Key Parameters

Substitute Part Grouping Explanation

Substitute parts are qualified based on strict equivalence across the following critical parameters:

Electrical specifications: Inductance value (3.3 µH), tolerance (±20%), current rating (8.1 A), saturation current (8.7 A), and DC resistance (23.1 mOhm max) must match exactly.

Mechanical compatibility: Package type (5030 Nonstandard), physical dimensions (5.50mm x 5.30mm x 3.10mm), and surface mount configuration must be identical.

Environmental and compliance requirements: Operating temperature range (-40°C to 125°C), AEC-Q200 qualification, RoHS3 compliance, and MSL rating (1) must be maintained.

The ASPIAIG-F5030-3R3M-T from Abracon LLC meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ECS-HCMPI-0503Q-3R3M-T and ASPIAIG-F5030-3R3M-T are active products with identical electrical and mechanical specifications. Selection between these parts is based on availability, lead time, and supply chain requirements. Both components maintain AEC-Q200 automotive qualification and ROHS3 compliance, ensuring compatibility in regulated applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for storage or handling. Component selection should prioritize inventory availability and procurement timelines without compromising electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the ASPIAIG-F5030-3R3M-T be used as a direct replacement for the ECS-HCMPI-0503Q-3R3M-T?

A: Yes. Both parts are electrically and mechanically equivalent with identical inductance (3.3 µH), current ratings (8.1 A), DC resistance (23.1 mOhm max), physical dimensions (5.50mm x 5.30mm x 3.10mm), and compliance certifications (AEC-Q200, ROHS3).

Q: Are there any PCB layout or footprint differences between these parts?

A: No. Both components use the identical 5030 nonstandard package with matching physical dimensions and surface mount configuration. PCB footprints are interchangeable.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the ECS-HCMPI-0503Q-3R3M-T and ASPIAIG-F5030-3R3M-T carry AEC-Q200 qualification and operate across the -40°C to 125°C temperature range required for automotive applications.

Q: What is the significance of the MSL rating of 1?

A: MSL 1 (Unlimited) indicates these components have no moisture sensitivity limitations. Standard storage and handling procedures apply without special moisture control requirements.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8504.50.8000).
