KTY82/250,215 PTC Thermistor Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The KTY82/250,215 is a PTC thermistor temperature sensor manufactured by NXP Semiconductors with a nominal resistance of 2 kOhms at 25°C, packaged in SOT-23-3 (TO-236-3, SC-59) surface mount configuration. This component operates across a temperature range of -55°C to 150°C and is classified as obsolete. Due to its obsolete status, equivalent substitute parts are necessary for new designs and ongoing production requirements. Suitable alternatives maintain the same package footprint, surface mount compatibility, and comparable thermal sensing characteristics within overlapping operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KTY82/250,215 are grouped based on the following critical parameters that determine functional compatibility:

Package Compatibility: All substitute parts must use SOT-23-3 (TO-236-3, SC-59) surface mount packaging to ensure direct PCB footprint compatibility.

Operating Temperature Range Overlap: Substitute parts must cover at least the primary operating window of the original component. The KTY82/250,215 operates from -55°C to 150°C. Substitute candidates are evaluated for temperature range overlap within this specification.

Sensor Type and Output: The KTY82/250,215 is a PTC thermistor. Substitute parts in this reference include analog voltage output temperature sensors that provide equivalent thermal sensing functionality in the same package.

Surface Mount Configuration: All candidates maintain surface mount technology (SMT) compatibility for automated assembly processes.

Compliance Standards: RoHS3 compliance and MSL rating (1 - Unlimited) are maintained across all substitute options to ensure regulatory and manufacturing process compatibility.

The substitute parts listed below are organized by their primary operating temperature ranges and sensor output characteristics, all within the SOT-23-3 package constraint.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Extended Temperature Range):

For applications requiring the full -55°C to 150°C operating range of the original KTY82/250,215, no direct substitute with identical temperature coverage exists among the listed parts. However, the following active-status parts provide the widest temperature coverage within the SOT-23-3 package:

TC1047AVNBTR, TC1047VNBTR, LM60QIM3X/NOPB, and MCP9701T-E/TT all operate across -40°C to 125°C, covering the majority of the original component's lower temperature range. These parts are currently in active production status and maintain ROHS3 compliance with MSL 1 rating.

Secondary Substitutes (Limited Temperature Range):

For applications operating within 0°C to 90°C, LM62CIM3X/NOPB and LM62BIM3X/NOPB provide active-status alternatives. LM62CIM3X/NOPB is preferred due to confirmed ROHS3 compliance and MSL 1 rating.

Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard manufacturing processes and regulatory requirements. The DS60R+T2R from Analog Devices Inc./Maxim Integrated is the only active-status part from a major manufacturer other than Texas Instruments or Microchip Technology, offering design flexibility for supply chain diversification.

Frequently Asked Questions (FAQ)

Q: Can I directly replace KTY82/250,215 with any of the listed substitutes?

A: Direct replacement requires matching the SOT-23-3 package footprint, which all listed substitutes provide. However, the original component operates to 150°C while most substitutes operate to 125°C maximum. Verify your application's actual temperature requirements before selection.

Q: What is the key difference between the LM60 and LM62 series?

A: The LM60 series (LM60QIM3/NOPB, LM60QIM3X/NOPB) operates from -40°C to 125°C with 6.25mV/°C resolution. The LM62 series (LM62BIM3/NOPB, LM62BIM3X/NOPB, LM62CIM3X/NOPB) operates from 0°C to 90°C with 15.6mV/°C resolution. Select based on your application's temperature range and required sensitivity.

Q: Why are some parts listed as Obsolete?

A: LM60QIM3/NOPB and LM62BIM3/NOPB are obsolete but remain in inventory. For new designs, select active-status alternatives: LM60QIM3X/NOPB for the -40°C to 125°C range or LM62CIM3X/NOPB for the 0°C to 90°C range.

Q: Are all substitutes RoHS3 compliant?

A: All listed substitutes except LM62BIM3X/NOPB are confirmed ROHS3 compliant. LM62BIM3X/NOPB compliance status is not specified in the provided data. Confirm compliance requirements with your procurement team before selection.

Q: What supply voltage range should I consider?

A: Supply voltage requirements vary by part. TC1047AVNBTR requires 2.5V ~ 5.5V, TC1047VNBTR requires 2.7V ~ 4.4V, and LM60 series parts require 2.7V ~ 10V. Verify your circuit's available supply voltage against the selected substitute's specification.

Q: Can I use MCP9701T-E/TT as a substitute?

A: MCP9701T-E/TT operates from -40°C to 125°C in SOT-23-3 package with active production status. It is suitable for applications not requiring operation above 125°C. Note its supply voltage range is 3.1V ~ 5.5V, which is narrower than some alternatives.

Q: What is the difference between TC1047AVNBTR and TC1047VNBTR?

A: Both operate from -40°C to 125°C with 10mV/°C resolution in SOT-23-3 package. The primary difference is supply voltage: TC1047AVNBTR requires 2.5V ~ 5.5V while TC1047VNBTR requires 2.7V ~ 4.4V. Select based on your circuit's available supply voltage.
