Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCMA0703-2R2-R is determined by the following critical parameters:

Electrical Matching Criteria:

• Inductance value: 2.2 µH
• Inductance tolerance: ±20%
• Current rating: 8 A minimum
• Saturation current: 14 A minimum
• DC resistance: 20 mOhm maximum
• Shielding: Shielded configuration required

Mechanical & Environmental Criteria:

• Mounting type: Surface mount
• Operating temperature range: -55°C to 125°C minimum
• Inductance measurement frequency: 100 kHz
• Compliance: AEC-Q200 qualification
• RoHS3 compliance required

The IHLP2525CZER2R2MA1 from Vishay Dale meets all substitution criteria through identical electrical specifications and equivalent mechanical compatibility, despite differences in core material composition and physical dimensions within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the HCMA0703-2R2-R and IHLP2525CZER2R2MA1 are active production components with identical electrical performance specifications and full AEC-Q200 qualification. Selection between these parts is based on the following factors:

HCMA0703-2R2-R (Eaton - Electronics Division):

• Iron powder core construction
• Footprint: 7.10 mm x 6.80 mm
• Established supply availability: 969 pcs in stock

IHLP2525CZER2R2MA1 (Vishay Dale):

• Metal composite core construction
• Footprint: 6.86 mm x 6.47 mm (slightly smaller)
• Self-resonant frequency specified at 38 MHz
• Higher inventory availability: 4366 pcs in stock
• Packaging: Cut Tape & Digi-Reel format

Both parts satisfy ROHS3 compliance, REACH unaffected status, and identical operating temperature ranges. Physical dimensions are within acceptable tolerance for standard PCB layouts. Selection should be based on PCB layout constraints, packaging format requirements, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can IHLP2525CZER2R2MA1 directly replace HCMA0703-2R2-R in existing designs?

A: Yes. Both parts meet identical electrical specifications: 2.2 µH inductance at ±20% tolerance, 8 A current rating, 14 A saturation current, and 20 mOhm maximum DC resistance. Both are AEC-Q200 qualified and operate across -55°C to 125°C. Physical dimensions differ slightly (6.86 mm x 6.47 mm versus 7.10 mm x 6.80 mm), but both maintain 3.00 mm seated height. PCB layout verification is required for footprint compatibility.

Q: What is the significance of core material differences between these parts?

A: The HCMA0703-2R2-R uses iron powder core construction, while the IHLP2525CZER2R2MA1 uses metal composite core construction. Both achieve identical inductance, current rating, and DC resistance specifications. Core material differences do not affect electrical performance for this application category when all measured parameters are equivalent.

Q: Are there packaging format differences between these substitutes?

A: Yes. The HCMA0703-2R2-R is supplied in Tape & Reel (TR) format. The IHLP2525CZER2R2MA1 is supplied in Cut Tape (CT) & Digi-Reel format. Packaging selection depends on manufacturing process requirements and component handling equipment compatibility.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the HCMA0703-2R2-R and IHLP2525CZER2R2MA1 carry AEC-Q200 qualification, confirming suitability for automotive applications. Both are ROHS3 compliant and REACH unaffected.

Q: What is the self-resonant frequency consideration?

A: The IHLP2525CZER2R2MA1 specifies a self-resonant frequency of 38 MHz. The HCMA0703-2R2-R does not provide this specification. For applications operating near or above 38 MHz, the specified self-resonant frequency of the Vishay part provides additional design reference data. Both parts are tested and specified at 100 kHz inductance measurement frequency.

Q: How do moisture sensitivity levels compare?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard component storage conditions apply.
