PA0431L Equivalent & Substitute Parts

Part Overview

The PA0431L is a 7.8 µH toroidal inductor manufactured by Pulse Electronics, designed for through-hole mounting applications requiring high current handling capability. This fixed inductor delivers 20.5 A current rating with a maximum DC resistance of 5.5 mOhm, operating across the temperature range of -40°C to 130°C. The component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within specified parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the PA0431L is determined by strict equivalence across the following critical parameters:

• Inductance value: 7.8 µH
• Inductance tolerance: ±20%
• Current rating: 20.5 A minimum
• DC resistance: 5.5 mOhm maximum
• Type: Toroidal
• Mounting type: Through hole
• Package configuration: Radial, Vertical (Open)
• Physical dimensions: 0.874" Dia x 0.374" W (22.20mm x 9.50mm)
• Operating temperature range: -40°C ~ 130°C
• Regulatory compliance: ROHS3 Compliant

The PA0431LNL qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format (Tray versus standard packaging) and shielding designation (Unshielded), neither of which affects functional equivalence within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both PA0431L and PA0431LNL maintain Active product status with identical regulatory compliance profiles. Selection between these parts is determined by packaging and inventory requirements rather than electrical or mechanical performance criteria. The PA0431LNL offers higher inventory availability (2489 Pcs versus 739 Pcs) with Tray packaging format. Both components satisfy ROHS3 compliance and REACH unaffected status, making either suitable for applications requiring regulatory adherence. Component selection should prioritize supply chain availability and packaging compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PA0431LNL replace PA0431L in existing designs?

A: Yes. Both components are electrically and mechanically equivalent across all specified parameters including inductance, current rating, DC resistance, physical dimensions, and operating temperature range.

Q: What is the difference between PA0431L and PA0431LNL?

A: The primary differences are packaging format (standard versus Tray) and shielding designation (standard versus Unshielded). Electrical performance and mechanical compatibility remain identical.

Q: Are there any compliance differences between these parts?

A: No. Both components carry identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity ratings.

Q: Does the Unshielded designation on PA0431LNL affect circuit performance?

A: Shielding characteristics are not specified as a substitution criterion for this product category. Selection should be based on application-specific electromagnetic interference requirements.

Q: What packaging format should I specify for new designs?

A: Packaging selection depends on assembly process requirements and inventory management practices. Both Tray and standard packaging formats are available for equivalent electrical performance.
