1269AS-H-1R0M=P2 Equivalent & Substitute Parts

Part Overview

The 1269AS-H-1R0M=P2 is a 1 µH shielded drum core wirewound inductor manufactured by Murata Electronics, rated for 2.7 A continuous current with a maximum DC resistance of 78 mOhm. This surface mount component in 1008 (2520 Metric) package is designed for applications requiring compact, shielded inductance in the microhenry range. The part maintains active product status and is RoHS3 compliant. Substitute parts are identified when equivalent inductance, current rating, package compatibility, and operating temperature range requirements can be met by alternative manufacturers while maintaining functional performance in the target application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1269AS-H-1R0M=P2 is determined by the following critical parameters:

Inductance value must be 1 µH with ±20% tolerance to maintain circuit performance. Package and case designation must be 1008 (2520 Metric) to ensure mechanical and electrical compatibility with PCB layouts. Shielding requirement must be maintained to prevent electromagnetic interference. Current rating must meet or exceed 2.7 A to handle the design load without saturation or thermal stress. DC resistance should not exceed 78 mOhm to maintain efficiency and minimize power loss. Operating temperature range must encompass the application environment, with -40°C ~ 85°C as the baseline requirement. Surface mount mounting type is mandatory for automated assembly compatibility.

The substitute part MPI2510V2-1R0-R from Eaton - Electronics Division meets these criteria with matching inductance, package, shielding, and mounting type, while providing improved current rating (3.1 A) and lower DC resistance (52 mOhm Max).

Parameter Comparison

Engineering Selection Recommendations

Both the 1269AS-H-1R0M=P2 and MPI2510V2-1R0-R are active products with current manufacturing status. The Murata part carries RoHS3 compliance, while the Eaton substitute carries RoHS compliance. Both parts are classified under ECCN EAR99 for export control purposes.

The MPI2510V2-1R0-R provides performance advantages including higher current saturation rating (4.3 A), lower DC resistance (52 mOhm versus 78 mOhm), and extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C). These characteristics make the Eaton part suitable for applications requiring improved thermal margin or higher current headroom while maintaining identical inductance and package specifications.

Selection between these parts should be based on application-specific requirements for current capacity, thermal environment, and compliance certifications. Both parts are electrically and mechanically interchangeable within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can MPI2510V2-1R0-R replace 1269AS-H-1R0M=P2 in existing designs?

A: Yes. Both parts share identical inductance (1 µH), tolerance (±20%), package (1008 / 2520 Metric), shielding, and mounting type. The Eaton part provides superior current rating and lower DC resistance, making it a direct functional substitute.

Q: What is the significance of the lower DC resistance in the Eaton part?

A: Lower DC resistance (52 mOhm versus 78 mOhm) reduces resistive losses and heat generation during operation. This improves efficiency and allows the inductor to handle current loads with less thermal stress.

Q: Does the extended operating temperature range of the Eaton part affect compatibility?

A: No. The extended range (-40°C ~ 125°C versus -40°C ~ 85°C) provides additional thermal margin but does not affect compatibility. Applications operating within the original -40°C ~ 85°C range will function identically with either part.

Q: Are there any compliance differences between these parts?

A: The Murata part is RoHS3 compliant, while the Eaton part is RoHS compliant. Both meet regulatory requirements for their respective markets. Verify compliance requirements for your specific application and region.

Q: Is the package dimension identical between both parts?

A: Yes. Both parts use the 1008 (2520 Metric) package with matching length (0.098" / 2.50 mm) and width (0.079" / 2.00 mm). Height differs slightly (1.00 mm versus 1.05 mm), which is negligible for most PCB layouts.

Q: What does the ±20% inductance tolerance mean for circuit design?

A: The ±20% tolerance indicates that actual inductance values may range from 0.8 µH to 1.2 µH. Circuit designs must account for this variation to ensure performance across the tolerance band.
