ADG436BN Equivalent & Substitute Parts

Part Overview

The ADG436BN is a 2-circuit IC switch with SPDT (Single Pole Double Throw) configuration and 12Ohm typical on-state resistance, manufactured by Analog Devices Inc. in a 16-DIP through-hole package. The part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across switch circuit topology, multiplexer configuration, and electrical performance within specified operating ranges.

Substitute Part Grouping Explanation

Substitution of the ADG436BN is determined by the following critical parameters:

Switch circuit topology (SPDT required)
Multiplexer configuration (2:1 required)
Number of circuits (2 required)
Supply voltage compatibility (must support the application's voltage range)
On-state resistance (must be acceptable for signal path impedance requirements)
Operating temperature range (must meet application thermal requirements)
Mounting type and package compatibility (through-hole vs. surface mount affects PCB design)

The substitute parts are grouped into two categories:

Direct Equivalent (Package Variant): ADG436BNZ maintains identical electrical specifications and through-hole DIP packaging with active product status and improved compliance documentation.

Functional Equivalents (Performance Variants): ADG1436YRUZ and ADG5436FBCPZ-RL7 provide SPDT 2:1 switch functionality with different on-state resistance, package types, and operating characteristics. These require design evaluation based on specific application requirements.

Engineering Selection Recommendations

ADG436BNZ is the primary direct substitute for ADG436BN. It provides identical electrical specifications and through-hole DIP packaging, eliminating PCB redesign requirements. ADG436BNZ carries active product status with ROHS3 compliance and REACH unaffected certification, making it suitable for new production and long-term availability.

ADG1436YRUZ is a functional equivalent for applications where lower on-state resistance (1.8Ohm vs. 12Ohm) is beneficial and surface-mount packaging is acceptable. This part requires PCB layout modification and operates within a narrower supply voltage range (5V ~ 16.5V single supply). Extended operating temperature range (-40°C ~ 125°C) supports wider thermal environments. ROHS3 compliance and REACH unaffected status are maintained.

ADG5436FBCPZ-RL7 is a functional equivalent for applications requiring higher supply voltage capability (8V ~ 44V single supply) and compact surface-mount packaging. On-state resistance (11.5Ohm) closely matches ADG436BN specifications. This part exhibits higher charge injection (-737pC) and lower crosstalk performance (-73dB @ 1MHz) compared to the original part. Extended operating temperature range and ROHS3 compliance are provided. Moisture sensitivity level MSL 3 requires controlled storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ADG436BNZ be used as a direct replacement for ADG436BN without PCB modification?

A: Yes. ADG436BNZ maintains identical electrical specifications, on-state resistance, supply voltage ranges, and 16-DIP through-hole package dimensions. No circuit redesign is required.

Q: What are the key differences between ADG436BN and ADG1436YRUZ?

A: ADG1436YRUZ provides significantly lower on-state resistance (1.8Ohm vs. 12Ohm) and improved channel-to-channel matching (100mOhm vs. 1Ohm). However, it requires surface-mount PCB layout, operates within a narrower supply voltage range (5V ~ 16.5V vs. 3V ~ 30V), and exhibits slower switch times (120ns/130ns vs. 70ns/60ns). Extended operating temperature range (-40°C ~ 125°C) is provided.

Q: Is ADG5436FBCPZ-RL7 compatible with existing ADG436BN PCB designs?

A: No. ADG5436FBCPZ-RL7 uses surface-mount 16-LFCSP-WQ packaging, requiring complete PCB redesign. On-state resistance (11.5Ohm) is comparable, but supply voltage range extends to 44V, and charge injection is significantly higher (-737pC). This part is suitable for new designs requiring compact packaging and extended voltage capability.

Q: What supply voltage range must be verified when selecting a substitute?

A: The application's required supply voltage must fall within the substitute part's specified range. ADG436BN and ADG436BNZ support 3V ~ 30V (single supply) or ±3V ~ 20V (dual supply). ADG1436YRUZ supports 5V ~ 16.5V (single supply) or ±4.5V ~ 16.5V (dual supply). ADG5436FBCPZ-RL7 supports 8V ~ 44V (single supply) or ±5V ~ 22V (dual supply).

Q: Are all substitute parts RoHS compliant?

A: Yes. ADG436BNZ, ADG1436YRUZ, and ADG5436FBCPZ-RL7 are all ROHS3 compliant with REACH unaffected status.

Q: What is the moisture sensitivity level (MSL) difference between substitute parts?

A: ADG436BN, ADG436BNZ, and ADG1436YRUZ have MSL 1 (unlimited shelf life). ADG5436FBCPZ-RL7 has MSL 3, requiring controlled storage at specified humidity and temperature conditions for 168 hours maximum before soldering.
