Substitute Part Grouping Explanation

Substitution eligibility for the LF2115NP-222 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Inductance: 2.2 mH @ 1 kHz
• Current Rating: 1.3A maximum
• DC Resistance: 240 mOhm maximum
• Number of Lines: 2-line configuration
• Filter Type: Power Line

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Through Hole
• Package Configuration: Vertical, 4 PC Pin
• Pin count and spacing compatibility

Compliance Parameters (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The LF2020NP-222 meets all electrical and compliance requirements for substitution. Physical dimensions vary (see Parameter Comparison table), but both parts maintain identical pin configuration and mounting methodology, allowing direct functional replacement in through-hole PCB applications.

Engineering Selection Recommendations

Both the LF2115NP-222 and LF2020NP-222 are Active products from Sumida America Components Inc. and carry identical electrical specifications, making them functionally equivalent for power line common mode choke applications requiring 2.2 mH inductance at 1.3A current rating.

Selection Criteria Based on Provided Data:

The primary differentiator between these parts is physical footprint. The LF2115NP-222 measures 21.00mm x 21.00mm with a maximum height of 17.00mm, while the LF2020NP-222 measures 21.00mm x 16.20mm with a maximum height of 22.50mm. PCB layout constraints and available vertical clearance determine which variant is appropriate for a given application.

Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited), indicating compatibility with standard manufacturing and storage conditions. Both carry EAR99 export classification and identical HTSUS codes.

Selection should be based on available PCB space and component placement requirements. Electrical performance and compliance certifications are equivalent across both parts.

Frequently Asked Questions (FAQ)

Q: Can the LF2020NP-222 directly replace the LF2115NP-222 in an existing design?

A: Yes, from an electrical and functional standpoint. Both parts deliver identical inductance (2.2 mH @ 1 kHz), current rating (1.3A), and DC resistance (240 mOhm). However, physical dimensions differ. The LF2020NP-222 is narrower (16.20mm vs 21.00mm width) but taller (22.50mm vs 17.00mm height). PCB layout must accommodate these dimensional changes.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, carry MSL rating 1 (Unlimited), and share identical ECCN and HTSUS classifications. Compliance requirements are fully equivalent.

Q: What determines whether these parts are substitutable?

A: Substitutability is based on matching electrical parameters (inductance, current rating, DC resistance, line count), filter type (power line), mounting method (through hole), package configuration (vertical 4-pin), and compliance status (ROHS3). All these criteria are met by both parts.

Q: Does the height difference affect electrical performance?

A: No. The height variation reflects physical package design but does not alter electrical characteristics. Inductance, current handling, and resistance remain identical.

Q: Which part should I choose for a space-constrained application?

A: If vertical clearance is limited, the LF2115NP-222 (17.00mm height) is preferable. If horizontal PCB space is constrained, the LF2020NP-222 (16.20mm width) is preferable. Electrical performance is equivalent in both cases.

Q: Are both parts currently available?

A: Both parts carry Active product status. Inventory levels differ: LF2115NP-222 has 816 pcs in stock, while LF2020NP-222 has 9269 pcs in stock.
