AP2151AMP-13 Equivalent & Substitute Parts

Part Overview

The AP2151AMP-13 is a Power Management Integrated Circuit (PMIC) manufactured by Diodes Incorporated, functioning as a USB Power Switch with P-Channel output configuration. This device operates as a 1:1 power switch/driver rated for 500mA maximum output current in an 8-MSOP-EP surface mount package. The part is currently in Active product status with 3700 units available in inventory.

Equivalent and substitute parts are identified based on matching electrical specifications, mechanical compatibility, and functional equivalence within the USB power switching category. Substitute parts maintain identical or compatible performance parameters while offering alternative packaging options or minor specification variations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP2151AMP-13 are identified based on the following critical parameters that determine functional equivalence:

• Switch Type: USB Switch
• Output Type: P-Channel, High Side configuration
• Number of Outputs: 1
• Ratio - Input:Output: 1:1
• Voltage - Load: 2.7V ~ 5.5V
• Current - Output (Max): 500mA
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) Exposed Pad
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Substitute parts maintain these core electrical and mechanical specifications. Variations in Rds On (on-resistance) within the range of 90mOhm to 95mOhm are acceptable as they fall within typical device performance tolerances for this product category. Packaging designation (Tape & Reel vs. alternative formats) does not affect electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain electrical and mechanical compatibility with the AP2151AMP-13 across critical performance parameters. Selection among equivalent parts should be based on the following factors:

AP2145MPG-13: Active product status with MSL 1 rating. Rds On specification of 90mOhm provides lower on-resistance compared to the primary part, resulting in reduced power dissipation. Suitable for applications where thermal performance is a design consideration.

AP2151MPG-13: Active product status with MSL 1 rating. Identical Rds On specification (95mOhm) to the AP2151AMP-13, providing direct functional equivalence. Packaging designation differs (MPG vs. AMP) but electrical performance remains equivalent.

AP2155MPG-13: Obsolete product status with MSL 3 rating. While electrically equivalent with 90mOhm Rds On specification, the obsolete status and higher moisture sensitivity level (168-hour limit vs. unlimited) indicate this part is not recommended for new designs. Existing inventory availability does not offset the compliance and long-term supply risks associated with obsolete product classification.

For new designs and ongoing production, AP2151MPG-13 or AP2145MPG-13 are preferred selections due to Active product status and MSL 1 moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can AP2145MPG-13 be used as a direct replacement for AP2151AMP-13?

A: Yes. Both parts maintain identical electrical specifications for switch type, output configuration, voltage rating, and current capacity. The 5mOhm difference in Rds On (90mOhm vs. 95mOhm) is within acceptable tolerance for USB power switching applications. Both are Active products with MSL 1 rating.

Q: What is the significance of the packaging designation difference between AMP and MPG?

A: The packaging designation indicates the supplier device package format. Both AMP-13 and MPG-13 variants use the same 8-MSOP-EP physical package (8-TSSOP, 8-MSOP with 0.118" width and exposed pad). The electrical performance and pin configuration are identical.

Q: Why is AP2155MPG-13 listed as a substitute if it is obsolete?

A: AP2155MPG-13 is included in the parametric equivalents list due to matching electrical specifications. However, its Obsolete product status and MSL 3 moisture sensitivity rating make it unsuitable for new designs. Existing inventory should be reserved for legacy product support only.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 Compliant status, ensuring compatibility with environmental and regulatory requirements.

Q: What is the difference between MSL 1 and MSL 3 ratings?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and can be stored indefinitely without special handling. MSL 3 (168 Hours) requires the component to be used within 168 hours of package opening or stored in controlled humidity conditions. This affects supply chain logistics and shelf-life management.
