Substitute Part Grouping Explanation

Substitution eligibility for the LPWI201610S2R2T is determined by strict alignment across the following critical parameters:

• Inductance Value: 2.2 µH (exact match required)
• Tolerance: ±20% (matching specification)
• Package / Case: 0806 (2016 Metric) (physical and electrical compatibility)
• Shielding Type: Shielded (electromagnetic performance requirement)
• Operating Temperature Range: -40°C ~ 125°C (minimum requirement)
• Current Rating: Equal to or greater than 1.7 A
• DC Resistance: Equal to or less than 150mOhm Max
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The substitute part TFM201610GHM-2R2MTAA meets all substitution criteria, offering improved current handling capability (1.9 A vs. 1.7 A) and comparable DC resistance (152mOhm vs. 150mOhm), while maintaining identical package geometry and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The TFM201610GHM-2R2MTAA from TDK Corporation is a direct substitute for the obsolete LPWI201610S2R2T. The substitute part maintains identical electrical specifications for inductance, tolerance, and operating temperature range, with enhanced current handling characteristics (1.9 A vs. 1.7 A) and improved saturation current (2.4 A vs. 1.5 A). Physical dimensions and package geometry are identical, ensuring PCB layout compatibility without modification.

Both components meet ROHS3 compliance requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings, confirming equivalent environmental and regulatory suitability. The substitute part's active product status ensures long-term availability and supply chain continuity, addressing the obsolescence of the original component.

Frequently Asked Questions (FAQ)

Q: Can the TFM201610GHM-2R2MTAA be used as a direct replacement for the LPWI201610S2R2T without PCB modifications?
