Substitute Part Grouping Explanation

Substitution of the FDSD0412-H-2R2M=P3 with PA4332.222NLT is based on the following critical parameters:

• Inductance Value: Both parts specify 2.2 µH with ±20% tolerance, ensuring equivalent inductive performance
• Inductance Tolerance: Identical ±20% tolerance maintains circuit design margins
• Type & Construction: Both are drum core, wirewound, shielded inductors with identical core material classification for electromagnetic performance
• Mounting Type: Both are surface mount components compatible with standard PCB assembly processes
• Physical Footprint: Identical planar dimensions (0.165" L x 0.165" W / 4.20mm x 4.20mm) ensure PCB layout compatibility
• Regulatory Compliance: Both are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings

The PA4332.222NLT provides superior electrical performance with higher current ratings (4.3 A vs. 2.8 A) and lower DC resistance (48 mOhm vs. 84 mOhm), making it a direct functional upgrade while maintaining all critical substitution parameters.

Parameter Comparison

Engineering Selection Recommendations

The PA4332.222NLT is the designated substitute for the obsolete FDSD0412-H-2R2M=P3 based on the following engineering criteria:

Regulatory & Compliance Alignment: Both components maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in production environments.

Product Status: The PA4332.222NLT carries active product status with confirmed inventory availability (4064 pcs), whereas the FDSD0412-H-2R2M=P3 is obsolete. This transition ensures long-term supply chain viability and manufacturing continuity.

Electrical Performance: The substitute part delivers enhanced electrical characteristics with 53.6% higher current rating (4.3 A vs. 2.8 A) and 42.9% lower DC resistance (48 mOhm vs. 84 mOhm), providing improved thermal performance and reduced power dissipation in equivalent circuit applications.

Physical Compatibility: Identical planar footprint (4.20mm x 4.20mm) ensures direct PCB layout compatibility. The increased seated height (2.00mm vs. 1.20mm) requires verification of vertical clearance in the target assembly, but does not affect electrical substitution validity.

Moisture Sensitivity: Both components specify MSL 1 (Unlimited), maintaining identical handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can PA4332.222NLT directly replace FDSD0412-H-2R2M=P3 on existing PCBs?

A: Yes, for electrical function. Both components share identical inductance (2.2 µH ±20%), current rating compatibility (PA4332.222NLT rated higher at 4.3 A), and planar footprint (4.20mm x 4.20mm). Verify vertical clearance, as PA4332.222NLT has a maximum seated height of 2.00mm compared to 1.20mm for the original part.

Q: What are the key substitution criteria for this inductor category?

A: Substitution validity is determined by: (1) identical inductance value and tolerance, (2) drum core wirewound construction type, (3) shielded configuration, (4) surface mount mounting type, (5) matching planar dimensions, and (6) equivalent regulatory compliance (ROHS3, REACH status, MSL rating).

Q: Does the lower DC resistance of PA4332.222NLT affect circuit operation?

A: No. Lower DC resistance (48 mOhm vs. 84 mOhm) reduces resistive losses and improves efficiency. This is a performance enhancement that does not compromise circuit compatibility.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in nonstandard packages. PA4332.222NLT is available in Tape & Reel (TR) packaging, whereas FDSD0412-H-2R2M=P3 packaging format is not specified. Confirm packaging requirements with your procurement process.

Q: What is the operating temperature range for the substitute part?

A: PA4332.222NLT operates across -40°C to 125°C. The original FDSD0412-H-2R2M=P3 does not specify an operating temperature range. Verify that the substitute's temperature range meets your application requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both FDSD0412-H-2R2M=P3 and PA4332.222NLT are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment for production and export applications.
