• Inductance tolerance: ±20%
• Shielding requirement: Shielded
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 125°C minimum
• Inductance test frequency: 100 kHz

Secondary Compatibility Factors:

• Current rating: Minimum 4.9 A continuous
• Saturation current: Minimum 6.9 A
• DC resistance: Acceptable range based on circuit requirements

• Moisture sensitivity: MSL 1 or equivalent

The three substitute parts listed meet the primary inductance and environmental specifications. Variations in current rating, DC resistance, and physical dimensions reflect different design approaches within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

MPIA4020V2-1R5-R (Eaton - Electronics Division)

This substitute is the closest functional equivalent, manufactured by the same supplier as the obsolete part. It maintains identical inductance, tolerance, and operating temperature specifications. The current rating of 5 A exceeds the main part requirement of 4.9 A, and saturation current of 6 A is comparable to the original 6.9 A specification. DC resistance increases from 23 mOhm to 30 mOhm maximum, which may impact thermal performance in current-limited applications. The part is active in production with AEC-Q200 compliance and RoHS certification. Physical dimensions are slightly larger (4.95mm x 4.20mm versus 4.45mm x 4.06mm), requiring verification of board layout compatibility.

ETQ-P3M1R5KVP (Panasonic Electronic Components)

This substitute offers superior electrical performance with the lowest DC resistance at 13.2 mOhm maximum and the highest current rating at 8.1 A. The saturation current of 12 A provides significant margin above the original specification. The part utilizes drum core wirewound construction rather than molded design, and operates across an extended temperature range to 155°C. AEC-Q200 compliance and ROHS3 certification are provided. Physical dimensions are notably larger (5.50mm x 5.00mm x 3.00mm), requiring board layout assessment. This option is suitable for applications where thermal performance and current headroom are prioritized.

IHLP1616ABER1R5M11 (Vishay Dale)

This substitute maintains identical physical footprint (4.45mm x 4.06mm) and lower profile height (1.20mm) compared to the main part. Inductance and tolerance specifications are matched. However, the current rating of 3.25 A and saturation current of 3.25 A fall below the original part requirements of 4.9 A and 6.9 A respectively. DC resistance of 75 mOhm maximum is significantly higher than the original 23 mOhm. This part is suitable only for applications where current requirements are lower than the original design specification. ROHS3 compliance and REACH unaffected status are provided.

Recommendation Summary:

For direct replacement in existing designs, MPIA4020V2-1R5-R is the primary substitute, offering active production status and equivalent electrical performance. ETQ-P3M1R5KVP is recommended for new designs where improved thermal characteristics and current margin are beneficial. IHLP1616ABER1R5M11 is not recommended as a substitute for the original application due to insufficient current rating and saturation current specifications.

Frequently Asked Questions (FAQ)

Q: Can IHLP1616ABER1R5M11 be used as a direct replacement for MPIA4040R4-1R5-R?

A: No. While the IHLP1616ABER1R5M11 matches the inductance value and physical footprint, its current rating of 3.25 A and saturation current of 3.25 A are insufficient for applications requiring the original part's 4.9 A continuous current and 6.9 A saturation current specifications. This part is suitable only for lower-current applications.

Q: What is the impact of increased DC resistance in the MPIA4020V2-1R5-R substitute?

A: The DC resistance increases from 23 mOhm to 30 mOhm maximum, representing a 30% increase. This results in higher resistive losses and increased heat generation proportional to the square of the current. In applications operating near the 4.9 A rating, thermal performance will be degraded. Circuit thermal analysis is required to determine acceptability.

Q: Are all substitute parts AEC-Q200 qualified?

A: MPIA4020V2-1R5-R and ETQ-P3M1R5KVP carry AEC-Q200 compliance. IHLP1616ABER1R5M11 does not specify AEC-Q200 qualification. For automotive applications requiring AEC-Q200 compliance, only MPIA4020V2-1R5-R and ETQ-P3M1R5KVP are acceptable.

Q: What are the physical footprint differences between substitute parts?

A: MPIA4020V2-1R5-R measures 4.95mm x 4.20mm x 2.00mm, representing a 0.5mm increase in length and 0.14mm increase in width compared to the original. IHLP1616ABER1R5M11 maintains the original 4.45mm x 4.06mm footprint but reduces height to 1.20mm. ETQ-P3M1R5KVP is significantly larger at 5.50mm x 5.00mm x 3.00mm. Board layout verification is required for all substitutions.

Q: Which substitute offers the best thermal performance?

A: ETQ-P3M1R5KVP provides the lowest DC resistance at 13.2 mOhm maximum, resulting in the lowest resistive losses and best thermal performance. This part is recommended for applications where thermal management is critical.

Q: Are all substitute parts RoHS compliant?

A: MPIA4020V2-1R5-R is RoHS Compliant. ETQ-P3M1R5KVP and IHLP1616ABER1R5M11 are both ROHS3 Compliant. All three substitutes meet current RoHS requirements.

Q: What is the difference between molded and drum core wirewound construction?

A: MPIA4040R4-1R5-R, MPIA4020V2-1R5-R, and IHLP1616ABER1R5M11 use molded construction with metal composite cores. ETQ-P3M1R5KVP uses drum core wirewound construction. Wirewound designs typically offer lower DC resistance and higher current ratings but may exhibit different frequency response characteristics. Circuit performance validation is recommended when switching construction types.

Q: Can ETQ-P3M1R5KVP be used in space-constrained applications?

A: No. ETQ-P3M1R5KVP measures 5.50mm x 5.00mm x 3.00mm, making it significantly larger than the original part and other substitutes. Applications with strict height or footprint constraints should use MPIA4020V2-1R5-R or IHLP1616ABER1R5M11.
