Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 701014150 is determined by strict alignment across the following critical parameters:

Inductance value must match at 1.5 µH with identical ±25% tolerance specification. DC resistance must remain at 0.6 mOhm to preserve circuit performance and thermal characteristics. Shielding configuration must be maintained as shielded to ensure electromagnetic compatibility. Operating temperature range must encompass or equal -40°C to 150°C. Surface mount mounting type and nonstandard package dimensions (27.50 mm × 27.50 mm footprint with 17.00 mm maximum seated height) must be preserved. AEC-Q200 qualification is required for automotive and high-reliability applications.

The substitute part 78436432015 meets these criteria with the following distinction: current rating is specified at 47 A versus the original 50 A, with saturation current (Isat) at 53 A compared to 45 A in the original part. This represents a functional equivalent suitable for applications where the 47 A continuous current rating satisfies circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The 78436432015 is an active production equivalent for the obsolete 701014150. Both components maintain identical inductance, DC resistance, shielding, temperature range, and physical footprint specifications. The primary design consideration is current rating: the substitute part is rated for 47 A continuous current versus 50 A in the original part.

Selection of the 78436432015 is appropriate for applications where the circuit current requirement does not exceed 47 A. Both parts carry AEC-Q200 qualification and RoHS3 compliance, ensuring regulatory and automotive standards alignment. The substitute part's higher saturation current (53 A versus 45 A) provides improved headroom against saturation-induced inductance collapse in transient conditions.

Frequently Asked Questions (FAQ)

Q: Can the 78436432015 directly replace the 701014150 in all applications?

A: Direct replacement is valid only when circuit current requirements do not exceed 47 A continuous. The substitute part maintains identical inductance, DC resistance, shielding, temperature range, and physical dimensions. If the original design requires the full 50 A rating, the substitute is not suitable.

Q: Are the physical footprints identical?

A: Yes. Both parts share identical surface mount package dimensions of 27.50 mm × 27.50 mm with maximum seated height of 17.00 mm. PCB layout and mechanical mounting are interchangeable.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the 701014150 and 78436432015 carry AEC-Q200 qualification and are RoHS3 compliant, meeting automotive and high-reliability application requirements.

Q: What is the significance of the different saturation current values?

A: The 78436432015 has a saturation current of 53 A compared to 45 A in the 701014150. This indicates improved core material performance in the substitute part, providing greater margin against inductance degradation during current transients.

Q: Is the 78436432015 currently available?

A: Yes. The 78436432015 is classified as active production status with documented inventory availability, whereas the 701014150 is obsolete.
