Substitute Part Grouping Explanation

Substitution of the KTY82/220,215 is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the TO-236-3 (SOT-23-3) surface mount package to ensure PCB footprint compatibility.

Sensor Type: The KTY82/220,215 is a PTC thermistor. Direct functional equivalents are analog temperature sensors with local sensing capability and analog voltage output, which provide similar thermal monitoring functionality in the same package form factor.

Operating Temperature Range: The original part operates from -55°C to 150°C. Substitute parts with operating ranges of -40°C to 125°C provide coverage for the majority of industrial and commercial applications, though the upper temperature limit is reduced by 25°C.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and MSL rating of 1 (Unlimited) to ensure regulatory and manufacturing process compatibility.

Electrical Characteristics: Substitute analog temperature sensors provide output via voltage signals with resolutions ranging from 6.25mV/°C to 19.5mV/°C, enabling thermal measurement across defined temperature windows.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Temperature Range):

TC1047AVNBTR and TC1047VNBTR are the preferred substitutes. Both are manufactured by Microchip Technology with active product status, ROHS3 compliance, and MSL rating of 1. These parts operate across -40°C to 125°C, covering the lower portion of the KTY82/220,215 temperature range. TC1047AVNBTR supports supply voltage of 2.5V to 5.5V, while TC1047VNBTR operates at 2.7V to 4.4V. Both provide 10mV/°C resolution with ±2°C to ±3°C accuracy.

Secondary Substitutes (Active Status, Extended Temperature Range):

LM60QIM3X/NOPB (Texas Instruments, Active) and DS60R+T&R (Analog Devices Inc./Maxim Integrated, Active) provide -40°C to 125°C operating range with 6.25mV/°C resolution. LM60QIM3X/NOPB includes AEC-Q100 automotive qualification. DS60R+T&R offers ±2°C to ±3°C accuracy with standby mode feature.

Limited Temperature Range Substitutes (Active Status):

LM62BIM3X/NOPB (National Semiconductor, Active) and LM62CIM3X/NOPB (Texas Instruments, Active) operate within 0°C to 90°C, suitable for applications not requiring the full -55°C to 150°C range of the original part. Both provide 15.6mV/°C resolution with shutdown mode capability.

Avoid for New Designs:

LM60QIM3/NOPB and LM62BIM3/NOPB are classified as obsolete and should not be selected for new production designs despite current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can TC1047AVNBTR directly replace KTY82/220,215 on existing PCBs?

A: Yes, TC1047AVNBTR uses the identical TO-236-3 (SOT-23-3) package and maintains the same three-pin footprint. However, the output signal changes from resistance to analog voltage, requiring circuit redesign to accommodate the voltage output interface.

Q: What is the temperature coverage difference between KTY82/220,215 and substitute parts?

A: The KTY82/220,215 operates from -55°C to 150°C. Most active substitute parts (TC1047 series, LM60 series, DS60R+T&R) operate from -40°C to 125°C, reducing the upper limit by 25°C. LM62 series parts are limited to 0°C to 90°C. Application requirements must determine acceptable temperature range reduction.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitute parts except LM62BIM3X/NOPB are explicitly ROHS3 compliant. LM62BIM3X/NOPB does not specify RoHS status in available documentation. Verify compliance requirements with your procurement process.

Q: What is the difference between TC1047AVNBTR and TC1047VNBTR?

A: Both parts provide identical -40°C to 125°C operating range and 10mV/°C resolution. The primary difference is supply voltage range: TC1047AVNBTR operates at 2.5V to 5.5V, while TC1047VNBTR operates at 2.7V to 4.4V. Select based on available supply voltage in your circuit.

Q: Why do LM62 series parts have a narrower temperature range?

A: LM62 series sensors (LM62BIM3/NOPB, LM62BIM3X/NOPB, LM62CIM3X/NOPB) are designed for 0°C to 90°C applications with higher resolution (15.6mV/°C) compared to LM60 series (6.25mV/°C). The narrower range reflects the intended application space for these sensors.

Q: Is MCP9701T-E/TT suitable as a substitute?

A: MCP9701T-E/TT operates from -10°C to 125°C with 19.5mV/°C resolution and active product status. It provides higher resolution than most alternatives but does not cover temperatures below -10°C. Use only if application minimum temperature is -10°C or higher.

Q: What packaging options are available for substitute parts?

A: All substitute parts are available in TO-236-3 (SOT-23-3) surface mount package. Packaging formats vary: Cut Tape (CT) & Digi-Reel, Tape & Reel (TR), or Bulk. Verify packaging availability with your supplier based on production volume requirements.
