Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCMA0703-6R8-R are qualified based on the following electrical and mechanical parameters:

Primary Matching Criteria:

• Inductance value: 6.8 µH
• Inductance tolerance: ±20%
• Shielding: Shielded configuration
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 125°C
• AEC-Q200 qualification
• RoHS3 compliance

Secondary Compatibility Parameters:

• Current rating: minimum 4.5 A
• DC resistance: maximum 60 mOhm
• Saturation current: minimum 8 A
• Package type: Tape & Reel (TR)

The identified substitute parts IHLP2525CZER6R8M1A and IHLP2525CZER6R8MA1 from Vishay Dale meet or exceed the primary electrical specifications and maintain full compliance with automotive and environmental standards. Variations in physical dimensions and core material composition remain within acceptable mechanical envelope constraints for standard surface mount PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

IHLP2525CZER6R8MA1 (Vishay Dale) is the primary substitute for direct replacement of HCMA0703-6R8-R. This part maintains identical electrical specifications including 4.5 A current rating, 8 A saturation current, and 60 mOhm maximum DC resistance. Both components carry AEC-Q200 automotive qualification and ROHS3 compliance. The molded construction type and identical operating temperature range (-55°C to 125°C) ensure functional equivalence in circuit applications. Physical dimensions are comparable (0.270" L x 0.255" W vs. 0.280" L x 0.268" W), with identical seated height of 0.118" (3.00 mm), supporting standard PCB assembly compatibility.

IHLP2525CZER6R8M1A (Vishay Dale) serves as an alternative substitute with enhanced electrical performance characteristics. This variant provides higher current rating (5.5 A vs. 4.5 A) and lower DC resistance (46.8 mOhm vs. 60 mOhm maximum), offering improved thermal performance in current-limited applications. However, the saturation current specification (4 A) is lower than the primary part (8 A), requiring circuit-level evaluation for applications approaching saturation conditions. This part maintains full AEC-Q200 and ROHS3 compliance with identical operating temperature range and packaging format.

Both substitute parts are Active products with confirmed inventory availability and maintain all required automotive and environmental certifications for direct component selection.

Frequently Asked Questions (FAQ)

Q: Can IHLP2525CZER6R8MA1 be used as a direct drop-in replacement for HCMA0703-6R8-R?

A: Yes. Both parts share identical inductance (6.8 µH), tolerance (±20%), current rating (4.5 A), saturation current (8 A), and DC resistance (60 mOhm maximum). Operating temperature range, shielding configuration, and AEC-Q200 qualification are identical. Physical dimensions are comparable with equivalent seated height, supporting standard surface mount assembly processes.

Q: What is the key difference between the two Vishay Dale substitutes?

A: IHLP2525CZER6R8M1A provides higher current rating (5.5 A) and lower DC resistance (46.8 mOhm), but features lower saturation current (4 A). IHLP2525CZER6R8MA1 matches the original part specifications exactly. Selection depends on application current requirements and saturation margin requirements.

Q: Are all three parts qualified for automotive applications?

A: Yes. HCMA0703-6R8-R, IHLP2525CZER6R8M1A, and IHLP2525CZER6R8MA1 all carry AEC-Q200 automotive qualification and ROHS3 compliance, supporting use in automotive and industrial applications with equivalent reliability standards.

Q: Do the substitute parts have different moisture sensitivity requirements?

A: No. All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity limitations for storage, handling, or assembly processes.

Q: Can physical dimension differences affect PCB layout compatibility?

A: The substitute parts have slightly smaller footprints (0.270" L x 0.255" W vs. 0.280" L x 0.268" W) with identical seated height (0.118"). These differences are within standard PCB assembly tolerances and do not affect component placement or electrical performance in standard surface mount applications.
