Key Parameters

Substitute Part Grouping Explanation

Substitution of the LF-215U is determined by the following critical parameters:

Voltage Compatibility: The substitute part must support the rated AC voltage of 250V minimum. The LF-215U operates at 250VAC; the substitute GTX-2160-Y22 maintains 250VAC compatibility with higher DC voltage rating (560V), ensuring safe operation in the original application.

Current Rating: The substitute must equal or exceed the 15A current requirement. The GTX-2160-Y22 provides 16A rating, meeting this criterion.

Filter Type and Phase Configuration: Both parts are single-phase EMC/EMI line filters, maintaining functional equivalence for general-purpose applications.

Mounting and Termination: Both parts feature chassis mount configuration. The LF-215U uses M4 threaded posts while the GTX-2160-Y22 uses terminal block termination. This represents a mechanical interface change requiring connector adaptation.

Regulatory Compliance: Both parts hold UL approval and ROHS3 compliance, ensuring regulatory continuity.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: GTX-2160-Y22 is the KEMET manufacturer-recommended substitute for LF-215U applications.

Electrical Suitability: The GTX-2160-Y22 meets all critical electrical parameters. The 250VAC rating matches the original specification exactly. The 16A current rating exceeds the 15A requirement, providing operational margin. The higher 560V DC rating does not compromise performance in 250V applications and enhances design robustness.

Regulatory Compliance: Both parts maintain ROHS3 compliance and UL approval. The GTX-2160-Y22 carries additional certifications (cUL, TUV), providing expanded regulatory coverage for international applications.

Operational Differences: The GTX-2160-Y22 employs single-stage filtering versus the LF-215U's two-stage design. This architectural difference does not preclude substitution for general-purpose applications but may affect EMI/EMC performance characteristics in noise-sensitive environments. The GTX-2160-Y22 specifies 50/60Hz operation, aligning with standard industrial AC frequencies.

Interface Consideration: Termination style differs between parts. The LF-215U uses M4 threaded posts; the GTX-2160-Y22 uses terminal block connections. Circuit board or harness modifications are required for mechanical integration.

Product Availability: The LF-215U is Last Time Buy status with 877 units in stock. The GTX-2160-Y22 is Active status with 1048 units in stock, ensuring long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can GTX-2160-Y22 directly replace LF-215U without modification?

A: Electrical substitution is valid. Mechanical integration requires termination interface adaptation due to different connection styles (M4 threaded posts versus terminal block).

Q: Does the single-stage configuration of GTX-2160-Y22 affect filtering performance compared to the two-stage LF-215U?

A: Configuration differences exist between the parts. Both are single-phase EMC/EMI line filters for general-purpose applications. Specific EMI/EMC attenuation characteristics depend on individual filter design and are not provided in the parameter set.

Q: Is the higher DC voltage rating (560V) of GTX-2160-Y22 a concern for 250V applications?

A: No. Higher voltage rating indicates greater design margin and does not compromise performance in lower-voltage applications. The 250VAC rating matches the original specification.

Q: What is the significance of the GTX-2160-Y22 having additional certifications (cUL, TUV)?

A: Additional certifications expand regulatory acceptance for international markets and specific industry standards. These do not replace UL approval but supplement it.

Q: Are there inventory considerations for selecting between LF-215U and GTX-2160-Y22?

A: LF-215U is Last Time Buy with finite stock (877 units). GTX-2160-Y22 is Active production with current inventory (1048 units). For new designs and long-term applications, GTX-2160-Y22 ensures supply continuity.

Q: What connector or adapter is needed for GTX-2160-Y22 integration?

A: Termination interface conversion from M4 threaded posts to terminal block connections is required. Specific adapter specifications depend on circuit board design and are outside the scope of this component equivalency reference.
