MIC5397-GPYMX-TR Equivalent & Substitute Parts

Part Overview

The MIC5397-GPYMX-TR is a linear voltage regulator IC from Microchip Technology designed for power management applications. This dual-output positive fixed regulator delivers 300mA per channel and operates across a wide input voltage range up to 5.5V. The device is currently in active production status with 731 units available in inventory. Alternative components may be required due to design optimization, supply chain considerations, or specific application requirements where substitute parts meet or exceed the electrical and mechanical specifications of the original design.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC5397-GPYMX-TR must satisfy the following criteria based on allowed electrical and mechanical parameters:

Critical Matching Parameters:

• Dual-output positive fixed linear voltage regulator configuration
• Minimum 300mA output current per channel
• Maximum input voltage of 5.5V or greater
• Fixed output voltage options including 1.8V and/or 3V
• 8-pin DFN or XFDFN package with exposed pad
• Surface mount technology
• Active product status
• ROHS3 compliance

The NCP154MX330300TAG from onsemi qualifies as a substitute based on these parameters. While output voltage options differ (3V and 3.3V versus 1.8V and 3V), the device maintains dual-output configuration, 300mA per channel capability, compatible package geometry, and active production status. The substitute operates within acceptable input voltage and thermal ranges for equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MIC5397-GPYMX-TR and NCP154MX330300TAG maintain active production status and ROHS3 compliance, qualifying them for equivalent applications. Selection between these components should be based on specific output voltage requirements and operating temperature constraints. The MIC5397-GPYMX-TR supports 1.8V output and extends to 125°C maximum operating temperature. The NCP154MX330300TAG provides improved voltage dropout performance and higher PSRR but operates to 85°C maximum and does not include 1.8V output option. Both devices are surface-mount compatible with identical package footprints and deliver equivalent current capacity per output channel.

Frequently Asked Questions (FAQ)

Q: Can the NCP154MX330300TAG replace the MIC5397-GPYMX-TR in all applications?

A: Substitution is valid only when the application does not require 1.8V output and operates within the -40°C to 85°C temperature range. The NCP154MX330300TAG supports 3V and 3.3V outputs with identical 300mA per channel capacity and compatible 8-XFDFN package footprint.

Q: What are the key differences in electrical performance?

A: The NCP154MX330300TAG exhibits lower voltage dropout (0.26V versus 0.38V at 300mA) and higher PSRR (75dB versus 60dB at 1kHz). Quiescent current is higher in the substitute (100 µA versus 55 µA). Maximum input voltage is slightly lower (5.25V versus 5.5V).

Q: Are the packages mechanically compatible?

A: Both devices use 8-XFDFN packages with exposed pads and identical footprints (1.2x1.6mm and 1.6x1.2mm respectively). PCB layout and reflow profiles remain compatible between the two components.

Q: What compliance certifications apply to both parts?

A: Both the MIC5397-GPYMX-TR and NCP154MX330300TAG are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001.

Q: How do operating temperature ranges affect substitution decisions?

A: The MIC5397-GPYMX-TR operates to 125°C while the NCP154MX330300TAG operates to 85°C. Applications requiring operation above 85°C must use the original MIC5397-GPYMX-TR component.
