TS190PL Equivalent & Substitute Parts

Part Overview

The TS190PL is a telecom interface relay switch IC manufactured by IXYS Integrated Circuits Division in an 8-Flatpack surface mount package. This component functions as a relay switch with dual circuits, rated at 800 mW power dissipation and operating across the temperature range of -40°C to 85°C. The TS190PL is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the TS190PL is determined by equivalence across the following critical parameters:

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

The substitute parts TS117LS and TS117S maintain identical electrical and thermal specifications while offering the advantage of active product status. Both substitutes are packaged in 8-SMD configuration with gull wing leads, ensuring mechanical and electrical compatibility with TS190PL footprints.

Parameter Comparison

Engineering Selection Recommendations

Both TS117LS and TS117S are direct functional equivalents to the obsolete TS190PL. Selection between these two active alternatives is based on packaging preference and inventory availability:

TS117LS is supplied in tube packaging and maintains 2478 units in current inventory stock.

TS117S is supplied in tube packaging and maintains 2120 units in current inventory stock.

Both parts satisfy ROHS3 compliance and REACH regulatory requirements. The transition from TS190PL to either TS117LS or TS117S requires no circuit redesign, as electrical performance, thermal characteristics, and physical footprint remain equivalent across all three part numbers.

Frequently Asked Questions (FAQ)

Q: Can TS117LS or TS117S be used as direct replacements for TS190PL in existing designs?

A: Yes. Both substitute parts maintain identical electrical specifications (800 mW power, dual relay switch function, -40°C to 85°C operating range) and physical package configuration (8-SMD, Gull Wing). No circuit modifications are required.

Q: What is the primary difference between TS117LS and TS117S?

A: Both parts are functionally and electrically identical. The designation difference reflects internal IXYS product line organization. Selection may be based on inventory availability or supplier preference.

Q: Why is the TS190PL classified as obsolete?

A: The TS190PL has been superseded by the TS117 series (TS117LS and TS117S), which are maintained as active products by IXYS Integrated Circuits Division.

Q: Are there any compliance or certification differences between TS190PL and its substitutes?

A: No. All three parts carry identical ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity ratings.

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

A: Both TS117LS and TS117S are supplied in tube packaging, consistent with standard surface mount component distribution for 8-SMD devices.
