THS6042CD Equivalent & Substitute Parts

Part Overview

The THS6042CD is a 2/0 Driver DSL interface IC manufactured by Texas Instruments in 8-SOIC surface mount packaging. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates across a 5V to 15V supply voltage range and is rated for 0°C to 70°C operating temperature. Identifying compatible alternatives ensures design continuity and supply chain flexibility for applications requiring DSL driver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the THS6042CD are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — physical and electrical interface compatibility
• Mounting Type: Surface Mount — PCB assembly process compatibility
• Voltage - Supply Range: 5V ~ 15V operational envelope
• Operating Temperature: 0°C ~ 70°C thermal operating range
• Number of Circuits: 2 channels for dual-channel driver functionality

The substitute parts listed (LT1253CS8, LT1253CS8#PBF, LT1253CS8#TRPBF) share identical package specifications, mounting technology, and electrical operating parameters. These parts are manufactured by Linear Technology and Analog Devices Inc., both established suppliers of interface and amplifier components. All substitutes maintain the 8-SOIC package form factor and support the required voltage and temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

LT1253CS8#PBF and LT1253CS8#TRPBF are the preferred substitute options. Both parts are manufactured by Analog Devices Inc., carry Active product status, and maintain full ROHS3 compliance and REACH Unaffected certification. These variants differ only in packaging format (Tube vs. Tape & Reel), allowing selection based on procurement and assembly requirements. Both provide superior supply availability compared to the obsolete THS6042CD.

LT1253CS8 (Linear Technology) is an alternative substitute with Active product status but carries RoHS non-compliant and REACH Affected designations. This variant may present regulatory constraints depending on application and regional requirements.

All three substitute parts operate within the THS6042CD voltage supply range (5V ~ 15V falls within the 4V ~ 28V single supply envelope) and maintain identical 8-SOIC package specifications and surface mount compatibility.

Frequently Asked Questions (FAQ)

Q: Can LT1253CS8 variants directly replace THS6042CD in existing designs?

A: Yes, from a mechanical and electrical standpoint. All substitute parts share the 8-SOIC package form factor, surface mount technology, and operate within the required 5V to 15V supply voltage range. Pin-level compatibility must be verified against specific application schematics.

Q: What is the difference between LT1253CS8#PBF and LT1253CS8#TRPBF?

A: The primary difference is packaging format. LT1253CS8#PBF is supplied in Tube packaging, while LT1253CS8#TRPBF is supplied in Tape & Reel format. Both are electrically and functionally identical. Selection depends on assembly process requirements and procurement volume.

Q: Why is LT1253CS8 (Linear Technology) marked as RoHS non-compliant?

A: This variant predates or does not meet current RoHS3 compliance standards. If your application requires RoHS3 certification, select LT1253CS8#PBF or LT1253CS8#TRPBF from Analog Devices Inc. instead.

Q: Are there supply chain advantages to using substitute parts?

A: Yes. The THS6042CD is obsolete with limited remaining inventory. All three substitute parts carry Active product status with significantly higher stock availability, ensuring reliable procurement for ongoing production and design iterations.

Q: What compliance certifications should I verify before selection?

A: Confirm RoHS and REACH compliance requirements for your application. LT1253CS8#PBF and LT1253CS8#TRPBF both maintain ROHS3 Compliant and REACH Unaffected status, matching the original THS6042CD certifications.
