TSX339IPT Equivalent & Substitute Parts

Part Overview

The TSX339IPT is a CMOS comparator integrated circuit manufactured by STMicroelectronics, configured as a 4-element open-drain comparator in a 14-TSSOP surface mount package. This device operates across a wide supply voltage range of 2.7V to 16V (single supply) or ±1.35V to ±8V (dual supply), making it suitable for diverse analog signal processing applications. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance, package compatibility, and operational specifications are maintained across different manufacturing grades or qualifications.

Substitute Part Grouping Explanation

Substitution of the TSX339IPT is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• CMOS technology type with 4 open-drain comparator elements
• Identical supply voltage range: 2.7V ~ 16V (single) or ±1.35V ~ 8V (dual)
• Matching input offset voltage specification of 5mV @ 5V
• Identical input bias current of 10pA @ 5V
• Matching output current capability of 20mA typical
• Identical quiescent current specification of 13µA maximum
• Matching CMRR and PSRR performance of 90dB each
• Operating temperature range of -40°C ~ 125°C

Package and Mechanical Equivalence Criteria:

• 14-TSSOP surface mount package with 0.173" width (4.40mm)
• Tape & Reel packaging format
• Identical supplier device package designation

Compliance and Status Criteria:

• Active product status
• RoHS3 compliance
• MSL rating of 1 (Unlimited)
• REACH unaffected status

The TSX339IYPT qualifies as a parametric equivalent substitute based on complete alignment with all electrical, mechanical, and compliance parameters, with the distinction of automotive-grade qualification and AEC-Q100 certification.

Parameter Comparison

Engineering Selection Recommendations

TSX339IPT Selection: The TSX339IPT is appropriate for general-purpose industrial and consumer applications where standard-grade CMOS comparator performance is required. The device maintains active production status with full RoHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and environmental regulatory compliance.

TSX339IYPT Selection: The TSX339IYPT is the automotive-qualified variant of the TSX339 comparator family, carrying AEC-Q100 certification. This part is suitable for automotive applications and systems requiring automotive-grade component qualification. The electrical and mechanical specifications are identical to the standard-grade TSX339IPT, with the distinction of automotive qualification and testing protocols. Selection of this variant is driven by application requirements for automotive-grade components rather than by differences in electrical performance.

Interchangeability: Both parts are electrically and mechanically interchangeable within their respective application domains. The choice between TSX339IPT and TSX339IYPT is determined by application classification (automotive versus non-automotive) and corresponding qualification requirements, not by functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can the TSX339IYPT be used as a direct replacement for the TSX339IPT?

A: Yes. The TSX339IYPT is electrically and mechanically identical to the TSX339IPT. All electrical parameters, supply voltage ranges, output characteristics, and package specifications are equivalent. The TSX339IYPT carries additional automotive-grade qualification (AEC-Q100), making it suitable for automotive applications. In non-automotive applications, either part can be used interchangeably.

Q: What is the significance of the AEC-Q100 qualification on the TSX339IYPT?

A: AEC-Q100 is an automotive electronics council qualification standard that certifies components for automotive use. The TSX339IYPT has undergone automotive-specific testing and qualification protocols. This certification is required for components used in automotive systems but is not necessary for industrial or consumer applications.

Q: Are the package dimensions identical between TSX339IPT and TSX339IYPT?

A: Yes. Both parts use the 14-TSSOP package with identical dimensions of 0.173" width (4.40mm). Both are surface mount devices supplied in Tape & Reel format. PCB footprints and assembly processes are identical.

Q: What is the operating temperature range for both parts?

A: Both the TSX339IPT and TSX339IYPT operate across the temperature range of -40°C to 125°C, providing equivalent thermal performance across industrial and automotive temperature specifications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TSX339IPT and TSX339IYPT are RoHS3 compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions and full environmental regulatory compliance.

Q: What supply voltage options are available for these comparators?

A: Both parts support single supply operation from 2.7V to 16V or dual supply operation from ±1.35V to ±8V, providing flexibility for diverse circuit configurations.

Q: How many comparator elements are integrated in each device?

A: Both the TSX339IPT and TSX339IYPT contain 4 independent CMOS comparator elements with open-drain outputs in a single 14-TSSOP package.
