PAM2316AGCADJ Equivalent & Substitute Parts

Part Overview

The PAM2316AGCADJ is a buck switching regulator IC manufactured by Diodes Incorporated, designed for positive adjustable output applications with 2A output current capability. This device operates across an input voltage range of 2.7V to 5.5V and provides adjustable output voltage from 1V to 3.3V. The PAM2316AGCADJ is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PAM2316AGCADJ is determined by the following critical parameters:

• Topology & Function: Buck switching regulator with step-down capability
• Output Configuration: Positive adjustable output
• Output Current Rating: 2A minimum
• Package Compatibility: 8-WFDFN Exposed Pad surface mount
• Operating Temperature Range: -40°C to 85°C
• Synchronous Rectifier: Required
• Compliance Standards: ROHS3 compliant, REACH unaffected

The NCP6324BMTAATBG qualifies as a substitute based on matching topology, output configuration, current rating, package type, temperature range, and regulatory compliance. Differences in input voltage range and output voltage adjustment range do not preclude substitution when the application requirements fall within the substitute's specifications.

Parameter Comparison

Engineering Selection Recommendations

The NCP6324BMTAATBG is suitable as a substitute for the PAM2316AGCADJ based on the following factors:

• Product Status: The NCP6324BMTAATBG maintains active product status with onsemi, ensuring continued availability and manufacturing support, whereas the PAM2316AGCADJ is obsolete.
• Regulatory Compliance: Both devices maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.
• Electrical Compatibility: The substitute device matches critical electrical parameters including output current (2A), operating temperature range (-40°C to 85°C), and package configuration (8-WFDFN Exposed Pad).
• Functional Equivalence: Both devices implement buck topology with positive adjustable output and synchronous rectification, maintaining functional equivalence for step-down regulation applications.
• Voltage Range Considerations: The NCP6324BMTAATBG provides wider output voltage adjustment range (0.6V to 5.5V) compared to the original device (1V to 3.3V). Applications requiring output voltages within the PAM2316AGCADJ specification range will operate within the substitute's validated operating region.

Frequently Asked Questions (FAQ)

Q: Can the NCP6324BMTAATBG directly replace the PAM2316AGCADJ without circuit modifications?

A: The NCP6324BMTAATBG shares identical package type (8-WFDFN Exposed Pad), pinout compatibility, and functional topology with the PAM2316AGCADJ. Direct PCB replacement is feasible. However, external component values (feedback resistors for output voltage adjustment) may require recalculation based on the substitute device's feedback network specifications to achieve the desired output voltage.

Q: What are the key differences between these two devices?

A: The primary differences are manufacturer (Diodes Incorporated versus onsemi), product status (obsolete versus active), switching frequency (2.5MHz versus 3MHz), and output voltage adjustment range (1V-3.3V versus 0.6V-5.5V). The NCP6324BMTAATBG also accepts lower minimum input voltage (2.5V versus 2.7V).

Q: Is the NCP6324BMTAATBG available in the same packaging as the PAM2316AGCADJ?

A: Yes. Both devices use 8-WFDFN Exposed Pad surface mount packaging with identical footprint dimensions (2x2mm). PCB layout compatibility is maintained.

Q: Does the higher switching frequency of the NCP6324BMTAATBG affect circuit design?

A: The 3MHz switching frequency of the NCP6324BMTAATBG compared to 2.5MHz of the PAM2316AGCADJ may result in reduced output filter component sizes and improved transient response. Existing filter designs for the original device will function with the substitute, though optimization for the higher frequency may improve performance characteristics.

Q: Are there any compliance or certification differences?

A: Both devices maintain identical RoHS3 compliance and REACH unaffected status. MSL ratings are equivalent (Level 1, Unlimited). No compliance barriers exist for substitution.
