MIC94164YCS-TR Equivalent & Substitute Parts

Part Overview

The MIC94164YCS-TR is a Power Management Integrated Circuit (PMIC) manufactured by Microchip Technology, classified as a Power Switch/Driver with 1:1 P-Channel configuration. This component functions as a high-side power switch rated for 3A output current with integrated load discharge and slew rate control features. The part is currently in Active product status with 1900 units available in new original inventory.

Substitute parts become necessary when the primary component reaches end-of-life status, experiences supply constraints, or when design flexibility requires alternative sourcing options while maintaining functional equivalence within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC94164YCS-TR is determined by strict alignment of the following critical parameters:

• Output Configuration: High Side
• Output Type: P-Channel
• Number of Outputs: 1
• Ratio - Input:Output: 1:1
• Current - Output (Max): 3A minimum
• Voltage - Load: Range must encompass or match 1.7V ~ 5.5V
• Package / Case: 6-WFBGA or 6-WLCSP variants
• Mounting Type: Surface Mount
• Operating Temperature: -40°C ~ 125°C (TJ)

The NCP337FCT2G from onsemi meets these substitution criteria. Although classified as Obsolete in product status, it maintains functional equivalence across all specified electrical parameters and mechanical packaging requirements. The load voltage range of 1.2V ~ 5.5V encompasses the primary part's 1.7V ~ 5.5V specification, and the 3A output current rating matches the requirement.

Parameter Comparison

Engineering Selection Recommendations

The MIC94164YCS-TR maintains Active product status with current inventory availability. Selection of this primary part is appropriate for new designs and ongoing production where supply is not constrained.

The NCP337FCT2G is classified as Obsolete and should be considered only when the primary part becomes unavailable. Both components carry ROHS3 compliance and REACH Unaffected status, meeting equivalent regulatory requirements. The NCP337FCT2G provides functional substitution with the following considerations based on provided specifications: the load voltage range extends to 1.2V (lower than the primary part's 1.7V minimum), and the Rds On typical value is 20Ohm compared to 14.5mOhm for the primary part. Both components are rated for identical 3A output current and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can NCP337FCT2G be used as a direct replacement for MIC94164YCS-TR?

A: Yes, within the specified electrical and mechanical parameters. Both components share identical output configuration (High Side P-Channel 1:1), current rating (3A), operating temperature range (-40°C ~ 125°C), and surface mount 6-WLCSP packaging. The NCP337FCT2G is classified as Obsolete, making it suitable only when the primary part is unavailable.

Q: What are the key differences between these parts?

A: The primary differences are: (1) Rds On typical value is 14.5mOhm for MIC94164YCS-TR versus 20Ohm for NCP337FCT2G; (2) Load voltage range is 1.7V ~ 5.5V for MIC94164YCS-TR versus 1.2V ~ 5.5V for NCP337FCT2G; (3) Product status is Active for MIC94164YCS-TR versus Obsolete for NCP337FCT2G; (4) Supplier device package dimensions are 1x1.5 versus 1.0x1.5 respectively.

Q: Are there packaging compatibility concerns?

A: Both parts use 6-WLCSP (Wafer Level Chip Scale Package) with minor dimensional variations (1x1.5 versus 1.0x1.5). Both are surface mount components with identical MSL rating of 1 (Unlimited). PCB layout and reflow profiles should accommodate the specified package dimensions.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MIC94164YCS-TR and NCP337FCT2G are ROHS3 Compliant and REACH Unaffected, meeting equivalent regulatory requirements for electronic component use.

Q: What determines substitution eligibility for this product category?

A: Substitution is based on matching: output configuration (High Side), output type (P-Channel), number of outputs (1), input-output ratio (1:1), maximum output current (3A), load voltage range compatibility, package type (6-WLCSP), mounting type (Surface Mount), and operating temperature range (-40°C ~ 125°C).
