Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805324KBEEA is determined by the following critical parameters:

• Resistance value: 324 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Automotive qualification: AEC-Q200 (required for automotive applications)
• Temperature coefficient: ±25ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (required for regulatory compliance)

The ERA-6AEB3243V from Panasonic Electronic Components meets all critical substitution criteria. While the power rating differs (0.125W versus 0.26W), this represents a derating condition acceptable in applications where the original 0.26W specification provides design margin. The substitute maintains identical resistance, tolerance, package, composition, temperature coefficient, and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-6AEB3243V qualifies as a direct substitute for the TNPW0805324KBEEA based on matching electrical specifications, identical package format, and equivalent automotive qualification. Both components are ROHS3 compliant and maintain the same moisture sensitivity rating. The operating temperature range of the Panasonic substitute extends to 155°C versus 175°C for the Vishay part; applications operating above 155°C require the original TNPW0805324KBEEA. The reduced power rating of the ERA-6AEB3243V (0.125W) is acceptable in circuits where actual power dissipation does not exceed this threshold. Component selection should be based on application power requirements, temperature operating conditions, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the ERA-6AEB3243V replace the TNPW0805324KBEEA in all applications?

A: The ERA-6AEB3243V is electrically and mechanically compatible for applications where operating temperature does not exceed 155°C and power dissipation does not exceed 0.125W. Applications requiring operation above 155°C or higher power dissipation require the original TNPW0805324KBEEA.

Q: Are there physical compatibility concerns between these parts?

A: Both components use the 0805 (2012 Metric) package with identical length and width dimensions (0.079" x 0.049"). The seated height differs by 0.002" (0.05mm), which does not affect PCB assembly or clearance in standard designs.

Q: Do both parts meet automotive qualification requirements?

A: Yes, both the TNPW0805324KBEEA and ERA-6AEB3243V carry AEC-Q200 automotive qualification and are ROHS3 compliant.

Q: What is the significance of the power rating difference?

A: The TNPW0805324KBEEA is rated for 0.26W while the ERA-6AEB3243V is rated for 0.125W. The substitute can be used in applications where actual power dissipation remains below 0.125W. Designs utilizing the full 0.26W capability require the original part.

Q: Are the temperature coefficients identical?

A: Yes, both components specify ±25ppm/°C temperature coefficient, ensuring equivalent frequency stability and thermal performance characteristics.
