Substitute Part Grouping Explanation

Substitution eligibility for the B82502WC2 is determined by the following critical parameters:

• Inductance Value: 82 mH @ 10 kHz (must match)
• Number of Lines: 2-line configuration (must match)
• Mounting Type: Through-hole (must match)
• Package Configuration: Horizontal, 4-pin (must match)
• Current Rating: Minimum 200 mA (equal or greater acceptable)
• Voltage Ratings: DC ≥ 600 V and AC ≥ 500 V (equal or greater acceptable)
• RoHS Compliance: ROHS3 Compliant (must match)

The B82724A2501N001 qualifies as a substitute based on matching inductance, line configuration, mounting type, and package style. The substitute offers improved electrical performance with higher current capacity (500 mA vs. 200 mA) and lower DC resistance (2.3 Ohm vs. 45 Ohm), making it suitable for applications requiring the original specifications.

Parameter Comparison

Engineering Selection Recommendations

The B82724A2501N001 is the manufacturer-recommended substitute for the obsolete B82502WC2. Both components are ROHS3 compliant and manufactured by EPCOS - TDK Electronics, ensuring design continuity and regulatory alignment.

The B82724A2501N001 maintains identical inductance and line configuration while offering superior electrical performance through reduced DC resistance and increased current capacity. The substitute carries active product status with established supply availability (1002 pcs in stock) compared to the obsolete original part (782 pcs remaining inventory).

Voltage rating consideration: The substitute is rated for 250 V AC versus the original 500 V AC specification. Applications requiring the full 500 V AC rating must evaluate this reduction against actual circuit requirements. The DC voltage rating for the substitute is not specified in available documentation.

Both components feature identical through-hole mounting and horizontal 4-pin package configuration, supporting direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the B82724A2501N001 directly replace the B82502WC2 in existing designs?

A: Direct replacement is possible for applications where the 250 V AC rating of the substitute is acceptable. The matching inductance (82 mH @ 10 kHz), line configuration (2-line), mounting type (through-hole), and package style (horizontal, 4-pin) ensure functional compatibility. Verify that your circuit does not require the original 500 V AC specification.

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

A: The primary differences are current rating (200 mA vs. 500 mA), DC resistance (45 Ohm vs. 2.3 Ohm), AC voltage rating (500 V vs. 250 V), and product status (obsolete vs. active). The substitute provides improved electrical performance with lower losses and higher current capacity.

Q: Are both parts RoHS compliant?

A: Yes, both the B82502WC2 and B82724A2501N001 are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the packaging difference between these parts?

A: The B82502WC2 is supplied in standard packaging, while the B82724A2501N001 is supplied in tray packaging. Both maintain identical component dimensions and through-hole pin configuration for PCB assembly.

Q: Why is the B82502WC2 listed as obsolete?

A: The B82502WC2 has been discontinued by the manufacturer. The B82724A2501N001 represents the active product line continuation with enhanced specifications and ongoing manufacturing support.
