IL 710T-3E Digital Isolator Equivalent & Substitute Parts
Part Overview
The IL 710T-3E is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, part of the IsoLoop® series. This component provides galvanic isolation using Giant Magnetoresistive (GMR) technology with a 2500Vrms isolation voltage rating and unidirectional single-channel architecture. The IL 710T-3E is classified as an active product with full ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).
Equivalent and substitute parts are identified based on matching electrical performance parameters, isolation voltage ratings, data rates, common mode transient immunity specifications, and compatible surface mount packaging. Substitute parts enable design flexibility when the primary part number is unavailable or when alternative compliance certifications are required.

Engineering Selection Recommendations
IL 710T-3E (Primary Part): Select this part number for applications requiring ROHS3 compliance and the highest common mode transient immunity specification (100kV/µs). The IL 710T-3E is actively produced and available in tube packaging format. This part is suitable for designs with strict environmental and regulatory requirements.
IL 710T-3 (Parametric Equivalent): This NVE Corp part provides identical electrical performance to the IL 710T-3E but carries RoHS non-compliant status. Selection of IL 710T-3 is appropriate only when RoHS compliance is not a design requirement. The part is actively produced and functionally interchangeable at the circuit level.
HCPL-0900-000E (Broadcom Limited, ROHS3 Compliant): This Broadcom part offers ROHS3 compliance matching the IL 710T-3E and provides an extended operating temperature range (-55°C to 125°C). The primary electrical difference is reduced common mode transient immunity (15kV/µs vs. 100kV/µs). HCPL-0900-000E is suitable for applications where the lower CMTI specification is acceptable and extended low-temperature operation is required. This part is actively produced with high inventory availability (86,400 units).
HCPL-0900-500E (Broadcom Limited, ROHS3 Compliant, Tape & Reel): This variant provides identical electrical specifications to HCPL-0900-000E with ROHS3 compliance and extended temperature range. The packaging format is Tape & Reel (TR) rather than tube, making it suitable for high-volume automated assembly processes. Selection is appropriate when production volume justifies tape and reel packaging and lower CMTI specification is acceptable.
HCPL-0900 (Broadcom Limited, RoHS Non-Compliant): This base Broadcom part number provides functional equivalence with reduced CMTI specification (15kV/µs) and RoHS non-compliant status. It is suitable only for applications where RoHS compliance is not required and lower CMTI is acceptable. Tube packaging is available.
Frequently Asked Questions (FAQ)
Q: Can IL 710T-3 be used as a direct replacement for IL 710T-3E?
A: IL 710T-3 provides identical electrical performance and package compatibility. The primary difference is RoHS compliance status. IL 710T-3 is RoHS non-compliant while IL 710T-3E is ROHS3 compliant. Direct substitution is possible only if RoHS compliance is not a design or regulatory requirement.
Q: What is the key difference between NVE IL 710T-3E and Broadcom HCPL-0900 series parts?
A: The primary electrical difference is common mode transient immunity (CMTI). The IL 710T-3E specifies 100kV/µs minimum CMTI, while all HCPL-0900 variants specify 15kV/µs. All other electrical parameters including isolation voltage, data rate, propagation delay, and supply voltage are identical. The Broadcom parts also offer extended operating temperature range (-55°C to 125°C vs. -40°C to 125°C).
Q: Which substitute part has the best RoHS compliance status?
A: HCPL-0900-000E and HCPL-0900-500E both carry ROHS3 compliance status, matching the IL 710T-3E. HCPL-0900-500E additionally offers Tape & Reel packaging for automated assembly. IL 710T-3 and HCPL-0900 are RoHS non-compliant.
Q: Are all substitute parts available in 8-SOIC package?
A: All substitute parts use 8-SOIC (0.154", 3.90mm Width) surface mount package. Packaging format differs: IL 710T-3E, HCPL-0900, and HCPL-0900-000E are supplied in tube format; HCPL-0900-500E is supplied in Tape & Reel (TR) format. IL 710T-3 packaging format is not specified.
Q: Can HCPL-0900-500E be used in applications requiring 100kV/µs CMTI?
A: No. HCPL-0900-500E specifies 15kV/µs minimum CMTI, which is lower than the IL 710T-3E specification of 100kV/µs. Applications with high common mode transient immunity requirements must use IL 710T-3E or IL 710T-3.
Q: What is the inventory status of substitute parts?
A: IL 710T-3E has 867 units in stock. IL 710T-3 has 962 units. HCPL-0900 has 3,700 units. HCPL-0900-000E has 86,400 units (highest availability). HCPL-0900-500E has 3,277 units.
Q: Are all parts rated for -40°C to 125°C operating temperature?
A: IL 710T-3E and IL 710T-3 are rated -40°C to 125°C. All Broadcom HCPL-0900 variants (HCPL-0900, HCPL-0900-000E, HCPL-0900-500E) are rated -55°C to 125°C, providing extended low-temperature capability.
Q: What is the moisture sensitivity level (MSL) for all parts?
A: All parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
