104CDMCDDS-4R7MC Equivalent & Substitute Parts

Part Overview

The 104CDMCDDS-4R7MC is a 4.7 µH shielded molded inductor manufactured by Sumida America Components Inc., rated for 9.5 A continuous current with a maximum DC resistance of 18mOhm. This surface mount component operates across the temperature range of -55°C to 125°C and is classified as Active product status with ROHS3 compliance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances. The primary substitute for this inductor is the IHLP4040DZER4R7M01 from Vishay Dale, which maintains the same inductance value, current rating, and operating temperature range while offering improved DC resistance characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the 104CDMCDDS-4R7MC is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Parameters (Non-Negotiable):

• Inductance value of 4.7 µH with ±20% tolerance
• Continuous current rating of 9.5 A or greater
• Operating temperature range of -55°C to 125°C or broader
• Shielded construction for EMI containment
• DC resistance within acceptable limits for thermal performance

Mechanical Parameters (Non-Negotiable):

• Surface mount technology for automated assembly
• Nonstandard package classification
• Physical dimensions compatible with PCB layout constraints
• Height-seated maximum of 0.157" (4.00mm) or less

Compliance Parameters:

• ROHS3 compliance status
• Moisture Sensitivity Level (MSL) of 1 or equivalent

The IHLP4040DZER4R7M01 from Vishay Dale satisfies all substitution criteria through matching inductance, current rating, temperature range, shielding, and compliance requirements. The substitute part demonstrates improved DC resistance performance at 16.5mOhm maximum, which is superior to the 18mOhm specification of the primary part.

Engineering Selection Recommendations

Primary Part: 104CDMCDDS-4R7MC

The 104CDMCDDS-4R7MC remains the specified component when original manufacturer continuity and exact DC resistance specifications are required. This part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory adherence.

Substitute Part: IHLP4040DZER4R7M01

The IHLP4040DZER4R7M01 is a direct electrical and mechanical substitute that provides equivalent or superior performance across all critical parameters. This Vishay Dale component offers the following advantages:

• Improved saturation current rating (17 A versus 15.3 A) provides additional design margin
• Superior DC resistance specification (16.5 mOhm versus 18 mOhm maximum) reduces power dissipation and thermal load
• Identical inductance, current rating, temperature range, and shielding characteristics
• Full ROHS3 compliance and MSL 1 rating
• Compatible nonstandard package dimensions and surface mount configuration

Both parts are Active status products with established supply chains. Selection between the primary and substitute part should be based on availability, cost considerations, and specific thermal performance requirements of the application. The substitute part's lower DC resistance makes it suitable for applications where power dissipation minimization is a design priority.

Frequently Asked Questions (FAQ)

Q: Can the IHLP4040DZER4R7M01 be used as a direct replacement for the 104CDMCDDS-4R7MC?

A: Yes. Both inductors share identical inductance (4.7 µH), current rating (9.5 A), tolerance (±20%), operating temperature range (-55°C to 125°C), shielding, and mounting type. The substitute part meets or exceeds all electrical specifications and maintains compatible physical dimensions and compliance certifications.

Q: What is the difference in DC resistance between these two parts?

A: The 104CDMCDDS-4R7MC has a maximum DC resistance of 18 mOhm, while the IHLP4040DZER4R7M01 has a maximum of 16.5 mOhm. The lower resistance in the substitute part results in reduced power dissipation and lower operating temperature under the same current conditions.

Q: Are the physical dimensions compatible for PCB layout?

A: Yes. Both parts are classified as nonstandard package types with identical height-seated specifications of 0.157" (4.00mm). The primary part measures 0.453" L x 0.394" W (11.50mm x 10.00mm), while the substitute measures 0.425" L x 0.400" W (10.80mm x 10.16mm). These dimensions are sufficiently similar for standard PCB layout compatibility, though physical verification is recommended for space-constrained designs.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 104CDMCDDS-4R7MC and IHLP4040DZER4R7M01 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). Both carry EAR99 ECCN classification. The substitute part includes REACH Unaffected status, providing additional regulatory documentation.

Q: What is the saturation current difference, and does it matter for my application?

A: The 104CDMCDDS-4R7MC has a saturation current (Isat) of 15.3 A, while the IHLP4040DZER4R7M01 has 17 A. Saturation current defines the maximum current before inductance begins to degrade significantly. The substitute part's higher saturation current provides additional design margin for transient current conditions or future design modifications.

Q: Can I use either part interchangeably in my existing design?

A: Both parts are electrically and mechanically compatible for the specified 9.5 A continuous current application. However, physical board layout should be verified due to minor dimensional differences. The substitute part's superior DC resistance and saturation current characteristics make it suitable for applications requiring enhanced thermal performance or current margin.

Q: What packaging options are available for these parts?

A: Both parts are available in Cut Tape (CT) packaging. The substitute part (IHLP4040DZER4R7M01) additionally offers Digi-Reel® packaging option, providing flexibility for different procurement and assembly workflows.
