IL 715T-3 General Purpose Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 715T-3 is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, operating at 2500Vrms isolation voltage with 4 channels, 110Mbps data rate, and 100kV/µs common mode transient immunity. The device utilizes Giant Magnetoresistive (GMR) technology in a 16-SOIC surface mount package. This part is active and currently in production. Equivalent and substitute parts are identified to support design flexibility, inventory management, and supply chain continuity when the primary part number becomes unavailable or when alternative compliance certifications are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IL 715T-3 is determined by the following critical parameters: isolation voltage (2500Vrms), number of channels (4), channel type (unidirectional), data rate (110Mbps minimum), propagation delay (15ns maximum), pulse width distortion (3ns maximum), supply voltage range (3V ~ 5.5V), and package compatibility (16-SOIC surface mount).

Direct Equivalent (Packaging Variant): IL 715T-3E is a direct equivalent differing only in packaging format (Tube vs. standard packaging) and RoHS compliance status. All electrical and thermal specifications are identical.

Similar Substitutes (Parameter Variations): HCPL-090J-000E and HCPL-900J-000E are Broadcom Limited alternatives that maintain core isolation voltage, channel count, data rate, propagation delay, and pulse width distortion specifications. These parts differ in common mode transient immunity (15kV/µs vs. 100kV/µs), operating temperature range extension (-55°C vs. -40°C minimum), and package dimensions. HCPL-900J differs in RoHS compliance status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

IL 715T-3E: Select this part when RoHS3 compliance is required and packaging format (Tube) is acceptable. Electrical performance is identical to IL 715T-3. This is the preferred direct replacement for new designs requiring regulatory compliance.

HCPL-090J-000E: Select this Broadcom part when RoHS3 compliance is mandatory and the application operates within the -40°C to 125°C temperature range. Package dimensions (0.154", 3.90mm width) match the IL 715T-3 footprint. Common mode transient immunity is reduced to 15kV/µs; verify application requirements before selection.

HCPL-900J-000E: Select this Broadcom part when RoHS3 compliance is required and extended low-temperature operation (-55°C minimum) is necessary. Package dimensions differ (0.295", 7.50mm width); PCB layout modification is required. Common mode transient immunity is 15kV/µs.

HCPL-900J: Select only when RoHS compliance is not required and extended temperature range (-55°C to 125°C) is needed. Package dimensions differ from IL 715T-3; PCB redesign is necessary. This part is not recommended for new designs due to non-compliant RoHS status.

Frequently Asked Questions (FAQ)

Q: Can IL 715T-3E be used as a direct drop-in replacement for IL 715T-3? A: Yes. IL 715T-3E is electrically and functionally identical to IL 715T-3. The only differences are packaging format (Tube) and RoHS3 compliance status. No circuit modifications are required.

Q: What is the primary difference between IL 715T-3 and the Broadcom HCPL-090J-000E? A: The primary difference is common mode transient immunity: IL 715T-3 specifies 100kV/µs while HCPL-090J-000E specifies 15kV/µs. Applications requiring high CMTI performance must verify compatibility before substitution. Package dimensions are identical (0.154", 3.90mm width).

Q: Why do HCPL-900J and HCPL-900J-000E have different package dimensions than IL 715T-3? A: HCPL-900J and HCPL-900J-000E use a wider 16-SOIC package (0.295", 7.50mm width) compared to the narrower 16-SOIC package (0.154", 3.90mm width) of IL 715T-3. PCB layout and footprint modifications are required for these substitutes.

Q: Is HCPL-900J suitable for new product designs? A: HCPL-900J is not recommended for new designs. It carries RoHS non-compliant status. HCPL-900J-000E is the RoHS3 compliant equivalent and should be selected for new designs requiring Broadcom components.

Q: Can I substitute IL 715T-3 with HCPL-090J-000E in a high-speed switching application? A: Substitution is possible if the application does not require common mode transient immunity exceeding 15kV/µs. Verify that the reduced CMTI specification (15kV/µs vs. 100kV/µs) does not compromise circuit performance. All other timing parameters (propagation delay, pulse width distortion, rise/fall time) are identical.

Q: What compliance certifications should I verify before selecting a substitute part? A: Verify RoHS compliance status based on your product requirements. IL 715T-3E, HCPL-090J-000E, and HCPL-900J-000E are ROHS3 compliant. IL 715T-3 and HCPL-900J are RoHS non-compliant. All parts are REACH unaffected and carry appropriate ECCN classifications.

Q: Are all substitute parts available in the same packaging format? A: No. IL 715T-3 and IL 715T-3E are available in standard and Tube packaging respectively. HCPL-090J-000E is available in Tube packaging with matching 0.154" package width. HCPL-900J-000E and HCPL-900J are available in Tube and standard packaging respectively, but with wider 0.295" package dimensions.
