XS170 Equivalent & Substitute Parts

Part Overview

The XS170 is a telecom interface IC relay switch in 8-DIP packaging manufactured by IXYS Integrated Circuits Division. This component functions as a relay switch with two circuits, designed for telecommunications applications with 800 mW power dissipation and an operating temperature range of -40°C to 85°C. The XS170 is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the XS170 is determined by strict equivalence across the following parameters:

• Package Type: 8-DIP (0.300", 7.62mm) form factor
• Function: Relay switch with 2 circuits
• Power Dissipation: 800 mW
• Operating Temperature Range: -40°C to 85°C
• Mounting Method: Through Hole
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Two substitute parts meet these criteria: TS117 (Littelfuse) and TS117L (IXYS Integrated Circuits Division). Both parts maintain identical electrical and mechanical specifications to the XS170, ensuring direct functional compatibility in existing designs.

Parameter Comparison

Engineering Selection Recommendations

TS117 (Littelfuse) is the primary substitute for the obsolete XS170. This part is currently in active production status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment for new designs and production runs. TS117 is supplied in tube packaging.

TS117L (IXYS Integrated Circuits Division) is a parametric equivalent manufactured by the original XS170 supplier. This part maintains active product status with ROHS3 compliance and is available in tube packaging. TS117L serves as an alternative when supplier continuity with IXYS is preferred or when existing supply chain relationships favor this manufacturer.

Both substitutes are electrically and mechanically identical to the XS170 across all specified parameters. Selection between TS117 and TS117L should be based on procurement strategy, supplier preference, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can TS117 or TS117L be used as direct replacements for XS170 in existing designs?

A: Yes. Both TS117 and TS117L are direct functional equivalents. They share identical package type (8-DIP), circuit count (2), power rating (800 mW), operating temperature range (-40°C to 85°C), and mounting method (Through Hole). No circuit modifications are required.

Q: What is the difference between TS117 and TS117L?

A: TS117 is manufactured by Littelfuse, while TS117L is manufactured by IXYS Integrated Circuits Division. Both parts are parametrically identical and interchangeable. TS117L is designated as a base product variant of TS117.

Q: Why is the XS170 listed as obsolete?

A: The XS170 has been discontinued by IXYS Integrated Circuits Division. TS117 and TS117L represent the current active alternatives for this function.

Q: Are TS117 and TS117L RoHS compliant?

A: Yes. Both TS117 and TS117L are ROHS3 compliant. The XS170 RoHS status was not specified in available documentation.

Q: What packaging options are available for the substitute parts?

A: Both TS117 and TS117L are supplied in tube packaging. The XS170 packaging format was not specified.

Q: Are there any environmental or regulatory differences between these parts?

A: All three parts (XS170, TS117, TS117L) share identical REACH status (REACH Unaffected) and ECCN classification (EAR99). TS117 and TS117L carry ROHS3 compliance certification.
