ISO7763DBQR Equivalent & Substitute Parts

Part Overview

The ISO7763DBQR 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 of unidirectional isolation with 100Mbps data rate capability and operates across a wide temperature range of -55°C to 125°C. The device is actively produced and ROHS3 compliant, making it suitable for industrial and consumer applications requiring reliable signal isolation. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product series.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISO7763DBQR is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating: 3000Vrms
• Channel configuration: 6 channels, unidirectional
• Data rate: 100Mbps
• Common mode transient immunity: 85kV/µs minimum
• Supply voltage range: 2.25V to 5.5V
• Package type: 16-SSOP with 0.154" width (3.90mm)
• Operating temperature range: -55°C to 125°C
• Technology platform: Capacitive coupling within ISO776x series
• Compliance: ROHS3 compliant, active product status

The ISO7763FDBQR meets all specified parameters and is classified as a parametric equivalent within the same product series and manufacturing platform.

Frequently Asked Questions (FAQ)

Q: Can ISO7763FDBQR be used as a direct replacement for ISO7763DBQR?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, isolation ratings, channel configuration, data rates, timing specifications, supply voltage ranges, operating temperature ranges, and package dimensions. They are interchangeable at the circuit level.

Q: Are there differences in isolation voltage or data rate between these parts?

A: No. Both the ISO7763DBQR and ISO7763FDBQR provide 3000Vrms isolation and 100Mbps data rate with identical common mode transient immunity of 85kV/µs.

Q: Do both parts use the same package type?

A: Yes. Both devices are packaged in 16-SSOP with 0.154" width (3.90mm), ensuring identical PCB footprint and mounting requirements.

Q: Are there compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and maintain identical moisture sensitivity levels (MSL 2, 1 Year).

Q: What is the difference between the part numbers ISO7763DBQR and ISO7763FDBQR?

A: The difference lies in the packaging format designation within the part number suffix. Both parts are from the same ISO776x series and share identical electrical and mechanical specifications. The variation reflects different packaging or distribution formats from Texas Instruments.
