Key Parameters

Substitute Part Grouping Explanation

Substitution of the LF-215N is based on the following critical parameters:

Mandatory Compatibility Criteria:

• Single-phase filter type (application requirement)
• 250VAC rated voltage (circuit voltage compatibility)
• Chassis mount configuration (physical installation)
• ROHS3 compliance (regulatory alignment)

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 15A
• DC voltage rating: Substitute must equal or exceed 250V
• Configuration: Single-stage or two-stage acceptable (both provide EMC/EMI filtering)
• Termination style: Alternative connection methods acceptable if mechanically compatible
• Operating temperature range: Substitute must cover or exceed specified range

The GTX-2160-Y22 qualifies as a substitute based on these criteria, with specific trade-offs documented in the parameter comparison table.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The LF-215N is designated Last Time Buy, indicating end-of-life status. The GTX-2160-Y22 is classified as Active product, ensuring continued availability and supply chain reliability for future procurement.

Electrical Compatibility

Both parts maintain 250VAC rated voltage, satisfying the primary circuit voltage requirement. The GTX-2160-Y22 provides higher DC voltage rating (560V vs. 250V) and increased current capacity (16A vs. 15A), establishing margin above the LF-215N specifications.

Regulatory and Compliance Alignment

Both parts achieve ROHS3 compliance. The GTX-2160-Y22 carries additional third-party certifications (cUL, TUV, UL), providing enhanced approval documentation for regulated applications.

Physical Integration Considerations

Termination style differs between parts: LF-215N uses M4 threaded posts while GTX-2160-Y22 uses terminal block connection. This requires mechanical redesign of the connection interface. Both maintain chassis mount configuration.

Filtering Configuration Trade-off

The LF-215N employs two-stage filtering while GTX-2160-Y22 uses single-stage configuration. This represents a functional difference in EMC/EMI attenuation characteristics. Selection depends on specific EMI suppression requirements of the application.

Frequently Asked Questions (FAQ)

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

A: Electrical parameters are compatible. However, termination interface differs (threaded post vs. terminal block), requiring connection redesign. Verify mechanical mounting space and filtering performance requirements before implementation.

Q: What is the significance of the configuration difference (two-stage vs. single-stage)?

A: Configuration affects EMC/EMI filtering effectiveness and attenuation characteristics. Two-stage filters provide higher attenuation. Single-stage filters offer reduced complexity. Selection depends on specific EMI suppression requirements of the application circuit.

Q: Why does GTX-2160-Y22 have higher voltage ratings than LF-215N?

A: Higher ratings (560V DC vs. 250V DC) provide design margin and allow the substitute to function in applications with higher voltage headroom. This does not affect compatibility in 250VAC circuits.

Q: Are both parts RoHS compliant?

A: Yes. Both LF-215N and GTX-2160-Y22 are ROHS3 compliant. GTX-2160-Y22 additionally carries cUL, TUV, and UL certifications.

Q: What is the impact of different operating temperature ranges?

A: LF-215N operates -20°C to 55°C. GTX-2160-Y22 operates -25°C to 55°C. The substitute provides extended low-temperature capability, covering the original specification and exceeding it by 5°C.

Q: Is the 1A current rating difference significant?

A: GTX-2160-Y22 is rated 16A versus LF-215N at 15A. This 1A increase provides additional current capacity margin. For 15A applications, both parts are suitable.

Q: What packaging is available for both parts?

A: Both LF-215N and GTX-2160-Y22 are supplied in Box packaging.
