TS190PLTR Telecom Interface IC - Equivalent & Substitute Parts

Part Overview

The TS190PLTR is a telecom interface relay switch IC manufactured by IXYS Integrated Circuits Division, designed for surface mount applications in 8-Flatpack packaging. This component functions as a relay switch with dual circuits and 800 mW power dissipation capability, operating across the -40°C to 85°C temperature range. The TS190PLTR 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 of the TS190PLTR is determined by the following critical parameters that must remain constant across equivalent parts:

• Function: Relay Switch
• Number of Circuits: 2
• Power Dissipation: 800 mW
• Operating Temperature Range: -40°C to 85°C
• Mounting Type: Surface Mount
• Package Configuration: 8-SMD, Gull Wing
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The TS117LSTR and TS117STR meet all these electrical and mechanical parameters. Both parts are manufactured by IXYS Integrated Circuits Division and maintain identical functional specifications. The primary distinction between these substitutes and the original TS190PLTR lies in packaging format (8-SMD versus 8-Flatpack) and product status (Active versus Obsolete). Both substitute parts are currently in active production status with substantial inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both TS117LSTR and TS117STR are qualified substitutes for the obsolete TS190PLTR based on electrical and mechanical parameter equivalence. Selection between the two active alternatives should be based on procurement availability and supply chain requirements:

TS117LSTR maintains 2100 units in current inventory stock.

TS117STR maintains 6165 units in current inventory stock, providing greater supply availability.

Both parts carry identical ROHS3 compliance certification and REACH unaffected status, meeting regulatory requirements equivalent to the original TS190PLTR. The transition from 8-Flatpack to 8-SMD packaging format does not affect functional performance, as both configurations maintain the same gull wing lead geometry and surface mount mounting type.

Frequently Asked Questions (FAQ)

Q: Can TS117LSTR and TS117STR be used interchangeably with TS190PLTR?

A: Yes. Both substitute parts maintain identical electrical specifications (2 circuits, 800 mW power dissipation, -40°C to 85°C operating range) and mechanical compatibility (8-SMD gull wing surface mount configuration). The primary difference is product status: TS190PLTR is obsolete while TS117LSTR and TS117STR are active production parts.

Q: What is the difference between TS117LSTR and TS117STR?

A: Both parts are functionally and electrically identical. The distinction lies in packaging format designation and inventory availability. TS117STR has higher stock levels (6165 units versus 2100 units for TS117LSTR).

Q: Are there any compliance or certification differences between the original and substitute parts?

A: No. All three parts carry identical ROHS3 compliance certification and REACH unaffected status. Moisture sensitivity level remains constant at MSL 1 (Unlimited) across all variants.

Q: Does the change from 8-Flatpack to 8-SMD packaging affect circuit board layout?

A: Both packaging formats maintain 8-SMD gull wing lead geometry and surface mount mounting type. Pin configuration and footprint compatibility remain consistent, allowing direct substitution in existing PCB designs.

Q: Why is TS190PLTR classified as obsolete?

A: The TS190PLTR has been discontinued by the manufacturer. TS117LSTR and TS117STR represent the active production equivalents that maintain all functional and electrical specifications required for relay switch applications in telecom interface circuits.
