PAM2400ACA500 Equivalent & Substitute Parts

Part Overview

The PAM2400ACA500 is a boost switching regulator IC manufactured by Diodes Incorporated, designed to provide a fixed 5V output with 400mA switch current capability. This component operates as a step-up converter with a single positive output, suitable for applications requiring voltage elevation from low input sources. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. The XC6372A501PR-G from Torex Semiconductor Ltd serves as the manufacturer-recommended substitute, offering comparable electrical performance within the same physical package footprint.

Substitute Part Grouping Explanation

Substitution of the PAM2400ACA500 with the XC6372A501PR-G is based on alignment of the following critical electrical and mechanical parameters:

• Output Voltage: Both devices deliver fixed 5V output
• Output Current: Both support 400mA switch current
• Switching Frequency: Both operate at 100kHz
• Package / Case: Both use TO-243AA physical package
• Mounting Type: Both are surface mount components
• Topology: Both implement boost (step-up) switching regulator topology
• Output Configuration: Both provide positive fixed output
• Compliance: Both meet ROHS3 and REACH requirements

The XC6372A501PR-G is qualified as a direct substitute based on these matching parameters, enabling seamless integration into existing PCB designs without layout modifications.

Parameter Comparison

Engineering Selection Recommendations

The XC6372A501PR-G is the manufacturer-recommended substitute for the obsolete PAM2400ACA500. Selection of this alternative is supported by the following factors:

Product Status: The PAM2400ACA500 is obsolete, while the XC6372A501PR-G maintains active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: Both components meet ROHS3 and REACH requirements, maintaining compliance with current environmental and hazardous substance regulations.

Electrical Equivalence: Core electrical parameters—output voltage (5V), output current (400mA), switching frequency (100kHz), and input voltage minimum (0.9V)—are identical between both devices.

Physical Compatibility: Both components use the TO-243AA package in surface mount configuration, enabling direct PCB substitution without layout redesign.

Input Voltage Range: The XC6372A501PR-G accepts a maximum input voltage of 10V compared to 5.5V for the PAM2400ACA500, providing enhanced flexibility for applications with variable input sources.

Operating Temperature Consideration: The PAM2400ACA500 operates across -40°C to 85°C, while the XC6372A501PR-G operates across -30°C to 80°C. Applications requiring operation below -30°C or above 80°C must evaluate this parameter difference against specific system requirements.

Synchronous Rectifier Difference: The PAM2400ACA500 includes an integrated synchronous rectifier, while the XC6372A501PR-G does not. This architectural difference may affect efficiency characteristics in specific load conditions but does not prevent functional substitution for standard boost regulator applications.

Frequently Asked Questions (FAQ)

Q: Can the XC6372A501PR-G directly replace the PAM2400ACA500 on existing PCBs?

A: Yes. Both components share identical TO-243AA package dimensions and surface mount configuration. No PCB layout modifications are required for physical substitution.

Q: What are the key electrical parameters that define substitution compatibility?

A: The critical parameters are fixed 5V output voltage, 400mA switch current, 100kHz switching frequency, 0.9V minimum input voltage, and single positive output configuration. Both devices match these specifications.

Q: Why is the PAM2400ACA500 classified as obsolete?

A: The PAM2400ACA500 has reached end-of-life status with Diodes Incorporated. The XC6372A501PR-G is the active production alternative recommended for new designs and ongoing support.

Q: Are there differences in operating temperature ranges between these parts?

A: Yes. The PAM2400ACA500 operates from -40°C to 85°C, while the XC6372A501PR-G operates from -30°C to 80°C. Applications requiring operation below -30°C or above 80°C must account for this difference.

Q: What is the difference between synchronous and non-synchronous rectifier implementations?

A: The PAM2400ACA500 includes an integrated synchronous rectifier for improved efficiency, while the XC6372A501PR-G uses a standard rectifier approach. Both topologies deliver the specified 5V output and 400mA current, with efficiency differences dependent on specific load conditions and input voltage levels.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the PAM2400ACA500 and XC6372A501PR-G are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the input voltage range for each component?

A: The PAM2400ACA500 accepts input voltage from 0.9V to 5.5V. The XC6372A501PR-G accepts input voltage from 0.9V to 10V, providing a wider input range suitable for applications with variable source voltages.

Q: What packaging options are available for the XC6372A501PR-G?

A: The XC6372A501PR-G is supplied in Tape & Reel (TR) packaging, standard for high-volume production environments.
