Substitute Part Grouping Explanation

Substitution of the LPWI252010HR47T is determined by strict equivalence across the following critical parameters:

• Inductance Value: 470 nH ±20%
• Current Rating: 5.2 A minimum continuous current capability
• Package Format: 1008 (2520 Metric) surface mount
• Shielding: Shielded construction required
• Physical Dimensions: 0.098" L x 0.079" W (2.50mm x 2.00mm), Height 0.039" (1.00mm) maximum
• Operating Temperature: -40°C ~ 125°C
• Regulatory Compliance: ROHS3 Compliant

The MGV252010SR47M-10 from Laird-Signal Integrity Products meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The MGV252010SR47M-10 is the qualified substitute for the obsolete LPWI252010HR47T. Both components maintain identical electrical specifications for inductance value, current rating, and operating temperature range. The substitute part is manufactured by an active supplier with current product status, ensuring long-term availability and supply chain continuity.

Both parts are ROHS3 compliant and share identical package dimensions and mounting characteristics, enabling direct board-level substitution without layout modifications. The DC resistance differential of 2 mOhm (27 mOhm versus 29 mOhm maximum) and saturation current variance of 0.3 A (6 A versus 5.7 A) remain within acceptable engineering tolerances for equivalent circuit performance in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the MGV252010SR47M-10 be used as a direct replacement for the LPWI252010HR47T?

A: Yes. Both components share identical inductance values, current ratings, package dimensions, and operating temperature ranges. The parts are mechanically and electrically interchangeable at the board level.

Q: What is the difference between thin film and molded inductor construction?

A: The LPWI252010HR47T uses thin film construction, while the MGV252010SR47M-10 uses molded construction. Both are shielded designs suitable for the same application space. The construction difference does not affect substitution eligibility when electrical and mechanical parameters are equivalent.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant. The main part carries MSL 1 (Unlimited) rating, while the substitute part is listed as Not Applicable for MSL. Both meet the same regulatory requirements for the specified operating environment.

Q: What is the significance of the DC resistance difference?

A: The DC resistance difference of 2 mOhm (27 mOhm maximum versus 29 mOhm maximum) represents a 7.4% variance. This falls within normal manufacturing tolerances and does not prevent functional equivalence in standard circuit applications.

Q: Why is the main part obsolete?

A: Product obsolescence is determined by the manufacturer. The availability of the active substitute part (MGV252010SR47M-10) provides a direct path for continued production support without design changes.
