Parameter Comparison

Engineering Selection Recommendations

The CSMW-LWG0-NS0FE is the manufacturer-recommended substitute for the obsolete CSMW-LWG0-NSTFE. Both components share the same base product number (CSMW-L) and are manufactured by Broadcom Limited, confirming design lineage and compatibility.

Product Status Consideration: The main part is classified as obsolete, while the substitute maintains active product status. This transition ensures continued availability and manufacturing support for new production runs and field replacements.

Compliance Alignment: Both parts maintain ROHS3 compliance and automotive-grade classification. The substitute part carries the same base electrical and mechanical specifications required for automotive lighting applications.

Packaging Transition: The substitute part is supplied in Tape & Reel (TR) format, which is standard for high-volume surface-mount production. The original part packaging format was not specified in the input data.

Moisture Sensitivity: The substitute part carries MSL 3 (168 Hours) rating compared to the main part's MSL 1 (Unlimited). This represents a more restrictive moisture handling requirement during storage and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can CSMW-LWG0-NS0FE directly replace CSMW-LWG0-NSTFE in existing designs?

A: Yes. Both components share identical base product designation (CSMW-L), same color specification (White, Neutral 4000K), and equivalent package type (2835 metric). The substitute maintains automotive-grade classification and ROHS3 compliance required for the original application.

Q: What is the primary reason for substitution?

A: The CSMW-LWG0-NSTFE is classified as obsolete. The CSMW-LWG0-NS0FE is the active equivalent from the same manufacturer, ensuring continued component availability and manufacturing support.

Q: Are there differences in electrical performance between these parts?

A: The input data does not provide complete electrical specifications for the substitute part. Detailed electrical parameters (forward voltage, test current, luminous flux, efficiency) are specified only for the main part. Confirmation of electrical equivalence requires review of the substitute part's complete datasheet.

Q: What is the difference in moisture sensitivity levels?

A: The main part carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The substitute carries MSL 3 (168 Hours), requiring controlled storage conditions and limiting the time the component can be exposed to ambient humidity before assembly. This requires adjustment to component handling procedures during manufacturing.

Q: Is the package format change significant?

A: The substitute is supplied in Tape & Reel (TR) format, which is standard for automated surface-mount assembly. The original part's packaging format was not specified in the input data. Tape & Reel format is compatible with standard pick-and-place equipment used in production environments.

Q: Are both parts qualified for automotive applications?

A: Yes. Both components are classified as automotive-grade and carry AEC-Q101 qualification, meeting automotive industry reliability and performance standards.

Q: What parameters must be verified for substitution compatibility?

A: Critical parameters for substitution include: color (White, Neutral 4000K), package type (2835 metric), forward voltage (3.22V nominal), test current (150mA), maximum current (240mA), luminous flux (59lm at 25°C), and automotive qualification (AEC-Q101). The substitute part must meet or exceed these specifications.
