Substitute Part Grouping Explanation

Substitution of the FDSD0415-H-1R0M=P3 is determined by the following critical parameters:

• Inductance Value: Must be 1 µH ±20%
• Current Rating: Substitute must support minimum 4.5 A continuous current
• DC Resistance: Lower or equal DCR is acceptable; higher values may impact thermal performance
• Shielding: Shielded construction required for EMI containment
• Mounting Type: Surface mount configuration mandatory
• Physical Footprint: 4.20mm x 4.20mm base dimension required for PCB compatibility
• Compliance: ROHS3 compliance and MSL 1 rating required

The PA4332.102NLT from Pulse Electronics meets all substitution criteria with improved electrical performance characteristics.

Engineering Selection Recommendations

The PA4332.102NLT is a direct functional substitute for the obsolete FDSD0415-H-1R0M=P3. Selection is supported by:

• Compliance Alignment: Both components maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility
• Active Manufacturing Status: PA4332.102NLT is actively produced, providing reliable long-term supply availability
• Electrical Performance: The substitute exceeds the original part specifications in current rating (5.8 A vs 4.5 A) and saturation current (8.5 A vs 5.3 A), while providing superior DC resistance (26mOhm vs 41mOhm)
• Physical Compatibility: Identical base footprint (4.20mm x 4.20mm) ensures PCB layout compatibility; the 0.5mm height increase must be verified against clearance constraints in the application
• Functional Equivalence: Identical inductance value, tolerance, and shielding characteristics maintain circuit performance

Frequently Asked Questions (FAQ)

Q: Can PA4332.102NLT be used as a direct replacement without circuit modification?

A: Yes, provided PCB clearance accommodates the 0.5mm additional height (2.00mm vs 1.50mm seated height). Electrical characteristics are compatible with the original design requirements.

Q: What is the significance of the lower DC resistance in the substitute part?

A: Lower DC resistance (26mOhm vs 41mOhm) reduces resistive losses and heat generation during operation. This represents an improvement over the original specification and does not create compatibility issues.

Q: Are there any compliance or certification differences between the two parts?

A: Both components are ROHS3 compliant with MSL 1 rating. No compliance barriers exist for substitution.

Q: Why is the substitute part taller?

A: The PA4332.102NLT uses a drum core, wirewound construction with iron core material, which results in a 0.5mm height increase compared to the metal core design of the original part. PCB layout clearance must be verified.

Q: Is the PA4332.102NLT available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Verify packaging compatibility with your procurement and assembly requirements.

Q: What is the inductance test frequency difference between the parts?

A: The original part is tested at 100 kHz, while the substitute is tested at 1 MHz. Both maintain the specified 1 µH inductance value within ±20% tolerance at their respective test frequencies.
