TS613IDW Equivalent & Substitute Parts

Part Overview

The TS613IDW is a voltage feedback amplifier integrated circuit manufactured by STMicroelectronics, featuring two circuits in an 8-SOP package. This component is classified as obsolete, indicating discontinuation from active production. The TS613IDW operates across a supply voltage range of 5V to 12V with a slew rate of 40V/µs and gain bandwidth product of 130 MHz, making it suitable for analog signal conditioning applications requiring dual-channel amplification.

Due to its obsolete status, identifying equivalent and substitute parts is necessary for design continuity, system maintenance, and procurement of replacement inventory. Substitute components must maintain compatibility with the original electrical specifications and physical packaging requirements.

Substitute Part Grouping Explanation

Substitution of the TS613IDW requires evaluation based on the following critical parameters:

Package Compatibility: The original component uses an 8-SOIC (0.154", 3.90mm Width) package. Substitute parts must use either the same 8-SOIC package or the 8-PowerSOIC variant, both maintaining identical physical dimensions and pin pitch for direct board-level replacement.

Supply Voltage Range: The TS613IDW operates within 5V to 12V. Substitute components must support this voltage range or a range that encompasses it. Parts with supply ranges of 3.3V to 8V or 5V to 15V are evaluated for compatibility based on application requirements.

Operating Temperature Range: The original part specifies -40°C to 85°C operation. Substitute parts meeting or exceeding this temperature range maintain thermal compatibility.

Surface Mount Technology: All substitute candidates utilize surface mount packaging, ensuring compatibility with modern PCB assembly processes.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are maintained across all substitute options, ensuring environmental and regulatory alignment.

The substitute parts listed are classified as Interface drivers rather than voltage feedback amplifiers. This functional difference indicates that direct electrical equivalence cannot be guaranteed based on the provided parameters. Selection of substitutes requires verification of circuit-level compatibility beyond the scope of this parameter comparison.

Engineering Selection Recommendations

Primary Substitutes (Active Status):

The THS6052ID and THS6052IDDA from Texas Instruments represent the most viable substitutes based on active product status and full operating temperature range compatibility (-40°C to 85°C). Both components maintain the 8-SOIC package format and support the 5V to 15V supply range, which encompasses the original TS613IDW specification of 5V to 12V. THS6052ID is available in standard tube packaging with 6511 units in stock, while THS6052IDDA provides the PowerSOIC variant with 829 units available.

The THS6042ID and THS6042IDDA from Texas Instruments offer alternative options with active or last-time-buy status. THS6042ID maintains full temperature range operation and standard 8-SOIC packaging with 1244 units in inventory. THS6042IDDA provides the PowerSOIC package variant with 1360 units available.

Secondary Substitutes (Limited Availability):

The AD8018ARZ series from Analog Devices Inc. provides active alternatives with full temperature range support (-40°C to 85°C). However, the maximum supply voltage of 8V does not fully encompass the original 12V maximum specification. AD8018ARZ is available in tube packaging (5623 units), AD8018ARZ-REEL in standard reel format (2300 units), and AD8018ARZ-REEL7 in tape and reel format (1378 units).

Compliance Considerations:

All substitute options maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component. Moisture sensitivity levels are improved across all substitutes (MSL 1 versus MSL 3 for the original), reducing handling and storage constraints.

Packaging Variants:

Selection between standard 8-SOIC and 8-PowerSOIC packages depends on thermal dissipation requirements. The PowerSOIC variant provides enhanced thermal performance through an exposed pad design, suitable for applications requiring higher output current delivery.

Frequently Asked Questions (FAQ)

Q: Can the AD8018ARZ series directly replace the TS613IDW in all applications?

A: The AD8018ARZ series supports a maximum supply voltage of 8V, which is below the TS613IDW maximum of 12V. Direct substitution is limited to applications operating within the 5V to 8V range. Applications requiring operation above 8V require alternative substitutes from the THS6042 or THS6052 series.

Q: What is the difference between 8-SOIC and 8-PowerSOIC packages?

A: Both packages maintain identical external dimensions (0.154", 3.90mm width) and pin pitch, allowing physical interchangeability on the PCB. The 8-PowerSOIC variant includes an exposed thermal pad on the bottom surface, providing improved heat dissipation for applications with higher power dissipation requirements. Pin-to-pin compatibility is maintained between variants.

Q: Are the THS6042 and THS6052 series functionally equivalent?

A: Both series are classified as DSL drivers with 2/0 driver/receiver configuration and identical package options. The provided parameters do not include performance differentiators between these series. Application-specific requirements and detailed datasheet comparison are necessary to determine functional equivalence for specific circuit implementations.

Q: Why is the TS613IDW classified as obsolete?

A: The TS613IDW has been discontinued from active production by STMicroelectronics. Obsolete status indicates the component is no longer manufactured and existing inventory represents the final available supply. Substitute components ensure design continuity and system maintenance capability.

Q: What is the significance of MSL (Moisture Sensitivity Level) differences?

A: The TS613IDW carries MSL 3 (168 hours), requiring controlled storage and handling conditions to prevent moisture absorption. All substitute options carry MSL 1 (unlimited), eliminating moisture sensitivity constraints and reducing storage and handling complexity during procurement and assembly operations.

Q: Can I use THS6042IDG4 for new designs?

A: THS6042IDG4 is listed as discontinued at DiGi Electronics, indicating limited availability through standard distribution channels. While 1065 units are currently in stock, this component is not recommended for new designs requiring long-term supply assurance. Active alternatives such as THS6052ID or THS6052IDDA are preferred for new development.

Q: What supply voltage range should I select for my application?

A: If your application operates within 5V to 8V, the AD8018ARZ series is suitable. For applications requiring operation up to 12V or higher, select from the THS6042 or THS6052 series, which support 5V to 15V operation. Verify that your specific application voltage requirements fall within the selected substitute's rated supply range.

Q: Are all substitute parts available in both tube and reel packaging?

A: Packaging availability varies by part number. THS6052ID and THS6042ID are available in tube packaging. THS6052IDDA and THS6042IDDA are available in tube packaging with PowerSOIC packages. AD8018ARZ variants are available in tube, standard reel, and tape & reel formats. Verify packaging availability with your supplier for procurement requirements.
