Key Parameters

Substitute Part Grouping Explanation

Substitution of the PAM2400ACA330 is determined by the following critical parameters:

• Output Voltage: Must be fixed at 3.3V
• Output Current Capability: Minimum 400mA switch current
• Topology: Boost (step-up) configuration
• Package: TO-243AA physical form factor
• Switching Frequency: 100kHz operation
• Input Voltage Range: Must accommodate 0.9V minimum input
• Regulatory Compliance: ROHS3 compliance required

The XC6372A331PR-G from Torex Semiconductor Ltd meets these core substitution criteria while maintaining functional and electrical compatibility within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

The XC6372A331PR-G is the qualified substitute for the obsolete PAM2400ACA330. Both components share identical output voltage (3.3V fixed), output current capability (400mA), switching frequency (100kHz), and package form factor (TO-243AA). The substitute maintains ROHS3 compliance and operates within compatible input voltage and temperature ranges for standard applications.

The XC6372A331PR-G offers the advantage of active product status with current manufacturing availability, ensuring long-term supply chain reliability. The extended maximum input voltage rating (10V versus 5.5V) provides additional design margin for applications with variable input sources.

Frequently Asked Questions (FAQ)

Q: Can the XC6372A331PR-G directly replace the PAM2400ACA330 in existing designs?

A: Yes. Both components are boost regulators with identical 3.3V fixed output, 400mA output current, 100kHz switching frequency, and TO-243AA packaging. Pin-to-pin compatibility and functional equivalence are confirmed across the specified parameter set.

Q: What is the impact of the synchronous rectifier difference?

A: The PAM2400ACA330 includes integrated synchronous rectification, while the XC6372A331PR-G uses standard rectification. This affects efficiency characteristics but does not prevent functional substitution in applications where the 400mA output current and 3.3V regulation are the primary requirements.

Q: Are there temperature range considerations for substitution?

A: The XC6372A331PR-G operates from -30°C to 80°C, compared to the PAM2400ACA330 range of -40°C to 85°C. Applications requiring operation below -30°C or above 80°C require design review to confirm compatibility.

Q: Does the extended input voltage range of the XC6372A331PR-G affect substitution?

A: No. The XC6372A331PR-G accepts input voltages from 0.9V to 10V, which encompasses the PAM2400ACA330 range of 0.9V to 5.5V. This provides additional design flexibility without compromising compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the PAM2400ACA330 and XC6372A331PR-G are ROHS3 compliant and meet equivalent regulatory requirements for electronic component manufacturing and use.
