ISO7841DWWR Equivalent & Substitute Parts

Part Overview

The ISO7841DWWR is a general purpose digital isolator manufactured by Texas Instruments, featuring 5700Vrms isolation voltage and 4 channels with 100Mbps data rate capability. This device is classified as Active product status and utilizes capacitive coupling technology for signal isolation in industrial and communication applications. Substitute parts are identified when design requirements allow for reduced channel count or alternative channel configurations while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISO7841DWWR are qualified based on the following criteria:

Mandatory Matching Parameters:

• Manufacturer: Texas Instruments
• Technology: Capacitive Coupling
• Type: General Purpose
• Voltage - Isolation: 5700Vrms
• Common Mode Transient Immunity (Min): 100kV/µs
• Data Rate: 100Mbps
• Voltage - Supply: 2.25V ~ 5.5V
• Operating Temperature: -55°C ~ 125°C
• Package / Case: 16-SOIC (0.551", 14.00mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Variable Parameters (Allowed Differences):

• Number of Channels: 3 or 4
• Inputs - Side 1/Side 2: Configuration variations
• Packaging: Tape & Reel (TR) or standard packaging

The ISO7830DWWR and ISO7831FDWWR are qualified substitutes because they maintain all mandatory electrical and mechanical parameters while differing only in channel count (3 channels versus 4 channels) and input/output channel distribution.

Parameter Comparison

Engineering Selection Recommendations

Selection between ISO7841DWWR and its substitutes is determined by application channel requirements:

ISO7841DWWR is specified when the application requires 4 isolated channels with 3 inputs on Side 1 and 1 input on Side 2.

ISO7830DWWR is applicable when the application requires 3 isolated channels with all inputs configured on Side 1 (3 inputs, 0 outputs on Side 2).

ISO7831FDWWR is applicable when the application requires 3 isolated channels with 2 inputs on Side 1 and 1 input on Side 2.

All three parts maintain identical electrical performance characteristics including 5700Vrms isolation voltage, 100kV/µs common mode transient immunity, 100Mbps data rate, and identical timing specifications. All parts are Active product status with ROHS3 compliance and Moisture Sensitivity Level 2 (1 Year). Pin-to-pin compatibility within the 16-SOIC package is maintained across all variants.

Frequently Asked Questions (FAQ)

Q: Can ISO7830DWWR or ISO7831FDWWR be used as direct replacements for ISO7841DWWR?

A: Direct replacement is possible only if the application circuit uses 3 or fewer isolated channels. The ISO7841DWWR provides 4 channels; the substitute parts provide 3 channels. If all 4 channels are utilized in the design, substitution is not possible.

Q: What is the difference between ISO7830DWWR and ISO7831FDWWR?

A: Both parts provide 3 isolated channels with identical electrical specifications. The difference is in channel configuration: ISO7830DWWR has 3 inputs on Side 1 and 0 on Side 2, while ISO7831FDWWR has 2 inputs on Side 1 and 1 input on Side 2. Selection depends on the specific input/output distribution required by the application.

Q: Are all three parts pin-compatible?

A: All three parts use the 16-SOIC package with identical physical dimensions (0.551", 14.00mm Width). However, pin functionality differs due to channel count and configuration variations. PCB layout and schematic must be verified for compatibility before substitution.

Q: Do all substitute parts meet the same isolation and timing specifications?

A: Yes. All three parts maintain 5700Vrms isolation voltage, 100kV/µs common mode transient immunity, 100Mbps data rate, 16ns maximum propagation delay, and 4.1ns maximum pulse width distortion.

Q: What is the supply voltage range for these parts?

A: All three parts operate with supply voltage from 2.25V to 5.5V and maintain performance across the operating temperature range of -55°C to 125°C.
