Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCM1104-4R7-R are classified based on strict alignment with the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 4.7 µH (±20% tolerance)
• Shielding: Shielded configuration required
• Mounting: Surface mount technology
• Inductance test frequency: 100 kHz
• Moisture sensitivity: MSL 1 (Unlimited)

Secondary Compatibility Factors:

• Current rating: Minimum 8.5 A continuous (saturation current ≥15 A)
• DC resistance: Maximum 20 mOhm preferred
• Operating temperature: Minimum -55°C to 125°C overlap required
• Package dimensions: Nonstandard form factor with height ≤4.00 mm seated

Direct Substitutes maintain all primary criteria with equivalent or superior current handling and DC resistance characteristics.

Similar Substitutes meet primary criteria but may have variations in current rating, DC resistance, or saturation current that require application-level verification of thermal and electrical margins.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Preferred):

PA4342.472NLT (Pulse Electronics) and SRP1038A-4R7M (Bourns Inc.) are direct substitutes. Both parts exceed the HCM1104-4R7-R current rating (10 A vs. 8.5 A), provide lower DC resistance (15.5 mOhm vs. 20 mOhm maximum), and maintain saturation current ≥17 A. Both are ROHS3 compliant with MSL 1 rating. SRP1038A-4R7M includes AEC-Q200 automotive qualification and extended operating temperature to 150°C. PA4342.472NLT operates to -40°C minimum versus -55°C for the original part.

Similar Substitutes (Application-Dependent):

IHLP4040DZER4R7M01 (Vishay Dale) provides 9.5 A continuous current with 16.5 mOhm DCR and maintains the full -55°C to 125°C temperature range. This part is suitable for applications where the 8.5 A rating is adequate with thermal margin.

IHLP4040DZER4R7M11 (Vishay Dale) offers the lowest DC resistance at 14.2 mOhm but has reduced saturation current (7.6 A). This part is not suitable for applications requiring the full 15 A saturation margin of the original part.

MPLC1040L4R7 (KEMET) has reduced current rating (8 A) and saturation current (8 A) with narrower operating temperature range (-20°C to 120°C). This part is not recommended as a substitute due to insufficient current handling and temperature range limitations.

All substitute parts maintain 4.7 µH inductance at ±20% tolerance, shielded configuration, surface mount technology, and 100 kHz test frequency.

Frequently Asked Questions (FAQ)

Q: Can PA4342.472NLT replace HCM1104-4R7-R in all applications?

A: PA4342.472NLT is a direct substitute with superior electrical performance (higher current rating, lower DCR). The primary consideration is the minimum operating temperature: PA4342.472NLT operates to -40°C while HCM1104-4R7-R operates to -55°C. Applications requiring operation below -40°C require the original part or SRP1038A-4R7M.

Q: What is the difference between drum core and molded inductor types in this comparison?

A: Drum core inductors (HCM1104-4R7-R, SRP1038A-4R7M) use exposed wire windings on a core material. Molded inductors (PA4342.472NLT, IHLP4040DZER series) encapsulate the winding in a molded compound. Both are shielded. Molded types typically offer better mechanical robustness and consistent performance across temperature ranges. Drum core types may provide lower parasitic capacitance in specific applications.

Q: Why does IHLP4040DZER4R7M11 have lower saturation current than other parts?

A: Saturation current is determined by core material composition and winding design. IHLP4040DZER4R7M11 is optimized for lower DC resistance (14.2 mOhm) at the cost of reduced saturation margin. Applications requiring full 15 A saturation headroom should not use this part.

Q: Are all substitute parts RoHS compliant?

A: Yes. HCM1104-4R7-R is RoHS Compliant. All substitute parts listed are ROHS3 Compliant, which represents the current RoHS directive standard. ROHS3 compliance includes all RoHS Compliant requirements.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements prior to reflow soldering. All parts in this comparison carry MSL 1 rating, ensuring no additional moisture handling procedures are necessary during assembly.

Q: Can MPLC1040L4R7 be used as a substitute?

A: MPLC1040L4R7 meets the 4.7 µH inductance and shielded surface mount requirements. However, it has reduced current rating (8 A vs. 8.5 A), reduced saturation current (8 A vs. 15 A), and narrower operating temperature range (-20°C to 120°C vs. -55°C to 125°C). This part is suitable only for applications with lower current demands and warmer operating environments.

Q: Does SRP1038A-4R7M include any additional certifications?

A: Yes. SRP1038A-4R7M carries AEC-Q200 automotive qualification, indicating compliance with automotive reliability standards. This certification is not present on other substitute parts listed. Applications requiring automotive-grade components should specify SRP1038A-4R7M.

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

A: Both packaging formats are suitable for automated assembly. Tape & Reel (TR) provides continuous reel format for high-volume production. Cut Tape (CT) & Digi-Reel provides flexibility for lower-volume or mixed-component orders. Electrical and mechanical specifications are identical; packaging choice depends on production volume and inventory management requirements.
