CM6296-104 Equivalent & Substitute Parts Reference

Part Overview

The CM6296-104 is a 2-line common mode choke (CMC) surface mount inductor manufactured by API Delevan Inc. This component operates at 100 µH inductance at 1 kHz with a maximum current rating of 9.5A and a DC resistance of 16 mOhm. The part is classified as Active product status and is available in bulk packaging with 840 pieces in current inventory.

Common mode chokes are essential filtering components in power distribution and signal integrity applications. Substitute parts become necessary when the original specification is unavailable, when design requirements change, or when alternative compliance certifications are required for specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CM6296-104 are selected based on strict parametric compatibility within the CM6296 series family. The substitution logic is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of Lines: 2 (fixed requirement)
• Mounting Type: Surface Mount (fixed requirement)
• Package / Case: Horizontal, 4 PC Pad (fixed requirement)
• Physical Dimensions: 1.058" L x 1.058" W x 0.423" H maximum (fixed requirement)
• Operating Temperature Range: -55°C ~ 125°C (fixed requirement)
• Moisture Sensitivity Level: 5A (24 Hours) (fixed requirement)

Variable Parameters Allowing Substitution:

• Inductance @ 1 kHz: 25 µH, 50 µH, 100 µH, 150 µH
• Current Rating (Max): 9.5A or 10A
• DC Resistance (Max): 14 mOhm or 16 mOhm
• RoHS Status: RoHS non-compliant or ROHS3 Compliant

All substitute parts maintain identical physical footprint, thermal characteristics, and electrical interface specifications. Differences in inductance value, current rating, and DC resistance reflect design variations within the same product family and do not affect mechanical or thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

CM6296R-154 (150 µH @ 1 kHz): This substitute maintains the same current rating (9.5A) and DC resistance (16 mOhm) as the CM6296-104. Selection of this part is appropriate when higher inductance filtering is required. The CM6296R-154 carries ROHS3 compliance certification, providing regulatory advantage over the non-compliant CM6296-104. Inventory availability is higher at 1551 pieces.

CM6296R-253 (25 µH @ 1 kHz): This substitute provides lower inductance with improved current handling (10A rating) and reduced DC resistance (14 mOhm). The CM6296R-253 is suitable for applications requiring lower impedance filtering or higher current capacity. ROHS3 compliance is included. Inventory level is 1170 pieces.

CM6296R-503 (50 µH @ 1 kHz): This substitute offers mid-range inductance (50 µH) with 10A current rating and 14 mOhm DC resistance. The CM6296R-503 bridges the performance gap between lower and higher inductance options. ROHS3 compliance certification is provided. Inventory availability is 1158 pieces.

All substitute parts share identical mechanical footprint, thermal operating range, and moisture sensitivity specifications with the CM6296-104. Selection between substitutes depends on specific inductance and current requirements of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can CM6296R-154 replace CM6296-104 in existing PCB designs?

A: Yes. Both parts maintain identical physical dimensions (1.058" L x 1.058" W x 0.423" H maximum), package configuration (Horizontal, 4 PC Pad), and mounting type (Surface Mount). PCB footprints are directly compatible. The difference in inductance value (150 µH vs. 100 µH) affects circuit filtering characteristics but not mechanical or thermal compatibility.

Q: What is the difference between CM6296-104 and CM6296R series parts?

A: The CM6296-104 belongs to the CM6296 series and is RoHS non-compliant. The CM6296R-154, CM6296R-253, and CM6296R-503 are part of the CM6296R series and carry ROHS3 compliance certification. All parts share the same physical package, thermal range, and 2-line common mode choke configuration.

Q: Can I use CM6296R-253 (25 µH) instead of CM6296-104 (100 µH)?

A: Mechanical and thermal compatibility is confirmed. However, the 75 µH inductance difference will alter circuit filtering performance. The CM6296R-253 provides higher current capacity (10A vs. 9.5A) and lower DC resistance (14 mOhm vs. 16 mOhm). Circuit simulation or testing is necessary to confirm functional equivalence for the specific application.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All parts listed (CM6296-104, CM6296R-154, CM6296R-253, CM6296R-503) are supplied in bulk packaging with identical moisture sensitivity level (5A, 24 Hours) and package configuration (Horizontal, 4 PC Pad).

Q: What is the operating temperature range for all these parts?

A: All parts operate across the identical temperature range of -55°C to 125°C. Thermal performance and reliability specifications are equivalent across the entire substitute group.

Q: Does RoHS compliance affect electrical performance?

A: RoHS compliance status reflects manufacturing process and material composition but does not alter electrical specifications. ROHS3 compliant parts (CM6296R series) and the RoHS non-compliant CM6296-104 deliver identical inductance, current rating, and DC resistance values within their respective specifications.
