IL 516E Digital Isolator - Equivalent & Substitute Parts

Part Overview

The IL 516E 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 rating across 4 channels. The IL 516E is classified as an Active product with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when design requirements permit reduction in channel count or when inventory constraints necessitate alternative configurations while maintaining critical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the IL 516E is determined by the following critical parameters that must remain constant across equivalent parts:

Mandatory Matching Parameters:

• Isolation Voltage: 2500Vrms
• Common Mode Transient Immunity: 30kV/µs minimum
• Data Rate: 2Mbps
• Propagation Delay: 25ns maximum (both tpLH and tpHL)
• Pulse Width Distortion: 10ns maximum
• Supply Voltage Range: 3V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Technology: GMR (Giant Magnetoresistive)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Variable Parameters Permitting Substitution:

• Number of Channels (4 channels in IL 516E; 3 channels in IL 514E)
• Channel Configuration (Inputs - Side 1/Side 2: 2/2 in IL 516E; 2/1 in IL 514E)

The IL 514E qualifies as a parametric equivalent because it maintains all mandatory electrical and mechanical specifications while differing only in channel count and input distribution. This substitution is valid only when application requirements do not exceed 3 isolated channels.

Parameter Comparison

Engineering Selection Recommendations

IL 516E Selection Criteria: The IL 516E is the primary choice when applications require 4 isolated channels with 2 inputs on each side of the isolation barrier. This configuration supports bidirectional signal isolation across two independent channel pairs.

IL 514E Selection Criteria: The IL 514E is a valid substitute when application requirements are limited to 3 isolated channels with asymmetric input distribution (2 inputs on Side 1, 1 input on Side 2). Both parts maintain identical electrical performance specifications, isolation ratings, timing characteristics, and compliance certifications.

Compliance and Certification Basis: Both parts carry Active product status, ROHS3 compliance, REACH Unaffected designation, and identical export control classifications (ECCN 5A991A, HTSUS 8542.39.0001). Selection between these parts is determined solely by channel count and channel configuration requirements, not by performance or regulatory differences.

Frequently Asked Questions (FAQ)

Q: Can IL 514E replace IL 516E in all applications?

A: No. The IL 514E provides only 3 channels versus the IL 516E's 4 channels. Substitution is valid only when the application design uses 3 or fewer isolated channels. If the circuit design requires all 4 channels of the IL 516E, the IL 514E cannot be used as a direct replacement.

Q: Are the electrical performance specifications identical between IL 516E and IL 514E?

A: Yes. Both parts share identical isolation voltage (2500Vrms), common mode transient immunity (30kV/µs), data rate (2Mbps), propagation delay (25ns), pulse width distortion (10ns), supply voltage range (3V ~ 5.5V), and operating temperature range (-40°C ~ 85°C).

Q: Do both parts use the same package?

A: Yes. Both IL 516E and IL 514E use the 16-SOIC (0.295", 7.50mm Width) surface mount package. PCB footprints are identical, and both parts are compatible with the same assembly processes.

Q: What is the difference in channel configuration between these parts?

A: The IL 516E has 4 channels with 2 inputs on Side 1 and 2 inputs on Side 2 (2/2 configuration). The IL 514E has 3 channels with 2 inputs on Side 1 and 1 input on Side 2 (2/1 configuration).

Q: Are both parts RoHS3 compliant?

A: Yes. Both IL 516E and IL 514E are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.

Q: What is the technology used in both isolators?

A: Both parts use Giant Magnetoresistive (GMR) technology as part of the IsoLoop® series from NVE Corp/Isolation Products.
