Qualtek 850-10/003 Single Phase EMC/EMI Line Filter Equivalent & Substitute Parts

Part Overview

The Qualtek 850-10/003 is an active single phase EMC/EMI line filter rated for 10 A at 115V and 250VAC, operating at 50/60Hz. This two-stage quick connect chassis mount filter is designed for general purpose applications requiring electromagnetic compatibility and electromagnetic interference suppression. The part maintains active product status with 645 units in current inventory. Substitute parts are identified when original stock becomes unavailable, when procurement lead times exceed project requirements, or when alternative manufacturers offer equivalent electrical and mechanical specifications within the allowed parameter ranges for this filter category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Qualtek 850-10/003 are qualified based on the following critical parameters that determine functional equivalence:

Mandatory Matching Parameters:

• Filter Type: Single Phase
• Configuration: Two Stage
• Current Rating: 10 A
• Mounting Type: Chassis Mount
• Termination Style: Quick Connect
• Voltage Compatibility: Minimum 250VAC rating (covers the 115V/250VAC dual rating of the main part)
• Frequency Range: Minimum 50/60Hz support
• Approval Agencies: CSA and UR certifications (core regulatory requirements)
• RoHS Compliance: ROHS3 Compliant

Allowable Variations:

• Operating temperature range may differ provided the part operates within -25°C to 85°C minimum
• Inductance values may vary within acceptable EMI/EMI filtering performance ranges
• Packaging format (Tray vs. Bulk) does not affect electrical equivalence
• Frequency operating range may exceed 50/60Hz (e.g., DC ~ 400Hz)
• Additional approval agencies beyond CSA and UR are acceptable

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain active product status and meet the core regulatory compliance requirements for this application category.

TE Connectivity Corcom Filters 10VW1: This substitute provides full electrical equivalence at the 250VAC rating. The part carries identical CSA, UR, and VDE certifications. The operating temperature range of -10°C ~ 40°C is narrower than the main part; applications requiring operation below -10°C or above 40°C must use the Qualtek 850-10/003 or Schaffner FN2080-10-06. The 10VW1 is available in bulk packaging with 1599 units in inventory.

Schaffner EMC Inc. FN2080-10-06: This substitute provides the broadest operating temperature range (-25°C ~ 100°C) and extended frequency support (DC ~ 400Hz). The part carries CSA and UR certifications with additional ENEC approval. The voltage rating of 110V/250VAC covers the main part's dual voltage specification. The FN2080-10-06 is available in tray packaging with 1332 units in inventory.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 10VW1 be used in applications requiring 115VAC operation? A: The 10VW1 is rated for 250VAC only. Applications requiring 115VAC operation must use the Qualtek 850-10/003 or Schaffner FN2080-10-06, both of which support dual voltage ratings of 115V/250VAC and 110V/250VAC respectively.

Q: What is the difference between the operating temperature ranges of these three filters? A: The Qualtek 850-10/003 operates from -25°C to 85°C. The TE Connectivity 10VW1 operates from -10°C to 40°C, making it unsuitable for applications requiring extended low-temperature operation. The Schaffner FN2080-10-06 operates from -25°C to 100°C, providing the widest temperature envelope.

Q: Are all three filters certified by the same regulatory agencies? A: All three filters carry CSA and UR certifications. The Qualtek 850-10/003 and TE Connectivity 10VW1 also include VDE certification. The Schaffner FN2080-10-06 includes ENEC certification in addition to CSA and UR. All certifications meet the core regulatory requirements for this product category.

Q: Does packaging format affect the electrical performance of these filters? A: No. The Qualtek 850-10/003 and Schaffner FN2080-10-06 are supplied in tray packaging, while the TE Connectivity 10VW1 is supplied in bulk packaging. Packaging format does not affect electrical equivalence or performance characteristics.

Q: Can the Schaffner FN2080-10-06 be used in DC applications? A: The Schaffner FN2080-10-06 supports DC operation as part of its DC ~ 400Hz frequency range. The Qualtek 850-10/003 and TE Connectivity 10VW1 are rated for 50/60Hz operation only and are not suitable for DC applications.

Q: What is the significance of the inductance specifications listed for these filters? A: Inductance values determine the filtering characteristics and EMI/EMC performance of the filter. The Qualtek 850-10/003 specifies L1 - 1.2mH and L2 - 40µH. The TE Connectivity 10VW1 specifies 1.2mH. The Schaffner FN2080-10-06 specifies 4.5mH. These variations are within acceptable ranges for single phase two-stage line filter designs and do not prevent functional substitution.
