IL 610A-3 Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 610A-3 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 and single-channel unidirectional configuration. The IL 610A-3 is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The IL 610A-3E serves as the direct functional equivalent with active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution between IL 610A-3 and IL 610A-3E is based on strict equivalence of the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Isolation voltage: 2500Vrms (identical)
• Common Mode Transient Immunity: 15kV/µs (identical)
• Data rate: 10Mbps (identical)
• Supply voltage range: 3V ~ 5.5V (identical)
• Number of channels: 1 (identical)
• Channel configuration: Unidirectional, 1 input / 0 outputs (identical)

Mechanical Equivalence Criteria:

• Package type: 8-SOIC (0.154", 3.90mm Width) (identical)
• Mounting type: Surface Mount (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Substitution Basis: IL 610A-3E is the direct successor to IL 610A-3. Both parts share identical core isolation specifications, data rate performance, and physical packaging. The primary differences are product status (obsolete vs. active) and operating temperature range. IL 610A-3E is suitable for applications where IL 610A-3 was previously specified.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: IL 610A-3E is the appropriate selection for new product development. This part carries active product status from NVE Corp/Isolation Products and meets ROHS3 compliance requirements, aligning with current regulatory standards for electronic components.

For Existing Designs Using IL 610A-3: IL 610A-3E provides direct substitution with identical electrical performance and physical packaging. The operating temperature range of IL 610A-3E (-40°C ~ 85°C) is narrower than IL 610A-3 (-55°C ~ 125°C). Substitution is appropriate for applications operating within the -40°C ~ 85°C range. Applications requiring operation below -40°C or above 85°C require thermal performance verification against original specifications.

Compliance Considerations: IL 610A-3E meets ROHS3 compliance, whereas IL 610A-3 is non-compliant. For applications subject to RoHS regulations, IL 610A-3E is the required selection. Both parts maintain REACH Unaffected status.

Packaging and Inventory: IL 610A-3E is supplied in Tube packaging with 1406 units in stock. IL 610A-3 remains available with 790 units in stock but carries obsolete status. For production continuity, transition to IL 610A-3E is recommended.

Frequently Asked Questions (FAQ)

Q: Can IL 610A-3E directly replace IL 610A-3 in existing circuit designs?

A: Yes, IL 610A-3E provides direct electrical and mechanical substitution. Both parts share identical isolation voltage (2500Vrms), data rate (10Mbps), CMTI (15kV/µs), supply voltage range (3V ~ 5.5V), and 8-SOIC package configuration. No circuit modifications are required for pin-compatible substitution.

Q: What is the difference in operating temperature range between these parts?

A: IL 610A-3 operates from -55°C to 125°C, while IL 610A-3E operates from -40°C to 85°C. The IL 610A-3E range is narrower. For applications requiring operation below -40°C or above 85°C, the original IL 610A-3 specifications must be maintained, or alternative parts must be evaluated.

Q: Why is IL 610A-3 listed as obsolete?

A: IL 610A-3 is obsolete due to product lifecycle management by NVE Corp/Isolation Products. IL 610A-3E is the active equivalent and recommended for all new designs and production transitions.

Q: Are there packaging differences between IL 610A-3 and IL 610A-3E?

A: Both parts use identical 8-SOIC (0.154", 3.90mm Width) surface mount packaging. IL 610A-3E is supplied in Tube packaging, while IL 610A-3 packaging type is not specified in available data. The physical component dimensions and pin configuration are identical.

Q: What is the significance of ROHS3 compliance on IL 610A-3E?

A: IL 610A-3E meets ROHS3 (Restriction of Hazardous Substances Directive 3) compliance, restricting the use of specified hazardous materials. IL 610A-3 is non-compliant. For applications subject to RoHS regulations or customer requirements, IL 610A-3E is the compliant selection.

Q: Are the propagation delay specifications identical between these parts?

A: Yes, both parts specify identical maximum propagation delay: tpLH = 75ns and tpHL = 25ns. Timing-critical applications can substitute IL 610A-3E without timing performance degradation.

Q: What is the isolation voltage rating, and is it identical for both parts?

A: Both IL 610A-3 and IL 610A-3E provide 2500Vrms galvanic isolation with 15kV/µs Common Mode Transient Immunity. These specifications are identical and determine the maximum voltage differential that can be safely isolated between input and output sides.
