Engineering Selection Recommendations

Product Status Consideration: The STW1147ASE-TR is classified as obsolete. The VSTW1152GDSE-3D3L3-TR carries an active product status, indicating ongoing manufacturer support and availability.

Regulatory Compliance: Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The substitute part carries ROHS3 Compliant certification, which supersedes the RoHS Compliant status of the main part, indicating enhanced environmental compliance alignment with current regulatory requirements.

Tariff Classification: Both parts share identical HTSUS classification (8541.41.0000), confirming alignment within the same product category for trade and procurement purposes.

Supply Chain Availability: The substitute part (VSTW1152GDSE-3D3L3-TR) is listed as active with 1088 pieces in new original stock, compared to the obsolete status of the main part with 781 pieces available. Active status ensures continued availability and manufacturer support for future procurement cycles.

Frequently Asked Questions (FAQ)

Q: Can the VSTW1152GDSE-3D3L3-TR directly replace the STW1147ASE-TR in existing designs?

A: Direct replacement requires verification of electrical parameters (forward voltage, test current, brightness output) and mechanical fit (package dimensions, mounting footprint, height clearance). The input data provided does not include complete electrical specifications for the substitute part. Consult detailed datasheets for both components to confirm compatibility with your specific application requirements.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Obsolete status indicates the STW1147ASE-TR is no longer in active production. The substitute part's active status ensures ongoing manufacturer support, continued availability, and compliance with current regulatory standards. For long-term supply chain planning, active parts are preferred.

Q: Are there packaging or handling differences between these parts?

A: Both parts are surface mount components. The main part specifies 2-SMD, No Lead packaging with MSL 4 (72 Hours) moisture sensitivity. The substitute part's complete packaging specifications are not provided in the input data. Verify moisture sensitivity levels and storage requirements before implementation.

Q: How do the RoHS compliance levels differ?

A: The main part is RoHS Compliant (RoHS 2). The substitute part is ROHS3 Compliant, representing a more recent regulatory standard. ROHS3 compliance is backward compatible with RoHS 2 requirements and indicates alignment with current environmental directives.

Q: What parameters must match for successful substitution?

A: Critical matching parameters include forward voltage (3.2V), test current (20mA), brightness output (2000mcd), surface mount configuration, and physical dimensions (2.40mm × 1.85mm footprint, 0.70mm maximum height). Optical characteristics (white color, diffused lens, 120° viewing angle) must also be verified against application requirements.
