IL 612-2E Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 612-2E is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, part of the IsoLoop® series. This 2-channel, 2500Vrms rated isolator operates at 100Mbps with 15kV/µs common mode transient immunity in an 8-DIP through-hole package. The product is active and ROHS3 compliant. Substitute parts are identified when design requirements permit reduced channel count, alternative manufacturers, or enhanced performance specifications while maintaining core isolation and electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IL 612-2E are identified based on the following allowed parameters:

Parametric Equivalent (IL 610-2E): Maintains identical isolation voltage (2500Vrms), data rate (100Mbps), CMTI (15kV/µs), propagation delay, supply voltage range, operating temperature, package type, and technology (GMR). The primary difference is reduced channel count (1 channel vs. 2 channels). This part substitutes when single-channel isolation is sufficient for the application.

Similar Manufacturer Part (HCPL-9031-000E): Maintains identical isolation voltage (2500Vrms), CMTI (15kV/µs), propagation delay, supply voltage range, package type, and channel count (2 channels). Differences include higher data rate (110MBd vs. 100Mbps), lower pulse width distortion (3ns vs. 5ns), faster rise/fall times (1ns vs. 2ns), extended operating temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C), and different manufacturer (Broadcom Limited vs. NVE Corp). This part substitutes when enhanced performance specifications and wider temperature operation are acceptable.

Parameter Comparison

Engineering Selection Recommendations

IL 610-2E Selection: Choose this parametric equivalent when the application requires only single-channel isolation. All critical electrical parameters—isolation voltage, CMTI, data rate, propagation delay, and supply voltage—are identical to the IL 612-2E. Both parts are manufactured by NVE Corp, share GMR technology, maintain identical operating temperature range, and are ROHS3 compliant with MSL 1 rating. This substitution reduces component cost and board space when dual-channel functionality is not required.

HCPL-9031-000E Selection: Choose this similar part when enhanced performance specifications and extended operating temperature range are acceptable. The Broadcom HCPL-9031-000E maintains the same isolation voltage, CMTI, propagation delay, and supply voltage as the IL 612-2E while offering higher data rate (110MBd), lower pulse width distortion (3ns), faster rise/fall times (1ns), and wider temperature operation (-55°C ~ 125°C). Both parts retain 2-channel configuration, GMR technology, ROHS3 compliance, and MSL 1 rating. This substitution is suitable for applications requiring improved signal integrity or operation in extended temperature environments.

Frequently Asked Questions (FAQ)

Q: Can IL 610-2E replace IL 612-2E in all applications?

A: IL 610-2E is a parametric equivalent with identical isolation voltage, data rate, CMTI, and propagation delay. It substitutes only when single-channel isolation satisfies the application requirement. If the design requires two isolated channels, IL 610-2E is not suitable.

Q: What are the key differences between IL 612-2E and HCPL-9031-000E?

A: Both maintain 2500Vrms isolation, 15kV/µs CMTI, and 2-channel configuration. HCPL-9031-000E offers higher data rate (110MBd vs. 100Mbps), lower pulse width distortion (3ns vs. 5ns), faster rise/fall times (1ns vs. 2ns), and extended operating temperature (-55°C ~ 125°C vs. -40°C ~ 85°C). The IL 612-2E is manufactured by NVE Corp; HCPL-9031-000E is manufactured by Broadcom Limited.

Q: Are all three parts pin-compatible?

A: IL 612-2E and HCPL-9031-000E share identical 8-DIP (0.300", 7.62mm) package and 2-channel configuration, supporting direct board-level substitution. IL 610-2E uses the same 8-DIP package but has 1-channel configuration, requiring circuit design modification for substitution.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. IL 612-2E, IL 610-2E, and HCPL-9031-000E are all ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are active products. All three are unaffected by REACH regulations.

Q: Which substitute part offers the best performance?

A: HCPL-9031-000E provides enhanced performance with higher data rate (110MBd), lower pulse width distortion (3ns), and faster rise/fall times (1ns). It also supports extended operating temperature range (-55°C ~ 125°C). Selection depends on whether these specifications are required for the specific application.

Q: Can IL 612-2E be used in high-temperature applications?

A: IL 612-2E operates from -40°C to 85°C. For applications requiring operation beyond 85°C, HCPL-9031-000E supports -55°C to 125°C and is the appropriate substitute.
