TS190PTR Telecom Interface IC - Equivalent & Substitute Parts

Part Overview

The TS190PTR 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 rating, operating across the -40°C to 85°C temperature range. The TS190PTR 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 TS190PTR is determined by the following critical parameters:

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

The TS117LSTR and TS117STR are parametric equivalents that satisfy all critical electrical and mechanical parameters. Both parts maintain identical functional specifications, thermal operating range, power dissipation, circuit count, and compliance certifications. The primary distinction between these substitutes is packaging format: TS117LSTR is supplied in Tape & Reel (TR) format, while TS117STR is also supplied in Tape & Reel (TR) format. Both represent active product status alternatives to the obsolete TS190PTR.

Parameter Comparison

Engineering Selection Recommendations

Both TS117LSTR and TS117STR are qualified substitutes for the obsolete TS190PTR. Selection between these two active alternatives should be based on procurement and supply chain requirements:

TS117LSTR provides 2,100 units in current inventory with Tape & Reel packaging, suitable for automated assembly processes requiring standard reel formats.

TS117STR provides 6,165 units in current inventory with Tape & Reel packaging, offering higher stock availability for volume production requirements.

Both parts maintain full compliance with ROHS3 and REACH regulations, ensuring regulatory alignment with current environmental standards. The transition from the obsolete TS190PTR to either active substitute presents no electrical or thermal performance degradation, as all critical parameters remain identical.

Frequently Asked Questions (FAQ)

Q: Can TS117LSTR or TS117STR be used as direct replacements for TS190PTR?

A: Yes. Both TS117LSTR and TS117STR are parametric equivalents meeting all electrical, thermal, and mechanical specifications of the TS190PTR. The 8-SMD, Gull Wing package configuration, dual-circuit relay switch function, 800 mW power rating, and -40°C to 85°C operating temperature range are identical across all three parts.

Q: What is the difference between TS117LSTR and TS117STR?

A: Both parts are functionally and electrically identical. The distinction lies in packaging format and inventory availability. TS117LSTR provides 2,100 units in stock, while TS117STR provides 6,165 units in stock. Both are supplied in Tape & Reel (TR) format for automated assembly.

Q: Are there any compliance or certification differences between these substitutes?

A: No. All three parts—TS190PTR, TS117LSTR, and TS117STR—carry identical ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: Why is the TS190PTR classified as obsolete?

A: The TS190PTR is no longer in active production. The TS117 series (TS117LSTR and TS117STR) represent the current active product line from IXYS Integrated Circuits Division for this functional category.

Q: Are there any PCB layout or footprint considerations when substituting these parts?

A: All three parts share the 8-SMD, Gull Wing package configuration. PCB footprints and layout requirements remain unchanged during substitution.
