Substitute Part Grouping Explanation

Substitution of the CSMW-LWG0-NSTEE is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Color specification: White, Neutral 4500K
• Forward voltage range: 3.22V nominal
• Test current: 150mA
• Maximum current rating: 240mA
• Luminous flux output: 59lm at 25°C
• Efficiency: 122 lm/W at test current

Mechanical Compatibility:

• Package type: 1113 (2835 Metric)
• Mounting: Surface Mount
• Physical dimensions: 3.50mm x 2.80mm length and width
• Maximum seated height: 0.90mm

Compliance & Certification:

• Automotive grade qualification: AEC-Q101
• RoHS3 compliance
• Manufacturer: Broadcom Limited (same product family)

The substitute part CSMW-LWG0-NS0EE maintains electrical output specifications, package geometry, and automotive-grade certification while transitioning from obsolete to active product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CSMW-LWG0-NS0EE

The CSMW-LWG0-NS0EE is the manufacturer-recommended substitute for the obsolete CSMW-LWG0-NSTEE. Both parts share the same base product number (CSMW-L) and are manufactured by Broadcom Limited, confirming product family continuity.

Status Transition: The substitute part transitions from obsolete to active product status, ensuring long-term supply chain availability and continued manufacturing support.

Compliance Alignment: Both parts maintain ROHS3 compliance and are classified within the same product category. The substitute retains the same color specification (white, neutral 4500K) and package format (2835 metric).

Moisture Sensitivity Consideration: The substitute part carries MSL 3 (168 Hours) compared to the main part's MSL 1 (Unlimited). This indicates stricter moisture handling requirements during storage and assembly operations. MSL 3 classification requires baking procedures prior to reflow soldering if the component has been exposed to ambient humidity for extended periods.

Packaging Format: The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume surface-mount assembly operations and differs from the main part's unspecified packaging format.

Frequently Asked Questions (FAQ)

Q: Can CSMW-LWG0-NS0EE be used as a direct replacement for CSMW-LWG0-NSTEE?

A: Yes. Both parts are from the same Broadcom Limited product family (base number CSMW-L), share identical color and CCT specifications (white, neutral 4500K), and use the same 2835 metric package. The substitute is the manufacturer-recommended equivalent.

Q: What is the significance of the product status change from Obsolete to Active?

A: The obsolete status of CSMW-LWG0-NSTEE indicates that Broadcom Limited has discontinued manufacturing and support for this part number. The active status of CSMW-LWG0-NS0EE ensures continued availability, manufacturing support, and compliance with current industry standards.

Q: How does the MSL 3 rating of the substitute affect handling procedures?

A: MSL 3 (168 Hours) requires that the component be baked at specified temperature and humidity conditions before reflow soldering if it has been stored in ambient conditions for more than 168 hours. MSL 1 (Unlimited) components have no such time restriction. Assembly procedures must account for this additional moisture management step.

Q: Are the electrical specifications identical between the two parts?

A: The main part specifies forward voltage (3.22V), test current (150mA), maximum current (240mA), luminous flux (59lm at 25°C), and efficiency (122 lm/W). The substitute part number is listed as the manufacturer-recommended equivalent, confirming electrical compatibility. Detailed electrical specifications for the substitute should be verified against the manufacturer's current datasheet.

Q: What is the difference in packaging format?

A: The substitute is supplied in Tape & Reel (TR) format, which is standard for automated surface-mount assembly. This format differs from the main part's unspecified packaging but is compatible with standard pick-and-place equipment used in manufacturing environments.

Q: Are both parts suitable for automotive applications?

A: The main part carries automotive grade classification with AEC-Q101 qualification. The substitute part's automotive suitability should be confirmed against the manufacturer's current datasheet, as this specification was not provided in the available data.
