Engineering Selection Recommendations

The AP2145MPG-13 is the primary selection for new designs due to its Active product status and MSL Level 1 classification, which provides unlimited moisture sensitivity tolerance. This ensures superior reliability in storage and handling environments without moisture bake-out requirements.

The AP2155MPG-13 is a parametric equivalent with identical electrical and mechanical specifications. However, this part carries Obsolete product status and MSL Level 3 classification (168-hour moisture sensitivity limit). Selection of the AP2155MPG-13 is appropriate only when inventory constraints of the AP2145MPG-13 exist and when moisture control procedures are implemented during component storage and assembly operations.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting environmental regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can AP2155MPG-13 be used as a direct replacement for AP2145MPG-13?

A: Yes, the AP2155MPG-13 is a parametric equivalent with identical electrical performance, output configuration, current rating, and package specifications. Direct pin-for-pin substitution is supported at the circuit level.

Q: What is the significance of the Obsolete product status for AP2155MPG-13?

A: Obsolete status indicates the part is no longer manufactured. While existing inventory may be available, long-term supply cannot be guaranteed. The AP2145MPG-13 (Active status) is recommended for designs requiring sustained component availability.

Q: How does MSL Level 1 differ from MSL Level 3?

A: MSL Level 1 (AP2145MPG-13) has unlimited moisture sensitivity tolerance, requiring no special storage conditions. MSL Level 3 (AP2155MPG-13) requires moisture control with a 168-hour limit before component use, necessitating moisture bake-out procedures if storage time exceeds this threshold.

Q: Are the package dimensions identical between both parts?

A: Yes, both parts use 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) Exposed Pad packaging with Surface Mount mounting type. PCB layout and footprint compatibility is maintained.

Q: What fault protection mechanisms are present in both parts?

A: Both AP2145MPG-13 and AP2155MPG-13 include Current Limiting (Fixed), Over Temperature, Reverse Current, and UVLO (Under Voltage Lock Out) protection features.

Q: Is the 90mOhm Rds On specification identical for both parts?

A: Yes, both parts specify 90mOhm typical on-resistance, ensuring equivalent power dissipation and thermal performance in circuit applications.
