Qualtek 848-20/004 Single Phase EMC/EMI Line Filter – Equivalent & Substitute Parts

Part Overview

The Qualtek 848-20/004 is a single phase EMC/EMI line filter rated for 20 A at 115V and 250VAC, operating at 50/60Hz with two-stage configuration and quick connect termination. This chassis mount filter is designed for general purpose applications requiring electromagnetic compatibility and electromagnetic interference suppression. The part maintains active product status with full RoHS3 compliance and international approvals including CSA, UR, and VDE certification. Substitute parts are identified when equivalent electrical performance, current rating, voltage compatibility, and mechanical mounting specifications align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Qualtek 848-20/004 are qualified based on the following critical parameters:

• Single phase filter configuration
• 20 A current rating
• Dual voltage compatibility (minimum 115V/120V and 250V AC)
• Two-stage filter topology
• Chassis mount mechanical form factor
• Quick connect termination interface
• 50/60Hz operating frequency
• General purpose application suitability
• RoHS3 compliance status
• International safety certifications (CSA, UR, VDE or equivalent)

Two substitute parts meet these criteria: the TE Connectivity Corcom Filters 20VS1 and the Schaffner EMC Inc. FN2060-20-06. Both maintain the same current rating, two-stage configuration, quick connect termination, and chassis mount design. Voltage ratings and frequency ranges vary within acceptable substitution parameters for this product category.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and RoHS3 compliance. Selection between the main part and substitutes depends on specific application voltage and temperature requirements.

The Qualtek 848-20/004 operates across -25°C to 85°C and supports both 115V and 250V AC inputs at 50/60Hz, making it suitable for standard industrial and commercial applications with moderate temperature variation.

The TE Connectivity Corcom Filters 20VS1 provides 120V and 250V AC operation at 50/60Hz with a narrower operating temperature range of -10°C to 40°C. This substitute is appropriate for controlled environment applications where temperature remains within specified limits. REACH status is affected for this part.

The Schaffner EMC Inc. FN2060-20-06 operates at 250V AC only with extended frequency capability (DC ~ 400Hz) and the widest temperature range (-25°C to 100°C). This substitute is suitable for applications requiring higher frequency operation or extended thermal performance. REACH status is unaffected.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 20VS1 replace the Qualtek 848-20/004 in all applications?

A: The TE Connectivity 20VS1 is electrically compatible for 250V AC operation and maintains the same 20 A rating, two-stage configuration, and quick connect termination. However, its operating temperature range (-10°C to 40°C) is narrower than the Qualtek part (-25°C to 85°C). Substitution is valid only when the application environment remains within the TE Connectivity temperature limits.

Q: What are the voltage differences between these three filters?

A: The Qualtek 848-20/004 and TE Connectivity 20VS1 both support dual voltage operation (115V/120V and 250V AC). The Schaffner FN2060-20-06 is rated for 250V AC only. For applications requiring 115V/120V operation, only the Qualtek or TE Connectivity parts are suitable.

Q: Does the Schaffner FN2060-20-06 work at 50/60Hz?

A: Yes. The Schaffner FN2060-20-06 operates across DC ~ 400Hz, which encompasses the standard 50/60Hz industrial frequency range. This extended frequency capability makes it suitable for applications with harmonic content or variable frequency operation.

Q: Are all three parts certified for the same safety standards?

A: All three parts hold CSA and UR certifications. The Qualtek and TE Connectivity parts include VDE approval. The Schaffner part includes CE and ENEC certifications in addition to CSA and UR. Selection should confirm that required certifications match application regulatory requirements.

Q: What is the difference in packaging between these parts?

A: The Qualtek 848-20/004 and Schaffner FN2060-20-06 are supplied in Tray packaging. The TE Connectivity 20VS1 is supplied in Bulk packaging. Packaging format may affect procurement, handling, and inventory management but does not affect electrical or mechanical compatibility.
