LF-210 Equivalent & Substitute Parts Reference

Part Overview

The KEMET LF-210 is a single-phase EMC/EMI line filter rated for 250VDC/VAC at 10A with a two-stage configuration and chassis mount design using threaded post (M4) termination. This component is classified as Last Time Buy, indicating discontinued production status. Identification of equivalent substitute parts is necessary to ensure continued availability for new designs and ongoing system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LF-210 is determined by the following critical parameters:

Critical Matching Parameters:

• Single-phase filter configuration
• 250VAC rated voltage (minimum requirement)
• 10A current capacity
• Chassis mount mechanical interface
• UL or equivalent safety certification

Acceptable Variation Parameters:

• DC voltage rating may exceed 250V (higher rating provides margin)
• Configuration may differ (single-stage acceptable for two-stage application)
• Termination style may differ if mechanical mounting is compatible
• Operating temperature range may be wider than specified
• Additional certifications (cUL, TUV) enhance compliance profile

The GTX-2100-Y22 qualifies as a substitute based on matching critical parameters while providing enhanced DC voltage rating (560V) and broader certification coverage.

Engineering Selection Recommendations

Primary Substitute: GTX-2100-Y22

The GTX-2100-Y22 is the manufacturer-recommended substitute for the LF-210. Selection of this part is based on:

1. Electrical Compatibility: Identical AC voltage rating (250V) and current capacity (10A) with enhanced DC voltage rating (560V), providing operational margin in DC applications.

2. Mechanical Compatibility: Both parts feature chassis mount design. Termination interface differs (threaded post M4 versus terminal block), requiring mechanical redesign of connection points.

3. Regulatory Compliance: GTX-2100-Y22 maintains ROHS3 compliance and expands certification coverage with cUL and TUV approvals in addition to UL certification.

4. Availability: GTX-2100-Y22 holds Active product status with 980 units in stock, ensuring supply continuity compared to LF-210 Last Time Buy status.

5. Operating Environment: Extended temperature range (-25°C to 55°C) accommodates broader environmental conditions than LF-210 specification.

Implementation Consideration: Termination style change from threaded post to terminal block requires circuit board or harness modification. Verify mechanical mounting clearance and electrical connection compatibility in target application before final selection.

Frequently Asked Questions (FAQ)

Q: Can GTX-2100-Y22 directly replace LF-210 without modification?

A: Electrical substitution is valid. Mechanical substitution requires modification due to termination style change from M4 threaded post to terminal block connection.

Q: What is the significance of the DC voltage rating difference (250V vs. 560V)?

A: The GTX-2100-Y22 higher DC rating (560V) provides operational margin and is compatible with applications rated at 250VDC or lower. No derating is required.

Q: Does the single-stage configuration of GTX-2100-Y22 affect filtering performance compared to two-stage LF-210?

A: Both configurations are single-phase EMC/EMI line filters rated for identical AC voltage and current. Configuration differences reflect design approach; both meet the specified electrical requirements.

Q: Are there packaging differences between these parts?

A: Both parts ship in Box packaging. Physical dimensions and mounting footprint may differ due to configuration and termination style variations. Verify mechanical specifications for PCB layout compatibility.

Q: What certifications apply to GTX-2100-Y22?

A: GTX-2100-Y22 holds cUL, TUV, and UL certifications, providing broader regulatory coverage than LF-210 (UL only).

Q: Is the frequency specification relevant for substitution?

A: GTX-2100-Y22 specifies 50/60Hz operation. This standard industrial frequency range is typical for single-phase line filters and does not restrict substitution eligibility.

Q: What is the REACH compliance status difference?

A: LF-210 is REACH Affected; GTX-2100-Y22 is REACH Unaffected. This difference reflects material composition and does not impact electrical or mechanical substitution compatibility.
