Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1269AS-H-3R3M=P2 is determined by the following critical parameters:

Inductance value must match at 3.3 µH with ±20% tolerance. Package and case designation must be identical: 1008 (2520 Metric) surface mount. Shielding type must be shielded to maintain electromagnetic isolation equivalent to the original design. Current rating of the substitute must equal or exceed 1.5 A to support the same load conditions. DC resistance must not exceed 228mOhm to preserve circuit performance characteristics. Operating temperature range must encompass or exceed the -40°C ~ 85°C specification of the main part.

The substitute part MPI2510V2-3R3-R from Eaton - Electronics Division meets these criteria with matching inductance, identical package geometry, shielded construction, and superior current rating (1.6 A) and lower DC resistance (170mOhm Max), while extending the operating temperature range to -40°C ~ 125°C.

Parameter Comparison

Engineering Selection Recommendations

Both the 1269AS-H-3R3M=P2 and MPI2510V2-3R3-R are Active product status components with full regulatory compliance. The Murata part carries RoHS3 certification, while the Eaton substitute carries RoHS certification. Both components maintain MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special storage or handling requirements.

The MPI2510V2-3R3-R substitute provides measurable performance advantages: 6.7% higher current rating (1.6 A vs. 1.5 A), 25.4% lower DC resistance (170mOhm vs. 228mOhm), and extended operating temperature range (125°C vs. 85°C maximum). These characteristics make the Eaton part suitable for applications requiring enhanced thermal performance or lower power dissipation. Both parts are electrically and mechanically interchangeable within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can MPI2510V2-3R3-R be used as a direct replacement for 1269AS-H-3R3M=P2?

A: Yes. Both parts share identical inductance (3.3 µH), tolerance (±20%), package designation (1008 / 2520 Metric), shielding type (Shielded), and mounting configuration (Surface Mount). The substitute meets or exceeds all critical electrical parameters of the original part.

Q: What are the differences in DC resistance between these parts?

A: The 1269AS-H-3R3M=P2 has a maximum DC resistance of 228mOhm, while the MPI2510V2-3R3-R has a maximum of 170mOhm. Lower DC resistance in the substitute results in reduced power dissipation and heat generation in the inductor.

Q: Are there temperature range considerations for substitution?

A: The 1269AS-H-3R3M=P2 operates from -40°C to 85°C, while the MPI2510V2-3R3-R operates from -40°C to 125°C. The substitute part supports a wider temperature envelope and is suitable for applications requiring extended thermal performance.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both components are rated MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Are there any compliance or certification differences?

A: The 1269AS-H-3R3M=P2 is RoHS3 compliant, while the MPI2510V2-3R3-R is RoHS compliant. Both meet environmental and regulatory requirements for their respective designations. Both carry ECCN EAR99 classification.

Q: Can the substitute handle the same current levels as the original part?

A: Yes. The MPI2510V2-3R3-R is rated for 1.6 A, which exceeds the 1.5 A rating of the 1269AS-H-3R3M=P2, providing additional current capacity margin.
