MPLCG0630L3R3 Equivalent & Substitute Parts

Part Overview

The MPLCG0630L3R3 is a 3.3 µH shielded drum core wirewound inductor manufactured by KEMET, rated for 6.5 A continuous current with a maximum DC resistance of 30 mOhm. This component is designed for surface mount applications requiring low DCR and low loss characteristics in compact nonstandard packages. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across different manufacturer designs while preserving critical functional parameters for the target application.

Substitute Part Grouping Explanation

Substitute parts for the MPLCG0630L3R3 are qualified based on the following strict electrical and mechanical criteria:

Electrical Equivalence Requirements:

• Inductance value must be 3.3 µH at 100 kHz test frequency
• Current rating must equal or exceed 6.5 A continuous
• DC resistance must not exceed 30 mOhm maximum
• Shielding must be present to maintain EMI performance
• Tolerance must be ±20% or better

Mechanical Compatibility Requirements:

• Surface mount mounting type required
• Nonstandard package classification
• Physical dimensions must accommodate PCB layout constraints (height ≤ 3.00 mm seated maximum)
• Tape & Reel packaging for automated assembly

Regulatory & Compliance Requirements:

• RoHS3 compliance mandatory
• MSL 1 (Unlimited) moisture sensitivity level
• Active product status preferred for supply continuity

The ASPI-0630HI-3R3M-T15 from Abracon LLC meets all substitution criteria through equivalent inductance, superior current rating (6.8 A vs. 6.5 A), matching DCR specification, and identical shielding and compliance certifications.

Engineering Selection Recommendations

Primary Part: MPLCG0630L3R3 (KEMET)

Selection criteria: Use as primary choice when KEMET supply chain availability is confirmed and cost is not a constraint. Drum core wirewound construction provides established performance in low-loss applications. Active product status ensures long-term availability.

Substitute Part: ASPI-0630HI-3R3M-T15 (Abracon LLC)

Selection criteria: Use as direct substitute when:

• KEMET MPLCG0630L3R3 supply is unavailable or lead times exceed project requirements
• Extended low-temperature operation below -40°C is required (rated to -55°C)
• Higher saturation current margin is beneficial for transient protection (13.5 A vs. 6.3 A)
• Molded inductor construction is acceptable for the application

Both parts maintain identical electrical performance at rated operating conditions, equivalent mechanical fit within nonstandard package constraints, and full regulatory compliance (RoHS3, REACH Unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can ASPI-0630HI-3R3M-T15 be used as a direct replacement for MPLCG0630L3R3 without circuit redesign?

A: Yes. Both inductors provide 3.3 µH inductance at 100 kHz with ±20% tolerance, 30 mOhm maximum DCR, and shielded construction. The ASPI part exceeds minimum current rating (6.8 A vs. 6.5 A required) and saturation current specification. Physical dimensions are compatible within nonstandard package constraints (height identical at 3.00 mm maximum). No circuit modifications are required.

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

A: MPLCG0630L3R3 uses drum core wirewound construction with metal composite core material. ASPI-0630HI-3R3M-T15 uses molded construction with carbonyl powder core material. Both designs achieve equivalent inductance, DCR, and shielding performance. Molded construction typically offers improved mechanical robustness and thermal stability. Selection depends on application-specific environmental and vibration requirements.

Q: Are there temperature range differences that affect substitution?

A: ASPI-0630HI-3R3M-T15 operates from -55°C to 125°C, extending the lower temperature limit by 15°C compared to MPLCG0630L3R3 (-40°C to 125°C). For applications operating above -40°C, both parts are equivalent. For applications requiring operation below -40°C, the Abracon part provides extended capability.

Q: Do physical dimension differences affect PCB layout?

A: Dimensions are compatible. MPLCG0630L3R3 measures 7.50mm L x 6.70mm W x 3.00mm H. ASPI-0630HI-3R3M-T15 measures 7.20mm L x 6.65mm W x 3.00mm H. The Abracon part is slightly smaller in length and width while maintaining identical height. Both fit within nonstandard package footprints. Verify specific PCB land pattern compatibility with component datasheets.

Q: What compliance certifications apply to both parts?

A: Both MPLCG0630L3R3 and ASPI-0630HI-3R3M-T15 are RoHS3 compliant, REACH Unaffected, and classified as EAR99 for export control. MSL rating is 1 (Unlimited) for both parts, indicating no moisture sensitivity restrictions during storage or handling.

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable based on supplier availability and cost. KEMET MPLCG0630L3R3 offers established market presence. Abracon ASPI-0630HI-3R3M-T15 provides superior saturation current margin and extended temperature range at potentially lower cost. Evaluate supplier lead times and inventory levels for project timeline requirements.
