TS120S Equivalent & Substitute Parts

Part Overview

The TS120S is a telecom interface IC relay switch manufactured by IXYS Integrated Circuits Division, designed for surface mount applications in 8-SMD gull wing packaging. This component functions as a relay switch with dual circuits and 800 mW power dissipation capability, operating across the industrial temperature range of -40°C to 85°C. The TS120S is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TS120S is determined by strict equivalence across the following parameters:

• Function: Relay Switch with dual circuits (2 circuits)
• Power dissipation: 800 mW
• Operating temperature range: -40°C to 85°C
• Mounting technology: Surface mount
• Physical package: 8-SMD, Gull Wing configuration
• Electrical interface: Telecom interface classification
• Compliance standards: ROHS3 Compliant, REACH Unaffected

The substitute parts TS117LS and TS117S meet all these criteria and are manufactured by the same supplier, IXYS Integrated Circuits Division. Both substitutes are classified as active products, providing design continuity for applications currently using the obsolete TS120S.

Parameter Comparison

Engineering Selection Recommendations

Both TS117LS and TS117S are direct functional equivalents to the TS120S and are suitable for replacement in applications requiring telecom interface relay switching. The primary distinction between the two substitutes is packaging format: TS117LS is supplied in tube packaging, while TS117S is also supplied in tube packaging. Both parts maintain active product status with IXYS Integrated Circuits Division, ensuring ongoing availability and technical support.

Selection between TS117LS and TS117S should be based on procurement requirements and inventory availability. Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current manufacturing standards. The identical electrical and thermal specifications ensure drop-in compatibility within existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can TS117LS and TS117S be used interchangeably with TS120S?

A: Yes. Both TS117LS and TS117S are parametric equivalents to TS120S across all critical specifications: dual-circuit relay switch function, 800 mW power rating, -40°C to 85°C operating temperature, 8-SMD gull wing package, and identical compliance certifications.

Q: What is the primary reason for substituting TS120S?

A: The TS120S is classified as obsolete. TS117LS and TS117S are active products from the same manufacturer, providing design continuity and assured long-term availability.

Q: Are there packaging differences between the substitute parts?

A: Both TS117LS and TS117S utilize identical 8-SMD gull wing surface mount packaging. The base product numbers differ (TS117 versus TS120), but the physical and electrical interfaces remain equivalent.

Q: Do the substitute parts meet current compliance standards?

A: Yes. Both TS117LS and TS117S are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: Is there a difference in moisture sensitivity between the main part and substitutes?

A: No. All three parts share identical MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
