104CDMCCDS-R80MC Equivalent & Substitute Parts

Part Overview

The 104CDMCCDS-R80MC is a fixed surface mount inductor manufactured by Sumida America Components Inc. This shielded molded inductor is rated for 800 nH inductance with a maximum DC resistance of 3 mOhm and supports continuous current up to 23 A. The component operates across the industrial temperature range of -55°C to 125°C and is RoHS3 compliant. As an active product with 954 units in stock, substitute parts are identified to provide design flexibility, inventory alternatives, or performance optimization in applications where the primary part may be unavailable or where enhanced electrical characteristics are beneficial.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 104CDMCCDS-R80MC is determined by the following critical parameters:

Inductance Value: The substitute part must operate within the ±20% tolerance band established for the primary part. The 104CDMCCDS-R80MC specifies 800 nH; therefore, acceptable substitutes range from 640 nH to 960 nH at the 100 kHz test frequency.

Current Rating: The substitute must support the continuous current requirement of the application. The primary part is rated for 23 A continuous current with a saturation current (Isat) of 32 A.

DC Resistance (DCR): The substitute must maintain DC resistance characteristics compatible with the thermal and efficiency requirements of the circuit. The primary part specifies a maximum DCR of 3 mOhm.

Shielding: Both the primary and substitute parts are shielded molded inductors, which is a mandatory requirement for electromagnetic compatibility in the target application.

Operating Temperature Range: The substitute must support the full industrial temperature range of -55°C to 125°C.

Mounting and Package Type: Both parts are surface mount molded inductors with nonstandard package dimensions. Physical dimensions and height must be compatible with the PCB layout and assembly process.

Compliance: RoHS3 compliance and MSL rating of 1 are required for the substitute part.

The IHLP4040DZERR78M11 from Vishay Dale meets these substitution criteria with an inductance of 780 nH (within tolerance), a current rating of 27 A (exceeds requirement), and a DCR of 1.9 mOhm (superior to primary part specification).

Engineering Selection Recommendations

Primary Part Selection: The 104CDMCCDS-R80MC remains the specified component for applications where the exact inductance value of 800 nH and the saturation current of 32 A are critical design parameters. This part is active, RoHS3 compliant, and maintains MSL 1 rating for unlimited shelf life.

Substitute Part Selection: The IHLP4040DZERR78M11 is suitable for applications where the following conditions are met:

The inductance value of 780 nH falls within the ±20% tolerance band of the primary part specification (640–960 nH range), making it electrically compatible for circuits designed around the 800 nH nominal value.

The substitute part provides superior DC resistance performance at 1.9 mOhm maximum, compared to the primary part's 3 mOhm maximum. This results in lower resistive losses and reduced thermal dissipation in the inductor.

The substitute part supports a continuous current rating of 27 A, which exceeds the primary part's 23 A rating. However, the saturation current (Isat) of the substitute is 22 A, which is lower than the primary part's 32 A. Applications operating near or above 22 A saturation current must use the primary part.

Physical dimensions of the substitute part (10.80 mm × 10.16 mm × 4.00 mm) are slightly smaller than the primary part (11.50 mm × 10.00 mm × 4.00 mm), requiring PCB layout verification to ensure footprint compatibility.

Both parts are RoHS3 compliant, active products with MSL 1 rating, and operate across the full industrial temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the IHLP4040DZERR78M11 be used as a direct replacement for the 104CDMCCDS-R80MC?

A: The IHLP4040DZERR78M11 is electrically compatible for most applications. The inductance difference of 20 nH (780 nH vs. 800 nH) is within the ±20% tolerance specification. However, the lower saturation current (22 A vs. 32 A) must be evaluated against the application's peak current requirements. Physical dimensions differ slightly, requiring PCB footprint verification.

Q: What is the inductance tolerance range for both parts?

A: Both the 104CDMCCDS-R80MC and IHLP4040DZERR78M11 specify ±20% inductance tolerance at 100 kHz test frequency. For the primary part, this yields a range of 640–960 nH. For the substitute, the range is 624–936 nH. The nominal values (800 nH and 780 nH respectively) fall within each other's tolerance bands.

Q: How do the DC resistance values compare?

A: The primary part specifies a maximum DC resistance of 3 mOhm, while the substitute part specifies 1.9 mOhm maximum. The substitute offers lower resistive losses, which reduces I²R heating and improves efficiency in high-current applications.

Q: Are there any temperature or compliance differences between the two parts?

A: Both parts operate across the identical temperature range of -55°C to 125°C. Both are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. No compliance or environmental differences exist.

Q: What is the critical difference in current ratings?

A: The primary part is rated for 23 A continuous current with 32 A saturation current. The substitute is rated for 27 A continuous current but only 22 A saturation current. For applications requiring sustained currents above 22 A or peak currents above 22 A, the primary part must be used to avoid inductor saturation and performance degradation.

Q: Do the physical dimensions affect PCB design?

A: The primary part measures 11.50 mm (L) × 10.00 mm (W) × 4.00 mm (H). The substitute measures 10.80 mm (L) × 10.16 mm (W) × 4.00 mm (H). The height is identical, but length and width differ slightly. PCB footprint and component placement must be verified to ensure the substitute fits within the allocated space.

Q: What is the packaging format for both parts?

A: Both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes. Both are surface mount components with nonstandard package designations (primary: Nonstandard; substitute: 4040).
