Key Parameters

Substitute Part Grouping Explanation

Substitution of the LPWI201608SR24T is determined by strict equivalence across the following parameters:

• Inductance value: 240 nH with ±20% tolerance
• Package format: 0806 (2016 Metric) surface mount
• Shielding requirement: Shielded construction
• Operating temperature range: -40°C ~ 125°C minimum
• Current rating: Equal to or greater than 4.2 A
• DC resistance: Equal to or less than 25 mOhm
• Saturation current: Equal to or greater than 4.6 A
• RoHS compliance: ROHS3 Compliant

The SRP2010-R24M from Bourns Inc. meets all substitution criteria and is classified as an active product with improved availability.

Parameter Comparison

Engineering Selection Recommendations

The SRP2010-R24M is the qualified substitute for the obsolete LPWI201608SR24T. Selection is based on the following factors:

• Both components maintain identical inductance specifications (240 nH ±20%)
• Electrical performance of the SRP2010-R24M exceeds minimum requirements: current rating increased from 4.2 A to 4.5 A, saturation current increased from 4.6 A to 5.6 A, and DC resistance reduced from 25 mOhm to 21 mOhm
• Package and footprint compatibility is confirmed: both use 0806 (2016 Metric) surface mount format with identical lateral dimensions
• Height difference of 0.006" (0.15mm) is within typical PCB assembly tolerances
• Both components maintain ROHS3 compliance and MSL 1 rating
• The SRP2010-R24M is an active product with established supply chain availability

Frequently Asked Questions (FAQ)

Q: Can the SRP2010-R24M be used as a direct replacement for the LPWI201608SR24T?

A: Yes. Both components share identical inductance values, tolerance specifications, package format, and operating temperature range. The SRP2010-R24M provides equal or superior electrical performance across all critical parameters.

Q: What is the height difference between these components?

A: The LPWI201608SR24T has a maximum seated height of 0.031" (0.80mm), while the SRP2010-R24M has a maximum seated height of 0.037" (0.95mm). This 0.006" (0.15mm) difference is within standard PCB assembly clearance tolerances and does not affect board-level compatibility.

Q: Are there compliance differences between the two parts?

A: No. Both components are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity ratings, and operate across the identical temperature range of -40°C to 125°C.

Q: Why is the DC resistance lower on the SRP2010-R24M?

A: The SRP2010-R24M uses drum core wirewound construction with iron powder core material, compared to the thin film metal composite core of the LPWI201608SR24T. This design difference results in lower DC resistance (21 mOhm vs. 25 mOhm) while maintaining the same inductance value.

Q: What is the availability status of each part?

A: The LPWI201608SR24T is obsolete and no longer in active production. The SRP2010-R24M is an active product with established supply chain availability.
