Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 8102 is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance value: 2.5 mH @ 1 kHz
• Line configuration: 2-line common mode choke
• Current rating: 2.4A maximum
• DC resistance: 90mOhm maximum
• Operating temperature range: -55°C ~ 105°C
• Physical dimensions: 0.760" L x 0.425" W, 0.900" maximum height
• Package configuration: Vertical, 4 PC pin through-hole

The Bourns 8102-RC meets all specified electrical and mechanical parameters and serves as a direct substitute. The primary distinction between the main part and substitute is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 8102-RC is the direct equivalent substitute for the obsolete Bourns 8102. Both components share identical electrical specifications and physical dimensions, ensuring pin-for-pin compatibility in through-hole PCB applications.

The 8102-RC offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the 8102-RC meets ROHS3 compliance requirements, whereas the original 8102 is non-compliant. For new designs or production requiring regulatory compliance, the 8102-RC is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 8102-RC directly replace the Bourns 8102 in existing designs?

A: Yes. The 8102-RC is electrically and mechanically equivalent to the 8102. Both components feature identical inductance (2.5 mH @ 1 kHz), current rating (2.4A), DC resistance (90mOhm), operating temperature range (-55°C ~ 105°C), and physical dimensions (0.760" L x 0.425" W, 0.900" height). The 4-pin vertical through-hole package configuration is identical, enabling direct PCB substitution without layout modifications.

Q: What is the primary difference between the 8102 and 8102-RC?

A: The 8102 is classified as obsolete with RoHS non-compliant status. The 8102-RC is an active product meeting ROHS3 compliance standards. Both parts are functionally equivalent for EMI filtering applications.

Q: Are there packaging differences between these parts?

A: The 8102 is supplied in standard packaging, while the 8102-RC is supplied in bulk packaging. Both maintain identical component specifications and through-hole pin configuration.

Q: What applications are suitable for the Bourns 8102 / 8102-RC?

A: These common mode chokes are designed for two-conductor EMI filtering applications in equipment operating within the -55°C to 105°C temperature range and requiring 2.4A maximum current handling capacity.
