TPS2223PWP Equivalent & Substitute Parts

Part Overview

The TPS2223PWP is a Power Switch/Driver IC designed for PCMCIA switch applications, featuring a 3:4 input-to-output ratio with 1A maximum output current per channel. This component operates across 3.3V and 5V load voltage levels and includes integrated current limiting and over-temperature fault protection. The TPS2223PWP is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS2223PWP are identified based on strict electrical and mechanical parameter matching within the TPS2223 product family. The substitution logic is based on the following critical parameters:

• Switch Type: PCMCIA Switch
• Number of Outputs: 4
• Ratio - Input:Output: 3:4
• Output Configuration: High Side
• Interface: Serial
• Voltage - Load: 3.3V, 5V
• Current - Output (Max): 1A
• Rds On (Typ): 95mOhm
• Fault Protection: Current Limiting (Fixed), Over Temperature
• Operating Temperature: -40°C ~ 85°C (TA)

Two substitute parts meet these electrical specifications while differing in packaging and product status:

1. TPS2223APWP - Parametric equivalent with identical electrical specifications and package type (24-HTSSOP), but with active product status and improved moisture sensitivity rating.
2. TPS2223DB - Manufacturer-recommended substitute with identical electrical specifications but different package type (24-SSOP) and active product status.

Parameter Comparison

Engineering Selection Recommendations

TPS2223APWP is the preferred substitute when PCB layout and component placement accommodate the 24-HTSSOP package footprint. This part maintains identical package dimensions and electrical specifications to the TPS2223PWP while offering active product status and long-term availability. The TPS2223APWP carries the same MSL rating (2, 1 Year) as the original part.

TPS2223DB is the manufacturer-recommended alternative when package footprint flexibility exists in the design. This part features a larger 24-SSOP package (0.209", 5.30mm Width) compared to the 24-HTSSOP (0.173", 4.40mm Width), but provides superior moisture sensitivity characteristics (MSL 1, Unlimited) and active product status. PCB redesign is required to accommodate the different package dimensions.

Both substitute parts maintain full electrical equivalence with the TPS2223PWP, including identical output current ratings, on-resistance, fault protection mechanisms, and operating temperature ranges. Both are ROHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can TPS2223APWP be used as a direct replacement for TPS2223PWP without PCB modifications?

A: Yes. The TPS2223APWP uses the identical 24-HTSSOP package footprint (0.173", 4.40mm Width) as the TPS2223PWP, enabling direct PCB substitution without layout changes.

Q: What are the key differences between TPS2223APWP and TPS2223DB?

A: The primary difference is package type. TPS2223APWP uses 24-HTSSOP (0.173" width), while TPS2223DB uses 24-SSOP (0.209" width). Both maintain identical electrical specifications. TPS2223DB offers improved moisture sensitivity (MSL 1 vs. MSL 2).

Q: Are all three parts electrically interchangeable?

A: Yes, all three parts (TPS2223PWP, TPS2223APWP, TPS2223DB) are electrically interchangeable. They share identical switch type, output configuration, current ratings, on-resistance, fault protection, and operating temperature specifications.

Q: Why is the TPS2223PWP classified as obsolete?

A: Product obsolescence is determined by the manufacturer. Active alternatives (TPS2223APWP and TPS2223DB) are available from Texas Instruments for new designs and ongoing production requirements.

Q: Does package selection affect electrical performance?

A: No. The 24-HTSSOP and 24-SSOP packages contain identical die and electrical characteristics. Package selection is determined by PCB layout constraints and available board space.

Q: Are there compliance differences between the substitute parts?

A: All three parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity differs: TPS2223PWP and TPS2223APWP are MSL 2 (1 Year), while TPS2223DB is MSL 1 (Unlimited).
