Key Parameters

Substitute Part Grouping Explanation

Substitution of the FE2X39-5-2 is determined by the following critical electrical and mechanical parameters:

• Number of Lines: Must be 2-line configuration
• Current Rating: Minimum 700mA capability
• DC Resistance: Maximum 1.3Ohm to 1.4Ohm range
• Voltage Rating - AC: Minimum 250V
• Mounting Type: Through-hole configuration required
• Package / Case: Vertical, 4-pin configuration
• Physical Dimensions: Compatible footprint within specified length, width, and height tolerances
• Operating Temperature: Functional overlap within specified range

The SS26V-070510 manufactured by KEMET meets these substitution criteria as a 2-line common mode choke with identical current rating, compatible DC resistance, matching voltage rating, and equivalent through-hole vertical pin configuration.

Parameter Comparison

Engineering Selection Recommendations

The SS26V-070510 serves as a direct functional substitute for the obsolete FE2X39-5-2. Both components share identical electrical specifications for current rating (700mA) and voltage rating (250V AC), with DC resistance values within 0.1Ohm variance. Physical dimensions are comparable, with height specifications differing by only 0.04mm, ensuring PCB layout compatibility.

The SS26V-070510 offers the advantage of active product status and full RoHS3 compliance with REACH unaffected designation, providing regulatory continuity for new designs and ongoing production. The operating temperature range of the SS26V-070510 (-25°C ~ 120°C) covers the majority of the FE2X39-5-2 range, with the exception of the lower temperature extreme (-40°C). Applications requiring operation below -25°C require thermal performance verification.

Frequently Asked Questions (FAQ)

Q: Can the SS26V-070510 be used as a direct replacement for the FE2X39-5-2 in existing designs?

A: Yes. Both components are 2-line common mode chokes with 700mA current rating, 250V AC voltage rating, and vertical 4-pin through-hole configuration. Physical dimensions are compatible for standard PCB layouts. Verify operating temperature requirements if the application requires operation below -25°C.

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

A: The FE2X39-5-2 has a maximum DC resistance of 1.3Ohm, while the SS26V-070510 has a maximum of 1.4Ohm. This 0.1Ohm difference is within acceptable tolerance for common mode choke applications and does not affect functional compatibility.

Q: Are there compliance differences between the two parts?

A: The SS26V-070510 is RoHS3 compliant and REACH unaffected, while the FE2X39-5-2 has vendor-undefined compliance status. For new designs or applications with regulatory requirements, the SS26V-070510 provides documented compliance assurance.

Q: What is the inductance specification of the SS26V-070510?

A: The SS26V-070510 is specified at 51 mH @ 1 kHz. This parameter was not provided for the FE2X39-5-2 in the available documentation.

Q: Are the physical dimensions identical?

A: Dimensions are comparable but not identical. The FE2X39-5-2 measures 1.079" L x 0.724" W with 1.197" height, while the SS26V-070510 measures 1.024" L x 0.807" W with 1.201" height. Both fit standard through-hole PCB layouts with vertical pin orientation.
