PCT2075DP,118 Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The PCT2075DP,118 is a digital temperature sensor manufactured by NXP USA Inc., designed for local temperature measurement across the -55°C to 125°C range with 11-bit resolution and I2C/SMBus output interface. The device operates on supply voltages from 2.7V to 5.5V and is packaged in an 8-TSSOP surface mount configuration. This part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative models are necessary to address specific application requirements including packaging format preferences, supply voltage ranges, accuracy specifications, and inventory availability across different distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCT2075DP,118 is determined by the following critical parameters:

Core Compatibility Requirements:

• Sensor Type: Digital, Local temperature measurement
• Temperature Range: -55°C to 125°C operating capability
• Output Interface: I2C/SMBus serial communication
• Package: 8-TSSOP or 8-MSOP surface mount configuration
• Resolution: 11-bit digital output
• Supply Voltage: Minimum 2.7V operation capability

Secondary Selection Criteria:

• Accuracy specification (±1°C to ±3°C acceptable range)
• Packaging format (Cut Tape, Tube, Tape & Reel)
• Moisture Sensitivity Level (MSL 1 or MSL 3)
• Product Status (Active)
• Regulatory Compliance (ROHS3, REACH Unaffected)

All substitute parts listed maintain full compatibility across core parameters while offering variations in packaging, accuracy grades, and supply voltage ranges to accommodate different procurement and application scenarios.

Parameter Comparison

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (8-TSSOP/MSOP Package):

The Microchip AT30TS series devices (AT30TS74, AT30TS750A, AT30TS75A, AT30TSE752A, AT30TSE754A, AT30TSE758A) provide full functional equivalence to the PCT2075DP,118 across all core electrical parameters. These parts maintain identical 11-bit resolution, I2C/SMBus interface, and -55°C to 125°C operating range. Selection among these variants depends on packaging format requirements and moisture sensitivity specifications. All substitute parts carry ROHS3 compliance and REACH Unaffected status matching the original device.

Packaging Format Selection:

• Cut Tape & Digi-Reel format: AT30TS74-XM8M-T, AT30TS750A-XM8M-T, AT30TS75A-XM8M-T, AT30TSE754A-XM8M-T, AT30TSE758A-XM8M-T
• Tube packaging: AT30TS750A-XM8M-B, AT30TSE752A-XM8M-B
• Bulk packaging: AT30TS74-XM8M-B

Moisture Sensitivity Consideration:

Parts with MSL 1 rating (unlimited moisture exposure tolerance) include AT30TS750A-XM8M-T and AT30TSE758A-XM8M-T. Parts with MSL 3 rating (168-hour moisture exposure limit) include all other Microchip substitutes.

Alternative Package Option:

The MCP9844T-BE/MNY offers I2C temperature monitoring in an 8-WFDFN package with different physical dimensions. This part operates at -40°C to 125°C and requires supply voltage between 1.7V and 3.6V, making it suitable only for applications where the reduced low-temperature range and lower maximum supply voltage are acceptable.

Frequently Asked Questions (FAQ)

Q: Can AT30TS74-XM8M-T directly replace PCT2075DP,118 in existing designs?

A: Yes. Both devices share identical 8-TSSOP/MSOP package dimensions, I2C/SMBus interface, 11-bit resolution, and -55°C to 125°C operating range. Pin-to-pin compatibility is maintained. The AT30TS74 operates at 1.7V minimum supply voltage compared to 2.7V for the PCT2075, providing broader low-voltage compatibility.

Q: What is the difference between AT30TS750A and AT30TS75A variants?

A: Both parts maintain identical electrical specifications including ±1°C to ±3°C accuracy, 11-bit resolution, and I2C/SMBus output. Differences exist only in base product numbering and internal device architecture. Selection between these variants should be based on packaging format and MSL rating availability.

Q: Why does MCP9844T-BE/MNY have a different package type?

A: The MCP9844T-BE/MNY uses an 8-WFDFN Exposed Pad package instead of 8-TSSOP/MSOP. This package type has different physical dimensions and pin layout, requiring PCB redesign. This part is not recommended as a direct replacement unless the application specifically requires the WFDFN package format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and REACH Unaffected designation, matching the regulatory compliance of the original PCT2075DP,118 device.

Q: What does MSL 1 versus MSL 3 mean for component handling?

A: MSL 1 (Unlimited) allows unlimited exposure to moisture before soldering. MSL 3 (168 Hours) restricts moisture exposure to 168 hours maximum before soldering, requiring controlled storage conditions and bake-out procedures if exposure limits are exceeded.

Q: Can I use AT30TS74-XM8M-B (Bulk) instead of Cut Tape format?

A: Yes, from an electrical standpoint. The Bulk packaging format contains the same functional device. Packaging format selection depends on assembly line requirements, tape feeder compatibility, and quantity needs rather than electrical performance.

Q: Is the reduced accuracy of AT30TS74 (±2°C/±3°C) acceptable as a substitute?

A: Accuracy acceptability depends on application requirements. The AT30TS74 provides ±2°C accuracy in the -20°C to 100°C test range, compared to ±1°C for the PCT2075DP,118. Applications requiring ±1°C accuracy should select AT30TS750A, AT30TS75A, AT30TSE752A, AT30TSE754A, or AT30TSE758A variants instead.
