CM6296-204 Equivalent & Substitute Parts Reference

Part Overview

The CM6296-204 is a 2-line common mode choke (CMC) surface mount inductor manufactured by API Delevan Inc. This component operates at 200 µH inductance at 1 kHz with a maximum current rating of 8.5A and DC resistance of 16 mOhm. The part is classified as Active product status and is currently in stock with 723 pieces available.

Substitute parts are necessary when the CM6296-204 becomes unavailable, when design requirements permit alternative inductance values, or when improved compliance specifications are required. The CM6296R series provides parametric alternatives within the same physical package and mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CM6296-204 is determined by the following critical parameters:

Mechanical Compatibility:

• Mounting type must be Surface Mount
• Physical dimensions must match: 1.058" L x 1.058" W (26.87mm x 26.87mm)
• Height must not exceed 0.423" (10.74mm)
• Package configuration must be Horizontal, 4 PC Pad

Electrical Compatibility:

• Number of lines must remain 2 (2-line common mode choke configuration)
• Operating temperature range must be -55°C ~ 125°C
• Moisture sensitivity level must be 5A (24 Hours)

Functional Parameters:

• Inductance value at 1 kHz may vary based on application requirements
• Current rating and DC resistance are interdependent and may vary across the CM6296R series
• All substitute parts must maintain the same ECCN (EAR99) and HTSUS (8548.00.0000) classifications

The three substitute parts listed (CM6296R-154, CM6296R-253, CM6296R-503) meet all mechanical and electrical compatibility criteria while offering different inductance and current rating combinations.

Parameter Comparison

Engineering Selection Recommendations

CM6296R-154 (150 µH @ 1 kHz): This substitute provides 75% of the inductance value of the CM6296-204 with improved current handling (9.5A vs. 8.5A) and identical DC resistance. The CM6296R-154 is ROHS3 compliant, addressing regulatory requirements where the original CM6296-204 does not. This part is suitable for applications where lower inductance values are acceptable and enhanced compliance is required.

CM6296R-253 (25 µH @ 1 kHz): This substitute provides significantly lower inductance (12.5% of the CM6296-204 value) with the highest current rating (10A) and lowest DC resistance (14 mOhm). The CM6296R-253 is ROHS3 compliant. This part is applicable only to designs requiring minimal inductance filtering with maximum current capacity.

CM6296R-503 (50 µH @ 1 kHz): This substitute provides 25% of the inductance value of the CM6296-204 with maximum current rating (10A) and reduced DC resistance (14 mOhm). The CM6296R-503 is ROHS3 compliant. This part is suitable for applications requiring moderate inductance filtering with improved thermal performance.

All substitute parts maintain identical mechanical compatibility, operating temperature range, and moisture sensitivity specifications. The primary differentiators are inductance value, current rating, DC resistance, and RoHS compliance status.

Frequently Asked Questions (FAQ)

Q: Can CM6296R-154 directly replace CM6296-204 in my circuit?

A: Direct replacement is possible only if your circuit design permits operation at 150 µH inductance instead of 200 µH. The mechanical footprint, mounting configuration, and operating temperature range are identical. Verify that the 9.5A current rating meets or exceeds your application requirements.

Q: What is the primary difference between CM6296-204 and the CM6296R series?

A: The CM6296-204 is RoHS non-compliant, while all CM6296R series parts (CM6296R-154, CM6296R-253, CM6296R-503) are ROHS3 compliant. The CM6296R series also offers different inductance values and improved current ratings in some configurations.

Q: Are all substitute parts available in the same package?

A: Yes. All parts listed—CM6296-204, CM6296R-154, CM6296R-253, and CM6296R-503—use identical Surface Mount packaging with Horizontal, 4 PC Pad configuration and matching physical dimensions of 1.058" L x 1.058" W (26.87mm x 26.87mm).

Q: Which substitute part has the lowest DC resistance?

A: Both CM6296R-253 and CM6296R-503 have DC resistance of 14 mOhm, compared to 16 mOhm for the CM6296-204 and CM6296R-154. Lower DC resistance reduces power dissipation in high-current applications.

Q: Can I use CM6296R-253 if I need 200 µH inductance?

A: No. The CM6296R-253 provides only 25 µH inductance, which is insufficient for applications requiring 200 µH filtering. Use CM6296R-154 (150 µH) as the closest alternative, or maintain the original CM6296-204 specification.

Q: What is the moisture sensitivity level for all these parts?

A: All parts in this comparison—CM6296-204, CM6296R-154, CM6296R-253, and CM6296R-503—have identical Moisture Sensitivity Level (MSL) of 5A (24 Hours), indicating equivalent moisture handling requirements during storage and assembly.

Q: Are there any compliance differences I should consider?

A: Yes. The CM6296-204 is RoHS non-compliant, while all CM6296R substitutes are ROHS3 compliant. If your application or region requires RoHS compliance, select from the CM6296R series. All parts are REACH Unaffected and classified as EAR99 for export control purposes.
