Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DEM8045Z-150M=P3 are identified through strict alignment of the following critical parameters:

Primary Matching Criteria:

• Inductance value of 15 µH
• Inductance tolerance of ±20%
• Ferrite core material
• Surface mount configuration
• Nonstandard package classification
• AEC-Q200 qualification
• ROHS3 compliance

Secondary Compatibility Factors:

• Current rating capability (minimum 2.4 A acceptable for applications not requiring full 3.5 A capacity)
• DC resistance within acceptable operating margins
• Operating temperature range overlap (-40°C minimum and 125°C maximum coverage)
• Wirewound construction type

The SRN8040HA-150M from Bourns Inc. meets all primary matching criteria and maintains functional equivalence for applications where the current rating of 2.4 A is sufficient. The semi-shielded configuration provides comparable electromagnetic isolation characteristics for most circuit topologies.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: DEM8045Z-150M=P3

The DEM8045Z-150M=P3 is the specified component for applications requiring the full 3.5 A current rating with fully shielded electromagnetic containment. This part maintains active production status with confirmed inventory of 1131 units. AEC-Q200 qualification and ROHS3 compliance certify suitability for automotive and regulated industrial environments.

Substitute Part: SRN8040HA-150M

The SRN8040HA-150M from Bourns Inc. serves as a functional equivalent for circuit designs where the continuous current requirement does not exceed 2.4 A. This part is also AEC-Q200 qualified and ROHS3 compliant, ensuring regulatory and quality standard alignment. The semi-shielded configuration provides adequate electromagnetic isolation for most applications, with the trade-off of slightly elevated DC resistance (86 mOhm vs. 52.8 mOhm). The extended operating temperature range to 150°C offers additional thermal margin in high-temperature environments. Inventory availability of 1689 units supports supply chain continuity.

Selection Criteria:

Choose the DEM8045Z-150M=P3 when circuit design requires continuous current operation at or above 2.5 A, or when full shielding is mandatory for electromagnetic compatibility. Select the SRN8040HA-150M when current requirements remain below 2.4 A and semi-shielded performance is acceptable, particularly in applications benefiting from the extended temperature rating.

Frequently Asked Questions (FAQ)

Q: Can the SRN8040HA-150M directly replace the DEM8045Z-150M=P3 in all applications?

A: Direct replacement is valid only for applications where continuous current does not exceed 2.4 A. The SRN8040HA-150M has a lower current rating (2.4 A vs. 3.5 A) and higher DC resistance (86 mOhm vs. 52.8 mOhm). Applications requiring the full 3.5 A rating or lower resistance characteristics must use the DEM8045Z-150M=P3.

Q: What is the difference between shielded and semi-shielded configurations?

A: The DEM8045Z-150M=P3 features full shielding, providing complete electromagnetic containment. The SRN8040HA-150M uses semi-shielded construction, which provides partial electromagnetic isolation. Full shielding is required in applications with strict EMI/RFI suppression requirements or sensitive adjacent circuitry.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the DEM8045Z-150M=P3 and SRN8040HA-150M carry AEC-Q200 qualification, certifying suitability for automotive-grade reliability and performance standards.

Q: What is the physical size difference between these parts?

A: The DEM8045Z-150M=P3 measures 8.00mm L × 8.00mm W × 4.50mm H (seated). The SRN8040HA-150M measures 8.15mm L × 7.90mm W × 4.20mm H (seated). Both are classified as nonstandard packages and fit within comparable PCB footprints, though dimensional verification is required for space-constrained layouts.

Q: Do both parts meet ROHS3 compliance requirements?

A: Yes. Both the DEM8045Z-150M=P3 and SRN8040HA-150M are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for restricted substance control.

Q: What is the inductance tolerance for both parts?

A: Both parts maintain ±20% inductance tolerance, measured at 100 kHz. This tolerance applies equally to the DEM8045Z-150M=P3 and SRN8040HA-150M, ensuring consistent inductance performance across the specified range.

Q: Can the SRN8040HA-150M be used in high-temperature applications?

A: The SRN8040HA-150M operates to 150°C maximum, providing a 25°C thermal margin above the DEM8045Z-150M=P3 (125°C maximum). For applications requiring operation above 125°C, the SRN8040HA-150M is the appropriate selection, provided current requirements remain within its 2.4 A rating.
