IL 260-3 General Purpose Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 260-3 is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, part of the IsoLoop® IL260 series. This component provides galvanic isolation using Giant Magnetoresistive (GMR) technology with 2500Vrms isolation voltage across 5 unidirectional channels. The IL 260-3 is classified as an active product and is currently in production with 1035 units in stock.

Digital isolators are essential components in applications requiring electrical isolation between circuits operating at different voltage levels or ground potentials. Finding equivalent substitute parts becomes necessary when managing supply chain continuity, optimizing procurement costs, or addressing specific compliance requirements such as RoHS certification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL 260-3 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish the substitution criteria:

Electrical Parameters (Must Match Exactly):

• Number of Channels: 5
• Channel Configuration: Unidirectional (5 inputs / 0 outputs)
• Voltage - Isolation: 2500Vrms
• Common Mode Transient Immunity (Min): 30kV/µs
• Data Rate: 110Mbps
• Propagation Delay tpLH / tpHL (Max): 15ns / 15ns
• Pulse Width Distortion (Max): 3ns
• Rise / Fall Time (Typ): 1ns / 1ns
• Voltage - Supply: 3V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Technology & Series:

• Technology: GMR (Giant Magnetoresistive)
• Series: IsoLoop®, IL260

Parts meeting all these criteria are classified as direct substitutes. Variations in compliance certifications (RoHS status, REACH status) do not affect functional substitutability but may influence procurement decisions based on end-application requirements.

Parameter Comparison

Engineering Selection Recommendations

The IL 260-3E is a direct functional substitute for the IL 260-3. Both parts are manufactured by NVE Corp/Isolation Products and share identical electrical specifications, channel configuration, isolation voltage, data rate, timing characteristics, and package specifications.

The primary distinction between these parts is compliance certification status. The IL 260-3E carries ROHS3 compliance, while the IL 260-3 is RoHS non-compliant. Both parts maintain REACH Unaffected status.

Selection Criteria:

For applications subject to RoHS3 regulatory requirements or procurement policies mandating RoHS compliance, the IL 260-3E is the appropriate selection.

For applications without RoHS compliance requirements, either part is functionally equivalent. The IL 260-3E currently has higher inventory availability (1972 units versus 1035 units).

Both parts are active products in production, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can IL 260-3E replace IL 260-3 in existing designs?

A: Yes. The IL 260-3E is a direct functional substitute. All electrical parameters, channel configuration, isolation voltage, data rate, timing specifications, and package dimensions are identical. No circuit modifications are required.

Q: What is the difference between IL 260-3 and IL 260-3E?

A: The IL 260-3E is ROHS3 compliant, while the IL 260-3 is RoHS non-compliant. All other specifications are identical. The "E" designation indicates the RoHS3 compliant variant.

Q: Are both parts pin-compatible?

A: Yes. Both parts use the 16-SOIC (0.154", 3.90mm Width) package with identical pin assignments. PCB layouts and footprints are interchangeable.

Q: Which part should I select for new designs?

A: For new designs, the IL 260-3E is recommended due to ROHS3 compliance, which aligns with current regulatory standards and procurement policies. Both parts are active products with stable supply.

Q: Do these parts have the same operating temperature range?

A: Yes. Both IL 260-3 and IL 260-3E operate across -40°C to 85°C.

Q: Are there any differences in isolation voltage or data rate?

A: No. Both parts provide 2500Vrms isolation voltage and 110Mbps data rate with identical timing characteristics.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
