MP2-R47-R Equivalent & Substitute Parts Reference

Part Overview

The MP2-R47-R is a 470 nH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division, part of the MICRO-PAC™ series. This component is rated for 2.02 A continuous current with a maximum DC resistance of 75 mOhm and operates across the temperature range of -40°C to 85°C. The part is currently classified as obsolete, making identification of suitable equivalent components essential for ongoing design support and production continuity. Substitute parts must maintain the same inductance value and core electrical characteristics while accommodating available alternatives from active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP2-R47-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 470 nH (±20% tolerance)
• Mounting type: Surface Mount
• Package footprint compatibility: 7.50 mm × 5.20 mm base dimensions
• Operating temperature range: minimum -40°C to 85°C coverage
• Current handling capability: rated for ≥2.02 A continuous operation

Secondary Compatibility Factors:

• DC resistance: lower values preferred (≤75 mOhm reduces thermal losses)
• Saturation current: ≥3.4 A ensures margin above rated current
• Core material and shielding: may vary based on application EMI requirements
• Product status: active parts preferred for long-term availability

The two substitute parts identified below meet the primary inductance and mounting criteria while offering different trade-offs in current capacity, DCR performance, and core technology.

Engineering Selection Recommendations

MPLCG0630LR47 (KEMET) — Preferred Substitute

The MPLCG0630LR47 is the primary recommended substitute for the obsolete MP2-R47-R. Both components share the identical 470 nH inductance specification and ±20% tolerance. The KEMET part offers superior electrical performance with a DC resistance of 5 mOhm (compared to 75 mOhm maximum in the original), resulting in significantly lower resistive losses and reduced thermal dissipation. The current rating of 15.8 A provides substantial margin above the original 2.02 A requirement, ensuring robust performance under transient conditions. The shielded design offers improved EMI containment compared to the unshielded original, beneficial in noise-sensitive applications.

The MPLCG0630LR47 is an active product with ROHS3 compliance and extended operating temperature range (-40°C to 125°C), supporting long-term design continuity. The primary mechanical consideration is the increased height (3.00 mm versus 1.80 mm) and slightly wider footprint (6.70 mm versus 5.20 mm width), which must be verified against PCB layout constraints.

MP2A-470-R (Eaton) — Limited Compatibility

The MP2A-470-R shares the same manufacturer and maintains identical package dimensions and height as the original MP2-R47-R. However, this part is fundamentally incompatible due to its inductance value of 47 µH, which is 100 times larger than the required 470 nH specification. Additionally, the current rating of 640 mA falls below the original 2.02 A requirement, and the DC resistance of 727 mOhm is significantly higher. This part should not be used as a substitute for the MP2-R47-R in any application requiring the original 470 nH inductance.

Selection Criteria Summary:

• For direct electrical replacement with improved performance: MPLCG0630LR47
• For applications with strict height constraints: Verify MPLCG0630LR47 clearance; no equivalent height-matched alternative identified
• For RoHS compliance: Both active substitutes meet regulatory requirements
• For extended temperature operation: MPLCG0630LR47 supports -40°C to 125°C

Frequently Asked Questions (FAQ)

Q: Can MP2A-470-R be used as a substitute for MP2-R47-R?

A: No. The MP2A-470-R has an inductance of 47 µH, which is 100 times larger than the required 470 nH. This part is electrically incompatible and will not function correctly in circuits designed for 470 nH inductance. The current rating of 640 mA also falls below the original 2.02 A specification.

Q: What are the main differences between MPLCG0630LR47 and the original MP2-R47-R?

A: Both parts share the same 470 nH inductance and ±20% tolerance. Key differences include: (1) MPLCG0630LR47 has shielding versus unshielded original; (2) DC resistance is 5 mOhm versus 75 mOhm, reducing losses; (3) current rating is 15.8 A versus 2.02 A, providing greater margin; (4) height is 3.00 mm versus 1.80 mm; (5) width is 6.70 mm versus 5.20 mm; (6) operating temperature extends to 125°C versus 85°C maximum.

Q: Will the MPLCG0630LR47 fit in the same PCB footprint as the MP2-R47-R?

A: The base footprint dimensions differ. The MPLCG0630LR47 is 7.50 mm × 6.70 mm compared to 7.50 mm × 5.20 mm for the original. The length is identical, but the width is 1.50 mm wider. PCB layout must be verified to confirm clearance. The height difference (3.00 mm versus 1.80 mm) must also be checked against component stacking and enclosure constraints.

Q: Is the MPLCG0630LR47 RoHS compliant?

A: Yes. The MPLCG0630LR47 carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. The original MP2-R47-R RoHS status was not specified in available documentation.

Q: Why does the MPLCG0630LR47 have a much higher current rating than the original?

A: The MPLCG0630LR47 uses a metal composite core material with superior saturation characteristics compared to the ferrite core in the MP2-R47-R. This enables higher current handling while maintaining the same inductance value. The 15.8 A rating provides design margin and reduces the risk of saturation-induced inductance collapse under transient current spikes.

Q: Can I use MPLCG0630LR47 in applications requiring the unshielded design of the original?

A: The shielded design of MPLCG0630LR47 will not negatively impact most applications. Shielding reduces radiated EMI and improves noise immunity. If the original unshielded design was specifically required to allow magnetic field coupling to adjacent components, the shielded substitute may alter circuit behavior and should be evaluated in the target application.

Q: What is the packaging format for substitute parts?

A: Both active substitutes (MP2A-470-R and MPLCG0630LR47) are supplied in Tape & Reel (TR) format, standard for surface mount production. The original MP2-R47-R packaging format was not specified in available documentation.

Q: Are there any other 470 nH inductors available as alternatives?

A: Based on the provided substitute list, MPLCG0630LR47 is the only electrically compatible 470 nH alternative identified. MP2A-470-R is listed as a substitute in the original part documentation but is not electrically equivalent due to its 47 µH inductance value.
