Substitute Part Grouping Explanation

Substitute parts for the HCM1305-8R2-R are qualified based on the following electrical and mechanical parameters:

Primary Matching Criteria:

• Inductance value: 8.2 µH (exact match required)
• Tolerance: ±20% (matching specification)
• Current rating: minimum 9.5 A continuous
• Saturation current: minimum 18 A
• Shielding: Shielded construction
• Mounting: Surface mount configuration
• Operating temperature range: -55°C to 125°C minimum
• RoHS3 compliance
• MSL rating: 1 (Unlimited)
• Inductance test frequency: 100 kHz

Secondary Compatibility Factors:

• DC resistance within acceptable limits for the application
• Nonstandard package classification
• Tape & Reel packaging format
• Active product status

The identified substitute parts meet or exceed these criteria, ensuring electrical and mechanical compatibility with the original HCM1305-8R2-R specification.

Parameter Comparison

Engineering Selection Recommendations

IHLP5050EZER8R2M01 (Vishay Dale): This substitute maintains electrical equivalence with the HCM1305-8R2-R across all critical parameters. The inductance, tolerance, current rating, and saturation current are identical. The DC resistance specification of 22.5 mOhm is marginally higher than the original 20.1 mOhm maximum, representing a 2.4 mOhm increase. Both parts share identical operating temperature range, RoHS3 compliance, and MSL rating. This part is suitable for direct substitution in applications where the slightly elevated DC resistance is acceptable within circuit design margins.

PA4343.822NLT (Pulse Electronics): This substitute provides enhanced current handling capability at 10.5 A continuous rating, exceeding the original 9.5 A specification. The DC resistance is reduced to 15.5 mOhm maximum, providing lower losses compared to the HCM1305-8R2-R. However, the saturation current specification of 15.5 A is lower than the original 18 A rating. The operating temperature range is -40°C to 125°C, which does not extend to the lower -55°C limit of the original part. This substitute is applicable in applications operating above -40°C where the enhanced current rating and reduced DC resistance provide performance benefits. The part carries AEC-Q200 automotive qualification and REACH compliance status.

Both substitute parts maintain active production status and are available in volume quantities with Tape & Reel packaging suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the IHLP5050EZER8R2M01 be used as a direct replacement for the HCM1305-8R2-R?

A: Yes. Both parts share identical inductance (8.2 µH), tolerance (±20%), current rating (9.5 A), saturation current (18 A), operating temperature range (-55°C to 125°C), and compliance certifications (RoHS3, MSL 1). The DC resistance difference of 2.4 mOhm is within typical circuit design tolerances for inductor applications.

Q: What is the key difference between the PA4343.822NLT and the original HCM1305-8R2-R?

A: The PA4343.822NLT provides higher continuous current capability (10.5 A versus 9.5 A) and lower DC resistance (15.5 mOhm versus 20.1 mOhm). However, its saturation current is 15.5 A compared to 18 A, and its minimum operating temperature is -40°C rather than -55°C. Selection depends on application requirements for temperature range and saturation margin.

Q: Are all three parts available in the same packaging format?

A: Yes. The HCM1305-8R2-R, IHLP5050EZER8R2M01, and PA4343.822NLT are all supplied in Tape & Reel (TR) packaging suitable for surface mount assembly processes.

Q: What compliance certifications apply to these substitute parts?

A: All three parts are RoHS3 compliant with MSL rating of 1 (Unlimited). The PA4343.822NLT additionally carries AEC-Q200 automotive qualification and REACH compliance status.

Q: Can the PA4343.822NLT be used in applications requiring -55°C operation?

A: No. The PA4343.822NLT operating temperature range is -40°C to 125°C. For applications requiring -55°C minimum temperature operation, the HCM1305-8R2-R or IHLP5050EZER8R2M01 must be used.

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

A: The HCM1305-8R2-R measures 13.30mm L × 12.20mm W × 5.00mm H. The IHLP5050EZER8R2M01 measures 13.20mm L × 12.90mm W × 5.00mm H. The PA4343.822NLT measures 14.00mm L × 12.80mm W × 6.50mm H. PCB layout verification is required when substituting the PA4343.822NLT due to increased height.
