Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCM1305-5R6-R are qualified based on the following electrical and mechanical parameters:

Primary Matching Criteria:

• Inductance value: 5.6 µH
• Inductance tolerance: ±20%
• Current rating: minimum 11.5 A
• Saturation current: minimum 22 A
• Shielding: Shielded construction required
• Operating temperature range: -55°C to 125°C minimum
• Mounting type: Surface Mount
• RoHS3 compliance: Required

Secondary Considerations:

• DC resistance within acceptable limits for application
• Nonstandard package classification
• Tape & Reel packaging format
• MSL rating of 1 (Unlimited)

The two identified substitute parts meet these criteria through alternative core construction methods (molded versus drum core wirewound) while maintaining equivalent electrical performance at the specified current and inductance levels.

Engineering Selection Recommendations

HCM1305-5R6-R (Eaton - Electronics Division)

Primary selection for applications requiring drum core wirewound construction with the lowest DC resistance specification at 13.8 mOhm maximum. Maintains full temperature range operation from -55°C to 125°C. RoHS3 compliant with unlimited moisture sensitivity rating. Active product status with established supply availability.

IHLP5050EZER5R6M01 (Vishay Dale)

Qualified substitute offering molded inductor construction with identical current rating and saturation specifications. DC resistance of 16.5 mOhm represents a 19.6% increase over the main part. Maintains full -55°C to 125°C operating range and RoHS3 compliance. Footprint dimensions are comparable with minimal height variation. Active product status with 974 units in stock.

PA4343.562NLT (Pulse Electronics)

Qualified substitute with enhanced current rating of 12.5 A and superior DC resistance of 10 mOhm, representing a 27.5% reduction compared to the main part. Saturation current of 23 A exceeds specification. Operating temperature range limited to -40°C to 125°C, reducing lower temperature capability by 15°C. Includes AEC-Q200 automotive qualification. RoHS3 and REACH compliant. Largest footprint with 6.50 mm maximum height. Highest inventory availability at 2577 units.

Frequently Asked Questions (FAQ)

Q: Can the IHLP5050EZER5R6M01 be used as a direct replacement for the HCM1305-5R6-R?

A: Yes. Both parts share identical inductance (5.6 µH), current rating (11.5 A), saturation current (22 A), operating temperature range (-55°C to 125°C), and shielding characteristics. The primary difference is core construction type (molded versus drum core wirewound) and DC resistance specification (16.5 mOhm versus 13.8 mOhm). Applications sensitive to resistive losses should evaluate the 2.7 mOhm increase.

Q: Is the PA4343.562NLT suitable for low-temperature applications below -40°C?

A: No. The PA4343.562NLT operating temperature range is -40°C to 125°C, which does not extend to the -55°C lower limit of the HCM1305-5R6-R. Applications requiring operation at -55°C must use either the main part or the IHLP5050EZER5R6M01.

Q: What are the footprint differences between these three parts?

A: The HCM1305-5R6-R measures 13.30mm L x 12.20mm W x 5.00mm H. The IHLP5050EZER5R6M01 measures 13.20mm L x 12.90mm W x 5.00mm H, offering nearly identical height with slightly increased width. The PA4343.562NLT measures 14.00mm L x 12.80mm W x 6.50mm H, representing the largest footprint with 1.50 mm additional height. PCB layout constraints may restrict the PA4343.562NLT in space-limited applications.

Q: How do the DC resistance values affect component selection?

A: DC resistance directly impacts resistive losses and thermal performance. The PA4343.562NLT offers the lowest DCR at 10 mOhm, reducing I²R losses by 27.5% compared to the main part. The IHLP5050EZER5R6M01 at 16.5 mOhm increases losses by 19.6%. Selection depends on thermal budget and efficiency requirements of the application.

Q: Are all three parts RoHS3 compliant?

A: Yes. The HCM1305-5R6-R, IHLP5050EZER5R6M01, and PA4343.562NLT are all RoHS3 compliant. The PA4343.562NLT additionally carries REACH compliance status.

Q: What is the significance of the ±20% inductance tolerance across all parts?

A: All three parts share identical ±20% inductance tolerance at the 100 kHz test frequency. This tolerance specification is consistent across manufacturers and does not differentiate substitution suitability.

Q: Does the PA4343.562NLT AEC-Q200 rating provide additional qualification value?

A: AEC-Q200 certification indicates automotive-grade qualification with defined reliability and stress testing protocols. This certification is relevant only for applications requiring automotive compliance. Non-automotive applications do not require this qualification.
