MIC58P01YN Equivalent & Substitute Parts

Part Overview

The MIC58P01YN is a Power Switch/Driver IC manufactured by Microchip Technology, designed for bipolar 1:1 switching applications with 500mA output capability in a 22-PDIP through-hole package. This component functions as a latched driver with 8 outputs, low-side output configuration, and integrated fault protection including over-temperature and UVLO monitoring. The MIC58P01YN is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitute parts for the MIC58P01YN are identified based on strict electrical and mechanical compatibility criteria. The primary substitute, MIC58P01YWM, maintains functional equivalence through identical core parameters: same manufacturer (Microchip Technology), same base product number (MIC58P01), identical switch type (latched driver), matching output configuration (8 outputs, 1:1 ratio, low-side, bipolar), equivalent electrical ratings (15V max load voltage, 500mA max output current), and identical fault protection features (over-temperature and UVLO).

The key substitution parameters are:

• Base product number: MIC58P01
• Switch type: Latched Driver
• Number of outputs: 8
• Input:Output ratio: 1:1
• Output configuration: Low Side, Bipolar
• Interface: Strobe, Parallel
• Maximum load voltage: 15V
• Maximum output current: 500mA
• Fault protection: Over Temperature, UVLO
• Operating temperature range: -55°C ~ 125°C

The primary difference between the main part and substitute is the packaging format: the MIC58P01YN uses through-hole 22-PDIP mounting, while the MIC58P01YWM uses surface-mount 24-SOIC packaging. This packaging difference requires PCB layout modification but does not affect electrical functionality or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MIC58P01YWM is the manufacturer-recommended substitute for the obsolete MIC58P01YN. Both parts maintain identical electrical specifications and fault protection capabilities, ensuring functional compatibility in power management applications requiring bipolar latched driver functionality.

Selection between these parts depends on PCB implementation requirements. The MIC58P01YN (through-hole, 22-PDIP) is suitable for legacy systems or applications requiring through-hole assembly. The MIC58P01YWM (surface-mount, 24-SOIC) is the active product offering and is recommended for new designs, providing space efficiency and modern manufacturing compatibility.

Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The MIC58P01YWM carries MSL 2 (1 Year) moisture sensitivity, requiring standard moisture control during storage and handling, compared to the MIC58P01YN's MSL 1 (Unlimited) rating.

Frequently Asked Questions (FAQ)

Q: Can the MIC58P01YWM directly replace the MIC58P01YN without circuit modification?

A: Electrical functionality is fully compatible. However, PCB layout modification is required due to packaging differences: the MIC58P01YN uses 22-PDIP through-hole mounting while the MIC58P01YWM uses 24-SOIC surface-mount packaging. Pin-to-pin electrical functionality remains identical.

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

A: Substitution compatibility is determined by: latched driver switch type, 8 output configuration, 1:1 input:output ratio, low-side bipolar output, strobe/parallel interface, 15V maximum load voltage, 500mA maximum output current, and identical over-temperature and UVLO fault protection.

Q: Why is the MIC58P01YN classified as obsolete?

A: The MIC58P01YN is obsolete due to packaging format discontinuation. The MIC58P01YWM represents the active product line continuation with identical electrical specifications in modern surface-mount packaging.

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

A: No. Both the MIC58P01YN and MIC58P01YWM operate across the identical temperature range of -55°C to 125°C (TA).

Q: What is the significance of the MSL rating difference?

A: The MIC58P01YN carries MSL 1 (Unlimited) moisture sensitivity, while the MIC58P01YWM carries MSL 2 (1 Year). This indicates the MIC58P01YWM requires standard moisture control during storage and handling within a one-year period, whereas the MIC58P01YN has no moisture sensitivity limitations.

Q: Are both parts RoHS compliant?

A: Yes. Both the MIC58P01YN and MIC58P01YWM are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.
