TPS2223DBR Equivalent & Substitute Parts

Part Overview

The TPS2223DBR is a Power Management Integrated Circuit (PMIC) functioning as a power switch/driver with a 3:4 input-to-output ratio and 1A maximum output current. Designed for PCMCIA switch applications, this component provides high-side output configuration with serial interface control and integrated fault protection including current limiting and over-temperature monitoring.

The TPS2223DBR carries an Obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2223DBR is determined by strict equivalence across 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
• Features: Status Flag
• Fault Protection: Current Limiting (Fixed), Over Temperature
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 24-SSOP (0.209", 5.30mm Width)

The TPS2223ADBR meets all these criteria and qualifies as a parametric equivalent substitute. The primary distinction between these parts is product status and packaging format, not electrical or mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The TPS2223ADBR is the direct substitute for the obsolete TPS2223DBR. Both components share identical electrical specifications, thermal characteristics, and mechanical packaging. The TPS2223ADBR maintains Active product status, ensuring ongoing manufacturer support and supply availability.

Both parts comply with ROHS3 and carry unaffected REACH status. MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either component.

Selection of the TPS2223ADBR over the TPS2223DBR is driven by product lifecycle considerations: the substitute part remains in active production and distribution, eliminating obsolescence risk while maintaining full functional and physical compatibility.

Frequently Asked Questions (FAQ)

Q: Are the TPS2223DBR and TPS2223ADBR electrically identical?

A: Yes. Both components share identical electrical specifications including output current rating (1A), on-resistance (95mOhm), voltage ratings (3.3V, 5V), fault protection mechanisms, and operating temperature range (-40°C to 85°C).

Q: What is the primary difference between these parts?

A: Product status and packaging format. The TPS2223DBR is Obsolete and supplied in bulk packaging. The TPS2223ADBR is Active and supplied in Tape & Reel (TR) format. Electrical and mechanical specifications are identical.

Q: Can the TPS2223ADBR be used as a direct replacement in existing designs?

A: Yes. The 24-SSOP package dimensions are identical, and all electrical parameters match. No circuit modifications or PCB redesign is required.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, unaffected REACH status, and identical MSL ratings. Regulatory and environmental certifications are equivalent.

Q: Why should I transition from TPS2223DBR to TPS2223ADBR?

A: The TPS2223DBR is obsolete and subject to supply discontinuation. The TPS2223ADBR ensures long-term availability and manufacturer support while providing identical functionality and performance.
