Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPIA4040R3-R22-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 220 nH (exact match required)
• Shielding: Shielded construction
• Mounting type: Surface mount
• Operating temperature range: Minimum -55°C to 125°C coverage
• Inductance tolerance: ±20% or tighter
• Test frequency: 100 kHz

Secondary Compatibility Factors:

• Current rating: Minimum 8 A or higher
• DC resistance: Comparable performance (lower DCR preferred for reduced losses)
• Saturation current: Minimum 20 A or higher
• Moisture sensitivity: MSL 1 or equivalent
• Package footprint: Physical dimensions must accommodate board layout constraints

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

Parameter Comparison

Engineering Selection Recommendations

MPIA4020V2-R22-R (Eaton - Electronics Division)

This substitute is an active product from the same manufacturer as the original part. It maintains identical inductance, tolerance, and operating temperature specifications. The MPIA4020V2-R22-R provides higher current rating (13 A versus 8 A) and carries AEC-Q200 qualification matching the original. DC resistance is marginally higher at 6.6 mOhm maximum. Physical dimensions are slightly larger (4.95mm × 4.20mm versus 4.45mm × 4.06mm), requiring verification of board layout compatibility. RoHS compliance is confirmed. This option is recommended for applications where manufacturer continuity and automotive qualification are priorities.

IHLP1616ABERR22M01 (Vishay Dale)

This substitute is an active product offering identical inductance and tolerance specifications. Current rating of 8.5 A closely matches the original 8 A requirement. Physical footprint is identical to the original (4.45mm × 4.06mm), simplifying board layout integration. However, DC resistance is significantly higher at 12 mOhm maximum, resulting in increased power dissipation. Self-resonant frequency is higher at 183 MHz. ROHS3 compliance and REACH unaffected status are confirmed. This option is suitable for applications where footprint compatibility is critical and higher DC resistance is acceptable.

SRP7028A-R22Y (Bourns Inc.)

This substitute is an active product with significantly different electrical characteristics. It provides the lowest DC resistance at 2.8 mOhm maximum and the highest current rating at 23 A, making it suitable for high-current applications with minimal losses. Inductance tolerance is wider at ±30%. Operating temperature range extends to 150°C. Physical dimensions are substantially larger (7.30mm × 6.60mm with 3.00mm height), requiring board layout redesign. AEC-Q200 qualification, ROHS3 compliance, and REACH unaffected status are confirmed. This option is recommended for applications requiring superior thermal performance and current handling capability where space permits.

Frequently Asked Questions (FAQ)

Q: Can the MPIA4020V2-R22-R directly replace the MPIA4040R3-R22-R without circuit modifications?

A: The MPIA4020V2-R22-R maintains identical inductance (220 nH), tolerance (±20%), and operating temperature range (-55°C to 125°C). Both components are shielded surface mount inductors with AEC-Q200 qualification. Direct substitution is possible from an electrical standpoint. Physical dimensions differ slightly (4.95mm × 4.20mm versus 4.45mm × 4.06mm), requiring verification that the board layout accommodates the larger footprint.

Q: What is the significance of the higher DC resistance in the IHLP1616ABERR22M01?

A: The IHLP1616ABERR22M01 has a DC resistance of 12 mOhm maximum compared to 5.8 mOhm in the original part. This results in increased power dissipation according to the formula P = I²R. At the rated 8 A current, the IHLP1616ABERR22M01 dissipates approximately 768 mW compared to 371 mW for the original. Thermal management and circuit performance must be evaluated for applications sensitive to inductor losses.

Q: Why is the SRP7028A-R22Y significantly larger than the original part?

A: The SRP7028A-R22Y uses drum core wirewound construction with carbonyl powder core material, whereas the original MPIA4040R3-R22-R uses molded metal composite construction. The wirewound design enables superior current handling (23 A versus 8 A) and lower DC resistance (2.8 mOhm versus 5.8 mOhm), but requires larger physical dimensions (7.30mm × 6.60mm × 3.00mm). This size difference reflects the different core technology and performance characteristics.

Q: Are all three substitutes suitable for automotive applications?

A: The MPIA4020V2-R22-R and SRP7028A-R22Y both carry AEC-Q200 qualification, matching the original part's automotive rating. The IHLP1616ABERR22M01 does not specify AEC-Q200 qualification in the provided data. For applications requiring automotive-grade components, the MPIA4020V2-R22-R or SRP7028A-R22Y are appropriate selections.

Q: What is the impact of inductance tolerance differences on circuit performance?

A: The original part and MPIA4020V2-R22-R and IHLP1616ABERR22M01 all specify ±20% tolerance. The SRP7028A-R22Y specifies ±30% tolerance. Wider tolerance increases the range of possible inductance values in production units. For applications with tight frequency response or impedance matching requirements, the ±20% tolerance parts are preferred. The ±30% tolerance of the SRP7028A-R22Y may require circuit compensation or acceptance of wider performance variation.

Q: Can the SRP7028A-R22Y be used in space-constrained applications?

A: No. The SRP7028A-R22Y measures 7.30mm × 6.60mm × 3.00mm, significantly larger than the original MPIA4040R3-R22-R (4.45mm × 4.06mm × 1.80mm). This component requires substantial board area and clearance. For space-constrained designs, the MPIA4020V2-R22-R (4.95mm × 4.20mm × 2.00mm) or IHLP1616ABERR22M01 (4.45mm × 4.06mm × 1.20mm) are more suitable options.

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

A: The original MPIA4040R3-R22-R and MPIA4020V2-R22-R use molded metal composite construction, providing compact size and consistent performance. The SRP7028A-R22Y uses drum core wirewound construction with carbonyl powder core material, enabling higher current ratings and lower DC resistance at the cost of larger physical dimensions. Wirewound inductors typically exhibit lower Q factor but superior current handling and thermal characteristics.

Q: Are all substitutes RoHS compliant?

A: The MPIA4020V2-R22-R is RoHS Compliant. The IHLP1616ABERR22M01 and SRP7028A-R22Y are both ROHS3 Compliant. The original MPIA4040R3-R22-R does not specify RoHS status in the provided data. All three substitutes meet current RoHS requirements for new designs.
