BB153,135

Overview

The NXP USA Inc. KTY84/130,153 is a PTC thermistor sensor designed for temperature measurement applications. It features a nominal resistance of 603 ohms at 25°C and operates within a wide temperature range from -40°C to 300°C. The component is housed in a DO-204AG (DO-34) axial leaded package, suitable for through-hole mounting. This device belongs to the KTY84 series and is manufactured by NXP USA Inc. The part is currently listed as obsolete or discontinued, with multiple product change notices recorded since December 2014. It complies with RoHS3 standards and has a moisture sensitivity level of 1.

Feature Summary

• Positive Temperature Coefficient (PTC) characteristic for reliable thermal sensing
• Wide operational temperature range extending up to 300°C
• Through-hole axial leaded construction for standard PCB integration

Applications

• Temperature monitoring in industrial equipment
• Thermal protection circuits in consumer appliances
• Over-temperature detection in automotive systems

Procurement Notes

Verify current availability status as the component is marked as obsolete. Check for active Product Change Notices (PCN) issued after December 2014 that may affect specifications or manufacturing location. Confirm RoHS3 compliance documentation is available for regulatory requirements. Ensure replacement strategies are evaluated due to discontinuation status.

Selection Notes

Select this component only if legacy compatibility with the KTY84 series is required. Verify that the 603 ohm nominal resistance and DO-34 package dimensions fit the existing design constraints. Consider the limited future supply chain implications when designing new products. Evaluate alternative sensors if long-term production support is necessary.

Part Context

This part belongs to the KTY84 series of silicon PTC temperature sensors produced by NXP. These devices are known for their linear resistance-temperature characteristics over specific ranges. The KTY84 family is widely used in cost-sensitive applications requiring robust thermal sensing without complex signal conditioning.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided source data beyond general obsolescence notices. Designers should consult official NXP documentation for qualified replacements or evaluate generic PTC thermistors with matching 603 ohm @ 25°C specifications and DO-34 packaging.
