KTY82/120,215 Equivalent & Substitute Parts
Part Overview
The KTY82/120,215 is a PTC thermistor temperature sensor manufactured by NXP Semiconductors with a nominal resistance of 1 kOhm at 25°C, packaged in SOT-23-3 (TO-236-3, SC-59). The device operates across -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 must maintain compatible package geometry, operating temperature range overlap, and similar electrical characteristics for direct circuit substitution.

Substitute Part Grouping Explanation
Substitution logic for the KTY82/120,215 is based on the following criteria:
Package Compatibility: All substitute parts must use SOT-23-3 (TO-236-3, SC-59) package to ensure mechanical and electrical compatibility with existing PCB layouts.
Operating Temperature Range: Substitute parts must support temperature ranges that encompass or overlap with the original -55°C to 150°C specification. Parts with narrower ranges may be acceptable if the application operates within their specified limits.
Sensor Type and Output: The KTY82/120,215 is a PTC thermistor. Substitute parts listed are analog voltage output temperature sensors, which provide functionally equivalent temperature sensing capability in the same package form factor.
Compliance Standards: All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring environmental and moisture sensitivity compatibility.
Product Status Consideration: Active status parts are preferred for new designs; obsolete parts may be used where inventory is available but carry supply chain risk.

Engineering Selection Recommendations
Primary Substitutes (Active Status, Full Temperature Range Coverage):
TC1047AVNBTR and TC1047VNBTR (Microchip Technology) are the preferred substitutes. Both are active products with -40°C to 125°C operating range, SOT-23-3 package compatibility, and ROHS3 compliance. TC1047AVNBTR operates at 2.5V to 5.5V supply; TC1047VNBTR operates at 2.7V to 4.4V supply. Selection depends on available supply voltage in the target application.
LM60QIM3X/NOPB (Texas Instruments) is an active alternative with -40°C to 125°C range, AEC-Q100 automotive qualification, and ROHS3 compliance. This part is suitable for automotive and industrial applications requiring extended temperature coverage.
DS60R+T&R (Analog Devices Inc./Maxim Integrated) provides -40°C to 125°C coverage with active product status and ROHS3 compliance. This part includes standby mode functionality.
Secondary Substitutes (Limited Temperature Range):
LM62CIM3X/NOPB and LM62BIM3X/NOPB (Texas Instruments and National Semiconductor) operate within 0°C to 90°C range. These parts are suitable only for applications where the operating temperature does not exceed 90°C and does not fall below 0°C.
Obsolete Alternatives (Inventory Dependent):
LM60QIM3/NOPB and LM62BIM3/NOPB are obsolete but may be available from existing inventory. These should be considered only when new active stock is unavailable and supply chain continuity is not a concern.
Frequently Asked Questions (FAQ)
Q: Can the KTY82/120,215 be directly replaced with TC1047AVNBTR?
A: Yes. Both parts use SOT-23-3 package, operate within overlapping temperature ranges (-40°C to 125°C for TC1047AVNBTR covers the KTY82/120,215's -55°C to 150°C range partially), and maintain ROHS3 compliance. Circuit design must account for the change from resistance output (KTY82/120,215) to analog voltage output (TC1047AVNBTR).
Q: What is the key difference between TC1047AVNBTR and TC1047VNBTR?
A: The primary difference is supply voltage range. TC1047AVNBTR operates at 2.5V to 5.5V; TC1047VNBTR operates at 2.7V to 4.4V. Both provide identical temperature sensing performance and package compatibility. Selection depends on the available supply voltage in your circuit.
Q: Why are LM62 series parts listed as secondary substitutes?
A: LM62 series parts (LM62BIM3/NOPB, LM62BIM3X/NOPB, LM62CIM3X/NOPB) operate within 0°C to 90°C range, which is narrower than the KTY82/120,215's -55°C to 150°C specification. These parts are suitable only for applications operating entirely within the 0°C to 90°C window.
Q: Are all substitute parts ROHS3 compliant?
A: All listed substitutes except LM62BIM3X/NOPB are explicitly ROHS3 compliant. LM62BIM3X/NOPB RoHS status is not specified in the provided data. Verify compliance documentation with the supplier before use in RoHS-regulated applications.
Q: What is the MSL rating for substitute parts?
A: All substitute parts carry MSL Level 1 (Unlimited) rating, matching the KTY82/120,215 specification. This indicates no moisture sensitivity restrictions during storage and handling.
Q: Which substitute part has the widest operating temperature range?
A: TC1047AVNBTR and TC1047VNBTR both provide -40°C to 125°C range. While this does not fully cover the KTY82/120,215's -55°C to 150°C specification, it represents the widest range available among the listed substitutes and covers most industrial and commercial applications.
Q: Can I use LM60QIM3/NOPB as a substitute despite its obsolete status?
A: LM60QIM3/NOPB is functionally compatible (SOT-23-3 package, -40°C to 125°C range, ROHS3 compliant) but carries obsolete product status. Use only if existing inventory is available and supply chain continuity is not required. For new designs, select active alternatives such as LM60QIM3X/NOPB or TC1047AVNBTR.
