All substitute parts listed maintain identical electrical performance specifications and mechanical compatibility with the IL 260-3B, ensuring direct functional replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

IL 260-3B (Obsolete Status): The IL 260-3B is classified as Obsolete and should not be selected for new designs or long-term production commitments. Current inventory of 752 pieces is available but represents a finite supply.

IL 260-3 (Active Status, RoHS Non-Compliant): The IL 260-3 is an Active product with identical electrical and mechanical specifications to the IL 260-3B. This part is suitable for direct substitution in existing designs and applications where RoHS non-compliance is acceptable. Inventory availability is 1035 pieces. This part maintains the same regulatory status (RoHS non-compliant, REACH Unaffected) as the obsolete IL 260-3B.

IL 260-3E (Active Status, ROHS3 Compliant): The IL 260-3E is an Active product with identical electrical and mechanical specifications to the IL 260-3B and IL 260-3. This part is suitable for direct substitution and is the preferred choice for applications requiring RoHS3 compliance. Inventory availability is 1972 pieces, the highest among all three variants. The IL 260-3E meets current regulatory requirements for restricted substances.

Selection Logic:

• For applications with no RoHS compliance requirement: IL 260-3 or IL 260-3E are equivalent substitutes
• For applications requiring RoHS3 compliance: IL 260-3E is the appropriate selection
• For obsolete design support: IL 260-3 provides direct functional replacement
• All three parts are electrically and mechanically interchangeable within the specified parameters

Frequently Asked Questions (FAQ)

Q: Can IL 260-3 or IL 260-3E be used as direct replacements for IL 260-3B?

A: Yes. IL 260-3 and IL 260-3E are parametric equivalents to IL 260-3B. All three parts share identical electrical specifications (2500Vrms isolation, 5 channels, 110Mbps data rate, 30kV/µs CMTI, 15ns propagation delay) and mechanical packaging (16-SOIC surface mount). They are functionally interchangeable in circuit designs.

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

A: The primary difference is regulatory compliance. IL 260-3 is RoHS non-compliant, while IL 260-3E is ROHS3 compliant. Both parts have identical electrical performance and package specifications. Selection between these two depends on regulatory requirements for the end application.

Q: Why is IL 260-3B classified as Obsolete?

A: IL 260-3B is listed as Obsolete by the manufacturer. IL 260-3 and IL 260-3E are the Active product variants within the IL260 series. For new designs and ongoing production, Active variants should be prioritized.

Q: Are there any differences in packaging between these parts?

A: IL 260-3B packaging is not specified in the available data. IL 260-3 and IL 260-3E are supplied in Tube packaging. All three parts use the same 16-SOIC (0.154", 3.90mm Width) package type for the component itself.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts (IL 260-3B, IL 260-3, and IL 260-3E) have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: Can these parts be used interchangeably in high-speed digital isolation applications?

A: Yes. All three parts meet the same electrical specifications for high-speed isolation: 110Mbps data rate, 15ns maximum propagation delay, 3ns maximum pulse width distortion, and 30kV/µs common mode transient immunity. They are suitable for identical application requirements.

Q: Which part should be selected for new production designs?

A: IL 260-3E is the recommended selection for new production designs. It is Active, offers the highest inventory availability (1972 pieces), and meets ROHS3 compliance requirements. IL 260-3 is an alternative if RoHS non-compliance is acceptable for the application.
