Pulse Electronics B2013 Common Mode Choke - Equivalent & Substitute Parts

Part Overview

The Pulse Electronics B2013 is a 2-line common mode choke (CMC) designed for signal line filtering in surface mount applications. This component features 9 mH inductance at 100 kHz with a maximum current rating of 100 mA and 1 Ohm DC resistance. The B2013 is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. Active substitute parts maintain identical electrical and mechanical specifications while offering current availability and compliance certifications.

Engineering Selection Recommendations

Both B2013FNL and B2013NL are direct functional equivalents to the obsolete B2013. Selection between these active alternatives is based on product status and compliance certifications:

B2013FNL and B2013NL are both classified as active products with current manufacturing availability. Both parts are ROHS3 compliant and carry EAR99 export classification. The electrical and mechanical specifications are identical across all three part numbers, ensuring direct substitution without circuit redesign or PCB layout modification.

Current inventory levels support both alternatives: B2013FNL (994 pcs) and B2013NL (992 pcs) are available as new original stock. Both parts are supplied in tube packaging and meet REACH compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can B2013FNL and B2013NL be used interchangeably with the B2013?

A: Yes. Both B2013FNL and B2013NL meet all electrical and mechanical specifications of the B2013. Inductance, current rating, DC resistance, operating temperature range, physical dimensions, and package configuration are identical. Direct substitution is possible without circuit modification.

Q: What is the primary difference between B2013FNL and B2013NL?

A: Both parts are active products with identical electrical and mechanical parameters. The difference lies in packaging designation and part number suffix. Both are supplied in tube packaging and are ROHS3 compliant.

Q: Why is the B2013 classified as obsolete?

A: The B2013 is no longer in active production. B2013FNL and B2013NL represent the current active alternatives from Pulse Electronics with identical specifications.

Q: Are there any compliance differences between the B2013 and its substitutes?

A: Yes. B2013FNL and B2013NL are ROHS3 compliant with EAR99 export classification. The original B2013 compliance status is not specified in the available data. Both active alternatives meet current regulatory requirements.

Q: Can these parts be used in applications requiring higher current ratings?

A: No. All three part numbers are rated for a maximum of 100 mA. Applications requiring higher current must use a different component.

Q: What is the moisture sensitivity level for these parts?

A: All three part numbers carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
