Key Parameters

Substitute Part Grouping Explanation

Substitution of the GF-220U is based on electrical and mechanical parameter compatibility within the single-phase EMC/EMI line filter category. The substitute part GTX-2200-Y03 maintains the following critical parameters:

Maintained Parameters:

• Filter Type: Single Phase
• Configuration: Single Stage
• Voltage - Rated AC: 250V
• Current Rating: 20A
• Mounting Type: Chassis Mount
• RoHS Status: ROHS3 Compliant

Modified Parameters:

• Voltage - Rated DC: Increased from 250V to 560V (higher rating, backward compatible)
• Termination Style: Changed from Threaded Post (M4) to Terminal Block (requires connection redesign)
• Frequency - Operating: Specified as 50/60Hz (GF-220U unspecified)
• Approval Agency: Expanded from UL to cUL, TUV, UL (enhanced certifications)
• Operating Temperature: Adjusted to -25°C ~ 55°C (slightly different range)

The GTX-2200-Y03 provides equivalent filtering performance with enhanced voltage rating and broader regulatory approvals. Termination style change requires mechanical redesign of connection interface.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The GTX-2200-Y03 serves as the manufacturer-recommended substitute for the GF-220U. Both components are KEMET single-phase EMC/EMI line filters with identical AC voltage rating (250V), current capacity (20A), and chassis mount configuration. The GTX-2200-Y03 provides enhanced DC voltage rating (560V versus 250V), making it suitable for applications previously served by the GF-220U.

Regulatory Compliance:

The GTX-2200-Y03 maintains ROHS3 compliance and expands regulatory approvals to include cUL and TUV certifications in addition to UL. This enhanced certification profile supports broader market applications.

Connection Interface Consideration:

The primary design change between these components is termination style: GF-220U uses threaded post (M4) connection, while GTX-2200-Y03 uses terminal block connection. Circuit board or wiring harness redesign is required to accommodate this change.

Inventory Status:

GF-220U is Last Time Buy with 779 units in stock. GTX-2200-Y03 is Active status with 706 units in stock, ensuring continued availability for future procurement.

Frequently Asked Questions (FAQ)

Q: Can GTX-2200-Y03 replace GF-220U in existing designs without modification?

A: Electrical substitution is direct for 250VAC/20A applications. However, the termination style change from threaded post (M4) to terminal block requires connection interface redesign. Mechanical mounting remains compatible as both use chassis mount configuration.

Q: What is the significance of the increased DC voltage rating (560V vs 250V) on GTX-2200-Y03?

A: The higher DC rating provides design margin and compatibility with a broader range of applications. For circuits designed for 250VDC operation, the 560V rating presents no compatibility issues and may improve component longevity under transient conditions.

Q: Are there frequency differences between these components?

A: GF-220U does not specify operating frequency. GTX-2200-Y03 is rated for 50/60Hz operation. Both are suitable for standard industrial and commercial power distribution applications operating at these frequencies.

Q: How do the operating temperature ranges compare?

A: GF-220U operates from -20°C to 60°C; GTX-2200-Y03 operates from -25°C to 55°C. The ranges overlap substantially. For applications within -20°C to 55°C, both components are suitable. Applications below -20°C or above 55°C require component-specific evaluation.

Q: What certifications does GTX-2200-Y03 provide beyond GF-220U?

A: GTX-2200-Y03 includes cUL and TUV certifications in addition to UL. These additional certifications support compliance requirements in Canadian and European markets.

Q: Why is GF-220U classified as Last Time Buy?

A: Last Time Buy status indicates KEMET has discontinued production of this model. GTX-2200-Y03 represents the active replacement in the product line, ensuring continued availability and support for new designs.
