CAX-1.1-6.8 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The CAX-1.1-6.8 is a 2-line common mode choke manufactured by Talema Group LLC, designed for signal line filtering applications. This through-hole component operates at 6.8 mH inductance at 10 kHz with a maximum current rating of 1.1A and DC resistance of 342 mOhm. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CAX-1.1-6.8 are identified based on the following electrical and mechanical compatibility criteria:

Electrical Parameters:

• Filter type classification (Signal Line)
• Number of lines (2-line configuration)
• Frequency reference point (10 kHz measurement standard)
• Operating temperature range (-40°C to 125°C minimum)
• AC voltage rating (250V minimum)
• Through-hole mounting compatibility

Mechanical Parameters:

• Vertical, 4-pin package configuration
• Through-hole pin layout

Compliance Parameters:

• RoHS3 compliance requirement
• Moisture sensitivity level 1 (unlimited)
• REACH unaffected status

The substitute part CAV-1.2-10 meets these criteria with allowable variations in inductance value (10 mH versus 6.8 mH), current rating (1.2A versus 1.1A), and DC resistance (285 mOhm versus 342 mOhm). These parameter variations remain within acceptable substitution tolerances for 2-line common mode choke applications in the CA series.

Parameter Comparison

Engineering Selection Recommendations

Both the CAX-1.1-6.8 and CAV-1.2-10 maintain active production status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts is determined by application-specific electrical requirements:

CAX-1.1-6.8 Selection Criteria:

• Applications requiring 6.8 mH inductance at 10 kHz
• Current loads up to 1.1A
• Higher DC resistance tolerance (342 mOhm maximum)

CAV-1.2-10 Selection Criteria:

• Applications requiring 10 mH inductance at 10 kHz
• Current loads up to 1.2A
• Lower DC resistance (285 mOhm typical)
• Larger physical footprint (23.00mm L x 15.50mm W x 15.50mm H versus 17.80mm L x 12.80mm W x 20.00mm H)

Both parts share identical operating temperature range, voltage rating, mounting configuration, and regulatory compliance status. Physical dimension differences must be verified against PCB layout constraints before substitution.

Frequently Asked Questions (FAQ)

Q: Can CAV-1.2-10 be used as a direct replacement for CAX-1.1-6.8?

A: CAV-1.2-10 is a parametric equivalent substitute, not a direct pin-for-pin replacement. Both parts feature identical 2-line through-hole configuration with vertical 4-pin package layout. However, the inductance value differs (10 mH versus 6.8 mH), current rating increases (1.2A versus 1.1A), and physical dimensions vary. Substitution is valid only when the application circuit design accommodates the higher inductance value and the PCB layout permits the larger component footprint.

Q: What are the key electrical differences between these parts?

A: The CAV-1.2-10 provides 47% higher inductance (10 mH versus 6.8 mH) and 9% higher current capacity (1.2A versus 1.1A). DC resistance is lower in the substitute part (285 mOhm typical versus 342 mOhm maximum). These differences affect filtering performance and power dissipation characteristics in the application circuit.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CAX-1.1-6.8 and CAV-1.2-10 are ROHS3 compliant with moisture sensitivity level 1 (unlimited) and REACH unaffected status.

Q: What are the physical dimension constraints?

A: CAX-1.1-6.8 measures 17.80mm L x 12.80mm W x 20.00mm H. CAV-1.2-10 measures 23.00mm L x 15.50mm W x 15.50mm H. The substitute part is larger in length and width but shorter in height. PCB layout verification is required before substitution.

Q: Do both parts operate across the same temperature range?

A: Yes. Both parts operate from -40°C to 125°C with identical AC voltage rating of 250V.
