Parameter Comparison

Engineering Selection Recommendations

Both UCS2113T-1-V/G4 and UCS2113T-2-V/G4 are active, RoHS3 compliant, and REACH unaffected, ensuring they meet current regulatory requirements. The only distinction is in the Moisture Sensitivity Level (MSL): UCS2113T-1-V/G4 has MSL 3 (168 hours), while UCS2113T-2-V/G4 features MSL 1 (unlimited floor life). Select according to assembly process requirements regarding moisture sensitivity. All other electrical, thermal, and package features are identical based on supplied parameters.

Frequently Asked Questions (FAQ)

Q1: What determines whether UCS2113T-2-V/G4 can substitute for UCS2113T-1-V/G4?
A1: Substitution is based on identical switch type, electrical ratings, protection features, package, and regulatory (RoHS/REACH) compliance. Both parts conform to all key parameters required for equivalence.

Q2: Are there layout or assembly differences when using these power switch ICs?
A2: Both UCS2113T-1-V/G4 and UCS2113T-2-V/G4 share the 20-QFN (4x4) exposed pad package, ensuring compatibility with the same PCB land pattern.

Q3: Does Moisture Sensitivity Level (MSL) affect functional substitution?
A3: MSL differences do not affect core functionality but are relevant to assembly and storage procedures. UCS2113T-1-V/G4 is MSL 3 (168 hours), while UCS2113T-2-V/G4 is MSL 1 (unlimited).

Q4: Are both parts compliant with environmental and export regulations?
A4: Yes, both are ROHS3 Compliant and REACH Unaffected.

Q5: Can these substitute parts be sourced in different packaging options?
A5: Both are available in cut tape and tape & reel/surface mount configurations as specified by the supplier.
