The substitute part is currently in active production status with 6236 units available in inventory, compared to the limited stock of 849 units for the obsolete part.

The CSMW-LR00-ATV0E provides expanded electrical specifications including a maximum current rating of 200mA and documented forward voltage of 2.1V at test conditions, offering design flexibility for applications requiring higher brightness or current headroom. The luminous efficiency specification of 60 lm/W at test current provides quantified performance data not available for the original part.

Both parts are supplied by Broadcom Limited and share identical package geometry, wavelength characteristics, and viewing angle specifications, ensuring direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the CSMW-LR00-ATV0E be used as a direct replacement for the ASMW-LR00-ASU0E?

A: Yes. Both parts share identical package dimensions (1411/3528 Metric), wavelength specifications (623nm dominant / 622nm nominal), viewing angle (120°), test current (150mA), and regulatory compliance status. No circuit modifications are required.

Q: What is the difference in packaging between the two parts?

A: The ASMW-LR00-ASU0E is supplied in Cut Tape (CT) & Digi-Reel® format, while the CSMW-LR00-ATV0E is supplied in Tape & Reel (TR) format. Both formats are compatible with standard SMD assembly equipment.

Q: Are there electrical performance differences between these parts?

A: The CSMW-LR00-ATV0E provides additional electrical specifications including maximum current rating (200mA) and forward voltage (2.1V at 150mA test current). Both parts operate at identical test current (150mA) and maintain the same wavelength and viewing angle characteristics.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8541.41.0000. Moisture sensitivity level is 3 (168 Hours) for both components.

Q: Why is the original part classified as obsolete?

A: The ASMW-LR00-ASU0E is listed as obsolete by the manufacturer. The CSMW-LR00-ATV0E is the active equivalent part from Broadcom Limited and is recommended for all new designs and ongoing production requirements.
