THS6042CDR Equivalent & Substitute Parts

Part Overview

The THS6042CDR is a 2/0 Driver DSL interface IC manufactured by Texas Instruments in an 8-SOIC surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The part operates across a 5V to 15V supply range and is rated for 0°C to 70°C operating temperatures. Due to its obsolete status, substitute parts with compatible electrical and mechanical specifications are required for procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the THS6042CDR are identified based on the following critical parameters that determine functional compatibility:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — mechanical and electrical interface compatibility
• Mounting Type: Surface Mount — PCB assembly process compatibility
• Voltage - Supply Range: 4V ~ 28V (single/dual ±2V ~ 14V) — operational envelope compatibility
• Number of Circuits: 2 — functional channel count
• Current Feedback Amplifier Architecture: Video amplifier topology with current feedback design

The substitute parts LT1253CS8, LT1253CS8#PBF, and LT1253CS8#TRPBF are Linear Technology / Analog Devices current feedback amplifiers that meet these core compatibility criteria. All three variants share identical electrical specifications and differ only in packaging format (Bulk, Tube, and Tape & Reel respectively).

Parameter Comparison

Engineering Selection Recommendations

LT1253CS8#PBF and LT1253CS8#TRPBF are the preferred substitutes for the obsolete THS6042CDR. Both variants are manufactured by Analog Devices Inc., carry Active product status, and maintain ROHS3 compliance with MSL 1 (Unlimited) ratings. These parts are electrically and mechanically identical, differing only in packaging format (Tube versus Tape & Reel). Selection between these two should be based on procurement and assembly process requirements.

LT1253CS8 (Linear Technology variant) is electrically compatible but carries RoHS non-compliant status, making it unsuitable for applications requiring regulatory compliance certification.

All three substitute options provide superior electrical performance characteristics compared to the original THS6042CDR, including extended voltage supply range (4V ~ 28V versus 5V ~ 15V), higher bandwidth (270 MHz), and faster slew rate (250V/µs).

Frequently Asked Questions (FAQ)

Q: Can LT1253CS8 variants be used as direct pin-for-pin replacements for THS6042CDR?

A: Yes. All substitute parts share identical 8-SOIC package geometry (0.154", 3.90mm Width) and pin configuration, enabling direct PCB substitution without layout modifications.

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

A: These are identical electrical components differentiated by packaging format only. LT1253CS8 is supplied in Bulk packaging, LT1253CS8#PBF in Tube, and LT1253CS8#TRPBF in Tape & Reel (TR). Selection depends on procurement volume and assembly automation requirements.

Q: Does the extended voltage supply range of LT1253 substitutes affect circuit design?

A: The LT1253 variants operate across 4V ~ 28V (single/dual ±2V ~ 14V), which encompasses the original THS6042CDR specification of 5V ~ 15V. Existing circuit designs require no modification for voltage compatibility.

Q: Are there RoHS compliance considerations for substitute selection?

A: Yes. LT1253CS8#PBF and LT1253CS8#TRPBF are ROHS3 compliant, matching the original THS6042CDR certification. The LT1253CS8 variant is RoHS non-compliant and should be avoided in applications requiring regulatory compliance.

Q: What is the moisture sensitivity level (MSL) for substitute parts?

A: LT1253CS8#PBF and LT1253CS8#TRPBF both carry MSL 1 (Unlimited), identical to the original THS6042CDR, indicating no moisture sensitivity restrictions for storage and handling.
