Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805330RBETA is determined by the following criteria:

• Resistance value must be 330 Ohms
• Tolerance must be ±0.1%
• Package must be 0805 (2012 Metric)
• Composition must be thin film
• Temperature coefficient must be ±25ppm/°C
• Number of terminations must be 2
• Moisture Sensitivity Level must be 1 (Unlimited)

The substitute part TNPW0805330RBEEA meets all these criteria. While the substitute exhibits higher power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 125°C), these represent enhanced capabilities that do not restrict substitution in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The TNPW0805330RBEEA serves as a direct substitute for the TNPW0805330RBETA in applications where the original part is specified. The substitute maintains identical electrical characteristics (resistance, tolerance, temperature coefficient) and mechanical compatibility (0805 package, footprint, termination count).

The TNPW0805330RBEEA is ROHS3 compliant and REACH unaffected, whereas the original part is RoHS non-compliant and REACH affected. The substitute incorporates anti-sulfur and moisture-resistant properties with AEC-Q200 automotive qualification, providing enhanced reliability in demanding environments.

The extended operating temperature range of the substitute (-55°C ~ 175°C) accommodates applications requiring higher temperature performance without modification to circuit design.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805330RBEEA replace TNPW0805330RBETA in existing designs?

A: Yes. Both parts share identical resistance (330 Ohms), tolerance (±0.1%), package (0805), and temperature coefficient (±25ppm/°C). The substitute's higher power rating and extended temperature range do not restrict its use in applications designed for the original part.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.079" L x 0.049" W (2.00mm x 1.25mm) with maximum seated height of 0.022" (0.55mm). They are mechanically interchangeable on PCB layouts designed for 0805 package components.

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

A: The original TNPW0805330RBETA is rated for 0.125W (1/8W), while the substitute TNPW0805330RBEEA is rated for 0.26W. The substitute can dissipate approximately twice the power, making it suitable for higher-power applications without thermal derating.

Q: Does the substitute meet automotive standards?

A: The TNPW0805330RBEEA carries AEC-Q200 automotive qualification and incorporates anti-sulfur and moisture-resistant features. The original TNPW0805330RBETA does not specify automotive qualification.

Q: What is the difference in compliance status?

A: The substitute TNPW0805330RBEEA is ROHS3 compliant and REACH unaffected. The original TNPW0805330RBETA is RoHS non-compliant and REACH affected. For applications requiring regulatory compliance, the substitute is the appropriate choice.
