Parameter Comparison

Engineering Selection Recommendations

The P1K0.0805.2ST.A.S is the direct substitute for the obsolete P1K0.0805.2P.A.S. Both components are manufactured by Innovative Sensor Technology, USA Division and maintain identical electrical specifications for platinum RTD temperature sensing applications.

Selection Basis:

The substitute part satisfies all functional requirements through equivalent resistance value (1 kOhms @ 0°C), identical RTD material composition (Platinum), matching temperature coefficient (3850ppm/°C), and identical operating temperature range (-50°C ~ +150°C). Both components feature surface mount termination with SMD (SMT) tabs and 0805 package form factor.

The P1K0.0805.2ST.A.S offers the advantage of active product status, ensuring continued availability and supply chain reliability. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), supporting equivalent environmental and regulatory requirements.

The current rating difference (0.3 mA for the main part versus 1 mA for the substitute) reflects the substitute's capability to operate at higher current levels while maintaining the same resistance and temperature coefficient characteristics.

Frequently Asked Questions (FAQ)

Q: Can the P1K0.0805.2ST.A.S directly replace the P1K0.0805.2P.A.S in existing designs?

A: Yes. Both components share identical electrical specifications including 1 kOhms resistance at 0°C, platinum RTD material, 3850ppm/°C temperature coefficient, and -50°C to +150°C operating range. Surface mount termination and 0805 package form factor are equivalent across both parts.

Q: What is the difference between the 2-SMD, No Lead package and the 0805 (2012 Metric) package designation?

A: Both designations refer to the same 0805 form factor used in surface mount applications. The 2-SMD, No Lead and 0805 (2012 Metric) nomenclature represent identical physical and electrical packaging specifications.

Q: Why does the substitute part have a higher current rating (1 mA versus 0.3 mA)?

A: The substitute part P1K0.0805.2ST.A.S is rated for 1 mA maximum current, while the original part is rated for 0.3 mA. This represents an enhanced capability of the substitute component. Applications using the original part at or below 0.3 mA will operate within the substitute's specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the P1K0.0805.2P.A.S and P1K0.0805.2ST.A.S are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these components?

A: Both components are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Why is the original part listed as obsolete?

A: The P1K0.0805.2P.A.S is classified as obsolete, indicating discontinued production. The P1K0.0805.2ST.A.S maintains active product status with ongoing manufacturing and availability.
