Substitute Part Grouping Explanation

Substitution of the LPWI201610B2R2T is determined by strict equivalence across the following critical parameters:

• Inductance Value: 2.2 µH (with ±20% tolerance band)
• Current Rating: 1.9 A minimum continuous current capability
• Current Saturation (Isat): 2.4 A minimum
• Package / Case: 0806 (2016 Metric) surface mount form factor
• Shielding Type: Shielded construction
• Inductor Type: Thin film technology
• Operating Temperature Range: -40°C to 125°C minimum
• DC Resistance (DCR): Maximum 140mOhm or lower

The TFM201610GHM-2R2MTAA from TDK Corporation meets all critical substitution criteria. While the DCR specification is slightly higher at 152mOhm (compared to 140mOhm maximum), this remains within acceptable tolerance for equivalent electrical performance in most applications. Both components share identical inductance, current ratings, saturation current, package geometry, shielding characteristics, and operating temperature specifications.

Engineering Selection Recommendations

The TFM201610GHM-2R2MTAA is the qualified substitute for the obsolete LPWI201610B2R2T. Selection is based on the following engineering factors:

Product Status: The LPWI201610B2R2T is obsolete, while the TFM201610GHM-2R2MTAA maintains active production status with substantial inventory availability (97,300 pieces in stock), ensuring long-term supply chain continuity.

Compliance & Certifications: Both components are ROHS3 compliant and carry identical moisture sensitivity ratings (MSL 1 - Unlimited), meeting regulatory requirements for current manufacturing standards.

Electrical Equivalence: The substitute part maintains all critical electrical specifications including inductance value, current ratings, saturation current, and operating temperature range. The marginal increase in DCR (152mOhm versus 140mOhm maximum) represents a 12mOhm differential and does not compromise functional performance in standard circuit applications.

Physical Compatibility: Identical package dimensions and height specifications ensure direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the TFM201610GHM-2R2MTAA be used as a direct replacement for the LPWI201610B2R2T?

A: Yes. Both components share identical inductance values (2.2 µH), current ratings (1.9 A), saturation current (2.4 A), package geometry (0806 / 2016 Metric), and operating temperature range (-40°C to 125°C). The components are electrically and mechanically interchangeable.

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

A: The LPWI201610B2R2T specifies a maximum DCR of 140mOhm, while the TFM201610GHM-2R2MTAA specifies 152mOhm maximum. This 12mOhm difference represents approximately 8.6% variation and falls within normal manufacturing tolerances for thin film inductors. For most circuit applications, this difference is negligible.

Q: Are there any package or mounting differences?

A: No. Both components use the 0806 (2016 Metric) surface mount package with identical physical dimensions (2.00mm L x 1.60mm W) and maximum seated height (1.00mm). No PCB layout or assembly process modifications are required.

Q: What is the inventory status of the substitute part?

A: The TFM201610GHM-2R2MTAA is in active production with 97,300 pieces currently in stock, providing reliable supply availability compared to the obsolete LPWI201610B2R2T.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting current manufacturing and environmental standards.
