TS122S Equivalent & Substitute Parts

Part Overview

The TS122S is a telecom interface IC relay switch manufactured by IXYS Integrated Circuits Division, designed for surface mount applications in 8-SMD packaging. This component functions as a relay switch with two circuits and operates across an industrial temperature range of -40°C to 85°C with 800 mW power dissipation. The TS122S is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TS122S is determined by matching the following critical parameters:

• Function: Relay Switch
• Number of Circuits: 2
• Power Dissipation: 800 mW
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Package / Case: 8-SMD, Gull Wing
• Supplier Device Package: 8-SMD
• Moisture Sensitivity Level: 1 (Unlimited)

Both TS117S and TS117LS meet all specified electrical and mechanical parameters required for direct substitution. These parts are manufactured by the same supplier (IXYS Integrated Circuits Division) and maintain identical functional specifications, thermal characteristics, and physical packaging requirements.

Parameter Comparison

Engineering Selection Recommendations

Both TS117S and TS117LS are qualified substitutes for the obsolete TS122S. The primary distinction between these alternatives is product status and compliance certification:

TS117S and TS117LS are both active products with ROHS3 compliance, providing long-term availability and regulatory alignment for new designs and production continuity. Both parts maintain identical electrical performance, thermal operating range, and physical packaging specifications as the TS122S.

Selection between TS117S and TS117LS should be based on supply chain availability and packaging preference (both supplied in Tube packaging). The base product number TS117 is common to both variants, indicating they share the same core design and functional characteristics.

Frequently Asked Questions (FAQ)

Q: Can TS117S and TS117LS be used interchangeably with TS122S?

A: Yes. Both TS117S and TS117LS meet all specified electrical and mechanical parameters of the TS122S, including relay switch function, dual-circuit configuration, 800 mW power dissipation, -40°C to 85°C operating temperature range, and 8-SMD gull wing surface mount packaging.

Q: Why is the TS122S classified as obsolete?

A: The TS122S has been discontinued by the manufacturer. TS117S and TS117LS are the active production alternatives that provide equivalent functionality and performance.

Q: Are there any compliance differences between the substitute parts?

A: TS117S and TS117LS are both ROHS3 compliant and REACH unaffected, providing regulatory compliance for current manufacturing standards. The TS122S compliance status for RoHS was not specified in available documentation.

Q: What is the difference between TS117S and TS117LS?

A: Both parts share identical electrical specifications, thermal characteristics, and physical packaging. The designation difference reflects variant coding within the TS117 product family. Selection should be based on current inventory availability and supplier recommendations.

Q: Is the 8-SMD gull wing package compatible with existing PCB designs for TS122S?

A: Yes. Both substitute parts use the identical 8-SMD gull wing package specification, ensuring direct physical and electrical compatibility with existing printed circuit board layouts and assembly processes.
