Engineering Selection Recommendations

VTEW1151ASE-50Y-TR (Parametric Equivalent):

This part is the primary substitute for the VTEW1151ASE-57Y-TR. It maintains identical electrical specifications (3.3V forward voltage, 150mA test current, 170mA maximum current), optical performance (37lm luminous flux, 75 lm/W efficiency, 85 CRI), mechanical configuration (1010 package, 145° viewing angle), and thermal characteristics (40°C/W). The only parameter difference is color temperature: 5000K versus 5700K. Both parts are classified as obsolete and carry equivalent RoHS and REACH compliance certifications. This substitute is suitable for applications where the 700K color temperature difference is acceptable within the cool white spectrum range.

VXLW1155GS-57Y-TR (Similar Alternative):

This part shares the same manufacturer (Stanley Electric Co) and matches the 5700K color temperature specification of the main part. However, detailed electrical and optical parameters are not provided in the available documentation. This part is classified as active product status, indicating current manufacturing availability. The VXLW1155GS-57Y-TR is designated as LED Indication rather than LED Lighting, suggesting a different functional application category. This part carries ROHS3 compliance, representing a more recent regulatory standard than the RoHS compliance of the main part. Selection of this alternative requires verification of undocumented electrical parameters against circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can VTEW1151ASE-50Y-TR be used as a direct replacement for VTEW1151ASE-57Y-TR?

A: VTEW1151ASE-50Y-TR is electrically and mechanically compatible with VTEW1151ASE-57Y-TR. All critical parameters—forward voltage, test current, maximum current, luminous flux, efficiency, CRI, viewing angle, package type, and thermal resistance—are identical. The color temperature differs by 700K (5000K versus 5700K), both within the cool white spectrum. Selection depends on whether the application tolerates this color temperature variation.

Q: What is the difference between the two obsolete parts?

A: VTEW1151ASE-57Y-TR and VTEW1151ASE-50Y-TR differ only in color temperature specification. The "57Y" designation indicates 5700K, while "50Y" indicates 5000K. All other electrical, optical, and mechanical parameters are identical. Both parts are obsolete, indicating discontinued manufacturing.

Q: Is VXLW1155GS-57Y-TR suitable for replacement?

A: VXLW1155GS-57Y-TR shares the 5700K color temperature and Stanley Electric Co manufacturer. However, this part is categorized as LED Indication rather than LED Lighting, and detailed electrical specifications are not provided. Direct substitution requires confirmation that undocumented parameters (forward voltage, test current, luminous flux) meet circuit requirements. The active product status indicates current availability.

Q: What compliance certifications apply to these parts?

A: VTEW1151ASE-57Y-TR and VTEW1151ASE-50Y-TR carry RoHS Compliant and REACH Unaffected certifications. VXLW1155GS-57Y-TR carries ROHS3 Compliant and REACH Unaffected certifications. ROHS3 represents a more recent regulatory iteration than RoHS Compliant. All parts are classified under ECCN EAR99 and HTSUS 8541.41.0000.

Q: Are the package dimensions identical across all three parts?

A: VTEW1151ASE-57Y-TR and VTEW1151ASE-50Y-TR both use the 1010 (2525 Metric) package with identical dimensions (0.098" L x 0.098" W / 2.50mm x 2.50mm) and maximum seated height (0.083" / 2.10mm). Package specifications for VXLW1155GS-57Y-TR are not provided in available documentation.

Q: What is the moisture sensitivity level for these parts?

A: VTEW1151ASE-57Y-TR and VTEW1151ASE-50Y-TR both carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. Moisture sensitivity level for VXLW1155GS-57Y-TR is not specified.

Q: How do the thermal characteristics compare?

A: VTEW1151ASE-57Y-TR and VTEW1151ASE-50Y-TR both have thermal resistance of 40°C/W. Thermal resistance for VXLW1155GS-57Y-TR is not provided.
