MPIA2512V2-R68-R Equivalent & Substitute Parts

Part Overview

The MPIA2512V2-R68-R is a 680 nH shielded molded inductor manufactured by Eaton - Electronics Division. This surface mount component is designed for applications requiring fixed inductance with moderate current handling and low DC resistance characteristics. The part is classified as Active product status with full AEC-Q200 automotive qualification and RoHS compliance.

Substitute parts are identified when equivalent inductance values, package dimensions, current ratings, and thermal operating ranges align within acceptable engineering tolerances. The primary substitute identified maintains the same inductance specification and package footprint while offering alternative core material composition and performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPIA2512V2-R68-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 680 nH (±20% tolerance band)
• Package footprint: 1008 (2520 Metric) surface mount
• Shielding classification: Shielded
• Mounting type: Surface Mount

Secondary Compatibility Factors:

• Current rating capability (minimum 3.4 A required)
• DC resistance within acceptable operational limits
• Operating temperature range overlap with -40°C minimum
• AEC-Q200 automotive qualification
• RoHS compliance status

The identified substitute part SRP2512TMA-R68M meets all primary matching criteria and exceeds secondary compatibility requirements through higher current rating and lower DC resistance specifications.

Engineering Selection Recommendations

MPIA2512V2-R68-R (Eaton - Electronics Division):

• Active product status with established supply chain
• AEC-Q200 qualified for automotive applications
• RoHS Compliant certification
• Molded core construction with iron powder material
• Suitable for applications with current requirements up to 3.4 A

SRP2512TMA-R68M (Bourns Inc.):

• Active product status with established supply chain
• AEC-Q200 qualified for automotive applications
• ROHS3 Compliant certification (enhanced RoHS standard)
• Metal core construction with flat wire design
• Superior performance envelope: higher current rating (5.3 A), lower DC resistance (27.6 mOhm), extended temperature range (-55°C ~ 150°C)
• Higher self-resonant frequency (90 MHz vs 70 MHz)

Both parts satisfy identical inductance, package, and shielding requirements. Selection between these components depends on application-specific current demands, thermal environment, and core material compatibility with circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can SRP2512TMA-R68M directly replace MPIA2512V2-R68-R in existing designs?

A: Yes. Both components share identical inductance (680 nH ±20%), package footprint (1008/2520 Metric), and shielding classification. Physical dimensions are equivalent with negligible height difference (1.25mm vs 1.20mm). Both carry AEC-Q200 qualification and RoHS compliance. PCB layout and reflow profiles require no modification.

Q: What are the performance differences between these inductors?

A: The SRP2512TMA-R68M provides enhanced specifications: 5.3 A current rating versus 3.4 A, 27.6 mOhm DCR versus 35 mOhm, and -55°C to 150°C operating range versus -40°C to 125°C. Self-resonant frequency is 90 MHz compared to 70 MHz. These differences reflect metal core versus iron powder core construction and flat wire design implementation.

Q: Are there packaging or moisture sensitivity concerns?

A: Both components feature MSL 1 (Unlimited) moisture sensitivity classification, indicating no special moisture control requirements during storage or handling. Both are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: Which part should be selected for new designs?

A: Selection depends on application current requirements. For designs requiring 3.4 A or less, either part is acceptable. For applications approaching or exceeding 3.4 A, the SRP2512TMA-R68M provides design margin through higher current rating and lower DC resistance, reducing thermal dissipation and improving efficiency.

Q: Are there core material compatibility considerations?

A: The MPIA2512V2-R68-R uses iron powder core material; the SRP2512TMA-R68M uses metal core material. Both are shielded designs suitable for general RF and power applications. Core material selection affects frequency response characteristics and EMI performance. Verify compatibility with specific circuit filtering or impedance matching requirements.
