ISO7330FCDWR Digital Isolator 3000Vrms 3-Channel Equivalent & Substitute Parts

Part Overview

The ISO7330FCDWR is a general purpose digital isolator manufactured by Texas Instruments, featuring 3000Vrms isolation voltage and 3-channel unidirectional configuration. This capacitive coupling isolator operates at 25Mbps data rate with 25kV/µs common mode transient immunity, housed in a 16-SOIC surface mount package. The part is active in production status and ROHS3 compliant. Substitute parts are identified to address inventory availability, packaging format requirements, or automotive qualification needs while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ISO7330FCDWR is determined by matching the following critical parameters: isolation voltage (3000Vrms), channel count and configuration (3 unidirectional channels), data rate (25Mbps), common mode transient immunity (25kV/µs), supply voltage range (3V–5.5V), operating temperature range (-40°C to 125°C), package type (16-SOIC), and technology platform (capacitive coupling). All identified substitutes maintain these core electrical specifications and mechanical compatibility. Packaging format and automotive qualification status are secondary differentiators that do not affect functional interchangeability in standard applications.

Engineering Selection Recommendations

All three parts—ISO7330FCDWR, ISO7330CQDWRQ1, and ISO7330FCQDWRQ1—are active production components with identical electrical performance and mechanical compatibility. Selection between them is based on application requirements and supply chain factors:

ISO7330FCDWR is the standard industrial-grade variant supplied in Tape & Reel packaging format, suitable for high-volume manufacturing environments requiring standard packaging.

ISO7330CQDWRQ1 and ISO7330FCQDWRQ1 are automotive-qualified variants meeting AEC-Q100 standards. These parts are required for automotive applications or systems subject to automotive reliability and qualification requirements. ISO7330CQDWRQ1 is supplied in Tape & Reel format, while ISO7330FCQDWRQ1 is supplied in Cut Tape and Digi-Reel format for applications requiring alternative packaging configurations.

All parts maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 2, 1 Year). Functional interchangeability is complete across all three variants within their respective application domains.

Frequently Asked Questions (FAQ)

Q: Can ISO7330CQDWRQ1 or ISO7330FCQDWRQ1 be used as direct replacements for ISO7330FCDWR?

A: Yes. All three parts share identical electrical specifications, including isolation voltage, channel configuration, data rate, timing parameters, and supply voltage range. The automotive-qualified variants (ISO7330CQDWRQ1 and ISO7330FCQDWRQ1) are functionally interchangeable with the standard variant (ISO7330FCDWR) in non-automotive applications. However, the standard variant should not be used in automotive applications requiring AEC-Q100 qualification.

Q: What is the difference between ISO7330CQDWRQ1 and ISO7330FCQDWRQ1?

A: Both parts are automotive-qualified with identical electrical performance. The primary difference is packaging format: ISO7330CQDWRQ1 is supplied in Tape & Reel (TR) format, while ISO7330FCQDWRQ1 is supplied in Cut Tape (CT) and Digi-Reel format. Selection depends on manufacturing equipment compatibility and supply chain requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. ISO7330FCDWR, ISO7330CQDWRQ1, and ISO7330FCQDWRQ1 are all ROHS3 compliant with identical moisture sensitivity levels (MSL 2, 1 Year).

Q: What packaging formats are available?

A: ISO7330FCDWR and ISO7330CQDWRQ1 are supplied in Tape & Reel (TR) format. ISO7330FCQDWRQ1 is supplied in Cut Tape (CT) and Digi-Reel format. Packaging selection should align with manufacturing equipment specifications and assembly line requirements.

Q: Can these parts be used interchangeably in automotive applications?

A: Only ISO7330CQDWRQ1 and ISO7330FCQDWRQ1 are qualified for automotive applications under AEC-Q100 standards. ISO7330FCDWR is not automotive-qualified and should not be used in automotive systems requiring qualification compliance.
