Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805845KBEEA is determined by the following critical parameters:

• Resistance value: 845 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Automotive Certification: AEC-Q200 (required for automotive applications)
• RoHS Compliance: ROHS3 Compliant (required for regulatory compliance)

The ERA-6AEB8453V qualifies as a direct substitute based on matching resistance, tolerance, package, composition, temperature coefficient, and automotive certification. Power rating differences are evaluated separately based on circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The ERA-6AEB8453V is a qualified substitute for the TNPW0805845KBEEA based on matching electrical specifications, package dimensions, and automotive certifications. Both components are ROHS3 compliant, AEC-Q200 rated, and feature identical resistance, tolerance, and temperature coefficient values.

The primary consideration for substitution is power dissipation. The TNPW0805845KBEEA is rated at 0.26W, while the ERA-6AEB8453V is rated at 0.125W. Substitution is valid only when circuit power dissipation does not exceed 0.125W at the resistor location.

The operating temperature range differs: TNPW0805845KBEEA operates to 175°C, while ERA-6AEB8453V operates to 155°C. Substitution is valid only when the application maximum temperature does not exceed 155°C.

Both components maintain identical physical dimensions and termination specifications, ensuring mechanical compatibility in 0805 footprints.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB8453V replace TNPW0805845KBEEA in all applications?

A: Substitution is valid when circuit power dissipation does not exceed 0.125W and maximum operating temperature does not exceed 155°C. The TNPW0805845KBEEA provides higher power rating (0.26W) and extended temperature range (-55°C to 175°C) compared to ERA-6AEB8453V (-55°C to 155°C).

Q: Are the physical dimensions identical?

A: Both components use the 0805 (2012 Metric) package with identical length and width (0.079" L x 0.049" W). Maximum seated height differs slightly: TNPW0805845KBEEA is 0.022" (0.55mm) and ERA-6AEB8453V is 0.024" (0.60mm). This difference is negligible for standard PCB assembly.

Q: Do both parts meet automotive requirements?

A: Yes. Both TNPW0805845KBEEA and ERA-6AEB8453V are AEC-Q200 qualified and suitable for automotive applications.

Q: What is the tolerance specification for both parts?

A: Both components feature ±0.1% tolerance with ±25ppm/°C temperature coefficient, ensuring identical precision characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both TNPW0805845KBEEA and ERA-6AEB8453V are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.
