CM6296-503 Equivalent & Substitute Parts Reference

Part Overview

The CM6296-503 is a 50 µH Common Mode Choke (CMC) with 2-line configuration, rated for 10A maximum current, manufactured by API Delevan Inc. This surface mount component operates across the temperature range of -55°C to 125°C and features a DC resistance of 14 mOhm maximum. The part is currently Active in product status and available in bulk packaging with 1085 pieces in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained within the allowed specifications for common mode choke applications. Alternative models may be required due to RoHS compliance requirements, inventory availability, or specific application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CM6296-503 are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent (Electrical & Mechanical Match): The CM6296R-503 maintains identical electrical specifications: 50 µH @ 1 kHz inductance, 10A current rating, and 14 mOhm DCR. Physical dimensions, mounting type, and thermal operating range are unchanged. The primary distinction is RoHS compliance status: CM6296R-503 is ROHS3 Compliant, whereas CM6296-503 is RoHS non-compliant.

Parametric Equivalent (Partial Electrical Match): The CM6296R-253 shares the same 2-line configuration, 10A current rating, 14 mOhm DCR, and identical physical dimensions and mounting characteristics. The inductance value differs at 25 µH @ 1 kHz (versus 50 µH for the main part). This part is ROHS3 Compliant and suitable for applications where lower inductance is acceptable within the design specification.

All substitute parts maintain the same package type (Horizontal, 4 PC Pad), MSL rating (5A, 24 Hours), and operating temperature range (-55°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

CM6296R-503 Selection Criteria: Select CM6296R-503 when RoHS3 compliance is required. This part provides direct electrical and mechanical equivalence to CM6296-503 with identical inductance (50 µH @ 1 kHz), current rating (10A), and DC resistance (14 mOhm). Both parts are Active in product status. The CM6296R-503 is ROHS3 Compliant, making it suitable for applications subject to RoHS regulations. Inventory availability is 1158 pieces.

CM6296R-253 Selection Criteria: Select CM6296R-253 when application design specifications permit 25 µH inductance instead of 50 µH. This part maintains all mechanical compatibility and shares the 10A current rating and 14 mOhm DCR with the main part. The CM6296R-253 is ROHS3 Compliant and offers 1170 pieces in inventory. This substitution is valid only when the lower inductance value meets circuit requirements.

Compliance Considerations: Both substitute parts are ROHS3 Compliant and REACH Unaffected, with identical ECCN (EAR99) and HTSUS (8548.00.0000) classifications. The original CM6296-503 is RoHS non-compliant; substitution to CM6296R series parts is necessary for applications requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can CM6296R-503 be used as a direct replacement for CM6296-503?

A: Yes. CM6296R-503 is electrically and mechanically equivalent to CM6296-503. Both parts feature 50 µH @ 1 kHz inductance, 10A current rating, 14 mOhm DCR, identical physical dimensions (1.058" L x 1.058" W, 0.423" height), and the same Horizontal 4 PC Pad package. The primary difference is RoHS compliance status: CM6296R-503 is ROHS3 Compliant.

Q: What is the difference between CM6296-503 and CM6296R-503?

A: The electrical and mechanical specifications are identical. The distinction is RoHS compliance: CM6296-503 is RoHS non-compliant, while CM6296R-503 is ROHS3 Compliant. Both parts are manufactured by API Delevan Inc. and are Active in product status.

Q: Can CM6296R-253 replace CM6296-503 in my application?

A: CM6296R-253 can replace CM6296-503 only if your circuit design accepts 25 µH inductance instead of 50 µH. All other electrical parameters match: 10A current rating, 14 mOhm DCR, and identical operating temperature range (-55°C ~ 125°C). Physical dimensions and mounting type are unchanged. Verify that the lower inductance value meets your filtering or impedance requirements before substitution.

Q: Are all substitute parts surface mount components?

A: Yes. CM6296-503, CM6296R-503, and CM6296R-253 are all surface mount components with identical package type (Horizontal, 4 PC Pad) and dimensions (1.058" L x 1.058" W, 0.423" maximum height).

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

A: All three parts share the same Moisture Sensitivity Level (MSL) rating of 5A (24 Hours).

Q: Are there any differences in operating temperature range between the parts?

A: No. All three parts operate across the identical temperature range of -55°C to 125°C.

Q: Which part should I select for a new design?

A: For new designs, select CM6296R-503 if your application requires 50 µH inductance and RoHS compliance. CM6296R-503 is ROHS3 Compliant and maintains all electrical and mechanical specifications of CM6296-503. If lower inductance is acceptable, CM6296R-253 is also ROHS3 Compliant and available.
