Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAV-0.5-47 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Talema Group LLC
• Series: CA
• Filter Type: Signal Line
• Number of Lines: 2
• Current Rating (Max): 500mA
• Voltage Rating - AC: 250V
• Operating Temperature Range: -40°C ~ 125°C
• Mounting Type: Through Hole
• Package / Case: Vertical, 4 PC Pin
• RoHS Status: ROHS3 Compliant

Variable Parameters (Allowed Variance):

• Inductance @ Frequency: Different inductance values within the CA series
• DC Resistance (DCR): Varies with inductance rating
• Physical Dimensions: Varies with inductance rating

The CAV-0.5-27 qualifies as a parametric equivalent because it maintains all mandatory matching parameters while offering a lower inductance value of 27 mH @ 10 kHz with correspondingly reduced DC resistance of 1.179Ohm.

Parameter Comparison

Engineering Selection Recommendations

Both the CAV-0.5-47 and CAV-0.5-27 maintain Active product status within the Talema Group LLC CA series and are ROHS3 compliant. Selection between these parts depends on the specific inductance requirement of the application circuit. The CAV-0.5-47 provides 47 mH inductance with 1.39Ohm DCR, while the CAV-0.5-27 provides 27 mH inductance with 1.179Ohm DCR. Both parts support identical current ratings (500mA), voltage ratings (250V AC), operating temperature ranges (-40°C to 125°C), and mounting configurations (through-hole, vertical 4-pin package). The reduced physical dimensions of the CAV-0.5-27 may provide layout advantages in space-constrained applications where lower inductance values are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the CAV-0.5-27 be used as a direct replacement for the CAV-0.5-47?

A: The CAV-0.5-27 is a parametric equivalent within the CA series but provides different inductance (27 mH versus 47 mH). Direct substitution is only valid if the application circuit design permits operation with 27 mH inductance. Both parts share identical current, voltage, temperature, and mounting specifications.

Q: What are the physical dimension differences between these parts?

A: The CAV-0.5-47 measures 0.906" L x 0.610" W x 0.984" H (23.00mm x 15.50mm x 25.00mm). The CAV-0.5-27 measures 0.701" L x 0.504" W x 0.787" H (17.80mm x 12.80mm x 20.00mm). The smaller footprint of the CAV-0.5-27 reflects its lower inductance rating.

Q: Are both parts RoHS compliant?

A: Yes, both the CAV-0.5-47 and CAV-0.5-27 are ROHS3 compliant and maintain identical environmental compliance certifications.

Q: What is the difference in DC resistance between these parts?

A: The CAV-0.5-47 has a maximum DC resistance of 1.39Ohm, while the CAV-0.5-27 has a maximum DC resistance of 1.179Ohm. The lower resistance of the CAV-0.5-27 corresponds to its lower inductance value.

Q: Do both parts support the same current and voltage ratings?

A: Yes, both parts are rated for 500mA maximum current and 250V AC voltage. Operating temperature ranges are identical at -40°C to 125°C.
