Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCM0503-1R5-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 1.5 µH
• Inductance tolerance: ±20%
• Shielding: Shielded construction
• Mounting type: Surface Mount
• Inductance test frequency: 100 kHz

Secondary Compatibility Criteria:

• Current rating: minimum 7.5 A (or higher)
• DC resistance: 19 mOhm maximum (or lower)
• Operating temperature range: -55°C to 125°C (or wider)
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The substitute parts listed below satisfy the primary matching criteria. Variations in current rating, saturation current, and DC resistance are noted where they differ from the main part specification.

Engineering Selection Recommendations

IHLP2020CZER1R5M11 (Direct Substitute)

This Vishay Dale component matches the HCM0503-1R5-R across all critical electrical parameters: 1.5 µH inductance, 7.5 A current rating, and identical operating temperature range (-55°C to 125°C). The DC resistance of 18.5 mOhm is lower than the 19 mOhm maximum specification, providing improved thermal performance. Both parts maintain ROHS3 compliance and MSL 1 rating. The primary difference is construction type (molded versus drum core wirewound) and packaging format (Tape & Reel versus Cut Tape). This part is suitable for direct substitution in applications where the molded construction is acceptable.

IHLP2020CZER1R5M01 (Similar Substitute)

This Vishay Dale component provides 1.5 µH inductance with a 7.2 A current rating, which is within 96% of the main part specification. The DC resistance of 20.7 mOhm exceeds the 19 mOhm maximum by 1.7 mOhm. Operating temperature range matches the main part (-55°C to 125°C). ROHS3 compliance and MSL 1 rating are maintained. This part is suitable for applications where the slightly elevated DC resistance and reduced current rating are acceptable within circuit design margins.

PA4340.152NLT (Limited Substitute)

This Pulse Electronics component provides 1.5 µH inductance with a 6 A current rating, which is 80% of the main part specification. The DC resistance of 25 mOhm exceeds the 19 mOhm maximum by 6 mOhm. The operating temperature range is narrower (-40°C to 125°C) compared to the main part. This part includes AEC-Q200 automotive qualification. Substitution is limited to applications where the reduced current rating and elevated DC resistance fall within acceptable design parameters.

Frequently Asked Questions (FAQ)

Q: Can IHLP2020CZER1R5M11 be used as a direct replacement for HCM0503-1R5-R?

A: Yes. Both components share identical inductance (1.5 µH), current rating (7.5 A), tolerance (±20%), operating temperature range (-55°C to 125°C), and test frequency (100 kHz). The IHLP2020CZER1R5M11 features lower DC resistance (18.5 mOhm versus 19 mOhm maximum), which is advantageous. The primary difference is construction method (molded versus drum core wirewound). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the impact of using PA4340.152NLT as a substitute?

A: The PA4340.152NLT has a reduced current rating of 6 A compared to the 7.5 A specification of the HCM0503-1R5-R. Additionally, the DC resistance is 25 mOhm, which exceeds the 19 mOhm maximum by 6 mOhm. The operating temperature range is narrower (-40°C to 125°C). This part is suitable only for applications where these deviations are within acceptable design margins.

Q: How do the physical dimensions compare between these parts?

A: The HCM0503-1R5-R measures 0.203" L × 0.201" W × 0.118" H (5.15mm × 5.10mm × 3.00mm). The IHLP2020CZER1R5M11 and IHLP2020CZER1R5M01 measure 0.216" L × 0.204" W × 0.118" H (5.49mm × 5.18mm × 3.00mm). The PA4340.152NLT measures 0.236" L × 0.213" W × 0.118" H (6.00mm × 5.40mm × 3.00mm). Height is identical across all parts. Length and width variations must be evaluated against PCB layout constraints.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The HCM0503-1R5-R and all listed substitute parts (IHLP2020CZER1R5M11, PA4340.152NLT, and IHLP2020CZER1R5M01) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: The HCM0503-1R5-R is supplied in Cut Tape (CT) format, suitable for manual handling and smaller quantity orders. The substitute parts are supplied in Tape & Reel (TR) format, optimized for automated assembly equipment and higher volume production. Packaging format selection depends on manufacturing process requirements and order quantities.

Q: Which substitute part has the lowest DC resistance?

A: The IHLP2020CZER1R5M11 has the lowest DC resistance at 18.5 mOhm maximum, compared to 19 mOhm for the main part and higher values for the other substitutes.
