Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCMA0703-3R3-R is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 3.3 µH
• Inductance tolerance: ±20%
• Current rating: 6 A minimum
• Saturation current (Isat): 13.5 A minimum
• DC resistance: 30 mOhm maximum
• Shielding: Shielded configuration

Mechanical & Environmental Requirements:

• Operating temperature range: -55°C to 125°C minimum
• Mounting type: Surface Mount
• Packaging: Tape & Reel (TR)
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Requirements:

• AEC-Q200 automotive qualification
• RoHS3 compliance
• REACH unaffected status

The IHLP2525CZER3R3MA1 manufactured by Vishay Dale qualifies as a direct substitute because it maintains all critical electrical parameters, operates within the required temperature range, carries identical AEC-Q200 and RoHS3 certifications, and is supplied in Tape & Reel packaging suitable for surface mount assembly.

Parameter Comparison

Engineering Selection Recommendations

Both the HCMA0703-3R3-R and IHLP2525CZER3R3MA1 maintain Active product status and carry full AEC-Q200 automotive qualification with RoHS3 compliance. Selection between these parts is based on the following factors:

HCMA0703-3R3-R (Eaton - Electronics Division):

• Iron powder drum core construction
• Established supply chain with 657 pieces in current inventory
• Nonstandard package configuration

IHLP2525CZER3R3MA1 (Vishay Dale):

• Metal composite core construction
• Higher inventory availability with 2100 pieces in stock
• Specified self-resonant frequency of 30 MHz
• Slightly reduced physical footprint (6.86mm x 6.47mm vs. 7.10mm x 6.80mm)
• Nonstandard package configuration

Both parts satisfy all electrical, thermal, and compliance requirements for direct substitution in surface mount applications requiring 3.3 µH inductance at 6 A continuous current.

Frequently Asked Questions (FAQ)

Q: Can IHLP2525CZER3R3MA1 replace HCMA0703-3R3-R in existing designs?

A: Yes. Both inductors maintain identical electrical specifications (3.3 µH, ±20% tolerance, 6 A rating, 30 mOhm DCR maximum), operate across -55°C to 125°C, carry AEC-Q200 qualification, and are supplied in Tape & Reel surface mount packaging. Physical dimensions are similar with maximum seated height of 3.00mm for both parts.

Q: What is the difference in core material between these parts?

A: The HCMA0703-3R3-R uses iron powder core construction, while the IHLP2525CZER3R3MA1 uses metal composite core construction. Both achieve the specified inductance value and saturation current rating. Core material differences do not affect electrical parameter equivalence for this application.
