CM9900-154 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The CM9900-154 is a 150 µH common mode choke manufactured by API Delevan Inc., designed for two-line filtering applications in through-hole configurations. This component operates at a maximum current rating of 2.8A with a DC resistance of 30mOhm and functions across an operating temperature range of -55°C to 125°C. The part maintains Active product status and is available in bulk packaging with 1111 pieces in current inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, allowing for component interchangeability in circuit designs where inductance values and current ratings permit functional substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CM9900-154 is determined by the following critical parameters: number of lines (2-line configuration), mounting type (through-hole), package case style (vertical, 4 PC pin), physical dimensions (0.839" L x 0.740" W x 0.669" H maximum), current rating capability (2.8A maximum), and operating temperature range (-55°C to 125°C). The CM9900-104 qualifies as a parametric equivalent because it maintains identical values across all these core mechanical and electrical compatibility criteria. The primary distinction between the main part and substitute lies in inductance value (150 µH versus 100 µH) and DC resistance (30mOhm versus 25mOhm), both of which represent lower values in the substitute part. These differences do not affect physical interchangeability or thermal/current handling capacity, making the CM9900-104 suitable for applications where the lower inductance specification is acceptable.

Engineering Selection Recommendations

Both the CM9900-154 and CM9900-104 maintain Active product status within the CM9900 series from API Delevan Inc., ensuring continued manufacturing support and availability. Component selection between these parts depends on circuit inductance requirements. The CM9900-154 provides 150 µH inductance with 30mOhm DCR, while the CM9900-104 provides 100 µH inductance with 25mOhm DCR. Both parts share identical mechanical compatibility, current handling capacity (2.8A), thermal operating range (-55°C to 125°C), and compliance status (RoHS non-compliant, REACH Unaffected). Selection should be based on the specific inductance value required by the application circuit. Both parts are suitable for through-hole PCB assembly in two-line common mode filtering applications where the specified current and temperature parameters are within design limits.

Frequently Asked Questions (FAQ)

Q: Can CM9900-104 be used as a direct replacement for CM9900-154?

A: Physical and mechanical interchangeability is confirmed. Both parts feature identical mounting type (through-hole), package configuration (vertical, 4 PC pin), dimensions (0.839" L x 0.740" W x 0.669" H), current rating (2.8A), and operating temperature range (-55°C to 125°C). Substitution is valid only if the circuit design accepts the lower inductance value of 100 µH instead of 150 µH.

Q: What are the key differences between these parts?

A: The CM9900-154 provides 150 µH inductance with 30mOhm maximum DC resistance. The CM9900-104 provides 100 µH inductance with 25mOhm maximum DC resistance. All other electrical and mechanical parameters remain identical.

Q: Are both parts suitable for the same PCB footprint?

A: Yes. Both parts share identical dimensions (0.839" L x 0.740" W) and height (0.669" maximum), vertical orientation, and 4-pin through-hole configuration. PCB layout compatibility is confirmed.

Q: What compliance considerations apply to both parts?

A: Both parts are RoHS non-compliant and REACH Unaffected. Compliance requirements must be evaluated against specific application and regional regulations.

Q: How do the current ratings compare?

A: Both parts are rated for a maximum current of 2.8A. Current handling capacity is equivalent between the two components.

Q: What is the operating temperature range for both parts?

A: Both the CM9900-154 and CM9900-104 operate across -55°C to 125°C, providing identical thermal performance specifications.
