The substitute part CSMW-LWG0-NS0AE maintains all critical electrical parameters and mechanical form factor while transitioning from obsolete to active product status.

Parameter Comparison

Engineering Selection Recommendations

The CSMW-LWG0-NS0AE is the manufacturer-recommended substitute for the obsolete CSMW-LWG0-NSTAE. Both components share the same base product number (CSMW-L) and are manufactured by Broadcom Limited, indicating direct product line continuity.

Status Transition: The substitute part transitions from obsolete to active product status, ensuring long-term availability and supply chain continuity for new production and field replacement applications.

Compliance Alignment: Both parts maintain ROHS3 compliance and are specified within the same product family. The substitute part is designated as the manufacturer-recommended equivalent, confirming electrical and mechanical compatibility.

Packaging Consideration: The substitute part is supplied in Tape & Reel (TR) packaging format, which is standard for high-volume surface-mount assembly operations. The original part packaging format is not specified in the provided data.

Moisture Sensitivity: The substitute part specifies MSL 3 (168 Hours) compared to MSL 1 (Unlimited) for the original part. This represents a change in moisture handling requirements during storage and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the CSMW-LWG0-NS0AE directly replace the CSMW-LWG0-NSTAE in existing designs?

A: The CSMW-LWG0-NS0AE is the manufacturer-recommended substitute and shares the same base product number and 2835 package form factor. Both components are surface-mount devices with identical mechanical compatibility. The substitute is designated as the active replacement for the obsolete part.

Q: What is the difference in Moisture Sensitivity Level between these parts?

A: The original part specifies MSL 1 (Unlimited), while the substitute specifies MSL 3 (168 Hours). MSL 3 requires controlled storage conditions with a maximum floor life of 168 hours after moisture exposure. Assembly processes must account for this reduced moisture tolerance window.

Q: Are both parts automotive-grade qualified?

A: The original part is specified with AEC-Q101 automotive qualification. The substitute part data does not include explicit qualification information in the provided parameters. Confirmation of automotive-grade status for the substitute should be obtained from the manufacturer datasheet.

Q: What is the package designation for both parts?

A: Both parts use the 1113 (2835 Metric) surface-mount package. This is a standard 2835-sized LED package with dimensions of 3.50mm length x 2.80mm width x 0.90mm maximum seated height. The package designation ensures mechanical compatibility with existing PCB layouts and pick-and-place equipment.

Q: Is the substitute part available in the same packaging format as the original?

A: The original part packaging format is not specified in the provided data. The substitute part is supplied in Tape & Reel (TR) format, which is standard for automated surface-mount assembly. Packaging format compatibility should be confirmed with your assembly process requirements.

Q: What electrical parameters should be verified for circuit design compatibility?

A: The original part specifies 3.22V forward voltage (Vf) at 150mA test current, with a maximum current rating of 240mA. Detailed electrical specifications for the substitute part are not provided in the available data. Complete electrical parameter verification should be obtained from the manufacturer datasheet before final design implementation.
