Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP2-220-R are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters for Substitution:

• Inductance value: 22 µH (exact match required)
• Inductance tolerance: ±20% (matching specification)
• Mounting type: Surface Mount (identical)
• Operating temperature range: -40°C to 85°C (minimum requirement)
• Inductance test frequency: 100 kHz (measurement standard)
• Physical footprint compatibility: 7.50 × 5.20 mm nominal dimensions

Secondary Parameters Evaluated:

• Current rating: Substitute must meet or exceed 800 mA minimum
• DC resistance: Lower values preferred for reduced losses
• Core material: Ferrite or equivalent magnetic material acceptable
• Shielding: Unshielded configuration maintained

Two substitute parts meet these criteria: MP2A-220-R (Eaton Electronics Division, MICRO-PAC PLUS™ series) and AX97-10220 (Triad Magnetics, AX97 series). Both maintain the 22 µH inductance specification with ±20% tolerance and surface mount configuration suitable for direct replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

MP2A-220-R Selection Criteria:

The MP2A-220-R represents the primary substitute option for the obsolete MP2-220-R. This part maintains identical physical dimensions (7.50 × 5.20 × 1.80 mm), inductance specification (22 µH ±20%), and operating temperature range (-40°C to 85°C). The MP2A-220-R offers superior electrical performance with increased current rating (980 mA versus 800 mA) and reduced DC resistance (311 mOhm versus 360 mOhm maximum). The part is manufactured by the same supplier (Eaton Electronics Division) and is classified as active product status, ensuring long-term availability. RoHS compliance certification is provided. The core material differs (Molybdenum Permalloy versus Ferrite), which may affect frequency response characteristics but maintains functional equivalence at the 100 kHz test frequency. Tape & Reel packaging is standard for production volumes.

AX97-10220 Selection Criteria:

The AX97-10220 from Triad Magnetics serves as an alternative substitute when MP2A-220-R availability is constrained. This part maintains the 22 µH inductance specification with ±20% tolerance and identical operating temperature range. The current rating (700 mA) falls below the original MP2-220-R specification (800 mA), requiring circuit-level verification for applications approaching maximum current limits. DC resistance is higher (430 mOhm maximum) compared to both the original part and MP2A-220-R alternative. Physical dimensions differ slightly (7.30 × 4.78 × 4.78 mm), with increased height (3.23 mm versus 1.80 mm), necessitating PCB layout verification for space-constrained applications. The part is active product status with ROHS3 compliance. Ferrite core material matches the original MP2-220-R specification.

Recommendation Priority:

1. Primary: MP2A-220-R for direct replacement with improved electrical performance and identical form factor
2. Secondary: AX97-10220 when primary substitute is unavailable, with circuit verification for current and height constraints

Frequently Asked Questions (FAQ)

Q: Can MP2A-220-R directly replace MP2-220-R without circuit modification?

A: Yes. The MP2A-220-R maintains identical inductance (22 µH ±20%), physical dimensions (7.50 × 5.20 × 1.80 mm), operating temperature range (-40°C to 85°C), and mounting type (surface mount). The increased current rating (980 mA) and reduced DC resistance (311 mOhm) provide improved performance margins. Core material differs (Molybdenum Permalloy versus Ferrite), but both materials satisfy the 100 kHz inductance test frequency specification.

Q: What are the limitations of AX97-10220 as a substitute?

A: The AX97-10220 has two primary constraints: (1) Current rating of 700 mA is below the original 800 mA specification, requiring verification that circuit peak currents do not exceed this limit; (2) Physical height is 3.23 mm compared to 1.80 mm for the original part, potentially conflicting with PCB clearance requirements in space-constrained designs. DC resistance is also higher (430 mOhm maximum).

Q: Are there packaging differences between substitute parts?

A: Yes. The MP2A-220-R is supplied in Tape & Reel (TR) packaging, standard for production assembly. The AX97-10220 is supplied in Bulk packaging. The original MP2-220-R packaging specification is not provided in the reference data.

Q: Do substitute parts have different compliance certifications?

A: Both substitute parts carry RoHS compliance certifications. MP2A-220-R is RoHS Compliant. AX97-10220 is ROHS3 Compliant. Both parts carry identical ECCN (EAR99) and HTSUS classifications as the original part.

Q: What is the impact of core material differences?

A: The MP2-220-R uses Ferrite core material. The MP2A-220-R uses Molybdenum Permalloy (MPP) core material, which typically provides lower core losses and better temperature stability. The AX97-10220 maintains Ferrite core material matching the original. Both substitute options maintain the 22 µH inductance specification at 100 kHz test frequency. Core material selection should be verified against specific frequency response and thermal performance requirements in the application circuit.

Q: Is the ±20% inductance tolerance maintained across all parts?

A: Yes. The MP2-220-R, MP2A-220-R, and AX97-10220 all specify ±20% inductance tolerance, ensuring consistent circuit performance across the substitution options.
