IL 017E Digital Isolator 2500Vrms 4-Channel Equivalent & Substitute Parts

Part Overview

The IL 017E is a general-purpose digital isolator manufactured by NVE Corp, part of the IsoLoop® IL01x series. This component provides galvanic isolation at 2500Vrms across four channels using magnetic coupling technology. The device operates at 10Mbps data rate with 30kV/µs common mode transient immunity, housed in a 16-SOIC surface mount package. The IL 017E is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the IL 017E becomes unavailable due to supply constraints, end-of-life status, or when alternative manufacturers' components meet or exceed the electrical and mechanical specifications required for the application.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parameter matching across five critical dimensions:

1. Isolation Voltage Compatibility: Substitute parts must maintain minimum 2500Vrms isolation. Parts with higher isolation ratings (3750Vrms, 5000Vrms) are acceptable as they exceed the requirement.

2. Channel Configuration: All substitutes must provide 4-channel configuration with 3/1 unidirectional input-output arrangement to maintain circuit compatibility.

3. Package Compatibility: All substitutes must use 16-SOIC (0.295", 7.50mm Width) surface mount package for PCB layout compatibility.

4. Data Rate Requirement: Substitutes must support minimum 10Mbps operation. Higher data rates (90Mbps, 150Mbps) are acceptable.

5. Common Mode Transient Immunity: Substitutes must support minimum 30kV/µs CMTI. Lower CMTI ratings (25kV/µs) represent a reduction in performance margin and are not acceptable substitutes. Higher ratings (75kV/µs) are acceptable.

Compliance Requirements: All substitutes must maintain RoHS3 compliance and active product status.

Engineering Selection Recommendations

Tier 1 - Direct Functional Equivalents (Recommended Primary Substitutes):

ADUM1401BRWZ and ADUM2401BRIZ represent the closest functional equivalents to the IL 017E. Both devices maintain 4-channel configuration, 10Mbps data rate, 16-SOIC package, and tube packaging. ADUM1401BRWZ provides 2500Vrms isolation matching the IL 017E specification, while ADUM2401BRIZ provides enhanced 5000Vrms isolation. Both are active products with RoHS3 compliance and high inventory availability (9335 and 1900 units respectively).

Tier 2 - Enhanced Performance Substitutes:

ADUM141D1BRWZ-RL and ADUM141D0BRWZ-RL offer superior performance characteristics with 3750Vrms isolation, 150Mbps data rate, and 75kV/µs CMTI. These components exceed IL 017E specifications across multiple parameters and are suitable for applications requiring higher performance margins. ADUM141D1BRWZ-RL has exceptional inventory availability (25300 units) in Cut Tape/Digi-Reel packaging.

Tier 3 - Lower Data Rate Alternatives:

ADUM1401ARWZ-RL and ADUM2401ARIZ-RL operate at 1Mbps data rate. These are suitable only for applications where 10Mbps operation is not required. Both maintain 2500Vrms and 5000Vrms isolation respectively with high inventory levels.

Tier 4 - Automotive Grade Option:

ADUM1401WTRWZ is designated for automotive applications with extended temperature range (-40°C to 125°C) and MSL 3 rating. This variant is appropriate for automotive or industrial environments requiring higher temperature operation.

Packaging Considerations:

The IL 017E is supplied in Tube packaging. Direct packaging equivalents include ADUM1401BRWZ, ADUM141D1BRWZ, and ADUM2401BRIZ (all Tube). For applications accepting alternative packaging, Cut Tape/Digi-Reel variants (ADUM1401CRWZ-RL, ADUM141D1BRWZ-RL, ADUM2401BRWZ-RL) offer higher inventory availability.

Compliance Status:

All listed substitutes maintain RoHS3 compliance and active product status, meeting regulatory requirements equivalent to the IL 017E.

Frequently Asked Questions (FAQ)

Q1: Can ADUM1401ARWZ-RL replace IL 017E in all applications?

ADUM1401ARWZ-RL maintains identical isolation voltage (2500Vrms), channel configuration (4-channel, 3/1), and package (16-SOIC). However, it operates at 1Mbps data rate compared to IL 017E's 10Mbps. Substitution is valid only for applications where 1Mbps operation meets system requirements. Additionally, CMTI is reduced to 25kV/µs versus IL 017E's 30kV/µs.

