TS118S Equivalent & Substitute Parts

Part Overview

The TS118S is a telecom interface integrated circuit manufactured by IXYS Integrated Circuits Division, designed for relay switching applications in telecommunications equipment. This component is classified as obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TS118S is determined by strict alignment across the following critical parameters:

• Function: Relay Switch
• Number of Circuits: 2
• Power Dissipation: 800 mW
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 8-SMD, Gull Wing
• Supplier Device Package: 8-SMD
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute parts TS117LS and TS117S meet all specified electrical and mechanical parameters. Both alternatives are manufactured by IXYS Integrated Circuits Division and maintain identical functional specifications, thermal operating range, power characteristics, and compliance certifications as the TS118S. The primary distinction between substitutes is packaging format (Tube) and active product status, which ensures ongoing availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

Both TS117LS and TS117S are qualified substitutes for the obsolete TS118S based on parametric equivalence and compliance alignment. Selection between the two active alternatives should be based on packaging requirements and supply chain logistics:

TS117LS is supplied in Tube packaging format with 2478 units in current inventory.

TS117S is supplied in Tube packaging format with 2120 units in current inventory.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory conformance for new designs and production applications. The transition from TS118S to either substitute part does not introduce compliance risk or require design modification beyond packaging accommodation.

Frequently Asked Questions (FAQ)

Q: Can TS117LS and TS117S be used interchangeably with TS118S?

A: Yes. Both TS117LS and TS117S are parametric equivalents to TS118S. All critical electrical parameters, thermal operating range, power dissipation, circuit count, package type, and compliance certifications are identical.

Q: What is the primary reason for substituting TS118S?

A: TS118S is classified as obsolete. TS117LS and TS117S are active products with confirmed inventory availability, ensuring reliable supply for production and field service applications.

Q: Are there packaging differences between the substitute parts?

A: TS118S was supplied without specified packaging format. Both TS117LS and TS117S are supplied in Tube packaging. PCB layout and assembly processes remain unchanged due to identical 8-SMD, Gull Wing package specifications.

Q: Do the substitute parts require design changes?

A: No design changes are required. The 8-SMD, Gull Wing package footprint, pin configuration, and electrical interface are identical across all three parts.

Q: Are compliance certifications maintained with substitution?

A: Yes. Both TS117LS and TS117S maintain ROHS3 compliance and REACH unaffected status, identical to TS118S specifications.
