Key Parameters

Substitute Part Grouping Explanation

Substitution of the VCMW1154LCS-3CYA3-TR is determined by the following critical parameters:

Functional Category: LED indication lamp, discrete component type Package Format: PLCC surface mount configuration Moisture Sensitivity Level: MSL 3 (168 Hours) - determines storage and handling requirements Manufacturer Consistency: Stanley Electric Co maintains design compatibility across product series Environmental Compliance: REACH Unaffected status ensures regulatory alignment

The substitute part VCHW1154LA3SE-3C4A3-TR meets these criteria through identical MSL classification, matching PLCC package format, equivalent LED indication function, and active product status with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production: The VCHW1154LA3SE-3C4A3-TR is the appropriate selection. This part carries active product status with ongoing manufacturer support, ROHS3 compliance certification, and confirmed current inventory availability. The active status ensures long-term supply chain stability and access to technical documentation.

For Existing Stock Management: The VCMW1154LCS-3CYA3-TR remains available with substantial inventory (3400 units). This part is suitable for existing applications where design validation has been completed and supply is confirmed through current stock.

Compliance Considerations: Both parts maintain REACH Unaffected status and identical MSL 3 classification. The substitute part adds ROHS3 Compliant certification, providing enhanced environmental compliance documentation for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can VCHW1154LA3SE-3C4A3-TR directly replace VCMW1154LCS-3CYA3-TR in existing designs?

A: Yes. Both components share identical PLCC package format, MSL 3 moisture sensitivity classification, and LED indication discrete function. The substitute part is manufactured by the same supplier (Stanley Electric Co) and maintains functional equivalence for LED indication applications.

Q: What is the significance of the MSL 3 (168 Hours) rating for both parts?

A: MSL 3 indicates the component requires controlled moisture exposure during storage and handling. Both parts must be stored in dry conditions and have a floor life of 168 hours after moisture absorption begins. This specification is identical between the original and substitute part, ensuring equivalent handling requirements.

Q: Why is the original part classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for the VCMW1154LCS-3CYA3-TR. The VCHW1154LA3SE-3C4A3-TR represents the active product line continuation from Stanley Electric Co for this component category.

Q: Are there differences in ROHS compliance between the two parts?

A: The original part does not specify RoHS status in available documentation. The substitute part carries explicit ROHS3 Compliant certification, providing documented compliance for applications requiring RoHS verification.

Q: What is the difference between ECCN "OBSOLETE" and "EAR99"?

A: ECCN OBSOLETE indicates the original part is no longer subject to export control classification due to discontinuation. ECCN EAR99 for the substitute part indicates standard commercial classification under U.S. export regulations, applicable to active products.

Q: Should I transition existing designs to the substitute part?

A: Transition to the substitute part is appropriate for new production runs and long-term supply planning. Existing designs using current VCMW1154LCS-3CYA3-TR stock may continue until inventory depletion, after which the VCHW1154LA3SE-3C4A3-TR becomes the required selection.
