ALFT-03A-6 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The ALFT-03A-6 is a 10 mH, 2-line common mode choke manufactured by Abracon LLC, designed for power line filtering applications in through-hole configurations. This component is classified as Active product status with full RoHS3 compliance. Substitute parts may be required due to inventory constraints, application-specific current or inductance requirements, or packaging format preferences while maintaining electrical and mechanical compatibility within the ALFT-03A series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the ALFT-03A series is determined by the following critical parameters:

• Series Compatibility: All substitute parts must belong to the ALFT-03A series
• Mounting Type: Through-hole configuration required
• Number of Lines: 2-line common mode choke topology
• Voltage Rating: Minimum 250 V DC
• Operating Temperature Range: -25°C ~ 85°C
• Physical Dimensions: 0.941" L x 0.709" W x 0.850" H maximum
• Package Configuration: Vertical, 4 PC Pin
• Compliance: RoHS3 compliant, REACH unaffected

The ALFT-03A-7 qualifies as a parametric equivalent within these constraints. Variations in inductance (10 mH vs. 7 mH) and current rating (700 mA vs. 800 mA) are permissible when application requirements allow, provided all other electrical and mechanical parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

Both ALFT-03A-6 and ALFT-03A-7 are Active product status components with identical RoHS3 and REACH compliance certifications. Selection between these parts is based on application-specific electrical requirements:

• ALFT-03A-6: Select when 10 mH inductance at 1 kHz is required and circuit current does not exceed 700 mA
• ALFT-03A-7: Select when 7 mH inductance at 1 kHz is acceptable and circuit current reaches up to 800 mA

Both parts share identical DC resistance (800 mOhm maximum), voltage rating (250 V DC), operating temperature range (-25°C ~ 85°C), and physical footprint. Packaging format differs (Bulk vs. Tray); verify packaging requirements for procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ALFT-03A-7 replace ALFT-03A-6 in all applications?

A: ALFT-03A-7 is a parametric equivalent only when the application circuit current requirement is within 800 mA and the lower inductance value of 7 mH @ 1 kHz is acceptable. If the circuit requires exactly 10 mH inductance, ALFT-03A-7 is not suitable.

Q: Are the physical dimensions identical between ALFT-03A-6 and ALFT-03A-7?

A: Yes. Both parts have identical dimensions of 0.941" L x 0.709" W x 0.850" H maximum and use the same Vertical, 4 PC Pin package configuration. PCB layout and mounting hole spacing are interchangeable.

Q: What is the difference in packaging between these parts?

A: ALFT-03A-6 is supplied in Bulk packaging, while ALFT-03A-7 is supplied in Tray packaging. Both are suitable for through-hole assembly; verify packaging format compatibility with your procurement and assembly workflow.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ALFT-03A-6 and ALFT-03A-7 are RoHS3 compliant, REACH unaffected, with MSL rating of 1 (Unlimited). Both are classified as Active product status.

Q: What is the maximum DC resistance for both parts?

A: Both parts have a maximum DC resistance of 800 mOhm, ensuring identical power dissipation characteristics at rated current.
