Key Parameters

Substitute Part Grouping Explanation

Substitution of the LF-210N with the GTX-2100-Y22 is based on the following alignment of critical electrical and mechanical parameters:

Compatible Parameters:

• Single Phase filter type maintained
• 250VAC rated voltage identical
• 10A current rating identical
• Chassis mount configuration identical
• ROHS3 compliance maintained
• Operating temperature range compatible (-25°C ~ 55°C for GTX-2100-Y22 vs -20°C ~ 55°C for LF-210N)

Differing Parameters:

• Configuration: LF-210N uses Two Stage; GTX-2100-Y22 uses Single Stage
• Voltage - Rated DC: LF-210N rated 250VDC; GTX-2100-Y22 rated 560VDC
• Termination Style: LF-210N uses Threaded Post (M4); GTX-2100-Y22 uses Terminal Block
• Frequency - Operating: GTX-2100-Y22 specifies 50/60Hz operation
• Product Status: GTX-2100-Y22 is Active production

The GTX-2100-Y22 provides equivalent or superior electrical performance for 250VAC/10A applications while offering higher DC voltage rating and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in 250VAC/10A Applications:

The GTX-2100-Y22 serves as the active production equivalent for the discontinued LF-210N. Both components maintain identical AC voltage and current ratings with chassis mount configuration. The GTX-2100-Y22 provides superior DC voltage rating (560V vs 250V) and extended operating temperature range (-25°C vs -20°C minimum).

Compliance Considerations:

The GTX-2100-Y22 carries formal approvals from cUL, TUV, and UL, whereas approval agency information is not specified for the LF-210N. Both components maintain ROHS3 compliance. The GTX-2100-Y22 is REACH Unaffected, while the LF-210N is REACH Affected.

Interface Modification Requirement:

Substitution requires termination interface adaptation. The LF-210N uses threaded post (M4) termination, while the GTX-2100-Y22 uses terminal block connection. System integration must accommodate this mechanical and electrical interface change.

Configuration Difference:

The LF-210N employs two-stage filtering topology, while the GTX-2100-Y22 uses single-stage configuration. This represents a difference in EMI/EMC filtering performance characteristics. Applications requiring specific attenuation profiles should evaluate this topology difference against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the GTX-2100-Y22 directly replace the LF-210N without modifications?

A: Electrical substitution is valid for 250VAC/10A applications. However, the termination interface differs: LF-210N uses threaded post (M4) while GTX-2100-Y22 uses terminal block. Physical installation and wiring connection methods must be adapted accordingly.

Q: What is the significance of the different DC voltage ratings (250V vs 560V)?

A: The GTX-2100-Y22 is rated for higher DC voltage (560V) compared to the LF-210N (250V). This provides greater margin for DC applications and does not restrict use in lower-voltage DC circuits. The 250VAC rating remains identical for both components.

Q: Does the single-stage versus two-stage configuration affect performance?

A: Configuration differences reflect different filter topologies. The LF-210N uses two-stage filtering while the GTX-2100-Y22 uses single-stage design. Both are rated for identical AC voltage and current. Applications with specific EMI/EMC attenuation requirements should verify that single-stage performance meets system specifications.

Q: Are there regulatory compliance differences between these parts?

A: Both components are ROHS3 compliant. The GTX-2100-Y22 carries formal approvals (cUL, TUV, UL) while the LF-210N approval agency is not specified. The GTX-2100-Y22 is REACH Unaffected; the LF-210N is REACH Affected. System compliance requirements should be evaluated against these certifications.

Q: Why is the LF-210N classified as Last Time Buy?

A: Last Time Buy status indicates discontinued production. The GTX-2100-Y22 is the active production alternative from KEMET for equivalent single-phase 250VAC/10A line filter applications.

Q: What is the operating frequency specification for the GTX-2100-Y22?

A: The GTX-2100-Y22 is specified for 50/60Hz operation. The LF-210N operating frequency is not specified in available documentation.
