XS170S Equivalent & Substitute Parts

Part Overview

The XS170S is a telecom interface IC relay switch manufactured by IXYS Integrated Circuits Division in an 8-SMD surface mount package. This component functions as a relay switch with 2 circuits, designed for telecommunications applications requiring signal switching and isolation. The XS170S is classified as obsolete, making identification of active equivalent parts essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XS170S is determined by the following critical parameters:

• Function: Relay Switch (2 circuits)
• Power Dissipation: 800 mW
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 8-SMD, Gull Wing
• Mounting Technology: Surface Mount
• Compliance: ROHS3 Compliant, REACH Unaffected

The substitute parts TS117S and TS117LS are parametric equivalents manufactured by the same supplier (IXYS Integrated Circuits Division). Both maintain identical electrical specifications, thermal operating range, power rating, circuit count, and physical packaging. The primary distinction between substitutes is product status and packaging format (Tube packaging for both active alternatives versus the original gull wing configuration).

Parameter Comparison

Engineering Selection Recommendations

Both TS117S and TS117LS serve as direct functional replacements for the obsolete XS170S. Selection between these active alternatives should be based on:

TS117S: Recommended for standard production applications requiring active component availability with established supply chain support. This part maintains full parametric equivalence and ROHS3 compliance.

TS117LS: Recommended where tube packaging format aligns with assembly line requirements. This variant provides identical electrical and thermal performance with alternative packaging configuration.

Both substitutes maintain compliance with ROHS3 and REACH requirements, ensuring regulatory alignment with current environmental and hazardous substance directives. The transition from the obsolete XS170S to either active substitute presents no electrical or thermal performance degradation.

Frequently Asked Questions (FAQ)

Q: Can TS117S and TS117LS be used interchangeably with XS170S?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, power dissipation, operating temperature range, circuit count, and 8-SMD gull wing packaging. The primary difference is packaging format (Tube) and active product status.

Q: What is the difference between TS117S and TS117LS?

A: Both parts are electrically and mechanically identical. The designation difference reflects packaging and supplier configuration. Selection should be based on assembly process requirements and packaging compatibility with existing equipment.

Q: Why is XS170S classified as obsolete?

A: The XS170S has reached end-of-life status. Active alternatives TS117S and TS117LS provide equivalent functionality and are recommended for new designs and ongoing production support.

Q: Are there any compliance concerns when substituting XS170S with TS117S or TS117LS?

A: No. All three parts maintain ROHS3 compliance and REACH unaffected status. Substitution presents no regulatory or environmental compliance issues.

Q: Does package format affect circuit board layout?

A: Both substitute parts maintain the 8-SMD gull wing package specification identical to XS170S. PCB footprints and assembly processes remain unchanged.
