Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VCHA075D-150MS6P is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 15 µH (fixed requirement)
• Inductance tolerance: ±20% (fixed requirement)
• Mounting type: Surface Mount (fixed requirement)
• Inductance test frequency: 100 kHz (fixed requirement)

Secondary Compatibility Criteria:

• Current rating must equal or exceed 3.8 A
• DC resistance must not exceed 66 mOhm
• Operating temperature range must encompass -55°C ~ 165°C or be compatible with application limits
• AEC-Q200 certification required for automotive applications
• RoHS3 compliance required

Flexible Parameters:

• Shielding type (unshielded or shielded acceptable based on EMI requirements)
• Package dimensions (minor variations acceptable if mounting footprint compatible)
• Saturation current (higher values acceptable)

The two substitute parts listed below meet all primary matching criteria and secondary compatibility requirements.

Parameter Comparison

Engineering Selection Recommendations

HCM1A0805V2-150-R (Eaton - Electronics Division)

This substitute meets all primary inductance and tolerance requirements with a current rating of 4 A, exceeding the 3.8 A requirement of the main part. DC resistance is 52 mOhm, which is lower than the 66 mOhm maximum, resulting in reduced power dissipation. The component features shielding, which provides EMI containment benefits in noise-sensitive applications. The operating temperature range extends to 155°C, which is 10°C lower than the main part's maximum. AEC-Q200 certification and ROHS3 compliance are maintained. Package dimensions are slightly larger (8.10mm x 8.00mm), requiring PCB layout verification for footprint compatibility.

SRP7050WA-150M (Bourns Inc.)

This substitute provides the highest current rating at 5.5 A with saturation current of 7.2 A, offering the greatest margin above the 3.8 A requirement. DC resistance matches the main part at 66 mOhm maximum. The component includes shielding and maintains the full operating temperature range of -55°C ~ 165°C, matching the main part exactly. AEC-Q200 certification and ROHS3 compliance are confirmed. Package dimensions (7.90mm x 7.30mm) are closest to the main part, minimizing PCB layout modifications. Q factor specification of 20 @ 100kHz is provided.

Both substitutes maintain Active product status and full compliance certifications required for automotive and high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can HCM1A0805V2-150-R be used as a direct replacement for VCHA075D-150MS6P?

A: HCM1A0805V2-150-R meets all electrical requirements with matching inductance, tolerance, and current rating specifications. The primary consideration is package dimension compatibility. The substitute measures 8.10mm x 8.00mm compared to 7.70mm x 7.20mm for the main part. PCB layout verification is required to confirm the larger footprint fits within available space constraints.

Q: What is the difference between shielded and unshielded versions?

A: The main part (VCHA075D-150MS6P) is unshielded, while both substitutes (HCM1A0805V2-150-R and SRP7050WA-150M) are shielded. Shielding reduces electromagnetic interference emission and susceptibility. In applications where EMI control is critical, shielded substitutes provide additional performance benefits. In applications where shielding is not required, unshielded designs may offer cost advantages, but these substitutes are shielded.

Q: Does the lower operating temperature limit of HCM1A0805V2-150-R affect compatibility?

A: HCM1A0805V2-150-R operates to 155°C maximum, compared to 165°C for the main part. This 10°C difference is acceptable for applications where the maximum operating temperature does not exceed 155°C. For applications requiring operation at temperatures between 155°C and 165°C, SRP7050WA-150M is the appropriate substitute, as it maintains the full -55°C ~ 165°C range.

Q: Are all three parts AEC-Q200 certified?

A: Yes. VCHA075D-150MS6P, HCM1A0805V2-150-R, and SRP7050WA-150M all carry AEC-Q200 certification, confirming suitability for automotive and high-reliability applications.

Q: What is the impact of lower DC resistance in HCM1A0805V2-150-R?

A: The 52 mOhm DC resistance of HCM1A0805V2-150-R is lower than the 66 mOhm maximum of the main part. Lower DC resistance reduces power dissipation and heat generation during operation, which is a beneficial characteristic. This does not create compatibility issues; it represents an improvement in thermal performance.

Q: Can package dimension differences affect circuit performance?

A: Package dimension differences affect PCB layout and mounting only. Electrical performance is determined by inductance, tolerance, current rating, and DC resistance specifications. Larger package dimensions (HCM1A0805V2-150-R at 8.10mm x 8.00mm) require verification that the component fits within available PCB space. Smaller dimension variations (SRP7050WA-150M at 7.90mm x 7.30mm) typically require minimal layout adjustment.
