Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP2-6R8-R is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 6.8 µH (fixed requirement)
• Inductance tolerance: ±20% (fixed requirement)
• Operating temperature range: -40°C to 85°C (minimum requirement)
• Mounting type: Surface Mount (fixed requirement)
• Physical footprint compatibility: 7.50 mm × 5.20 mm length and width, 1.80 mm maximum seated height
• Moisture Sensitivity Level: 1 (Unlimited) or equivalent

Secondary Electrical Parameters (Application-Dependent):

• Current rating must equal or exceed 1.06 A
• DC resistance and saturation current characteristics must be compatible with circuit requirements
• Shielding configuration (unshielded) must match application needs

The substitute parts MP2A-6R8-R and 83682C meet the primary substitution criteria. Both maintain the 6.8 µH inductance value, ±20% tolerance, surface mount configuration, identical physical dimensions, and operating temperature range. Both are classified as active products with current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

MP2A-6R8-R (Eaton - Electronics Division)

The MP2A-6R8-R is the primary substitute for the obsolete MP2-6R8-R. This component is manufactured by the same supplier and represents an active product within the MICRO-PAC PLUS™ series. It maintains identical inductance, tolerance, physical dimensions, and operating temperature specifications. The MP2A-6R8-R provides improved electrical performance with higher current rating (1.49 A versus 1.06 A), lower DC resistance (136 mOhm versus 202 mOhm maximum), and higher saturation current (1.53 A versus 800 mA). The core material differs (Molybdenum Permalloy versus Ferrite), which may affect frequency response characteristics but does not impact substitution validity for the specified electrical parameters. The part is RoHS Compliant and available in Tape & Reel packaging.

83682C (Murata Power Solutions Inc.)

The 83682C is an alternative substitute manufactured by Murata Power Solutions Inc. within the 8300 series. This component maintains the 6.8 µH inductance, ±20% tolerance, surface mount configuration, and identical operating temperature range. The physical dimensions differ slightly in length (7.80 mm versus 7.50 mm), while width and height remain identical. The 83682C is rated for 950 mA continuous current, which is below the original 1.06 A specification but may be acceptable for applications with reduced current requirements. DC resistance is 150 mOhm maximum, representing an improvement over the original 202 mOhm specification. The part is ROHS3 Compliant and REACH Unaffected, available in Tape & Reel packaging.

Selection Criteria:

• For direct replacement with improved performance and same-supplier continuity: MP2A-6R8-R
• For alternative sourcing with acceptable current derating: 83682C (verify application current requirements do not exceed 950 mA)
• For applications requiring maximum current capacity: MP2A-6R8-R (1.49 A rating)
• For applications with tight PCB space constraints: MP2-6R8-R or MP2A-6R8-R (7.50 mm length) over 83682C (7.80 mm length)

Frequently Asked Questions (FAQ)

Q: Can MP2A-6R8-R directly replace MP2-6R8-R in existing designs?

A: Yes. The MP2A-6R8-R maintains identical inductance (6.8 µH), tolerance (±20%), operating temperature range (-40°C to 85°C), surface mount configuration, and physical footprint (7.50 × 5.20 × 1.80 mm). The improved electrical specifications (higher current rating, lower DC resistance) provide enhanced performance margins. No circuit redesign is required.

Q: What is the difference between the core materials in MP2-6R8-R and MP2A-6R8-R?

A: The MP2-6R8-R uses a Ferrite core, while the MP2A-6R8-R uses a Molybdenum Permalloy (MPP) core. Both materials support the specified 6.8 µH inductance and operating temperature range. The core material difference may affect frequency response and Q factor characteristics but does not impact the primary substitution parameters for DC and low-frequency AC applications.

Q: Is 83682C suitable for all applications using MP2-6R8-R?

A: The 83682C is suitable for applications where the continuous current requirement does not exceed 950 mA. The original MP2-6R8-R is rated for 1.06 A. Applications requiring current above 950 mA must use MP2A-6R8-R (1.49 A rating). Verify application current specifications before selecting 83682C.

Q: What is the physical footprint difference between 83682C and the original part?

A: The 83682C length is 7.80 mm compared to 7.50 mm for MP2-6R8-R and MP2A-6R8-R. The width (5.20 mm) and seated height (1.80 mm) are identical. For PCB layouts with tight horizontal spacing constraints, MP2A-6R8-R is preferred. For applications with adequate board space, 83682C is compatible.

Q: Are both substitute parts RoHS compliant?

A: Yes. MP2A-6R8-R is RoHS Compliant. 83682C is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What is the inventory status of these substitute parts?

A: MP2A-6R8-R: 987 pieces new original in stock. 83682C: 1,107 pieces new original in stock. Both substitutes are actively manufactured and readily available.

Q: Can I use MP2A-6R8-R in applications originally designed for MP2-6R8-R without testing?

A: The MP2A-6R8-R meets all primary substitution criteria and provides improved electrical performance. However, applications with specific frequency response or Q factor requirements should verify that the Molybdenum Permalloy core material characteristics are compatible with circuit performance expectations.
