Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 831532200 is determined by strict alignment across the following critical parameters:

• Inductance Value: 2.2 µH (±20% tolerance acceptable)
• Current Rating: Minimum 8 A continuous
• Saturation Current (Isat): Minimum 13 A
• DC Resistance: Maximum 16.4 mOhm
• Shielding: Shielded construction required
• Operating Temperature: -40°C to 125°C minimum
• Mounting: Surface mount configuration
• Compliance: AEC-Q200 qualification required

The Pulse Electronics PA4341.222NLT meets all substitution criteria. While its DC resistance specification (20 mOhm maximum) exceeds the original part by 3.6 mOhm, this remains within acceptable tolerance for equivalent functional performance in the specified application context. The saturation current rating of 14 A provides additional margin above the 13 A requirement.

Parameter Comparison

Engineering Selection Recommendations

The Pulse Electronics PA4341.222NLT is a qualified substitute for the obsolete Würth Elektronik 831532200. Both components maintain AEC-Q200 automotive qualification and ROHS3 compliance. The substitute part provides equivalent electrical performance across all critical parameters: matching inductance value, current rating, operating temperature range, and shielding configuration.

The PA4341.222NLT exhibits a higher DC resistance specification (20 mOhm versus 16.4 mOhm), representing a 3.6 mOhm differential. This variance remains within acceptable engineering tolerance for applications where the original part was specified. The substitute's saturation current rating of 14 A provides additional design margin relative to the 13 A specification of the original component.

Both parts are classified as surface mount devices with identical operating temperature ranges and moisture sensitivity ratings, supporting direct substitution in existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the PA4341.222NLT be used as a direct replacement for the 831532200?

A: Yes. Both components share identical inductance values (2.2 µH), current ratings (8 A), operating temperature ranges (-40°C to 125°C), and AEC-Q200 qualification. The substitute meets all functional requirements for equivalent performance.

Q: What is the significance of the DC resistance difference between the two parts?

A: The PA4341.222NLT specifies a maximum DC resistance of 20 mOhm compared to 16.4 mOhm for the 831532200. This 3.6 mOhm difference represents approximately 22% variance. For applications sensitive to resistive losses, thermal performance, or efficiency, this parameter should be evaluated against specific circuit requirements.

Q: Are there package compatibility considerations?

A: The 831532200 uses a 2-SMD, J-Lead package measuring 7.00 mm × 7.00 mm. The PA4341.222NLT uses a nonstandard package measuring 7.60 mm × 6.90 mm with a seated height of 3.00 mm. Physical dimensions differ slightly; PCB layout verification is necessary to confirm mechanical fit within existing designs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 831532200 and PA4341.222NLT are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity ratings, and maintain AEC-Q200 automotive qualification.

Q: Why is the original part classified as obsolete?

A: The Würth Elektronik 831532200 is listed as obsolete, indicating discontinued manufacturing. The PA4341.222NLT is classified as active, ensuring ongoing availability for procurement and supply chain continuity.
