TS190 Telecom Interface IC Equivalent & Substitute Parts

Part Overview

The TS190 is a telecom interface integrated circuit in 8-DIP packaging manufactured by IXYS Integrated Circuits Division. This component functions as a relay switch with two circuits, designed for telecom applications requiring signal switching and interface control. The TS190 is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations. Substitute parts must maintain identical electrical characteristics and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TS190 is determined by strict parametric matching across the following criteria:

• Identical relay switch function with two circuits
• Matching power dissipation of 800 mW
• Identical operating temperature range of -40°C to 85°C
• Identical 8-DIP package configuration (0.300", 7.62mm)
• Through-hole mounting compatibility
• ROHS3 compliance and MSL Level 1 rating
• Matching REACH and ECCN classifications

The TS117 and TS117L meet all substitution parameters and are classified as parametric equivalents. Both parts maintain active product status, ensuring ongoing availability and manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

Both TS117 and TS117L are direct substitutes for the obsolete TS190 based on complete parametric alignment and compliance certification matching.

The TS117L, manufactured by IXYS Integrated Circuits Division, maintains the original manufacturer lineage and is designated as a base product variant. This part carries 2112 units in current inventory.

The TS117, manufactured by Littelfuse, provides an alternative source from an established telecom interface component supplier. This part carries 1114 units in current inventory.

Both parts satisfy ROHS3 compliance requirements, REACH unaffected status, and EAR99 export classification. Selection between TS117 and TS117L may be determined by supply chain preferences, inventory availability, or existing qualification documentation within your organization.

Frequently Asked Questions (FAQ)

Q: Can TS117 and TS117L be used interchangeably with TS190?

A: Yes. Both TS117 and TS117L are parametric equivalents meeting all electrical and mechanical specifications of the TS190, including relay switch function, two-circuit configuration, 800 mW power dissipation, -40°C to 85°C operating range, and 8-DIP through-hole package format.

Q: What is the difference between TS117 and TS117L?

A: TS117L is a variant designation of the TS117 base product, both meeting identical parametric requirements. The primary difference is manufacturer: TS117L is supplied by IXYS Integrated Circuits Division, while TS117 is supplied by Littelfuse. Both maintain active product status and equivalent compliance certifications.

Q: Are there any packaging differences between these parts?

A: The TS190 is supplied in standard packaging, while TS117 is supplied in tube packaging. Both use identical 8-DIP (0.300", 7.62mm) component packages suitable for through-hole mounting. Packaging format does not affect electrical or mechanical compatibility.

Q: Do these parts require any circuit modifications for substitution?

A: No circuit modifications are required. The TS117 and TS117L maintain identical pinout, electrical characteristics, and functional behavior as the TS190, enabling direct socket replacement.

Q: What compliance certifications apply to substitute parts?

A: Both TS117 and TS117L carry ROHS3 compliance, MSL Level 1 (unlimited moisture sensitivity), REACH unaffected status, and EAR99 export classification, matching the TS190 certifications exactly.
