TS393CS Equivalent & Substitute Parts Reference

Part Overview

The TS393CS is a dual voltage comparator manufactured by Taiwan Semiconductor Corporation, classified as a general-purpose linear integrated circuit. This device operates across a wide supply voltage range of 2V to 36V (single supply) or ±1V to ±18V (dual supply), making it suitable for diverse analog signal processing applications. The TS393CS is currently in active product status with 2151 units available in inventory. Substitute parts are necessary when addressing supply chain constraints, specific temperature range requirements, or when alternative manufacturers' components are preferred for design standardization or cost optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TS393CS is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts.

Functional Equivalence: Substitute parts must be dual-element general-purpose comparators with compatible output types (CMOS, DTL, ECL, MOS, TTL).

Supply Voltage Range: The substitute must operate within the application's required supply voltage window. The TS393CS supports 2V to 36V single supply or ±1V to ±18V dual supply. Substitute parts with narrower voltage ranges (such as MAX922 variants at 2.5V to 11V single supply) are acceptable only when the application operates within the substitute's specified range.

Input Offset Voltage: The TS393CS specifies 5mV maximum input offset at 30V. Substitute parts with higher input offset specifications (such as 10mV) may be used when the application's accuracy requirements permit.

Operating Temperature Range: The TS393CS operates from 0°C to 70°C. Substitutes with extended temperature ranges (such as -40°C to 85°C) are backward-compatible; substitutes with narrower ranges are not acceptable.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and REACH unaffected status to meet regulatory requirements.

Engineering Selection Recommendations

MAX922CSA+ (Analog Devices Inc./Maxim Integrated)

The MAX922CSA+ is an active substitute for applications operating within the 2.5V to 11V single supply range or ±1.25V to ±5.5V dual supply range. This part maintains identical operating temperature specifications (0°C to 70°C) and package format as the TS393CS. The MAX922CSA+ exhibits higher output current capability (50mA typical) compared to the TS393CS (16mA typical), making it suitable for applications requiring increased drive capability. Input offset voltage is specified at 10mV, which is acceptable for applications where the TS393CS's 5mV specification is not a critical requirement. The MAX922CSA+ is supplied in tube packaging and maintains ROHS3 compliance and REACH unaffected status. This part is recommended for designs where supply voltage does not exceed 11V single supply.

MAX922ESA+ (Analog Devices Inc./Maxim Integrated)

The MAX922ESA+ provides extended operating temperature range (-40°C to 85°C) compared to the TS393CS (0°C to 70°C), making it suitable for industrial and automotive temperature environments. Supply voltage specifications are identical to the MAX922CSA+ (2.5V to 11V single supply or ±1.25V to ±5.5V dual supply). The MAX922ESA+ maintains the same output current capability (50mA typical) and input offset voltage specification (10mV). This part is supplied in tube packaging and maintains ROHS3 compliance and REACH unaffected status. The MAX922ESA+ is recommended for applications requiring extended temperature operation within the specified voltage range.

SC2903VDR2G (onsemi)

The SC2903VDR2G is an obsolete product with supply voltage specifications matching the TS393CS (2V to 36V). This part maintains the same 8-SOIC package format and output type compatibility (CMOS, DTL, ECL, MOS, TTL). However, the SC2903VDR2G is classified as obsolete and carries AEC-Q100 automotive qualification. Critical parameters including input offset voltage, input bias current, quiescent current, and operating temperature range are not specified in available documentation. The SC2903VDR2G is not recommended for new designs due to obsolete status and incomplete parameter documentation. This part may only be considered for legacy system maintenance where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can the MAX922CSA+ replace the TS393CS in all applications?

A: The MAX922CSA+ is a suitable substitute only for applications where the supply voltage does not exceed 11V single supply or ±5.5V dual supply. The TS393CS supports up to 36V single supply or ±18V dual supply. If your application requires higher supply voltages, the MAX922CSA+ is not compatible. Additionally, the MAX922CSA+ specifies 10mV input offset voltage compared to the TS393CS's 5mV specification; verify that your application's accuracy requirements permit this higher offset.

Q: What is the advantage of using MAX922ESA+ over MAX922CSA+?

A: The MAX922ESA+ extends the operating temperature range to -40°C to 85°C, compared to the MAX922CSA+ and TS393CS at 0°C to 70°C. If your application requires operation at temperatures below 0°C or above 70°C, the MAX922ESA+ is necessary. All other electrical specifications remain identical between these two parts.

Q: Why is the SC2903VDR2G listed as a substitute if it is obsolete?

A: The SC2903VDR2G is included in the substitute list based on the provided input data; however, its obsolete status makes it unsuitable for new designs. This part should only be considered for legacy system maintenance or repair applications where existing inventory is available. For new designs, select either the MAX922CSA+ (for standard temperature range) or MAX922ESA+ (for extended temperature range).

Q: Are all substitute parts pin-compatible with the TS393CS?

A: Yes. All substitute parts listed (MAX922CSA+, MAX922ESA+, and SC2903VDR2G) use the 8-SOIC package format with identical pin spacing (0.154", 3.90mm width). Pin-to-pin compatibility is maintained across all listed substitutes.

Q: What packaging options are available for substitute parts?

A: The MAX922CSA+ and MAX922ESA+ are supplied in tube packaging. The SC2903VDR2G packaging specification is not provided in available documentation. All parts are surface mount components suitable for automated assembly processes.

Q: How do I determine which substitute is appropriate for my application?

A: First, verify your application's supply voltage requirements. If voltage exceeds 11V single supply or ±5.5V dual supply, neither MAX922 variant is suitable; the TS393CS or SC2903VDR2G (if available) must be used. Second, determine your operating temperature range. If operation below 0°C or above 70°C is required, select the MAX922ESA+. For standard temperature range (0°C to 70°C) applications within the voltage limits, either MAX922CSA+ or MAX922ESA+ is acceptable. Third, verify that input offset voltage specifications meet your accuracy requirements; the MAX922 variants specify 10mV compared to the TS393CS's 5mV.
