Key Parameters

Substitute Part Grouping Explanation

Substitution for the TNPW0805232KBETA is determined by the following critical parameters:

Resistance value and tolerance must remain at 232 kOhms ±0.1%. The package must be 0805 (2012 Metric) with identical physical dimensions (0.079" L x 0.049" W, 0.022" max height). Composition must be thin film. Temperature coefficient must be ±25ppm/°C. The number of terminations must be 2. Moisture Sensitivity Level must be 1 (Unlimited).

Power rating may be equal to or greater than 0.125W, as higher power ratings provide equivalent or superior performance in the same package footprint. Operating temperature range may be extended beyond -55°C ~ 125°C without affecting substitution validity. Additional features such as anti-sulfur coating, automotive qualification (AEC-Q200), or moisture resistance do not prevent substitution but represent enhanced capabilities.

Parameter Comparison

Engineering Selection Recommendations

The TNPW0805232KBEEA is a valid substitute for the TNPW0805232KBETA. Both parts are manufactured by Vishay Dale and maintain identical electrical specifications (232 kOhms ±0.1%, ±25ppm/°C) and mechanical compatibility (0805 package, identical dimensions).

The TNPW0805232KBEEA provides enhanced capabilities: higher power rating (0.26W versus 0.125W), extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 125°C), anti-sulfur coating, automotive AEC-Q200 qualification, and moisture resistance. The substitute part is RoHS3 compliant, whereas the original part is RoHS non-compliant.

Selection between these parts depends on application requirements. The TNPW0805232KBETA remains suitable for applications within its specified operating range. The TNPW0805232KBEEA is appropriate for applications requiring higher power dissipation capability, extended temperature operation, automotive qualification, or RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805232KBEEA replace TNPW0805232KBETA in existing designs?

A: Yes. Both parts share identical resistance (232 kOhms), tolerance (±0.1%), package (0805), dimensions, and temperature coefficient (±25ppm/°C). The substitute part has higher power rating and extended temperature range, making it functionally compatible for the same circuit applications.

Q: What is the difference in power rating between these parts?

A: TNPW0805232KBETA is rated at 0.125W (1/8W), while TNPW0805232KBEEA is rated at 0.26W. The higher power rating of the substitute part allows greater power dissipation in the same physical package without thermal stress.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0805 (2012 Metric) package with dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.022" (0.55mm). They are mechanically interchangeable on PCBs designed for 0805 resistors.

Q: What is the temperature operating range difference?

A: TNPW0805232KBETA operates from -55°C to 125°C. TNPW0805232KBEEA extends this range to -55°C to 175°C, providing capability for higher-temperature applications.

Q: Does RoHS compliance affect substitution?

A: TNPW0805232KBETA is RoHS non-compliant, while TNPW0805232KBEEA is RoHS3 compliant. Applications requiring RoHS3 compliance must use the substitute part. For applications without RoHS requirements, both parts are electrically equivalent.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both TNPW0805232KBETA and TNPW0805232KBEEA are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
