GT-20302 LINE FILTER 250VAC 3A CHASSIS – Equivalent & Substitute Parts

Part Overview

The GT-20302 is a single-phase EMC/EMI line filter manufactured by KEMET, rated for 250VAC at 3A with a two-stage configuration and quick connect termination. This component is designated as Last Time Buy, indicating discontinued production status. Identification of equivalent substitute parts is necessary to ensure continued availability for new designs and replacement applications where the original part is no longer procurable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GT-20302 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Voltage rating: 250VAC minimum
• Current capacity: Equal to or greater than 3A
• Mounting configuration: Chassis mount
• Regulatory compliance: UL, TUV, or equivalent certifications
• RoHS compliance status

Substitution Logic: The GTX-2060-Y22 qualifies as a substitute part because it meets or exceeds all mandatory electrical and mechanical parameters. While the substitute exhibits differences in configuration (single stage versus two stage), DC voltage rating (560V versus unspecified for GT-20302), and termination style (terminal block versus quick connect), these differences do not preclude functional substitution in applications requiring 250VAC 3A filtration on a chassis-mounted platform.

Engineering Selection Recommendations

Primary Substitute: GTX-2060-Y22

The GTX-2060-Y22 is the manufacturer-recommended substitute for the GT-20302. Selection of this part is supported by the following factors:

• Regulatory Compliance: Both parts maintain UL and TUV certifications. The GTX-2060-Y22 includes cUL certification, providing expanded North American compliance coverage.
• Electrical Sufficiency: The substitute provides 6A current capacity, exceeding the original 3A requirement, and maintains 250VAC rating compatibility.
• Availability: The GTX-2060-Y22 is in Active product status with 1000 units in stock, ensuring procurement reliability compared to the Last Time Buy status of the original part.
• Environmental Compliance: Both parts are ROHS3 compliant and suitable for equivalent operating temperature ranges.
• Mechanical Compatibility: Chassis mount configuration is preserved in the substitute.

Design Considerations:

Termination style differs between the original (quick connect) and substitute (terminal block). Circuit board layout and connector interface design must be evaluated during implementation. The single-stage configuration of the substitute differs from the two-stage design of the original; filtering characteristics may differ and should be assessed for specific EMI/EMC requirements.

Frequently Asked Questions (FAQ)

Q: Can the GTX-2060-Y22 directly replace the GT-20302 without circuit modifications?

A: The GTX-2060-Y22 provides equivalent electrical performance for 250VAC 3A applications. However, termination style differs (terminal block versus quick connect), requiring interface adaptation. Mechanical mounting and connector compatibility must be verified for your specific application.

Q: What is the significance of the higher current rating (6A) on the substitute part?

A: The 6A rating on the GTX-2060-Y22 exceeds the 3A requirement of the original part. This provides additional design margin and thermal headroom. The substitute is suitable for applications requiring up to 6A; it will operate safely at the original 3A specification.

Q: Does the single-stage configuration of the GTX-2060-Y22 affect filtering performance compared to the two-stage GT-20302?

A: Configuration differences exist between the parts. Both are certified for EMC/EMI filtration at 250VAC. Specific attenuation characteristics and frequency response may differ. Application-specific EMI/EMC testing is required if filtering performance specifications are critical.

Q: Are both parts RoHS compliant?

A: Yes. Both the GT-20302 and GTX-2060-Y22 are ROHS3 compliant and suitable for applications requiring lead-free component specifications.

Q: What is the operational temperature difference between these parts?

A: The GT-20302 operates from -20°C to 55°C. The GTX-2060-Y22 operates from -25°C to 55°C, providing a 5°C lower temperature limit. Both are suitable for equivalent industrial and commercial temperature environments.

Q: Is the GTX-2060-Y22 the only available substitute?

A: The GTX-2060-Y22 is the manufacturer-recommended substitute listed for the GT-20302. This is the primary equivalent part for procurement and design replacement purposes.
