IL 712-2 Digital Isolator: Equivalent & Substitute Parts

Part Overview

The IL 712-2 is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, part of the IsoLoop® series. This component provides 2500Vrms isolation across 2 channels with 110Mbps data rate and 100kV/µs common mode transient immunity. The IL 712-2 is classified as Active product status and utilizes Giant Magnetoresistive (GMR) technology for isolation. Substitute parts are identified when design requirements necessitate alternative packaging formats, enhanced compliance certifications, different channel configurations, or cross-manufacturer solutions while maintaining core electrical performance parameters.

Substitute Part Grouping Explanation

Substitute parts for the IL 712-2 are classified into two categories based on allowed electrical and mechanical parameters:

Direct Substitutes (Identical Electrical & Mechanical Specifications):

• IL 712-2E: Identical electrical performance and package configuration. Differentiation exists only in packaging format (Tube vs. standard) and RoHS compliance status (ROHS3 Compliant vs. RoHS non-compliant).

Parametric Equivalents (Reduced Channel Count):

• IL 710-2 and IL 710-2E: These parts maintain identical isolation voltage (2500Vrms), data rate (110Mbps), CMTI (100kV/µs), propagation delay, pulse width distortion, supply voltage range, operating temperature, and package configuration. The critical difference is channel count: 1 channel versus 2 channels in the IL 712-2. These are suitable for applications requiring single-channel isolation.

Cross-Manufacturer Equivalent (Different CMTI Performance):

• HCPL-9031-000E (Broadcom Limited): Provides 2-channel configuration matching the IL 712-2 with identical isolation voltage, data rate, propagation delay, pulse width distortion, supply voltage, and package. The CMTI specification differs (15kV/µs vs. 100kV/µs), and operating temperature range is extended (-55°C ~ 125°C vs. -40°C ~ 100°C). RoHS3 compliance is confirmed.

Parameter Comparison

Engineering Selection Recommendations

IL 712-2E Selection Criteria: IL 712-2E is the direct substitute for IL 712-2 when ROHS3 compliance is required. Both parts maintain identical electrical specifications, channel configuration, and package format. The IL 712-2E is suitable for applications where regulatory compliance with RoHS3 standards is mandatory. Inventory availability is higher for IL 712-2E (1423 Pcs vs. 936 Pcs).

IL 710-2 / IL 710-2E Selection Criteria: IL 710-2 and IL 710-2E are suitable substitutes when single-channel isolation is sufficient for the application. These parts maintain all critical electrical parameters (isolation voltage, data rate, CMTI, propagation delay, pulse width distortion, supply voltage, and operating temperature) as the IL 712-2. IL 710-2E is selected when ROHS3 compliance is required; IL 710-2 is selected for non-compliant applications. IL 710-2E offers the highest inventory availability (2650 Pcs).

HCPL-9031-000E Selection Criteria: HCPL-9031-000E (Broadcom Limited) is a cross-manufacturer substitute maintaining 2-channel configuration and identical isolation voltage, data rate, propagation delay, pulse width distortion, and supply voltage specifications. This part is selected when extended operating temperature range (-55°C ~ 125°C) is required or when cross-manufacturer sourcing is necessary. ROHS3 compliance is confirmed. The CMTI specification (15kV/µs) is lower than the IL 712-2 (100kV/µs); applications with high common mode transient requirements must evaluate this parameter. Inventory availability is significantly higher (23947 Pcs).

Frequently Asked Questions (FAQ)

Q: Can IL 712-2E directly replace IL 712-2 in existing designs? A: Yes. IL 712-2E is a direct substitute with identical electrical specifications, channel count (2), and 8-DIP package configuration. The only differences are packaging format (Tube) and RoHS compliance status (ROHS3 Compliant). No circuit modifications are required.

Q: What is the primary difference between IL 712-2 and IL 710-2? A: The primary difference is channel count. IL 712-2 provides 2 isolated channels, while IL 710-2 provides 1 isolated channel. All other electrical parameters (isolation voltage, data rate, CMTI, propagation delay, pulse width distortion, supply voltage, operating temperature) and the 8-DIP package are identical.

Q: Can HCPL-9031-000E replace IL 712-2 in applications requiring high common mode transient immunity? A: HCPL-9031-000E has a CMTI specification of 15kV/µs, which is lower than IL 712-2's 100kV/µs specification. Applications requiring 100kV/µs CMTI performance must not use HCPL-9031-000E as a substitute. HCPL-9031-000E is suitable only for applications with CMTI requirements of 15kV/µs or lower.

Q: Are all substitute parts available in the same 8-DIP package? A: Yes. All substitute parts (IL 712-2E, IL 710-2, IL 710-2E, and HCPL-9031-000E) use the 8-DIP (0.300", 7.62mm) through-hole package. Pin-to-pin compatibility exists for parts with matching channel configurations (IL 712-2, IL 712-2E, and HCPL-9031-000E for 2-channel applications).

Q: Which substitute part has the best inventory availability? A: HCPL-9031-000E (Broadcom Limited) has the highest inventory availability at 23947 Pcs. Among NVE Corp parts, IL 710-2E has the highest availability at 2650 Pcs.

Q: What is the operating temperature difference between IL 712-2 and HCPL-9031-000E? A: IL 712-2 operates from -40°C to 100°C, while HCPL-9031-000E operates from -55°C to 125°C. HCPL-9031-000E provides an extended temperature range suitable for industrial and automotive applications requiring wider temperature specifications.

Q: Are all substitute parts RoHS3 compliant? A: No. IL 712-2 and IL 710-2 are RoHS non-compliant. IL 712-2E, IL 710-2E, and HCPL-9031-000E are ROHS3 Compliant. Select the -E variants or HCPL-9031-000E when RoHS3 compliance is required.
