Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPIA4040R2-R47-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 470 nH with ±20% tolerance
• Shielding requirement: Shielded construction
• Mounting type: Surface Mount
• Operating temperature range: Minimum -55°C to 125°C coverage
• Inductance test frequency: 100 kHz

Secondary Compatibility Factors:

• Current rating: Substitute must support minimum 6.4 A continuous operation
• DC resistance: Electrical performance impact; lower DCR values are acceptable
• Moisture sensitivity: MSL 1 rating required
• Physical dimensions: Package footprint compatibility with board layout

All identified substitutes meet the primary matching criteria. Variations in current saturation ratings, DC resistance specifications, and physical dimensions are documented to enable informed selection based on specific application requirements.

Engineering Selection Recommendations

MPIA4015V2-R47-R (Eaton - Electronics Division)

This substitute is the primary recommendation for direct replacement. It maintains manufacturer continuity with Eaton - Electronics Division, carries active product status, and holds AEC-Q200 qualification matching the original part. The current rating of 7.8 A exceeds the 6.4 A requirement, providing operational margin. DC resistance of 14 mOhm Max is comparable to the original 13 mOhm specification. The part is available in Tape & Reel packaging with 838 units in stock.

SRP5015TA-R47M (Bourns Inc.)

This substitute offers the highest current rating at 8 A with DC resistance of 13.8 mOhm Max, closely matching the original electrical characteristics. The part holds AEC-Q200 qualification and active product status. Operating temperature range extends to 150°C, providing additional thermal margin. Physical dimensions are slightly larger (5.70mm x 5.20mm versus 4.45mm x 4.06mm), requiring board layout verification. Inventory availability is 4243 units.

IHLP1616ABERR47M01 (Vishay Dale)

This substitute meets all primary matching criteria with active product status and extensive inventory (31707 units). However, the current rating of 5 A falls below the 6.4 A requirement and does not carry AEC-Q200 qualification. DC resistance of 22 mOhm Max is elevated relative to the original specification. This option is suitable only for applications where current requirements can be reduced or where AEC-Q200 qualification is not mandatory.

Frequently Asked Questions (FAQ)

Q: Can MPIA4015V2-R47-R directly replace MPIA4040R2-R47-R without circuit modification?

A: Yes. Both parts share identical inductance (470 nH ±20%), shielding, operating temperature range, and AEC-Q200 qualification. The MPIA4015V2-R47-R provides higher current capacity (7.8 A versus 6.4 A) and comparable DC resistance, making it a direct functional substitute. Verify board layout compatibility with the 2-SMD, J-Lead package configuration.

Q: What is the impact of higher DC resistance in the IHLP1616ABERR47M01 substitute?

A: The IHLP1616ABERR47M01 exhibits 22 mOhm Max DCR compared to 13 mOhm in the original part. This 69% increase in resistance results in higher power dissipation at rated current levels. For the 6.4 A operating point, power loss increases from approximately 0.53 mW to 0.90 mW. This substitute is appropriate only when thermal budget permits the additional dissipation or when operating current is reduced.

Q: Does the SRP5015TA-R47M larger package size affect PCB layout?

A: The SRP5015TA-R47M measures 5.70mm x 5.20mm compared to 4.45mm x 4.06mm for the original part. This represents a 28% increase in footprint area. Board layout verification is required to confirm pad spacing compatibility and clearance from adjacent components. Height remains consistent at 1.50mm maximum.

Q: Which substitute is recommended for automotive applications?

A: Both MPIA4015V2-R47-R and SRP5015TA-R47M carry AEC-Q200 qualification, meeting automotive reliability standards. MPIA4015V2-R47-R maintains manufacturer continuity with Eaton and is the preferred selection. SRP5015TA-R47M is an acceptable alternative with extended temperature range to 150°C.

Q: Is the IHLP1616ABERR47M01 suitable for high-reliability applications?

A: The IHLP1616ABERR47M01 does not carry AEC-Q200 qualification and exhibits current rating below the original specification. It is not recommended for high-reliability or automotive applications. Use is limited to commercial-grade applications where current requirements are reduced and qualification standards are not mandated.

Q: What is the significance of the ±20% inductance tolerance across all substitutes?

A: All parts, including the original and substitutes, share ±20% inductance tolerance at 100 kHz test frequency. This tolerance is consistent across the product group and does not differentiate substitution suitability. Circuit design must account for this tolerance range in all cases.