Q2: What is the difference between ADUM1401BRWZ and ADUM2401BRIZ?

Both devices operate at 10Mbps with identical propagation delay (50ns/50ns) and pulse width distortion (3ns). The primary difference is isolation voltage: ADUM1401BRWZ provides 2500Vrms (matching IL 017E), while ADUM2401BRIZ provides 5000Vrms. ADUM2401BRIZ is suitable when higher isolation margin is required. Both have identical supply voltage range (2.7V-5.5V) and operating temperature (-40°C to 105°C).

Q3: Why do some substitutes show lower CMTI (25kV/µs) than IL 017E (30kV/µs)?

CMTI specification indicates the rate at which common-mode voltage can change without causing errors. IL 017E specifies 30kV/µs minimum. Analog Devices iCoupler® ADUM1401 and ADUM2401 series specify 25kV/µs. This represents a 5kV/µs reduction in performance margin. Substitution with lower CMTI is not recommended for applications operating near the IL 017E's CMTI specification limit.

Q4: Is ADUM141D1BRWZ-RL a suitable substitute despite higher specifications?

ADUM141D1BRWZ-RL exceeds IL 017E specifications in isolation voltage (3750Vrms vs 2500Vrms), data rate (150Mbps vs 10Mbps), and CMTI (75kV/µs vs 30kV/µs). Higher specifications do not create incompatibility; the device is pin-compatible in 16-SOIC package and maintains 4-channel configuration. This substitute is appropriate when enhanced performance margins are beneficial. Note: operating temperature extends to 125°C and MSL rating is 3 (168 hours).

Q5: What packaging options are available for substitutes?

IL 017E is supplied in Tube packaging. Equivalent tube-packaged substitutes include ADUM1401BRWZ, ADUM141D1BRWZ, and ADUM2401BRIZ. Cut Tape/Digi-Reel variants (ADUM1401CRWZ-RL, ADUM141D1BRWZ-RL, ADUM2401BRWZ-RL) and Tape & Reel variant (ADUM2401ARIZ-RL) are available with higher inventory levels. Packaging selection depends on assembly process requirements and volume.

Q6: Can IL 017E be replaced with ADUM1401WTRWZ in non-automotive applications?

ADUM1401WTRWZ is designated as automotive grade with extended temperature range (-40°C to 125°C). It maintains 2500Vrms isolation, 10Mbps data rate, and 16-SOIC package. The automotive designation does not preclude use in non-automotive applications. However, MSL rating is 3 (168 hours) versus IL 017E's MSL 1 (unlimited), requiring moisture control during storage and handling.

Q7: What is the significance of the "-RL" suffix in part numbers?

The "-RL" suffix indicates Digi-Reel® packaging format, a tape and reel configuration optimized for automated assembly. Parts with "-RL" suffix (ADUM1401ARWZ-RL, ADUM1401CRWZ-RL, ADUM141D0BRWZ-RL, ADUM141D1BRWZ-RL, ADUM2401ARIZ-RL, ADUM2401BRWZ-RL) are supplied on continuous reels. This packaging format typically offers higher inventory availability and is preferred for high-volume production.

Q8: Are all substitutes RoHS3 compliant?

All listed substitute parts maintain RoHS3 compliance status, meeting regulatory requirements equivalent to IL 017E. REACH status is either "REACH Unaffected" or equivalent, indicating compliance with chemical substance regulations.

Q9: Which substitute offers the best inventory availability?

ADUM141D1BRWZ-RL has the highest inventory level at 25,300 units. ADUM1401ARWZ-RL follows with 10,200 units, and ADUM1401BRWZ with 9,335 units. For immediate availability, these three options are recommended.

Q10: Can substitutes operate across the full IL 017E temperature range (-40°C to 100°C)?

All listed substitutes support minimum -40°C to 100°C operation. Most extend to 105°C or 125°C, providing additional temperature margin. ADUM1401WTRWZ extends to 125°C. No substitute has a lower maximum operating temperature than IL 017E, ensuring thermal compatibility.
