Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCP0703-100-R are identified based on strict electrical and mechanical parameter alignment. The critical parameters governing substitution are:

Electrical Parameters:

• Inductance value: 10 µH (exact match required)
• Current rating: minimum 3 A continuous
• DC resistance: maximum 105 mOhm
• Saturation current: minimum 7 A
• Operating temperature range: -55°C to 125°C (minimum requirement)
• Shielding: shielded configuration

Mechanical Parameters:

• Mounting type: surface mount
• Height seated (max): 3.00 mm
• Tolerance: ±20%

Substitute parts are classified into two categories:

Direct Substitute (HCM0703-100-R): Active product from the same manufacturer series with improved electrical performance (lower DCR at 77.6 mOhm) and higher current rating (3.2 A), maintaining identical inductance and core material specifications.

Similar Substitute (IHLP2525CZER100M01): Active product from alternative manufacturer (Vishay Dale) with identical electrical specifications but different core construction (molded vs. drum core) and slightly different physical dimensions, maintaining functional equivalence.

Engineering Selection Recommendations

HCM0703-100-R (Recommended Primary Substitute):

The HCM0703-100-R is the preferred direct substitute for the obsolete HCP0703-100-R. Both components are manufactured by Eaton - Electronics Division and share identical inductance, tolerance, saturation current, operating temperature range, and core material specifications. The HCM0703-100-R is an active product with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory alignment. The improved DC resistance specification (77.6 mOhm vs. 105 mOhm) and higher current rating (3.2 A vs. 3 A) provide enhanced performance margins without compromising functional compatibility. Physical dimensions remain within acceptable tolerances for existing PCB layouts.

IHLP2525CZER100M01 (Alternative Substitute):

The IHLP2525CZER100M01 from Vishay Dale provides functional equivalence with identical electrical specifications for inductance, current rating, DC resistance, saturation current, and operating temperature range. This component is an active product with ROHS3 compliance and REACH unaffected status. The primary distinction is the molded core construction versus the drum core wirewound design of the main part. Physical dimensions are slightly reduced (6.86 mm × 6.47 mm vs. 7.30 mm × 7.00 mm), which may require PCB layout verification for existing designs. This substitute is suitable when space constraints favor the smaller footprint or when Vishay Dale component qualification is required.

Frequently Asked Questions (FAQ)

Q: Can HCM0703-100-R directly replace HCP0703-100-R in existing designs?

A: Yes. The HCM0703-100-R maintains all critical electrical parameters: 10 µH inductance, 3 A minimum current rating (3.2 A actual), 105 mOhm maximum DC resistance (77.6 mOhm actual), 7 A saturation current, and -55°C to 125°C operating range. Physical height is identical at 3.00 mm. The improved performance characteristics present no compatibility issues.

Q: What is the primary difference between HCM0703-100-R and IHLP2525CZER100M01?

A: Both parts meet the electrical requirements of the HCP0703-100-R. The HCM0703-100-R uses drum core wirewound construction with iron powder core material, matching the original design. The IHLP2525CZER100M01 uses molded construction with unspecified core material. Physical dimensions differ slightly: HCM0703-100-R is 7.10 mm × 6.60 mm, while IHLP2525CZER100M01 is 6.86 mm × 6.47 mm. Both maintain 3.00 mm maximum seated height.

Q: Are there packaging differences between the substitute parts?

A: Yes. The HCP0703-100-R packaging is not specified. The HCM0703-100-R is supplied in Tape & Reel (TR) format. The IHLP2525CZER100M01 is supplied in Cut Tape (CT) & Digi-Reel® format. Procurement and assembly processes should account for these packaging differences.

Q: Do the substitute parts meet current regulatory requirements?

A: The HCM0703-100-R and IHLP2525CZER100M01 are both ROHS3 compliant and REACH unaffected. The original HCP0703-100-R regulatory status is not specified. Both substitutes meet current environmental and regulatory standards for new designs and procurement.

Q: What is the significance of the lower DC resistance in HCM0703-100-R?

A: The HCM0703-100-R specifies 77.6 mOhm maximum DC resistance compared to 105 mOhm for the HCP0703-100-R. This represents improved electrical efficiency with reduced resistive losses. For applications sensitive to power dissipation or thermal performance, the HCM0703-100-R provides enhanced performance margins.

Q: Can IHLP2525CZER100M01 be used if space is constrained?

A: The IHLP2525CZER100M01 has a smaller footprint (6.86 mm × 6.47 mm vs. 7.30 mm × 7.00 mm) while maintaining identical 3.00 mm height. If PCB layout permits the reduced dimensions, this part accommodates space-constrained designs. Verify pad spacing and layout compatibility before implementation.

Q: What inventory status should influence part selection?

A: The HCM0703-100-R has 1,477 pieces in stock (active product), and IHLP2525CZER100M01 has 25,100 pieces in stock (active product). Both substitutes offer superior availability compared to the obsolete HCP0703-100-R with 1,400 pieces remaining. For long-term production, the IHLP2525CZER100M01 offers the highest inventory buffer.
