Substitute Part Grouping Explanation

Substitute parts for the ELF-15N030A are qualified based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Number of Lines: 2 (mandatory match)
• Current Rating (Max): 3A (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Package / Case: Vertical, 4 PC Pin (mandatory match)
• DC Resistance (DCR): Within acceptable operating range for power line filtering

Substitute Classification:

Direct Manufacturer Substitute: SS11VL-30006 (KEMET) meets all core compatibility criteria with 3A current rating, 2-line configuration, through-hole mounting, and vertical 4-pin package. DCR specification of 60mOhm is within acceptable tolerance for this application class.

Similar Manufacturer Substitute: B82722J2302N001 (EPCOS - TDK Electronics) meets all core compatibility criteria with 3A current rating, 2-line configuration, through-hole mounting, and vertical 4-pin package. DCR specification of 56mOhm (Typ) is within acceptable tolerance for this application class.

Engineering Selection Recommendations

SS11VL-30006 (KEMET) is the direct manufacturer substitute, offering active product status and ROHS3 compliance. This part provides equivalent electrical performance with 60mOhm DCR and maintains the required 3A current rating and 2-line configuration. The part is currently in active production with 1079 units in stock. Physical dimensions differ slightly from the original, requiring PCB layout verification for board-level integration.

B82722J2302N001 (EPCOS - TDK Electronics) is the similar manufacturer substitute, offering active product status, ROHS3 compliance, and additional regulatory approvals (ENEC, UR, VDE). This part provides equivalent electrical performance with 56mOhm (Typ) DCR and maintains the required 3A current rating and 2-line configuration. The part is currently in active production with 1043 units in stock. Physical dimensions differ from the original, requiring PCB layout verification for board-level integration. Extended operating temperature range (-40°C ~ 125°C) provides broader environmental compatibility compared to the direct substitute.

Both substitute parts address the obsolescence of the ELF-15N030A while meeting core electrical and mechanical requirements. Selection between substitutes depends on specific application requirements regarding physical footprint, temperature range, and regulatory certifications.

Frequently Asked Questions (FAQ)

Q: What makes SS11VL-30006 and B82722J2302N001 suitable substitutes for ELF-15N030A?

A: Both parts meet the mandatory compatibility criteria: 2-line configuration, 3A current rating, through-hole mounting, and vertical 4-pin package. DC resistance values (60mOhm and 56mOhm respectively) fall within acceptable operating ranges for common mode choke applications in this current class.

Q: Are there physical footprint differences between the main part and substitutes?

A: Yes. The ELF-15N030A measures 0.591" L x 0.894" W (15.00mm x 22.70mm). SS11VL-30006 measures 0.866" L x 0.571" W (22.00mm x 14.50mm), and B82722J2302N001 measures 0.917" L x 0.634" W (23.30mm x 16.10mm). PCB layout verification is required before implementation.

Q: What is the difference between the "Direct" and "Similar" substitute classifications?

A: Direct substitutes are from the same manufacturer family with closer electrical specifications. Similar substitutes meet all core compatibility criteria but may originate from different manufacturers or product lines. Both are functionally equivalent for this application.

Q: Does the RoHS compliance difference affect substitution?

A: The ELF-15N030A is RoHS non-compliant, while both substitutes are ROHS3 compliant. For new designs or applications with RoHS requirements, the substitute parts provide regulatory compliance. For legacy systems, this difference may not impact functionality but should be evaluated against procurement and environmental standards.

Q: Which substitute offers the broader operating temperature range?

A: B82722J2302N001 operates from -40°C ~ 125°C, compared to SS11VL-30006 at -25°C ~ 120°C. For applications requiring extended temperature performance, B82722J2302N001 is the appropriate selection.

Q: Are both substitutes currently available?

A: Yes. SS11VL-30006 has 1079 units in stock, and B82722J2302N001 has 1043 units in stock, both listed as active products.
