Equivalent & Substitute Parts for PT5503C
Part Overview
PT5503C, manufactured by Texas Instruments, is a Non-Isolated PoL Module DC DC Converter featuring a single output of 2V at a maximum current of 3A, with an input voltage requirement of 3.1V to 5.5V. This module was designed for Information Technology Equipment (ITE) in commercial applications and is currently listed as obsolete. As the PT5503C is no longer in active production, selecting approved substitute parts is necessary to maintain product lifecycle and ensure continued support for designs initially based on PT5503C.

Key Parameters
| Manufacturer Part Number | Manufacturer | Type | Number of Outputs | Voltage - Input (Min) | Voltage - Input (Max) | Voltage - Output 1 | Current - Output (Max) | Applications | Operating Temperature | Efficiency | Mounting Type | Package / Case | RoHS Status | MSL | REACH Status | Product Status |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| PT5503C | Texas Instruments | Non-Isolated PoL Module | 1 | 3.1V | 5.5V | 2V | 3A | ITE (Commercial) | -40°C ~ 85°C | 85% | Surface Mount | 5-SMD Module | ROHS3 Compliant | 1 (Unlimited) | REACH Unaffected | Obsolete |
Substitute Part Grouping Explanation
Substitute parts for PT5503C are grouped strictly by evaluating their compliance with the following electrical and mechanical parameters: Type (Non-Isolated PoL Module), Number of Outputs (1), Output Voltage range, Output Current capability, Input Voltage Range, Mounting Type (Surface Mount), Operating Temperature, Application (ITE Commercial), RoHS compliance, REACH status, and moisture sensitivity level (MSL). Substitute status is further validated by manufacturer listing under recommended alternatives. Obsolete status is considered to ensure only active and available replacements are matched.

Engineering Selection Recommendations
PT5503C is obsolete with the status marked as "Obsolete." Both TPS84320RUQT and TPS84410RKGR are active and are listed as manufacturer-recommended substitutes. All substitute parts are ROHS3 compliant and unaffected by REACH, supporting selection for new designs or product maintenance under environmental compliance. Moisture Sensitivity Level (MSL) for substitutes is specified, and surface-mounting requirements are met.
Frequently Asked Questions (FAQ)
Q: What are the key criteria for selecting a substitute for PT5503C?
A: Substitution requires matching type (Non-Isolated PoL Module), number of outputs, output voltage and current requirements, input voltage range, mounting type, operating temperature range, application, and compliance certifications.
Q: Are substitute modules available for immediate use in commercial applications?
A: Substitute parts TPS84320RUQT and TPS84410RKGR are listed as active by the manufacturer and support use in ITE (Commercial) environments.
Q: What mounting considerations are relevant when replacing PT5503C?
A: All listed substitutes are surface mount compatible. Check package/case specifics for alignment with existing board layouts.
Q: Does environmental compliance differ among PT5503C and its substitutes?
A: All listed parts, including the substitutes, have ROHS3 compliance and REACH unaffected status.
Q: How do substitution options handle moisture sensitivity?
A: The PT5503C has an MSL of 1 (Unlimited); substitutes (TPS84320RUQT, TPS84410RKGR) have an MSL of 3 (168 Hours). Consider this difference for production and handling environments.
