HCM1104-R90-R Equivalent & Substitute Parts

Part Overview

The HCM1104-R90-R is a 900 nH shielded drum core wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is rated for 22 A continuous current with a maximum DC resistance of 2.5 mOhm and operates across the temperature range of -55°C to 125°C. The part is RoHS compliant and currently active in production with inventory availability of 1426 pieces.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter tolerances for this inductor category, particularly when the main part faces supply constraints or when alternative packaging configurations are required for specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCM1104-R90-R are identified based on the following electrical and mechanical criteria:

Primary Substitution Parameters:

• Inductance value within ±20% tolerance band
• Current rating equal to or greater than 22 A
• DC resistance (DCR) at or below 2.5 mOhm maximum
• Shielded construction
• Surface mount configuration
• Operating temperature range of -55°C to 125°C minimum
• RoHS compliance status

The substitute parts listed (IHLP4040DZER1R0M01 and IHLP4040DZER1R0M11) are Vishay Dale molded inductors that operate at 1 µH inductance. While the inductance value differs from the main part, these components are cross-referenced in the original substitute list and share compatible electrical characteristics within the allowed parameter envelope for this product category. Both parts maintain shielded construction, surface mount packaging, and the required temperature operating range.

Parameter Comparison

Engineering Selection Recommendations

IHLP4040DZER1R0M11 Selection Criteria:

The IHLP4040DZER1R0M11 provides the closest electrical match to the HCM1104-R90-R. This part maintains identical DC resistance (2.5 mOhm maximum), exceeds the current rating requirement at 25 A, and operates within the same temperature envelope. Both parts carry active product status and meet RoHS3 compliance. Physical dimensions are comparable with marginal differences in length and width (0.425" x 0.400" versus 0.437" x 0.394"), and both maintain 4.00mm maximum seated height. Inventory availability for this substitute is 6695 pieces.

IHLP4040DZER1R0M01 Selection Criteria:

The IHLP4040DZER1R0M01 is an alternative substitute with higher inventory availability (18254 pieces). This part operates at 17.5 A continuous current, which is below the 22 A rating of the main part. However, it provides higher saturation current (36 A) and maintains shielded construction with identical temperature range and RoHS3 compliance. The DC resistance specification of 4.1 mOhm exceeds the 2.5 mOhm maximum of the main part. This substitute is suitable only when application current requirements do not exceed 17.5 A and when the higher DCR is acceptable for the circuit design.

Both substitute parts are packaged in Cut Tape (CT) & Digi-Reel® format, differing from the main part's Tape & Reel (TR) packaging.

Frequently Asked Questions (FAQ)

Q: Can IHLP4040DZER1R0M01 directly replace HCM1104-R90-R in all applications?

A: No. The IHLP4040DZER1R0M01 has a continuous current rating of 17.5 A, which is below the 22 A requirement of the main part. Additionally, its DC resistance of 4.1 mOhm exceeds the 2.5 mOhm maximum specification. This substitute is only suitable for applications where the actual operating current does not exceed 17.5 A and where the higher resistance is acceptable.

Q: What are the key differences between the two substitute parts?

A: The IHLP4040DZER1R0M11 matches the main part's DC resistance at 2.5 mOhm and exceeds its current rating at 25 A, making it the preferred substitute. The IHLP4040DZER1R0M01 offers higher inventory availability but has lower current rating (17.5 A) and higher DC resistance (4.1 mOhm). Both maintain identical operating temperature range, shielding, and RoHS compliance.

Q: Are there packaging differences between the main part and substitutes?

A: Yes. The HCM1104-R90-R is supplied in Tape & Reel (TR) packaging, while both Vishay Dale substitutes are supplied in Cut Tape (CT) & Digi-Reel® format. Physical dimensions are comparable, with the main part measuring 0.437" L x 0.394" W and the substitutes measuring 0.425" L x 0.400" W. All three parts maintain 4.00mm maximum seated height.

Q: Do the substitute parts meet the same compliance standards?

A: Both substitute parts carry ROHS3 compliance, which exceeds the RoHS compliance of the main part. All three parts have Moisture Sensitivity Level 1 (Unlimited) and operate across -55°C to 125°C. Both substitutes are active products with current manufacturing status.

Q: What is the inductance difference between the main part and substitutes?

A: The HCM1104-R90-R operates at 900 nH, while both substitute parts operate at 1 µH. This represents approximately an 11% increase in inductance value. Both the main part and substitutes carry ±20% inductance tolerance, which allows for this variation within the acceptable parameter envelope for this product category.
