Key Parameters

Substitute Part Grouping Explanation

Substitution of the LPWI252010HR33T is determined by the following critical parameters:

• Inductance Value: 330 nH with ±20% tolerance
• Current Rating: Minimum 5.6 A continuous current capability
• Package Format: 1008 (2520 Metric) surface mount
• Shielding: Shielded construction required
• Operating Temperature: -40°C ~ 125°C range
• DC Resistance: Maximum 21 mOhm (or within acceptable circuit tolerance)
• Compliance: ROHS3 compliance required

The MGV252010SR33M-10 meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The MGV252010SR33M-10 is a direct functional equivalent for the obsolete LPWI252010HR33T. Both components share identical inductance values, current ratings, package dimensions, and operating temperature specifications. The substitute part maintains ROHS3 compliance and operates within the same thermal range.

The MGV252010SR33M-10 exhibits a marginally higher saturation current (7.3 A versus 6.8 A) and a 1 mOhm increase in maximum DC resistance (22 mOhm versus 21 mOhm). These variations remain within acceptable engineering tolerances for most applications requiring 330 nH shielded inductors in the 1008 package format.

The substitute part is currently in active production with substantial inventory availability, making it suitable for immediate procurement and integration into existing designs.

Frequently Asked Questions (FAQ)
