X4163PIZ Equivalent & Substitute Parts

Part Overview

The X4163PIZ is a supervisor integrated circuit manufactured by Renesas Electronics Corporation, designed for power management applications. It functions as a simple reset/power-on reset device with open drain or open collector output, monitoring a single voltage channel. The device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or component replacement in production environments. The X4163PIZ operates across the industrial temperature range of -40°C to 85°C and is housed in an 8-DIP package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X4163PIZ is determined by the following critical parameters:

• Functional Type: Simple reset/power-on reset supervisor with single voltage channel monitoring
• Output Configuration: Open drain or open collector output topology
• Reset Logic: Active low reset signal
• Package Format: 8-DIP through-hole mounting (0.300", 7.62mm)
• Voltage Threshold Range: Threshold values within acceptable tolerance of 4.38V
• Operating Temperature Range: Support for -40°C to 85°C industrial temperature range
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The MIC1232NY from Microchip Technology meets these substitution criteria. Both devices share identical functional classification, output type, reset polarity, package format, temperature range, and regulatory compliance status. Voltage threshold values (4.37V and 4.62V for MIC1232NY versus 4.38V for X4163PIZ) fall within acceptable engineering tolerance for supervisor applications.

Parameter Comparison

Engineering Selection Recommendations

The MIC1232NY is a direct functional equivalent to the X4163PIZ for power management supervisor applications. Both devices are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

The primary distinction between these parts is product lifecycle status: the X4163PIZ is obsolete, while the MIC1232NY maintains active production status. This difference is significant for long-term supply chain planning and component availability. The MIC1232NY is currently available in inventory (2280 pieces) compared to the X4163PIZ (679 pieces).

A secondary consideration is reset timeout specification: the MIC1232NY specifies 250ms minimum versus 100ms minimum for the X4163PIZ. This difference must be evaluated against specific application requirements for power-on reset timing.

Frequently Asked Questions (FAQ)

Q: Can the MIC1232NY directly replace the X4163PIZ in existing designs?

A: Yes, the MIC1232NY is functionally equivalent for supervisor applications. Both devices feature identical output topology (open drain/open collector), reset polarity (active low), package format (8-DIP), and operating temperature range (-40°C to 85°C). Voltage threshold values are within acceptable tolerance for supervisor circuits.

Q: What is the significance of the different reset timeout values?

A: The X4163PIZ specifies 100ms minimum reset timeout, while the MIC1232NY specifies 250ms minimum. Reset timeout defines the duration the reset output remains asserted after power supply stabilization. Applications with specific timing requirements must confirm that the 250ms specification of the MIC1232NY is compatible with system reset sequencing.

Q: Are both parts suitable for industrial temperature applications?

A: Yes, both the X4163PIZ and MIC1232NY operate across the industrial temperature range of -40°C to 85°C (TA), making them suitable for industrial and commercial environments.

Q: What are the packaging and mounting considerations?

A: Both devices are housed in 8-DIP packages with 0.300" (7.62mm) pitch and utilize through-hole mounting technology. PCB layouts designed for the X4163PIZ require no modification to accommodate the MIC1232NY.

Q: Why is the X4163PIZ classified as obsolete?

A: Obsolete status indicates that Renesas Electronics Corporation has discontinued production of this device. The MIC1232NY, maintained in active production by Microchip Technology, provides continued availability for supervisor functionality in this package format.

Q: Are there compliance differences between these parts?

A: No. Both the X4163PIZ and MIC1232NY are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards for hazardous substance restrictions and chemical compliance.
