GT-205U Line Filter Equivalent & Substitute Parts

Part Overview

The GT-205U is a single-phase EMC/EMI line filter manufactured by KEMET, rated for 250VAC at 5A with chassis mount configuration and threaded post (M4) 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-205U requires evaluation against the following critical parameters:

Functional Equivalence Criteria:

• Filter Type: Must be Single Phase EMC/EMI line filter
• Configuration: Must be Single Stage
• Voltage Rating (AC): Must support minimum 250VAC operation
• Current Rating: Must support minimum 5A continuous current
• Mounting: Must be Chassis Mount compatible
• Termination: Must accommodate M4 threaded post connection or equivalent mechanical interface

Compliance Criteria:

• Regulatory approvals must include UL and TUV certifications
• RoHS3 compliance required
• Operating temperature range must encompass or exceed -20°C ~ 55°C

The GTX-2060-Y03 meets these substitution criteria with enhanced specifications in voltage rating (560VDC) and current capacity (6A), while maintaining single-phase, single-stage configuration and chassis mount design. However, termination style differs from the original part.

Engineering Selection Recommendations

Primary Substitute: GTX-2060-Y03

The GTX-2060-Y03 is the manufacturer-recommended substitute for the GT-205U. Selection of this substitute is supported by the following engineering factors:

Electrical Compatibility: The GTX-2060-Y03 maintains equivalent AC voltage rating (250V) and exceeds the current requirement (6A versus 5A), ensuring functional compatibility in the original application circuit. The additional DC voltage rating (560V) provides enhanced capability without compromising AC performance.

Regulatory and Compliance Status: Both parts maintain UL and TUV certifications required for industrial EMC/EMI filtering applications. The substitute includes cUL certification, extending approval coverage to Canadian markets. Both parts are ROHS3 compliant, meeting environmental regulatory requirements.

Product Availability: The GT-205U is designated Last Time Buy with limited inventory (733 units). The GTX-2060-Y03 is in Active production status with higher inventory availability (1,166 units), ensuring long-term procurement viability.

Mechanical Consideration: The termination interface differs between parts. The original uses threaded post (M4) termination, while the substitute uses terminal block termination. Integration into the target application requires mechanical interface verification and potential connector redesign.

Frequently Asked Questions (FAQ)

Q: Can the GTX-2060-Y03 directly replace the GT-205U without circuit modification?

A: The GTX-2060-Y03 provides electrical equivalence in single-phase, single-stage EMC/EMI filtering at 250VAC with equal or greater current capacity. However, the termination interface differs (terminal block versus threaded post M4). Mechanical integration requires connector or wiring interface adaptation.

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

A: The 6A rating on the GTX-2060-Y03 exceeds the 5A requirement of the original application. This provides operational margin and allows the substitute to function in applications requiring up to 6A continuous current. The substitute remains suitable for 5A applications.

Q: Does the additional DC voltage rating (560V) on the GTX-2060-Y03 affect AC operation?

A: No. The DC voltage rating indicates the component's capability to withstand DC voltage stress. The AC voltage rating (250V) remains the controlling specification for AC applications. The higher DC rating does not alter AC filtering performance.

Q: Are both parts suitable for the same regulatory environments?

A: Both parts carry UL and TUV certifications required for industrial EMC/EMI applications. The GTX-2060-Y03 includes additional cUL certification for Canadian regulatory compliance. Both are ROHS3 compliant. Selection depends on target market regulatory requirements.

Q: What is the impact of the extended operating temperature range on the substitute?

A: The GTX-2060-Y03 operates from -25°C to 55°C, compared to -20°C to 55°C for the original. The substitute provides 5°C additional low-temperature capability, suitable for applications in colder environments. This represents an enhancement with no negative impact on standard temperature applications.

Q: Why is the GT-205U designated Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production of this model. Existing inventory is available for final orders, but no future production is planned. The GTX-2060-Y03 represents the active production alternative for continued component availability.

Q: What packaging format is used for both parts?

A: Both the GT-205U and GTX-2060-Y03 are supplied in Box packaging, suitable for industrial component distribution and storage.
