Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0603205KBETA is determined by the following critical parameters:

Resistance value and tolerance must remain identical at 205 kOhms ±0.1%. Package configuration must be 0603 (1608 Metric) to ensure mechanical and electrical compatibility with existing PCB layouts. Thin film composition is required to maintain the specified temperature coefficient of ±25ppm/°C. The number of terminations must be 2. Moisture Sensitivity Level must be 1 (Unlimited) or equivalent.

Power rating may be equal to or greater than 0.1W, provided all other electrical and mechanical parameters are met. Operating temperature range may be extended beyond -55°C to 125°C without affecting substitution validity. Additional features such as automotive qualification, anti-sulfur coating, or moisture resistance do not disqualify a part from substitution.

Parameter Comparison

The TNPW0603205KBEEA includes automotive AEC-Q200 qualification, anti-sulfur coating, and moisture resistance features.

Selection between these parts should be based on application requirements. The TNPW0603205KBETA remains appropriate for military applications requiring the specified feature set. The TNPW0603205KBEEA is suitable for automotive applications, environments with extended temperature requirements, or designs requiring ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can TNPW0603205KBEEA replace TNPW0603205KBETA in all applications?

A: Yes, provided the application does not have specific requirements for military-grade components or RoHS non-compliant status. The substitute part meets or exceeds all critical electrical parameters.

Q: What is the difference in physical dimensions between these parts?

A: Both parts use the 0603 (1608 Metric) package. The TNPW0603205KBETA measures 0.063" L x 0.033" W (1.60mm x 0.85mm). The TNPW0603205KBEEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm). Both have a maximum seated height of 0.022" (0.55mm).

Q: Are there any compliance differences between these parts?

A: Yes. The TNPW0603205KBETA is RoHS non-compliant. The TNPW0603205KBEEA is ROHS3 compliant. The TNPW0603205KBEEA is also AEC-Q200 qualified for automotive applications.

Q: Can the TNPW0603205KBEEA be used in high-temperature applications?

A: Yes. The TNPW0603205KBEEA operates to 175°C, compared to 125°C for the TNPW0603205KBETA, making it suitable for extended temperature range applications.

Q: Do these parts have identical electrical performance?

A: Yes. Both parts have 205 kOhms resistance, ±0.1% tolerance, and ±25ppm/°C temperature coefficient. The TNPW0603205KBEEA has higher power rating (0.21W versus 0.1W), which does not affect electrical performance in circuits designed for the lower rating.
