Substitute Part Grouping Explanation

Substitution of the MP2-330-R is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 33 µH with ±20% tolerance
• Operating temperature range: -40°C to 85°C minimum
• Inductance test frequency: 100 kHz
• Surface mount configuration with identical physical footprint

Mechanical Equivalence Criteria:

• Package dimensions: 0.295" L x 0.205" W (7.50mm x 5.20mm)
• Height - Seated (Max): 0.071" (1.80mm)
• Mounting type: Surface Mount

Acceptable Parameter Variations:

• Current rating may exceed the original specification (640 mA minimum required)
• DC resistance may be lower than the original specification (556 mOhm maximum acceptable)
• Core material may differ while maintaining electrical performance
• Product status may transition from obsolete to active

The MP2A-330-R qualifies as a direct substitute based on these criteria.

Engineering Selection Recommendations

The MP2A-330-R is a qualified substitute for the obsolete MP2-330-R based on the following engineering factors:

Product Status Consideration: The MP2A-330-R carries active product status from Eaton - Electronics Division, ensuring continued availability, technical support, and manufacturing consistency. The MP2-330-R is classified as obsolete, creating supply chain risk and limiting access to replacement inventory.

Electrical Performance: The MP2A-330-R exceeds the electrical requirements of the MP2-330-R. The substitute provides 790 mA current rating compared to the original 640 mA specification, and delivers lower DC resistance at 476 mOhm versus 556 mOhm maximum. Both components maintain identical inductance values of 33 µH with ±20% tolerance and operate across the same temperature range of -40°C to 85°C.

Mechanical Compatibility: The MP2A-330-R maintains identical physical dimensions and surface mount footprint as the MP2-330-R, enabling direct board-level substitution without layout modifications. Both components share the same package dimensions of 0.295" L x 0.205" W (7.50mm x 5.20mm) and seated height of 0.071" (1.80mm).

Compliance and Certifications: The MP2A-330-R is RoHS Compliant, meeting current environmental and regulatory requirements. Both components carry identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications and maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Core Material Difference: The MP2A-330-R utilizes Molybdenum Permalloy (MPP) core material compared to the ferrite core in the MP2-330-R. This material change results in improved electrical performance characteristics, including lower DC resistance and higher saturation current, while maintaining functional equivalence for the specified inductance value and operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the MP2A-330-R be used as a direct replacement for the MP2-330-R in existing designs?

A: Yes. The MP2A-330-R is a direct substitute for the MP2-330-R. Both components share identical inductance values (33 µH), tolerance specifications (±20%), operating temperature ranges (-40°C to 85°C), and physical footprints (0.295" L x 0.205" W, 0.071" max height). The substitute provides enhanced electrical performance with higher current rating (790 mA vs. 640 mA) and lower DC resistance (476 mOhm vs. 556 mOhm max), making it suitable for board-level substitution without design modifications.

Q: What are the key differences between the MP2-330-R and MP2A-330-R?

A: The primary differences are: (1) Product Status—MP2A-330-R is active while MP2-330-R is obsolete; (2) Core Material—MP2A-330-R uses Molybdenum Permalloy (MPP) versus ferrite in the original; (3) Current Rating—MP2A-330-R is rated for 790 mA compared to 640 mA; (4) DC Resistance—MP2A-330-R has 476 mOhm versus 556 mOhm maximum; (5) Series Designation—MP2A-330-R belongs to MICRO-PAC PLUS™ versus MICRO-PAC™; (6) Packaging—MP2A-330-R is supplied in Tape & Reel format; (7) RoHS Compliance—MP2A-330-R is RoHS Compliant.

Q: Are there any performance trade-offs when substituting the MP2-330-R with the MP2A-330-R?

A: No performance trade-offs exist. The MP2A-330-R meets or exceeds all electrical specifications of the MP2-330-R. The substitute delivers lower DC resistance and higher current rating, both of which represent performance improvements. The core material change from ferrite to Molybdenum Permalloy (MPP) results in these enhanced characteristics while maintaining the required 33 µH inductance value and ±20% tolerance.

Q: What is the impact of the different core materials on circuit performance?

A: The Molybdenum Permalloy (MPP) core in the MP2A-330-R provides superior electrical characteristics compared to the ferrite core in the MP2-330-R, including lower DC resistance and higher saturation current. Both materials maintain the specified inductance value of 33 µH and operate across the identical temperature range. The core material change does not affect functional performance for applications designed around the MP2-330-R specifications.

Q: Is the MP2A-330-R available in the same packaging format as the MP2-330-R?

A: The MP2A-330-R is supplied in Tape & Reel (TR) packaging, while the MP2-330-R packaging format is listed as nonstandard. Both components maintain identical physical dimensions and surface mount footprint, ensuring compatibility with standard pick-and-place assembly equipment. The Tape & Reel format of the MP2A-330-R provides advantages for automated manufacturing processes.

Q: Does the RoHS Compliance status of the MP2A-330-R affect compatibility with existing designs?

A: No. RoHS Compliance of the MP2A-330-R represents an enhancement over the MP2-330-R, ensuring compliance with current environmental and regulatory requirements. The RoHS status does not affect electrical or mechanical compatibility. Both components carry identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications.

Q: What inventory considerations should be evaluated when transitioning from MP2-330-R to MP2A-330-R?

A: The MP2A-330-R is actively manufactured by Eaton - Electronics Division with substantial inventory availability (4200 Pcs New Original In Stock reported). The MP2-330-R is classified as obsolete with limited remaining inventory (852 Pcs New Original In Stock reported). For new production and long-term supply chain stability, the MP2A-330-R is the recommended selection.
