ISO7762DWR Equivalent & Substitute Parts

Part Overview

The ISO7762DWR is a General Purpose Digital Isolator manufactured by Texas Instruments, featuring 5000Vrms isolation voltage and 6 channels with 100Mbps data rate capability. This component operates across a wide temperature range (-55°C to 125°C) and is housed in a 16-SOIC surface mount package. The part is currently in active production status with ROHS3 compliance and REACH unaffected classification. Substitute parts are identified when design requirements necessitate alternative packaging formats or inventory sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The ISO7762FDWR is classified as a parametric equivalent to the ISO7762DWR. Substitution is valid based on the following criteria:

All electrical parameters are identical, including isolation voltage (5000Vrms), channel configuration (6 channels with 4/2 input distribution), data rate (100Mbps), common mode transient immunity (85kV/µs), propagation delay (16ns maximum for both rising and falling edges), and supply voltage range (2.25V to 5.5V).

The mechanical specification remains unchanged: both parts utilize the 16-SOIC (0.295", 7.50mm Width) surface mount package with identical pinout and footprint compatibility.

Manufacturing and compliance attributes are equivalent: both parts are produced by Texas Instruments in the ISO776x series, maintain active product status, comply with ROHS3 standards, and carry identical moisture sensitivity classification (MSL 2, 1 Year).

The primary distinction between these parts is packaging format: ISO7762DWR is supplied in standard packaging, while ISO7762FDWR is available in Cut Tape (CT) and Digi-Reel® format. This difference affects inventory management and automated assembly processes but does not alter component functionality or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both ISO7762DWR and ISO7762FDWR are suitable for applications requiring 5000Vrms digital isolation with 6-channel configuration and 100Mbps data rate capability. Selection between these parts is determined by supply chain and assembly process requirements rather than electrical performance.

The ISO7762DWR is appropriate for standard procurement and manual assembly workflows. The ISO7762FDWR, supplied in Cut Tape and Digi-Reel format, is optimized for high-volume automated pick-and-place assembly operations and continuous reel-based manufacturing processes.

Both parts maintain active production status with identical compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 classification). Substitution between these parts does not require design modification, PCB layout changes, or firmware updates. Thermal and electrical performance characteristics remain identical across the full operating temperature range (-55°C to 125°C) and supply voltage range (2.25V to 5.5V).

Frequently Asked Questions (FAQ)

Q: Can ISO7762FDWR be used as a direct replacement for ISO7762DWR in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The ISO7762FDWR can be substituted without PCB redesign, schematic modification, or performance impact. The only difference is packaging format (Cut Tape/Digi-Reel versus standard packaging).

Q: What is the difference between standard packaging and Cut Tape/Digi-Reel format?

A: Standard packaging is suitable for manual assembly and small-volume production. Cut Tape and Digi-Reel format supplies components on continuous tape reels, optimized for automated assembly equipment and high-volume manufacturing. Both formats contain identical components with identical electrical specifications.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts operate identically across the full temperature range (-55°C to 125°C) and supply voltage range (2.25V to 5.5V). Propagation delay, common mode transient immunity, data rate, and all other electrical parameters are identical.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both ISO7762DWR and ISO7762FDWR are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level (MSL 2, 1 Year) is identical for both parts.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably in the same design and production run. However, packaging format differences may require separate handling procedures in automated assembly workflows.

Q: What is the base product number for these parts?

A: The base product number is ISO7762. Both ISO7762DWR and ISO7762FDWR are variants of this base product, differentiated by packaging format only.
