ISO7762FDBQR Equivalent & Substitute Parts

Part Overview

The ISO7762FDBQR is a general purpose digital isolator manufactured by Texas Instruments, designed for applications requiring galvanic isolation at 3000Vrms. This capacitive coupling isolator provides 6 channels with 100Mbps data rate and 85kV/µs common mode transient immunity in a 16-SSOP surface mount package. The part is currently in active production status with ROHS3 compliance and is suitable for industrial and consumer isolation applications. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product series.

Substitute Part Grouping Explanation

Substitution of the ISO7762FDBQR 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
• Package type: 16-SSOP surface mount
• Supply voltage range: 2.25V ~ 5.5V
• Operating temperature range: -55°C ~ 125°C
• Technology platform: Capacitive coupling within ISO776x series

The ISO7762DBQR meets all these parameters and is classified as a parametric equivalent within the same product series and technology platform.

Parameter Comparison

Engineering Selection Recommendations

Both the ISO7762FDBQR and ISO7762DBQR are active production parts from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and packaging format (Cut Tape or Digi-Reel). Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and consumer applications. The MSL rating of 2 (1 Year) applies to both parts, requiring standard moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can ISO7762DBQR be used as a direct replacement for ISO7762FDBQR?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, isolation voltage, channel configuration, data rate, and package specifications. They are interchangeable in applications designed for the ISO7762FDBQR.

Q: What determines substitution eligibility for digital isolators in the ISO776x series?

A: Substitution is valid when the following parameters match: isolation voltage rating, number of channels, channel configuration, data rate, common mode transient immunity, supply voltage range, operating temperature range, and package type. All these parameters are identical between the ISO7762FDBQR and ISO7762DBQR.

Q: Are there differences in packaging between these two parts?

A: Both parts are supplied in 16-SSOP surface mount packages with identical physical dimensions (0.154", 3.90mm Width). The packaging format options (Cut Tape or Digi-Reel) do not affect electrical performance or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ISO7762FDBQR and ISO7762DBQR are ROHS3 compliant, REACH unaffected, and carry the same MSL rating of 2 (1 Year). They meet identical regulatory and environmental requirements.

Q: What is the significance of the different part number suffixes (FD vs. DB)?

A: The suffix designates the packaging format. FD indicates Cut Tape packaging, while DB indicates Digi-Reel packaging. The electrical and functional specifications remain identical regardless of packaging format.
