Key Parameters

Substitute Part Grouping Explanation

The Bourns 8106-RC qualifies as a direct substitute based on the following critical parameters:

• Inductance value: 5 mH @ 1 kHz (identical)
• Number of lines: 2 (identical)
• Current rating: 3.7A (identical)
• DC resistance: 70mOhm maximum (identical)
• Mounting type: Through hole (identical)
• Physical dimensions: 1.200" L x 0.600" W, 1.200" height (identical)
• Package configuration: Vertical, 4 PC pin (identical)
• Operating temperature range: -55°C ~ 105°C (identical)
• Moisture sensitivity: MSL 1 (identical)

The 8106-RC maintains full electrical and mechanical compatibility with the 8106, differing only in product status (active vs. obsolete) and packaging format (bulk vs. standard).

Parameter Comparison

Engineering Selection Recommendations

The Bourns 8106-RC is the appropriate selection for new designs and ongoing production requiring a 5 mH, 2-line common mode choke with 3.7A capacity. The 8106-RC maintains active product status with ROHS3 compliance, providing supply chain continuity and regulatory alignment. The 8106 remains available for legacy system support where RoHS non-compliance is acceptable and existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can the 8106-RC directly replace the 8106 in existing designs? A: Yes. The 8106-RC provides identical electrical performance and mechanical fit. Both components share the same inductance (5 mH @ 1 kHz), current rating (3.7A), DC resistance (70mOhm), and physical dimensions (1.200" L x 0.600" W, 1.200" height). The primary difference is product status and RoHS compliance.

Q: What is the significance of the product status difference? A: The 8106 is classified as obsolete, indicating discontinued manufacturing. The 8106-RC is active, ensuring ongoing availability and supply chain support. For new production, the 8106-RC is the recommended selection.

Q: Are there packaging differences between these parts? A: Both components use identical through-hole, vertical 4-pin packaging. The 8106-RC is supplied in bulk packaging, while the 8106 uses standard packaging. This does not affect electrical or mechanical compatibility.

Q: Does RoHS compliance affect electrical performance? A: No. RoHS compliance relates to material composition and environmental standards, not electrical characteristics. Both the 8106 and 8106-RC deliver identical inductance, current handling, and resistance specifications.

Q: What is the operating temperature range for both parts? A: Both the 8106 and 8106-RC operate across -55°C to 105°C, providing identical thermal performance for industrial and commercial applications.
