Substitute Part Grouping Explanation

The substitute part VCEW1151CDS-3BZH3-TR is identified as a functional equivalent based on the following substitution criteria:

Functional Category Match: Both components serve as LED indication discrete devices within the same product family from Stanley Electric Co.

Compliance Alignment: The substitute part maintains REACH Unaffected status, consistent with the original component. The substitute achieves ROHS3 compliance, providing enhanced environmental regulatory coverage.

Packaging Configuration: The substitute is supplied in Tape & Reel (TR) format, enabling automated assembly processes suitable for production environments.

Operational Parameters: The substitute operates at 3.1V forward voltage with a 20mA test current, establishing defined electrical operating conditions for indication applications.

Physical Form Factor: The substitute utilizes 0603 (1608 Metric) package dimensions (1.60mm L x 0.80mm W x 0.80mm H maximum), providing a standardized surface mount footprint.

Active Production Status: The substitute part is in active production with substantial inventory availability (116,156 pieces), ensuring long-term supply continuity.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Component Replacement: The SW1141CX-TR is obsolete and no longer manufactured. The VCEW1151CDS-3BZH3-TR provides functional equivalence as an active production alternative from the same manufacturer.

Compliance Considerations: Both components maintain REACH Unaffected status. The substitute part achieves ROHS3 compliance, which may be required for applications subject to current environmental regulations.

Supply Chain Continuity: The substitute part maintains active production status with significantly higher inventory availability, ensuring reliable long-term sourcing for production and support applications.

Moisture Handling: The substitute part carries MSL 2A (4 Weeks) classification, requiring standard moisture control procedures during storage and handling. This represents a change from the original part's MSL 1 rating and must be considered in manufacturing and storage protocols.

Physical Integration: Verification of mechanical compatibility with existing PCB layouts and assembly equipment is required, as the substitute specifies 0603 (1608 Metric) package dimensions.

Frequently Asked Questions (FAQ)

Q: Why is the SW1141CX-TR classified as obsolete?

A: The SW1141CX-TR has reached end-of-life status and is no longer manufactured by Stanley Electric Co. Existing inventory remains available as new original stock, but no future production is planned.

Q: Can the VCEW1151CDS-3BZH3-TR directly replace the SW1141CX-TR?

A: The VCEW1151CDS-3BZH3-TR is identified as a functional equivalent LED indication discrete component from the same manufacturer. Mechanical compatibility with existing designs must be verified based on package dimensions and PCB layout requirements.

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

A: The original part carries MSL 1 (Unlimited), while the substitute carries MSL 2A (4 Weeks). MSL 2A requires that the component be used within 4 weeks of the bag opening date under controlled humidity conditions. Standard moisture control procedures must be implemented during storage and handling.

Q: Is the substitute part RoHS compliant?

A: Yes, the VCEW1151CDS-3BZH3-TR is ROHS3 compliant. The original part's RoHS status is not specified in available documentation.

Q: What is the package format of the substitute part?

A: The VCEW1151CDS-3BZH3-TR is supplied in Tape & Reel (TR) format with 0603 (1608 Metric) package dimensions: 1.60mm length x 0.80mm width x 0.80mm maximum height.

Q: Are both parts from the same manufacturer?

A: Yes, both the SW1141CX-TR and VCEW1151CDS-3BZH3-TR are manufactured by Stanley Electric Co.

Q: What are the electrical operating parameters of the substitute?

A: The VCEW1151CDS-3BZH3-TR operates at 3.1V forward voltage (typical) with a 20mA test current. These parameters define the standard operating conditions for this LED indication component.
