Parameter Comparison

Engineering Selection Recommendations

The Pulse Electronics PA4343.472ANLT is a direct functional substitute for the obsolete Würth Elektronik 831654700. Both components maintain AEC-Q200 automotive qualification and ROHS3 compliance, ensuring regulatory continuity.

The PA4343.472ANLT provides superior electrical performance with 17 A current rating versus 10 A, 8 mOhm maximum DC resistance versus 17 mOhm, and extended operating temperature range of -55°C to 155°C. These enhancements provide design margin and improved thermal performance.

Physical dimensions differ: the substitute measures 14.60mm x 12.60mm with 6.50mm seated height compared to the original 10.00mm x 10.00mm footprint. PCB layout verification is required to confirm clearance and routing compatibility before implementation.

The substitute is available in active production status with 3300 pieces in stock, ensuring supply chain continuity for both new designs and repair applications.

Frequently Asked Questions (FAQ)

Q: Can the Pulse Electronics PA4343.472ANLT be used as a direct replacement for the Würth Elektronik 831654700?

A: Yes, the PA4343.472ANLT meets all electrical and compliance requirements. However, the larger physical footprint (14.60mm x 12.60mm versus 10.00mm x 10.00mm) requires PCB layout verification to confirm component placement and clearance compatibility.

Q: What are the key electrical differences between these parts?

A: The substitute provides enhanced performance: 17 A current rating (versus 10 A), 8 mOhm maximum DC resistance (versus 17 mOhm), and 21 A saturation current (versus 19.5 A). These differences result in lower power dissipation and improved thermal characteristics.

Q: Are both parts automotive qualified?

A: Yes, both components carry AEC-Q200 ratings and ROHS3 compliance, maintaining automotive and environmental regulatory requirements.

Q: What is the impact of the larger package size?

A: The substitute's larger dimensions require verification of available PCB space, trace routing, and component clearance. No electrical performance impact occurs; this is purely a physical layout consideration.

Q: Is the substitute available for immediate use?

A: Yes, the Pulse Electronics PA4343.472ANLT is in active production status with 3300 pieces currently in stock, ensuring supply availability.
