MP2-100-R Equivalent & Substitute Parts Reference

Part Overview

The MP2-100-R is a 10 µH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division, part of the MICRO-PAC™ series. This component is rated for 980 mA continuous current with a maximum DC resistance of 240 mOhm and operates across the temperature range of -40°C to 85°C. The MP2-100-R is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP2-100-R are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for valid substitution:

Critical Matching Parameters:

• Inductance value: 10 µH
• Inductance tolerance: ±20%
• Operating temperature range: -40°C to 85°C
• Mounting type: Surface Mount
• Physical footprint: 7.50mm L x 5.20mm W x 1.80mm H maximum seated height
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 980 mA
• DC resistance: Substitute must not exceed 240 mOhm
• Core material: May differ (ferrite, molybdenum permalloy, or toroidal designs acceptable)
• Shielding: Unshielded configuration maintained

Two substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

MP2A-100-R (Eaton - Electronics Division)

The MP2A-100-R is the primary substitute for the obsolete MP2-100-R. Both components are manufactured by Eaton and share identical inductance, tolerance, operating temperature range, and physical footprint. The MP2A-100-R offers superior electrical performance with a current rating of 1.29 A (compared to 980 mA) and lower DC resistance of 179 mOhm (compared to 240 mOhm maximum). The MP2A-100-R uses molybdenum permalloy core material instead of ferrite, which may provide improved frequency response characteristics. This part is currently in active production status and is available in Tape & Reel packaging with RoHS compliance certification. The MP2A-100-R is suitable for direct replacement in applications where the original MP2-100-R was specified.

83103C (Murata Power Solutions)

The 83103C is an alternative substitute manufactured by Murata Power Solutions. This component maintains the same 10 µH inductance, ±20% tolerance, and operating temperature range as the MP2-100-R. The 83103C uses a toroidal core design instead of drum core construction. Physical dimensions are nearly identical, with a length of 7.80mm (compared to 7.50mm) and the same width and height specifications. The current rating of 750 mA is lower than the MP2-100-R specification of 980 mA, and DC resistance is 185 mOhm maximum. The 83103C is currently in active production with ROHS3 compliance and REACH unaffected status. This part is suitable for applications where current requirements do not exceed 750 mA and where toroidal core characteristics are acceptable.

Selection Criteria:

For applications requiring the full 980 mA current rating and improved electrical performance, the MP2A-100-R is the recommended substitute. For applications with lower current requirements (≤750 mA) and where toroidal core design is compatible with circuit requirements, the 83103C provides an alternative from a different manufacturer with active production status.

Frequently Asked Questions (FAQ)

Q: Can the MP2A-100-R be used as a direct replacement for the MP2-100-R?

A: Yes. Both components share identical inductance (10 µH), tolerance (±20%), operating temperature range (-40°C to 85°C), physical footprint (7.50mm x 5.20mm x 1.80mm), and mounting type (Surface Mount). The MP2A-100-R provides equal or superior electrical performance with higher current rating (1.29 A vs. 980 mA) and lower DC resistance (179 mOhm vs. 240 mOhm maximum).

Q: What is the difference between the MP2-100-R and MP2A-100-R core materials?

A: The MP2-100-R uses ferrite core material, while the MP2A-100-R uses molybdenum permalloy (MPP) core material. Both are unshielded drum core wirewound designs. The core material difference may affect frequency response and saturation characteristics, but both maintain the same inductance value and tolerance specification.

Q: Can the 83103C be used in place of the MP2-100-R?

A: The 83103C is compatible with the MP2-100-R for applications where the current requirement does not exceed 750 mA. The 83103C has a lower current rating (750 mA) compared to the MP2-100-R (980 mA). Physical dimensions are nearly identical with a 0.30mm difference in length (7.80mm vs. 7.50mm). The 83103C uses toroidal core construction instead of drum core design. Verify that circuit current requirements and toroidal core characteristics are acceptable before substitution.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating?

A: All three components (MP2-100-R, MP2A-100-R, and 83103C) carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture control requirements. This parameter is identical across all parts and does not affect substitution decisions.

Q: Are there packaging differences between the substitute parts?

A: The MP2-100-R packaging is listed as nonstandard with no specified supplier device package. The MP2A-100-R and 83103C are both supplied in Tape & Reel (TR) packaging, which is standard for surface mount components. This difference does not affect electrical compatibility but may affect procurement and assembly processes.

Q: What compliance certifications apply to these parts?

A: The MP2-100-R compliance status is not specified. The MP2A-100-R is RoHS Compliant. The 83103C is ROHS3 Compliant and REACH Unaffected. All three components share identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications. Verify compliance requirements for your specific application before final part selection.

Q: How do saturation current ratings affect substitution?

A: The MP2-100-R has saturation current (Isat) of 680 mA, the MP2A-100-R has 1.42 A, and the 83103C has 1.04 A. Saturation current represents the point at which inductance begins to degrade under high current conditions. Higher saturation current provides greater margin before performance degradation. For applications operating near the 980 mA rating of the MP2-100-R, the MP2A-100-R with 1.42 A saturation current provides superior headroom.
