Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC352IPWG4 is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 8-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width) to ensure PCB layout compatibility without redesign.

Functional Equivalence: The substitute must provide dual comparator functionality with differential input configuration and matching output type characteristics (CMOS, Open-Drain).

Electrical Operating Range: The substitute supply voltage range must encompass or exceed the TLC352IPWG4 operating specifications (1.4V ~ 16V single supply, ±0.7V ~ 8V dual supply).

Output Drive Capability: Current output specifications must meet or exceed 20mA typical output current to maintain signal integrity in existing circuit designs.

Environmental Compliance: The substitute must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory requirements for the original application.

Thermal Operating Range: The substitute operating temperature range must support the -40°C ~ 85°C specification of the original part or provide extended range capability.

Engineering Selection Recommendations

The TS393IPT from STMicroelectronics is a qualified substitute for the discontinued TLC352IPWG4 based on the following engineering criteria:

Package and Pinout Compatibility: Both devices utilize the 8-TSSOP surface mount package with identical physical dimensions, enabling direct PCB replacement without layout modification.

Functional Equivalence: The TS393IPT provides dual comparator functionality with output characteristics compatible with CMOS and Open-Drain applications required by the original design.

Electrical Performance: The substitute meets or exceeds the electrical specifications of the main part. The TS393IPT operates across a supply voltage range of 2.7V ~ 16V (single supply) and ±1.35V ~ 8V (dual supply), which encompasses the primary operating region of the TLC352IPWG4. Applications requiring operation below 2.7V single supply voltage would require alternative evaluation.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent component substitution.

Performance Advantages: The TS393IPT demonstrates superior performance characteristics including lower input bias current (1pA versus 5pA) and significantly reduced quiescent current consumption (25µA versus 400µA), providing potential benefits for power-sensitive applications.

Extended Operating Temperature: The TS393IPT supports an operating temperature range of -40°C ~ 125°C, exceeding the -40°C ~ 85°C specification of the original part and providing additional thermal margin for demanding environments.

Product Availability: The TS393IPT is currently in active production status with substantial inventory availability (21,200 pieces), ensuring supply continuity for ongoing production and design support.

Frequently Asked Questions (FAQ)

Q: Can the TS393IPT directly replace the TLC352IPWG4 without PCB modifications?

A: Yes. Both devices use the 8-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width) and compatible pinout configurations, enabling direct substitution without PCB redesign.

Q: What is the primary limitation of the TS393IPT as a substitute?

A: The TS393IPT minimum single supply voltage is 2.7V, compared to the TLC352IPWG4 minimum of 1.4V. Applications requiring operation below 2.7V single supply voltage cannot use this substitute without circuit redesign.

Q: Are the output characteristics of the TS393IPT compatible with the original design?

A: The TS393IPT provides CMOS and Open-Drain output types, which are compatible with the majority of applications using the TLC352IPWG4. The original part also supported MOS and TTL output types; designs specifically requiring these output types should be evaluated for compatibility.

Q: Does the TS393IPT provide equivalent input offset voltage performance?

A: Yes. Both parts specify a maximum input offset voltage of 5mV. The TS393IPT measurement is taken at 10V supply, while the TLC352IPWG4 is measured at 5V supply, but the offset specifications are equivalent for practical circuit design purposes.

Q: What are the power consumption advantages of the TS393IPT?

A: The TS393IPT provides significantly lower quiescent current consumption at 25µA maximum compared to 400µA for the TLC352IPWG4. This 16-fold reduction in quiescent current provides substantial power savings in battery-powered and low-power applications.

Q: Is the TS393IPT suitable for high-temperature applications?

A: The TS393IPT supports an operating temperature range of -40°C ~ 125°C, providing 40°C additional upper temperature margin compared to the TLC352IPWG4 (-40°C ~ 85°C). This extended range makes the TS393IPT suitable for industrial and automotive temperature environments.

Q: What regulatory certifications apply to the TS393IPT?

A: The TS393IPT maintains ROHS3 compliance and REACH unaffected status, matching the regulatory compliance profile of the original TLC352IPWG4 and satisfying environmental requirements for equivalent component substitution.

Q: Are there any dual supply voltage considerations for substitution?

A: Both parts support dual supply operation. The TS393IPT dual supply range (±1.35V ~ 8V) is compatible with the TLC352IPWG4 specification (±0.7V ~ 8V). Applications requiring operation below ±1.35V dual supply voltage would require alternative evaluation.
