Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FE2X15-4-2 is determined by the following critical parameters:

• Number of Lines: Must be 2-line configuration
• Current Rating (Max): Must support minimum 1A
• DC Resistance (DCR): Must not exceed 530mOhm (typical values up to 540mOhm acceptable)
• Voltage Rating - AC: Must support minimum 250V
• Operating Temperature Range: Must cover -40°C ~ 125°C
• Mounting Type: Must be Through Hole
• Package / Case: Must be Vertical, 4 PC Pin configuration
• Physical Dimensions: Must fit within or match specified envelope (23.39mm x 15.90mm x 25.40mm max height)

The B82722J2102N020 manufactured by EPCOS - TDK Electronics meets all substitution criteria within these allowed parameters.

Engineering Selection Recommendations

The B82722J2102N020 is the qualified substitute for the obsolete FE2X15-4-2 based on the following factors:

Product Status: The substitute part carries Active product status from EPCOS - TDK Electronics, ensuring long-term availability and supply chain continuity compared to the obsolete FE2X15-4-2.

Compliance & Certifications: The B82722J2102N020 holds ENEC, UR, and VDE approval certifications and is ROHS3 compliant with REACH affected status. These certifications provide regulatory compliance for applications requiring international standards adherence.

Electrical Compatibility: DC resistance of 540mOhm (typical) is within acceptable tolerance of the original 530mOhm specification. Current rating, voltage rating, and temperature operating range are identical to the main part.

Mechanical Compatibility: Physical dimensions are within acceptable tolerance (length and width variance <0.5mm, height identical). Both parts maintain identical through-hole mounting configuration and vertical 4-pin package orientation, ensuring PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the B82722J2102N020 be used as a direct replacement for FE2X15-4-2 on existing PCBs?

A: Yes. Both parts share identical mounting type (through-hole), package configuration (vertical 4-pin), and physical height (25.40mm max). Dimensional variance in length and width is less than 0.5mm, which is within standard PCB tolerance for through-hole component placement.

Q: What is the significance of the DC resistance difference (530mOhm vs 540mOhm)?

A: The 10mOhm difference represents a 1.9% variance. Both values fall within typical manufacturing tolerances for common mode chokes in this category and do not affect functional performance in standard EMI filtering applications.

Q: Why is the FE2X15-4-2 listed as obsolete?

A: Obsolete status indicates the manufacturer (Pulse Electronics) has discontinued production. The B82722J2102N020 from EPCOS - TDK Electronics provides equivalent functionality with active production status and established supply chain availability.

Q: Are there compliance differences between the two parts?

A: The B82722J2102N020 carries formal certifications (ENEC, UR, VDE) and ROHS3 compliance, whereas the FE2X15-4-2 approval agency information is not specified. For applications requiring regulatory compliance documentation, the substitute part provides documented certification support.

Q: What packaging format is the B82722J2102N020 supplied in?

A: The substitute part is supplied in Tray packaging, compared to the main part's unspecified packaging format. Tray packaging is standard for through-hole components and does not affect component functionality or PCB assembly compatibility.
