ISO7762DBQ Equivalent & Substitute Parts

Part Overview

The ISO7762DBQ is a general purpose digital isolator manufactured by Texas Instruments, designed for applications requiring galvanic isolation up to 3000Vrms across 6 channels. This capacitive coupling technology isolator operates at 100Mbps data rate with 85kV/µs common mode transient immunity, housed in a 16-SSOP surface mount package. The device is currently in active production status with full RoHS3 compliance and REACH unaffected certification. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across all critical isolation, timing, and supply parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISO7762DBQ is determined by strict equivalence across the following critical parameters: isolation voltage rating (3000Vrms), channel configuration (6 channels with 4/2 input distribution), data rate (100Mbps), common mode transient immunity (85kV/µs minimum), propagation delay specifications (16ns maximum for both rising and falling edges), supply voltage range (2.25V to 5.5V), and package form factor (16-SSOP with 3.90mm width). All substitute parts must maintain identical electrical performance within these specifications and use the same surface mount package to ensure PCB layout compatibility and thermal characteristics. Technology platform (capacitive coupling) and operating temperature range (-55°C to 125°C) must also remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both ISO7762DBQ and ISO7762FDBQ are active production devices from Texas Instruments within the ISO776x series. Selection between these parts is based on availability and supply chain considerations rather than functional differences. Both devices maintain full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The identical electrical specifications, timing characteristics, and package form factor ensure direct substitution without circuit redesign or PCB layout modification. Moisture sensitivity level (MSL 2, 1 Year) is equivalent for both parts, requiring identical handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can ISO7762FDBQ replace ISO7762DBQ in existing designs? A: Yes. Both parts are parametrically equivalent across all electrical specifications, timing parameters, and package dimensions. Direct substitution is possible without circuit modification.

Q: Are there differences in isolation voltage or channel configuration? A: No. Both devices provide identical 3000Vrms isolation, 6-channel configuration with 4/2 input distribution, and 100Mbps data rate.

Q: Do these parts require different PCB layouts? A: No. Both use the 16-SSOP package with identical 3.90mm width and pin configuration, ensuring footprint compatibility.

Q: What is the difference between ISO7762DBQ and ISO7762FDBQ part numbers? A: The suffix variation (DBQ vs FDBQ) indicates different manufacturing date codes or tape/reel packaging options from Texas Instruments. Electrical and functional performance remains identical.

Q: Are compliance certifications the same for both parts? A: Yes. Both parts carry RoHS3 compliance and REACH unaffected status with MSL 2 (1 Year) moisture sensitivity rating.

Q: Can these parts be used interchangeably in high-temperature applications? A: Yes. Both devices operate across the full -55°C to 125°C temperature range with identical thermal specifications.
