IL 260B Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 260B 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 5 channels. The IL 260B is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure direct replacement capability in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IL 260B are identified based on strict parametric equivalence. The following electrical and mechanical parameters determine substitution eligibility:

Critical Matching Parameters:

• Number of Channels: 5
• Voltage - Isolation: 2500Vrms
• Data Rate: 110Mbps
• Common Mode Transient Immunity: 30kV/µs
• Voltage - Supply Range: 3V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Technology: GMR (Giant Magnetoresistive)
• Series: IsoLoop®

The IL 260 and IL 260E are parametric equivalents of the IL 260B. Both parts maintain identical electrical specifications and mechanical form factor, enabling direct substitution in circuit designs. The primary distinction between these parts is product status and compliance certification, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

IL 260 (Active Status, RoHS Non-Compliant): The IL 260 is an active product offering identical electrical and mechanical specifications to the obsolete IL 260B. This part maintains the same GMR technology, isolation voltage, data rate, and package configuration. Selection of IL 260 is appropriate for applications where RoHS compliance is not a regulatory requirement and where existing design validation against the IL 260B specification is applicable.

IL 260E (Active Status, ROHS3 Compliant): The IL 260E is an active product with ROHS3 compliance certification, providing the same electrical performance and mechanical compatibility as the IL 260B. This part is the preferred substitute for new designs or applications subject to RoHS3 regulatory requirements. The IL 260E maintains all critical electrical parameters and package specifications, enabling direct substitution with the added benefit of environmental compliance certification.

Compliance Considerations: The IL 260B and IL 260 are both RoHS non-compliant. The IL 260E provides ROHS3 compliance, making it the appropriate choice for applications in regulated markets or where environmental compliance is mandated. All three parts share identical REACH status (REACH Unaffected) and ECCN classification (5A991A).

Frequently Asked Questions (FAQ)

Q: Can IL 260 or IL 260E be used as direct replacements for IL 260B in existing designs?

A: Yes. Both IL 260 and IL 260E are parametric equivalents with identical electrical specifications and 16-SOIC package configuration. Direct substitution is supported without circuit modification, provided the application does not require specific compliance certifications beyond those of the IL 260B.

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

A: The IL 260 and IL 260E are electrically and mechanically identical. The primary difference is RoHS compliance status: IL 260 is RoHS non-compliant, while IL 260E is ROHS3 compliant. Both parts are active products with equivalent performance characteristics.

Q: Why is IL 260B classified as obsolete?

A: The IL 260B is obsolete, meaning it is no longer in active production. However, inventory remains available. For new designs or long-term procurement, IL 260 or IL 260E should be selected to ensure ongoing supply chain support.

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

A: No. All three parts (IL 260B, IL 260, IL 260E) maintain identical isolation voltage (2500Vrms), data rate (110Mbps), and common mode transient immunity (30kV/µs). These critical parameters are equivalent across all variants.

Q: What packaging options are available?

A: IL 260B is supplied with unspecified packaging. IL 260 and IL 260E are supplied in Tube packaging. All three parts use the same 16-SOIC (0.295", 7.50mm Width) case configuration for surface mount assembly.

Q: Which part should be selected for new designs?

A: IL 260E is recommended for new designs due to its active product status and ROHS3 compliance certification. This ensures long-term availability and regulatory compliance in markets with environmental requirements.

Q: Are there any temperature or supply voltage differences?

A: No. All three parts operate across the identical temperature range (-40°C ~ 85°C) and supply voltage range (3V ~ 5.5V). Operating conditions are fully equivalent.
