IL 711-2 General Purpose Digital Isolator 2500Vrms 2-Channel Equivalent & Substitute Parts

Part Overview

The IL 711-2 is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, part of the IsoLoop® series. This component provides 2500Vrms isolation across 2 unidirectional channels with 110Mbps data rate and 100kV/µs common mode transient immunity in an 8-DIP through-hole package. The IL 711-2 is classified as Active product status. Equivalent and substitute parts are identified for applications requiring alternative packaging options, enhanced compliance certifications, or parametric variations in channel configuration while maintaining core isolation and performance specifications.

Substitute Part Grouping Explanation

Substitute parts for the IL 711-2 are grouped based on the following substitution criteria:

Direct Packaging Equivalent: IL 711-2E maintains identical electrical specifications, channel configuration (2 channels), isolation voltage (2500Vrms), data rate (110Mbps), and CMTI (100kV/µs). The primary difference is packaging format (Tube vs. standard packaging) and RoHS compliance status (ROHS3 Compliant vs. RoHS non-compliant).

Parametric Equivalent - Reduced Channel Count: IL 710-2 and IL 710-2E provide 1-channel configuration instead of 2 channels. All other electrical parameters remain identical: 2500Vrms isolation, 110Mbps data rate, 100kV/µs CMTI, 15ns propagation delay, and 8-DIP package. These parts are suitable for applications requiring single-channel isolation.

Cross-Manufacturer Equivalent: HCPL-9030 and HCPL-9030-000E (Broadcom Limited) provide 2-channel configuration matching the IL 711-2 channel count and 2500Vrms isolation. Key parameter differences include reduced CMTI specification (15kV/µs vs. 100kV/µs) and extended operating temperature range (-55°C ~ 125°C vs. -40°C ~ 100°C). Data rate specification uses MBd notation (110MBd) equivalent to 110Mbps.

Engineering Selection Recommendations

For Direct Replacement with Enhanced Compliance: IL 711-2E is the direct equivalent when ROHS3 compliance is required. This part maintains all electrical and mechanical specifications of the IL 711-2 while providing RoHS3 certification. Selection is appropriate for applications with regulatory compliance requirements.

For Single-Channel Applications: IL 710-2 and IL 710-2E provide identical isolation voltage, data rate, and CMTI specifications in a 1-channel configuration. IL 710-2E is selected when ROHS3 compliance is mandatory. These parts are suitable for applications requiring only single-channel isolation while maintaining 2500Vrms isolation performance.

For Extended Temperature Range Applications: HCPL-9030 and HCPL-9030-000E support operating temperatures from -55°C to 125°C, compared to -40°C to 100°C for NVE parts. These Broadcom components maintain 2-channel configuration and 2500Vrms isolation. HCPL-9030-000E provides ROHS3 compliance. Selection is appropriate for applications requiring extended temperature operation. Note: CMTI specification is reduced to 15kV/µs.

Compliance Considerations: All parts listed maintain Active product status. ROHS3-compliant variants (IL 711-2E, IL 710-2E, HCPL-9030-000E) are selected for applications subject to RoHS regulations. All parts are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can IL 711-2E replace IL 711-2 in existing designs? A: Yes. IL 711-2E is a direct equivalent with identical electrical specifications, channel configuration, and package. The primary difference is ROHS3 compliance certification and packaging format (Tube). Pin-to-pin compatibility is maintained.

Q: What is the difference between IL 711-2 and IL 710-2? A: IL 710-2 provides 1-channel isolation instead of 2 channels. All other specifications remain identical: 2500Vrms isolation, 110Mbps data rate, 100kV/µs CMTI, and 8-DIP package. Selection depends on application requirements for channel count.

Q: Can HCPL-9030 be used instead of IL 711-2? A: HCPL-9030 maintains 2-channel configuration, 2500Vrms isolation, and identical propagation delay specifications. However, CMTI is reduced from 100kV/µs to 15kV/µs, and operating temperature range is extended to -55°C ~ 125°C. Substitution is valid only if the reduced CMTI specification is acceptable for the application.

Q: What does ROHS3 compliance mean for component selection? A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements. Parts designated as ROHS3 Compliant (IL 711-2E, IL 710-2E, HCPL-9030-000E) are selected for applications subject to RoHS regulations or customer requirements.

Q: Are all listed parts in the same 8-DIP package? A: Yes. All substitute parts use 8-DIP (0.300", 7.62mm) through-hole package with identical pin spacing and mounting requirements.

Q: What is the significance of GMR technology in these isolators? A: GMR (Giant Magnetoresistive) technology is the isolation method used in all listed parts. This technology provides the specified isolation voltage and CMTI performance characteristics.

Q: How does CMTI affect component selection? A: CMTI (Common Mode Transient Immunity) specifies the maximum rate of change of common-mode voltage the isolator can withstand. NVE parts provide 100kV/µs, while Broadcom HCPL-9030 series provides 15kV/µs. Applications with high dV/dt requirements require the higher CMTI specification.

Q: Can IL 710-2E be used in a 2-channel application? A: No. IL 710-2E provides only 1 isolated channel. Applications requiring 2-channel isolation must use IL 711-2, IL 711-2E, HCPL-9030, or HCPL-9030-000E.
