HCP0703-8R2-R Equivalent & Substitute Parts

Part Overview

The HCP0703-8R2-R is an 8.2 µH shielded drum core wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is rated for 4 A continuous current with a maximum DC resistance of 68 mOhm and operates across the temperature range of -55°C to 125°C. The part is classified as obsolete, making equivalent and substitute components necessary for ongoing design support and procurement continuity. Substitute parts must maintain identical electrical specifications including inductance value, current rating, saturation current, DC resistance, and shielding characteristics to ensure functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCP0703-8R2-R are qualified based on strict electrical and mechanical parameter matching. All substitute components must satisfy the following criteria:

Critical Matching Parameters:

• Inductance value: 8.2 µH
• Inductance tolerance: ±20%
• Continuous current rating: 4 A minimum
• Saturation current (Isat): 7.5 A
• DC resistance: 68 mOhm maximum
• Shielding: Shielded configuration required
• Operating temperature range: Minimum -55°C to 125°C coverage
• Mounting type: Surface mount
• Moisture sensitivity: MSL 1 (Unlimited)

Substitute parts are grouped into two categories: direct manufacturer equivalents from Eaton and cross-manufacturer alternatives from qualified suppliers. Direct equivalents maintain identical core construction and material specifications. Cross-manufacturer alternatives may employ different core materials or construction methods but deliver equivalent electrical performance within the specified parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can the HCM0703-8R2-R directly replace the obsolete HCP0703-8R2-R?

A: Yes. The HCM0703-8R2-R is a direct equivalent manufactured by the same supplier (Eaton). Both parts share identical electrical specifications: 8.2 µH inductance, ±20% tolerance, 4 A current rating, 7.5 A saturation current, and 68 mOhm maximum DC resistance. The HCM0703-8R2-R is active in production and available in Tape & Reel packaging.

Q: What is the difference between the drum core wirewound and molded inductor designs?

A: The HCP0703-8R2-R and SRP7028A-8R2M employ drum core wirewound construction, while the IHLP2525CZER8R2M01 uses molded construction. Both designs deliver identical electrical performance within the specified parameters. Molded inductors typically offer improved mechanical robustness and consistent performance across temperature variations. Wirewound inductors may provide lower parasitic capacitance in certain applications. Selection depends on specific circuit requirements and mechanical constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The HCM0703-8R2-R, IHLP2525CZER8R2M01, and SRP7028A-8R2M are all ROHS3 compliant and REACH unaffected. The original HCP0703-8R2-R RoHS status is not specified in the documentation.

Q: What are the physical dimension differences between substitute parts?

A: The HCP0703-8R2-R measures 7.30mm L x 7.00mm W x 3.00mm H. The HCM0703-8R2-R measures 7.10mm L x 6.60mm W x 3.00mm H. The IHLP2525CZER8R2M01 measures 6.86mm L x 6.47mm W x 3.00mm H. The SRP7028A-8R2M measures 7.30mm L x 6.60mm W x 3.00mm H. All parts maintain identical height (3.00mm) and are surface mount compatible. Verify PCB layout clearances for length and width variations.

Q: Which substitute part offers the widest operating temperature range?

A: The SRP7028A-8R2M operates from -40°C to 150°C, providing extended high-temperature capability compared to the HCP0703-8R2-R, HCM0703-8R2-R, and IHLP2525CZER8R2M01, which all operate from -55°C to 125°C. Select the SRP7028A-8R2M for applications requiring operation above 125°C.

Q: Does the SRP7028A-8R2M include automotive qualification?

A: Yes. The SRP7028A-8R2M carries AEC-Q200 automotive qualification. This rating is not specified for the other substitute parts. Select the SRP7028A-8R2M for automotive applications requiring AEC-Q200 compliance.
