TS190S Equivalent & Substitute Parts

Part Overview

The TS190S is a telecom interface IC relay switch manufactured by IXYS Integrated Circuits Division, designed for telecommunications applications requiring relay switching functionality. This component features 2 circuits in an 8-SMD surface mount package with a power rating of 800 mW and an operating temperature range of -40°C to 85°C. The TS190S 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 TS190S is determined by the following critical parameters:

• Function: Relay Switch (2 circuits required)
• Power Rating: 800 mW
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 8-SMD, Gull Wing surface mount
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The TS117S and TS117LS are parametric equivalents to the TS190S. Both parts share identical electrical specifications, thermal operating range, power dissipation, circuit count, and package configuration. The primary distinction between these substitutes is product status and packaging format, with both TS117S and TS117LS classified as active products, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Both TS117S and TS117LS are direct substitutes for the obsolete TS190S. Selection between these two active alternatives should be based on packaging and procurement requirements:

TS117S: Recommended for applications where tube packaging is acceptable and standard procurement channels are utilized.

TS117LS: Recommended for applications where tube packaging is specified or preferred for handling and storage protocols.

Both substitutes maintain full compliance with ROHS3 and REACH regulations, ensuring compatibility with current environmental and regulatory standards. The transition from the obsolete TS190S to either active substitute presents no electrical or mechanical incompatibility, as all critical parameters remain identical.

Frequently Asked Questions (FAQ)

Q: Can TS117S or TS117LS be used as direct replacements for TS190S in existing designs?

A: Yes. Both TS117S and TS117LS are parametric equivalents with identical electrical specifications, power ratings, operating temperature ranges, circuit counts, and 8-SMD package configurations. No design modifications are required.

Q: What is the difference between TS117S and TS117LS?

A: The primary difference is packaging format. TS117S is supplied in tube packaging, while TS117LS is also supplied in tube packaging. Both parts are functionally and electrically identical and share the same base product number (TS117).

Q: Why is the TS190S classified as obsolete?

A: The TS190S has been discontinued by the manufacturer. The TS117S and TS117LS are the active product line replacements that maintain full parametric equivalence.

Q: Are there any compliance or certification differences between TS190S and its substitutes?

A: No. All three parts maintain identical ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited). Regulatory and environmental compliance requirements are fully satisfied by either substitute.

Q: What inventory considerations should be evaluated when transitioning from TS190S to TS117S or TS117LS?

A: Both TS117S and TS117LS are available in active inventory. TS117LS has 2478 units in stock, while TS117S has 2120 units in stock, providing adequate supply for procurement planning and design transitions.
